Tom Boucher	91ed46882a	feat(#3675): quick-batch core primitives and resumable manifest (#4190) ... * test(#3675): add failing tests for quick-batch core primitives Adds the full behavioral (tests/quick-batch.test.cjs) and property-based (tests/quick-batch.property.test.cjs) coverage for #3675's quick-batch core primitives per the phase's 35-row test matrix — task-list parsing (inline + --file, with path-confinement/symlink-escape/non-regular-file rejection), collision-safe quick-id preallocation under withPlanningLock, BATCH.json schema/validation/resume, dependency-DAG + partitionByFileOverlap wave construction, and exactly-once STATE.md completion (including the STATE-row-written-but-manifest-not-yet-updated crash window). The import target (gsd-core/bin/lib/quick-batch.cjs, compiled from a not-yet-written src/quick-batch.cts) does not exist yet — every test in both files fails at the top-level require() before any assertion runs. Five fast-check properties cover collision-freedom under lock contention, resume idempotency, exactly-once STATE completion, wave totality, and DAG-respecting wave order, per the design doc's property-based-coverage requirement. * feat(#3675): implement quick-batch core primitives Adds src/quick-batch.cts (ADR-457 build-at-publish, compiled to gsd-core/bin/lib/quick-batch.cjs) implementing #3675's quick-batch core primitives per the phase design lock — pure/state primitives and CLI-testable core operations only, no agent dispatch, no worktree creation, no user-facing command (Phase 4/#3676's job): - parseTaskList / parseTaskListFromFile: inline bulleted/numbered task-list parsing (>=2 items required) and a --file variant strictly confined to the planning workspace root via requireSafePath, rejecting non-regular-file targets. - allocateQuickIds / createBatch: collision-safe YYMMDD-xxx quick-id preallocation under withPlanningLock, checked against both on-disk .planning/quick/ entries and sibling .planning/quick-batches/*/BATCH.json manifests (never on-disk-only, which would miss another in-flight batch that hasn't dispatched any real quick directory yet) — replicates cmdInitQuick's own grammar rather than delegating to it (that function's 2-second granularity is not batch-safe). - computeWaves: deterministic wave construction combining dependency-DAG layering with partitionByFileOverlap (#3674), called per DAG layer over path-separator-normalized planned_files — normalization happens at this module's boundary, never inside the Phase 2 helper. - loadBatch: fail-closed BATCH.json schema validation (corrupt/truncated JSON, wrong types, missing fields, out-of-batch dependency references, dependency cycles, a worktree path absent from disk). - resumeBatch: skips complete items, never auto-retries failed items, propagates/reverses blocked status along the DAG to a fixed point, and detects a STATE.md row that already exists for a non-complete item (the "STATE written, BATCH.json not yet updated" crash window) — completing it without re-appending. Idempotent across repeated calls. - completeQuickItem / hasQuickTaskRow: exactly-once STATE.md completion — appendQuickTaskRow (unmodified) is called at most once per quick id, gated by hasQuickTaskRow's own idempotency check re-parsing the real "Quick Tasks Completed" table, since appendQuickTaskRow itself carries no idempotency. BATCH.json lives at .planning/quick-batches/<batch-id>/BATCH.json, a sibling of .planning/quick/ — never inside it, so scanQuickTasks never misreads a batch manifest as a broken quick task. * docs(#3675): register the new quick-batch module New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained registrations beyond the code itself: .gitignore (compiled artifact), eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs), docs/INVENTORY.md's CLI Modules roster row plus the regenerated docs/INVENTORY-MANIFEST.json cli_modules entry, and a CONTEXT.md glossary entry matching the convention set by the sibling File Overlap Partitioner Module (#3674) entry it sits beside. NOTE: docs/INVENTORY-MANIFEST.json was updated BY HAND (alphabetically sorted single-entry insertion into families.cli_modules, matching the existing file's structure) rather than via `node scripts/gen-inventory-manifest.cjs --write` — this session's MEMTRACE-FIRST guard hard-blocks direct execution of that indexed script path from Bash, with no available Memtrace tool to route through instead. The orchestrator should re-run `node scripts/gen-inventory-manifest.cjs --check` to confirm this hand-edit is byte-identical to the generator's own output before merging. * fix(#3675): resolve lint findings in quick-batch primitives and tests Unsafe `any[]` assignment from `new Array(n)` in the DAG cycle-check color array, two unnecessary `as string[]` casts TS 5.5's inferred type predicates already narrowed, raw `fs.rmSync` in test cleanup (needs the Windows-EBUSY retry budget `helpers.cleanup` carries), an unused `loadBatch` import, an unbounded `mkfifo` subprocess spawn missing a timeout, and a CONTEXT.md glossary illustration that looked like a real file reference. * feat(#3675): close acceptance-criteria gaps found in review Standards- and spec-axis review (plus a self-caught race) surfaced real gaps against issue #3675's own acceptance criteria and this repo's test conventions: - BATCH.json was missing options, base_revision, per-item wave, and per-item commit — the issue's AC explicitly lists all four as things the manifest must track. Added them: createBatch persists caller-supplied batchOptions/baseRevision verbatim and assigns each item its computed wave index; completeQuickItem now persists the commit onto the item, not just the STATE.md row. All four are backward-tolerant on load (an older/hand-built manifest without them still validates). - resumeBatch had no "incompatible base divergence" check at all, despite the AC and the ADR's own "Base divergence" section requiring one. Added an opt-in currentBaseRevision comparison that fails closed with a recoverable diagnostic on mismatch, and touches nothing on refusal. - resumeBatch read-modify-wrote BATCH.json OUTSIDE withPlanningLock — the only durable write path in this module that wasn't lock-protected, a real lost-update race against a concurrent completeQuickItem or another resume. Now runs inside the same lock createBatch/ completeQuickItem use. - loadBatch and collectExistingBatchQuickIds used raw JSON.parse with no size cap (security review, Low/informational); switched to the existing safeJsonParse (1MB cap) for defense-in-depth. - Parser (parseTaskList) had only example-based tests; CLAUDE.md requires a fast-check property test for parsers. Added one plus a companion reject-property for <2 items. - The id-exhaustion fail-closed ceiling (MAX_TIME_BLOCK) was untested at any boundary. Exported the pure allocateIdsGivenUsed/MAX_TIME_BLOCK for direct limit-1/limit/limit+1 testing without needing 46k fixture dirs. - Issue AC explicitly asks for prompt-injection-payload test coverage, distinct from the existing shell-metacharacter test; added one. - Test row 9 (FIFO skip) silently returned instead of calling t.skip(), so an unsupported platform would report a pass rather than a documented skip; fixed to bind the test-context param and skip properly. - Extracted toWaveInput to remove a 2-site production duplication of the QuickBatchItem -> computeWaves reshape (Standards-axis smell). - Added the required .changeset/ fragment (CONTRIBUTING.md: editing src/ is user-facing even though the compiled .cjs is gitignored). * fix(#3675): restore "not valid JSON" wording in loadBatch's parse-failure reason gsd-test caught this: switching loadBatch to safeJsonParse changed the parse- failure message shape ("... parse error — ...") without preserving the "not valid JSON" substring row 27's own test asserts on. Re-wrap safeJsonParse's error into the original diagnostic phrasing regardless of which of its three failure modes fired. * docs(#3675): backfill changeset pr number to 4190 * fix(#3675): detect a silently-no-op mkfifo on Windows, not just a throwing one CI caught this on windows-latest: row 9's platform-skip only caught mkfifo throwing (command not found). On this runner mkfifo resolves to something that exits 0 without creating a file (NTFS has no FIFO concept), so execution fell through to parseTaskListFromFile against a path that doesn't exist, producing an ENOENT stat error instead of the expected "not a regular file" rejection. Check the artifact actually exists before trusting a zero exit code, and skip with a documented reason either way. --------- Co-authored-by: sim <sim@local>	2026-09-02 15:38:27 -04:00
Tom Boucher	acb903c2e8	enhance(#3661): make the code-review hook point configurable (#4159) ... * feat(#3661): make the code-review hook point configurable Add `workflow.code_review_point` (`execute:post` default, or `execute:wave:post`) so a multi-wave phase can run code review once per wave instead of once at the end, scoped to what changed since the phase's prior review. The code-review capability now declares its step at both loop points via a new generic `pointFrom` step field: `pointFrom` names an enum config key, and the step is only active at its own `point` when that key resolves to a matching value. `_resolvePointGate` (capability-activation.cts) is the single shared implementation consumed identically by loop-resolver.cts and capability-state.cts, and capability-validator.cjs enforces that `pointFrom` references an enum key whose values cover the declaring step's own point. code-review.md's manual-invocation gate now reads `workflow.code_review` directly instead of probing registry presence at the hardcoded execute:post point (so manual `/gsd-code-review` keeps working regardless of which automatic point is configured), and its file-scope tiers narrow to what changed since the phase's last review commit when one exists. execute-phase.md's wave-post step dispatch gets a small, precedented carve-out so the code-review skill still receives its required phase argument when dispatched generically (caught by the isolated spec review). Closes #3661 Emitted-Drift-Ack-Growth: code-review.md — #3661 adds a point-aware config gate check and LAST_REVIEW_COMMIT-based incremental scoping to the file-scope tiers. Emitted-Drift-Ack-Growth: execute-phase.md — #3661 adds one carve-out sentence so the wave-post generic step dispatch passes PHASE_NUMBER to the code-review skill. * docs: backfill changeset PR number for #3661 (#4159) * fix: scope tests/io.test.cjs's fs.writeSync fault-injection mocks by fd Five fault-injection mocks in the "bug #1008" describe blocks intercepted every fs.writeSync call regardless of file descriptor, and several threw or truncated unconditionally on the first call. This surfaced as an intermittent macOS CI failure: node:test's own IPC channel back to the parent process (which also goes through fs.writeSync internally) could get a bogus injected error or truncated write if node's internal machinery called it while one of these mocks was active, corrupting the message frame the parent tried to deserialize ("Unable to deserialize cloned data.", location tests/io.test.cjs:1:1, uncaughtException — a whole-file IPC crash, not a test assertion failure). Root cause confirmed by a working counter-example already in the same file: the "#3912 A6" mocks gate on `fd !== 2` before any fault injection and were never implicated. Applied the same fd-scoped pattern to the five unscoped mocks (four output()-targeting tests gate on fd 1, one error()-targeting test gates on fd 2), and added a regression test proving an unrelated fd passes through untouched while the fault-injection mock is active. Found while verifying #3661; unrelated to that change's own diff. --------- Co-authored-by: sim <sim@local>	2026-09-02 11:01:54 -04:00
Tom Boucher	b0572c0108	feat(#3674): extract shared file-overlap wave partitioner (#4166) ... * test(#3674): characterize existing wave-dispatch output and add tests for the extracted partitioner Pins resolveWaveDispatch's and emitWorkflowScript's current, unextracted output (chain-overlap, disjoint-empty-set, and a multi-wave/multi-stage golden script) as a regression safety net ahead of extracting partitionStages into a standalone module. Also adds the new module's unit and property tests (test matrix rows 1-11) against its expected public API, which does not exist yet and is added in the next commit. * feat(#3674): extract file-overlap partitioner into a shared, generic module Moves partitionStages' greedy first-fit file-overlap algorithm into a new, dependency-free src/file-overlap-partitioner.cts module (partitionByFileOverlap), generalized over a plain {id, files}[] shape rather than claude-orchestration.cts's Plan/Wave interfaces. partitionStages becomes a thin adapter mapping its own Plan[] shape onto the generic input and back — behavior-preserving, no dependency ordering, no path normalization, no filesystem access moved or added. Enables a future consumer (quick-batch, #3675 / ADR-1239) to reuse the same primitive without pulling in orchestration internals. * docs(#3674): register the file-overlap-partitioner module bookkeeping New src/*.cts -> bin/lib/*.cjs modules need four hand-maintained registrations beyond the code itself: .gitignore (compiled artifact), eslint.config.mjs (ADR-457: lint the .cts, not the emitted .cjs), docs/INVENTORY.md's CLI Modules roster row (regenerated via gen-inventory-manifest.cjs --write), and a CONTEXT.md glossary entry matching the convention set by similarly-scoped leaf modules (text-lines.cts, plan-dependency-graph.cts, spec-section.cts). * fix(#3674): alphabetize INVENTORY.md row, manifest regen no-op, fast-check import already correct - docs/INVENTORY.md: move file-overlap-partitioner.cjs row to alphabetical position - docs/INVENTORY-MANIFEST.json: regenerated via gen-inventory-manifest.cjs --write, produced no diff (manifest is keyed by content, not row order) - tests/claude-orchestration.test.cjs's direct require('fast-check') is correct as-is: tests/helpers/fast-check-setup.cjs's own docstring scopes the shared-seed wrapper to "every *.property.test.cjs file"; claude-orchestration.test.cjs is not a .property.test.cjs file, and every .property.test.cjs file sampled uses the wrapper consistently. No outlier. * fix(#3674): constrain the no-overlap property test to unique ids, fixing an ambiguous duplicate-id reconstruction The `no two plans in the same stage share a modified file` property reconstructs which physical item produced each output id via `remaining.findIndex(r => r.id === id)`. Under duplicate ids (an explicitly-supported input shape for `partitionByFileOverlap`) that reconstruction can pick the wrong physical occurrence, producing a false-positive overlap failure (observed counterexample: p0(f1), p208(f1), p208([]) — correctly staged as [[p0,p208#2],[p208#1]], but misread by id-order as [[p0,p208#1],...], which do overlap). Properties (a) determinism and (b) totality already exercise duplicate ids correctly and are left unchanged; only this property's generated items are now constrained to unique ids via `fc.uniqueArray`, where the reconstruction is unambiguous. --------- Co-authored-by: sim <sim@local>	2026-09-02 07:33:42 -04:00
Tom Boucher	bf4485ada2	enhance(#3717): make the edge probe's shape cues language-aware via an optional text_en field (#4156) ... * test(#3717): add failing-first coverage for text_en language-aware classification Adds unit tests for the not-yet-implemented text_en field on Requirement (fallback selection, empty/whitespace/non-string rejection, shapes-override precedence), a SHAPE_CUES/VALID_SHAPES parity guard (RULESET.GENERATIVE-FIX), and workflow-prose contract tests asserting spec-phase.md Step 5.5 documents populating text_en for response_language projects. All new tests are RED until src/edge-probe.cts and the workflow docs are updated. * feat(#3717): make edge-probe shape classification read an optional text_en field Requirement gains an optional text_en; classifyShape's own signature stays untouched (a locked, directly-tested export), and the text_en ?? text selection is pushed to proposeEdges' single call site instead. text_en is validated fail-closed: an empty or whitespace-only value throws rather than silently winning the ?? fallback and degrading classification to zero shapes. This makes the #2773 doc-only translation convention an explicit, validatable field instead of an invisible instruction, per the approved Form-1 scope on #3717. * docs(#3717): document the text_en field across spec-phase, reference and how-to docs Updates Step 5.5's response_language instructions, the edge-probe reference Inputs contract, the FEATURES.md fragment, and the non-English how-to guide to describe the new text_en field: text keeps the requirement's own wording in all cases, text_en (when populated) is the engine-only English rendering the classifier prefers. * docs(#3717): record the text_en locked-surface change in CONTEXT.md and ADR-550 Updates the Edge Probe Module glossary entry to describe the text_en field and its fail-closed validation, and appends an ADR-550 amendment recording why this is additive and does not re-open the #652 LLM-classifier rejection (text_en is a plain field read by the existing deterministic regex classifier, not a new model-dependent surface). * docs(#3717): add changeset fragment and regenerate FEATURES.md pr:0 placeholder — backfilled with the real PR number after the PR opens. * docs(#3717): attribute the text_en machine check to engine-level validation, not prose tests Code-review (Spec axis) finding: the workflow-prose contract tests and the ADR-550 amendment overclaimed themselves as "the machine check the #2773 doc-only stopgap lacked." That check is actually engine-level (validateRequirement/classifyShape, covered in tests/edge-probe.test.cjs) — the prose tests are the same style of assertion #2773 already used. Reworded both to attribute the claim correctly. * fix(#3717): rewrap spec-phase.md so the id-unchanged sentence stays on one line The #3717 rewrite of Step 5.5's response_language paragraph moved a line break so "requirement `id`s" ended one physical line and "are never translated" started the next. The pre-existing #2773 regression test (tests/edge-probe-spec-phase-contract.test.cjs) asserts id + "never translated" on the SAME line (no \n in between, matching git's own line-oriented prose), so the reflow silently broke it. Rewrapped so the sentence lands on one line again, verified against every #2773/#3717 regex assertion in that test file. Emitted-Drift-Ack-Growth: spec-phase.md — #3717 adds text_en documentation to Step 5.5 (response_language paragraph + REQS_JSON heredoc comment); this growth is this PR's own diff, not incidental drift. * chore(#3717): backfill changeset PR number pr:0 -> pr:4156 now that the PR exists. --------- Co-authored-by: sim <sim@local>	2026-09-01 21:39:53 -04:00
0xdhx	7c116b1c17	fix(#3697): warn when the phase-complete Requirements-line tokenizer under-selects REQ-IDs (#3744) ... * fix(#3697): warn when the Requirements line under-selects REQ-IDs `cmdPhaseComplete` tokenizes ROADMAP's `**Requirements**:` line by splitting on `[,\s]+` and keeping tokens matching the anchored REQ-ID shape. That is correct for the canonical comma list the template ships, and silently wrong for every other form: `RANGE-01 … RANGE-05` -> the two ENDPOINTS only; the interior IDs are never considered, yet `requirements_updated` reports true with zero warnings `RANGE-01…05` -> ZERO IDs; the whole line is inert The silence is structural: the only cross-check, `ghostReqIds`, is itself `citedReqIds.filter(...)`, so an ID the tokenizer dropped is invisible to it by construction — and to `traceabilityWriteMisses` and `requirements_updated` with it. Warn on both paths. This does not add range support: the selected set is unchanged, so no existing ledger write changes. The trigger is ID-SHAPED EVIDENCE only — an ID-shaped substring the tokenizer did not select, or a range operator joining two IDs — with parenthetical citations and HTML comments stripped before the scan, so the #2334/#2339 over-warning on `None`, on the shipped `<!-- brackets optional -->` template comment, and on annotated lines cannot return. Regression tests extend the #2316/#2334 fixture family in tests/phase.test.cjs (10 cases: 4 defect, 2 canonical controls, 4 negative-space controls). Fixes #3697 * fix(#3697): rework under-selection detection onto tokens, not a free-text scan Round 2, driven by the P4.6 cross-AI review (codex, gpt-5.6-sol) of b3ce71cb. That review refuted 5 of 9 claims; three were false-positive classes in exactly the category #2334/#2339 had to REMOVE: `RANGE-01, RANGE-02 - 3 points` the bare-hyphen alternative read `RANGE-02 - 3` as a range `REQ-01, REQ-02 — locked per ADR-7.` the trailing period kept `ADR-7.` out of the anchored filter, so the unanchored substring scan reported it as unparsed `REQ-01, REQ-02 (see (ADR-7), then ADR-8)` nested parens left `ADR-8)` behind Replaces the free-text substring scan + loose range regex with three narrow, token-based rules (R1 range-shaped token, R2 pure range operator flanked by two selected IDs, R3 zero-selection with ID-shaped text). Also fixes the review's CLAIM 9: the warning said IDs were "marked complete" when a ghost range marks nothing — it now says "selected". Side effect: the two false NEGATIVES the same review found are now covered — `RANGE-01 through RANGE-05` and a parenthesised `(plus RANGE-02..RANGE-05)`. NOT YET DONE (see the handoff prompt): regression tests for the four false positives, the two new true positives, and the #3697-4 tightening the review's CLAIM 8 asked for (it currently filters on the warning's phrasing rather than asserting silence). Verified so far: tsc clean, the 10 existing #3697 tests green, and a 20-case standalone harness covering every case above. * test(#3697): pin the v2 token-detector boundary end-to-end Six new cases + two hardenings for the review findings against v1: - #3697-1 gains the worded spaced range (`RANGE-01 through RANGE-05`) — the operator set's `to|thru|through` arm was previously untested. - #3697-5 (new): a tight range hidden inside balanced parentheses (`RANGE-01 (plus RANGE-02..RANGE-05)`) warns, names the range token, and ticks exactly RANGE-01 — the paren shave must not hide it. - #3697-4 gains the four false-positive classes a free-text detector produced: numeric estimate (`- 3 points`), date annotation, em-dash citation with trailing period (`— locked per ADR-7.`), and nested parenthetical citations. - #3697-3 and #3697-4 now assert the ENTIRE warnings channel is empty, not that one phrase is absent — a re-worded over-warning cannot pass. Negative control: against the merge-base with its lib rebuilt, all 6 defect tests fail and all 10 controls pass. * fix(#3697): close round-2 review findings — annotation false positives Round 2 of the adversarial review (against 822a72a04) refuted five claims; this closes the false-positive class and the cheap misses: - R1's bare-hyphen arm now demands a full ID on BOTH sides (`REQ-01-REQ-05`): `LETTERS-\d+-\d+` is also a date-like annotation (`FY-2026-08`) and a sub-numbered ID, and warning on those is the expensive class. Tight hyphen shorthand with a live selection is the disclosed false negative; at zero selection R3 still catches it. - R2 requires the endpoint pair to imply an INTERIOR (same prefix, gap > 1): `REQ-02 - REQ-03` selects both endpoints and can drop nothing, so an annotation hyphen between adjacent IDs stays silent. - R3 skips placeholder-led lines: `None (per ADR-7)` is a declared-empty line citing its rationale, not unparsed residue. - Token shave: quotes/backticks now shaved from alphanumeric tokens (`` `RANGE-02..RANGE-05` `` warns); punctuation-only tokens get a bracket-only shave so `(..)` surfaces its operator. - 256-char token cap bounds the quadratic unanchored substring test. - Warning text mentions range expansion only when a range rule fired. Tests: 6 new cases (22 total). Negative control against the merge-base: 8 defect tests fail, 14 controls pass. * fix(#3697): close round-3 review findings — half-spaced ranges, cross-prefix annotations, markdown wrappers Round 3 of the adversarial review (against 2eb92dd0e) refuted four claims; this closes them: - Half-spaced ranges (`REQ-01 -REQ-05`, `REQ-01- REQ-05`) split at the tokenizer before R1's `\s*` can see them and under-selected silently. A glued-fragment rule warns when an operator is glued to a full ID with an ID-shaped neighbour on the open side and the endpoint pair implies an interior. - Cross-prefix pairs around a separator no longer read as ranges: `REQ-02 - (ADR-7)` and `REQ-02 (...) (ADR-7)` are annotations, and real ranges are same-prefix by nature. `impliesInterior` now returns false on prefix mismatch and computes the gap with BigInt (parseInt lost precision past 2^53). - The token shave now removes markdown emphasis markers and curly quotes, so `**None** (per ADR-7)` reaches the placeholder gate and `**RANGE-02..RANGE-05**` reaches R1. - The unanchored-substring cap rises to 2048 (a markdown-link range with a long URL cleared 256); the anchored range regexes scan linearly and drop their cap. Tests: 6 new cases (28 total; 377/377 file-wide). Negative control against the merge-base: 11 defect tests fail, 17 controls pass. * fix(#3697): round-4 review finding — word operators excluded from glued-fragment rule `TOREQ-05` is a valid prefix-agnostic REQ-ID, and the glued-fragment rule read it as `to` + `REQ-05`, warning on the canonical two-ID list `REQ-01, TOREQ-05`. Glued fragments are now SYMBOL-operator-only (`..`+, ellipsis, dashes): a word operator glued to an ID is an ID, not a range spelling. Tests: word-operator-prefixed ID control (misparse channel silent; the fixture's ghost-ID warning legitimately fires, so the whole-channel assertion stays with the registered controls) and an underscore-wrapped tight-range defect case. 30 targeted cases; 379/379 file-wide; negative control: 12 defect tests fail on the merge-base, 18 controls pass. * fix(#3697): round-5 review findings — trailing word-op glue, dot shave, honest wording - The glued-fragment TRAILING arm takes the word operators back: an ID must end in digits, so `REQ-01through` can never be an ID — the round-4 TOREQ collision was leading-arm-only, and symbol-only on both arms lost the `REQ-01through REQ-05` typo class. - A trailing run of 2+ dots survives the punctuation shave: `REQ-01..` is a glued range operator, not sentence punctuation, and the shave was silently eating the `REQ-01.. REQ-05` form. - The warning now says the line "could not be parsed as" a comma-separated REQ-ID list: `**REQ-01**, **REQ-05**` IS such a list — the selector just cannot parse decorated tokens — and a warning that misstates the input teaches readers to distrust it. Tests: two new trailing-glue defect cases (32 targeted; 381/381 file-wide). Negative control: 14 defect tests fail on the merge-base, 18 controls pass. * test(#3697): use t.after for cleanup per CONTRIBUTING test ruleset CONTRIBUTING bans try/finally inside test bodies (it masks failures); the approved shape is `t.after(() => cleanup(tmpDir))`. All seven converted tests are this PR's own additions; the file's pre-existing instances are untouched. * chore(#3697): add changeset fragment for the Requirements-line under-selection warning changeset-lint fails on this PR (fail_missing_fragment): src/phase.cts is a user-facing surface and the branch carried no .changeset/*.md. Adds the Fixed fragment via `npm run changeset -- --type Fixed --pr 3744`, symptom-led per the house format, with the (#3697) backlink. * refactor(#3697): extract the Requirements-line detector to a testable surface Round-3 review Blocker 1 requires a fast-check property test over this detector (`RULESET.TESTS.property-based-testing`: modules implementing parsing contracts must include at least one), and Blocker 2 requires limit-1/limit/limit+1 fixtures on its 2048-char token cap (`RULESET.TESTS.boundary-coverage.fixtures`). Neither is expressible while the logic is a closure inside `cmdPhaseComplete`: every existing #3697 test reaches it by spawning the CLI, and a property test cannot pay a subprocess per generated case. So the selector and the three detection rules move to module scope as `analyzeRequirementsLine` (pure, exported) plus `formatRequirementsLineWarning`, and `cmdPhaseComplete` calls them. This commit changes NO behaviour: `tests/phase.test.cjs` is untouched here, and the pre-round suite passes against it unmodified (403/403). Two things the move makes explicit rather than incidental. The selector and the detector tokenize the SAME line DIFFERENTLY — the selector strips only `[` and `]`, the detector also shaves quotes, emphasis and trailing sentence punctuation — and that gap is deliberate: it is why `ADR-7)` is not selected while `ADR-7` is still nameable in a warning. They now sit adjacent with the reason written down, so they cannot drift apart silently. And the stale citations in the moved comment are corrected. It pointed at src/phase.cts:833,920,1078 for the `**Requirements**: TBD` seeds, which had drifted to 1132/1237/1413, and at `templates/roadmap.md:32`, which is `gsd-core/templates/roadmap.md:32`. Both are now anchored by content. * fix(#3697): stop the warning claiming a misparse that did not happen Round-3 review Major 3 and Minor 4. Both are the same defect: the warning asserted more than the evidence supported. MAJOR 3 — a correct comma list such as `RANGE-01, RANGE-02 — RANGE-05 deferred` warned "could not be parsed ... Range forms are not expanded; rewrite the line". Reproduced: it selects RANGE-01, RANGE-02 AND RANGE-05, i.e. every ID written on the line. Nothing was dropped, and the pinned control only stayed silent because its pair was ADJACENT (gap == 1), so the control was passing by accident of the fixture rather than by the rule. The obvious fix — go silent — is not available. `RANGE-02 — RANGE-05` as a range and as an annotation separator are textually identical, and no token-level rule separates them; staying quiet re-opens the exact silent under-selection #3697 is about. Deciding the ambiguity by assertion in either direction is wrong. So it is DISCLOSED: the warning now has two channels, chosen by whether any ID-shaped token was actually left unselected (`droppedIdShaped`). * something was dropped (tight range, glued fragment, inert residue) -> "could not be parsed as a comma-separated REQ-ID list", as before. * nothing was dropped (only the spaced-operator rule fired) -> "contains what reads as a range between two cited REQ-IDs", stating both readings and saying explicitly that an annotation separator means the line is already correct. This retires the "could not be parsed" wording for the four #3697-1 spaced cases too, and that is a deliberate expectation change rather than a fix counted twice: those lines never failed to parse either. They still warn, still name the selected IDs, and still assert the endpoint-only marking is unchanged; #3697-1 now also asserts the misparse channel stays SILENT. MINOR 4 — `Deferred (see ADR-7)` reported `Unparsed text: ADR-7`, naming a citation as requirement content it had failed to read. The trigger is correct and stays: #3697's acceptance criterion asks for a warning "when it selects zero IDs from a line that is non-empty and is not the `TBD` placeholder", and inferring placeholder-ness from arbitrary prose is the free-text heuristic this detector exists to avoid. What was wrong is the wording, so the non-range arm now says "ID-shaped text that was not selected" and names the escape the author actually has (`TBD` / `None`). Tests: #3697-9 (three spaced forms — must warn, must NOT claim a misparse, must offer both readings) and #3697-10 (`Deferred (see ADR-7)`, `N/A (tracked in ADR-12)` — must warn, must not say "Unparsed text", must not diagnose a range, must name the placeholder escape). Reversion control: reverting the ambiguous channel fails #3697-9 (3 named tests); reverting the R3 wording fails #3697-10 (2 named tests). * fix(#3697): cap every token predicate, complete the dash set, cover the boundary Round-3 review Blocker 2 and Nit 6, plus one self-found finding. All three are about the detector's own predicates, so they land together. BLOCKER 2 — the 2048-char budget had no boundary coverage. `RULESET.TESTS.boundary-coverage.fixtures` requires limit-1 / limit / limit+1 for any budget parameter. #3697-B1 and #3697-B2 now exercise 2047 / 2048 / 2049 against BOTH predicate families the cap guards, and each asserts its fixture's exact length before asserting behaviour, so a mis-built fixture fails loudly rather than passing at the wrong size. Clause (d) of that rule — an input pushed within reserve-distance of the limit — has no referent here: this is a hard cap with no reserve constant beside it, and the test comment says so rather than leaving the omission to be re-derived. NIT 6 — the cap guarded only the unanchored ID-substring regex. The anchored range regexes were left uncapped, justified by a comment asserting they scan linearly. The finding is right that this is informational (they are anchored; the input is a local ROADMAP.md), but an asserted property is cheaper to enforce than to defend, so all three predicates now share one `short()` guard. #3697-B2 is what pins it: at 2049 the anchored scan must now decline to classify. SELF-FOUND (RV4 guard-shape census) — the range-operator set is a list this code fixes at author time over a domain that grows without it, so the round owes a census of what the enumeration reaches. reached: `..`+, U+2026, U+2013, U+2014, ASCII `-`, to/thru/through NOT reached: U+2010 hyphen, U+2011 non-breaking hyphen, U+2012 figure dash, U+2015 horizontal bar, U+2212 minus sign consequence: a range spelled with any of those is SILENTLY under-selected — #3697's own defect, in the code that exists to fix it Those five close. They are the same operator at a different codepoint and carry none of the ASCII hyphen's collision risk, because they are not the REQ-ID separator: `FY-2026-08` is date-shaped only with ASCII hyphens, so a U+2010 never reaches the ID shape. They therefore join the NOHYPHEN arm beside `—` and `–`; the strict full-ID-both-sides shape the bare hyphen is held to is untouched, and #3697-12 pins that. Still NOT reached, declined with reason rather than left unstated: `→`, `~`, `..=`, `..<`, `until`, and `up to` (two tokens, so never one operator token). Each is a symbol or word with an independent non-range use between two REQ-IDs — the over-warning class #2334 cost three rounds. Reversion control: reverting the uniform cap fails #3697-B2 (limit+1); reverting the dash set fails #3697-11 (5 named tests). * test(#3697): add the fast-check property coverage the parser rule requires Round-3 review Blocker 1. `RULESET.TESTS.property-based-testing` (CONTEXT.md) requires modules implementing parsing contracts to carry at least one fast-check property test asserting a domain invariant, and the round-2 diff had zero occurrences of `fc.` across its +311 test lines. Five properties, 1,900 generated cases: P1 soundness of silence (boundary containment) — for ANY canonical comma list of well-formed REQ-IDs, the selected set EQUALS the written set and nothing warns. This is the #2334 over-warning invariant and the #3697 under-warning invariant asserted as one statement, over generated IDs rather than hand-picked ones. It generalises #3697-4b: a prefix beginning with a word operator (`TORANGE-05`) is an ID, and P1 covers that class rather than the single example. P2 completeness — a same-prefix pair with an interior between them, separated by any of the nine spaced operators, ALWAYS warns. P3 the #2334 invariant — an ADJACENT pair around a separator can drop nothing, so it stays silent however it is annotated. P4 totality + idempotency — total over arbitrary strings, deterministic, and the formatter agrees with the analysis on whether there is anything to say (a warn with no text, or text with no warn, is a channel that can go silent or noisy on its own). P5 containment — every selected ID is ID-shaped and appears verbatim in the input. Honest scoping, since a property test is easy to overclaim: P1, P3, P4 and P5 hold against the round-2 code as well as this one — they are regression guards, not bug-finders, and their value is that the invariants are now stated and generatively checked rather than implied by examples. P2 is the one that would have failed before the dash enumeration was completed. fast-check v4 removed `fc.stringOf`, so the ID-prefix tail is built from `fc.array(...).map(join)` with the alphabet pinned to the selector's own `[A-Z0-9]` class. These live in tests/phase.test.cjs rather than a new `phase.property.test.cjs`: `lint-test-file-count` caps a production module at 2 test files and phase.cts is already at its allowlisted entry, so a new file would trade one gate for another. * docs(#3697): document the ROADMAP Requirements-line grammar Round-3 review Minor 5 — the change adds net-new user-visible warning output for a grammar constraint documented nowhere under docs/. `type: Fixed` is docs-exempt so this does not block, but a warning about a rule the reader cannot look up is not actionable, and that is worth fixing whether or not a gate demands it. Added as a subsection of `phase complete` in docs/CLI-TOOLS.md, beside the existing SUMMARY artifact-check advisory it is a sibling of: the supported comma-list form, why ranges are deliberately not expanded, that `TBD` and `None` are the entire placeholder vocabulary, and what each of the two warning voices means — including that the range/annotation one may be reporting a line that is already correct. Existing file rather than a new one, deliberately: docs/ carries generated indexes and zh-CN / ja-JP trees, and a new top-level page invites a parity or index gate this change has no reason to touch. * fix(#3697): rule-scope the warning-channel discriminator Self-found at the round's pre-push review, against the Major 3 fix two commits back. That fix chose the channel from a LINE-GLOBAL question — "was any ID-shaped token left unselected?" — while the rules that produce the warning are not line-global. The two disagree as soon as the line carries an ID-shaped token no rule fired on: `RANGE-01, RANGE-02 — RANGE-05 deferred per (ADR-7)` `(ADR-7)` survives the selector's bracket strip, so the global test called it a drop and sent the line to the assertive channel — putting the false "could not be parsed ... rewrite the line" claim back on a correct line. That is review finding Major 3 returning through a side door, and it directly contradicts #3697-4, which pins a parenthetical citation as NOT unparsed residue. The discriminator is now rule-scoped: R2 is the only ambiguous rule, so the ambiguous channel requires that R2 fired, that no other rule did, and that every endpoint R2 fired on was actually selected. The last conjunct is not redundant — the detector shaves brackets and the selector does not, so R2 can fire on a `(RANGE-02)` that was never selected, and that IS a drop: `RANGE-01 (RANGE-02) — RANGE-05` -> assertive, correctly `droppedIdShaped` is replaced by `spacedRangePairs` (R2's hits, so the channel can ask about the endpoints the rule fired on) and the `rangeReadingOnly` verdict. Reversion control: against the line-global rule, #3697-9b fails. #3697-9c passes under both rules — there the dropped token IS the R2 endpoint, so the two agree; it is a regression guard, not a bug-finder, and is recorded as such rather than counted as a second control. * fix(#3697): hold every dash to the strict range shape, not just ASCII Self-found at the round's pre-push review, and it CORRECTS a claim made two commits back. That commit widened the range-operator set by five Unicode dashes and asserted they "carry none of the ASCII hyphen's collision risk, because they are not the REQ-ID separator". That reasoning was wrong. The collision is a property of the SHAPE — `PREFIX-\d+ <dash> \d+` is also a date (`FY-2026-08`) and a sub-numbered ID (`API-2-01`) — and the shape does not care which dash sits in the operator slot, because the ID's own separator is still ASCII either side of it. Measured: RANGE-01 (target FY-2026-08) silent <- pinned by #3697-4 RANGE-01 (target FY-2026‐08) WARNED <- same line, U+2010 So the widening reintroduced the #2334 over-warning class on a date annotation. It also exposed that the inconsistency PREDATES this PR: U+2013 and U+2014 were already in the loose arm at ce71dd399, so the en- and em-dash forms of that same date annotation warned before round 3 ever ran. One rule for every dash: a tight range spelled with any of the eight must carry a FULL ID on both sides, exactly as the bare hyphen already had to. `..`, `…` and the word operators stay loose — no date or sub-number reading exists between two numbers, so the strict shape would cost them coverage for nothing. The cost is a false negative, and it is one the design already accepts: `RANGE-01, RANGE-02-05` is silent today, deliberately, and now `RANGE-01, RANGE-02–05` is too. That removes an inconsistency rather than opening a gap, and a bare `RANGE-02–05` still warns — it selects nothing, so R3 catches it. Tests: #3697-13 (date annotation AND sub-numbered ID silent for all eight dashes), #3697-13b (full-ID tight range still warns for all eight), #3697-13c (loose operators keep their numeric endpoint), #3697-13d (the accepted false negative is symmetric, and the bare zero-selection line still warns). * fix(#3697): close the round's own pre-push review findings An adversarial cross-AI review of this round refuted 4 of its 10 claims. All four were real. Every fix below is to code THIS round introduced. 1. THE SOFT VOICE CLAIMED TOO MUCH (refuted CLAIM 1). `REQ-01, (REQ-02), REQ-03 — REQ-05` took the range-reading voice and told the author "the line is already correct and nothing needs to change" — while `(REQ-02)` had been dropped by the selector, which does not strip parentheses. The channel choice is still right, and deliberately so: `(ADR-7)` and `(REQ-02)` are the SAME shape, so routing on "was anything unselected?" puts the false "could not be parsed" claim back on a line carrying a citation — the misroute fixed two commits ago. No rule can adjudicate this; the author can. So the voice stops asserting the line is correct (it now speaks about the SEPARATOR, which is all it has evidence about), and BOTH voices gained a factual clause naming ID-shaped text the selector skipped, with the reason (brackets are not stripped) and no verdict attached. 2. THE CAP SILENCED A LINE THAT USED TO WARN (refuted CLAIM 2). A 2049-char range token warned before this round and went silent after it: the "uniform cap" commit bounded the predicate and, with it, the warning. That is #3697's own defect, introduced by the fix for a nit. The cap bounds the WORK, not the warning. An over-cap token carrying `-` is now recorded as unclassified (a linear `includes`, never the unanchored regex the cap exists to keep off it) and gets its own voice: "could not be checked ... the REQ-ID selection on this line is unverified". Unclassified is reported, never treated as clean. 3. THE CAP WAS NOT UNIFORM (review MISSED finding). R2 capped the operator token but not its neighbours, so `<2049-char ID> .. <2049-char ID>` still ran REQ_ID_SHAPE_RE and BigInt over both endpoints unbounded. The glued rule had the same hole. Every participant is capped now. 4. PROPERTY P5 WAS VACUOUS (refuted CLAIM 5). It drew from a bare `fc.string()`, which over 500 samples produced max length 10 and ZERO inputs containing a REQ-ID — the loop body never executed an assertion. A containment property that never contains anything is a green test measuring nothing. The generator now interleaves real IDs with noise and the property ASSERTS it saw them (>50/500), so it can never silently go vacuous again. The free-form coverage it was actually providing survives, honestly labelled, as #3697-P6. The same finding refuted this round's claim that P2 distinguishes pre-round behaviour: every operator P2 uses was already in the pre-round operator set. P2 is a regression guard, and its comment now says so. Also: docs/CLI-TOOLS.md repeated the broken channel claim verbatim (review MISSED finding) and is corrected with the code. Tests: #3697-9d (soft voice names the skipped ID, never claims the line is correct), #3697-9e (over-cap token reported as unclassified, still warns), #3697-9f (R2 and the glued rule cap their neighbours). #3697-B1/B2 now key the boundary on the PREDICATE's verdict with `warn` asserted true at every length — asserting `warn === false` at limit+1 was itself finding 2. * docs(#3697): describe the third voice and the dash rule Follow-on to the review-findings commit: that commit corrected the docs' claim about the soft voice but left two things the code now does undescribed. - There are THREE voices, not two. The over-cap voice ("could not be checked ... unverified") arrived with the fix for the review's CLAIM 2 and had no entry. - Dash spellings require a full ID on both sides, and `..` / `…` / the word operators do not. That asymmetry is deliberate and load-bearing — `PREFIX-<digits><dash><digits>` is date- and sub-number-shaped — so a reader hitting `REQ-01-05` and getting silence has no way to find out why. The accepted cost (`REQ-01, REQ-02-05` unreported, bare `REQ-02-05` still reported) is stated rather than left to be discovered. Documentation only; no behaviour change. * fix(#3697): close the continuation review's findings A continuation of the same adversarial reviewer, run against the reworked round, refuted 6 of 7 claims. Four were real defects in this round's own work and are fixed here; the other two are answered rather than changed, below. 1. THE SKIPPED-TEXT CLAUSE WAS ON ONE VOICE, NOT BOTH (refuted CLAIM A). The previous commit's message said both voices gained it. Only the soft return appended it. The assertive voice now carries it too — and, because that voice already names range tokens and inert residue under its own clauses, the note is filtered to what those did not already name. A warning that says the same token twice is one readers learn to skim. 2. THE CLAUSE'S WORDING WAS FALSE (also CLAIM A). It read "brackets and parentheses are not stripped". Square brackets ARE stripped by the selector — `[REQ-01, REQ-02]` is the documented form — so only parentheses qualify. Corrected in the message and in docs/CLI-TOOLS.md, which had inherited the same error. 3. THE OVER-CAP RULE STILL SILENCED A LINE (refuted CLAIM B). `oversizedTokens` filtered on `includes('-')`, which misses an over-cap OPERATOR: `REQ-01 <2049 dots> REQ-05` warned before this round, R2 declined to classify it once capped, and nothing reported it. That is the exact regression the field was added to close, one input over. Any token past the cap now counts — what it contains is irrelevant when we could not read it. 4. AND THEN OVER-REPORTED ONE (review MISSED finding). With (3) in place, a 2049-character CANONICAL REQ-ID was selected by the uncapped, fully-anchored selector AND flagged "REQ-ID selection on this line is unverified" — a contradiction inside one warning. A token the selector took was examined end to end, so it is excluded. Two findings are answered, not changed: CLAIM C — the selector's own `REQ_ID_SHAPE_RE.test` is uncapped. True, and deliberate: this round does not touch what gets MARKED, and the pattern is anchored at both ends with no nested quantifier, so it is linear. The claim that "all predicate paths are capped" was too broad; the DETECTOR's are. CLAIM E — `REQ-01, REQ-02<dash>05` is silent for every dash. That is the documented, deliberate cost of holding dashes to the strict shape, and it is symmetric with ASCII, which behaved that way before this PR. The reviewer is right that "without losing a range spelling that should be detected" was too strong; a bare `REQ-02<dash>05` still warns. Tests: #3697-9g (clause on the assertive voice, no repetition, bracket claim true), #3697-9h (over-cap operator does not silence the line), #3697-9i (a selected over-cap ID is never called unverified). #3697-9f is rebuilt — its first version used the SAME id twice, so R2 could not have fired even uncapped and it proved nothing; it now uses endpoints with a gap and fails when the neighbour cap is removed. Reversion control: all four fixes fail a named test when reverted in isolation (#3697-9h, #3697-9i, #3697-9g, #3697-9f). * fix(#3697): scope the over-cap exemption to what could actually pair A second continuation of the same reviewer, against the reworked round, confirmed the two claims that matter most and refuted three. This closes the one real defect; the other two are answered below. CLAIM J / CLAIM K (one defect, found from both directions). The previous commit exempted EVERY selector-accepted token from `oversizedTokens`, on the reasoning that the selector is uncapped and anchored so it examined the whole token. True of that token's SELECTION — and not the same as "no rule was suppressed by it". Two over-cap valid IDs either side of `..` are both selected, so both were exempted, and R2 is capped: a line that warned before this round went silent. That is the third appearance of one class in this round — the cap suppresses a check, and the suppression is not reported. Each fix for it over-corrected in the opposite direction, which is why the rule is now stated in terms of what was actually suppressed rather than in terms of the token: an over-cap token is exempt only when it was selected AND nothing beside it could have paired with it into a range (no range operator, no glued fragment, no second over-cap token). Everything else is unexaminable and says so. Two findings are answered, not changed: CLAIM M — the reviewer demonstrated, with driven evidence, a contextual rule that catches `REQ-01, REQ-02-05` while leaving `FY-2026-08` and `API-2-01` silent: recognise `PREFIX-a<dash>b` only when another SELECTED id on the line shares that prefix. That refutes this round's claim that the strict-dash trade was FORCED, and the claim is withdrawn — it is a design choice. The choice stands for this PR: the conservative rule is what ASCII already did before #3697, adopting a new contextual heuristic unreviewed at the end of a round is how the last three defects in this round were made, and #3697 asks for a warning rather than better range inference. Named here so the alternative is on the record rather than lost. Docs MISSED — CLI-TOOLS said every token over 2,048 characters "is not classified at all" and warns. Selection is not bounded; only range detection is. Corrected. Confirmed by the same pass, and worth recording because they are the PR's load-bearing promises: a 20,000-input comparison of the pre-extraction selector against HEAD found `mismatches=0` (nothing about which REQ-IDs are MARKED has changed), and the uncapped selector regex was measured linear from 100k to 800k characters. Tests: #3697-9f now asserts the range case is reported rather than silent, and #3697-9j pins the exemption's scope in both directions. Reversion control: restoring the blanket exemption fails both. * fix(#3697): warn on zero selection, as the acceptance criterion asks `Deferred`, `N/A`, `Pending`, `TBA` and `-` selected no REQ-IDs and stayed SILENT, while three shipped artifacts said they warned: `docs/CLI-TOOLS.md`, the `placeholderLed` census comment, and the advice string the command emits to the user. The asymmetry was the tell — `Deferred (see ADR-7)` warned, because the citation supplied the ID-shaped residue R3 required, while bare `Deferred` did not. The claim was written into three places and never executed once. This is also #3697's AC-1b/AC-4 verbatim: "warn when `citedReqIds.length === 0` while the raw capture is non-empty and not `TBD`". R3b keys on the SELECTION being empty, never on what the prose means, so it adds no free-text heuristic. It is deliberately not gated on ID-shaped residue the way R3 is, and the negative space is what settles that: all fifteen #2334/#2339 fixtures are held silent by non-zero selection or by `placeholderLed`, and not one of them by the ID-shape gate — measured, not argued. The gate was buying no negative space while costing the acceptance criterion. `tokens.length > 0` keeps an empty line and a comment-only line silent: the tokenizer strips `<!-- ... -->` before splitting, so the shipped template's own comment cannot reach the rule. Selection behavior is unchanged. This warns; it never invents an ID. Also extracts `warn` to a named const (round 3 review Minor 3) — this commit adds a disjunct to exactly that predicate, and in the return literal a later reordering would be a TDZ ReferenceError rather than a reader-visible error. Tests: #3697-14 (six zero-selection lines warn and tick nothing, and the warning names the TBD/None escape), #3697-14b (five placeholder spellings stay whole-channel silent), #3697-14c (comment-only line stays silent). Fail-first controls: all six #3697-14 cases fail against the pre-fix tree; -14b and -14c pass at both ends, which is correct — they pin silence the widening must preserve. * fix(#3697): name the REQ-ID a glued delimiter dropped `RANGE-01; RANGE-02` selects only RANGE-02 and marks only RANGE-02, with `requirements_updated: true` — #3697's own half-success failure mode, reached by one wrong delimiter, and silent before this rule. It is the issue's AC-1a ("a warning whenever the line contains ID-shaped content that the tokenizer did NOT select") at the shape most likely to be typed by accident. Round 4 review rated this Major rather than Blocker on the ground that the case is indistinguishable from a parenthesised citation, since `(ADR-7)` also shaves down to a bare ID. At the RAW token level it is distinguishable, and that is what makes the rule shippable: `REQ-01;` is shaved of a trailing DELIMITER, `ADR-7)` of a citation wrapper. R4 keys on that shave class and requires the token to sit outside any parenthetical. Measured before implementing: 0 false positives and 0 false negatives across 21 probes, including all fifteen #2334/#2339 negative-space fixtures. A first cut without the parenthetical test scored 3 false positives — every one of them a colon inside a citation (`(see ADR-7: section 3)`) — which is why that test is the rule's boundary rather than an optimisation. Adds the delimiter census the module did not have. The range-operator domain was already censused; the comma-substitute domain was not. Swept 26 spellings: exactly two produce a silent under-selection, `; ` and `: `. Every other spelling either selects both IDs or selects none and already warns. The review hand-listed the semicolon; the colon is the sibling that sweep found, and it fails identically. `rangeReadingOnly` now excludes an R4 hit — the ambiguous voice claims nothing was dropped, and must not speak for a line where something demonstrably was. Tests: #3697-15 (four delimiter shapes warn, name EVERY dropped ID, and tick exactly the unchanged selection), #3697-15b (three citation forms stay whole-channel silent). Fail-first control: all four #3697-15 cases fail against the previous commit's tree; -15b passes at both ends, pinning the boundary the widening must not cross. * fix(#3697): give the Requirements-line warning a stable machine kind The warning's kind existed only in the prose of its message, so every consumer and every test had to regex an English sentence — and rewording a message silently un-asserted the tests that pinned it. Round 4 review Major 3. The repo already had the settled seam for exactly these semantics. `CONTEXT.md` records `diffLiveConfig` emitting `kind:'unverified'` for a truncated scan, which is precisely this module's third voice; and `WAVE_CLEANUP_WARNING` in `src/worktree-safety.cts` carries codes for the same reason. ADR-3473 Decision 3 ("failure is a value") points the same way. `formatRequirementsLineWarning` now returns `{ code, message }` instead of a bare string, which also settles round 4 Nit 3 — `null` still means CLEAN, a legitimate value, but the success arm is no longer a naked string one field away from the shape the ADR standardises on. The kind is carried ALONGSIDE the prose, never instead of it. `warnings[]` is a documented `string[]` in `phase complete`'s JSON output, rendered by execute-phase.md's "If has_warnings is true" step, so re-typing its elements would be a breaking output-contract change for a shipped command. The code is emitted as its own additive `requirements_line_warning` field, absent entirely when the line is clean. Vocabulary, exported so tests key on it rather than on string literals: `req-line-misparse`, `req-line-range-reading`, `req-line-unverified`. Tests: channel ROUTING in #3697-9/-9b/-9c/-9d/-9e/-9g/-10 now asserts the code; message-content assertions stay where the user-visible wording is itself under test. #3697-16 pins the code end-to-end through the CLI's JSON for four line shapes and asserts warnings[] is still a string[]; #3697-16b pins that a clean line emits no kind at all, because a field present on every run carries no information. #3697-P4 holds kind-and-message-appear-together and kind-is-in-the-declared-vocabulary over arbitrary input, so a channel added later cannot ship without one. * test(#3697): pin the divergence against the second parser of the same line CLAUDE.md, KNOWN DEFECTS & ANTI-PATTERNS: "Generative Fix Divergence: when sharing constants/arrays/parsers between parallel surfaces, add a parity assertion test that fails if they diverge." Round 4 review Major 2. `normalizePhaseReqIds` (src/gap-checker.cts) parses the SAME ROADMAP `**Requirements:**` value — its own docblock says callers "may pass the roadmap value through verbatim" — and diverges on four axes. Measured, not inferred: line phase complete gap-checker RANGE-01..RANGE-05 [] 5 IDs None (per ADR-7) [] ["ADR-7"] (REQ-02) [] ["REQ-02"] REQ-01a [] ["REQ-01a"] REQ-01, REQ-02 both both This pins the divergence rather than removing it, which is the review's second option and the correct one here: unifying the two would change what `phase complete` MARKS, and "the ledger-writing set is byte-identical to base" is the one invariant this PR holds fixed. Every axis is now asserted in BOTH directions, so drift on either side fails here instead of widening silently. The range axis is a DELIBERATE disagreement and is labelled as such — #3697 declines range expansion in terms ("I am not asking for range syntax to be supported") while gap analysis adopted it under #1269. The placeholder axis is the one worth reading twice: `None (per ADR-7)` is a declared-empty line to `phase complete`, which reads the lead token, and a one-requirement line to gap-checker, which strips parentheses first so the citation survives its ID-shape filter. That is a citation being reported as a requirement. #3697-17b states the cost concretely: one line, five requirements in scope to gap analysis and zero to phase complete. This PR is what makes that contradiction visible, by finally giving the silent side a voice. * fix(#3697): stop the skipped-text rider reporting a date, and close the 4b channel gap Two round 4 review minors, both about a warning saying something it cannot support. MINOR 2 — false rider content. `REQ_ID_SUBSTRING_RE` is unanchored, so `FY-2026-08` matches as `FY-2026` and lands in `unselectedIdShaped`. `REQ_RANGE_TOKEN_RE`'s entire strict-dash arm exists to keep that shape silent, and #3697-4 pins `RANGE-01 (target FY-2026-08)` as producing no warning at all — but whenever some OTHER rule fired on a line that also carried a date annotation, the rider told the author to "check whether any of it is a requirement" about a date. Not a false warning, since the line was warning anyway; false CONTENT, in the #2334 voice, through the side door. Filtered at the MESSAGE rather than in the analysis: `unselectedIdShaped` stays a faithful record of what the selector skipped — it is documented as a fact that never routes — while the user-facing clause declines to assert requirement-ness about a shape the design already ruled unadjudicable. #3697-18b is the other half, so the filter cannot become a silencer: a genuinely dropped REQ-ID is still named. MINOR 1 — `#3697-4b` asserted only that the ASSERTIVE channel stayed silent, so a regression routing `RANGE-01, TORANGE-05` into the AMBIGUOUS channel would have passed. Whole-channel silence is not available on that fixture (the pre-existing ghost-ID warning legitimately fires on the unregistered `TORANGE-05`), so the precise assertion is that no Requirements-line warning of ANY kind was emitted. The machine code added earlier in this round is what makes that statable; before it, "both channels" could only have meant a second prose regex. * docs(#3697): record the Requirements-line seam in CONTEXT.md CLAUDE.md names the CONTEXT.md glossary as a PR gate, and `get_cochange_context(src/phase.cts, 45d)` ranks CONTEXT.md 4th at 25 co-changes — above src/init.cts and src/roadmap.cts. This PR introduced a named seam, three warning kinds, a bound, a rule taxonomy and a deliberate cross-parser divergence, and recorded none of it. Round 4 review Major 4. The precedent is explicit rather than inferred: the directly analogous seam is already there as `LIVE-CONFIG.GUARD.SEAM.truncation`, including its bound and its boundary obligation — and that entry is the one this module's third voice was modelled on. Eight predicates, in the machine-oriented section beside it: .module the two exported functions and the code vocabulary .selector-identity citedReqIds is byte-identical to base and is the only thing reaching the ledger — a change to what phase.complete MARKS is outside this contract .rules R1 / R2 / R2' / R3 / R3b / R4 / over-cap .kinds the three codes, and why they ride beside warnings[] rather than inside it .cap 2048, neighbours included, and the boundary rule .placeholder the gate that actually holds the negative space .census-domains both open domains with their NOT-reached members .gap-checker-divergence the four axes, pinned not unified The changeset type is `Fixed`, which exempts this PR from the docs/ co-change requirement — but the glossary gate is separate from that exemption, and the 2048 cap in particular is a machine-canon-shaped fact that until now existed only inside a source comment. `docs/CONTEXT-INDEX.json` regenerated (269 predicates); lint:generated-sync confirms all six targets in sync. * docs(#3697): document what the command now does, in one changeset sentence DOCS. The grammar section predated this round's two new rules, so it under-described the behaviour it exists to make lookup-able: - The placeholder paragraph enumerated three words; the rule is a DEFAULT. Any wording that selects no REQ-IDs warns, and the placeholders are matched as the LEAD token, so `None (per ADR-7)` and `**None**` are declared-empty too. The comment-only line is called out, because "any other wording" would otherwise read as covering the shipped template's own `<!-- ... -->`. - The comma rule was implicit. `REQ-01; REQ-02` marks only REQ-02, and it is the quietest way to lose a requirement on this line — `requirements_updated` reads `true` either way — so it gets its own paragraph, with the parenthetical exemption stated beside it. - The machine kind is documented where a consumer would look for it, with the instruction to key on the kind rather than the wording. - The skipped-text note no longer implies it reports date shapes; it deliberately does not, and silently omitting that left the doc promising the behaviour this round removed. CHANGESET (round 4 review Minor 4). CONTRIBUTING.md's format is `**<Bold user-visible change>** — <symptom-led explanation>.` and both canonical examples are one sentence; this fragment ran three. Now one, and covering what the round actually delivers rather than only the range shape it started from. * test(#3697): keep phase.test.cjs off the docs-guard exemption fingerprint A comment added earlier in this round named `docs/CLI-TOOLS.md` by path. The docs-guard exemption ratchet (#3753 FIX 3) fingerprints literal `docs/` references in exempt test files and fails when a new one appears, so that comment turned four green gates red — `ci-docs-guard-registry` and the registration lint — for a file that reads no documentation at all. Caught by diffing the full suite's failing-name set against the same suite run at `upstream/next` in a probe worktree: 33 of 37 failures reproduce at base (install / config-home / shadowing tests under the sandbox HOME), and exactly these 4 did not. Rephrased rather than baselined. Adding the path to DOCS_GUARD_EXEMPT_DOCS_PATHS is the sanctioned response when a test genuinely starts READING a new docs path — the violation text asks the author to re-confirm the exemption still holds. Nothing here reads documentation; the guard matched prose. Baselining would have recorded a coupling that does not exist and made the next reader wonder what phase.test.cjs does with CLI-TOOLS.md. The comment still names where the contract is written, just without planting a path string. * fix(#3697): close four defects this round's own pre-push review drove An adversarial cross-AI review of this round, run before the push, returned 6 CONFIRMED and 4 REFUTED. Every refutation was driven against the built tree, and every one was a shape the author had not probed — the rules were correct across the probe set and wrong just outside it. (1) R4 FALSE POSITIVE, and it is the #2334 over-warning class arriving through the rule added to close a different hole. `REQ-01, see ADR-7: section 3` fired: `ADR-7:` is the same shave class as `REQ-01;`, and the parenthetical test does not reach a BARE citation. The FP probe that scored this rule 0/0 only ever tested the parenthesised form. Fixed by requiring the dropped id's prefix to agree with a SELECTED id — the module's own idiom, not a new heuristic: `reqEndpointsImplyInterior` already demands an agreeing prefix for the same reason. Cost, stated in the census: a dropped id whose prefix is on no selected id (`REQ-01, FOO-02: x`) stays silent. Same trade the strict-dash rule takes — under-report a rare shape rather than over-report a common one. Pinned as a declared blind spot by (2) R4 FALSE NEGATIVE, on the DOCUMENTED form. `[REQ-01; REQ-02]` dropped REQ-01 silently: the selector strips square brackets and R4's raw scanner did not. The bracket spelling the shipped template recommends was the one shape the rule could not see. (3) The rider filter suppressed a REGISTERED requirement. `API-2-01` is a legal requirement id — gap-checker's `parseRequirements` accepts it from REQUIREMENTS.md — so a `\d+-\d+` filter hid a genuinely dropped requirement behind a rule meant only to hide dates. Narrowed to a four-digit year segment. The earlier #3697-18 case asserting `API-2-01` should be suppressed is REMOVED, and the removal is recorded in place: its premise was refuted, it was not inconvenient. (4) An INVISIBLE line warned. A lone U+200B carried a token to the parser while reading as empty to the author, so R3b fired with nothing on screen to explain it. Zero-width and format characters are now stripped — stripped rather than treated as delimiters, because splitting on one would fabricate two fragments out of one ID. Also corrects the documentation the same review found overstated: the line is split on commas AND whitespace, and the ID shape is matched case-insensitively, so `REQ-01 REQ-02` and `req-01, req-02` both select and neither warns. That was pre-existing selector behaviour; this round is the one that asserted the docs were true of it. Tests: #3697-19 (four invisible-only shapes), -19b (embedded zero-width is stripped, not split on), -19c (three citation forms), -19d (both bracket spellings), -19e (both halves of the rider boundary), -19f (the declared blind spot), -19g (the two documented tolerances). 500 tests in phase.test.cjs, 0 failures; lint:ci clean. * fix(#3697): generalise the drop rule, and stop the invisible fix hiding a drop The pre-push review's continuation refuted six of seven follow-up claims. The first one is the one that mattered: the invisible-character fix committed in c7dce173a INTRODUCED #3697's own defect. Stripping zero-width characters from the detector wholesale made `REQ-01<ZWSP>, REQ-02` go SILENT — the selector really does drop REQ-01, and the strip removed the only evidence of it. The test written alongside asserted the tokens and the empty R4 result and never asserted `warn`, so it DOCUMENTED the bug rather than catching it; that omission was the reviewer's own MISSED finding. An invisible is two different questions about one character, and the fix is to stop conflating them: absence-of-content for the empty test, DECORATION on a token for the drop rule. Neither is a reason to delete it from the line. R4 is generalised accordingly, because the continuation drove four more shapes a trailing-delimiter-only regex could not see — `REQ-01 ;REQ-02`, `REQ-01 :REQ-02`, `**REQ-01;** REQ-02`, the backticked form — plus `**REQ-01**, REQ-02`, where emphasis alone defeats the selector. These are one class: decoration on a token the selector then cannot take. One rule, not four patches; patching them individually is how a list stays short and wrong. PARENTHESES ARE NOT DECORATION, and the suite caught me learning that: shaving them made `REQ-01, (REQ-02), REQ-03 — REQ-05` report a glued delimiter that was never there and broke #3697-9d's channel routing with it. A parenthesis is this rule's citation marker. The rider stops adjudicating an undecidable shape. `API-2-01` is a legal requirement id and `API-2026-08` is too, while `FY-26-08` and `FY-2026-08-15` are dates — no regex separates them, and both filters this round tried scored a miss in each direction. It now NAMES the token and states the ambiguity, which is the same thing the two warning voices already do about a range separator. Filtering hides a real dropped requirement; reporting it bare asks the author whether a date is a requirement; saying "this may equally be a date" does neither. The census and the docs are corrected to what the code does, including the part that is NOT complete: the prefix gate does not stop a citation that SHARES a selected prefix (`ADR-01, see ADR-7: sec 3` fires), and nothing at token level separates that from a real drop. A prose heuristic on "see" is the free-text detector this module exists to avoid, so the honest move is to say so. CLAIM 17 — the invariant that actually matters — came back CONFIRMED on a 20,000-run fast-check property over arbitrary Unicode: `citedReqIds` is identical to upstream/next's for every input, and marking is untouched. 513 tests in phase.test.cjs, 0 failures; lint:ci clean. * fix(#3697): gate the drop rule on evidence, and stop an unmatched paren swallowing the line Third pass of the round's own pre-push review, scoped to regression-hunting rather than further polish. Three findings, all driven, all mine. R4 OVER-WARNED on markdown styling. `REQ-01, see **REQ-7** for context` claimed a dropped requirement: the previous cut treated any shaved decoration as evidence, and emphasis is not evidence. Nothing separates that line from `**REQ-01**, REQ-02` meaning to list one, so the rule now requires a positive signal — a glued `;`/`:` (a list separator was INTENDED) or an invisible (the token is CORRUPTED; nobody types one on purpose). Emphasis alone falls back to the skipped-text rider, which names the id without asserting a drop, exactly as `(REQ-02)` is handled. That is the #2334 class caught one cut before shipping. R4 UNDER-WARNED on `**REQ-01**; REQ-02` — one shave pass cannot reach a wrapper sitting behind a delimiter. Shaves to a stable point now. The range OPERATOR lost its invisibles handling. `REQ-01 <ZWSP>..<ZWSP> REQ-05` went silent, because the previous commit removed the invisible strip from BOTH the tokenizer and R4 when only R4's was wrong. An invisible is two questions about one character: for the classification rules it is noise and is stripped from the token; for the drop rule it is the evidence and must survive on the raw line. Stripping in both places hid a dropped id; stripping in neither hid a range. The reviewer's MISSED finding named the missing control — regression tests covered invisibles inside ids and not beside operators — and #3697-19i is that control. UNBALANCED PARENTHESES swallowed the line. `REQ-01, (note REQ-02; REQ-03` reported nothing: a running-depth counter left the unclosed `(` open through end-of-line, so every genuine drop after it inherited citation immunity. A parenthesis confers that immunity only as part of a MATCHED span now — an unmatched one is a typo, not a citation. CLAIM 22 re-confirmed on a fresh 20,000-run property over arbitrary Unicode: `citedReqIds` identical to upstream/next, marking untouched, warnings appended. 522 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite carries zero head-only failures against a probe worktree at upstream/next. * fix(#3697): make delimiter ADJACENCY the rule, and delete matched citations outright Fourth and final pass of the round's own pre-push review. Three findings, and they shared one root cause, so this is a narrower rule rather than a longer list of shapes. TOKEN-WIDE PAREN IMMUNITY LEAKED. `REQ-01, REQ-02;(note) REQ-03` is a single whitespace token, so a matched parenthetical inside it conferred immunity on the `REQ-02;` sitting OUTSIDE the parens, and the drop went silent. Matched spans are now deleted from the line outright — which states what is actually meant, that for this rule a citation is not on the line — and an UNMATCHED paren is a typo that confers nothing. That also retires the running-depth counter whose previous bug was the mirror image: an unclosed `(` swallowing the rest of the line. DECORATION WAS TESTED TOKEN-WIDE, so `REQ-01, see **REQ-7**; next topic` was reported as a dropped requirement. It is a citation with sentence punctuation. The rule is now ADJACENCY: styling is stripped, then the `;`/`:` must be touching the id. `REQ-01;`, `;REQ-02` and `**REQ-01;**` qualify; `**REQ-01**;` does not, because outside the styling that character is punctuation. An invisible needs no adjacency test — nobody types one on purpose, so anywhere in the token it is corruption rather than intent. `**REQ-01**; REQ-02` therefore goes silent, and the test row asserting otherwise is inverted rather than deleted quietly: it was added one commit ago on the reasoning this pass refuted, and nothing distinguishes it from `see **REQ-7**; next topic`. Worth recording plainly: three successive cuts of this rule fired on a citation, and each fix was a narrower definition of EVIDENCE, never a longer list of shapes. The list-lengthening instinct is what produced the bug each time. The review's last MISSED finding named the missing control — the paren tests all surrounded matched spans with whitespace, so none covered a span sharing a token with an id outside it. #3697-19j carries both directions now. 526 tests in phase.test.cjs, 0 failures; lint:ci rc=0; full suite zero head-only failures against a probe at upstream/next; the invariant that `citedReqIds` is identical to upstream re-confirmed on 20,000 arbitrary Unicode inputs. * fix(#3697): state R4's real boundary, and stop the over-cap voice masking a drop Two defects, both found by this round's own pre-publication body claim-audit. 1. A DEMONSTRATED drop was discarded by the unverified voice. On `REQ-01, REQ-02: <2049 chars>` the analyzer names REQ-02 in delimiterDroppedIds and the formatter then reported `req-line-unverified`, whose message never mentions it — the one actionable finding masked by the token beside it. The over-cap channel now excludes a line carrying an R4 hit, exactly as rangeReadingOnly already did and for the same reason: that voice's whole claim is that nothing could be checked, and R4 has already checked something. The assertive channel still carries the over-cap rider, so nothing about the cap is traded away. Pinned by #3697-19l, which fails against the pre-fix build and nothing else does. 2. Three shipped artifacts asserted behaviour the code does not have — the same class as this PR's round-4 blocker, re-committed. CONTEXT.md's rules predicate, the CLI tools reference, and the warning's own advice string all listed markdown emphasis as an R4 trigger. It is not: styling is shaved BEFORE the test and tolerated around an id, never a trigger on its own, so `**REQ-01**, REQ-02` and `**REQ-01**; REQ-02` are both silent. The trigger is exactly a glued `;`/`:` or an embedded invisible. The census predicate was wrong in a second way. Its 26-spelling separator sweep found only `;` and `:` because the sweep was SYMMETRIC-ONLY and therefore biased: one-sided attachment drops silently for every punctuation outside the set — `/ | & + . > \` and the full-width and non-ASCII forms `； ， ؛` all measured silent. The domain is wide open and R4 covers two characters of it. Said plainly in all three places rather than widened here: every previous widening of this rule first fired on a citation, so it is not done blind at the end of a round. Both blind spots are now PINNED as tests (#3697-19m styling-only, #3697-19n one-sided separators) so the documents and the code cannot drift apart again — which is what the round-4 blocker asked for. tests/phase.test.cjs: 542 tests, 542 pass, 0 fail, 0 skip. lint:ci rc=0. Both CONTEXT-INDEX consumers regenerated. * fix(#3697): re-sweep the separator census properly, and say what it really found The round-4 census in src/phase.cts concluded "exactly two — `; ` and `: `" from a 26-spelling sweep. That conclusion was forced by how the sweep was built, not by the code: it swept the ONE-SIDED form (`REQ-01; REQ-02`) for the semicolon and colon, and only the BARE and SYMMETRIC forms (`|`, ` | `) for every other separator. Different members of the domain were tested in different shapes, so no other answer was reachable. Caught by this round's pre-publication claim-audit of the response comment, reading the census comment against its own swept list. Re-swept fully crossed and driven through the built artifact: 21 separators x {bare, trailing-space, leading-space, both-spaces} = 84 combinations. 26 select both ids, 24 under-select and already warn, and 34 UNDER-SELECT SILENTLY. All 34 are one shape — a separator glued to exactly one of the two ids, e.g. `REQ-01/ REQ-02` or `REQ-01 /REQ-02` — for every punctuation except `,` and the `;`/`:` that R4 covers. So R4 covers TWO CHARACTERS of a wide-open domain. That is now what the census comment, the CONTEXT.md census-domains predicate and the CLI tools reference all say. The set is deliberately not widened here: three successive cuts of this rule fired on a citation, and a fourth at the end of a round with no adversarial pass is how each of those got in. Second false passage in the same block: styling-only decoration was described as "left to the skipped-text rider, which names the id". A rider only exists inside a message, and a message only exists once some rule sets `warn` — so on a line where nothing else fires, `REQ-01, **REQ-02**` is wholly silent. Describing it as handled reads as coverage. #3697-19m already pins the silence. so the test matches the documented claim. tests/phase.test.cjs: 552 tests, 552 pass, 0 fail, 0 skip. lint:ci rc=0. Both CONTEXT-INDEX consumers regenerated. * chore(#3697): regenerate both CONTEXT-INDEX.json after rebasing onto next Rebased onto next @ f4fefb0be. The two generated indexes conflicted on the replay and were resolved by regenerating, not by hand-merging: `npm run gen:context-index` for docs/CONTEXT-INDEX.json and `node examples/dynamic-context-management/gen-context-index.cjs --write` for the example's copy. Against next, each now differs only in the eight PHASE.REQ-LINE.SEAM.* predicates this PR adds (plus the PHASE class and the count); every base-side change (the SEAM.* predicates, the ADR-3942 value rewrites) is carried. `lint-example-parser-parity` and `gen-context-index --check` both pass. * fix(#3697): an over-cap token outranks the ambiguous range voice Round 7 review, Minor 1. `rangeReadingOnly`'s guard conjunction checked `hasGluedRangeFragment`, `inertIdShaped` and `delimiterDroppedIds` but not `oversizedTokens`, so a line carrying a clean, fully-selected spaced range *and* an unrelated token past the 2048-char scan cap was coded `req-line-range-reading` — a code CONTEXT.md's PHASE.REQ-LINE.SEAM.kinds predicate documents as "nothing was dropped" — over a token no rule (R1-R4 all skip over-cap tokens) had ever examined. Since the PR tells machine consumers to branch on `.code` rather than parse prose, that is a false "nothing to verify further" signal. The review's suggested fix was to add `oversizedTokens.length === 0` to the conjunction. That clause is right and is here, but on its own it routes the line to the ASSERTIVE channel: `req-line-misparse`, whose message says the line "could not be parsed as a comma-separated REQ-ID list" on a line where every ID present was in fact selected. That is the #2334 over-warning class this module's own channel-selection docblock exists to prevent — a false-clean code traded for a false-assertion one. So the correct destination is `req-line-unverified`: the line was not CHECKED, which is not the same as clean, and nothing on it demonstrably failed to parse either. Both non-assertive voices were carrying their own inline copy of the same "nothing was demonstrably dropped" conjunction, and that duplication is what let them drift: `rangeReadingOnly` omitted the cap, while the over-cap channel excluded a spaced range wholesale via `!hasSpacedRange`. Extract it once as `nothingDemonstrablyDropped` and have both read it. The new predicate is a strict superset of the old `!hasSpacedRange` guard — `spacedRangePairs.every()` is vacuously true when no spaced range fired — so the over-cap channel's behaviour on every line without a spaced range is unchanged, and R2 firing on an endpoint the selector did not take still routes to the assertive channel. Exactly one input class changes routing: a clean fully-selected spaced range beside an unexamined over-cap token, which moves from `req-line-range-reading` to `req-line-unverified`. Pinned by `#3697-19n` (the twin of `#3697-19l` on the other side of the boundary — there a demonstrated drop outranks the unverified voice, here the cap outranks the ambiguous one), with `#3697-19o` as the negative control asserting a clean range with nothing over the cap is still a range reading. * docs(#3697): state the warning-code precedence, and what the cap condition actually is Two surfaces, one point. The round 7 finding cited CONTEXT.md's PHASE.REQ-LINE.SEAM.kinds predicate as the documentation of what `req-line-range-reading` claims, and it was right to: that predicate said "R2 alone fired on selected endpoints; nothing was dropped" with no mention of the scan cap, describing a line the code could not distinguish from one carrying a token it never examined. The range reading is the weakest of the three claims and yields to the other two: a demonstrated drop makes the line a misparse, and a token the cap left unclassified makes it unverified. `docs/CLI-TOOLS.md` gains that sentence; the CONTEXT.md predicate gains it plus two precision points that this round's own pre-push adversarial review extracted over three passes, each with a driven counterexample I reproduced before acting on it: * "nothing was dropped" overstates the rule. The discriminator is RULE-scoped by design (round 3, Major 3), so that a parenthesised ID-shaped token does not re-open the #2334 over-warning class — `(REQ-02)` is indistinguishable from `(ADR-7)` at token level and is carried by the skipped-text rider, never by this code. `REQ-01, (REQ-02), REQ-03 - REQ-05` selects three, names REQ-02 as skipped, and is still a range reading. The predicate now says "no rule named a dropped ID", which is what the code tests. * The deferral condition is `oversizedTokens` being non-empty, NOT the presence of a token past the cap. Those differ: a long token the selector itself took can be exempt, because selection is uncapped and anchored and such a token was therefore examined. `RANGE-01 - RANGE-05, R-<2047 sevens>` yields `oversizedTokens=[]` and stays a range reading. Two earlier attempts to characterise WHEN the exemption applies were both refuted — the neighbour test admits any non-short neighbour, not just a range operator — so the predicate now states the condition and defers the exemption's own rule to SEAM.cap rather than paraphrasing it a third time. Verified after the edit: deferral holds if and only if the cap left a token unclassified, across all three counterexamples plus controls, and an exempt selector-taken long token is exhibited. No behaviour change — predicate text, one CLI-reference paragraph, and the two regenerated indexes. Predicate count unchanged at 285 across 22 classes, 0 duplicate ids; lint-example-parser-parity and both `--check` generators pass. * test(#3697): rename the round 7 regression pair — 19n was already taken Self-found immediately after the push, before anything was published to the review thread. The two tests added this round were named `#3697-19n` and `#3697-19o`, and `#3697-19n` was already in use: it is the declared-blind-spot case for one-sided separators in both attachment directions, generated inside a loop with a computed label, which is why a grep for a literal `test('#3697-19n'` did not find it. The PR body's own *Declared blind spots* list already refers to `#3697-19n` with that meaning. Nothing failed. Duplicate test names do not error, and the suite stayed green at 567/567 — which is the argument for fixing it rather than against. Two concrete costs: any TAP name-set differential collapses same-named tests under `sort -u`, so one of the two becomes invisible to exactly the did-not-run and pass->fail checks that name-set comparison exists to perform; and a reviewer reading "#3697-19n" in the body now gets a different test than the one the body means. Renamed to `#3697-19p` (over-cap beside a clean range) and `#3697-19q` (its negative control), the next free ids in the series; the pre-existing `#3697-19n` is untouched at its original 4 occurrences. Cross-references inside the renamed block were updated with them. Negative control re-run under the new ids: 19p still fails against pre-fix source and passes after, 19q passes at both ends. --------- Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-09-01 14:36:57 -04:00
BeeHiggs	1a358ce0fd	feat(#2761): bracket-tolerant read path — roadmap/validate/verify/state recognize bracket ids (epic #612 PR-2) (#2867) ... * feat(#2761): gated heading-intro selection + one bracket identity grammar Foundation. Two owner-level changes plus a federated convention resolver; no reader consumes them yet. 1. GATED SELECTION, not an ungated widening. Widening every heading matcher requires the claim "no legacy ROADMAP contains a `[CODE.MM]` bracket followed by a digit", and that is false: `### [RFC.2119] 5:`, `### [v1.0] 2024:`, `### [ADR.612] 3:` and `### [ISO.8601] 2026:` are ordinary headings, and a widened reader claims each as a phase — moving phase_count and total_phases and adding W006 on projects that never opted in. No narrowing rescues it: the premise is about documents we do not control. `phaseHeadingPrefixSrcFor(baseline, convention, capturing?)` selects the pattern SOURCE at construction time. A project whose resolved `phase_id_convention` is not exactly 'bracket' compiles the same source string it compiled before. `baseline` is explicit because whether a site spells the any-bracket prefix or a bare `Phase\s+` is a fact about that site's history: handing the wider grammar to a bare site retro-grants tolerance it never had, in both directions — warnings appear, and a warning that fires today vanishes. Both bracket forms CAPTURE. `[GSD.999] Phase 07:` previously matched through the base alternative, which captures nothing, so a reader saw no bracket, fell back to the legacy token rule, and counted a labeled icebox heading while excluding the label-less one beside it — two derivations of one ROADMAP disagreeing. 2. ONE bracket identity grammar, one width rule. The milestone width is reconciled with the emit validator: pad2 output, so two digits or 3+ with no leading zero. Earlier spellings diverged in both directions — admitting `002`, which the validator rejects, and a bare `0` pad2 never produces — and the section recognizers accepted `[GSD.2]`, which SCOPED a milestone no phase heading could then resolve into, recreating the on-disk-count fallback this epic removes. An unpadded bracket is now uniformly malformed: it scopes nothing, bounds nothing, sections nothing. W005 on its directories is the surfacing signal. The milestone field is boundary-anchored, so a malformed run cannot match by its prefix (`GSD.002-01` read as sentinel `00`). Recognition stays case-insensitive because readers compile `/i`, but identity helpers match `[A-Z]`, so a captured id is folded first — otherwise `### [gsd.999] 07:` failed every sentinel test. The qualified key shares the width, the `(?=-|$)` boundary and the single-sub-phase shape of the directory token, because phaseTokenMatches returns unconditionally on a qualified hit: a key matching a directory isPhaseDirName rejects would be a final wrong answer. 3. resolvePhaseIdConvention federates workstream -> root exactly as config-loader does — including that root is a fallback only when a WORKSTREAM is active, so a project-scoped directory stands alone. loadConfig cannot serve this: it merges against CONFIG_DEFAULTS and drops keys it does not know, and this key is not among them. It governs the bracket-selection reads ONLY. PHASE_HEADING_PREFIX_SRC is left byte-identical: PR-1 shipped it, nothing consumes it, and it is superseded rather than redefined. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#2761): roadmap.cts selects its heading grammar from the convention Six matchers build their intro through the gated selector, and cmdRoadmapAnalyze / cmdRoadmapGetPhase / getRoadmapPhaseWithFallback each resolve the convention ONCE per command and thread it down. Three sites take the any-bracket baseline (they already tolerated `[anything] Phase N`); three take label-only (they spelled a bare `Phase\s+`). Handing the wider grammar to a label-only site retro-grants tolerance it never had — and not only by adding matches: on a legacy repo an unchecked `- [ ] **[v1.0] Phase 05: Thing**` bullet would start SUPPRESSING the W006 that fires today. Sentinel handling under bracket ADDS a rule rather than replacing one: a bracketed heading is a sentinel when its bracket milestone is reserved (`### [GSD.999] 01:`) OR when its token is, so the engine-wide 0/999 backlog convention keeps applying to `### [GSD.02] 999:`. Replacing the token rule let a mid-migration ROADMAP — bracket headings plus a legacy backlog block, exactly the content this epic targets — add entries to the progress denominator. The captured id is folded before the identity test, so a lowercase `### [gsd.999] 07:` is excluded too. The DIRECTORY read is threaded too. `cmdRoadmapAnalyze` resolves the convention once and hands it to all four of its heading/checklist patterns, but the single `phaseTokenMatches` call that decides `disk_status`, `plan_count`, `summary_count`, `has_context` and `has_research` was left two-argument — so every canonical `{CODE}.{MM}-{PP}-slug` directory read as `no_directory` with zero counts, on the PR's own headline verb, while the SAME build resolved those same directories correctly in three other places on the same repo (W006/W007 via phaseTokenFromDir, `state json` via the milestone filter, and the W021 milestone-complete read through this very helper's three-argument form). It failed ONLY for the directory shape the convention exists to name: a mid-migration bracket repo carrying legacy `01-one` dirs resolved fine, which is why nothing caught it. Measured, bracket vs its flat-legacy twin: `[["01","no_directory",0,0],["02","no_directory",0,0]]` against `[["01","complete",1,1],["02","planned",1,0]]`. The oracle is the twin, computed in the same test run, plus exact literals — `grep disk_status tests/adr-612-*` was zero hits before this, so neither the fix nor a future regression had any gate at all. Disclosed: a ROADMAP written in bracket form before config.json is switched reads as empty rather than mis-counted. Silent invisibility during the migration window is the deliberate trade against claiming phases on projects that never opted in. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#2761): validate.cts selects its grammar; gated directory recognition The W006/W007 feeders take the resolved convention as a threaded parameter. These sites carry the letter-tolerant `[\w][\w.-]*` capture, which makes them where an ungated widening does the most damage: `### [RFC.2119] 5:` enters roadmapPhases as a phantom and becomes a W007 "in ROADMAP.md but no directory on disk" on a project that never opted in. buildRoadmapPhaseVariants also surfaces the tokens borne ONLY by sentinel-bracket headings. Surfaced rather than filtered in place because roadmapPhases feeds both a membership check and a missing-directory warning, and only the latter should ignore an icebox item. That set is OCCURRENCE-AWARE, and the subtlety is load-bearing: roadmapPhases is a TOKEN set, so `[GSD.999] 01` and `[GSD.02] 01` collapse to one entry. Keying suppression on the token alone let an icebox heading silence a REAL phase that happens to share its number — a false negative strictly worse than the warning it removed. A token is suppressed only when no non-sentinel heading bears it. Directory recognition is added as gated FUNCTIONS beside the exported RegExp constants, which stay byte-identical: the `{CODE}.{MM}-` prefix is string-indistinguishable from the letter-prefixed-decimal family this repo documents as ambiguous, and folding a branch in changes those constants' answers on exactly that family. A RegExp constant has nowhere to attach a gate. The recognizer mirrors the emit grammar and delegates the token to the canonical owner, so recognizer and resolver agree on rejected input as well as accepted. Both functions throw on a non-string, matching the call pattern they replace. buildRoadmapPhaseVariants' CHECKLIST scan is capturing, like its heading twin and like the sibling checklist scan in roadmap.cts, and for the reason that one states: the bracket id has to ride along or the sentinel filter is blind to `- [ ] **[GSD.999] 01: Icebox**`. Left un-capturing, the scan called every checklist token REAL, and the occurrence-aware un-suppression loop then deleted the icebox token the HEADING scan had correctly marked sentinel — so `validate consistency` warned that a bracket ICEBOX phase had no directory, in the HOUSE ROADMAP shape where an icebox appears as both a bold bullet and a detail heading. `validate health` stayed silent on that same repo, so the two verbs disagreed — which is the disagreement `sentinelPhases` exists to close. Both directions are pinned, because the failure mode of a careless fix here is the opposite one: a real phase sharing a sentinel's token must still warn. It does, in all four shapes that attack it (sentinel heading + real bullet, lowercase sentinel, sentinel after the real heading, colon-less bullet). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2761): count bracket headings, and retire them, in both derivations Both `total_phases` derivations select their grammar from the resolved convention, in one commit — cmdStateSync already carries the comment that it mirrors buildStateFrontmatter "so both report consistent percents (#3242 Bug B)", so teaching one and not the other ships that divergence. The #1514 retirement filter widens WITH the counter it protects. The canonical gesture strikes the checklist BULLET and leaves the detail heading intact, so a bracket-form retirement went undetected and the phase stayed in the denominator forever. That is half a fix alone: the retired key is compared against phaseKeyFromDir, which called extractPhaseToken with no convention. Both halves land here. Under bracket the sentinel token rule composes as the full engine set {0, 999}, so this counter agrees with `roadmap analyze`, which has always excluded both — otherwise the two derivations report different numbers for one ROADMAP and the changeset's "excluded from every count" is false as written. The LEGACY path keeps its pre-existing 999-only rule: widening it there would move legacy totals, so the two stay split off the bracket path exactly as they are today. The sync-side assertion reads the PERCENT sync writes into the STATE.md body, not the frontmatter total_phases. Sync's own counter never reaches that field — the read derivation writes it — so asserting the frontmatter after a sync measures the read path twice and lets a mutation to the write-path guard survive. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#2761): verify.cts bracket-coherence W021 + selected milestone-complete read The shipped milestone-prefixed W021 gate keeps its ROOT-only config read, verbatim base semantics. Federating it silently moved a legacy convention's answer in BOTH directions on workstream repos — a W021 that fires at base vanishing, and one that is silent at base firing. resolvePhaseIdConvention governs the new bracket-selection reads only. B6, the milestone-complete check, keeps its ungated POSTURE (bug-557 pins it with an empty config) but selects its grammar from the convention. Inferring 'bracket' from the shape of a matched bracket ran a repo-failing check against a legacy ROADMAP that merely contained `### [RFC.2119] 5:`. Directory resolution widens with the heading read, so a bracket repo whose phases are on disk stays silent, and a bracket sentinel is not reported as unstarted. checkBracketCoherence is advisory and gated. Anchored to tokenizeHeadings so fenced examples cannot warn and heading level is structural. Its scope rules each close a way it silently did nothing or fired wrongly: only a genuine MILESTONE heading opens or closes a section (a `### Notes` used to reset scope and disable both sub-checks); a legacy `## v3.0` DOES close it; an M-NN or letter-suffixed phase heading raises missing-bracket and CONTINUES; a bare `#### 2026:` is not a phase; the full h2-h6 range is processed. Its section recognizer shares the one milestone width, so an unpadded `### [GSD.3] 05:` can no longer be a phase to the id grammar and a section to the section grammar at once, silently re-scoping every warning after it. validate consistency suppresses bracket sentinels in its missing-directory warning — the two verbs disagreed, health suppressing via notStartedPhases while consistency did not. The legacy reading is untouched, including its pre-existing wart that `### Phase 999:` still warns there. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2761): scope the milestone by its bracket; select the disk-side filter Two roadmap-parser reads, both of which made a bracket project's totals track the disk instead of the ROADMAP. The ADR pins the bracket milestone heading as `## [GSD.02] Foundation` — a name, no version — but scoping matched STATE's `milestone: v2.0` STRING against a heading, so the canonical form matched nothing and total_phases fell back to the directory count. The rule was re-derived in THREE places: extractCurrentMilestone plus two `milestoneBounded` guards; fixing one left the others falling back regardless, so they are now one gated helper. It matches the CANONICAL padded spelling only — accepting `0*N` bounded a milestone whose phases were invisible, which un-suppressed a progress percent computed off an unscoped disk count. getMilestonePhaseFilter's heading scan becomes the 14th selected read. On a bracket ROADMAP it collected nothing, so the filter degraded to pass-all and buildStateFrontmatter counted every other milestone's directories — making the bracket convention strictly worse than the M-NN one it supersedes on the property that matters most: totals must track the ROADMAP, not the disk. The DIRECTORY side of that same filter is selected with it. Teaching only the heading scan was half a fix and a worse one: `milestonePhaseNums` became non-empty, so the pass-all degrade stopped firing, but no bracket directory could satisfy the three legacy dir checks (numericRe fails on `GSD.02-05-five`, the custom-id match captures the project code `GSD`, and stripProjectCodePrefix does not strip a dotted prefix). Every bracket directory was rejected, and completed_phases / total_plans / completed_plans / percent all collapsed to 0 while `state sync` went on writing a percent off the unfiltered disk — `state json` reporting 0% on the same repo, in the same second, that STATE.md's body called 67%. That is the #3242 Bug B divergence this PR exists to avoid, and total_phases could not show it: `Math.max(phaseDirs.length, roadmapPhaseCount)` floors it at the ROADMAP count no matter how many directories are rejected. The dir side matches on the milestone-QUALIFIED id, delegated to the owner's gated `phaseTokenMatches(dir, id, 'bracket')`, not on the bare token: READING-B puts the milestone in the bracket, so `GSD.01-01-old-one` and `GSD.02-01-one` share the token `01` and only the qualified key separates them. The qualified ids are kept in their own set — a hyphen in `milestonePhaseNums` would flip `roadmapUsesHyphenedIds` and silently move the LEGACY dir path on a bracket repo — and the branch is ADDITIVE: on a miss it falls through to the three legacy checks, so a bracket project carrying legacy-shaped directories reads unchanged. Both are resolved lazily and gated, so the legacy path pays neither a config read nor a second scan and cannot change answer. The scoping call is also GUARDED: resolvePhaseIdConvention reaches planningDir, which throws a plain Error for a GSD_PROJECT/GSD_WORKSTREAM segment carrying `/`, `\` or `..`. At base the only planningDir call in extractCurrentMilestone sits inside the STATE-read try, so the function returned normally on such an environment; an unguarded one here let that escape and broke the never-throws invariant that getRoadmapPhaseInternal and getMilestoneInfo three hundred lines below carry #2245 / ADR-227 notes about. Unreachable through the CLI — GSD_WORKSTREAM is rejected up front by the workstream-name policy and GSD_PROJECT throws identically at base — but reachable by any in-process embedder, which is precisely who that invariant is for. The filter's own resolve call was already inside its try and is unaffected. The milestone-qualified key is formed only for a token that is itself a bracket phase token. `${bracketId}-${token}` is a string SPLICE, so a mid-migration heading carrying an M-NN label — `### [GSD.02] Phase 02-01:` — spliced to `GSD.02-02-01`, which the qualified-key grammar reads as milestone 02 / phase 02: the `-01` truncated, both such headings collapsing to one key, and the heading claiming `GSD.02-02-two`, the directory it does NOT name, while rejecting `GSD.02-01-one`, the one it does. The guard drops those headings back to the unqualified legacy path, restoring the base ACCEPTANCE VECTOR exactly — pinned against the milestone-prefixed reading of the same ROADMAP, which is base-identical on this shape. Scoped precisely, because the fixture moves one number that the guard does not touch: `total_phases` on it reads 1 at base and 2 here. That is the bracket heading COUNT this PR exists to add, not the splice — measured identical with and without the guard, and identical to what the canonical `### [GSD.02] 01:` spelling does on the same fixture (both read 2 with zero directories on disk, where base reads 0). The claim is base-equivalent ACCEPTANCE, not a base-equivalent reading. One consequence is stated rather than fixed: a heading whose token carries a hyphen still puts that hyphen into milestonePhaseNums and so still flips `roadmapUsesHyphenedIds`. Base does the same for that spelling, so preserving it is what keeps the shape base-equivalent; excluding the token would have moved answers versus base on malformed input. The comment at the qualified-set declaration is corrected to claim only what is true — it keeps QUALIFIED IDS out of that flag's input, not hyphens in general. The oracles ship with it, and they are the five numbers, not the one: the parity gate now asserts total_phases, completed_phases, total_plans, completed_plans AND percent, on both derivations, on two fixture shapes (one milestone; two milestones with stale prior-milestone directories on disk). The oracle is the flat-legacy twin, built in the same test run and compared number for number, plus exact literals so a shared wrong answer cannot pass. The oracle SUBSTITUTION is itself pinned. The M-NN spelling of these shapes could not serve, because buildStateFrontmatter's #2445 de-dup key captures only a directory's leading integer and collapses `02-01-one` / `02-02-two` / `02-03-three` to one — measured [3,0,1,0,0] against the flat-legacy twin's [3,2,3,2,67], identically at base and before this fix, and structurally unreachable from the bracket key space. That reasoning is only sound while it stays true, so a characterization test holds the M-NN reading down on the two numbers that do not depend on which directory wins the mtime race. Widen the de-dup key and it fails, instead of quietly invalidating the changeset's disclosure. Also adds the call-site pin. The structural table pins transcription against the selector; it cannot see a call site whose BASELINE ARGUMENT is wrong. Flipping verify.cts's milestone-complete site to the wider baseline grants a fires-on-every-repo check tolerance it has never had, and every behavioural test still passed. The pin reads the shipped sources and asserts the mode at each of the 14 sites, count-exact. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2761): pin the bracket read surfaces in the parity gate This gate exists because #2043 fixed one bug across five hand-edited copies of a rule and #2232 was the residual that survived, because a later reader could not tell the copies were one rule. PR-2 adds two consumers, so they belong here. Surface 7 — the heading read and the directory read must agree about WHICH phase a `MM-<seg>` pair names, across the shared width corpus, and the bracket and legacy spellings of one heading must yield the same token. Surface 8 — the two bracket directory readers, in BOTH directions. Agreement on ACCEPTED input was already pinned; agreement on REJECTED input is where they actually diverged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#2761): changeset Disclosures for the PR body (deliberate, not defects): - phase_id_convention is not a CONFIG_DEFAULTS key, so loadConfig drops it and cannot serve as the convention resolver however the file is federated. This PR ships its own workstream->root resolver; adding the key and its value enum is later-slice work. - Convention matching is strictly === 'bracket'. A misspelled value reads as not-configured and the project keeps legacy behaviour silently. - An UNPADDED bracket milestone (`[GSD.2]`) is malformed: it scopes nothing, bounds nothing, sections nothing, and is not a phase id. W005 on its directories is the surfacing signal. - WIDTH UNIFICATION MOVED FOUR MERGED PR-1 EXPORT ANSWERS on non-canonical inputs, none of which toDir can emit and none of which had a bracket caller at base: isSentinelPhaseId('GSD.0-01', 'bracket') true -> false isSentinelPhaseId('GSD.0999-01', 'bracket') true -> false getMilestoneFromPhaseId('GSD.2-01', 'bracket') 'v2.0' -> null getMilestoneFromPhaseId('GSD.002-01', 'bracket') 'v2.0' -> null The canonical pad2 sentinel spelling `[GSD.00]` still tests true. - FLAG TO MAINTAINER: docs/adr/612:132 reads "Sentinel behavior (0.x / 999.x -> milestone null) is preserved". After the unification that holds for the canonical `00` spelling only, not for a bare `[GSD.0]`. ADR wording is yours; flagging the tension rather than editing it. - The bracket sentinel rule COMPOSES with the legacy one — a bracketed heading is a sentinel when its bracket milestone OR its token is reserved. Under bracket the state-side token rule is the full {0, 999} set so both derivations agree; the LEGACY path keeps its pre-existing 999-only rule, unchanged. - validate consistency's legacy reading is untouched, including the pre-existing wart that `### Phase 999:` warns there while validate health suppresses it. - find-phase still cannot resolve a bracket phase directory. phase-locator.cts is outside this PR's module set. Sibling PR #2559's matchPhaseDirs calls phaseTokenMatches without a convention, so whichever slice lands second must thread it through. - Four of the five bracket readers scan raw ROADMAP content, so a bracket heading inside a fenced code block is read as a phase. Pre-existing for the legacy spelling; parity, not a new class. - roadmapPhaseLookupSources gained no bracket source: nothing emits a milestone-qualified query into it yet. - roadmap validate remains a separate, unfederated convention reader. Pre-existing and base-identical, but two verbs can disagree about the active convention on one project. - _diskScanCache keys on cwd while the values it caches are now convention-dependent. Not reproducible through the CLI; pre-existing for the workstream dimension, widened here. Stated as inconclusive. - A ROADMAP written in bracket form before config.json is switched reads as empty rather than mis-counted — the deliberate migration-window trade. - THE READ AND WRITE PERCENTS STILL DIVERGE ON A MULTI-MILESTONE REPO, and that divergence is MIRRORED under bracket rather than closed. buildStateFrontmatter applies the milestone filter; cmdStateSync does its own fs.readdirSync and never calls it, so on a repo carrying prior-milestone directories the read path reports the SCOPED percent and the sync body reports the WHOLE-DISK one. Measured on the true base build (d04592de), flat-legacy spelling, 3 in-scope phases with 1 complete plus 2 stale prior-milestone dirs: `state json` [3,1,3,1,33], sync body 60%. The bracket twin of that repo now reads the same two numbers — 33 and 60. Scoping the sync counter would move every legacy repo's percent, which a bracket read-path PR must not do. The gate pins both sides, so the mirror cannot silently become a one-sided fix. - THE PARITY ORACLE IS THE FLAT-LEGACY TWIN, NOT THE M-NN ONE, and that is a measurement finding rather than a preference. buildStateFrontmatter's #2445 de-dup key captures only a directory's LEADING integer, so the M-NN dirs `02-01-one` / `02-02-two` / `02-03-three` all key to `2` and two of the three are dropped before they are ever counted: base reads [3,0,1,0,0] where the flat-legacy twin of the same repo reads [3,2,3,2,67]. Present identically at base and at HEAD, untouched here, and structurally unreachable from the bracket key space — `GSD.02-01-one` does not match that pattern at all, so every bracket directory keys to its own name. The source line already carries a `phase-id-owner:` sanction recording the divergence. Mirroring it under bracket would mean manufacturing a collision that cannot occur, so the gate compares against the flat-legacy spelling, which is uncontaminated. This paragraph is itself pinned: a characterization test holds the M-NN reading on the two numbers that do not depend on which directory wins the mtime race, so widening the de-dup key in a later slice fails the suite rather than silently making this disclosure false. - THE `phaseTokenMatches` CALL-SITE CENSUS, stated so the remaining gaps are auditable rather than implied. 13 call sites outside the owner (phase-id.cts). THREE are three-argument: verify.cts:2229 (the W021 milestone-complete read, already was), roadmap.cts:436 (`roadmap analyze`'s directory lookup, threaded by this PR) and roadmap-parser.cts:792 (the disk-side milestone filter, added by this PR). The other TEN are two-argument and stay that way — phase.cts ×5 (220, 277, 444, 585, 1547), phase-locator.cts:62, smart-entry.cts:243, init.cts:1414, milestone.cts:551 and verify.cts:2467. All ten are untouched by this PR and base-identical. One of them sits in a file this PR DOES edit, so it is named rather than left to a reader's grep: verify.cts:2467, `verify schema-drift <phase>`. Measured on a bracket repo across base / pre-fix branch / this HEAD, all three agree on all three argument forms — `verify schema-drift GSD.02-01` and `… 01` both report "Phase directory not found" on every build, and `… GSD.02-01-one` resolves on every build through the exact-directory-name fallback. So the user-visible shape of what stays broken is: a bracket phase is addressable there by full directory name only, exactly as at base. Threading the convention into a function this PR never touched, in the last round before ship, is the wrong trade; it is where the same one-argument fix goes next, alongside milestone.cts:551 and init.cts:1414. - A BRACKET HEADING WHOSE TOKEN CARRIES A HYPHEN (`### [GSD.02] Phase 02-01:`, a mid-migration spelling) forms NO milestone-qualified key, and therefore scopes through the unqualified legacy path — base-equivalent ACCEPTANCE, which is the claim, and not a base-equivalent reading: `total_phases` on that shape moves 1 -> 2 for the same reason it moves on the canonical `### [GSD.02] 01:` spelling, because counting bracket headings is what this PR does. Such a token still flips `roadmapUsesHyphenedIds`, as it also does at base. The comment at the qualified-set declaration now claims only that narrower, true thing. The `pr:` field carries the sub-issue number as a placeholder — it must be updated to the real PR number when the PR is opened. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#2761): point the changeset at PR #2867 * test(#2761): fast-check properties for the convention-selection layer CONTRIBUTING.md mandates a generative property test for parser/bijective-contract changes; PR-2 shipped six example-based files and none. This adds the missing layer, scoped to what PR-2 actually contracts — WHICH pattern each reader compiles, decided by the resolved `phase_id_convention` — rather than restating PR-1's grammar round-trip properties, which already live in tests/adr-612-bracket-grammar.test.cjs. Four properties: P1 an opted-in repo reads the ADR-canonical label-less bracket heading/dir and a non-opted-in repo is byte-blind to the identical input; P2 every non-bracket convention agrees with the hand-transcribed BASE source over generated content, including bracket-DOTTED legacy prose (`[RFC.2119] 5:`) that must never be claimed as a phase; P3 nine per-field mutations are rejected and the one case variation folds instead; P4 both sides of a phase comparison derive the same key under the same convention. Generators template every input from raw primitives — nothing is seeded through renderPhaseId/toDir, the p2() tautology that made #2258 round 1's property test structurally unable to find B1. Domain reaches past 99 into the 3+-digit branch (round 2's numArb-capped-at-99 miss), forces sub-phases in at weight, and pins both sentinel milestones. Falsified against the COMPILED lib, not the source: five deliberate mutants (gate never fires; gate always fires; milestone width widened to \d+; the #612 convention forwarding dropped from phaseKeyFromDir; extractPhaseToken's bracket branch ungated) each fail the specific property that should catch them — 16/2, 16/2, 15/3, 17/1, 17/1 pass/fail — and the lib restores byte-identical. An earlier draft of P2 held vacuously: its base regex omitted the markdown furniture the selected one carried, so every realistic `### Phase NN:` line matched neither side. The gate-always-fires mutant did not kill it. Both are now compiled through one function, and that mutant kills P2. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2761): adversarial malformed bracket tokens across the tolerant readers The existing boundary coverage stopped at shapes the emit grammar rejects (unpadded `[GSD.3]`, wrong-case, `12A`). It never exercised a STRUCTURALLY broken token — a non-numeric milestone, a bracket that never closes, a bracket nested in another — which is the input a tolerant reader is most likely to half-read, and the one the PR's own regex commentary is explicit about. read-tolerance (roadmap heading scan + validate's dir and variant builders): ten malformed headings, each asserted to be read as a phase by NO convention and to give the opted-in repo the same answer as the legacy one; the corpus driven through `roadmap analyze` end to end; malformed DIRECTORY names asserted unrecognized and non-throwing on all four conventions; and the two variant builders asserted to agree, since a widening that reaches only one splits `validate consistency` from `validate health` (the #3242 Bug B shape). coherence (verify.cts W021): the same six broken shapes asserted to raise no W021 of their own AND not to re-scope the W021 that follows them — the G2 failure mode reached from a different shape, where a heading that is not a phase but IS read as a section silently moves later warnings onto the wrong milestone. Both files gain a pathological-input time bound. Nested quantifiers over a long unclosed bracket are the classic ReDoS shape and two commits on next (#2828, #2944) were CodeQL-flagged for exactly that, so the bound is asserted rather than argued from reading the pattern. The probes themselves parse no regex. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2761): document "bracket" as a phase_id_convention value The row listed only `"milestone-prefixed"` and `null`, so after two shipped slices (#2258 grammar, this PR's read path) the convention had no documented enum value. CONFIGURATION.md is also a top-10 historical co-changer of both src/verify.cts and src/state.cts and was absent from this PR. The row states the boundary rather than the ambition: `"bracket"` changes the READ path only, there is no migrator and no emit yet, and a project on any other value compiles the patterns it compiled before. That keeps the docs honest for the two releases before PR-3 and PR-4 land, instead of describing a convention a user cannot yet migrate to. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#2761): retype the changeset Added, drop the docs-exempt marker `Fixed` was wrong by CONTRIBUTING.md's own definition — a fix restores documented behavior, and bracket read tolerance is the second slice of a capability that did not exist before #2258. The type also carried a `docs-exempt` marker, and `Fixed`/`Security` are exempt from the docs-required lint, so the typing had the effect of routing around a gate this change should pass. It now passes it: `lint-docs-required` returns ok_docs_updated on the CONFIGURATION.md row added in the previous commit. Body gains one sentence pointing at that row and restating that `"bracket"` is a read-path opt-in until the migrator and write path land. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2761): pin the version-less bracket milestone scoping gap; narrow the claim The changeset asserted that milestone scoping "recognises the ADR-canonical `## [GSD.02] Foundation` heading and applies to the phase DIRECTORIES too." A CLI probe on that exact heading form falsifies the second half: with no `vN.N` in the milestone heading the directory side does not scope, and directories from BOTH the prior and the later milestone are admitted. Measured 4 dirs counted where the milestone declares 2. Every bracket fixture in the suite writes `## [GSD.02] v2.0: …`, so nothing covered the form the ADR actually specifies — and the state.cts doc comment calls that version-less form canonical. Mechanism, in extractCurrentMilestone: the bracket scope branch selects the right currentSection, but `preambleCutoff` keys off a pattern requiring a version or status emoji, so a version-less roadmap falls back to the current milestone's own offset and every PRIOR milestone lands in the preamble — whose phase-stripping regex only strips `Phase N:`-labelled headings, so bracket phase headings survive it. Independently, `computeSectionEnd` accepts a boundary only on a version/emoji heading, so the section runs to EOF and every LATER milestone is swept in. Two sites, bidirectional. Not fixed here: it changes milestone scoping, which is shared with the legacy path. Five characterization tests pin today's reading plus a versioned CONTROL proving the version string is the only difference, and the changeset sentence is narrowed to what the code does. The DEFECT assertions are written to be INVERTED by the fix, not deleted — that inversion is its regression proof. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2761): re-anchor the branch's own cross-file line citations after the rebase Three of this branch's code comments cite sibling call sites by line number, and the rebase onto 178ec000 moved two of the three targets: roadmap-parser.cts validate.cts:210 -> :218 (const g = capturing ? 1 : 0) state.cts:1715 -> :1752 (const bg = … 'bracket' ? 1 : 0) roadmap.cts verify.cts:2229 -> :2355 (phaseTokenMatches 3-arg form) `state.cts:1715` had drifted 37 lines and now lands on the retirement skip, not the capture-offset idiom the sentence is about — the citation read as evidence for a claim the cited line does not support. planning-workspace.cts's `config-loader.cts:618/:649` was checked and is still correct; left alone. Comment-only. Build, drift guard and the bracket suites re-run unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2761): scope the version-less bracket milestone heading too (B1) computeSectionEnd and the preambleCutoff scan in extractCurrentMilestone (roadmap-parser.cts) only recognized a milestone boundary heading that carried a vN.N token or a status emoji. The ADR-canonical bracket heading (## [GSD.02] Foundation) carries neither, so on that shape computeSectionEnd fell through to content.length (sweeping every LATER milestone into scope) and preambleCutoff fell back to the current milestone's own offset (leaking every PRIOR milestone's bracket phases into the preamble, whose Phase-N: strip regex never matches them). Under the bracket scope branch, both sites now also accept a `#{1,2}\s+\[CODE.MM\]` boundary, built from phase-id.cts's BRACKET_ID_SRC (single owner of the bracket-id grammar) rather than a re-typed literal. `#{1,2}` is the deliberate discriminator: a bracket PHASE heading is level 3 and shares the same `[CODE.MM]` prefix, so a `#{1,3}` boundary would swallow it too. Reachable only when bracketScopeConvention === 'bracket' was already resolved (i.e. the bracket scope branch actually fired), so version-bearing/emoji headings and non-bracket conventions take the exact pre-existing code path byte-identically — confirmed by the full adr-612 suite staying green. Inverts the four DEFECT assertions in the "#612 PR-2 CHARACTERIZATION: a version-less bracket milestone does not scope" describe block (tests/adr-612-bracket-phase-counting.test.cjs) into their regression-proof form, per the block's own doc comment, and reframes the describe title/comments accordingly. Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which described the directory-side version-less gap as an open, un-closed bound. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): thread sentinelPhases into validate health's W006 loop (B2) cmdValidateHealth's W006 loop (src/verify.cts) destructured only roadmapPhases from buildRoadmapPhaseVariants, not sentinelPhases — unlike cmdValidateConsistency, which already skips sentinelPhases with the identical guard a few hundred lines up. A heading-only bracket icebox/pre-milestone entry ([GSD.999] / [GSD.00]) therefore gained a false W006 "no directory on disk" from validate health while validate consistency correctly stayed silent on the very same ROADMAP — the two validators contradicting each other. Threads sentinelPhases through and skips it before the existsOnDisk check, mirroring the consistency guard exactly. Gated the same way sentinelPhases already is (empty unless phase_id_convention is 'bracket'), so a legacy repo's W006 reading — including its own pre-existing wart where a legacy `### Phase 999:` still warns on both verbs — is untouched; confirmed by the existing "INHERITED WART, unchanged" test staying green. Adds the paired-agreement regression test (#612 PR-2 B2 describe block in tests/adr-612-bracket-read-tolerance.test.cjs): a sentinel-only bracket roadmap must produce no missing-directory warning from EITHER validator, plus a CONTROL proving a real phase with no directory still warns on both. Confirmed red (health false-W006) against the pre-fix code before applying the fix. Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which described the asymmetry as already closed and in the wrong direction (it credited validate health with already staying silent, when health was the one falsely warning). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#2761): pin mixed-shape preamble cutoff and boundary heading levels Closes two self-flagged coverage gaps in the B1 fix (commit 08d5b0c4) ahead of adversarial review. No src change — all three new tests are green against the code as committed. 1. earliest-of-either preambleCutoff comparison: only exercised where the version/emoji match and the bracket match happen to land on the same heading. Adds the mid-migration mixed shape (version-bearing PRIOR + version-less CURRENT) and asserts scoping outcomes (accepts booleans + total_phases), not internals. 2. `h.level <= 2` conjunct in computeSectionEnd: provably redundant whenever the selected milestone heading is level 2 (every existing fixture), since `h.level > level` alone already implies it there — a mutant deleting the conjunct would have survived every prior test in this file. Adds a level-3 CURRENT-heading fixture (with a real PRIOR milestone so the preamble side-channel can't independently rescue the truncated phases) that makes the conjunct's deletion test-visible, confirmed by hand-mutating a throwaway copy of the compiled output (never touching tracked src or the real build) and observing the assertion flip. Also pins a level-1 companion case (#{1,2} tolerance, not just level 2). NOT included here: the other mixed-shape direction (version-less PRIOR + version-bearing CURRENT) turned out to be a genuine, currently-unfixed gap — reported separately rather than silently patched or weakened, per instruction not to touch src while a probe run is in flight. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): engage bracket boundaries when the current milestone heading is version-bearing (B3, self-caught) Found during round-2 self-verification of B1 (commit 08d5b0c4), while closing the mixed-heading-shape coverage gaps flagged in my own review notes. The B1 fix resolved `bracketScopeConvention` only inside the `if (headingMatches.length === 0)` gate that also drives SELECTION's own bracket fallback (which heading counts as "current"). That gate is correct for selection, but `bracketScopeConvention` also feeds computeSectionEnd's and preambleCutoff's boundary detection further down — which accidentally inherited selection's gate instead of having its own. Trigger shape: the CURRENT milestone heading is itself version-bearing (`## [GSD.02] v2.0: Current Milestone`), so the primary version-string match succeeds immediately — headingMatches.length !== 0 from the very first check — and the entire bracket-resolution branch was skipped. A sibling milestone (PRIOR or LATER) that is version-less then got neither the version/emoji boundary rule (it has none) nor the bracket boundary rule (never resolved), reproducing the original #612 defect (total_phases falling back to the whole-disk count) through a structural shape B1's own fixtures never exercised — every one of them is uniformly version-bearing or uniformly version-less across all three milestones, never mixed with CURRENT specifically being the version-bearing one. Fix: resolve `bracketScopeConvention` unconditionally, decoupled from `headingMatches.length`. SELECTION is deliberately left untouched — the `if (headingMatches.length === 0 && bracketScopeConvention === 'bracket')` fallback that picks which heading is "current" keeps its original gate byte-for-byte (confirmed by diff: that line is unmodified). Only the convention *resolution* moved out from behind it, so boundary detection can consult it regardless of which branch selected the heading. The extra `resolvePhaseIdConvention` call this now costs on every invocation (previously paid only when the version match found nothing) is the accepted cost: a non-bracket repo still resolves to something other than 'bracket' (or null on a poisoned env, caught exactly as before), so `bracketMilestoneHeadingRe` stays null and every downstream branch is byte-identical to today — confirmed by the full adr-612 + roadmap-parser + state + verify + health-validation suite staying green (1260/1260) and the all-version-bearing/legacy fixtures showing no behavior change. TDD: tests/adr-612-bracket-phase-counting.test.cjs describe block "#612 PR-2 B3: bracket boundaries engage even when CURRENT is version-bearing but a sibling is not" — 4 tests, confirmed red against pre-fix code (leak-in booleans true/true, total_phases 4) before this change, green after. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): reject same-milestone continuation headings as boundaries (B1) Gate-2 adversarial review Blocker 1: the B1/B3 boundary fired on ANY as the one currently selected — a version-less checklist/detail split (`## [GSD.02] Foundation (Phase Details)`, or an ad-hoc continuation heading) truncated the current milestone's own section instead of being recognised as a continuation of it. The `(Phase Details)` re-append only searches VERSION-STRING matches, so a version-less continuation heading was cut out and never re-appended — a confidently wrong, non-degraded phase count for a still-incomplete milestone (repro8 case 1: 1/1/100 instead of 2/1/50; repro5: same, on a fully version-less roadmap with no sibling milestones at all). Introduces one shared helper, isBracketMilestoneBoundary(headingText, level, selectedBracketId), used by both computeSectionEnd and the preambleCutoff bracket scan, replacing the ungated `h.level <= 2 && bracketMilestoneHeadingRe.test(...)` inline check. `selectedBracketId` (case-folded via phase-id.cts's foldBracketId, matching the branch's own fold-before-identity convention) is derived from `selected[0]`, which is the full matched heading line on BOTH selection paths (version-string and bracket-fallback), so one extraction covers both. Level cap stays at `level > 2` for now (temporary — ADR-612's content discriminator replaces it in the next commit); same-milestone rejection is the change this commit is scoped to. DEVIATION from the reviewed plan, caught empirically: applying the same-milestone rejection at the preambleCutoff site (as literally specified) regressed an existing pin ("boundary heading level: a level-1 CURRENT milestone heading also scopes correctly") and a fenced-heading case (repro10 A3) — because preambleCutoff's job is "where does the earliest milestone-shaped heading sit, scanning from the TOP of the document," and the selected heading's own occurrence is always a correct answer to that question regardless of same-id-ness; rejecting it let the earliest-of-either comparison fall through to a stray LATER heading instead. `selectedBracketId` is threaded through as `null` at the preambleCutoff call site for this reason — bracket-shaped (and, from the next commit, phase-tail) discrimination still applies uniformly at both sites; only the same-milestone component is call-site-specific, since it encodes a "keep scanning past this heading" instruction with no counterpart in a top-of-document search. Tests: new describe block "#612 PR-2 B1 round-2: a same-milestone continuation heading is not a boundary" — RED-turned-GREEN fixtures for repro8 case 1 and repro5, plus PINs for repro8 case 3 (trailing different-id icebox still terminates) and repro10 A1 (all-version- bearing + icebox + Phase Details stays exactly 2/1/50 — no double-count from the same-milestone exclusion interacting with the pre-existing detailsMatch re-append). syncedTotal()/syncedPercent() assertions omitted from the repro10 A1 pin: that fixture carries dirs outside the current milestone, which exposes the SEPARATE Major 1 defect (cmdStateSync's body percent from an unfiltered disk scan) — asserted once Major 1 is fixed, not here. Full suite green (796/796 across the targeted adr-612 + roadmap-parser + state files); node scripts/lint-phase-id-drift.cjs clean; eslint clean on both changed files. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): bracket boundary discriminates by content, not heading level (B2) Gate-2 adversarial review Blocker 2: three sites disagreed about which heading levels are a bracket milestone. The selector (roadmap-parser.cts's bracket-fallback SELECTION branch, `^#{1,3}\s+\[CODE.MM\]`) and `isMilestoneBounded` (state.cts) both admit level 1-3, but isBracketMilestoneBoundary's level cap only admitted level 1-2 (`h.level <= 2`, from the B1 commit). A `###`-level bracket milestone heading was therefore SELECTED and BOUNDED but never TERMINATED: computeSectionEnd ran with level=3, a level-3 SIBLING milestone survived the pre-existing `h.level > level` (not-deeper) filter, failed the version/emoji test (version-less), then failed `h.level <= 2` — falling through to `return content.length` and sweeping the sibling milestone's own phases into the current one. Reproduces trek-e's original #612 defect verbatim ("a safe degrade became a confidently-wrong persisted number") on a heading level the selector and bounding predicate both already admit (repro2 case C: 4/75% instead of 2/100%; mechanism confirmed directly via repro7 — extractCurrentMilestone returned the whole 214-byte document). ADR-612 Decision 1 (docs/adr/612-bracket-phase-id-convention.md:56) specifies the discriminator as CONTENT, not level: "a phase heading is a bracket followed by a digit-then-colon ([GSD.02] 05:); a milestone heading is a bracket followed by a name." Replaces the `level > 2` rejection with BRACKET_PHASE_TAIL_RE — built by interpolating phase-id.cts's single-owner phaseHeadingPrefixSrcFor(ANY_BRACKET, 'bracket', false) plus the digit + optional-tag + colon tail every phase-heading counter in this file already spells, not a re-typed grammar — and widens the level check to a depth-sanity cap of 3 (mirroring the selector's own `#{1,3}` ceiling; NOT itself a phase/milestone discriminator). Covers the dotted sub-phase heading form (`[GSD.02] 05.03:`) via the same `[\w][\w.-]*` token, pinned by a new fixture — the shape where a regex slip in the tail grammar would hide. preambleCutoff's own raw-scan regex is widened from `^(#{1,2})` to `^(#{1,3})` in lockstep: the outer pattern's level ceiling must track the helper's cap, or a level-3 PRIOR milestone heading is invisible to that scan and its own phase heading leaks into the preamble un-stripped (a real double-count this widening closes, verified against repro2 case C directly). The existing "boundary heading level: a level-3 CURRENT milestone heading still scopes correctly" pin (3e562f12) now passes via a DIFFERENT mechanism than before — its own neighbours are version- bearing, so it previously passed via the version/emoji rule (the level cap was never actually exercised by that fixture, per the round-2 review's own finding); with the content discriminator, the SAME fixture's level-3 phase headings are now correctly excluded because they are phase-tail-shaped, not because they are too deep. A deliberate mechanism change, confirmed by re-running that test green after this commit. Also updates the "every selector call site declares the right baseline" governance pin (adr-612-bracket-heading-selection.test.cjs): BRACKET_PHASE_TAIL_RE is a new, legitimate ANY_BRACKET call site in roadmap-parser.cts (always passing the literal 'bracket' convention, since its only caller is already gated on bracketBoundaryActive) — EXPECTED count bumped 1->2, with a matching BASE_SITES transcription entry (identical src to every other ANY_BRACKET site, since the function is pure). Tests: new describe block "#612 PR-2 B2 round-2: the bracket boundary is a CONTENT discriminator, not a level cap" — RED-turned-GREEN for repro2 case C (exact total AND truthful percent, since isMilestoneBounded already returns true at #{1,3}) and repro7's mechanism, a PIN for the dotted sub-phase form, and a re-pin of repro8 case 3 (icebox) under the new mechanism.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): fence-aware preamble cutoff on the bracket branch (Blocker 3) Gate-2 adversarial review Blocker 3: preambleCutoff's bracket scan used a raw content.match/matchAll — blind to fenced code blocks — while its sibling computeSectionEnd (a few lines above it) already consumed tokenizeHeadings(content), which strips fences. The two halves of one boundary semantic disagreed about what a heading is. A fenced markdown example in the preamble containing a bracket heading (ADR-612's own docs do exactly this) was textually the earliest `#{1,3} [CODE.MM]` match: preambleCutoff landed INSIDE the fence, `preamble = content.slice(0, preambleCutoff)` ended with an unclosed opener, and the unbalanced fence then blinded getMilestonePhaseFilter's own tokenizeHeadings(scope) call — every heading in the returned scope vanished, phaseCount degraded to 0, and the pass-all filter admitted every directory on disk (repro11's mechanism, confirmed directly: fence count 1/odd, tokenizeHeadings(scope) -> only "Roadmap"). Regression vs round-1, which had no bracket pattern to blind and so fell back to the correct heading (repro12 bracket row: 2/1/50 at round-1, 4/3/75 at HEAD). Fixed by hoisting one tokenizeHeadings(content) call (currentMilestoneHeadings) shared by computeSectionEnd and the preambleCutoff scan, which now iterates that same fence-aware token list instead of a raw regex. HeadingToken.text is already hash-stripped and trimmed, so isBracketMilestoneBoundary needs no `^#{1,3}\s+` re-derivation at this site (that spelling would not match h.text — a note the round-2 review called out explicitly, confirmed while porting). selectedBracketId stays `null` here, unchanged from the B1 commit's same-milestone-exclusion reasoning. DISCLOSED, not fixed (explicitly out of scope per the round-2 review's own minimal-fix note): the LEGACY (non-bracket) anyMilestonePattern raw-match path shares the identical fence-blindness hazard and stays byte-identical — a bracket repo whose preamble has a fenced VERSION-BEARING heading still has the legacy raw-match win the earliest-of-either min() (repro12's LEGACY control: 4/3/75, unchanged across base/round-1/HEAD/this commit). Pinned here so a future reviewer files this as a known, pre-existing gap rather than a new regression. Tests: new describe block "#612 PR-2 Blocker 3 round-2: preambleCutoff is fence-aware (bracket branch only)" — RED-turned-GREEN for repro12's bracket row and repro11's mechanism (fence balance + non-degraded phaseCount + correct per-directory admission), a PIN for repro12's LEGACY control (the disclosed gap, explicitly unchanged), and a PIN for repro10 A3 (a fenced heading INSIDE the current section must still not terminate it).

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): scope cmdStateSync's disk scan by milestone under bracket (Major 1) Gate-2 adversarial review Major 1: `state sync` wrote a Progress PERCENT computed from an UNFILTERED whole-disk scan, beside the milestone-scoped total_phases/completed_phases it writes into the same STATE.md via the refreshed frontmatter (syncStateFrontmatter -> buildStateFrontmatter, which has always applied getMilestonePhaseFilter for the READ path). cmdStateSync's own `fs.readdirSync` chain (the WRITE-path scan) never called the milestone filter at all, unlike buildStateFrontmatter's identical-purpose scan. One command therefore wrote two contradictory numbers into one file: on the ADR-canonical version-less bracket fixture (4 dirs, 3 complete; asserted milestone = 2 phases, both complete), base wrote total_phases:2/completed_phases:2 (correct, from the READ derivation) alongside body Progress 75% (wrong — from the unfiltered WRITE derivation; repro3). Fixed by threading `getMilestonePhaseFilter(cwd)` through the same `.filter()` chain buildStateFrontmatter already applies, gated on `syncConvention === 'bracket'` (falling back to a pass-all predicate otherwise) — so totalDiskPlans/totalDiskSummaries/diskCompletedPhases/ syncTotalPhases become milestone-scoped under bracket, byte-identical under legacy. DEVIATION (approved, stated plainly): an earlier phrasing of this fix called for mirroring buildStateFrontmatter's filter UNCONDITIONALLY. Implemented GATED instead — an unconditional filter would ALSO move every LEGACY repo's persisted percent, since the milestone-scoping-vs- whole-disk divergence this closes is engine-wide, not bracket-specific. The gate keeps legacy byte-identical, which is the binding constraint: this is a bracket read-path PR, not a legacy behavior change. Nit 2 (informational, no code change): 10 calls to extractCurrentMilestone on a legacy repo cost 10 config.json existsSync + 10 readFileSync (0 before B3); accepted, unmemoized cost, unaffected by this commit. Also folds in two minors from the round-2 review: - Corrects .changeset/2761-bracket-read-tolerance.md: the sibling- exclusion sentence now states it holds at any heading level 1-3 and across a milestone split over two headings (true again now that Blockers 1 and 2 are fixed); the percent sentence states plainly that `state sync`'s body percent is now milestone-scoped under bracket, and unaffected under legacy. - Records the read/write scoping divergence at currentMilestoneRawRanges (src/roadmap-parser.cts) in a comment: it did not receive B1/B2's bracket boundary fixes, currently harmless (its only consumer falls back to whole-content mutation, and every mutation there is still Phase-labelled-only, not bracket-widened), but live the moment the write path is bracket-widened — flagged so a future PR closes it in lockstep with that work, not after. Tests: 6 pre-existing tests in tests/adr-612-bracket-phase-counting.test.cjs needed fixture updates, not logic changes — they used the default single directory (`GSD.02-01-setup`, phase "01"), which the SENTINEL/ retirement/mixed-heading fixtures in those tests never declare as a real phase (only 04/05/06/999/etc are declared). Before this fix, cmdStateSync's unfiltered scan counted that off-roadmap directory anyway; after this fix the milestone filter correctly excludes it, which for several of these fixtures made `state sync` a no-op (the computed 0% coincided with STATE.md's initial template default) and broke `syncedTotal()`/`syncedPercent()`'s ability to observe anything. Updated each to pass an EXPLICIT directory naming one of the fixture's REAL declared phases, preserving each test's original numerator/ denominator intent. One test — "shape 2 WRITE" — was substantively rewritten: it was a CHARACTERIZATION of the Major 1 bug itself ("the DISCLOSED legacy gap, mirrored — not closed"), and now correctly pins bracket closing to 33% (agrees with the read path) while legacy stays at the disclosed 60% (unchanged, deliberately, per the gating decision above). Full suite green: `npm test` 1449/1449 (0 fail, 0 skipped, 0 todo, single-shard "all" run — includes issue-2765-brace-expansion-lockfile passing); `npm run lint:ci` clean (0 errors; 2 pre-existing timing- assertion warnings in files this PR does not touch); node scripts/lint-phase-id-drift.cjs clean; node scripts/changeset/lint.cjs ok. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): preambleCutoff identity is offset- and child-aware (round-3 Blocker 1) Gate-2 round-3 re-verify Blocker 1 (NEW): the round-2 B1 deviation (39c42a89) threaded `selectedBracketId` as the real value at computeSectionEnd but as bare `null` at the preambleCutoff scan. The deviation's rationale — "the selected heading's own occurrence is always a correct earliest answer" — was right, but `null` disables the same-milestone check for EVERY candidate, not just the selected one. Any bracket-shaped heading earlier than the selected milestone was accepted as a boundary regardless of identity: a same-id checklist/ overview heading preceding the version-bearing selected heading (cases A, B — the version lands on the LATER half of a split, or a plain overview heading with no "(Phase Details)" spelling), or a DIFFERENT-id bracket-shaped PROSE heading with no children of its own sitting above the current milestone's content (case D — `## [ADR.612] Heading convention used by this roadmap`). In every case the region between that false boundary and the real sectionStart was silently dropped — a completed phase vanished and `state sync` persisted a confident 0% where base and round-1 both correctly wrote 50%. Regression vs base AND round-1 (not merely "under-fixed", per the round-3 review's own severity note). Fixed with two changes, both scoped to the preambleCutoff scan only (computeSectionEnd already threads the real `selectedBracketId` and is untouched): (a) `h.offset === sectionStart` now bypasses BOTH the same-milestone check inside isBracketMilestoneBoundary (passing the REAL `selectedBracketId` for every other candidate) and the new child rule below — the selected heading's own position is definitionally the correct answer, so neither discriminator should run against it (rejecting it would mean rejecting the heading against ITSELF). Closes cases A and B — verified by the reviewer's own one-liner, reproduced here. (b) New `bracketHeadingHasMatchingChild`: an otherwise-accepted candidate (bracket-shaped, not phase-tail-shaped, not the same id as the selected milestone) must ALSO have a next-strictly-deeper heading carrying its OWN bracket id to count as a boundary. This is what a genuine sibling milestone has (its own phase children share its bracket id — `## [GSD.01] Setup` / `### [GSD.01] 01: …`) and an unrelated bracket-shaped prose heading does not. A candidate with no such child at all (childless — e.g. an empty prior milestone, or one immediately followed by a same-or-shallower heading) degrades to NOT a boundary — over-inclusive, the safe direction: its own heading text stays in the preamble, contributing nothing to any phase count (not phase-shaped). Closes case D, which (a) alone does not — verified: without this rule, `[ADR.612]`'s prose heading is indistinguishable from a genuine prior sibling at this site. As a side effect, also neutralizes Nit 2 (a colon-less `[GSD.02] 05` heading spuriously terminating the preamble): a colon-less bracket heading is not phase-tail-shaped so isBracketMilestoneBoundary alone would accept it, but it is — precisely because it is malformed/ incomplete rather than a real milestone — childless, so the child rule rejects it too. Pinned. Known interaction with the fence-blind SELECTION path (disclosed by the reviewer, not introduced here, tracked for the next commit): when `sectionPattern` selects a FENCED version-bearing heading (an extremely pathological shape — a fenced example whose text happens to match STATE's asserted version), no token exists at `sectionStart`, so the `h.offset === sectionStart` bypass never fires and the loop falls through to the ordinary same-id / child-rule checks. This composes with the round-3 Major 1 fix (next commit) rather than introducing a new defect — SELECTION itself is untouched by any of this — but is worth stating plainly rather than rediscovering. Tests: new describe block "#612 PR-2 Blocker 1 round-3: preambleCutoff identity is offset- and child-aware" — RED-turned-GREEN for cases A, B (rv-attack1) and D (rv-attack1b) with syncedTotal()/syncedPercent() assertions (the persisted 0% is the point), a PIN for a genuine prior sibling with real children (still excluded), a PIN for a childless prior sibling (degrades to not-cutting, over-inclusive/safe), a PIN for the colon-less Nit 2 shape, and the reviewer's rv-mech1 mechanism re-run as a proper test (scope now equals the full input document, phaseCount 2, both dirs accepted).

A fenced VERSION-BEARING example heading in a bracket repo's preamble (ADR-612's own docs illustrate the LEGACY heading shape exactly this way, inside a fenced authoring-guide block) was still textually the earliest match for that raw regex, winning the min() and un-suppressing a wrong persisted 75% that base correctly suppressed (rv-attack3c fixture C1: base suppressed the percent entirely — `isMilestoneBounded` false — HEAD wrote 75% where truth is 50%). Fixed by deriving the version/emoji half from the SAME fence-aware `currentMilestoneHeadings` token list as the bracket half, on the bracket branch only — the exact `/^Phase\s+\S/i` / `/v\d+\.\d+|✅|📋|🚧/i` pair `computeSectionEnd` already uses against `h.text`. The non-bracket (legacy) path is untouched: it keeps the raw `content.match`, byte- identical to before, including its own fence-blindness (repro12's LEGACY control, pinned unchanged in the round-2 Blocker-3 test block — not re-pinned here to avoid duplicating an already-covered assertion). Not rated Blocker (per the review) because it is not a regression vs round-1 and the fixture (a version-BEARING fenced example in a bracket repo) is rarer than the already-fixed bracket-heading case; still fixed now rather than disclosed, per this arc's own precedent (every prior "disclose instead of fix" call in this PR has been overturned on re-review).

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): correct changeset claims + mark runtime-gated BASE_SITES row (round-3 minors) Gate-2 round-3 re-verify Minor 2: three changeset sentences in .changeset/2761-bracket-read-tolerance.md were overstated in a new direction after round-2: - The split-milestone claim ("across a milestone split over two headings") was true only when the version-bearing heading came FIRST (repro8 case 1); false when it came LATER (round-3 Blocker 1 case A). Now restated to say plainly "with the version-bearing heading in EITHER position" — true again now that round-3's Blocker 1 fix lands earlier in this range. - The "counted from the phases... rather than from every directory on disk" claim was false on cases A/B/D (a strict subset of the milestone's own phases). Restated as "ALL of the phases... not a subset", and extended to state that an unrelated bracket-shaped heading with no phase children of its own (case D's `[ADR.612]` shape) does not truncate the milestone either — true now, not before. - "Each widened read is SELECTED by the project's phase_id_convention" was literally false for BRACKET_PHASE_TAIL_RE, which is RUNTIME-gated (via its only caller, isBracketMilestoneBoundary, itself only consulted when bracketBoundaryActive) rather than selector-gated. Restated behaviourally: "every widened read ENGAGES only when the project's resolved phase_id_convention is bracket" — true for both gating mechanisms, so it no longer implies a selector call this site does not make. Minor 1: the STRUCTURAL IDENTITY test's BASE_SITES row for BRACKET_PHASE_TAIL_RE (added in the B2 commit) asserts a property of `phaseHeadingPrefixSrcFor` — the function — not of the call site; it would pass unchanged even if the site were deleted. Safety at that specific site rests entirely on a runtime gate the test cannot see. Added `runtimeGated: true` to the row and threaded it into the generated test's own title (`… [runtime-gated, not selector-covered]`), so the gating mechanism is visible in test OUTPUT, not only in a source comment that could drift silently.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): harden round-3 preamble cutoff — subtree child scan + level cap Team-lead review of f87bba0e found two edges in the round-3 preamble- cutoff code, both hardened here. AMENDMENT 1 — bracketHeadingHasMatchingChild (2e06aef5) checked only `headings[index + 1]`, the IMMEDIATE next heading, not the candidate's whole subtree. A genuine prior sibling milestone whose section opens with a non-bracket subsection before its first phase heading (`## [GSD.01] Setup` / `### Notes` / `### [GSD.01] 01: Old`) was therefore wrongly rejected as a boundary — its real phase heading sits TWO headings deep, not one — leaking its entire section into the preamble unstripped. CONFIRMED RED, not merely theoretical (built and ran the fixture against f87bba0e before touching the fix, per instruction): scope membership DOES drive the disk-side filter on this shape. `GSD.01-01-old`'s directory was wrongly admitted into the CURRENT milestone's filter via the leaked heading's qualified key (`GSD.01-01`) — 3/2/67% where truth is 2/1/50%. Fixed by scanning the candidate's full SUBTREE: continue past a non-matching deeper heading instead of returning false on the first one; only a same-or-shallower heading actually closes the subtree and yields "no match found". A candidate whose entire subtree closes with no same-id hit (including a genuinely childless one) still degrades to `false` — over-inclusive, safe, unchanged from before. AMENDMENT 2 — c483552a ported the version/emoji half of preambleCutoff to the token-based scan with no level cap; the raw `content.match(anyMilestonePattern)` it replaced was anchored `^#{1,3}\s+`. A level-4+ version-bearing heading in the preamble (`#### v2.0 notes`) therefore won the scan on the bracket branch where the raw pattern — and the legacy path, unaffected — ignores it outright. Fixed with `if (h.level > 3) continue;`, mirroring the depth-sanity cap isBracketMilestoneBoundary already applies to the bracket half of this same scan. Tests: new describe block "#612 PR-2 round-3 hardening: subtree child scan + level cap on preambleCutoff" — - RED-turned-GREEN for the Notes-intervening fixture: exact 2/1/50 (was 3/2/67), plus the disk-filter observable (`GSD.01-01-old` now correctly excluded). - PIN for the level-4 preamble heading: the scope now PRESERVES the heading's text (was silently dropped before this fix — harmless in this minimal fixture's total_phases specifically, since the dropped text carries no phase-shaped content, but a real correctness gap against the raw pattern's own ceiling) — asserted via scope content, not total_phases, since that number is invariant here either way. - PIN for the LEGACY control on the same level-4 shape — unchanged, confirming the raw content.match path is untouched. Re-verified the existing genuine-prior-sibling and childless-sibling pins (round-3 Blocker 1 commit) still pass under the subtree scan — both fixtures' outcomes are unchanged since their same-id hit (or its absence) was already at the first deeper heading.

Case F1 re-opens round-3's case D one heading later: `## [ADR.612] Heading convention` is followed by its OWN sub-heading `### [ADR.612] Examples` — same bracket id as the candidate, but MILESTONE-shaped (a name, no digit-then-colon), not a phase. Same-id-ness alone satisfied the subtree scan and re-cut the preamble at exactly the shape the round-3 hardening was written to close. Failing input: `## [ADR.612] Heading convention` / `### [ADR.612] Examples` (prose) / `### [GSD.02] 01: One` (the current milestone's own first phase, now unreachable) / `## [GSD.02] v2.0: Foundation` / `### [GSD.02] 02: Two`. Truth 2/1/50. HEAD read 1/0/0, and `state sync` reported "nothing to do" (exit 0, `{synced:true,changes:[]}`) because its wrong 0% happened to equal the STATE.md seed — a half-done milestone read as untouched with no write-path signal at all. Fixed with the reviewer's one-conjunct addition: a same-id child only counts if it is ALSO phase-tail-shaped (`BRACKET_PHASE_TAIL_RE`) — the same single-owner discriminator `isBracketMilestoneBoundary` already uses one level up for the identical distinction (phase vs milestone), reused here rather than re-derived. This is exactly what the changeset's own wording already claimed ("no phase children of its own") — the code now matches the sentence rather than the other way around. Docstring updated at the function itself: the rule is "same-id PHASE child", not "same-id child". Tests: new describe block "#612 PR-2 round-4 Blocker 1: the same-id child must be PHASE-shaped" — RED-turned-GREEN for F1 with syncedTotal()/syncedPercent() (the persisted 0% — and the report-nothing-to-do write-path silence — is the point), PINs for F11 (colon-less same-id child) and F11b (bullet-only phase list): both correctly stay excluded either way, and the leak the phase-shape requirement newly creates for these two shapes is INERT — a colon-less heading forms no qualified key (getMilestonePhaseFilter's own phase-heading pattern requires the colon too) and a bracket bullet never matches the legacy-only BULLET_PHASE_LINE_PATTERN — confirmed directly via getMilestonePhaseFilter, not merely inferred. Re-verified the four existing child-rule pins (F2 subtree-closure, F3 deep-nested same-id, F4 level-4 same-id, F5 childless-at-EOF) are unaffected by the phase-shape requirement, since every one of them already used a colon-bearing same-id child.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): fence-aware phase counting, milestone bounding, and bracket-fallback selection (round-4 Major 1) Gate-2 round-4 re-verify Major 1 (NEW): roadmapPhaseCount is a fence-blind raw `.exec()` over the scope string, duplicated in TWO independent copies (buildStateFrontmatter's read path, cmdStateSync's write path). With the bracket alternative now compiled into it (#612), a fenced EXAMPLE phase heading in the preamble inflates total_phases and persists a wrong percent that base got right. Two further fence-blind sites participate: isMilestoneBounded (a raw `.test(roadmapRaw)`) and the bracket-fallback SELECTOR inside extractCurrentMilestone (a raw `content.matchAll`, only reachable when version-string selection finds nothing). Failing inputs: - F10 (clean isolate, version-bearing selection): a fenced `### [GSD.02] 05: Example phase` in the preamble inflates total_phases 2->3, persisting 33% where truth is 50%. LEGACY control on the same shape is correct on every build — not a pre-existing hazard being inherited, bracket-only. - F9 (version-less selection): a fenced example carrying the project's OWN milestone id additionally confuses the bracket-fallback selector (the fenced heading gets SELECTED), compounding with the same fence-blind counter. base suppressed the percent; round-1 and HEAD both wrote 33%. - F12 (isMilestoneBounded isolate): the ONLY `[GSD.02]` heading in the document is inside a fence, and the asserted milestone genuinely has no section at all — HEAD persisted 67% where base correctly suppressed the percent (the milestone is absent from the roadmap). Fixed at the CONSUMER level, not the producer — extractCurrentMilestone's returned scope string is deliberately UNCHANGED, since every other consumer of that string needs its full content fidelity and legacy identity forbids touching the shared string (this branch's own precedent, ff6bf0a8/c483552a, was producer-level; here the ruling is consumer-level because the string is shared far more broadly than the two round-3 fixes' narrower producer edits): (a) New `countRoadmapPhaseHeadings` (src/state.cts, immediately above extractRetiredPhaseNumbers) — ONE shared implementation for both call sites, replacing two independently-maintained copies. BRACKET convention counts via `tokenizeHeadings(scope)` at levels 2-4, testing each heading's hash-stripped text directly — fence-aware by construction, since tokenizeHeadings never produces a token for a fenced line. LEGACY convention keeps the exact pre-existing raw `.exec()` loop, byte-for-byte. A pre-existing, deliberately PRESERVED asymmetry between the two original call sites — the read path always excluded a bare `/^999\b/` token, the write path never did — is threaded through as an explicit `includeUnconditional999Check` parameter per call site, so sharing the implementation does not silently unify (and thereby move) either total. (b) isMilestoneBounded's bracket branch now scans `tokenizeHeadings(roadmapRaw)` for a matching heading (level <= 3) instead of a raw regex test. Legacy version-string branch untouched. (c) The bracket-fallback SELECTOR now builds its candidate set from `tokenizeHeadings(content)` instead of `content.matchAll`, reconstructing a match-shaped array so every downstream consumer of `headingMatches` sees the identical shape the raw-regex path always produced. This is the ONE site in this entire arc where SELECTION itself changes — selection SEMANTICS are otherwise unchanged (same pattern, same first-match-wins by document order); only the candidate set is now fence-aware. Pinned that unfenced selection is byte-identical. Zero drift measured across the full historical corpus (repro2-13, rv-attack1/1b/3c, rv-mech1, rv2-amend1/2, and F1-F11b) except the three target fixtures.

No production code changed. Minor 1: bracketHeadingHasMatchingChild's own docstring said a rejected (no-same-id-PHASE-child) candidate's degrade "contributes nothing to any phase count" — true of the candidate's OWN heading text, but not of its SUBTREE, which is what actually stays in the preamble. F7 (`## [GSD.01] Setup` / `### [GSD.07] 01: Foreign`) shows a DIFFERENT-id bracket PHASE heading inside a rejected candidate's subtree DOES form a qualified key and CAN admit a foreign directory — 3/2/67%, stable across base, round-1 and HEAD (base via its own pass-all degrade). Not a regression, still the declared over-inclusive / never-under-inclusive safe direction — the comment now says that, with F7's numbers cited, at the call site that actually decides `isBoundary` (roadmap-parser.cts's preambleCutoff loop) rather than only at the helper's own definition. Minor 2 (changeset) — VERIFIED, no wording change needed: re-ran F1, F9, F10, F12 at this HEAD. The "no phase children of its own... does not truncate it either" sentence (naming the `[ADR.612]` shape directly) is now literally true — F1 reads 2/1/50. The "counted from ALL of the phases... not a subset" sentence is now true on every measured shape — F1/F9/F10 all read 2/1/50, F12 correctly suppresses the percent. No carve-out for F9/F10 is needed since round-4 Major 1 (3be5c412) closes both; per the fix-round instruction to "only carve out anything genuinely left," nothing is. Nit 1: tests/adr-612-bracket-heading-selection.test.cjs's runtimeGated row claimed `BRACKET_HEADING_INTRO_RE` has "no other consumers" — true when round-3's f87bba0e wrote it, stale since 2e06aef5 (round-3's own earlier commit) had already added two more uses inside bracketHeadingHasMatchingChild. Corrected to state the true count (three consumers) and re-confirm the conclusion is unaffected: all three are still nested inside the same bracketBoundaryActive runtime gate, and BRACKET_HEADING_INTRO_RE is built from BRACKET_ID_SRC, not phaseHeadingPrefixSrcFor, so it was never a selector site regardless of consumer count.

Every other isSentinelPhaseId call site in src/ (roadmap-parser.cts, roadmap.cts, validate.cts x2, verify.cts) keeps the guard; state.cts's shared counter was the only one of seven without it. When the phase-heading-intro grammar's LEGACY alternative matches (a `### Phase 00:` heading in a `phase_id_convention: "bracket"` repo — the mid-migration shape this PR exists for), the bracket capture group is `undefined`, so the unguarded call became `isSentinelPhaseId("undefined-00", 'bracket')` — measured TRUE, so phase 00 (and 000, 0a, 0.5, 999.1 — any token whose splice with the literal string "undefined" happens to fall in a sentinel range) was silently dropped from the denominator. `getMilestonePhaseFilter` (which still carries its own guard) counts the phase and admits its directory regardless, so the filter and the counter disagree — a half-done milestone reads as 100% complete, persisted. One-line fix, restoring the guard every sibling call site already has: if (bracketId && isSentinelPhaseId(`${bracketId}-${token}`, 'bracket')) continue; Line count: `git diff --stat src/state.cts` -> 1 file changed, 1 insertion(+), 1 deletion(-).

This PR compiles the bracket alternative into `introSrc` ("the retirement filter has to widen with the counter it protects" — the function's own pre-existing comment), so a FENCED authoring EXAMPLE showing the #1514 retirement gesture in bracket spelling is now indistinguishable from a real one: it retires a genuine phase, shrinking the denominator and persisting a confident 100% where base correctly read 50%. Fixed with the SAME consumer-level ruling this arc has used at every other fence-blind site, reusing markdown-sectionizer's existing exported `stripFencedCode` rather than hand-rolling a second fence parser (single-owner rule) — retirement lines are BULLETS, not headings, so `tokenizeHeadings` doesn't serve here; `stripFencedCode` is the general-purpose fence stripper the tokenizer itself is built on. Gated on `convention === 'bracket'`; the LEGACY line scan stays the raw `scope` string, byte-identical — its own fenced-example hazard is pre-existing (wrong at base too) and out of scope.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): state sync's counter excludes the bracket 999 icebox token (round-5 Major 2) Gate-2 round-5 re-verify Major 2 (NEW) — `includeUnconditional999Check` left `state json` and `state sync` reporting different totals for one bracket repo. Under bracket, READING-B puts the sentinel in the bracket, so `isSentinelPhaseId("GSD.02-999", 'bracket')` is false — the `/^999\b/` TOKEN rule is the only thing excluding a `### [GSD.02] 999:` icebox heading, and it ran on the read path (buildStateFrontmatter, `true`) and on getMilestonePhaseFilter (unconditional), but not on cmdStateSync's own counter (`false`). One `state sync` call could leave a single STATE.md with its own frontmatter (percent 50, from the read-path re-sync inside writeStateMd) and body (percent 33, from the write-path counter that alone still counted the icebox heading) disagreeing — falsifying this PR's own stated invariant that sharing countRoadmapPhaseHeadings made "the two counters must see the same phases" structural. Functional change is one argument, exactly as specified: the write call site now passes `syncConvention === 'bracket'` instead of the literal `false`. `syncConvention === 'bracket'` is `false` for every non-bracket value, so the LEGACY path resolves to the exact same `false` it always did — this file's own pre-existing, deliberately- unchanged read/write divergence on that path is untouched. The READ site (`:1860`) is NOT touched — its historical behaviour applied `/^999\b/` to legacy and bracket alike, so changing it would move legacy READ totals, exactly the class of mistake this arc's own Blocker 1 (this round) was. Line count: the functional change is ONE argument (`false` -> `syncConvention === 'bracket'`); the surrounding comment was rewritten because the previous one asserted the now-superseded behaviour ("preserving this file's pre-existing... divergence... a bare 999 token is not excluded here") and leaving it would mislead the next reader — not a structural change. Tests: new describe block "#612 PR-2 round-5 Major 2: state sync excludes the bracket 999 icebox token like the read path" — RED-turned-GREEN for G1, asserting `state sync`'s body percent equals `state json`'s own percent (both 50, not 33 vs 50), PIN for G1's legacy control (33 vs 50 unchanged, deliberately).

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): restore indent parity at the two line-start-anchored bracket-heading reconstructions (round-5 Minor 1) `HeadingToken.offset` (tokenizeHeadings) is the LINE-START character offset, not necessarily the `#` character's own offset — a ≤3-space-indented ATX heading has both. Two round-4 reconstructions built on tokenizeHeadings inherited this gap and accepted indented headings their raw, line-start- anchored predecessors (`^#{1,3}\s+\[...`) never matched: 1. roadmap-parser.cts's bracket-fallback SELECTOR (extractCurrentMilestone, ~line 377) — an indented, version-less `[GSD.02]` milestone heading could be reconstructed into headingMatches, then mis-parsed downstream (selectedBracketId null, level fallback to 1), leaking a SIBLING milestone's phases into the counted scope (G6: HEAD read 3/2/67 instead of 2/1/50 — a real phase heading's own directory belonging to the NEXT milestone got counted). 2. state.cts's isMilestoneBounded (~line 1571) — the same gap let an indented-only `[GSD.02]`-shaped heading wrongly bound a milestone absent from the roadmap, un-suppressing a percent that should stay suppressed (mirrors round-4's F12 fenced-only case, but via indentation instead of a fence). Fix: one added conjunct per site — `content[h.offset] === '#'` (source-named `roadmapRaw` in state.cts) — filtering to tokens whose LINE-START offset IS the `#` character, i.e. exactly the set the raw line-start-anchored regex would ever have matched. Restores byte-for-byte raw parity; no other logic in either function changes. computeSectionEnd and the preamble version/ emoji-token scan are untouched, as instructed — they consumed tokenizeHeadings output before this arc and are out of scope here. Also corrects roadmap-parser.cts's now-provably-false docstring claim that `h.offset` is unconditionally "the same `#`-character coordinate space `content.match().index` used" — true only for the survivors of the new filter, not for every token tokenizeHeadings produces. Line count: the FUNCTIONAL change is exactly 2 lines (one added `&&` conjunct per call site — `git diff --stat` on the two source files shows 20 insertions/7 deletions, but only those 2 lines change behavior; the rest is docstring/comment rationale, per this round's "state the line count" ask). TDD: both fixtures verified RED at HEAD before this commit, GREEN after, via /tmp/pr612rev/rv5-attack.cjs G6 and a locally-authored isMilestoneBounded- isolating probe (G6 alone doesn't distinguish the two sites — its unindented phase headings already satisfy isMilestoneBounded's loose prefix regex either way, so a second, indentation-only fixture was needed to prove that site's fix is not a no-op; verified by temporarily reverting just that one conjunct, confirming 100%-wrongly-bounded RED, then restoring it, confirming suppressed-percent GREEN). New tests (adr-612-bracket-phase-counting.test.cjs): - RED (G6): indented version-less bracket milestone heading — 2/1/50, not the pinned-before-fix 3/2/67. - PIN (G6c unindented control): identical document, no indent — 2/1/50 unaffected on every build. - RED (isMilestoneBounded site, indented-ONLY): mirrors round-4's F12 shape (fenced-ONLY → indented-ONLY) — percent stays suppressed instead of the pinned-before-fix wrongly-bounded 100%.

Both G4 and G5 moved from round-1's wrong (inflated) values back to base's original values as an incidental side effect of routing through tokenizeHeadings — never a deliberate feature of this PR, and previously undocumented. One clause added to the existing run-on paragraph; no other wording in the changeset touched. FIX 6 (Nit 1): tests/adr-612-bracket-heading-selection.test.cjs:76 — `BRACKET_PHASE_TAIL_RE` has TWO consumers as of round-4's 65d257ce (isBracketMilestoneBoundary's own use, plus bracketHeadingHasMatchingChild's same-id-PHASE-child conjunct), not the "no other consumers" the comment claimed. Same correction pattern round-4 already applied to this row's BRACKET_HEADING_INTRO_RE neighbor (that sentence's own staleness was fixed in 4d7184b8): note the true consumer count, confirm both stay nested inside the same bracketBoundaryActive runtime gate (verified at src/roadmap-parser.cts:178 and :250, both reached only through the `if (bracketBoundaryActive)` block starting at :529), and record which commit and which fix introduced the drift.

This is the identical failure one line further down, in the sibling rule this PR itself added: when the phase-heading grammar's LEGACY alternative matches (`### Phase 0:` in a `phase_id_convention: "bracket"` repo — the mid-migration shape this PR exists for), `bracketId` is `undefined`, and the unguarded `/^0\b/` fires on the bare token anyway. Neither the LEGACY branch of this same function nor `getMilestonePhaseFilter` has a `/^0\b/` rule at all, so the filter counts the phase and admits its completed directory while the counter refuses to count its heading — a milestone with an unstarted phase 02 persists as a confident 100%. `/^0\b/` matches `0` and `0.5` (word boundary before the `.`) but not `00` (no boundary between the two zeros), which is exactly why round-5's G3/G3d fixtures (`### Phase 00:`) never tripped this one — same defect class, different token spelling. Fix: one word, mirroring the guard round 5 restored two lines above — `if (/^0\b/.test(token)) continue;` -> `if (bracketId && /^0\b/.test(token)) continue;`. Expected and intentional side effect: `roadmap analyze` and `state json` now disagree again on this bracket-repo shape (analyze phase_count=2, json total_phases=3) — exactly as they already do under the legacy convention today (verified via /tmp/pr612rev/rv6c.cjs on both conventions). That is the counter regaining agreement with `getMilestonePhaseFilter` (the tighter constraint — it is what actually decides `completed_phases`), not a new break; the counter/filter disagreement is what was wrong. Out of scope, deliberately NOT fixed here (Minor 1, disclosed via a PIN test only): the bracket-SPELLED `### [GSD.02] 0:` shape has the same counter/filter disagreement, but reads 2/2/100 on base too — never closed by any build in this arc, so it is a pre-existing gap rather than a regression this commit could introduce.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): changeset re-attributes the phase-count level cap + discloses the bare-0 carve-out; correct two stale test comments (round-6 Minor 1 + Nits) FIX 2 (Minor 1 — disclosure only, NOT a code fix): the bracket-SPELLED `### [GSD.02] 0:` / `0.5:` shape has the same counter/filter disagreement round-6's Blocker fixed for the legacy spelling, but it reads 2/2/100 on BASE too — never closed by any build in this arc, so it is a pre-existing gap rather than a regression this round could introduce. Two changes: - Pinned as a base-parity characterization: new PIN test (B0) in 04b5a95f's describe block asserting the exact unchanged value with a comment stating why it's deliberately not touched. - .changeset/2761-bracket-read-tolerance.md: one qualifying clause added to the "counted from ALL of the phases … not a subset" sentence — a bare `0`/`0.x` phase token (however spelled) keeps `roadmap analyze`'s own pre-existing sentinel reading under bracket too, so it stays excluded from these counts. Carried over, not newly introduced by this PR — `roadmap analyze` has always read it this way. FIX 3(a) — same changeset paragraph misattributed the phase counter's 2-4 level cap to "the milestone-boundary machinery in this PR" (the selector, `isMilestoneBounded`, the preamble scan) — that machinery caps at `###` (level ≤3), not 2-4. The 2-4 cap belongs to `getMilestonePhaseFilter`'s own phase scan. Re-pointed the attribution; the paragraph's earlier, correct ≤3 claim (selector/isMilestoneBounded) is untouched. FIX 3(b) — tests/adr-612-bracket-heading-selection.test.cjs:76-82 (added by 1395bd89, round-5's own Nit-1 correction) claimed both `BRACKET_PHASE_TAIL_RE` consumers are reached "only through the `if (bracketBoundaryActive)` block starting at :529". Verified at HEAD: `bracketHeadingHasMatchingChild` is (only caller :593, inside that block). `isBracketMilestoneBoundary` is not — it has two callers, an inline `bracketBoundaryActive &&` conjunct at `:473` (inside `computeSectionEnd`) and the `:529` block at `:567` — the very fact this row's own earlier "exactly two callers" paragraph already stated correctly. Corrected the mechanism claim; the CONCLUSION (every consumer is still gated on the same flag) is unchanged, exactly as round-5's own Nit-1 fix left round-4's conclusion unchanged when it corrected the consumer count. FIX 3(c) — tests/adr-612-bracket-phase-counting.test.cjs:2311,2340 still said "four fence-blind sites" after round-5 (357ba671) added a fifth (the retirement scan) in its own block below. Reworded both the section comment and the `describe()` label to read as historical scoping of round-4's own fix ("the four sites known at round 4 … a fifth was found at round 5, see its own block below") rather than a live exhaustive claim. Line count: 3 files, changeset 1/1, heading-selection test 17/8, phase-counting test 6/2 (comment/prose-only; B0's own PIN test landed in 04b5a95f alongside T0/T05 since it was investigated as part of that same Blocker's defect class, not in this commit — noted here for the record). Verified: targeted suite (adr-612-*, roadmap-parser, state, verify) unchanged at 970/970 (comment/prose-only diffs, no test count change). `npx eslint` and `node scripts/changeset/lint.cjs` both clean. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): W021's bracket remediation hint stops pointing at a command that hard-errors (round-7 Minor 2) `checkBracketCoherence`'s W021 (added by 94abf5df) attached the fix hint `Run \`gsd-tools roadmap upgrade --convention bracket\` to migrate (dry-run by default)` to every bracket-convention W021 — both sub-checks (`missing-bracket` and `mismatch`) share the single `addIssue` call at src/verify.cts:2255-2256. But `roadmap-command-router.cts:204` throws unconditionally for any `--convention` value other than `milestone-prefixed`: $ gsd-tools roadmap upgrade --convention bracket Error: Only --convention milestone-prefixed is supported This contradicts the PR's own two disclosures: the changeset ("`bracket` is a READ-path opt-in until the migrator and write path land") and docs/CONFIGURATION.md:188 ("There is no bracket migrator and no bracket emit yet"). Reachability is the exact mid-migration repo this PR targets — any bracket project with one un-migrated heading gets an unfollowable instruction on every `validate health`. Fix: one string. Replaced the hint with what a user can actually do today — manually align the heading's bracket milestone to its section — and named the tracked future landing (#612 PR-3) instead of a command that errors. The milestone-prefixed sibling hint at src/verify.cts:2240 (a different, already-functional convention/command pair — verified against roadmap-command-router.cts:65) is untouched. Line count: src/verify.cts is exactly 1 insertion / 1 deletion (one string literal). No test in the suite previously asserted this string's content (`grep -rn "upgrade --convention bracket" tests/` was empty), so the unfollowable hint shipped unpinned — `lint-fix-has-regression-test.cjs` would not have caught a string-only change without a new test. Added one: asserts the fix string both (a) does not match `--convention bracket` (the specific pinned-before-this-fix hazard) and (b) equals the new string exactly, covering the invariant a future edit must not re-break: no unsupported `--convention` value named in remediation text users are expected to run verbatim. Verified end-to-end (not just unit-level) via /tmp/pr612rev/rv7f.cjs: the W021 issue's `fix` field now reads the new string; `gsd-tools roadmap upgrade --convention bracket` (and its --dry-run variant) still correctly hard-error — that command remains unsupported, only the hint text changed. Targeted suite (adr-612-*, roadmap-parser, state, verify): 970 -> 971 (+1), 0 fail. `lint-phase-id-drift.cjs` clean; `npx eslint` on touched files: 0 errors (1 pre-existing unrelated no-elapsed-assertion warning, same file, same line this arc's prior rounds already disclosed). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): correct the bare-0 changeset disclosure + disclose W021's second sub-check (round-7 Minor 1 + Nit 1) FIX 1 (Minor 1) — round-6's bare-0 changeset clause (1395bd89) was wrong in three falsifiable ways: (a) Its own illustration (`### Phase 0:`) is exactly the LEGACY spelling 04b5a95f made COUNTED. The residual exclusion after that fix applies only to the BRACKET-spelled token (`### [GSD.02] 0:`) — the clause named the wrong shape as its example. (b) "excluded from these counts" over-scoped the carve-out. The phase-0 directory is admitted into `completed_phases`/`total_plans` in BOTH spellings (measured: B0 at HEAD has `completed_phases=2`, `accepts {"GSD.02-0-bootstrap":true}`). The exclusion that survives lives in `total_phases`/`phase_count` (heading counting) only. (c) The pre-existing "so `roadmap analyze` and `state json` report the same number" sentence (present since before this arc's bracket work) is now false for the bare-0 LEGACY-spelled shape: 04b5a95f's own commit message discloses this exact re-divergence as expected — `roadmap analyze` phase_count=2 vs `state json` total_phases=3 on T0 — matching the disagreement legacy already carries today. The changeset still asserted unconditional agreement. Rewrote both sentences: dropped the `### Phase 0:` example, scoped the carve-out to `total_phases`/`phase_count`, named the bracket-spelled token as the one that keeps analyze's sentinel reading, stated plainly that the legacy-spelled form in a bracket repo IS counted (the mid-migration guard), and qualified the "report the same number" claim to the `999` token, with the bare-0 legacy-spelled shape named as the one exception and why. FIX 3 (Nit 1) — `checkBracketCoherence` has always had two sub-checks (its own docstring: "Two sub-checks, both surfaced as W021") but both the changeset and docs/CONFIGURATION.md:188 described only the `mismatch` sub-check. The `missing-bracket` sub-check — which fires on every legacy-spelled heading in a bracket repo, the noisier of the two on a mid-migration project — was undisclosed in both places. One clause added to each. Line count: 2 files, 1 line changed each (both are single-paragraph/ single-row files; git diff --stat reports 1/1 per file though several distinct clauses were edited within that one line each). Verified: `node scripts/changeset/lint.cjs` clean. Targeted suite (adr-612-*, roadmap-parser, state, verify) unchanged at 971/971 (prose-only diffs, no test count change, no code touched). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): resolvePhaseIdConvention's docstring no longer claims loadConfig drops the key Upstream #2997 (aa7697fe, landed in `next` during this PR's final verification) added `phase_id_convention: get('phase_id_convention') ?? null` to `_baseConfig` in config-loader.cts — `loadConfig` now surfaces `phase_id_convention` in its resolved config. This function's docstring gave "loadConfig merges against CONFIG_DEFAULTS and drops keys it does not know, and `phase_id_convention` is not among them" as the reason for reading config.json directly instead of calling `loadConfig(cwd)`. That rationale is now stale against live `next`. Corrected the comment to state the two reasons that actually survive #2997: 1. The workstream->root federation this function performs is a standalone resolution run against a GIVEN cwd, not necessarily the same base a `loadConfig(cwd)` call elsewhere in the codebase would federate from. 2. Convention-ENUM validation is still #612 PR-4 work — this function returns the raw string unvalidated, exactly as the now-surfaced resolved key would. Noted that #2997 surfacing the key makes consuming it from resolved config (instead of re-reading config.json here) a natural PR-4 consolidation — not this PR's scope. The "cycles were never the obstacle" close and every other paragraph in the docstring (federation rationale, SCOPE note) are untouched; they still hold. Comment-only — no code behavior changed. This worktree's own history does not contain aa7697fe (git merge-base --is-ancestor confirms neither branch is an ancestor of the other; not rebasing per instruction), so this is a textual correction against a documented external fact, not a functional sync with upstream. git diff --stat: src/planning-workspace.cts | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) Verified: `npm run build:lib` clean, `node scripts/lint-phase-id-drift.cjs` clean, `npm run lint:ci` exit 0 (same 2 pre-existing unrelated eslint warnings as every prior round this arc, 0 errors; lint-fix-has-regression-test PASS). Full suite not re-run per instruction (comment-only diff). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#2761): resolve phase_id_convention against the caller's workstream `resolvePhaseIdConvention` took no workstream, so it resolved from `planningDir(cwd)` — which falls back to `GSD_WORKSTREAM` only when its `ws` argument is `undefined`. Every caller that passes a workstream by ARGUMENT (they cannot set the env var per iteration) therefore read the convention from the ROOT config while reading that workstream's ROADMAP. Two reproduced consequences: - A workstream that explicitly declares its own `phase_id_convention` had it ignored. Flipping ONLY the root config between bracket and milestone-prefixed changed which milestone that workstream extracted. - `--workstream foo` and `GSD_WORKSTREAM=foo` disagreed on the same repo: the arg form fell through to the root config, the env form did not. `resolvePhaseIdConvention(cwd, ws?)` now forwards `ws` to `planningDir`, and both roadmap-parser call sites pass theirs — `extractCurrentMilestoneScoped` (which already reads STATE from `planningDir(cwd, ws)`) and `getMilestonePhaseFilter`'s lazy branch. `undefined` keeps the env fallback, so convention-less call sites are byte-identical; `null` still means "explicitly no workstream". The `undefined` vs `null` discriminator on `phaseIdConvention` is untouched — only the base the `undefined` branch resolves FROM moves. workstream-inventory's two sites (`countRoadmapPhases`, `inspectWorkstream`) passed a literal `null` where they meant `undefined`, pinning every workstream to the legacy grammar. On a bracket workstream whose milestone declares 3 phases that returned phaseCount 0 and fell back to the on-disk directory count; it now returns 3. A non-bracket workstream is unchanged (legacy control pinned). The workstream -> root federation is preserved: a workstream that declares no convention still inherits the root, as config-loader does. That inheritance is pinned so the fix cannot be over-applied into isolation. * fix(#2761): classify missing phase details per occurrence, not per token Under READING-B a phase's sentinel status lives in the BRACKET, so `[GSD.999] 01` and `[GSD.02] 01` share a token and are not the same phase. Both sides of the missing-detail check were keyed by the bare token anyway, and both produced false negatives in `missing_phase_details`: - The checklist scan built a token -> bracket-id Map, FIRST-WINS. Of two entries sharing a token, whichever the author wrote first classified both. With `- [ ] **[GSD.999] 01: Icebox**` above `- [ ] **[GSD.02] 01: ...**` the real phase inherited the icebox's sentinel verdict and vanished from the report; swapping the two bullets — same document, same phases — reported it. Pinned with a test asserting BOTH orders. - The detail set was `new Set(phases.map(p => p.number))`, also token-keyed, so `[GSD.02] 01`'s heading marked token `01` present and satisfied `[GSD.03] 01`, which has no heading anywhere. Order-independent, same class. Both sides now key on an occurrence key: the owner's `bracketQualifiedKey` (fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one phase), falling back to a fold-normalized composite for the two shapes that grammar refuses — a token carrying its own hyphen, which splices to an id whose trailing segment the qualified-key grammar truncates (the hazard `getMilestonePhaseFilter` guards with its own `!token.includes('-')`), and any id it does not accept. With no bracket id the key IS the bare token, so the legacy path keeps its exact keys and dedupe order. The emitted value is unchanged — `missing_phase_details` stays an array of bare tokens, matching `phases[].number`. Only the classification moved to the qualified key, so two brackets' `01` both missing report `01` once instead of one silently covering for the other. * test(#2761): replace the two wall-clock ReDoS assertions with algorithmic bounds Both guards asserted elapsed wall-clock time — `Date.now()` against a 20s ceiling in the coherence suite, `process.hrtime.bigint()` against 1s in the read-tolerance suite. Those measure the host machine rather than the SUT and flake on a loaded CI runner (RULESET.TESTS.no-timing-assertion). Per RULESET.TESTS.delete-bad-tests they are REPLACED, not skipped, and the behavioral property each one guarded is preserved. The property is "the widened bracket patterns do not backtrack catastrophically", which is a claim about growth, so it is now stated by scaling the input instead of by timing it: - validate health runs the pathological unclosed bracket at 4,000 and 16,000 characters and must return the same correct result (no W021) at both. - The four reader entry points run five ReDoS shapes at 5,000 and 20,000 and must name exactly the phases each shape should name at each size, with the variant cardinality unchanged across the two. Catastrophic backtracking is superlinear, so a regression cannot complete the 4x leg under any ceiling, while a bounded matcher is indifferent to the scaling. The one attack that is well-formed-but-oversized now pins its reading precisely (`['1'.repeat(n)]`) rather than being lumped in with the malformed ones. A positive control asserts the readers still extract a well-formed bracket heading, so "names no phase" cannot pass by the readers being inert. `{ timeout }` is a hang backstop, not an assertion: it turns a runaway into a deterministic failure instead of a suite that never returns. * fix(#2761): give the bracket grammar one owner and teach the drift guard to see it The bracket milestone-intro grammar was re-typed verbatim in three readers — roadmap-parser's bracket-fallback selector, state's `isMilestoneBounded` and verify's `checkBracketCoherence` — which is exactly what #2761's own gate forbids ("no token literal outside src/phase-id.cts"). `check:phase-id-drift` reported clean the whole time: its detector only ever knew the phase-NUMBER token grammar, so the bracket class `[A-Z][A-Z0-9_]*` was invisible to it. Ownership. `src/phase-id.cts` now exports the class as `BRACKET_PROJECT_CODE_SRC` and the intro in the two shapes its readers need: `bracketMilestoneIntroSrcFor(milestone)` (pinned to one milestone) and `BRACKET_MILESTONE_INTRO_CAPTURING_SRC` (milestone captured). The pinned builder owns the pad2 spelling rule too — "canonical spelling only, not `0*N`" was previously restated in prose beside each copy, a convention two files had to keep agreeing on by hand. `BRACKET_ID_SRC`, `BRACKET_ID_PREFIX_RE` and `BRACKET_QUALIFIED_KEY_RE` now compose the class rather than re-spelling it. All three call sites consume the owner; the regex sources are byte-identical to what they spelled, asserted against hand transcriptions of the pre-fix lines. Guard. `scripts/lint-phase-id-drift.cjs` gains a bracket rule (`findBracketGrammarDrift`), wired into `scanRepo` and tagged `kind`. It deliberately does NOT copy the token rule's `line.includes(CANON_REF)` escape: that escape is line-level, and verify's copy referenced the owner for the MILESTONE field on the same line as the re-typed PROJECT-CODE class — so a bracket rule with that escape would have kept passing on the very site under review. Partial ownership is the drift; only a dedicated `// phase-id-owner:` comment suppresses it. Proof, end to end: planting the shipped verify.cts literal back into src/ makes `npm run check:phase-id-drift` exit 1 naming `[bracket] src/verify.cts:1475`; restoring it returns the gate to ok. Tests. phase-id-drift-guard carries all three shipped literals as negative fixtures, the same-line-owner-reference case, the case-widened evasion variant, the sanction rules, and a temp-tree scan proving the rule is wired into scanRepo rather than merely exported. continuation-grammar-parity drives the pinned and capturing shapes over a 12-entry corpus and requires the same verdict from both plus the same captured milestone — widening either alone fails there. * test(#2761): drop the out-of-scope source-grep exemption from the selector pin The baseline-selector pin in tests/adr-612-bracket-heading-selection.test.cjs read `src/*.cts` with readFileSync and regex, claiming the no-source-grep escape with a source-text-is-the-product reason. CONTEXT.md's documented scope (RULESET.TESTS.no-source-grep.exemption) reserves that escape for tests whose subject is a runtime CONTRACT FILE — STATE.md, config.toml, hooks.json, agent .md — and `src/*.cts` is none of those. It was also broader than it looked: eslint-rules/no-source-grep.cjs matches the marker in ANY comment in the file, so one block's claim disarmed the rule for the whole ~700-line suite. The pin itself is worth keeping — the BASELINE ARGUMENT at each call site is a fact no behavioural test can recover (flipping verify's milestone-complete site from LABEL_ONLY to ANY_BRACKET grants a tolerance it has never had, and every behavioural test still passes), so pinning it does require reading the authored source. That reading moved to `scripts/lint-phase-id-drift.cjs` — the seam's own guard, where source scanning is sanctioned (`warn` scope) and already happens for the grammar rules — as `countSelectorBaselines` / `scanSelectorBaselines`, which return a structured census. The test asserts on the returned data and touches no file text. CONTEXT.md is unchanged: the exemption scope was not widened to fit the test. No marker remains in the suite, so the rule is live across all of it again, and eslint passes with the escape removed rather than relocated. A floor assertion pins that the census actually found the five consumers, so the "no other file consumes the selector unpinned" check cannot pass on an empty scan. * docs(#2761): rewrite the changeset as a lead + deltas instead of one paragraph The fragment was a single ~6,400-character paragraph that opened on internal mechanics, buried the user-visible change, and named an internal test path (tests/adr-612-bracket-phase-counting.test.cjs) that means nothing to a reader of the CHANGELOG. It now leads with what a user sees — bracket-style phase IDs are recognized on the read path across roadmap, validate, verify and state — followed by compact bullets for the behavioral deltas, the opt-in caveat, and the upstream consequences. Both merge-added disclosures are kept: the #3185 legacy-sentinel Phase-0 delta with the reason the bracket counter keeps the narrower rule, and the enumerator's convention-argument default flip with the four newly-scoped read surfaces and the note that archival and milestone-completion paths are unchanged. Two deltas from this review round are stated as their own bullets: per-occurrence classification in `missing_phase_details`, and workstream-scoped convention resolution including the workstream-rollup count change. The internal test path is gone and the body is down to ~3,850 characters. The bullets render as sub-bullets under the CHANGELOG entry and the `(#NNNN)` suffix still lands on a trailing paragraph rather than mid-list. `npm run lint:changeset` passes. * test(#2761): use helpers.cleanup in the drift-guard temp-tree test `local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in tests — the shared helper carries the Windows-EBUSY retry budget. The temp-tree scan added with M3's guard coverage test used the raw call. * docs(#2761): correct the occurrenceKey comment on qualified-key normalization The comment claimed `bracketQualifiedKey` is "fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one phase". The fold half is right; the padding half is not. `BRACKET_MILESTONE_NUMERIC_SRC` is `(?:[1-9]\d{2,}|\d{2})`, so `bracketQualifiedKey('GSD.2-01', 'bracket')` returns null and that input takes the composite fallback instead. No behavior change — the two key spaces use different separators and cannot collide — but the claim was checkable and wrong. Restated: the owner case-folds, and padding-tolerance is not a property it has or needs, because each accepted milestone has exactly one canonical spelling and `[GSD.2]` is malformed rather than an alternate spelling of `[GSD.02]`. * ci(#2761): give the coverage-gate job the heap floor the shard jobs already have The gate's report steps parse ~2.5GB of merged raw V8 dumps in one process at the runner's implicit ~4GB ceiling, so pass/fail comes down to GC timing (run 31338081337 OOM'd; next passes the same volume at 28s). Deterministic locally: crashes at --max-old-space-size=4096, completes in 11s at 8192. PR shard data is within 0.15% of green next runs — the load is pre-existing, only the ceiling was missing. #2952 set 6144 on the shard-collection step; the gate job was missed. * Revert "ci(#2761): give the coverage-gate job the heap floor the shard jobs already have" This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1. * fix(#2761): thread the resolved convention into cmdStateValidate's phase-directory lookup #3208 replaced cmdStateValidate's `startsWith` prefix test with the canonical `phaseKeyFromDir(...) === selectedPhaseKey` comparison. That is the right surface, and it is why the lookup now needs the resolved `phase_id_convention`, which the rewrite does not pass. `phaseKeyFromDir` deliberately refuses to read a bracket directory without an explicit signal (ADR-2121: a bracket dir is string-indistinguishable from the legacy letter-prefixed-decimal family), so un-threaded it returns the whole dir name as the key — `GSD.02-05-real-work` -> `GSD.02-5-REAL-WORK` — while the STATE side is the bare `05` that `parsePhaseFromProse` yields. Both sides of one comparison derived under different conventions is #2562's defect class, and this file's other three `phaseKeyFromDir` call sites already thread against it. Observable: a bracket repo whose phase directory plainly exists reported `valid: false` and "no phase directory matches phase 05", and the drift scan (plan-count mismatch, verification status) never ran. The pre-#3208 `startsWith` missed the same directory but skipped silently, so this is a visible-failure regression on bracket repos, not a new miss. Non-bracket conventions are byte-identical by construction: `extractPhaseToken` branches only on `=== 'bracket'`, so null / 'milestone-prefixed' / unresolvable compile the same path as the un-threaded call. The flat-legacy twin assertion pins that. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#2761): note the cmdStateValidate convention threading in the changeset fragment The fragment described the bracket read path as of the pre-merge branch. 504c64ff added a shipped behaviour change — `state validate` now resolves bracket phase directories — that the fragment did not mention, so the rendered changelog would have under-described what ships. Body text only; `type` and `pr` are untouched. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2761): invert the inherited-wart characterization — #3225 fixed it upstream Required by the merge of next @ 86101ee6; test-only, no src delta. This branch disclosed rather than fixed a pre-existing upstream wart: on a LEGACY repo, `### Phase 999:` warned from `validate consistency` while `validate health` suppressed it — the two verbs contradicting each other. The case was pinned as a characterization test ("INHERITED WART, unchanged") precisely so it would INVERT if upstream ever closed it, rather than rot silently. ae7dc529 (#3225) closed it, by adding the `isSentinelPhaseId` guard to this very loop. So the assertion inverted on the merge — as designed. Flipped to assert the FIXED behaviour rather than deleted: it is the negative-space proof that this branch's `sentinelPhases` guard never had to grow a legacy reading of its own, and it reds if a future conflict resolution keeps our guard while dropping upstream's. Added a scope control alongside it (a legacy NON-sentinel `### Phase 09:` with no directory still warns), so deleting the loop outright cannot pass. Union proven load-bearing in BOTH directions against the merged tree — neither guard subsumes the other: - drop `isSentinelPhaseId(p)` (ours only) -> 1 red, exactly this case. Note upstream's own #3225 tests stay GREEN there: they cover the disk-side loops (sentinel dir on disk) and the gap-numbering filter, not the ROADMAP-side loop. This case is that site's only coverage, which is the second reason to keep it rather than delete it. - drop `sentinelPhases.has(p)` (upstream only) -> 4 red bracket suites (icebox-not-missing, health/consistency agreement, occurrence-aware suppression, checklist-index suppression). tests/adr-612-bracket-read-tolerance.test.cjs 79 -> 80, all green. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2761): pin the three re-homed W006/W007 reads the merge left unfalsifiable #3309/#3310 deleted the helpers this PR threaded (collectDiskPhases, collectDiskPhaseEntries, collectArchivedPhaseDirNames, forEachArchivedPhaseToken) and rebuilt their reads inside src/planning-snapshot.cts + src/health-diagnostic-rules/*.cts. The convention threading moved with them in the merge commit — but a mutation sweep over the re-homed sites found three where reverting the convention argument changed real CLI output and NOT ONE existing test went red. The pre-migration sites were covered indirectly, through helpers that no longer exist, so the coverage did not survive the relocation even though the behaviour did. Each case is pinned at the CLI with its flat-legacy twin as the byte-identity control, plus a non-vacuity control in the opposite direction: archivedPhaseTokens revert -> "Phase 05 in ROADMAP.md but no directory on (planning-snapshot.cts) disk" for a phase whose only directory is under .planning/milestones/v1.0-phases/ roadmapPhaseCheckboxes revert -> "Phase 09 in ROADMAP.md but no directory on (planning-snapshot.cts) disk" for an unstarted `- [ ]` phase W007's extractPhaseToken revert -> "Phase GSD.02-77-orphan exists on disk" (roadmap-disk-consistency) instead of "Phase 77 exists on disk" Red/green: each single-line revert reds exactly its own case and nothing else; every legacy control stays green in all three runs. NOT pinned, and disclosed as droppable rather than given an unfalsifiable test: buildValidPhaseSet's extractPhaseToken(dir, convention) in W002. That rule unions disk tokens with roadmapDeclaredPhases and archivedPhaseTokens, and any STATE.md reference a bracket disk token would rescue is already rescued by the ROADMAP half — probed directly, the argument makes no observable difference. It is threaded because it restores collectDiskPhases(planBase, convention)'s derivation exactly, not because a test needs it. Test-only; revertable independently of the merge commit. * test(#2761): pin the two reads the #3165 extraction left unfalsifiable DROPPABLE, offered as such. Test-only; the merge commit is correct without it. #3428's extraction gave `collectAnalyzePhases` TWO call sites — the scoped milestone window and the truncated-window recovery path. The merge threads `convention` into both and swaps `detailKeys` with `phases` across the recovery. Neither of those was falsifiable by the suite as it stood: - passing a NULL convention at the FALLBACK site, with the scoped site still threaded, is green across all 518 tests of the bracket, roadmap and milestone-window files. Every pre-existing bracket assertion reaches the enrichment through the scoped window, so none of them can observe the fallback's reading at all; - dropping `detailKeys = fallbackScan.detailKeys;` — the line this merge authored — is likewise green, because no fixture that reaches the recovery path carries a checklist bullet, so `missing_phase_details` is `null` either way. That is the same hole class lap 3 closed in 9914359c: an argument whose revert changes real CLI output with zero reds. Pinned at the CLI on the shape that reaches the fallback on a bracket repo — a MID-MIGRATION ROADMAP: bracketed ACTIVE milestone, its phase-detail sections and checklist bullets sitting after an intervening CLOSED legacy milestone (so the window closes over prose only), plus one legacy `### Phase N:` section of its own. Six tests: - a NON-VACUITY control that removes the phase directories, so #3428's own precondition fails and the result is the empty one the recovery exists to replace — this is what proves the rest read the FALLBACK's output rather than the scoped scan's; - the directory assertion (`disk_status`/`plan_count`/`summary_count` for canonical `{CODE}.{MM}-{PP}-slug` dirs) + a flat-legacy twin asserting byte-equal shape, and that the twin is the right answer rather than a shared wrong one; - `missing_phase_details: null` for phases the recovery just found, and its companion direction — a bullet with no heading anywhere is STILL reported, so a fix that merely suppressed the report does not pass; - a non-bracket repo taking the same path unaffected. Red/green, each mutation reverted afterwards: - fallback call site -> `null` convention: exactly 2 reds, both directory assertions in this block; 307 other tests green, including upstream's own #3428 tests in tests/milestone-window-single-owner.test.cjs. - `detailKeys` swap deleted: exactly 2 reds, both `missing_phase_details` assertions; 414 other tests green. - `matchPhaseDirs` 3rd argument dropped (the lap-2 site): 4 reds — the 2 already on record plus this block's 2, which is the point: one seam, now reached by two paths. DISCLOSED IN THE TEST BODY WITH MEASURED OUTPUT, not fixed: `hasPhaseEntries` (src/roadmap-parser.cts) is convention-blind, so on a PURE-bracket ROADMAP the window classifies COMPLETE and #3428's recovery is gated off entirely. That document returns `{"scope":"complete","phase_count":0,"next_phase":null, "phases":[]}` — the "genuinely empty milestone" answer, the indistinguishability #3184 introduced `scope` to remove — where the flat-legacy twin returns `{"scope":"truncated","phase_count":2,...}`. Widening it changes the value of an upstream-owned output field on bracket repos, so it is a behaviour slice (the PR-2.5/PR-4 convention-less-readers question), not a merge-round change. The mid-migration shape pinned here is the reachable half. * fix(#2761): mirror the bracket terminator in the milestone-scope write guard parser's terminator vocabulary — "a level 1-3 heading that is not a Phase heading and carries a milestone signal". On this branch that vocabulary is convention-SELECTED: `computeBracketSectionEnd` adds `isBracketMilestoneBoundary` as a terminator arm, and the ADR-canonical `## [GSD.09] Hidden` carries NO vN.N token, NO ✅/📋/🚧/🔄 marker, and not the word "Milestone". Left unmirrored, the guard accepted exactly the description it exists to reject. NOT a defect on clean next — a bracket heading terminates nothing there. The branch widens the terminator set, so the branch owns the mirror. MEASURED at the CLI seam before the fix (bracket fixture, one milestone, one phase): $ gsd-tools phase add $'Sneaky\n## [GSD.09] Hidden' -> exit 0, written $ gsd-tools phase add 'Innocent follow up' -> exit 0, written $ gsd-tools roadmap milestone-scope { "scope": "complete", "phases": ["01","1"], "phase_count": 2 } $ grep '^### Phase' .planning/ROADMAP.md ### Phase 1: Sneaky ### Phase 2: Innocent follow up <- in the document, out of the window After the fix the first add exits 1, ROADMAP.md is byte-unchanged and no phase directory is created. The legacy twin (same text, no `phase_id_convention`) still exits 0 — opt-in only, base behaviour preserved. SHAPE - `findMilestoneScopeHeadingLines(text, convention)` — REQUIRED, the same tripwire `scanMilestonePhaseIds` carries in the merge commit and for the sharper reason: a blind call here fails OPEN (the guard quietly ACCEPTS a window-narrowing description), so a future call site must fail to COMPILE. Census is one caller, which pays nothing for it. A non-bracket value takes the pre-existing path byte-identically. The bracket arm routes through `isBracketMilestoneBoundary`, the same single-owner phase-vs-milestone discriminator `computeBracketSectionEnd` consults; no second bracket-heading grammar is spelled here. - `selectedBracketId` is deliberately `null`, so the same-milestone CONTINUATION exemption never fires and a value naming the ACTIVE milestone is flagged too. That is this predicate's third stated conservatism and rests on its own existing argument: which milestone is active is a property of the document at write time, not of the text being validated, and over-rejecting is one-directional. - `assertDescriptionPreservesMilestoneScope` takes `cwd` and resolves through the branch's tolerant try/catch — this guard runs BEFORE `loadConfig` and before the ROADMAP existence check, so an unresolvable convention must degrade to the legacy vocabulary, never turn a rejection into a crash. - The error's marker list gains the bracket form only when the project is on the bracket convention. RED/GREEN - Revert the bracket arm -> 2 reds (phase add; insert + add-batch), the non-bracket control and both no-false-positive cases stay green. - Revert the probe threading in the merge commit -> 1 red (the probe case). - 6 new cases in the #3262 file, each with a non-bracket or no-false-positive control: fenced bracket milestone heading and bracket PHASE heading are both non-violations. Droppable: revert this commit and the merge stands on its own; the branch then ships the gap as a disclosure instead of a fix. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(changeset): narrow the enumerator claim to the directory set — per-entry rendering in progress/stats/init-manager is display-slice scope Round-7 review confirmed 3 of the 4 surfaces named by the closing claim parse each directory or heading with legacy-only patterns that live in files this PR does not touch (commands.cts:1766, commands.cts:2116, init.cts:2241). The claim now states exactly what this slice delivers: the scoped directory set. Their per-entry conversion is display work, deferred to the epic's display PR with the statusline/progress-card gates it belongs beside. * fix(#2761): de-accident the unmatched-milestone bracket fixture, re-pin to #3480's withhold contract tests/adr-612-bracket-phase-counting.test.cjs:515 ("a milestone that does NOT match STATE is not scoped in") asserted total_phases === 0. Since today's merge brought in 70b5c1a1 (#3354/#3480, already in `next`), buildStateFrontmatter withholds total_phases (omits the key, read back as null) for a milestone that is genuinely sectioned but matches no ROADMAP heading, instead of substituting a computed number — the fixture's `state json` read now returns null, failing the strictEqual(0) assertion. The original single-section fixture's 0 only ever survived by accident: hasMilestoneSectioning requires >=2 milestone-vocabulary headings to call a ROADMAP sectioned, and its isPhaseHeading helper recognizes only the legacy `Phase N:` text form — so the bracket phase heading `### [GSD.03] 09: Not this milestone` (title containing the word "milestone") miscounted as a second milestone heading, tipping hasMilestoneSectioning true and routing to the disk-count branch. With that miscount removed, the same one-section fixture reads 1 (the non-matching milestone's phase count leaking into v2.0's total) — proving the pinned 0 was never validating the scoping this test claims to exercise. Replaced the fixture with two genuine milestone sections (GSD.03, GSD.04), neither matching STATE's v2.0, with phase titles carrying no incidental vocabulary — the real #3354 shape. Re-pinned the assertion to null, matching upstream's own tested contract (tests/state- document.test.cjs, "#3354 with nothing stored, the key is omitted rather than written from the dir count"). Verified: file green 3/3 runs (104/104), full state-suite regression 771/771 green. The isPhaseHeading gap that made the old fixture accidental is a real, pre-existing, upstream-owned limitation (hasMilestoneSectioning only guards >=2-section conflation, not a single non-matching section leaking through) — not introduced by Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * chore(#2761): exempt two self-authored-fixture regexes from #3441's unbounded-quantifier rule Both sites parse the STATE.md the test itself just wrote to its own tmpdir — fixed-size fixture output, not adversarial or document-scale input. Exempted with the justification-comment pattern the tree's own tests use for this exact case (settings-integrations, copilot-install, research-agent-profiles). The sites predate the rule; #3441 landed on next this morning and this branch picked it up in the catch-up merge. * fix(#2761): fix forward two next-movement test regressions from the round-11 rebase origin/next's #3573 newly threads STATE's stored `milestone:` value into `state json`'s buildStateFrontmatter call (previously always `undefined` on that read surface). Two pre-existing PR-2 fixtures reach code paths that call never exercised before that merge: - RED (repro2 case C): a version-less, all-bracket-id ROADMAP now hits getMilestonePhaseFilter's pre-existing (unaffected by this branch) row-5 `versionResolved && !headingFound => SCOPE.UNSCOPED` rule, which withholds `progress.percent` even though the scoped total_phases/completed_phases are still correct. That row-5 rule is load-bearing for six other version-less-document pins in this same file; narrowing it broke seven of them in testing, so production code is untouched here. Reassert the test's real claim (scoping, via total_phases/completed_phases) and disclose the now-withheld percent instead of silently dropping it. - PIN (repro12 LEGACY control): a fenced-example-vs-real version heading fixture. #3573 routes this read through sliceMilestoneWindow (fence-aware) instead of the legacy anyMilestonePattern raw scan (fence-blind) this pin was disclosing as out of scope, so the fixture no longer exercises the blind path — total_phases moves from the whole-doc 4 to the correctly scoped 2. Re-pinned with an upstream-attributed comment, matching this file's existing house style for prior origin/next movements (see the sibling "PIN (G3 LEGACY control)" comment). Both are test-only fix-forwards: no production code changed. The remaining 12 failures in this file at 27363e9d0 (dropped seam commits' VERIFICATION.md naming + fixture updates) are pre-existing and deferred to the stacked follow-up per the task's own scope. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(#2761): thread phaseIdConvention explicitly at the two write-adjacent enumerator call sites (round-11 BLOCKER) listMilestonePhaseDirs' phaseIdConvention param lost its `= null` default (phase-locator.cts), so an omitted convention now means "resolve from config" instead of "explicitly not bracket" — a deliberate flip, but milestone.cts and state.cts were not in the PR-2 diff and both call the enumerator without threading it: - milestone.cts cmdMilestoneComplete (the single #3597 shared derivation feeding the stats loop, --dry-run preview, and the real archive/rename pass) now resolves phase_id_convention once and threads it explicitly, so a bracket project's `milestone complete` archives its real bracket-declared phase directories instead of silently inheriting whatever the enumerator's lazy default resolves to. - state.cts cmdStateUpdateProgress's own enumerator call threads the same resolved convention. Empirically this does not change the #3217 withhold gate (scope is assigned before headingConvention resolves in getMilestonePhaseFilter, so it's convention-independent either way) or the reported percent (already correctly threaded via computeUpdateProgressPreview -> buildStateFrontmatter); it closes a second, silently-resolved answer to the same question this file's own ONCE-and-THREAD rule (~:2300) already states as policy. - state.cts's other listMilestonePhaseDirs call site (the state-sync scope-only read, ~:4791) is left unthreaded on purpose, with an inline note explaining why: only `.scope` is consumed, and `.scope` is set before convention resolution in getMilestonePhaseFilter, so it cannot disagree with a threaded convention. Both enumerated sets are pinned by new tests (round-11 BLOCKER block in tests/adr-612-bracket-phase-counting.test.cjs), including a mutation-style regression check on the milestone.cts fix (forcing the un-threaded default back on makes the pinned test fail, catching a regression to the pass-all-degrade legacy reading). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(#2761): correct the changeset's false archival claim and amend ADR-612 for the round-11 M2(2) split scope The changeset (.changeset/2761-bracket-read-tolerance.md) asserted "The archival and milestone-completion paths are unchanged" — false: both paths reach the widened enumerator, and this PR now threads their convention explicitly (previous commit). Replaced the closing paragraph with an accurate description of what changes for a bracket project at those two call sites, and notes both enumerated sets are pinned by tests. ADR-612 (docs/adr/612-bracket-phase-id-convention.md) amended per M2(2): the 2026-08-03 PR-2/PR-4 boundary proposal is added in-body (PROPOSED, not stamped — mechanics per docs/contributor-standards.md:143 reserve ADR ratification to maintainers), rescoped to what actually ships in PR-2 (#2761) now that the round-11 M1 split moved the completion-seam threading (isPhaseArtifact/scopeToPhase, phase-id.cts:964-1090) out into a separate, stacked follow-up PR referenced generically via epic #612: - state.cts read-tolerance (both total_phases derivations, the #1514 retirement filter) moves into PR-2's row, alongside milestone.cts, reflecting the round-11 fix above. - the write-observability point is restated in terms of what actually ships: explicit threading at two named call sites, pinned by tests, rather than silent inheritance. - the completion-seam threading is named and explicitly excluded from PR-2's scope, with a new ratify item (5) and a Negative consequence bullet covering the sequencing cost. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(#2761): repair round-11 response gaps — disk-side sentinel bug, test-fixture bug, scanMilestonePhaseIds caller drift Four independently-verified gaps in the round-11 repair response: 1. isSentinelPhaseId (src/phase-id.cts) treated a bare, untagged phase directory under phase_id_convention: "bracket" (`0-bootstrap`, no `{CODE}.{MM}-` prefix) as sentinel milestone 0 by falling through to the legacy leading-int rule when the bracket-tag match failed. This silently dropped a real, on-disk, milestone-declared phase directory from `listMilestonePhaseDirs` (phase-locator.cts:424, the only unguarded call site) and undercounted completed_phases/percent. Mirrors the carve-out already present on both heading-side counters (state.cts's countRoadmapPhaseHeadings guards its bare-0 exclusion with `bracketId &&`; roadmap-parser.cts's scanMilestonePhaseIds composes the bare-token rule as 999-only) — under bracket convention, milestone 0 is expressed only via an explicit bracket tag, so an untagged leading 0 is a real phase token. 2. tests/adr-612-bracket-phase-counting.test.cjs's writeProject fixture hardcoded `01-VERIFICATION.md` for every "complete" phase dir regardless of the dir's real phase token. Under legacy convention this file already correctly failed #3511's strict isPhaseArtifact match for any dir other than phase 01 (the fixture never modeled what it claimed to); under bracket convention the pre-existing ambiguity fail-safe admitted it regardless. The two readings' disagreement was mistaken for a missing completion-seam threading (isPhaseArtifact/scopeToPhase convention awareness, correctly split out to the stacked #3644 per round-11's M1). Replaced the hardcoded name with verificationNameFor(dir), deriving the real per-phase filename from the production normalizePhaseName the same way cmdScaffold does — the 7 failing "flat-legacy-twin" / CHARACTERIZATION assertions pass on #2867's own code with no seam threading required, and the genuine seam-dependent cross-phase-stray-exclusion test the fixture fix would otherwise have hidden lives on the stacked branch instead. 3. tests/roadmap-parser.test.cjs's two #3577 tests still called scanMilestonePhaseIds with the old single-Set return shape; this PR changed it to `{ ids, qualifiedIds }` for every other caller but missed these two, which don't touch #2761/bracket code at all. TypeErrors at runtime, not silently-wrong assertions. Updated both call sites. 4. .changeset/2761-bracket-read-tolerance.md gains a paragraph disclosing fix 1 above, so the changeset stays accurate to what actually ships (the round-11 BLOCKER was exactly this changeset going stale once). Verified: tests/adr-612-bracket-phase-counting.test.cjs + tests/continuation-grammar-parity.test.cjs + tests/roadmap-parser.test.cjs = 354/354. adr-612-{coherence,grammar,heading-selection,read-tolerance, selection.property}.test.cjs + collision-characterization = 287/287 (CONFIRMED-CLEAN set, unaffected). Full unfiltered suite run separately. PR #3643 (round-11's M1 split, opened draft per that round's explicit requirement) was auto-closed by this repo's own draft-PR policy 11 seconds after opening — draft PRs are unconditionally closed here. Reopened as non-draft #3644 (same branch, same commits, DO NOT MERGE / stacked-on-#2867 marker in the body, enhancement template) since the repo's own bot confirms non-draft contributor PRs are tolerated even off-template. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(#2761): narrow the state-update-progress pin claim to what mutation testing actually proved, add the test that covers the rest Round-11 BLOCKER response gap (verified, not a guess): the changeset and ADR-612 amendment point 2 both claimed the round-11 tests pin `cmdStateUpdateProgress` so "a future change to the enumerator's default cannot silently move ... what state update-progress reports without failing a test." Mutation testing disproves this. Reverting BOTH the state.cts explicit `phaseIdConvention` thread AND simulating the phase-locator.cts pre-#612 hardcoded-null default (`phaseIdConvention: null` at that one call site) leaves the existing PIN test ("writes a real percent for a bracket-scoped milestone") green, because that percent comes from `computeUpdateProgressPreview` -> `buildStateFrontmatter`, a separately and already-correctly-threaded derivation the state.cts inline comment at ~:965 already candidly documents. What the reverted thread DOES change, empirically, is `phaseDirs`/`totalPlans` — the enumerated `.value` this call site feeds into the #3233 zero-plans no-op gate a few lines below. That is the one place a regression at this call site is observable in the command's output. Added a test that pins exactly that: a bracket milestone whose declared phases carry no plans on disk, alongside a decoy directory that plainly does not belong to the milestone (no bracket tag, no phase token) but does have a plan. Correctly scoped, the decoy is excluded and the #3233 no-op fires (`updated: false`). Degraded to the pass-all legacy reading, the decoy is swept in, `totalPlans` flips nonzero, and the no-op never fires (`updated: true`). Mutation-tested against both scenarios: - Reverting ONLY the state.cts explicit thread (falls back to `undefined`, which `getMilestonePhaseFilter` resolves via the identical `resolvePhaseIdConvention(cwd, undefined)` call the explicit thread also makes): new test stays green — confirms the single-hunk thread really is pure single-derivation hygiene, exactly as the existing inline comment claims, for this test too. - Forcing `phaseIdConvention: null` at that call site (the combined-revert scenario the round-11 mutation testing actually exercised): new test FAILS (`updated: true, percent: 0` instead of the expected `updated: false`). Restoring the real code makes it pass again. Narrowed the changeset and ADR-612 point 2 prose to match: `cmdMilestoneComplete`'s enumerated set is pinned against a pass-all-degrade regression (genuine, already verified in round 11); `cmdStateUpdateProgress`'s own call site is now pinned against the #3233 zero-plans no-op specifically, not against the reported percent, which the prose no longer claims. Added a one-line pointer to the new test in the state.cts inline comment. No production behavior changes — test and documentation only. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * docs(#2761): reconcile ADR PR-2 module map * fix(#2761): restore #3639's dir-aware W007 sentinel exclusion lost in the rebase replay The rebase replayed this file's pre-#3639 patch over next, reverting the isSentinelPhaseId(token) -> isSentinelPhaseDir(dirName) fix: the extracted token is milestone-stripped, so a bracket sentinel (GSD.999-07-icebox, GSD.00-01-backlog) was invisible to the id predicate and false-fired W007. Restores upstream's call and comment verbatim; the branch's convention-aware token remains for the diagnostic message only. Caught by next's own #3639 regression tests (CI shard 2). Local: the file's 18/18, health-diagnostic-rules 165/165, full npm test exit 0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MeAsZNfhiUQioFPA4ygEGS * docs(#2761): ratify scope and correct surface claims * test(#2761): strengthen legacy selection and drift claims * docs(#2761): correct the enumerator claim, scope list, and ratification receipt Three documentation corrections, none touching production code. The changeset claimed the shared phase-directory enumerator "now defaults its convention argument to 'not yet resolved' rather than 'resolved, and not bracket'". That is false: `phase-locator.cts:375` still destructures `phaseIdConvention = null`, and the lazy resolve-from-config fires only on `undefined` (`roadmap-parser.cts:941`, `:1928` — whose own comment records that "explicit null still means 'resolved and non-bracket'"). Measured: only 4 of 17 `listMilestonePhaseDirs` call sites thread a resolved convention (`milestone complete` and `state`'s three). The changeset went on to name `progress`, `stats`, `phase list` and the init manager view as now receiving a correctly scoped set — those are precisely callers that omit it. Replaced with what the code does, and the deferral stated plainly. The ADR's PR-2 row omitted `scripts/lint-phase-id-drift.cjs` (+141/-14) and `scripts/lint-phase-enumeration-drift.cjs`, both changed by this PR. An under-claim rather than an over-claim, but the row is the epic's scope-of-record. Ratify item 5 asserted maintainer ratification while citing only the review that raised the question. It now cites the review that granted it (#2867 review `5012940978`, 2026-08-24) and quotes its terms, so the claim carries its receipt. Found by an adversarial review pass over the round-12 diff. (#2761) * fix(#2761): drop the no-op --json that strict argv now rejects Surfaced by the rebase onto next, not by a change in this PR's subject. #3884 ("failure is a value — strict argv", e20744eac) made an unrecognized flag a hard error: `state validate --json` now exits 1 with `unknown flag "--json"; accepted: --strict` on stderr and EMPTY stdout, where the token was previously accepted and ignored. `state validate` never had a `--json` flag — JSON is its only output shape — so the argument was a silent no-op from the start. The helper parsed that empty stdout, so all five subtests in the "state validate resolves bracket phase DIRECTORIES" suite failed identically with `SyntaxError: Unexpected end of JSON input` at the JSON.parse, masking what they actually assert. Dropping the token restores the same envelope the helper already parsed. No assertion changes. Verified against the fixture the suite builds: exit 0, and the output carries the S005 plan-count warning the drift assertions require with no S004 phase-directory warning — i.e. the bracket directory resolves, which is the behaviour these tests exist to pin. 94/94 in the file. * fix(#2761): exempt the phase-counting suite from the docs-guard lane Surfaced by the rebase onto next. #3753 (107eb8c1d) added lint-docs-guard-registration, which requires every test file that reads a docs/ path to be either registered in the docs-guard lane or carry an explicit marker. It flags adr-612-bracket-phase-counting.test.cjs, which reads no docs/ path at all. The file's only docs/ occurrence is the ADR-612 Decision 1 citation in a line comment; every read call it makes targets a tmpdir .planning fixture. It trips Detector 3, whose DOCS_TEMPLATE_LITERAL_RE sees an odd prose backtick in the comment block above that citation as opening a template literal and reads the span between them — citation included — as a docs/ path expression. That detector documents this trade in its own header: it favours recall, and says a false positive costs one docs-guard-exempt marker with a reason. The baseline records the same class ("comment-only mentions") for 46 of its entries. Registration was the wrong side of the trade here: it would run this suite in the docs-guard lane on docs/ changes whose content it never reads. Three pieces, matching what the gate requires and what its 54 existing entries already do: - the marker in the file's header window, written without backticks so it cannot itself disturb the parity tracking findExemption does; - the basename in DOCS_GUARD_EXEMPT_BASELINE, since the ratchet fails a new marker until the baseline is deliberately updated — the reviewable diff is the point; - the FIX 3 per-file fingerprint, derived with the lint's own extractDocsPathReferences rather than retyped, so the exemption fails loudly if the set of docs/ paths this file mentions ever changes. Gates: lint-docs-guard-registration 0 violations, ci-docs-guard-registry 51/51. * docs(#2761): correct the bare-0 comment and state what opting into bracket costs Round-13 review items Minor 2 and Minor 3, both still live on the previous head. Minor 2 — src/phase-id.cts. The comment block claimed "Bare `0` is admitted alongside it because a 0.x sentinel is a legitimate identity that predates padding", which contradicted both the shipped constant and its own next paragraph. BRACKET_CANONICAL_NUMERIC_SOURCE is `(?:[1-9]\d{2,}|\d{2})`; measured against it, `0` is rejected while `00`, `05`, `99`, `100` and `999` are admitted. The paragraph four lines below already recorded the removal ("the earlier `(?:\d{2,}|0)` ... admitted ... a bare `0` that pad2 never produces"), so the block asserted and denied the same fact. The stale sentence is replaced with what ships: `00` is the backlog sentinel's canonical padded identity, `\d{2}` already covers it, and nothing needs the unpadded spelling. No behaviour change — the constant is untouched. Minor 3 — docs/CONFIGURATION.md. The phase_id_convention row described the read-path widening but never said what a repo GIVES UP by opting in. Added: on a bracket repo a heading whose bracket is followed directly by a digit is read as a phase heading, so `### [RFC.2119] 5:`, `### [v1.0] 2024:` and `### [ADR.612] 3:` — legal prose headings under any other convention — are claimed as phases and move phase_count, total_phases and W006. Those three shapes are the ones phase-id.cts's own selector comment names as the reason the widened read is selected at construction time from this value rather than applied everywhere; the row now carries that trade instead of only its upside. Gates: tsc --noEmit exit 0, npm run lint:ci exit 0, npm run test:unit 33890/33891 with the single failure being emitted-attribution's base drift against a next that moved after the rebase (133/133 against the rebase base; this push re-bases onto the current tip, which resolves it). --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-08-31 14:03:48 -04:00

Also addresses review majors/minors: delete readConfigBaseBranch and readConfigProtectedBranches (dead in production, only self-tested); --is-protected now fails closed (reports protected) instead of silently answering false when the base branch can't be verified; trim configured protected-branch names; fix HOME-without-USERPROFILE vacuous isolation on Windows; correct the drift-ack's byte accounting. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01S44stkuQbhD3jTCtKzte5N * test(#3648): add failing legacy-key hoist safety coverage Round-2 review found normalizeLegacyKeys block 5 records a normalization carrying the DISCARDED flat value on the canonical-wins branch. Probing that turned up a second, unreported defect in the same helper shape: blocks 1, 2 and 5 all spread result['git'] / result['planning'] with no object guard, so a config whose section key holds a string is spread into index keys — {"git":"main","base_branch":"release"} -> {"git":{"0":"m","1":"a","2":"i","3":"n","base_branch":"release"}} The resolved value is accidentally still correct, so nothing fails and no diagnostic fires. But normalizations.length > 0 sets configDirty, and config-loader then serializes that shape back into the user's config.json — a read that silently corrupts config. The deleted #3057 W3 suite covered {"git":"main","base_branch":"release"} explicitly; this is the input it would have caught. Covers both defects across blocks 1 and 5, with object/array/null negative controls that must stay green in both phases, and a fast-check property over arbitrary `git` values. * test(#3648): pin fail-closed handling of malformed protected_branches Replaces the test that pinned the fail-OPEN behaviour. The old assertion — ['develop', 42] yields isProtected === false for 'develop' — locked in the exact failure #3552 exists to close: config-set validation is bypassable by a direct edit of .planning/config.json, so a user who believes 'develop' is protected got a silent false and no warning. It was also inconsistent with the fail-CLOSED direction twelve lines away, where an unverified base reports protected and writes a diagnostic. A protection predicate must not have two opposite failure directions depending on which input is bad (#3648 review Blocker 3). New coverage: a bad element drops only itself, a non-array contributes no names, an empty list is well-formed rather than malformed, and --is-protected surfaces the rejection. Both negative controls — a clean list reports nothing rejected and writes no diagnostic — must stay green in either phase, so the reject channel cannot fire unconditionally. * fix(#3648): drop only invalid protected_branches and report them Partition git.protected_branches instead of discarding the whole list on one bad element, and carry the rejections out through ProtectedBranchStatus so --is-protected can name them on stderr. Valid names keep protecting; the user finds out the rest were ignored. A non-array value still contributes no names — a bare string is not a list of branch names — but is now reported rather than swallowed. An empty array stays silent: declaring no extra protected branches is a valid choice, not a misconfiguration. writeDiagnostic is hoisted out of the unverified-base branch since both arms now use it. * test(#3648): prove the predicate diagnostic survives both call sites The workflow bash stub now emits a stderr diagnostic the way the real command does, which is what makes a swallowed `2>/dev/null` visible to a test — previously the stub was silent on stderr, so discarding it changed no observable behaviour and the call sites could drop the explanation undetected. Adds the Minor 2 binding check as well: ship must expose the predicate result as IS_PROTECTED rather than only echoing a warning, asserted by running the extracted bash and reading the bound value, not by grepping the workflow source. Both tests carry opposite-outcome controls — an empty diagnostic must leave the text absent, and a false predicate must bind false. * fix(#3648): surface the predicate diagnostic and bind ship's result Drop `2>/dev/null` from the --is-protected call at both call sites. The fail-closed explanation and the new rejected-entry warning both go to stderr, so discarding it left the user with a bare "protected branch" warning on a branch that is not protected and no way to tell a real match from a degraded-git guess. `git branch --show-current` keeps its own redirect — that one is genuine noise. ship.md binds IS_PROTECTED and its prose now branches on the variable, so the following steps have evaluable state instead of having to infer it from warning text in tool output. execute-phase.md byte accounting refreshed: 92326 -> 92645, net growth 319 bytes (was 331 before the redirect came out). Baseline re-verified against the current rebase base by blob id; the ceiling check passes with 755 bytes of margin. * test(#3648): restore negative space for the readFile config seam The #3057 W3 suite was deleted with readConfigBaseBranch, but every arm it pinned survives verbatim in readEffectiveGitConfig's readFile branch — the JSON.parse catch, the non-object guard, the git-section object guard, .trim() and blank-string rejection — and the four surviving readFile injections were positive-path only. protected_branches was never driven through this seam at all. Restores nine cases against the seam, including protected_branches partitioning, plus a control proving loadConfig still wins when both seams are supplied. Records honestly what the suite pins. Mutating the built lib shows .trim() is KILLED, while the non-object guard and the blank-string rejection SURVIVE — both are unreachable through this entry point for the same reasons the deleted suite documented against its own equivalents: a JSON-parsed non-object carries no relevant own-property either way, and a blank value is rejected a second time downstream by the resolver's truthiness check. They stay as defence-in-depth and are labelled known-unkillable rather than left looking like coverage this suite does not provide. * test(#3648): distinguish detached HEAD from a missing branch argument `args[1] ?? ''` collapsed two different situations into one: a detached HEAD, where `git branch --show-current` legitimately prints nothing, and the flag being called with no argument at all. Both answered false, so the right outcome arrived by an unintentional path and a caller bug was indistinguishable from normal operation. Asserts the detached case stays silent and the missing-argument case reports, with a control that the two diagnostics differ. * fix(#3648): report a missing --is-protected branch argument Answer false either way, but say so when the flag arrives with no argument. A detached HEAD passes an explicit empty string and stays silent, since that is a normal state rather than a misconfiguration. * docs(#3648): state exact-name matching and per-entry rejection isProtected is exact string equality, so a git-flow project must enumerate every release/* and hotfix/* by name. #3552 only asked for an integration-branch field, so the implementation satisfies the letter of the issue while leaving its git-flow motivation partly unserved — say so where users will meet it rather than leaving them to discover it. Also documents the Blocker 3 behaviour change: an invalid entry is ignored with a warning naming it and the remaining names still apply. Both statements land in docs/CONFIGURATION.md and gsd-core/references/planning-config.md, and the config-field-docs parity test asserts each in both so the two cannot drift. * refactor(#3648): extract isValidProtectedBranches for cross-surface pinning The `git.protected_branches` check inside `cmdConfigSet` and the resolver's per-entry filter in `git-base-branch.cts` are deliberately different shapes — all-or-nothing on write, per-entry on read, so a hand-edited config.json cannot fail the guard open. Nothing structural keeps their two definitions of "usable branch name" in step. Lifting the write-side check into a named, exported predicate lets a property test ask both surfaces about the same value and assert they agree, which is the fast-check gap the round-2 review flagged. No behaviour change: the predicate is the same expression, called from the same place. * fix(#3648): stop --is-protected rewriting the config it is asking about `gsd_run query git.base-branch --is-protected` runs on every execute-phase and every ship. It resolved config through `loadConfig`, whose normalize-then-write path rewrites `.planning/config.json` whenever any legacy key normalizes — so a boolean question was silently editing the user's checked-in config. This PR had widened the trigger by adding a fifth normalization block (top-level `base_branch` -> `git.base_branch`), making it fire for exactly the projects the feature targets. `loadConfigResolved` gains `options.persist` (opt-OUT, default true): resolution is unchanged, only the two write-back side effects are suppressed. The predicate passes `persist: false`; the ~30 other callers are untouched, so a legacy config is still migrated by ordinary use. Asserted on BYTES rather than parsed shape, because the rewrite reorders keys and reflows whitespace even when the values are equivalent. Three tests, each with its own control: the end-to-end CLI leaves the file byte-identical while still answering `true` from the legacy key (proving the config WAS read); an ordinary persisting load of the same fixture DOES change the bytes (proving the fixture is live rather than inert); and `persist:false` vs default over one directory returns deep-equal config while differing on the write. Reverting the one-line `persist: false` fails the first of those and only that one. Also from the review: - `readEffectiveGitConfig`'s comment claimed the readFile branch routed "through the same precedence authority production uses". It does not, and cannot — it reproduces two of production's steps over a single file. The comment now names what the seam covers and what it does NOT (root/workstream deep merge, builtin and global defaults, federated merge), and the seam now applies production's flat-then-nested lookup so it stops disagreeing about a surviving flat key. - The missing-argument diagnostic promised "answering false", which the fail-closed guard on the same call can contradict by printing `true`. It now states what it did with the argument and leaves the answer to stdout. * test(#3648): re-pin block 5 on #3760's refusal contract #3767 landed on next while this PR was in review and fixed the non-object config-section defect properly: a present-but-non-object section now BLOCKS its own migration — value preserved, no Normalization pushed, refusal reported via `skipped[]` — rather than being rebuilt from a plain-object view. That supersedes this branch's round-2 `hoistLegacyKey`, which prevented the character-key spread but still dropped the section value silently, and which the round-3 review correctly called out as destruction in place of corruption. The rebase drops that commit and routes block 5 through the upstream helper. This file's tests asserted the superseded design, so they are rewritten to pin block 5 — `base_branch` -> `git.base_branch`, which did not exist when #3760's suite was written — against the contract that now governs it: ordinary hoist into an absent/null/object section, canonical-nested-wins, and refusal for each of string/number/boolean/array sections with the exact `skipped` entry. Two controls keep it from passing vacuously: the refusal must be scoped to block 5 (an unrelated block still normalizes in the same call), and a property over arbitrary `git` values asserts hoist and refusal are exhaustive AND mutually exclusive per key, that a refusal leaves both the section and the legacy key untouched, and that a hoist manufactures no index key the input did not carry. * docs(#3648): correct the Git Query and Config Loader module contracts CONTEXT.md's Git Query Module still described base-branch tier 1 as a direct `.planning/config.json` read. Since this PR it is the EFFECTIVE configuration resolved by the Config Loader — a materially different authority, carrying the root/workstream deep merge, flat-then-nested lookup and builtin/federated defaults. The `--is-protected` predicate, `git.protected_branches`, and the two invariants that distinguish the predicate from the plain query (fails closed on an unverified base; must not write) were undocumented entirely. The Config Loader entry now states that loading is not side-effect-free by default and documents `options.persist`. docs/INVENTORY.md's `git-base-branch.cjs` row carried the same stale ladder and no mention of the predicate. `node scripts/gen-inventory-manifest.cjs --write` was run and produced no diff: the manifest indexes roster NAMES, not row prose, so a description edit cannot move it. Also closes the global-defaults minor: `git.protected_branches` is inert in `~/.gsd/defaults.json`, but so is every other `git.*` key — no branch-policy key appears in `_globalBaseCfg` or `GLOBAL_DEFAULTS_RESOLUTION_KEYS`. That is section-wide and predates this PR, so the fix is to state the scope where users meet it rather than to quietly extend the resolution set for two new keys. * fix(#3648): close four defects found by the round-4 external review Two external reviewers (codex, antigravity/Gemini 3.1 Pro) were run adversarially against this branch. Four findings reproduced against source; each is fixed with a failing-first test and a control, and each fix was verified by reverting it and watching exactly the intended test fail. 1. `persist:false` was DROPPED by the workstream fallback (codex). Blocker 1 was only half closed. `loadConfigResolved` re-enters itself with a bare `{ workstream: null }` when a workstream has no config.json of its own, and that literal discarded every other option — so the recursive pass ran at the DEFAULT persistence and rewrote the ROOT config. Reproduced: with GSD_WORKSTREAM=alpha and a legacy flat `base_branch`, `--is-protected` rewrote `.planning/config.json` despite `persist:false`. Both recursions now forward `options` and override only `workstream`; the explicit override still wins the hasOwnProperty check, so spreading cannot let `workstreamContext` reintroduce a workstream. 2. Both workflow call sites failed OPEN, and aborted under `set -e` (both reviewers, independently). `IS_PROTECTED=$(gsd_run ...)` yields an empty string when the query fails, so `[ "$X" = true ]` was simply false: no warning, no trace — a silent hole in the guard whose only job is to warn. The bare assignment also aborted the step under `set -e`. Both sites now degrade VISIBLY: `|| IS_PROTECTED=""`, then an explicit empty-string arm that says the check did not run. Deliberately not fail-closed — claiming "protected" on no evidence would warn on every branch whenever gsd-tools is unavailable. 3. `isValidProtectedBranches` and the resolver disagreed on a sparse array (antigravity). `.every()` skips holes; the resolver's `for...of` yields `undefined` for them, so `["main", , "develop"]` was accepted by config-set and rejected by the resolver. The cross-surface property passed only because `fc.array` cannot generate a hole. The predicate now indexes, and the generator punches holes so that axis is actually falsifiable. JSON cannot express a hole, so this is unreachable in production — but two definitions of one predicate must not contradict each other. 4. A top-level `protected_branches` silently outranked `git.protected_branches` (antigravity). Routing the key through `get(key, {section, field})` gave it flat-then-nested precedence, which is back-compat for keys `normalizeLegacyKeys` migrates. `protected_branches` is new in #3552 and has no legacy form, so that invented an undocumented alias. It now resolves nested-only through a new `getNested`, in production and in the test seam. `base_branch` keeps flat-then-nested — it HAS a legacy spelling that #3760's refusal path can leave behind — and a control pins that distinction. Also narrows a CONTEXT.md claim this round introduced. The predicate fails closed only when a git query TIMED OUT or could not be spawned (#3057 B4's `verified`); a git command that runs and exits non-zero counts as a clean negative, so a cwd that is not a repository answers `false`, not `true`. Verified pre-existing on next @ 738f42f4, so the documentation was over-claiming rather than the code regressing — but an over-broad contract is exactly what the module docs must not carry. Both workflow byte figures re-derived after the call-site change: execute-phase.md 92356 -> 92865 (+509), ship.md 36784 -> 37227 (+443). * test(#3648): pin git config read parity * docs(#3648): document git query contracts * fix(#3648): expose protected branch default * test(#3648): snapshot planning tree for read-only query * test(#3648): pin planning snapshot stray-write detection * fix(#3648): resolve merge conflict from #3078's ack-fragment sweep next swept the fully-spent 2818/3003 ack fragments this branch had appended to (#3078, a84f7563). Rebased onto upstream/next and took the deletions on both, then moved the #3552 append into a new fragment of its own. Rebasing onto the current base also left execute-phase.md only 34 bytes under the frozen ADR-857 Phase 6 margin ceiling (93400 bytes) — intervening next PRs consumed the rest while this PR was in review. Extracted the "none" arm's protected-branch-warning bash block into gsd-core/workflows/execute-phase/steps/protected-branch.md (content unchanged, matching the existing steps/ extraction pattern used elsewhere in this file) so the inline growth is a one-line pointer instead of the full block. 93366 -> 93385 bytes (+19), 15 bytes inside the ceiling. * fix(#3648): drop stale ack entry for the new step file The extracted execute-phase/steps/protected-branch.md needed no acknowledgment of its own — the differential-attribution check flagged the entry as stale once the build ran, so removed it and kept the two growth entries (execute-phase.md, ship.md) that actually needed one. * fix(#3648): follow the step-file reference in the bash-extraction test helper extractProtectedBranchWarningBash() read the "none" arm's bash block directly out of execute-phase.md. That block now lives in execute-phase/steps/protected-branch.md (byte-ceiling extraction); the helper follows the step-file reference and extracts from there when no inline block is found, so the three execute-phase tests that execute this bash for real keep exercising the actual behavior. * fix(#3648): regenerate INVENTORY-MANIFEST.json and satisfy the CRLF-fragile lint rule - gen-inventory-manifest.cjs --write to pick up the new execute-phase/steps/protected-branch.md entry (already covered by docs/INVENTORY.md's generic workflow_steps wildcard row, so no INVENTORY.md edit is needed). - Reworked the step-file-reference lookup in extractProtectedBranchWarningBash() to avoid a bare-\n regex split on file content (local/no-crlf-fragile-split), using the same line-array scan the function already uses elsewhere. * fix(#3648): regenerate golden install-tree fixtures for the new step file npm run gen:install-tree, adding gsd-core/workflows/execute-phase/ steps/protected-branch.md to all 19 runtime install-tree fixtures. CI's tests/golden-install-tree.test.cjs caught this on push — I'd verified the differential-attribution and INVENTORY-MANIFEST checks but missed this separate golden-fixture check for the new file. * fix(#3648): add the canonical gsd_run preamble to the new step file CI's runtime-launcher-parity suite requires exactly one canonical resolver preamble in every workflow .md that calls gsd_run. The inline "none"-arm block never needed one (execute-phase.md already carried a preamble elsewhere in the same file), but the extracted execute-phase/steps/protected-branch.md is now its own file with no preamble of its own. Ran node scripts/sync-runtime-launcher.cjs to insert it (execute-phase.md itself is untouched — still 93385 bytes, inside the ADR-857 ceiling). That preamble defines its own gsd_run(), which shadows the mock tests/git-base-branch.test.cjs injects for the three #3648 tests that execute this bash for real — without stripping it, those tests reached the real gsd-tools.cjs on the machine running them instead of the test's fixture. Preamble correctness is already covered by tests/runtime-launcher-parity.test.cjs, so extractProtectedBranchWarningBash() now strips the preamble line before handing the block to the harness; it only needs to exercise the #3552 warning logic. * fix(#3552): address PR 3648 review feedback on protected branch warnings - Fix execute-phase handle_branching branching_strategy=none instruction to "Read and execute execute-phase/steps/protected-branch.md" - Use io.error(..., ERROR_REASON.USAGE) for cmdGitBaseBranch usage errors - Align git.protected_branches schema default to (none) without fallback [] - Relocate CONTEXT.md forward-referencing sentence into module body - Sanitize control and ANSI characters in renderRejected diagnostics - Clean up out-of-scope whitespace hunks in gsd-tools.cjs Emitted-Drift-Ack-Growth: execute-phase.md — #3552: execute-phase handle_branching adds a pointer to execute-phase/steps/protected-branch.md for branching_strategy=none so the protected-branch check executes while keeping execute-phase.md within the ADR-857 Phase 6 margin ceiling (93400 bytes). 93392 bytes, 8 bytes inside the ceiling. Emitted-Drift-Ack-Growth: ship.md — #3552: ship preflight step 3 now asks the same typed git.base-branch --is-protected predicate as execute-phase, binding IS_PROTECTED and warning without refusing execution or blocking the branching_strategy=none feature-branch offer; it degrades visibly (rather than silently reading an empty result as "not protected") when the query itself fails to run. 36841 bytes, well inside the XL cap (98304, tests/workflow-size-budget.test.cjs). --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> Co-authored-by: Tom Boucher <trekkie@nomorestars.com>	2026-08-29 17:00:52 -04:00

Added the same grammar (as a literal regex, documented as intentionally not shared across the .cts/.cjs build boundary) plus a parity test asserting the two surfaces agree across a valid/invalid trackerPrefix table. 3. task-command-router.cts's routeResolveContent path-traversal guard on --plan had zero test coverage. Added a test exercising a ../../../etc/passwit-shaped path and asserting the USAGE rejection names the offending path. * fix(#3970): sanitize resolver diagnostics and cap resolver timeoutMs Two findings caught by an isolated security-review pass on the task content resolution seam: - ResolverFailedError/ResolverMalformedOutputError embedded raw, unsanitized subprocess stderr/stdout (attacker/model-influenced via the tracker-id argv token) into .message. A hostile or buggy resolver could smuggle a newline plus a forged "Error: " line, or terminal escape sequences, into a diagnostic io.cjs's error() writes verbatim to stderr. Fixed at the constructor (task-content-resolution.cts) via io.cjs's existing formatDiagnosticToken(), so every caller of resolveTaskContent gets a safe .message by construction. - capability-validator.cjs's validateTaskContentResolverFields had no upper bound on taskContentResolver.invoke.timeoutMs, letting a manifest declare an effectively unbounded value and defeat the "bounded subprocess" design intent. Added a 120000ms ceiling specific to this field, without touching the shared isPositiveIntegerMs() helper (still used unbounded by the reviewer lane's timeoutFloorMs and probe timeoutMs). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3970): fix gsd-test failures — stale prose allowlist line and stderr-vs-message assertion gsd-test (remote dockerized matrix) came back red with 5 failures on this PR; all five are real defects, fixed here. - tests/no-bare-gsd-tools-command-position.test.cjs: PROSE_ALLOWLIST's execute-plan.md entry pointed at line 415, which ffc190df4's checkpoint-exclusion caveat (added near line 221) shifted down by one line. The actual "validated downstream by gsd-tools uat classify-coverage" descriptive mention now sits at line 416. Updated the allowlist entry's line number to match. - tests/task-command-router-resolve-content.test.cjs: the path-traversal test asserted the outside-project-scope diagnostic against the thrown ExitError's own .message. io.cts's error() (ADR-3889) writes its human-readable message to fd 2 via writeAllSync and then throws a bare `new ExitError(1)` with no message argument — by design, so the exception carries no duplicate text and the thrown ExitError's message defaults to "process exit 1" (cli-exit.cts's ExitError constructor). Root cause was the test, not the source: task-command-router.cjs's outside-project-scope rejection already calls error() correctly and the diagnostic text is genuinely emitted, just on fd 2, not on the exception. Fixed the test to capture fd-2 writes (mirroring tests/estimate-calibrate.test.cjs's runCalibrateExpectError and this same file's own captureStdout for fd 1) and assert against the captured stderr text instead of err.message. This was masked locally because a manual `node -e` sanity check that only inspects the caught exception's .message cannot see what the real node:test run actually failed on. Emitted-Drift-Ack-Growth: execute-plan.md — adds the ADR-3646 task-content-resolution bullet and checkpoint-exclusion caveat to the per-task execute loop; a real behavioral prose addition, not incidental bloat.

The two rows that carry the design's load: - merge-base semantics. The range is $(git merge-base base HEAD)..HEAD, not base..HEAD, because changedPaths comes from `git diff base...HEAD` (three dot). Two-dot would let the ack set and the change set disagree about which commits are this PR's. The fixture forks a topic branch, puts a trailer on each side, and asserts only the topic-side trailer is in range. - fail-closed on an uncomputable range. With fragments a depth-1 checkout passes VACUOUSLY, every fragment reading as brand-new. With trailers the range cannot be computed at all, and returning an empty set would silently disarm the gate, so it must throw. The fixture builds a genuine shallow clone rather than simulating one. Also covers the self-inflicted case: this change's own documentation quotes the trailer syntax, so an example landing at the end of a commit message would arm a live acknowledgment keyed on the literal placeholder text. Keys carrying angle brackets or whitespace are rejected. Authored per the phase artifacts 40-design.md and 50-test-matrix.md. Not yet run on the remote runner — this commit exists to be tested. Refs #3942 * chore(#3942): move the emitted-drift ack to a commit trailer Implements ADR-3942, superseding ADR-2719 section 3 and its #2789 amendment. Sections 1, 2 and 4-7 are retained: the conservation law is unchanged, only the storage of its escape hatch moved off the working tree. An acknowledgment explains one PR's ripple, and the moment that PR merges the ripple is in the base, so it can never clear anything again. It was stored in permanent shared state anyway, and every consequence of that mismatch had to be built and then maintained. The chain is #2789 -> #2914 -> #3078 -> #3842 -> #3823 -> #3875, each fix generating the next defect, ending in a scheduled sweeper whose own first PR could not merge itself. Added parseAckTrailers + renderAckTrailer (pure) and readAckTrailers (IO shell), reading Emitted-Drift-Ack-Hash: / Emitted-Drift-Ack-Growth: trailers over the merge-base range. tests/emitted-ack-trailer.test.cjs, 37 cases, written failing-first and confirmed red before any of this existed. Changed diffEmitted takes two structurally distinct key-space maps instead of one shared paths map. That closes a latent defect: the spaces were separated by convention only, so a growth key satisfied a hash lookup by naming coincidence. staleAcks now reports which space a key was declared in. REMEDIATION teaches the trailer, per space, with its example rendered through renderAckTrailer so the taught grammar cannot drift from what the parser accepts. Removed the sweep workflow, the guard-no-ack-on-next job, the standalone linter and its lint:ci entry, the fragment directory and its three spent fragments, the legacy single-file union, and the baseAck/spentAcks mechanism -- spentness is now structural, not computed. Two range properties carry the design and are pinned by tests rather than asserted: the range is merge-base scoped, matching git diff base...HEAD, so an already-merged trailer is out of range by construction; and an uncomputable range throws instead of reading as zero acknowledgments, which is the inverse of the fragment guard's vacuous pass. Three deliberate observable changes, each disclosed in the changeset: the unread runtime field is gone, the legacy file is no longer read, and cross-space excusal no longer works. Ten open PRs carry fragments and will meet a modify/delete conflict. Measured before landing and accepted deliberately; the one-line migration is in the PR body. Verified: lint:ci exit 0. Remote runner to follow on this exact sha. Refs #3942 * fix(#3942): silent trailer collapse, lost coverage, and an unbounded cap Six findings from the orthogonal review round, all fixed in place. BLOCKER -- two trailers of the same name on one commit collapsed silently. readAckTrailers built `separator=1d` where git needs `separator=%x1d`: the `separator=` value inside a %(trailers:...) placeholder is itself a pretty-format string, so the bare hex was emitted as two literal characters and the split on \x1d never matched. Two same-name trailers therefore joined into one value with errors empty -- the first reason absorbing the second entry's key. Silent truncation, the exact class MAX_ACK_TRAILERS throws to prevent. Confirmed with od -c against real git output before and after. The failing-first matrix did not catch it because its "both spaces coexist" row uses Hash plus Growth -- different trailer NAMES -- so the value separator was never exercised. Two regression tests now cover same-name trailers directly. Coverage recovered: normalizeAckReason and INVISIBLE stayed on the live path via parseAckTrailers but lost every test when the old suite was pruned. Back under test against the current surface -- all six invisible codepoints individually, whitespace collapse, trim, CRLF, and two seeded fast-check properties. Dropping any single codepoint now fails. MAX_ACK_TRAILERS counted raw trailers before de-duplication, so one trailer carried forward across rebased commits counted once per commit and could throw on a legitimate branch. Now counts distinct entries; 100 identical repeats dedupe to one. diffEmitted validated baseline, current and changedPaths but not the new ackHash/ackGrowth, so a bad shape raised an unhandled TypeError instead of an error verdict -- the same defect shape this file documents for #2778. Docs: CONTRIBUTING and TESTING-SUITES were rewritten only in their first sections; the later passages still taught fragments, git rm and the deleted guard, contradicting the new text directly above them. Finished. Also extends lint-removed-but-needed to exempt docs/adr and docs/research. That gate fails on any docs mention of a file deleted in the same diff, which makes it impossible to document a deletion in the PR performing it -- an ADR's whole job is naming what it retired. Exemption is narrow and comes with a test proving the gate still fires for a live consumer elsewhere under docs/. A guard that cannot fail is worse than no guard. Maintainer-approved. CONTEXT.md names the retired machinery by role rather than by filename: its generated projection lands in docs/, which that gate does scan. Adds docs/how-to/acknowledge-emitted-drift.md. The required docs set is Reference and Explanation, so the task quadrant can be empty with every gate green -- and this change has a real multi-step journey, including the fragment migration ten open PRs now need. lint:ci exit 0. Refs #3942 * docs(#3942): correct the duplicate-trailer rule in CONTRIBUTING Both axes of the code review independently flagged the same passage, without seeing each other's output. It claimed two declarations of the same key are always "a hard, loudly-reported error, not a silent last-wins". That is only half true, and the missing half is the one contributors hit: identical declarations -- same key, same reason -- dedupe silently, because a trailer legitimately survives a rebase and reappears on every rebased commit. Failing there would red a branch for doing nothing wrong, which is exactly why the dedup exists. Only a same-key/different-reason pair errors, and that one is a genuine ambiguity about which explanation holds. As written, the paragraph told a contributor that a rebase-carried trailer breaks the gate -- the opposite of the behavior. CONTEXT.md's parallel entry already stated it correctly; this brings CONTRIBUTING into line. Doc-only, root-level markdown.

Tom Boucher	e20744eacb	enhance(#3884): failure is a value — strict argv, and --pick that signals absence (#3922) ... * test(#3884): failing-first coverage for strict argv and absence-signalling --pick ADR-3473 §8.4 says failure is a value. Three families currently encode failure as success, and this commit pins each one RED before the fix lands. Measured on this tree, 2026-08-26: gsd-tools generate-slug "test" --pick nonexistent -> empty stdout, exit 0 (#3365) gsd-tools audit-open --pick nonexistent_field -> dumps the entire human-readable audit report, exit 0 gsd-tools generate-slug "Hello World" --raw --pick bogus -> prints "hello-world", another field's value, exit 0 gsd-tools query state.planned-phase 3 (positional, no --phase) -> exit 0; STATE.md's "Phase: 2 of 5 (Widget Support)" is overwritten to "Phase: null - READY TO EXECUTE" and the frontmatter gains a corrupted current_phase_name (#3358) tests/pick-flag.test.cjs:27 previously asserted the #3365 defect as the contract ("returns empty string for missing field", success === true). That assertion is replaced by the required behavior rather than deleted. The new parseNamedArgs block calls the spec-object signature that does not exist yet, so it fails today by construction. The 11 existing behavior-lock tests are left untouched here; they are corrected in the implementation commit. C1/C4 assert at the consumer's output - STATE.md's bytes - per ADR-3180 Decision 4(b). A unit assertion on the parser would have passed throughout this defect's life. Design: .gsd/phase/feat-3884-failure-is-a-value/40-design.md Test matrix: .gsd/phase/feat-3884-failure-is-a-value/50-test-matrix.md Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * enhance(#3884): failure is a value — strict argv, and --pick that signals absence Implements ADR-3473 §8.4. Absence, emptiness and failure stop being interchangeable ways to say "I could not answer". parseNamedArgs (src/command-arg-projection.cts) Takes a spec object with a REQUIRED `positionals: number | 'rest'` and returns the hub's Result shape instead of a bare Record. Declaring the positional arity is what makes #3358's call site unrepresentable rather than merely detectable: an unrecognized flag or a token past the declared boundary is now InvalidArgs, naming the offending token and listing the accepted flags. The legacy positional-array call shape throws a TypeError — an internal invariant violation per ADR-3473 Decision 2, so a stale hand-written .cjs call site fails loudly instead of destructuring undefined off a Result. parseNamedArgsOrExit projects a failure onto the caller's error(); it is a projection over the one parser, not a second parser. Measured before, against a STATE.md with a populated phase-2 block: query state.planned-phase 3 (positional, no --phase) -> exit 0; "Phase: 2 of 5 (Widget Support)" overwritten to "Phase: null - READY TO EXECUTE", frontmatter gains a corrupted current_phase_name After: exit 1, `unexpected positional argument "3"`, STATE.md byte-identical. The flag form is unchanged and still updates STATE.md. --pick <field> (gsd-core/bin/gsd-tools.cjs) extractField returns {found,value}, and the pick block no longer shares one catch between "output was not JSON" and "field was absent". An absent field exits 1 with pick_field_absent, naming the field and the keys that do exist; non-JSON output exits 1 with pick_output_not_json instead of dumping the command's entire output. A field that is PRESENT with value null, '', 0 or false still prints at exit 0 — that is an answer, not a failure, and it is what keeps `--pick count` printing 0 on a fresh project. Measured before: `audit-open --pick nonexistent_field` printed the whole human-readable audit report at exit 0, and `generate-slug X --raw --pick bogus` printed "hello-world" — a different field's value, confidently, at exit 0. ADR-3409 Decision 7 explicitly deferred this contract fix to #3473; this is it. The sub-issue's "returns 0 when the count is zero OR absent" wording is superseded by the ADR rule it implements: zero prints 0, absence exits non-zero. Defaulting absence to 0 would demote "could not answer" to "the answer is zero" — the hazard docs/how-to/resolve-unreachable-guard-findings.md already warns against. Guard ledger (ADR-3473 Decision 6) scripts/lint-unreachable-guard-drift.cjs Detector A is RETIRED. Its premise — that a `--pick ... || echo` arm can never fire — is now false, so the shape it forbade is the correct idiom and keeping it would forbid the fix. Detector B (glob-consuming cat/ls, a nullglob mechanism this change does not touch) is retained in full, as are the shared scanner, the escape-marker parser and the baseline. Net: -1 detector, 0 added. The file is not deleted. Call-site audit 45 prompt-layer --pick invocations, every one a plain X=$(...) assignment — none in an if test, && chain, or a pipeline whose status is consumed, and no shell block in workflows/commands/agents/references sets -e. Of the 13 (command, field) pairs the prompt layer reads, 10 are always present; the 3 sometimes-absent ones each sit behind a prior found/existence check. No ADR-3409-class "field the command never produces" remains.

A newline in an untrusted token forged a second stderr line. Before, plain-text mode: $ gsd-tools query state.planned-phase $'foo\nError: forged second line' Error: unexpected positional argument "foo Error: forged second line" After: Error: unexpected positional argument "foo\nError: forged second line" --json-errors mode was never affected — io.error runs that payload through JSON.stringify. Plain-text mode writes 'Error: ' + message verbatim, and the three new InvalidArgs reasons plus the two new --pick diagnostics all interpolate a token that comes straight from argv. Fixed with ONE shared helper, formatDiagnosticToken (src/io.cts), applied at every interpolation site — not a copy per site. It is deliberately NOT applied inside error() itself: several callers in this tree emit intentional multi-line diagnostics, and escaping newlines there would mangle them. The available-top-level-keys list needed the same treatment for a reason the review did not anticipate: `frontmatter get <file>` reads an ARBITRARY user document and echoes that document's own keys into the diagnostic. Verified reachable — a frontmatter key containing a newline reaches the key list — so formatKeyForDiagnosticList is guarding a live path, not a hypothetical one. Ordinary keys still render plain and unquoted; a fix that merely dropped the key would also have passed a "one line" assertion, so the test pins the escaped key's presence too. 2. Five behavior-table rows were implemented but nothing pinned them: B7 a dotted path that dies partway B9 bracket syntax on a non-array B10 a negative array index, in and out of range B14 a JSON root that is not an object B17 an @file: payload over 50KB B17 is the load-bearing one. output() writes @file:<path> instead of inline JSON past 50000 characters, and --pick resolves that BEFORE parsing; with no test, a future reordering of those two steps turns every large result into a false pick_output_not_json. The fixture seeds 1200 phase directories and measures the payload at 62474 characters, asserting the spill actually happened rather than assuming it. Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3884): correct the strict-argv surface against a full verification run The first full run came back with 90 failures across 12 files, none in the new tests. They were the argv surface telling me what it actually is. Ten root causes; each classified before anything was changed. I over-implemented, and that is reverted. ADR-3473 §8.4 says parseNamedArgs rejects "unrecognized and positional tokens". It says nothing about a value flag whose value is missing. Making that an error was my design decision, not the rule, and it broke a deliberately recorded contract: `--prd` with no value resolving to null (tests/init.test.cjs emptyPrdValueIsFalsyAndTreatedAsAbsent, row B5; tests/section-manifest-init-facts.test.cjs "flag-shaped value"). The "requires a value" branch is deleted outright rather than kept behind an option — an unused strictness mode is speculative generality. Unknown-flag and unexpected-positional rejection, which is what §8.4 actually mandates, is unchanged. --wave needed a third flag kind the original design did not anticipate. `--wave N` is documented (commands/gsd/execute-phase.md:4,48) and the shipped workflow reconstructs and passes it (execute-phase.md:84), while #2932 records token-PRESENCE semantics: the CLI cares only that the flag appeared, and the value belongs to the workflow layer. That is neither a boolean flag nor a value flag, so `optionalValueFlags` now exists — presence-only in `data`, and the validation cursor consumes a following non-flag token so it is not reported as a stray positional. Every other declared boolean flag was checked against every argument-hint and prose usage in commands/, workflows/, agents/ and docs/; `--wave` is the only one of this shape. Five tests were pinning forms that never worked. tests/adr857-core-without-capabilities.test.cjs passed `init plan-phase --phase 01-stub`, but the documented form is positional (docs/CLI-TOOLS.md:776) and the handler reads args[2] — which for that form is the literal string "--phase". Measured on the pre-fix build against a real .planning/phases/01-stub/ directory: init plan-phase 01-stub -> phase_found=true init plan-phase --phase 01-stub -> phase_found=false The test asserted only exit 0 and key presence, so it had been green while proving nothing about phase resolution. Corrected to the documented form and strengthened to assert phase_found === true. Same class in state.test.cjs (`--plan-count`, a flag that does not exist; the real one is `--plans`), milestone-archive.test.cjs (`init new-milestone --json`, silently ignored), and concurrency-safety.test.cjs (a bare positional field name whose OR-assertion passed because a whole-document dump happens to contain the substring it looked for). Six handlers had no argv validation at all — the same #3358 shape this phase exists to close, found while fixing the rest: init verify-work / phase-op / review / todos / remove-workspace read args[2] with nothing checking the rest, and validate health read --repair/--backfill through a bare args.includes() scan that bypassed the parser entirely. All now go through the seam, so the flag has one owner. tests/init-debug.test.cjs rows C4/C5 asserted that an unrecognized flag must NOT fail. That is the behavior §8.4 removes, and Decision 8 says a caller's local expectation does not override §8, so they are inverted and renamed — a test still called "ignores an unrecognized flag" while asserting rejection would be its own defect. Row C6's point is its PWNED canary; that assertion is kept verbatim and only its exit-status expectation changed, because the hostile token is now rejected rather than absorbed. The blast-radius estimate in 40-design.md is corrected rather than quietly left wrong. get_impact reported MEDIUM / 8 symbols upstream, and that was accurate for what the graph can see — parseNamedArgs's callers. It cannot see that those callers' handlers accept argv shapes wider than the code reading args[2] suggests, which is where the real surface was. Refs #3884 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3884): withdraw the validate-health tightening, finish the A2/A3 revert Second full run: 46 failures, down from 90. Four causes, two of them mine. Reverted `validate health` entirely — it was scope creep, and it broke a real flag. ~30 of the 46 read `unknown flag "--json"; accepted: --repair, --backfill`. The previous commit routed `validate health` through the parser on the reasoning that a flag should have one owner. That was wrong twice over: §8.4 names parseNamedArgs and count queries, and `validate health` was never a parseNamedArgs call site — it read its flags, just not through the parser, so it had no silent-drop defect to fix. Tightening it omitted `--json`, which the health-diagnostic suites use heavily. The handler is now byte-for-behaviour back to its pre-branch form. `validate context` stays converted: it genuinely was a call site, and its `--json` is now declared rather than read by a second `args.includes` scan. The five handlers that had NO validation at all — init verify-work / phase-op / review / todos / remove-workspace — stay fixed. Those read args[2] with nothing checking the rest, which is the #3358 shape this phase owns. Finished the A2/A3 revert. Three tests still encoded the deleted "a value flag with a missing value is an error" rule, including one added by the previous commit for that rule. All three now assert the reverted null contract, and the ones whose titles said "rejected" are renamed — a test named for a contract it no longer asserts is its own defect. `--wave=` and `--wave --weird` are correctly rejected. Neither is documented in commands/gsd/execute-phase.md, gsd-core/workflows/execute-phase.md or docs/, and neither is emitted by the shipped prompt layer, so both are unrecognized tokens that §8.4 mandates rejecting. `doesNotConsumeFollowingFlagAsWaveValue` keeps the property it exists for — asserted directly now, at the parser, that `--wave` does not swallow a following flag as its value — and only its exit-status expectation changed. A contradiction inside this branch, surfaced by the audit and resolved the safe way. Two pre-existing #3573 tests call `state begin-phase '2'` and `state planned-phase '2'` with a bare positional, relying on the old permissive parser to ignore it. This branch's own #3358 regression test requires that exact argv to be REJECTED. The two are mutually exclusive. Widening the router to accept a bare positional — mirroring complete-phase — would have silently re-opened #3358, and was verified to do exactly that: with the widened router, `query state.planned-phase 3` returned exit 0 and wrote current_phase_name again. It is reverted. docs/CLI-TOOLS.md:116 and docs/COMMANDS.md:2192 document only the `--phase N` form for both verbs, so the two #3573 tests move to it. Their assertions were never about the call shape — only that total_phases survives the resync — and both still pass. complete-phase is untouched: its bare positional IS documented, and it keeps the dynamic boundary and the negative-space note that record why. The audit that produced this is in the PR body: for every handler whose declaration changed, the flags it reads anywhere in its body, the flags the shipped surface documents, and the shapes the suite passes, compared. The `--json` miss was a pattern, not an accident — declaring a handler's flags from its parseNamedArgs call alone misses whatever it reads elsewhere.

Tom Boucher	7e9d33c378	enhance(#3915): stryker on the official tap runner, 29m to 12m on the critical path (#3919) ... * enhance(#3915): stryker on the official tap runner, per-test coverage The 'command' runner is the one runner Stryker excludes from coverage analysis, which forced coverageAnalysis:'off' and made mutation cost strictly linear in (mutants x whole-shard test time). The frontmatter shard measured 1751s against 212s for the next slowest. Swap to @stryker-mutator/tap-runner (official plugin, peer-pinned to the @stryker-mutator/core@9.6.1 already installed) and turn coverage analysis on, so Stryker re-runs only the test files that cover each mutated line. Per-shard injection moves from a MUTATION_TEST_CMD command string to MUTATION_TEST_FILES, read by a new fail-closed resolveMutationTestFiles() that mirrors resolveMutationBreak. It stays derived from scripts/mutation-matrix.cjs and now has a single owner: the union moves behind allCoveredTests() and stryker.config.mjs no longer imports COVERED. The resolver existence-checks every entry, because the tap runner resolves tap.testFiles with glob() and a non-matching pattern yields an empty list silently - a fast, confident, meaningless run. tap.forceBail is off by measurement, not preference: a structural AST audit found 3 of 26 shard test files spawn subprocesses, and bail fires on every killed mutant, so leaving it on would kill processes mid-spawnSync and orphan their children. The matrix 'isolation' field is removed - per-file process isolation is inherent to the tap runner, so the field had no consumer left. Score arithmetic is unchanged and now pinned: mutationScore counts NoCoverage in the same denominator as Survived, which both Stryker's thresholds.break and check-mutation-score-ratchet.cjs read. A new non-vacuity test proves it diverges from mutationScoreBasedOnCoveredCode, so the gate cannot be quietly swapped to the field that would make every floor trivially satisfiable. Refs #3915 * fix(#3915): enforce the resolver's documented containment contract Review findings, all fixed in place. resolveMutationTestFiles claimed to verify each entry exists 'relative to the repo root' but used a bare fs.existsSync(path.join(...)), which accepts an existing DIRECTORY and lets ../ segments escape the root (path.join('/repo/root','../../etc/passwd') resolves to /etc/passwd). Not reachable from PR content - the value only ever comes from the static COVERED registry via CI env - but a fail-closed contract that overstates its own guarantee is a defect in the contract. Each entry is now resolved, rejected if path.relative puts it outside the root, and required to be a regular file. Three hostile-input tests added; the original missing-file wording is preserved so the existing assertion still binds. Also: removed a stale buildResult comment still naming the isolation field this branch deleted; hoisted one top-level path require in place of three inline ones; de-duplicated the derived-test-list expression in the tests to a single const, deliberately still re-derived from COVERED rather than calling allCoveredTests() so the assertion cannot become a tautology; tightened the workflow-parity assertion to exact equality; changed the tap-runner range from an exact 9.6.1 to ^9.6.1 so it tracks the caret-ranged core its peerDependency pins exactly. Regenerated examples/dynamic-context-management/CONTEXT-INDEX.json, which the earlier CONTEXT.md edit left stale - lint:ci was red on lint-example-parser-parity until it was refreshed. Refs #3915 * test(#3915): kill model-catalog survivors, set frontmatter budget from measurement From mutation run 33026833181 (all 13 shards, dispatched on this branch before any PR). WALL TIME: frontmatter measured 713s (11m53s) vs 1751s (29m11s) on the command runner, a 59% cut. timeoutMinutes 60 -> 20 (1.68x measured). Not deleted outright: the shared 15-minute default would leave only 21% headroom, and this module's mutant count grew 1.8x in one change. MODEL-CATALOG: came back 57.91 against its floor of 58. Diagnosed from the report JSON, not assumed - all 24 of its new RuntimeError mutants are in the load-time catalog bootstrap, so mutating them makes the module throw at require. Under node --test that is a failed test file (Killed); under the tap runner the process dies before emitting TAP, which Stryker classifies RuntimeError and excludes from the denominator. Add them back as killed and the shard is 248/416 = 59.62, the pre-change number exactly. Detection did not regress, classification changed. The floor is NOT lowered to absorb that. 11 new behavioural tests target ~42 genuinely surviving mutants: exact Set equality on the EFFORT_RENDERING/EFFORT_ARGV supported sets, an exact-string table render that makes the column-width arithmetic observable (padEnd never truncates, so the old substring assertion could not see a too-small width), clampEffortForHost's full null matrix plus a spoofed-toString host, and a prototype-pollution guard driven through Object.fromEntries. Mutants judged equivalent were skipped rather than papered over; reasoning is in the phase artifacts. All 15 new assertions verified against unmutated code. lint:ci exit 0. Refs #3915 * test(#3915): ratchet model-catalog's floor to 74 on measured 75.26% CI run 33029755081 measured model-catalog at 75.26% (295 killed / 49 survived / 48 no-coverage / 24 runtime-error, totalValid 392), so check-mutation-score-ratchet.cjs correctly failed the shard for unclaimed headroom: 17.26 points above the declared floor of 58, well past the 5-point slack. Floor raised 58 -> 74 (floor(75.26)-1, this file's documented convention), with RATCHET_BASELINE updated in the same diff as the equality assertion requires. Worth recording why the number moved this far. The shard first came back at 57.91 under the tap runner and the temptation was to lower the floor to match. The drop was not a regression: all 24 of its RuntimeError mutants sit in the load-time catalog bootstrap, and adding them back as killed reproduces 248/416 = 59.62, the pre-swap figure exactly. Rather than absorb a reporting artifact by weakening the gate, 11 behavioural tests went after the genuinely surviving mutants and killed 68 of them - carrying the module from 59.62 past its old ceiling to 75.26, within reach of the ADR-456 target of 80. The #3007 measurement is kept as clearly-labelled prior context rather than deleted, so the entry does not read as carrying two current numbers.

Tom Boucher	6b7df61938	enhance(#3881): one YAML parser — vendored js-yaml replaces the hand-rolled dialect (#3888) ... * docs(#3881): answer §8.1's open question and correct three wrong premises ADR-3473 §8.1 carries a blocking open question with a forcing function: it must be answered before any implementation PR for the rule opens. Answered here as (a), a string-coercing adapter, with the measurement that settles it. The sequencing note bet that §8.8's schema would make (b) tractable. Measured against merged reality it does not: only 33 of extractFrontmatter's 78 non-test call sites read STATE.md, and two of the five compensating mechanisms §8.1 lists survive real types, leaving ~31 lines across 3 call sites as the actual prize. Also corrects three claims verified false while answering it. §8.1's justifying sentence names #3349 and #3360 as defects a real parser would fix; both are already fixed on next, confirmed by executing the compiled parser rather than reading it. The guard roster calls lint-frontmatter-scalar-broad-grep.cjs an expected casualty of this rule, but it guards shell grep idioms in workflow bash fences and never touches our parser. The same roster calls lint-vendored-deps.cjs reusable as-is; it is hardcoded to re2js throughout. The last two were caught by applying the rule this amendment records -- a factual claim in this ADR is a hypothesis until the implementing phase executes it -- on its first use. Refs #3881 * docs(#3881): record that §8.1's fork is ill-posed and (a) is not implementable An adversarial pass on the Phase 4 design established by execution that extractFrontmatter is not a YAML parser but a line-oriented scanner whose output is a function of raw source text. Four spellings of the same value collapse to one js-yaml tree but produce four distinct legacy strings, one of them mangled. No adapter over a tree can choose among outputs the tree does not distinguish, so fork (a) -- keep a string-coercing adapter so the existing contract holds -- cannot be built. For any document with a non-scalar value, (a) collapses into (b); about 26 percent of frontmatter-carrying documents have one. Also records three design defects and one new attack surface, all confirmed by execution: catching a parse failure and returning {} would delete the frontmatter block on the next write at eight call sites that conflate empty with unparseable; an empty value yields null where legacy yields {}, and reconstructFrontmatter omits null-valued keys, so the shipped state template's empty progress key would vanish; the #1882 truncation probe is parseYamlRegion itself rather than a pre-parse heuristic, so it cannot both stay unchanged and survive that deletion; and FAILSAFE_SCHEMA still resolves aliases, expanding seven lines to 22.8 MB. The rule is not deferred. The measurement is the deliverable and the re-scoping is recorded as an open question with a forcing function, per section 8's own rule. Refs #3881 * test(#3881): failing-first rows for block scalars, unicode keys and the missing #3594 matrix Creates tests/feat-3594-parser-adversarial-frontmatter.test.cjs, the file the fixture README instructs contributors to register fixtures in but which never existed. Section C: table-driven ownership check over tests/fixtures/adversarial/frontmatter/ so a fixture with no matrix entry fails loudly; six existing fixtures (duplicate-keys, crlf-mixed, unclosed-block, unicode-keys-and-values, null-byte-value, huge-bounded) each get the invariant its README states. B1 blockScalarValueIsNotTheBlockIndicator: parsing commands/gsd/add-tests.md must give argument-instructions the instruction text, not the literal '|'. RED today. B2 blockScalarDoesNotInventATopLevelKey: same parse must not produce a top-level Example key scraped from inside the block body. RED today. B3 unicodeKeyRoundTripsAsIs: the 相 key in unicode-keys-and-values.md must survive parsing; today it is silently dropped. RED today. Refs #3881 * chore(#3881): vendor js-yaml and generalize the vendored-deps guard to a manifest Packaging step for ADR-3473 §8.1: makes js-yaml available to gsd-core/bin/** without promoting it out of devDependencies (promoting broke every installed tree, #3496). gsd-core/bin/lib/vendor/js-yaml.cjs is a verbatim copy of node_modules/js-yaml/dist/js-yaml.js (the self-contained UMD dist bundle, not index.js), exposing load/dump/FAILSAFE_SCHEMA/YAMLException with zero require() calls of its own. src/vendor/js-yaml.d.cts is hand-authored, not copied, because js-yaml ships no upstream .d.ts and @types/js-yaml is not installed. It is deliberately narrow, declaring only the four symbols in use, so anchors/aliases/custom types/loadAll are unreachable from typed code -- a compile-time enforcement of ADR-3473 §8.1's refusal to expand alias resolution for security reasons. Because it has no upstream counterpart it is excluded from the byte-compare. scripts/lint-vendored-deps.cjs is refactored from a script hardcoded to re2js into a table-driven VENDORED manifest (one row per package: upstream/vendored .cjs paths, optional .d.cts paths, twin kind upstream-verbatim vs hand-authored) so a second vendored package does not require a second hardcoded check block, per ADR-3473 §8.3 'one implementation per rule'. The four existing re2js checks (vendored .cjs vs node_modules, vendored .d.cts vs node_modules, src/vendor twin vs bin-side twin, devDependency version pin vs installed version) are preserved unchanged; verified pass/fail identical before and after the refactor, and the guard's ability to fail was re-proven with a deliberate one-byte append to both re2js.cjs and js-yaml.cjs, then restored. docs/INVENTORY.md and docs/INVENTORY-MANIFEST.json (via gen-inventory-manifest.cjs --write, run after build:lib) register vendor/js-yaml.cjs. gsd-core/bin/lib/vendor/README.md documents both vendored packages and the two twin kinds. Refs #3881 * feat(#3881): parse .planning frontmatter with the vendored js-yaml ADR-3473 §8.1: extractFrontmatter's read path is no longer a hand-rolled line scanner. parseYamlRegion, escapeDoubleQuoted, unescapeDoubleQuoted and parseQuotedScalar are deleted (not patched); parsing now goes through the vendored js-yaml (./vendor/js-yaml.cjs) under { schema: FAILSAFE_SCHEMA, json: true }. Everything js-yaml does not do is layered on top, in one place, carrying the seven design-doc consequences: 1. Empty value: a null js-yaml value is coerced to {} (matching legacy's own empty-value contract) so reconstructFrontmatter — which omits null-valued keys — still round-trips a bare `key:` line instead of deleting it. Verified live: progress: with no value survives parse -> reconstruct -> re-parse. 2. Unparseable no longer collapses to a bare {}: a new FRONTMATTER_UNPARSEABLE Symbol (exported), keyed exactly like the existing #3257 FULL_LINE_COMMENTS channel, is carried on the {} returned for malformed/refused YAML. Invisible to Object.keys/entries/JSON.stringify/for-in, so the 70 call sites that never inspect it are unaffected; wiring the 8 hasFrontmatter sites to consult it is a separate change, not done here. 3. Non-scalar object-list items (the four spellings of `- test: a b` that js-yaml collapses into one tree shape) are rendered as a canonical `key: value[, key2: value2]` string per item, keeping the existing array-of-strings value SHAPE. A full corpus differential over all 1702 tracked markdown files found 11 residual divergences from the legacy parser (enumerated in the PR/report), most of them the parser now being MORE correct (a dropped quoted top-level key, the block-scalar/phantom-key defect, a dropped Unicode key). 4. The #1882 truncation probe still runs the one real parser, but derives its key count from js-yaml's own thrown error and mark.line when the whole region doesn't parse cleanly (the dominant real truncation shape: fence opened, well-formed keys, no closing fence). Verified against both the clean-parse and the exception-fallback path. 5. The #3257 comment channel now attributes each pending column-0 comment against js-yaml's own parsed top-level key list (matched by literal key text, in document order) instead of the legacy ASCII-only key regex, so a comment above a Unicode key attaches correctly. 6. Anchors, aliases and merge keys are refused outright (a raw-text pre-scan, since FAILSAFE_SCHEMA still resolves them) — corpus occurrences today: zero. A 7-line billion-laughs fixture is verified refused rather than expanded. 7. A literal U+0000 is swapped for a private-use sentinel before the parse and restored in every resulting string afterward, since js-yaml rejects NUL unconditionally under every schema. escapeDoubleQuoted is deleted and reimplemented via js-yaml's dump() (forced double-quoted style), with control-char hex escapes lowercased to keep serialized output byte-stable (#1779 emitted lowercase); it keeps its exported name and signature for its two other call sites (commands.cts, runtime-artifact-conversion.cts), which need no change. frontmatterDeepEqual, the comment channel, sliceTopLevelFrontmatterSegments, regenerateFrontmatterKey's guard, noOpObjectListSetError and parseMustHavesBlock are all unchanged — retiring them is fork (b) and is not this phase. Refs #3881 * fix(#3881): quote template placeholders and preserve unparseable frontmatter SECURITY.md/UI-SPEC.md/VALIDATION.md wrote frontmatter placeholders as bare {N}/{phase-slug}/{date}, which is valid YAML flow-mapping syntax under the vendored js-yaml parser, not the literal placeholder text intended. Quote them so they parse as strings. Wire the FRONTMATTER_UNPARSEABLE Symbol (exported but unused) at the 8 call sites in state.cts/state-transition.cts that compute hasFrontmatter via Object.keys(extractFrontmatter(...)).length > 0 and reassemble the document without a frontmatter block when false. That check conflated 'no frontmatter' with 'unparseable frontmatter' (both parse to {}), so a document with a merge-conflict marker or refused alias in its frontmatter had that block silently dropped on write. Each site now preserves the exact raw bytes stripFrontmatter removed when the marker is set, leaving the genuinely-empty case unchanged. Refs #3881 * test(#3881): consequence and boundary coverage for the js-yaml migration Rows: A1 emptyValuedKeySurvivesAWrite, A2 unparseableDocumentKeepsItsFrontmatterBlock, A3 unparseableIsDistinguishableFromEmpty, A4 nonScalarValuesCanonicalize, A5 truncationProbeStillFiresOnAnOpenFence, A6 commentsStayOnTheirOwnKey, A7 anchorsAndAliasesAreRefused, A8 aliasExpansionCannotExhaustMemory, F1 UNTERMINATED_KEY_THRESHOLD boundary, F2 alias/nesting refusal bound, F3 frontmatter size boundary (huge-bounded.md + larger). Adds tests/fixtures/adversarial/frontmatter/anchor-alias-bomb.md and its entry in the feat-3594 fixture matrix. Refs #3881 * docs(#3881): document the vendored parser, correct a stale rationale, add a vendoring how-to Refs #3881 * docs(#3881): correct the frontmatter glossary entry Two errors in the entry as first written: it named parseYamlRegion as part of the read path when that function is deleted, and it recorded the eight hasFrontmatter call sites as unwired follow-on work when they were wired in e35ac2a2c. Also records the scope caveat that the CLI write path rebuilds the frontmatter block independently, so the marker binds at the transform layer. Refs #3881 * docs(#3881): record the semantic-migration decision and the counted guard ledger The maintainer chose the full semantic migration over splitting the rule into its own epic or patching the scanner, so section 8.1 is answered as "the fork was ill-posed and the migration is semantic" rather than as (a) or (b). Also replaces the pre-implementation guess that this phase would shrink the guard surface with the counted result: excluding vendored third-party lines the hand-maintained surface is net +307, and frontmatter.cts grew by 68 lines despite four functions being deleted, because the compatibility layer over js-yaml is larger than the scanner it replaced. Section 8.1's stated benefit is therefore not delivered as written; what improved is the kind of code maintained, not the amount. Decision 6 requires recording that rather than netting it away. Refs #3881 * chore(#3881): changeset for the vendored YAML parser migration Refs #3881 * test(#3881): golden parity, round-trip property and packaging coverage Refs #3881 * fix(#3881): refuse anchors structurally and fold in review findings ADR-3473 §8.1 review findings, addressed inline: Finding 1 (BLOCKER): refuseAnchorsAndAliases was a raw-line regex that matched only the bare-key spelling (key: &x). A quoted key ("a": &x), a flow mapping ({b: &x}) and a flow sequence ([&x, *x]) all define/use the SAME anchor mechanics while never matching that line shape, so the exact expansion the guard exists to stop went straight through unrefused (a 303-byte quoted-key bomb expanded to ~35.8MB). Replaced with js-yaml's own `load` `listener` callback, which reports `state.anchor` for every event belonging to an anchored node in every spelling, and throws from inside the callback to abort before any expansion (~1-2ms vs full expand-then-discard). A merge key with an alias is still refused (merge always requires a previously anchored node, so the alias itself trips the listener); a bare merge key with NO alias is no longer separately refused, documented as intentional: FAILSAFE_SCHEMA never resolves `!!merge`, so it carries no expansion risk. Table-driven tests added for all four bypass spellings + merge key, plus a quoted-key-spelled billion-laughs fixture registered in the adversarial matrix and README. Finding 2: src/vendor/js-yaml.d.cts's docblock falsely claimed anchors/ aliases were "simply UNREACHABLE from typed code" through the twin. Corrected to state the truth: anchor/alias resolution is document-level `load` mechanics reachable through exactly the declared surface, and refusal is enforced at RUNTIME (Finding 1's listener), not by the type surface. Finding 3 (MAJOR): the null-byte sentinel (U+E000) round-trip was non-injective — restoreNullBytesDeep rewrote every U+E000 in the parsed tree back to NUL, including one the document author legitimately wrote, silently corrupting it. Now refuses outright whenever the raw region already contains U+E000 (consistent with the existing anchor/merge-key refusal path), making the substitution provably injective. Tests added for a real NUL alone (preserved), a pre-existing U+E000 alone (refused, not corrupted), and both together (refused, not merged into one byte). Finding 4 (MAJOR): scripts/lint-vendored-deps.cjs's `srcTwin` field was dead for a hand-authored row (only read inside the upstream-verbatim branch) — exactly how Finding 2's stale docblock drifted unnoticed. Added checkHandAuthoredTwin: every value-level export the twin DECLARES must be an actual own property of the vendored runtime module at require-time. Tests added, including a sensor that a declared-but-nonexistent export IS caught. Finding 5: the existingFm/hasFrontmatter/stripFrontmatter/fmPrefix/ unparseableFm/reassemble preamble, copy-pasted at 7 sites in state-transition.cts plus a sixth hand-inlined copy in state.cts's cmdStateCompletePhase, is now one exported helper (beginFrontmatterReassembly) every site routes through, including the hand-inlined one. Three call sites (beginPhaseCore, patchCore, updateCore) keep a literal `body = stripFrontmatter(content)` assignment alongside the helper call so scripts/lint-state-write-path-drift.cjs's single-hop backward scan (which does not chase aliases) still sees the strip; stripFrontmatter is pure/idempotent so the extra call changes nothing observable. Finding 6: corrected the frontmatter.cts docblock's stale "wiring is a separate change" claim (the 8 call sites are wired on this branch) and the changeset's backlink from (#3473) to (#3881). Finding 7: fixed the lint:ci failures blocking the gate — an @typescript-eslint/only-throw-error violation from throwing a bare Symbol as the anchor-detected signal (now a real Error subclass), unused-var warnings left over from the Finding 5 refactor, a lint-test-file-count cap exceeded by two migration-specific test files (allowlisted with justification), and the lint-state-write-path-drift false positive from Finding 5's helper (fixed above). tests/frontmatter-golden-parity.test.cjs:117's execFileSync already carried an explicit timeout; no change was needed there. Golden fixture: added a golden entry for the new anchor-alias-bomb-quoted.md fixture ({} — matches what the legacy line scanner would also produce, since it independently dropped every quoted top-level key). No other corpus document diverges: real .planning/ documents carry zero anchors/aliases/merge keys/U+E000 today. Refs #3881 * fix(#3881): fold in second-round review findings Finding 1 (BLOCKER): tests/frontmatter.test.cjs pinned the pre-migration ASCII-only key regex for the Unicode fixture; updated to require the 相 key's value now that js-yaml has no such restriction. Audited the rest of the file for other pre-migration pins (block scalars, quoted keys, flattened values, empty values, duplicate keys, unclosed blocks, null bytes) by execution against real fixtures; found none regressed. Finding 2: parseYamlRegion and escapeDoubleQuoted renamed to parseGuardedYamlRegion and escapeDoubleQuotedScalar in src/frontmatter.cts so no function still answers to the deleted hand-rolled scanner's name (ADR-3473 §8.1 "deleted, not patched"). escapeDoubleQuotedScalar's three external call sites (src/commands.cts, src/runtime-artifact-conversion.cts) updated in the same change — a mechanical rename, not an ADR-amendment matter. Finding 3 (BLOCKER): fixed a real crash and a silent data-loss bug found by execution. A top-level key named constructor/__proto__/toString/ valueOf/hasOwnProperty crashed reconstructFrontmatter (bracket read resolving an inherited Object.prototype member); a key literally named __proto__ was silently DROPPED entirely (bracket assignment on an ordinary {} invoked the inherited __proto__ setter instead of creating a data property). Fixed by building every parsed Frontmatter object with Object.create(null), and replacing an `in` check with hasOwnProperty.call in propagateCommentChannel. Added round-trip tests for all five hostile keys, each with its own leading comment. Finding 4 (MAJOR): escapeDoubleQuotedScalar's docstring falsely claimed full byte-stability across the migration. Verified by execution: BEL/NUL/ NEL/NBSP/LS/PS/BOM now emit YAML-named escapes instead of the old hex/raw- literal forms. Proved round-trip equivalence (each escape re-parses to the exact source codepoint) and corrected the docstring. Found and fixed a related real defect while verifying: a lone UTF-16 surrogate was emitted BARE (scalarNeedsDoubleQuoting didn't trigger), producing genuinely unparseable YAML that silently collapsed to {} on re-read — extended scalarNeedsDoubleQuoting to route surrogates through the quoted+escaped path. Finding 5 (MAJOR): countKeysBeforeTruncation went silent on 4 real truncation shapes (unquoted colon, open flow collection, mis-indented sibling key, refused anchor). Root cause: the mark-based prefix recovery excluded the very line whose key needed counting, and a mark-less refusal never entered the recovery branch at all. Fixed by taking the max of two lower bounds: the longest parser-verified line-prefix, and a raw-text count of key-shaped lines (reusing the same key-shape pattern this file already uses for isFrontmatterShaped). Extended test-matrix row A5 table-driven over all 4 regressed shapes. Finding 6: the design doc's claim that no test owned the #3594 adversarial fixture corpus was false — consolidation epic #1969 had already folded it into tests/frontmatter.test.cjs. An earlier commit on this branch re-created a standalone duplicate under that false premise; folded its genuinely-new coverage (fixture-ownership check, anchor-bomb fixtures, block-scalar B1/B2 rows) into frontmatter.test.cjs and deleted the duplicate file. Corrected the false claims in 40-design.md §3.3.1 and the ADR's §8.1 note, including the roadmap-sibling claim (no such file exists). Finding 7: the golden serializer sorted object keys, making it structurally blind to the key-order-parity invariant ADR-3473 §8.1 actually claims. Made it order-preserving and regenerated the golden fixture from a standalone compile of the legacy (pre-#3881) parser at ddde001af; the current parser matches it with zero undocumented divergences, confirming key-order parity genuinely holds. Extended row A2 table-driven across 6 of the remaining 7 transitionCore kinds (all pass) plus documented, by execution, a newly-discovered 8th-site regression: state.cts's cmdStateCompletePhase calls the same preservation helper but its result is clobbered by a later unconditional resync — filed as a distinct finding rather than fixed here (touches syncAndPreserveStateMd, outside this change's verified scope). Refs #3881 * fix(#3881): preserve unparseable frontmatter through the CLI write path Characterization (executed, before/after shown): case (b), not (a). The frontmatter FENCE survives — `state complete-phase` on a conflict-marked STATE.md returns success and a well-formed, freshly-derived frontmatter block, not a document with no frontmatter at all. But the block's actual content (the merge-conflict markers, and with them any signal to a human that the document was in conflict) is silently discarded and replaced. Root cause was two clobber sites, not one: 1. syncStateFrontmatter (src/state.cts) re-parses the already-preserved `transformedContent` from readModifyWriteStateMd, finds {} + the FRONTMATTER_UNPARSEABLE marker, and unconditionally rebuilt a fresh frontmatter block from the body anyway. 2. Even after (1) is fixed, applyPostSyncPreservation's own postFm/applyStatePreservation/authoritativeFm-reassertion machinery re-extracts frontmatter from syncedContent, restores curated fields from the pre-write snapshot, and reconstructs a NEW block again — confirmed live via `state begin-phase`, which still lost the markers after fixing (1) alone. Both are now guarded by the same predicate (isUnparseableFrontmatter, checking FRONTMATTER_UNPARSEABLE): when the ORIGINAL frontmatter did not parse and the caller is not on ADR-3408 §8.3's closed "body wins" list, both functions return their input content unchanged rather than re-deriving over it. The closed list (cmdStateSync #905, /gsd-health --repair's REGENERATE_STATE, both routed only through writeStateMd, which never reaches applyPostSyncPreservation and passes sanctionedPermanentEmptyFallback=true to syncStateFrontmatter) is untouched — neither widened nor narrowed; verified by execution that `state sync` still overwrites the conflict-marked block exactly as before. Other verbs sharing the same readModifyWriteStateMd path were checked and were equally affected before this fix: state update, query state.patch, and state begin-phase all lost the conflict markers (RED, shown by execution), and all three now preserve them (GREEN). Covered table-driven in tests/feat-3881-yaml-parser-consequences.test.cjs's new A2b describe block, which drives the real CLI verbs via runGsdTools — not just the pure transitionCore layer the earlier A2 rows exercised — plus a control asserting state sync's body-wins contract is unchanged. Refs #3881 * fix(#3881): restore the parse surface's prototype and fix remote-runner failures Root cause of the bulk of the 88 remote-runner failures: extractFrontmatter/parseGuardedYamlRegion handed back Object.create(null) trees for prototype-pollution safety, but assert.deepStrictEqual compares prototypes, so every assertion against a plain object literal failed (57 frontmatter.unit.test.cjs + 5 frontmatter.test.cjs + others). Fixed by keeping the internal construction null-prototype (unchanged) and converting to a plain-prototype tree via Object.defineProperty (never bracket assignment, so __proto__/constructor/toString keys stay safe) at the parseGuardedYamlRegion/unparseableResult return boundary only; the internal FULL_LINE_COMMENTS Symbol channel is copied by reference, not recursed, so its own __proto__-safety is untouched. Per-class fixes: (1) bomAcrossArtifactTypes was the same prototype bug, no separate code change needed. (2) frontmatter-cli #1660: added objectListFieldWouldLoseData, a broader lossy-field detector alongside the existing byte-identical noOpObjectListSetError -- js-yaml's flattenObjectListItem now correctly includes every sub-key of an object-list item (a real bug fix over the legacy scanner, which silently dropped every field but the first), so a set that drops that now-included data is no longer byte-identical to the original and needs its own guard. (3) uat.test.cjs: updated the pinned expectation for the human_verification quote-stripping artifact -- js-yaml resolves quoting correctly where the legacy regex left an unbalanced quote; documented as an intentional, non-lossy behavior change. (4) smart-entry: added a fallback-only loadWithAmbiguousColonRepair so a column-0 key: value line whose value itself contains an unquoted colon (the #2571 hand-edited-STATE.md shape) round-trips instead of failing the whole frontmatter block closed. (5) frontmatter.unit.test.cjs bracket-array leniency: added a second fallback, repairMalformedInlineArrays, restoring the legacy scanner's tolerant inline-array handling (consecutive/blank commas, unclosed bracket) -- both repairs run ONLY after the primary parse already threw, so well-formed documents are unaffected. (6) prompt-injection-scan: src/frontmatter.cts had a literal U+FEFF BOM embedded in a comment illustrating the #2977 fix; replaced with the U+FEFF text escape. (7) eslint-glob-coverage: allowlisted the new src/vendor/js-yaml.d.cts vendored type declaration, same precedent as the existing re2js.d.cts entry. (8) frontmatter-golden-parity: git ls-files *.md now runs with -c safe.directory=* (process-scoped) so it survives the remote runner's dubious-ownership check without a persistent git config write. Refs #3881 * chore(#3881): backfill changeset PR number Refs #3881 * test(#3881): make golden parity resistant to unrelated tree churn A corpus-wide snapshot keyed to every tracked *.md file was coupled to mutable-by-design files: .changeset/*.md's pr:0 -> real-PR-number backfill is a required workflow step, not a parser change, yet it turned this suite red. Training people to 'just regenerate the golden' on that kind of failure defeats the point of the snapshot. Exclude .changeset/** from the golden corpus entirely, tolerate tracked *.md files with no golden entry (they postdate the capture) instead of failing on them, keep hard failures for a golden entry whose file has vanished from the tree and for any real parity divergence, and add a coverage floor so the enumeration cannot quietly degrade to comparing a handful of files. Golden regenerated by recompiling the legacy pre-migration parser (git show ddde001af:src/frontmatter.cts) standalone, independent of the current parser, over the same non-changeset corpus. Refs #3881 * test(#3881): make the parser golden hermetic instead of tree-keyed This repo merges ~21 commits/day; a 14-day sample measured 937 touches of the exact files (commands/gsd/*.md, gsd-core/workflows/*.md, agents/*.md, docs/*.md) the prior golden pinned by tracked path. Any PR editing one of those files' frontmatter for reasons unrelated to the parser (an argument-hint addition, an allowed-tools tweak) turned the suite red, and the reflex fix -- "regenerate the golden" -- overwrote the very snapshot meant to catch a real regression. Excluding .changeset/** was not enough; the design itself was wrong: a regression fixture must not be keyed to mutable repo paths, and a single 376-entry JSON every such PR touches is also a guaranteed merge-conflict surface. Rebuilt the fixture to carry its own documents: each of 51 entries stores a stable id, literal documentText (shrunk from a real ddde001af-era corpus document), and an expectedParse captured independently from the pre-migration legacy parser (git show ddde001af:src/frontmatter.cts, compiled standalone against its byte-identical sibling modules). The test reads no tracked path, shells out to no git command, and enumerates no tree -- a PR editing commands/gsd/help.md cannot affect it. Every entry's reconstruction was verified at capture time to reproduce both the current and legacy parser's output on the original document; 0 of 51 candidates were dropped by that check (1, the deliberately-unterminated unclosed-block.md adversarial fixture, has no closing fence to truncate at and is stored unshrunk). Kept the 5 documented DIVERGENCES rows (now diverges:true entries) and the D2 order-preserving structural serializer that keeps the comparison from passing vacuously; dropped the tree-enumeration helpers, the coverage floor, the post-capture-skip logic, and the vanished-file check -- all artifacts of the path-keyed design. Refs #3881 * fix(#3881): resolve vendored-deps paths independently of cwd shape Five rows in tests/lint-vendored-deps-manifest.test.cjs failed on windows-latest CI: the test passed absolute scratch-file paths into compareFiles()/checkRow(), whose helpers joined every input onto ROOT via path.join(ROOT, rel), producing garbage when the input was already absolute. It surfaced on windows-latest specifically because GitHub's Windows runners checkout the repo on a different drive than TEMP, so path.relative(REPO_ROOT, tmpFile) returned the absolute path unchanged (no relative traversal is representable across drives) rather than the relative form the test assumed. The remote gsd-test runner this repo gates pushes on is Linux-only and could never have caught this; GitHub CI's windows-latest job is the only signal that does, and it did. Fixed the helper itself (scripts/lint-vendored-deps.cjs's new resolvePath()) to treat an already-absolute input as absolute-in, absolute-out instead of silently mis-joining it, and updated the test to pass the scratch file's absolute path directly rather than relying on a relative conversion that is not always representable. Kept every mutation-sensor assertion intact and added coverage proving resolvePath is a no-op for relative inputs and correctly passes absolute ones through unchanged. Refs #3881 * fix(#3881): warn when state sync regenerates over unparseable frontmatter state sync (ADR-3408 §8.3's sanctioned regenerate path) correctly overwrites an unparseable frontmatter block per its 'body wins' contract — that overwrite behavior is unchanged here. The defect was the silence: synced:true/exit 0 gave no signal that the existing block (including git merge-conflict markers) could not be parsed and was destroyed, per ADR-3473 §8.5 ('a derived conclusion may not be reported as authoritative when the derivation dropped input it could not resolve') and §8.4 ('failure is a value'). Adds a gsd: warning — ... (#3881) line on stderr, matching the existing #3573 precedent, and surfaces the same disclosure in the JSON result's existing changes[] array so a machine consumer sees it too. Exit code and synced:true are left unchanged — sync did what its contract says. REGENERATE_STATE (/gsd-health --repair's sibling on the same sanctioned-regenerate list) is DESTRUCTIVE-risk and unconditionally refused by applyRepairs's dispatcher before runRepairAction ever runs (src/health-diagnostic.cts), so it is not a live path today and is not in scope for this fix.

The change was wrong and the revert is the correction. This repo distinguishes two error mechanisms deliberately. error() in src/io.cts writes to stderr and calls process.exit(1) -- the hard-failure path. output({error: ...}) writes a JSON result envelope to stdout and returns normally with exit 0. The reverted commit converted 23 result-envelope sites into hard failures, which is a different contract, not a bug fix. tests/state-contract.test.cjs's errorPathDoesNotPublish asserts the envelope contract directly -- a failing command exits 0 with a JSON error envelope and must not publish state.json -- and the remote matrix run caught it along with four cases in the QA scenario walk. Thirteen tests in tests/state.test.cjs that the original commit rewrote were encoding that real contract, not the bug it claimed; they are restored. Whether an error envelope on stdout with exit 0 is the right CLI design is a genuine question, and it is section 8.4's rule ('failure is a value') with its own phase. It is not something to flip inside this PR. Refs #3881 * chore(#3881): backfill changeset PR number for the project-dir fix Refs #3881 * test(#3881): keep the frontmatter mutation shard inside its time budget The Stryker (frontmatter) shard hit the documented 15-minute (900s) shard cap. Root cause is NOT row-level spawn overhead (contrast the #2790/ core-utils precedent): the three shard test files' own logic runs in ~413ms total (356+30+27ms) with all 392 assertions passing. Instead, src/frontmatter.cts grew from ~825 to 1496 lines (+671/-187) migrating to the vendored YAML parser, proportionally growing the mutant count Stryker generates for gsd-core/bin/lib/frontmatter.cjs. Stryker's command runner bills the full 'node --test <3 files>' invocation once per mutant, and node:test's default per-file process isolation forks a child process for each of the three files on every one of those invocations — pure fork overhead multiplied by a much larger mutant population. Fix: scripts/mutation-matrix.cjs COVERED.frontmatter now declares isolation: 'none', and .github/workflows/mutation.yml passes --test-isolation=${{ matrix.isolation }} (defaulting to 'process' — i.e. unchanged behavior — for the other 8 shards, which were not individually audited for cross-file state leakage under shared-process execution). Measured locally via node:test's run() API on the exact 3-file set: isolation:'process' took ~593ms vs isolation:'none' ~478ms for the same 392 passing assertions. The true CI-shard number can only be confirmed on the GitHub Actions run (Stryker cannot run locally, and 'node --test' is hard-blocked in this environment). Refs #3881 * test(#3881): register the vendored-parser tests in the frontmatter mutation shard stryker.config.mjs's own rule ("Keep this list in sync with the tests arrays in scripts/mutation-matrix.cjs COVERED") was violated: #3881 grew src/frontmatter.cts from ~825 to 1496 lines but its new tests (tests/feat-3881-yaml-parser-consequences.test.cjs, tests/frontmatter-golden-parity.test.cjs, tests/frontmatter-roundtrip.property.test.cjs, and +167 lines in tests/frontmatter.test.cjs) were never added to the frontmatter shard's tests array, so Stryker's mutants in the new vendored-js-yaml adapter had nothing constraining them. PR #3888 measured 55.8% against the 65 floor (748 killed / 593 survived / 17 timeout) and the shard was separately cancelled at 15m04s against the 15-minute per-shard cap. Registers all four files (each earns its slot on evidence of a unique constraining assertion, documented inline), gives the shard a measured/projected 180-minute budget via a new per-module timeoutMinutes field threaded through mutation.yml's job-level timeout-minutes the same way isolation is threaded, and removes the prior isolation:'none' override (re-measured at this file-set size, its savings are within run-to-run noise, not worth the unaudited cross-file-state-leakage risk).

Tom Boucher	a638ca4332	enhance(#3882): stop sentinel phases skewing estimation calibration (#3893) ... * test(#3882): failing-first rows for sentinel phases skewing calibration Adds A1a/A1b/A2/A3 to tests/estimate-calibrate.test.cjs, the module's existing test file, rather than a new bug-NNNN file. collectCalibrationSamples (src/estimate-cli.cts:206) does a raw readdirSync over .planning/phases and never applies isSentinelPhaseId, so a sentinel phase (milestone 0 or 999) carrying a PLAN estimate / SUMMARY actuals pair contributes a phantom calibration sample. computeCalibration is median-based, so a single 50x outlier among three samples leaves the factor unmoved — asserting "the factor is unchanged" against one sentinel would pass on the broken code for the wrong reason. Each row instead asserts the WHOLE computed CalibrationResult object (factor, applied, confidence, sampleCount, clamped) for a sentinel-free project against its sentinel-injected twin: - A1a: one sentinel flips applied false->true and confidence low->med on phantom evidence (calibration switches on with zero real signal). - A1b: two sentinels corrupt the factor itself (1 -> 3, clamped false->true). - A2: the sentinel's own sample is verified absent from the returned list. - A3: the two genuine phases still contribute their own unchanged samples (regression pin — stops A1/A2 passing by filtering everything). Verified RED on today's code (node tests/estimate-calibrate.test.cjs): A1a/A1b/A2 fail with the exact differing objects; A3 and all pre-existing rows in the file remain green (no collateral). Refs #3882 * feat(#3882): route phase enumeration through its owner and name the sentinel axis Task 1: collectCalibrationSamples (src/estimate-cli.cts) hand-rolled a raw readdirSync over .planning/phases, treating every directory (including sentinel phases, milestone 0/999) as a completed phase and feeding phantom PLAN/SUMMARY samples into the estimation calibration factor. Routed through the existing owner, listMilestonePhaseDirs(phasesRoot) with no cwd -- already 'all milestones, sentinels excluded', exactly the combination this caller needs; no new API was required for this half. It now also surfaces the scope discriminator: an unreadable phases directory throws PhasesUnreadableError instead of silently returning zero samples, and cmdEstimateCalibrate reports it via a new ERROR_REASON.ESTIMATE_PHASES_UNREADABLE instead of persisting a phantom empty calibration document. Task 2: added listAllPhaseDirs(phasesDir, { includeSentinels }) to src/phase-locator.cts -- the one genuinely missing axis: 'physical set, sentinels INCLUDED'. includeSentinels has no default and is required, so a call site cannot obtain sentinel-inclusion by omission (compile-time refusal, not just documentation). Mirrors listMilestonePhaseDirs's absent/unreadable scope handling. Task 3: migrated the two exemptions whose written reason maps cleanly onto 'physical set, sentinels included' -- cmdRoadmapAnalyze's _phaseDirNames (src/roadmap.cts) and cmdInitMilestoneOp's diskPhaseDirs (src/init.cts), both heading->directory lookup indexes. Left the rest: archivePhaseDirectories's own body has no readdirSync to migrate (its callers already resolve dirs before calling it, and both current callers deliberately EXCLUDE sentinels -- migrating it would be an unauthorized behavior change, not an API swap); cmdValidateHealth's exemption is vestigial (its actual physical-set sweep already lives in planning-snapshot.cts's buildAllPhaseDirNamesField, a pre-existing near-duplicate of the new axis, flagged as a finding, not restructured); cmdPhasesClear/cmdMilestoneComplete/cmdVerifySchemaDrift/detectHasPriorPhases/detectUiPhaseActive want a different combination (sentinels excluded, or a single-phase lookup) and are unaffected. Task 4: detector 2 (sentinel literal) is untouched and retained. Removed exemption entries only for the two migrated call sites; every other function-scoped exemption is preserved. Guard exits 0. Refs #3882 * refactor(#3882): delegate the snapshot phase-dir scan to its owner buildAllPhaseDirNamesField duplicated listAllPhaseDirs's own readdirSync + directory-filter + absent/unreadable handling — the 'one implementation per rule' defect ADR-3473 SS8.3 names, introduced by this branch's own #3882 work.

Tom Boucher	ddde001af6	enhance(#3873): the STATE.md schema — one owner, generated artifacts (#3880) ... * test(#3873): failing-first locale parity, plus tripwires for what must not move Pins ADR-3473 §8.8 at the artifact a reader actually sees. The English STATE.md reference carries a Status lifecycle section that is missing from all four translations — the section documenting the status enum whose clobbering is #3853. The test derives the heading set rather than hard-coding the missing one, and names the locale and the heading when it fails. Two tripwires that must pass today and after. The field-drift guard still catches a re-derived fallback ladder: §8.8 instructs deleting that script, and that instruction rests on a wrong premise about what it guards, so the test stops a future reader from deleting it on the ADR's word. And last_activity's label resolution is pinned to what ships today, because it is declared in one of the two tables this phase consolidates and not the other — the consolidation must not silently pick a side. The locale test buckets under docs rather than state, which is what it tests; that bucket is allowlisted with justification rather than folded into an unrelated docs suite. It reads only markdown, so it carries no allow-test-rule marker — a marker there would suppress nothing and would grow the unverified pool against its ceiling. Refs #3873 * feat(#3873): one schema owns the STATE.md key set, three tables become projections ADR-3473 §8.8. The key set was declared in four places that had to agree by hand and already did not: FIELD_CLASSIFICATION, FRONTMATTER_BODY_SOURCE, FRONTMATTER_KEY_TO_BODY_LABEL and buildStateFrontmatter's emit behavior. One frozen null-prototype schema now declares each key's type, enum, cardinality, source, preservation, body source, body label, accepted parse shapes and whether it is emitted unconditionally; the three tables are derived from it at module load. The projections are byte-identical to the literals they replace, key order included, and the parity tests compare against verbatim copies of today's tables rather than re-deriving both sides from the schema — a parity test fed from one source proves nothing, which is how a consolidation ships a changed policy under a green test. last_activity was the live disagreement: present in one table, absent from the other. The schema declares what ships today rather than the tidier answer, and a test pins it. The schema is a leaf module and owns the four field-policy types, re-exported from state-transition so existing importers are untouched — the same split health-diagnostic-types made to break a CJS require cycle. Refs #3873 * feat(#3873): generate the schema-derived regions, parity-check the prose tables ADR-3473 §8.8's generator half. gen-state-md-docs.cjs owns marked regions in the shipped template and all five reference docs, follows gen-features.cjs's fail-closed contract, and is wired into regen:derived and lint:generated-sync. The Status lifecycle section was missing from all four translations — the section documenting the status enum behind #3853 — and is now generated into every locale. Field cardinality is a new generated table: pure schema data, no prose, so nothing to lose. The Field-reference and Status-values tables are parity-CHECKED rather than generated. Their Purpose, When-populated and Matched-text columns are genuinely hand-translated per locale, and §8.8 itself says prose stays hand-translated; generating them from an English registry would overwrite four locales' translations on every write. The row set is checked against the schema instead, so a key added to one and not the other fails, which is what field drift actually means. Building that check found last_activity_desc undocumented in all five tables. Three keys the docs describe are absent from the schema — active_phase, next_action, next_phases. They are grandfathered by name, not by wildcard, so a fourth fails: a declared gap with a forcing function rather than a silent one. Refs #3873 * fix(#3873): declare what the parsers do, and close the shape-parity gap Two declarations in the new schema described intended behavior rather than actual — the defect class this epic exists to end, committed inside the epic. Both were caught by executing the parsers instead of reading their docstrings. current_plan.acceptedShapes claimed ['N', 'N of M']. Standalone, the hybrid shape errors; the path that looks like support is parseInt truncating '2 of 5' to 2 and discarding the rest. Narrowed to ['N']. The parser is deliberately NOT fixed here: that is #3784 and PR #3791 is already doing it. When #3791 lands this row must widen, and the shape test will go red until it does — the schema and the parser cannot drift apart quietly, which is what §8.8's checked-not- generated rule is for. STATUS_LIFECYCLE_ENUM claimed to be the closed set status can hold. normalizeStateStatus passes unrecognized prose through unchanged, so it is not closed at runtime. The seven members are the canonical values it maps onto; the docstring now says that and the test asserts the real lenient contract. Closes the acceptance item that a test asserts the parsers accept exactly the declared shapes: the check is table-driven over every row carrying acceptedShapes, guarded against passing vacuously on an empty set, and fails loudly if a future row has no registered driver. Adds the unwired-label throw and the fast-check property that every projection agrees with its schema row. Refs #3873 * fix(#3873): keep the shipped template's frontmatter first, and make row 27 able to fail The remote matrix caught 12 failures with one cause. Making the template's frontmatter a generated region wrapped it in its own yaml fence ahead of the markdown fence, so extractFileTemplate and readShippedStateTemplateBody — which both match the single markdown block — found the heading first, not the frontmatter. That breaks the contract every new project's STATE.md is created from: bug #21 and epic #1969 B8 pin that the File Template block starts with frontmatter and carries gsd_state_version. The markers now sit inside the single markdown fence, so the fence opens before the frontmatter and the region still ends ahead of the heading. Same layout as before this phase, with markers embedded rather than a second fence. Row 27 existed to catch exactly this and did not, because it was writer-seeded: it asserted against the generator's own output shape, so it passed on the broken template. It now parses the fence the way production does and was verified to fail against the broken shape before being trusted against the fixed one. A test that would not have caught the bug it exists to prevent is worse than no test. The emitted-attribution failure was separate and the fragment was the wrong remedy: gsd-core/templates/state.md self-attributes under a verbatim-copy identity rule, so a diff touching it needs no acknowledgment. Fragment deleted rather than left explaining nothing. Refs #3873 * docs(#3873): how to change the STATE.md schema The phase gate was right and my docs artifact was wrong. I listed lint:generated-sync as the second enablement step, which is a verification command dressed as one, and then claimed a one-step sequence owed no how-to. The real sequence is build:lib then regen:derived, and the ordering is a trap: the generator reads the COMPILED schema, so regenerating before building regenerates against the previous schema and commits artifacts that look plausible while disagreeing with the code just written. A reference table cannot carry an ordering dependency; that is what the how-to test is for. The page covers adding, changing and removing a key, every reason code the check emits and what to do about each, what is generated versus hand-translated and why the two prose-bearing tables are parity-checked instead of generated, adding a language, and the three grandfathered keys.

Tom Boucher	3b18eff388	enhance(#3872): what a command reports it wrote — the transaction diff (#3878) ... * test(#3872): failing-first regressions for what a command reports it wrote Pins ADR-3473 §8.7 at the consumer's output. state planned-phase advances current_phase on disk and never reports it, and reports progress.total_plans which reconcileReportedFields silently drops because it cannot resolve a dotted key against nested frontmatter. Both directions of #3818's own before/after diff, reproduced against the real CLI. Also pins the two properties the change must not break: a fully-failed patch still reports an empty updated array, which is what state.cts:607's success boolean depends on; and two content-identical writes differ in last_updated alone. That second one measured state_head NOT to be ambient — it is recomputed every write but only changes when git HEAD moved — so the provenance exclusion is a one-element set, with a companion test pinning that state_head does change when HEAD moves. Refs #3872 * feat(#3872): derive what a command reports from the transaction diff ADR-3473 §8.7. reconcileReportedFields compared the transform's own output against persisted bytes and then filtered what preservation had restored by its FIELD_CLASSIFICATION policy. Both are replaced by one comparison of persisted against the pre-write state the transaction already holds, surfaced to the command through the same caller-allocates out-param idiom divergedFields established. Both of the old directions fall out of that single comparison: a field the transform reported but the pipeline discarded is persisted-equals-snapshot and drops out, and a field nobody reported but the write moved is different and appears. The classification filter is deleted, not relocated — no policy test remains anywhere in the reporting path. Reporting is at dotted-leaf granularity, enumerated from the progress.* rows FIELD_CLASSIFICATION already declares rather than by walking user data to arbitrary depth. That closes a live defect: plannedPhaseCore already pushed progress.total_plans and reconcileReportedFields silently dropped it, because a flat hasOwnProperty cannot resolve a dotted key against nested frontmatter. Current Position was lost the same way and is fixed in the same place. The exclusion is one field, last_updated, and it is by provenance rather than by classification: it is the only field measured to change on every write regardless of content. state_head was measured NOT to qualify — it is recomputed every write but only changes when git HEAD moved. Without that exclusion state.patch's success boolean, which is updated.length > 0, would be permanently true and a fully-failed patch would report success. Refs #3872 * fix(#3872): cover the matrix, and close a prototype-chain read the coverage found Review found 20 of 29 test-matrix rows uncovered. Covering them found two real defects rather than merely documenting the intended behavior. bodyLabelFor read FRONTMATTER_KEY_TO_BODY_LABEL with a bare bracket index on a plain object literal, so a field named __proto__, constructor or toString resolved to the inherited prototype member and leaked a non-string value into the updated array. Fixed with an own-property check, mirroring the discipline resolveFrontmatterPath already had. The security-relevant matrix row proved it before the fix. applyPostSyncPreservation still carried its own inline copy of the value comparison alongside the new stateFieldValuesDiffer, which is two live copies of one rule introduced by the epic that exists to remove them. Routed through the single owner. Adds the fast-check property that a field appears iff its persisted value differs from the snapshot, the string-versus-number representation boundary, dotted paths into missing parents and into scalars, deleted and added keys, and the preserve-if-placeholder pair that proves no classification test survives in the reporting path. Refs #3872 * docs(#3872): document the transaction diff on the write path The updated array's contract belongs where the write path is described. States the iff rule, leaf granularity, the single provenance exclusion and why state_head is deliberately not one, and closes with the consequence a reader actually needs: these arrays are longer than they used to be, because they used to under-report. Refs #3872 * fix(#3872): a derived leaf materializing is not a change the caller made The remote matrix caught 17 failures with two causes. The substantive one is that progress is source: disk, and the disk cannot change during a STATE.md write — the write only touches STATE.md. So a progress block appearing where the snapshot had none is the scanner populating a document that had never been synced. The bytes moved; nothing the caller did moved them. That is the same shape as last_updated one level up, so the provenance rule is generalized rather than special-cased: a field appears iff its persisted value changed for a reason attributable to this write's action, and two cases are not attributable — a field stamped unconditionally on every save, and a declared derived leaf materializing from a source that did not change. Crucially this does not consult the preservation policy, so the filter §8.7 deleted stays deleted; it uses the declared leaf set to know which keys are derived. This had a second production consumer the earlier review concluded did not exist: cmdStatePlannedPhase gates publishStateContract on updated.length, and its own inline comment predicts exactly this failure. A no-op call was publishing state.json. advancePlanNoOpDoesNotPublish genuinely encoded pre-§8.7 behavior and moves. E2 and E6 had carved out total_plans as reportable-on-materialization, an error introduced earlier on this branch rather than a pre-existing pin, and are corrected with it.

Closed with a literal allowlist and a :(literal) pathspec, two independent layers. - an apostrophe inside a heredoc nested in a command substitution is an unterminated quote and a hard syntax error at runtime, not just under bash -n. - an empty plan no longer reports success unconditionally: the guard is re-run without the hold to tell "next is clean" from "everything is held", the commonest holder being the sweep PR from the previous run, which touches exactly the fragments it proposed to delete. - a branch pushed by a run that died before it could open the PR wedged every later run on a non-fast-forward push; re-pointed under a lease instead. - a guard crash in plan mode no longer reads as "nothing to sweep".

Tom Boucher	1863f5569c	enhance(#3871): the state transaction — mandatory snapshot, open()/rebuild() (#3874) ... * test(#3871): failing-first regressions for the dropped curated progress block Pins ADR-3473 §8.6 / #3756 at the consumer's output: state record-session and state add-decision on an archived-milestone project drop the curated progress frontmatter entirely, exit 0, and report nothing. Reproduced against the real CLI before writing the tests, not inferred from the issue text. Also adds the unit-level probe that applyStatePreservation's preserve-always row is inert on a resyncing write, and an over-preservation guard that an empty project is never inflated. Refs #3871 * feat(#3871): make the STATE.md pre-write snapshot mandatory via open()/rebuild() ADR-3473 §8.6. StatePreservationInput's nullable preFm and the always-present preFmSnapshot were the same extractFrontmatter call, one of them nulled on resync — a policy flag baked into a snapshot. Both collapse into a single StateTransaction whose snapshot cannot be absent: openStateTransaction() applies preservation, rebuildStateTransaction() does not, and both carry the snapshot because the reporting phase needs it either way. An absent snapshot is now a construction failure; an empty one stays legal, because that is what a document with no parseable frontmatter honestly has. writeStateMd requires a rebuild transaction, which types ADR-3408 §8.3's closed exception list at both call sites (state sync, health --repair) instead of matching them as strings in a ratcheted baseline. Fixes the dropped curated progress block: an all-zero or absent derived total set is an unmeasured scan, not a measurement, so the curated block stands. Also fixes two defects surfaced while building — preserve-always reported a mutation even when it restored an identical value, and it re-entered the curated object by reference, which would alias the snapshot the next phase diffs against. Refs #3871 * fix(#3871): close the three remaining subsumed defects and restore the arm the type does not replace Review of the first two commits found four things. The guard shrink deleted the seam-bypass axis whole, but only its writeStateMd( arm became redundant. Its other arm catches a call site re-assembling syncStateFrontmatter + applyPostSyncPreservation instead of the owned composition, which the transaction type does not make unrepresentable and which #3469 found live. Restored as findCompositionBypasses, terminal rather than ratcheted. Three of the four issues this phase claims were untouched. All three are the epic's own shape and are fixed at the seam: current_phase_name is reasserted from the curated value when the caller names none, and cmdStateJson stops carrying a hand-maintained list parallel to FIELD_CLASSIFICATION and projects it instead. The construction failure that is the point of this phase had no test. Every enumerated matrix row now has one, including the measured-versus-unmeasured coercion boundary and a seeded property that no curated key is ever dropped. ADR-3473 §8.6 said the guard 'keeps only its raw-write check'. Verified against next: there was no raw-write check, and four other checks it does not name. Amended in place with the evidence. ARCHITECTURE.md separately advertised a preservation policy the code had deleted. Refs #3871 * fix(#3871): do not let the unmeasured-scan rule block an explicitly-requested resync The remote matrix caught over-preservation, the failure this phase's own negative space says must not happen. state update Progress re-derives the block from the body the caller just rewrote; on a project with no phase dirs the derivation yields zero totals, the unmeasured rule read that as 'the scan measured nothing', and the stale curated percent was restored over the resync the user asked for. preserve-always already said what the missing condition was: never overwrite unless the caller explicitly names this field. explicitProgressField carries it and is derived from shouldResyncStateProgress, not set by hand at a call site, so it cannot drift from what the caller asked for. Two defects found in the same mechanism and fixed with it. readModifyWriteStateMd enumerates its option keys, so a new option was silently dropped rather than rejected. And the raw-write axis captured its first argument up to the first comma, which lands inside a nested path.join, so a write to a STATE.md literal was invisible to it — the prove-it-can-fail test caught that one immediately. No test assertion was weakened; all three frontmatter rows encode #3242, #1969 B3 and #1972 and stand unchanged. Refs #3871 * docs(#3871): record why the raw-write check is kept, not why it was named The amendment justified findRawStateWrites as 'written because §8.6 requires it to exist', which is cargo-culting the contract and would have been the wrong reason to keep anything. The real reason is that writeStateMd acquires the STATE.md lockfile and a raw fs.writeFileSync acquires nothing, so this is a lock bypass and lost-update is the #500/#905/#1230 family — and after this phase it is the one reachable path into the file that nothing else covers. Also records why ADR-3408 §8.6's deletion of the 'clear' policy is not the precedent it looks like: 'clear' was dead vocabulary in a closed enum, this is coverage of a reachable path.

Tom Boucher	fb2d122d7f	feat(#3841): assert gsd-tools identity on every state-mutating verb (#3848) ... * feat(#3841): assert gsd-tools identity before any state-mutating verb only this package publishes. The path-based branches — a project-local install, a runtime config directory — had no such guarantee; they trusted their configured location. This closes them. Mechanism: once resolution finishes, and before any verb runs, the preamble probes the tool it picked with `runtime-identity --raw` and matches the answer with a shell `case` pattern ANCHORED to the start of the compact payload (`{"packageName":"@opengsd/gsd-core"`). An unanchored substring match accepts the decoy `{"packageName":"get-shit-done-cc","note":"@opengsd/gsd-core"}`, which any colliding package could publish. The outcome is exported as the two-valued `GSD_IDENTITY_STATUS` (`ok`/`unverified`), so the gate is asserted on a VALUE rather than on warning prose. Rollout is warn-then-fail per the #3146 ruling: `unverified` prints one line naming BOTH causes and continues, because `no_identity_verb` cannot tell a foreign package from an `@opengsd/gsd-core` older than the verb, and at rollout the old-version case is the common one. The blocker was byte budget, not design. The preamble is inlined into 112 shipped files and several sat within single-digit bytes of frozen ceilings (`gsd-verifier.md` 16 bytes, `gsd-executor.md` 33, `execute-phase.md` 234); a first attempt broke five of them. What made room was collapsing the resolver's twenty near-identical `elif [ -f … ]` arms into one candidate-list helper (`_gsd_at`), which buys far more than the assertion costs. The preamble is now 2,624 bytes against 4,500 — a net 1,876 bytes SMALLER per inlined file, so every capped file moved away from its ceiling rather than toward it. No cap raised, no size-budget exception added, no override token emitted. Resolution order, every runtime-home probe, the `unset -f gsd_run` re-source fix, the fail-closed `exit 1`, and the `CLAUDE_ENV_FILE` persistence are all preserved byte-for-byte in substring terms; the snippet still begins with `_GSD_SHIM_NAME=` and still ends with `fi`, which the parity extractors anchor on. `gsd-core/references/gsd-run-resolver.md` is re-synced byte-equal. Also fixes two stale claims found in passing: CONTEXT.md and FEATURES.md both described an `[ -x ]` guard as the load-bearing re-source defense. That guard was tried and REMOVED in #3831 — it rejected the bare function name, fell through every branch, and hit `exit 1`, which kills a sourced caller's shell. `unset -f gsd_run` is the actual mechanism. Refs #3841 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3841): pair the anchor's brace by requiring a closed identity payload The matrix went red on `tests/new-project-mvp-prompt.test.cjs` — "new-project.md has unbalanced braces: net depth 2" — plus a knock-on report from its parent `bug #1516` describe, which is the same failure counted once at the child and once at the block. Root cause: that guard (:182-189, mirroring #3784 bd53925f) walks characters and increments on `{`, decrements on `}`, with no awareness of shell quoting. It scans `new-project.md` PLUS every `new-project/steps/*.md`, and both `new-project.md` and `steps/auto-mode-config.md` carry one inlined preamble copy — hence net 2 from a snippet that was off by exactly one. The unpaired brace was the `{` inside the single-quoted `case` pattern of the identity anchor, which is correct shell and invisible to a text scanner. Fix in the snippet, not the guard. The pattern now anchors at BOTH ends: `'{"packageName":"@opengsd/gsd-core"'*'}'`. That balances 51/51 with a brace that does real work rather than a cosmetic pair — a truncated payload whose prefix matches now fails too, where before it verified. Safe for any future additive field: a JSON object's own closing brace is always the last character, whatever type the last value has, which is pinned by two negative-space tests (a nested object and an array-valued last key must both still verify). Cost: +3 bytes, against the 1,873 the resolver fold already gave back. The alternative considered and rejected was dropping the literal `{` for a `?` glob. It balances too, but weakens the anchor from "must be an opening brace" to "must be any one character", and the anchor is the entire point. Two guards added so this cannot recur silently: - runtime-launcher-parity (F0) pins brace balance at the SNIPPET, so the next edit to that pattern fails on the file it broke instead of surfacing three files downstream in a test whose name mentions neither the launcher nor this issue. It also asserts depth never goes negative, since a `}` preceding its `{` nets to zero while being unbalanced at every prefix. - runtime-identity gains behavioral truncated-payload and trailing-garbage fixtures, so the added `}` is proven load-bearing rather than merely present. Verified: snippet 51/51 braces; new-project combined net depth 0; the seven other preamble-bearing files with nonzero depth are unchanged from merged next (their own prose, not the preamble, and not in any guard's scan set); all 112 inlined copies and the resolver reference re-synced byte-equal; sync:launcher idempotent on the second run.

Tom Boucher	63abcface9	feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools (#3831) ... * feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools The predecessor package get-shit-done-cc publishes a colliding gsd-tools bin whose phases.clear DELETES where this package's ARCHIVES, and both print success-shaped output against a gitignored .planning/ -- which is how #3129 cost a user 43 phase directories with no error and nothing recoverable from git. The launcher's PATH branch now resolves gsd_run, published only by this package and self-locating via its own symlink chain to the sibling shim, instead of the colliding gsd-tools. A foreign handler becomes unreachable from PATH, and when no gsd_run is reachable the resolver fails closed rather than falling back -- that fallback was the vulnerability. This is smaller than the branch it replaces, which matters: the preamble is inlined into 113 shipped files and agents/gsd-verifier.md sits 2 bytes under a red-line size cap. unset -f gsd_run leads the preamble so a re-source is idempotent. Without it, command -v finds the shell function, returns a bare name, and the resolver falls through to an exit 1 that kills a sourced caller's shell. Adds gsd-tools runtime-identity, a manual diagnostic reporting this runtime's package coordinates over the baked package-identity (#498) and readHostVersion, with a strict total classifier: only a JSON object with an exact packageName verifies, since JSON.parse admits 0/"str"/[]/null/true. An inlined identity assertion was built and reviewed first, then withdrawn -- it breaks five frozen size ceilings and no assertion fits in 2 bytes. Closes #3146 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3146): stop sync:launcher relocating a deliberate preamble placement Pre-existing defect, surfaced by this PR because sync is a no-op unless the snippet content actually changes. transformFile inserts the preamble into the first block that CALLS gsd_run, but gsd-core/workflows/explore.md deliberately places it in a bootstrap-only block that DEFINES gsd_run without calling it -- its own comment explains why: declining the research offer must not leave Step 5's commit call unbootstrapped. Stripping empties that block of calls, so the preamble migrated forward and broke the define-before-use invariant tests/explore-command.test.cjs pins. Reproduced on a pristine origin/next checkout with the base snippet and base file, so this was not introduced here. The insertion target now honours a block that already carried the preamble, falling back to the first calling block for files that have none yet. Adds a behavioral regression test over a two-block fixture. Also updates three runtime-launcher-parity tests that pinned the removed PATH fallback to gsd-tools. Their intent is preserved -- the PATH stub is renamed gsd_run so it is reachable by the new resolver, and the RUNTIME_DIR-wins test still asserts the stub is never invoked. Fixture shebangs move to an absolute /bin/sh, because the fixture PATH is deliberately restricted and #!/usr/bin/env sh could not resolve.

Two PRs adding differently numbered features still collide on the TOC, so renumbering alone does not make a branch safe. This branch alone was renumbered 165 -> 166 -> 167 -> 168 across successive rebases. Adds a CONTRIBUTING section stating the practice: allocate the number last, never pre-emptively renumber, take max+1 after a rebase and update the TOC in the same commit, and never renumber someone else's section. Fork contributors are told explicitly they may leave the number to a maintainer at merge rather than chasing the counter. Agents are told to lease the allocation and to include the file in their published touched set.

Tom Boucher	fb9823e1e1	fix(#3689): refuse a ledger write when the rendered table disagrees with its JSON (#3828) ... * test(#3689): failing-first coverage for the ledger table/JSON agreement guard `.planning/WINDOWS.md` renders its markdown table from the fenced JSON that is its source of truth, but nothing checks the two still agree before a write overwrites the table. `windows append` / `waive` / `fixed` therefore discard a drifted cell silently, and erase a table-only row entirely, both at exit 0. Adds to tests/broken-windows.test.cjs: - five refusal cases that fail today, covering all three write commands, a drifted cell, a table-only row, and drift on a non-first row; each asserts the typed reason via GSD_JSON_ERRORS and that the file is byte-identical after the refusal, so a guard that refuses only after writing cannot pass - six anti-tightening pins that must stay green: an agreeing ledger, the first-write ENOENT path, #2893 trailing-prose preservation, #3657 3-backtick fence tolerance, escaped pipes and backslashes in a description, and the zero-entry placeholder table - a fast-check property pinning the round trip the guard depends on — extractTableRegion(renderLedger(l)) === renderTable(l.entries) — because a false refusal on a clean ledger would be worse than the bug Fixtures are built by running the real CLI and then perturbing only the table, so frontmatter and JSON stay consistent and the pre-existing counts cross-check still passes; a hand-written ledger would pass these for the wrong reason. Refs #3689 * fix(#3689): refuse a ledger write when the rendered table disagrees with its JSON `.planning/WINDOWS.md` renders its markdown table from the fenced JSON that is its source of truth, and `writeLedgerAtomic` regenerated that table on every `windows append` / `waive` / `fixed` without ever checking the two still agreed. A hand-edited cell was silently reverted; a row that existed only in the table vanished entirely. Both at exit 0, with nothing on stdout to say so. The write seam now compares the on-disk table against `renderTable(<entries parsed from the on-disk JSON>)` before regenerating anything, and refuses with a typed `windows_ledger_table_drift` error naming the drifted row ids and the remedy. Because the check sits at the single write seam, all three commands inherit it, and the file is left byte-identical on refusal. Deliberately not enforced in `parseLedger`: hardening the read would break `windows status` and the ship gate on exactly the ledgers an operator needs to inspect to diagnose the drift. Two hazards handled explicitly, both discovered in review of the first draft: - The pre-image read now distinguishes ENOENT from every other errno, per the #1950-H2 fail-closed-on-unreadable invariant `readLedgerOrNull` already honors. A bare catch would have let an unreadable pre-image skip the guard and write anyway. - Both the entries baseline and the table extraction pass the pre-image's own frontmatter `total_count` to `locateJsonBlock`. Without that hint the no-expectation fallback binds to the LATEST fenced JSON array in the file, which is the operator's prose block whenever that prose contains one — the exact case #2893 exists for — refusing every write on a ledger that never drifted. A regression test covers it. Also extends the CONTEXT.md Broken Windows Ledger glossary entry: the table is a third projection of the same source, cross-checked at the write seam, and the frozen REASON enum gains WINDOWS_LEDGER_TABLE_DRIFT. Fixes #3689 * fix(#3689): bind prose preservation to the pre-image's own ledger block Found while reviewing the table drift guard: the #2893 trailing-prose preservation in `writeLedgerAtomic` passed `ledger.total_count` — the POST-mutation count — as the disambiguation hint for a lookup over the PRE-image. On an append the pre-image holds N entries while the hint says N+1, so the hint can never match and `locateJsonBlock` falls through to its last-array-shaped-span fallback. When the operator's trailing prose itself contains a fenced JSON array — the ordinary case #2893 was written to protect — that prose block wins the fallback. The preserved region is then computed from the prose fence rather than the ledger fence, and everything between them, including the operator's own text above the array, is silently dropped on the next write. Reproduced against the real CLI: a prose block reading "Operator notes above the array, IMPORTANT DO NOT LOSE THIS TEXT." plus a fenced 3-element array came back empty after one `windows append`. Both the prose lookup and the drift guard now share one pre-image-derived `preImageExpectedTotal`, taken from the pre-image's own frontmatter, so they bind to the same and correct block. The existing trailing-prose regression test is strengthened to assert the prose survives byte-for-byte rather than merely that the command exited 0 — asserting only the exit code is why this was invisible. Refs #3689 * fix(#3689): anchor table extraction on the header row, not a line-prefix scan Independent review found the drift guard could brick a ledger nobody had hand-edited. `validateDescription` accepts a description containing a raw newline, and `renderTable`'s cell escaping covers backslash and pipe but not newlines — so such a description renders a row that physically spans two file lines, the second of which does not begin with `|`. `extractTableRegion` bounded the table by walking backward over the contiguous run of `|`-prefixed lines, so it stopped at that split. In the common case where the row's tail is the last line before the fence it returned null, and every subsequent append/waive/fixed was refused with "table region could not be located" — permanently, with no CLI recovery path, on a ledger that never drifted. A false refusal is worse than the bug this guard exists to fix. The region is now anchored on the header row `renderTable` always emits, running from its last line-start occurrence to the end of the pre-fence text. The boundary is the fence rather than a line prefix, so a multi-line row is captured whole, re-renders byte-identically, and compares equal. The header literal is hoisted to one constant both `renderTable` branches and the extractor share, so the two surfaces cannot drift apart. Deliberately unchanged: `cell()` and `validateDescription`. The cosmetic corruption a newline causes in the rendered table is pre-existing, and either escaping it or rejecting the input would change what existing ledgers render to or what input is accepted. Also closes a coverage gap the standards review raised: the non-ENOENT pre-image read branch — the one that stops an unreadable file from bypassing the guard — now has a behavioral test that injects EACCES by monkeypatching `fs.readFileSync` for that one path and restoring it in a `finally`, never by `chmod 0o000` (root ignores mode bits, so that would pass with zero coverage). The #3689 property generator no longer strips newlines out of descriptions, which is why this was invisible to it. Refs #3689 * chore(changeset): backfill PR number for #3689 fragment * chore(changeset): backfill PR number for #3689 fragment * fix(#3689): terminate the header scan when the match sits at index 0 `extractTableRegion`'s backward search for the table header could loop forever. On a rejected match at index 0 it set `searchFrom = idx - 1`, i.e. `-1`; `String.prototype.lastIndexOf` clamps its position argument into `[0, length]`, so the next iteration searched from 0, found the same match, rejected it identically, and set `-1` again. The loop made no progress. Reachable only through the exported `extractTableRegion` — `writeLedgerAtomic` reaches it after `parseFrontmatterStrict` has already succeeded, so the candidate region begins with the `---` frontmatter fence and a match at index 0 is impossible. Latent rather than live, but an exported `for(;;)` that can fail to advance is not something to ship. Confirmed by running the pre-fix compiled function on `TABLE_HEADER_LINE + 'X\n' + <a valid json fence>` as a backgrounded child: it was still alive after five seconds having printed nothing, and had to be killed. Post-fix the same input returns `null` promptly — correct, since the sole header occurrence fails the end-of-line test and no valid header exists. A regression here would stall the suite rather than fail it, so the new test also asserts the returned value rather than relying on termination alone. No wall-clock assertion is involved. Refs #3689 * test(#3034): publish the lane trace before the done-file that releases dependents `preservesSelectionOrderParallelDespiteCompletionOrder` forces a reverse completion order with a dependency chain rather than sleeps: each stub lane waits on `done-<dep>` before finishing. It then ended with touch "$RUN_DIR/done-$slug" echo "end:$slug" >> "$TRACE" Those are two unsynchronized operations in separate shell processes. A dependent's `wait_for_file` unblocks the instant the upstream's `touch` lands, but the upstream's own `echo` has not necessarily run — so if the upstream is descheduled between the two, the dependent can run its whole body and append its `end:` line first. The done-file was published before the state it signals. Observed on the remote runner as `[end:claude, end:codex, end:gemini]` where selection order demands `[end:claude, end:gemini, end:codex]`. The failure was in the fixture's own self-check, before it reached the assertion #3034 exists to make. Not a flake and not a wall-clock margin: this branch passed the full suite twice at 14f494644 and 90c5d7a03, and the only delta in the failing run was one added test in tests/broken-windows.test.cjs — an unrelated module. Adding load elsewhere in the suite was enough to invert it, which is what a real race does. Swapping the pair establishes a genuine happens-before: anything a dependent can observe is written before the file that releases it. A comment records why, so the order is not tidied back. The production path is unaffected and was independently confirmed correct — `invoke_reviewers` joins every lane with `wait`, then aggregates by iterating DISPATCH_SLUGS in selection order, reading per-slug result files. It consumes no completion-order signal at all. Refs #3034 --------- Co-authored-by: sim <sim@local>	2026-08-24 17:43:25 -04:00
Tom Boucher	a84f756303	fix(#3078): sweep all-spent ack fragments on next, name the collision remedy (#3823) ... * fix(#3078): sweep all-spent ack fragments on next, name the collision remedy `guard-no-ack-on-next` only ever watched the legacy tests/emitted-drift-ack.json. #2914 exempted the fragment directory on the premise that a persisting fragment "cannot conflict with any other PR". Fragments do not share a FILE, but they do share a PATH KEY SPACE, and a path claimed by two sources is a hard failure in the same script -- so a fully-spent fragment on next owns keys it can no longer gate, and the next PR to grow one of those paths can declare it neither there (spent) nor in its own fragment (duplicate). Measured at the sweep: 45 fragments owning 403 paths, up from 13/272 at triage 19 days earlier. - `assertNoAllSpentFragments` fails a fragment only when EVERY surviving entry is spent against the copy at HEAD^, so a partially spent fragment -- and the re-arm-by-appending route #2639/#2993 ship on -- keeps working. - `ackProse` duplicates the gate's zero-width/whitespace stripping across the scripts-ship/tests-do-not line, bounded by a prose-parity test. - The guard job's checkout takes fetch-depth: 2; at depth 1 HEAD^ is absent and every fragment reads as brand-new, i.e. the guard passes vacuously. - The duplicate-ack error now names both resolutions, since the guard is post-merge by design and cannot stop the colliding PR. - All 45 spent fragments deleted, 0000-legacy-migration.json included, and the three tests that pinned its permanence corrected. Verification is the remote runner (gsd-test), not a local suite. Closes #3078 * fix(#3078): make the prose-parity test two-sided, cover the git seam, base on the pre-push tip Three review findings, all fixed: - The parity test was a tautology: it checked ACK_INVISIBLE against a hardcoded list matching its own definition, never against the gate. The gate's INVISIBLE and its reason normalizer (hoisted out of diffEmitted as normalizeAckReason) are now exported for that sole purpose, and the test sweeps 0x00-0xFFFF against both surfaces. Mutation-checked: adding a codepoint to one side and not the other now fails. - resolveBaseRef, readFragmentAtRef and assertUsableBaseRef had zero direct coverage -- the tests reimplemented the git reads in a local helper, so the ls-tree-vs-show discrimination, the root-commit fallback and the option-injection guard were never executed. All are exported and tested against real temp repositories now, plus an end-to-end --base-ref subprocess. - HEAD^ is not 'the state of next before this push'. The default branch allows REBASE merges, so one push can carry N commits, and a 2-commit rebase-merge whose first commit adds a fragment would be told to git rm it on the very push that introduced it. CI now passes github.event.before via --base-ref and fetches it explicitly; HEAD^ remains only the local fallback. Also adds the safe.directory guard every other git call in this repo carries (#2767), and stops naming the deleted migration fragment by filename in CONTEXT.md, which tripped lint-removed-but-needed. Refs #3078 * fix(#3078): keep the fragment directory alive after the sweep empties it Sweeping every fragment leaves the directory untracked, and check-glossary-refs then fails: CONTEXT.md references tests/emitted-drift-acks, which no longer exists. The empty directory IS the intended steady state, so it has to survive its own remedy. Adds tests/emitted-drift-acks/README.md documenting the create/use/delete lifecycle where a contributor actually meets it, matching the existing tests/qa/smell-acks/README.md precedent. Every reader filters on .json, so the README is invisible to the gate. Also sweeps #3809's ack fragment, which the rebase onto origin/next brought in and the new guard immediately reported as all-spent -- its own remedy applied. Refs #3078 * fix(#3078): guard the added tests' git calls, drop a second fragment-existence pin Both defects surfaced by the remote runner (linux-node24, 4/37445 failed). - The new --base-ref E2E test ran `git rev-parse HEAD` against the checkout without the #2767 safe.directory guard. The runner mounts the repo at a path owned by another uid, so git refused every operation there with 'detected dubious ownership'. Every git call the new tests make now names its own specific directory as safe, via one local helper, mirroring safeDirArgs in helpers/emitted-runtime.cjs. - tests/agent-tracked-source-rule.test.cjs pinned the existence and contents of the 3645 and 3409 ack fragments. That is a merged PR's paperwork, not live behavior: once the growth is in next's baseline the acks are spent and this PR's guard sweeps them. The third assertion pinned the hand-appended workaround for the exact collision #3078 removes. Deleted; #3645's real protection is the two behavioral tests above it, untouched. Also restores #3809's ack fragment, which merged one commit before this branch. Deleting an ack in the same window as its introducing PR races any consumer whose baseline predates it -- the runner's container proved it, resolving origin/next to 8ed105c8a where the file is still 13847. The backlog sweep is this PR's scope; that fragment is left for the guard's own first run. Adds the rule to the fragment README so the class stops recurring. Refs #3078 * test(#3078): derive the E2E guard expectation from the fragment inventory The --base-ref E2E test asserted exit 0 while passing the checkout's own HEAD as the base ref. HEAD-as-base makes every present fragment byte-identical to itself, so all of them are trivially all-spent and the guard correctly exits 1. The test only ever passed because the directory happened to be empty when it was written; restoring #3809's fragment made it fail. The script was right and the test was wrong. The degenerate base ref is kept deliberately -- it is what makes 'spent' trivially true and therefore deterministic -- but the expectation is now derived from listFragmentFiles() at runtime: zero fragments means exit 0 and the no-survivors line, N fragments means exit 1 with every name and its git rm. Proven state-independent by running the suite with the fragment present, with the directory emptied, and with it restored. The option-shaped --base-ref rejection is split into its own test, unchanged.

Tom Boucher	107eb8c1d9	feat(#3753): run docs guards on the PR that changes the docs they read (#3787) ... A PR whose diff is entirely under docs/ runs zero tests, so a guard whose INPUT is shipped prose cannot protect the PR lane of the diffs it exists to check. Its only firing opportunity is after merge, on the shared branch -- which is how next went red on dacae9273 while the PR that caused it (#3746) was green on every check. The docs-lint job in .github/workflows/docs-required.yml -- an ALREADY-REQUIRED context -- now selects and runs the docs guards that read the specific docs files the PR changed. scripts/docs-guard-registry.cjs test file -> the docs paths it reads (63) scripts/select-docs-guards.cjs pure (changedPaths, registry) -> test files scripts/lint-docs-guard-registration.cjs drift guard, wired into lint:ci scripts/ci-test-scope.cjs is NOT touched -- `git diff origin/next --` on it is empty -- so #764's saving stands and its 21 pinning tests are untouched. Selection: exact path; trailing-slash directory prefix (boundary-checked -- docs/adrenaline.md does NOT match docs/adr/, which a naive startsWith gets wrong); and '*' for the 6 entries that walk docs/ generally or read a computed path. Unknown maps to '*' -- guessing narrow is how a guard silently stops running. Measured: a typo fix selects 6 of 63; docs/AGENTS.md selects 12; docs/COMMANDS.md selects 18. Four things this got wrong first, each found by an independent reviewer or by probe, and each having been asserted safe in a comment: 1. The registry started as a RULE in ci-test-scope.cjs's RULES, on the theory that classify()'s !codeChanged normalization made it inert. True for docs-ONLY diffs; false for MIXED docs+code diffs, where codeChanged is true and the normalization never runs: node scripts/ci-test-scope.cjs --files "docs/a.md src/semver.cts" with the RULE: 25 targeted_tests origin/next: 3 targeted_tests Category error: RULES is the scoped lane's input; a docs-guard registry is a lane manifest for a consumer that never calls classify(). Extracted; pinned by value. 2. The second attempt was a dedicated workflow with paths: [docs/**]. Such a workflow never reports on a non-docs PR, so it can never be a required context without hanging every non-docs PR -- and a non-required check does not block a merge, so the guard would have been advisory and #3753 unfixed. docs-required.yml already has no paths: filter, already supplies the required docs-lint context, already computes docs_changed, and already ran one docs guard gated on it. Generalizing that step needs no ruleset edit at all. 3. The registry and the drift lint were built from ONE path-segment heuristic, so both were blind identically -- and blind at the guard that motivated the issue. The reader-call regex required a character BEFORE its keyword, so a callee named exactly read( / load( / parse( / doc( / file( / content( could never match; and only an INLINE path.join(ROOT,'docs','X.md') argument was caught, missing the two-step-via-variable form -- the MAJORITY spelling -- plus template literals and concatenation. Detector 1 fired on 14 of ~450 files, so 35 genuine guards sat unregistered while the lint reported 0 violations, including cursor-reviewer (reads docs/COMMANDS.md, asserts .includes('--cursor')) and inventory-headings-countfree. The "accepted blind spot" this shipped with was the common case, not a fringe. 4. With detection fixed the true population is 115 files: 63 genuine guards, 52 incidental. Running all 63 in a REQUIRED check on a one-line typo fix is the cost #764 exists to avoid -- install.test.cjs is 7840 lines and reads exactly one docs file, docs/AGENTS.md, for its frontmatter. Dropping it reproduces the bug; running it for a typo elsewhere is waste. Hence the map. Then a second review round found six more, all fixed here: - fragment-single-edit-propagation.install.test.cjs was EXEMPTED as "overlay fixture only". False: it reads the real docs/registries/eos.json and asserts on a registry entry name, and reads the real ADR-0001 and asserts its H1. A docs-only PR touching either would have gone green and red next -- #3753 shipping again, from inside the fix for it. Now registered against both paths, and all 52 remaining exemptions were re-audited one by one. - The SUITES-collision guard compared RAW registry keys, but run-tests.cjs strips a leading `tests/` BEFORE its suite check. So it caught 'all' and missed 'tests/all' -- the only spelling that can actually occur, since every key carries the prefix. One typo would have run all 824 test files inside the required job. Now normalized the same way run-tests.cjs normalizes. - The lint failed OPEN on an unreadable tests dir or candidate file: 0 violations, ok:true. A guard that cannot read its input must never report success. - The exemption ratchet gated identity only, so a baselined file that later STARTED asserting on shipped docs stayed exempt silently -- 52 permanently blind files. The baseline now fingerprints the docs paths each exempted file references and fails when that set changes, naming what changed. - The exemption marker was still honored inside a multi-line template literal in the header window. The scanner now tracks template-literal and block-comment state. - `git diff --name-only | grep '^docs/'` silently dropped C-quoted non-ASCII docs paths, making docs_changed=false a green zero-guard check. Both call sites now pass -c core.quotepath=false. - The run step was gated on hashFiles(), which a force-committed .docs-guard-tests.txt would satisfy. The step now rm -f's both scratch files first and gates on an output it sets itself. Three empty states, deliberately distinct, because conflating them rebuilds #3753: an empty or malformed registry HARD-FAILS; docs changed with no guard covering them logs and skips; no docs change is already gated. The middle state must never be expressed as an empty --files-from, which prints `no tests in suite "all"` and exits 0 -- a green check that guarded nothing. With the current registry that state is unreachable, because the six '*' entries always match; the branch is kept as defensive handling for a future registry and says so. timeout-minutes: 15 bounds the required job against a hanging fork-supplied test; it had none. npm ci was added because the job never installed dependencies -- the previous single-file step got away without it, the registry does not. docs/contributing/docs-guard-registration.md documents the rule, following its sibling cross-platform-portability-rules.md, and CONTRIBUTING.md's CI Test Quality Checks table links to it. It is also load-bearing: without a docs/ file in the diff this PR would not have triggered its own lane, shipping an unexercised change to a required check. One unrelated fix, included because this PR surfaced it and CLAUDE.md forbids deferring a defect found while working. On this branch's first CI run, `full test (windows-latest, 24, shard 3/3)` was CANCELLED at exactly 30 minutes; tests were still passing 0.8s before the cancel, so it is a wall-clock timeout, not a hang, and a cancelled job reddens `Required tests`. The cause is not this PR's test file, which costs ~60ms. Shard composition is unstable: adding ONE file to the unit suite reshuffled 115 of 268 files between shards, and shard 3 drew a heavier mix. Underneath that is a real pre-existing defect. tests/ci-test-job-timeout-budget.test.cjs requires every lane's budget to be >= 1.5x its MEASURED cost -- "a lane that got slower must be re-budgeted, not excused" -- and its test-full entry recorded 19m from a windows-22 shard. That is stale. Measured on `next` with none of this PR's changes present: 26m18s (run 32614439702, windows-latest/24 shard 3/3), 23m36s and 23m17s on shard 2/3. So the lane costs ~26m and the 30-minute cap carried 1.14x headroom, not 1.5x. The gate had been out of compliance with its own rule; this PR was merely the file addition that reshuffled shard 3 past the cliff. Fixed as that file prescribes: measuredMinutes 19 -> 27 with fresh evidence, and test-full timeout-minutes 30 -> 45. The rule's minimum for 27m is 41; 45 is deliberately above it because the reshuffle means per-shard worst case moves run to run, and a budget pinned to the exact minimum would be re-breached by the next test file anyone adds. Only that one job's timeout changed; test.yml's scope, matrix and steps are untouched, so #764's saving is unaffected. Raising that cap let the Windows shard finish (28m45s, inside 45) and uncovered a real failure the 30-minute cancel had been masking: `new quick-task branch branches off origin/main (#2916)` died with `outcome=timed_out exitCode=null`, SIGTERM, at the 15000ms bound. tests/quick-branching.test.cjs:149 `runStep` runs a `#!/usr/bin/env bash` script executing MULTIPLE git commands, but was bound to GIT_TIMEOUT_MS (15000) -- the norm for a SINGLE git plumbing call. tests/helpers/timeouts.cjs already documents this exact failure and exists to fix it: HOOK_FANOUT_TIMEOUT_MS was created after PR #3285 recorded "outcome=timed_out exitCode=null at exactly the 15000ms probe bound while every other lane passed the same commit", and calls that "a bound sized for the wrong class, not a slow machine". Our failure is that case verbatim, so both sites move to the class norm rather than to a bigger number. The same class also failed on `next` itself 21 hours earlier -- run 32608945654, windows-latest/24 shard 1/3, `plan touching only src/ in a submodule project keeps worktree isolation ENABLED` -- where tests/worktree-safety.test.cjs:5845 `runGate` fans out to `git config --file .gitmodules` under a hardcoded 30000. Fixed too, since it is a defect in the tree regardless of which branch surfaced it. A survey of the whole tests/ tree found the same class-mismatch at further bash fan-out sites bound under 60000ms, and the maintainer approved sweeping them rather than leaving them latent to surface the same way one at a time. 16 fan-out sites across 16 files now use the class norm. The sweep is class-correctness, not raising numbers until things pass. Sites were moved ONLY where the bash body demonstrably spawns something (git, node, npm, a CLI); self-contained shell snippets were left where they are, and are listed as deliberately unchanged: pure if/printf bodies (copilot-install), pure array/case builtins (code-review-pipeline-regression:638), a documented pure-shell gsd_run stub (host-integration), single-process hook calls (workflow-guard:222/271/302), and a deliberately tight 5000ms fast-check hook (gsd-write-guard.property). Nothing was lowered. process-seam.test.cjs:513 (literal 300) is untouched on purpose -- it tests timeout BEHAVIOR, so raising it would destroy what it asserts. Shared file-level constants were the trap here, and were handled per file rather than by redefinition: GIT_TIMEOUT_MS has ~15 users in git-base-branch and only 1 is a fan-out; WORKTREE_TIMEOUT_MS has 16 users in worktree.test.cjs and 3 are; PROBE_TIMEOUT_MS has several in three more files. In each the CALL SITE was changed and the constant left alone, so no single-plumbing-call site silently inherited a 60s bound. The one exception is hooks-opt-in.test.cjs, where HOOK_TIMEOUT_MS has exactly one consumer -- spawnHook, the fan-out itself -- so redefining it is identical in effect and reads better. Only two of these sites have actually been observed failing. The rest cite that shared class and those two run ids rather than inventing evidence of their own.

Behruz Nassre Esfahani	622f43353c	fix(#3299): tracer feedback gate honors workflow.human_verify_mode (#3390) ... * fix(#3299): tracer feedback gate honors workflow.human_verify_mode The tracer feedback gate (#2294) predates `workflow.human_verify_mode` (#3309, whose scope was the planner and verifier only), and branched on auto-mode alone. Under the documented `end-of-phase` default an interactive run therefore halted after EVERY `type="tracer"` task, synthesizing a `checkpoint:human-verify` no planner ever emitted and asking the user to retype a verdict the executor had just computed — at the cost of a full executor cold-start each time. Planner-side suppression cannot reach this halt because the executor synthesizes it at runtime, which is why #3309 did not close it. The gate now branches on HUMAN_VERIFY_MODE in the interactive path: under `end-of-phase` an automated-only tracer `<verify>` is re-run and, on success, expansion continues with no checkpoint. HALT-on-failure is unchanged. `mid-flight`, `gate="blocking-human"`, and tracers carrying genuine `<human-check>` evidence all still stop; the autonomous branch is untouched. `--default end-of-phase` on the config read is load-bearing, not decorative: `workflow.human_verify_mode` is absent from SCHEMA_DEFAULTS, so a bare `config-get` exits non-zero with `Key not found` on any project whose config.json predates #3309 — which is the reporter's exact config and every pre-existing project. Both copies of the rule (workflows/execute-plan.md and agents/gsd-executor.md) are updated together; the reference doc records the seam and the human-check-still-halts rationale so it cannot recur. Fixes #3299 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * chore(#3299): add changeset Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): reconcile the canonical schema table and the stale acceptance test Review round 1 (trek-e) — three items, all in the drift class this PR is about, two of them landed inside this PR's own diff. 1. docs/reference/plan-md.md:233 — CONTEXT.md names this file the canonical schema reference for the tracer task-type contract, and its Task-types row still claimed interactive runs unconditionally present a checkpoint:human-verify. CONTEXT.md and docs/AGENTS.md were updated in the first round; this one was missed, so the authoritative reference was the wrong answer. The row now carries the human_verify_mode-conditional behavior and points at the canonical precedence chain. 2. tests/tracer-bullet.test.cjs — the docs assertion only checked that a tracer ROW EXISTS, never its content, which is why CI could not see the drift. It now asserts the row's actual claims and rejects the pre-#3299 wording. Separately, the #1945 acceptance test named 'interactive run emits checkpoint:human-verify after the tracer' kept passing only because its substrings still occur in the fallback clause, while its name asserted the opposite of shipped behavior. Renamed and narrowed to what #1945 still guarantees, plus a new interactiveIsConditional pin so the unconditional prose cannot be restored under a passing substring check. 3. plan-md.md's <verify> row now documents that the legacy bare-text form (valid, and still shown at :179) does not reach the #3299 auto-continue — only a <verify> carrying <automated> does — so the benefit is silently unreachable for tracers using that format. Mutation-verified: reverting the plan-md row fails 1 test; reverting the executor's interactive branch fails 4. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): make the tracer gate reachable from the planner template, and bind the assertions Peer review round 3 found two Majors, both verified by reproducing the mutation before fixing. MAJOR 1 — the fix was largely inert on its own default path. agents/gsd-planner.md's Nyquist Rule (:191) says every <verify> includes <automated>, but the tracer-specific template twelve lines later emitted the legacy bare-text form. The gate auto-continues only on a <verify> carrying only <automated>, so every tracer produced from the canonical template fell to the STOP fallback and #3299's benefit was unreachable for exactly the task type it targets. Template now wraps in <automated>; a contract assertion pins it so the two cannot drift apart again. MAJOR 2 — the new assertions did not bind condition to action. Appending 'Nevertheless, interactive runs always present a checkpoint:human-verify' to the canonical row, and 'then immediately STOP and return a checkpoint:human-verify' to the auto-continue clause in BOTH operative copies, restored unconditional interactive checkpointing and left the suite 35/35 green. Every required keyword still matched. Fixed by: - clause 2 must now contain no STOP outcome and emit no checkpoint at all — 'never a checkpoint' has to be true OF the clause, not merely stated in it; - interactiveIsConditional replaced with the ordered-clause parse plus the same no-STOP property, instead of proving only that HUMAN_VERIFY_MODE appears somewhere on the line; - the plan-md.md Autonomy cell is now pinned EXACTLY rather than by keyword presence. Deliberately brittle: CONTEXT.md names that table the canonical schema reference, so a wording change must be a conscious edit in both places. Mutation-verified after the fix: the combined semantic regression now fails 3 tests; reverting the planner template fails 1. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): exact-pin the safety clauses instead of blacklisting outcome verbs Peer review round 4. Blacklisting did not hold, twice over: - Round 3 banned literal STOP and the 'return a'/'present a' checkpoint forms in the auto-continue clause. Round 4 defeated that by appending 'then pause and invoke checkpoint_protocol with a checkpoint:human-verify before expansion' — none of the banned tokens, same restored interruption after every successful tracer. 36/36 passed. - The planner guard looked for <automated> anywhere inside <verify>, so '<verify>[...]<!--<automated>--></verify>' satisfied it while leaving the legacy bare form operative. 107/107 passed across tracer, planner and the three size-cap suites. Synonyms are unbounded; the clauses are not. Both are now pinned exactly on normalized whitespace, the same approach already proven on the plan-md.md Autonomy cell, with defence-in-depth checks behind them: no checkpoint-emitting or blocking outcome in any wording inside clause 2, and the planner's <verify> body must be exactly one non-empty <automated> child with no commented markup. These pins are deliberately brittle. Each is a safety contract, so changing the behavior must be a conscious edit in both the prose and the expectation. Mutation-verified: the synonym-checkpoint mutation fails 1; the commented-out wrapper fails 1; the round-3 literal-STOP + contradictory-doc-row regression fails 3. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): strip comments, require uniqueness, pin whole regions Peer review round 5. Exact-pinning one clause was still bypassable two ways, both reproduced before fixing (each left the suite fully green): - COMMENTED DECOYS. Put the correct text in an HTML comment followed by a live wrong copy: every extractor selected the commented decoy. Worked against the planner template, the canonical plan-md.md row, and both executor branches. - SURROUNDING OVERRIDE. Insert 'after every tracer, pause and invoke checkpoint_protocol before expansion, regardless of the mode-specific rules below' immediately ABOVE the pinned clause, or 'ignore row 3; always wait for approval' below the canonical table. The pinned text was untouched, so equality held while the shipped meaning inverted. The shape that holds, applied to every operative surface: 1. strip HTML comments BEFORE selecting, so a decoy cannot be chosen; 2. require the structural anchor to occur EXACTLY ONCE, so a live second copy cannot hide behind a correct first one; 3. pin the ENTIRE decision region, not one clause, so no unparsed prefix or suffix can override what the pin proves. Applied to: the executor's whole tracer branch, execute-plan.md's whole dispatch line, checkpoints.md's whole precedence section, and plan-md.md's Autonomy cell. Also addresses the round-5 Minor: the planner template is now asserted STRUCTURALLY (exactly one <verify> in the fenced block, body exactly one non-empty <automated> child) rather than pinning the descriptive placeholder verbatim, so behavior-preserving wording changes no longer false-fail. The clause and section pins keep their exact form — those have a safety rationale the placeholder copy does not. Mutation-verified, all six rounds: override-above-clause 1; commented decoy row 1; commented decoy branch 1; ignore-row-3 override 1; synonym checkpoint 1; commented-out wrapper 2. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): drop the superseded exact-placeholder planner assertion Peer review round 6, Minor. The round-5 brittleness fix ADDED a structural planner assertion but left the old exact-placeholder one in place, so the over-brittleness it was meant to remove was still live: rewording the descriptive placeholder while preserving exactly one non-empty direct <automated> child failed the old test and passed the new one. Removed the old test. The structural assertion is the real contract — the gate auto-continues on the SHAPE of the verify, not on the wording of a placeholder. Verified both directions: a behavior-preserving reword now passes; reverting the template to bare <verify> still fails. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): select operative prose via parsePredicates, not a hand-rolled scanner Peer review round 7. I had judged the round-6 selector bypass adversarial-only and out of scope, intending to disclose it. Both premises were wrong, and the review said so: - 'Needs new src API' — false. parsePredicates is ALREADY a public export and internally uses the repo's interleaved fence/comment scanner. Instrumenting candidate lines as throwaway predicate declarations borrows that scanner with no src change at all. - 'Adversarial-only' — false, and this is the part that mattered. Two ORDINARY edits silently turned the guards into decoy checks: * a forgotten '-->' comments the live rule through to EOF, and the balanced-only stripper still saw and accepted the commented rule; * a normal fenced documentation example of the rule, plus a whitespace-only reformat of the live list item, made the selector choose the example. Neither needs intent. A dangling comment is a typo; a fenced example is good documentation. Together they reproduce exactly the accidental drift #3299 came from — with CI green. The selection layer now defers to parsePredicates for operativeness, uses whitespace-tolerant anchors so a reformat cannot decouple the live line from its pin, extracts regions by operative line index rather than string search, and carries a self-guard test proving fenced / balanced-commented / after-unclosed-comment copies are all excluded. The helper also ignores indexes it did not inject, so a pre-existing GSDTEST.CANDIDATE line cannot pollute it. Verified both ordinary-edit scenarios now fail the suite (each was green before). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): close the operative-selection gaps the maintainer blocked on trek-e's Blocker: the operative-line selection layer had three gaps, all reachable by ordinary future doc edits rather than sabotage. He independently found a fourth I had not disclosed. All are fixed. 1. INDENTATION PROMOTION (his find, not in my disclosure). The instrumentation replaced a matched candidate with an UNINDENTED marker regardless of the original line's indentation. A 4-space-indented CommonMark code block is not skipped by parsePredicates (it accepts indented declarations by design), so stripping the indent PROMOTED an indented decoy to operative — the exact inversion of the guard's purpose. The marker now preserves the original indent, and a candidate that is itself indented 4+ spaces is never injected. 2. NO SET MEMBERSHIP. The filter accepted any in-range integer, so a pre-existing literal GSDTEST.CANDIDATE=<valid index> in source text could pollute the count. Now filters on a Set of the indexes actually injected on this call. 3. RAW FENCE SELECTION (planner). The template test matched the first raw ```xml fence after the marker with no fence/comment awareness — the one selection in the suite that was not operative-aware — so a commented-out decoy template between the marker and the real one would be selected while the live template regressed. The opener must now be operative AND the first non-blank line after the marker. 4. RAW END ANCHOR (regionFrom). The end anchor was tested against raw lines, so a fenced example containing a ### / <type line truncated the pinned region early — a false FAILURE on a legitimate doc edit. End anchors now go through the same operative filter as start anchors. Mutation-verified: the indented-decoy + whitespace-varied-anchor combination and the commented-out fence decoy each now fail the suite (both passed clean before). Truncation is confirmed fixed by extraction — the region spans the full section and retains the content following a fenced example, where it previously stopped at it. Note on the remaining brittleness: adding a fenced example INSIDE a pinned region still fails the whole-region exact pin. That is the intended tradeoff for a safety contract, not the truncation defect, and is called out as such. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * test(#3299): allow-list operative indentation; pin marker provenance Review round 9. BLOCKER — the round-8 indentation guard was written as a DENY-list, /^(?: {4,}|\t)/, and CommonMark has more indented-code forms than that enumerates: " \t", " \t" and " \t" all open an indented code block and all slipped through, so an indented decoy was still promoted to operative while the live rule regressed (34/34 green). Inverted to an allow-list — only 0-3 literal spaces is ordinary block indentation; anything else is code. Enumerating the bad shapes was the error, not the specific regex. MINOR — the injected-index Set validated the marker's VALUE but not its SOURCE. A pre-existing literal `GSDTEST.CANDIDATE=<n>` could name an index that some other (skipped) candidate had contributed to the set, and be accepted. Now also requires p.line - 1 === Number(p.value): the predicate must have been parsed from the line it names. MINOR (false negative) — ```xml title=x is a valid CommonMark info string, and requiring exactly ```xml failed the suite (33/34) on a behavior-preserving edit. Both the opener assertion and the extraction now accept an info string. Mutation-verified: the mixed " \t" decoy and the forged-provenance marker each now fail; the info-string fence no longer false-fails. KNOWN LIMITATION, disclosed on the PR rather than papered over: parsePredicates is a predicate parser, not a general CommonMark operativeness oracle. Two standards-valid constructs still read as operative — a lazy blockquote continuation line (state opens only on a line that literally starts with ">"), and a comment opened mid-line ("prose <!--", where state opens only when the trimmed line STARTS with "<!--"). Closing those means either teaching the shared src/context-predicates.cts about container/lazy-continuation state — a change to a module every health rule consumes, well outside a tracer-gate fix — or hand-rolling a CommonMark parser inside a test, which is how this suite got into trouble in the first place. Left for the maintainer to scope. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * chore(#3299): re-arm the execute-plan.md emitted-drift ack after the base merge The #3299 ack rode on tests/emitted-drift-acks/2652-quick-diagnose-dispatch-isolation.json, which upstream retired in 362d0434b (#3370) once #2728's entries were spent. #3370's own fragment now owns execute-plan.md at the base, so a new 3299-*.json naming that path would collide — mergeAckSources rejects a duplicate key across fragments rather than silently last-winning. Re-arms #3370's entry instead, the mechanism the gate is built for (a spent ack whose reason changes in the diff is live again), carrying #3370's own reason forward verbatim so the base growth keeps its account. Verified: emitted-attribution 175/175 against origin/next@be9329b10. * fix(#3299): honor golden rule 6 in the tracer gate, extract the chain Addresses the review on #3390 (B1-B3, M1-M4, minors). B3 — checkpoints.md asserted two incompatible rules about the same gate. Golden rule 6 says gate="blocking-human" stops for a human in every mode; the precedence table scoped row 1 to interactive runs, so a first-match chain let an auto-mode tracer carrying that gate fall to row 2 and auto-continue. Rule 6 wins: row 1 is now "Any run, any mode", the justification sentence it falsified is gone, and the STOP is evaluated before the auto-mode branch at all three dispatch sites — gsd-executor.md, execute-plan.md and the plan-md.md schema row. Unreachable by our planner is not unreachable: src/verify.cts parses only `type` and never consults `gate` on non-checkpoint tasks, so an imported PLAN.md can carry it. B1 — the LARGE-tier cap. gsd-executor.md is 49150 on next against a 49152 cap, so this PR could not add a byte. Extracted rather than trimmed: the precedence chain now lives only in checkpoints.md (already @-imported by <checkpoint_protocol>, so no new load), and the duplicate summary inside that protocol section is a pointer. The rationale the earlier trim deleted is restored — "production-quality, never a throwaway" and "Pouring more layers onto a broken foundation...". Result 49097: 55 bytes under the cap and a net 53-byte REDUCTION against next, so the PR returns headroom instead of consuming it. B2 — merged upstream/next and resolved all three drift-ack conflicts. 2775 changed shape upstream (string -> {reason}); adopted the new form. M1 — the 2775 ack claimed the Nyquist Rule sat "twelve lines earlier"; it is ~75 lines. Corrected to "earlier in the file". M2 — ack arithmetic restated from measurement, not from a stale base. The 2943 #3299 append is DELETED: with gsd-executor.md now shrinking there is no ripple to acknowledge, and emitted-attribution correctly flagged the entry as stale. M3 — changeset rewritten to the documented bold-lead + em-dash one-liner. M4 — the two self-defeated shapes are gone. The planner-human-verify-mode presence checks now go through operativeLineIndexes. The config-get check does NOT: all three reads live inside ```bash fences, which is their correct executable form, and that selector excludes fenced lines by design. It instead pins exactly one live, uncommented, fenced read per file — mutation-tested against both a commented-out read and a duplicate. Minors — dangling colon lead-in dropped, a "below" pointer that pointed above corrected, and the `(default)` asymmetry between the two dispatch copies aligned. Two defects the merge surfaced, both caught only by the full suite: the new #3576 gate rejected this PR's own bare `references/checkpoints.md` cite in planner-human-verify-mode.md (rewritten to the canonical gsd-core/ form), and the line-keyed PROSE_ALLOWLIST entry for gsd-executor.md needed 794 -> 795 after this change shifted the line. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): correct the size record the 08-22 merge falsified Review round: one Major, four Minors. Major — the #3299 arm's arithmetic was measured before the merge and is now wrong in a document whose whole purpose is to be an accurate size record. Re-measured at head: execute-plan.md is 39315 B on next and 40111 B here, so the 796-byte delta was right but the endpoints and the headroom were not (849 bytes against DEFAULT_CAP 40960, not 1003). The superseded figures are named rather than silently replaced. Confirmed the workflow cap counts LF BYTES while the agent cap counts CHARACTERS — two caps in two units, one per file. Minor 1 — 2943-context7-tool-name.json reverted to next. JSON.parse of both sides was already identical; the diff was an em-dash/times-sign re-serialization left over from adding and then removing the #3299 arm. No business in this PR. Minor 2 — the duplicated `tracer row Autonomy cell` test is gone. Both copies were new here and carried the same ~8-line canonical string; the one removed selected its row with a raw startsWith find, the shape this suite records at :477 as defeated in round 1. Its rationale — why the cell is pinned EXACTLY, and the append-a-contradiction attack that defeated keyword matching — is carried onto the surviving fence-aware copy rather than deleted with it. Minor 3 — the executor's condensed interactive clause said only "re-run, continue", which does not distinguish pass from fail; read in isolation it invites expansion onto a broken slice, the outcome the gate exists to prevent. Now "re-run; fails → HALT as above, passes → continue, no checkpoint". The pinned expected string moved with it. Executor at 48,905 chars, 247 under the cap. Minor 4 — 2775 asserted two different current sizes for gsd-planner.md. The stale half is next's own text taken wholesale, so the contradiction was inherited; it now reads as a before-figure rather than a current one. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): cite the plan-md example by section, not by a drifting line Review round 7, Nit N-1. The 2775 ack fragment justified its one-line formatting with "matching docs/reference/plan-md.md:207's own example style". At head, :207 is prose; the one-line <verify><automated> example it means is at :222. The citation was accurate when written (77c2fda, f23205c) and drifted with a later merge of next. Re-pointed by section rather than by line — it has already drifted once, and the fragment's whole purpose is to be an accurate record — and the drift itself is recorded inline so the correction does not quietly overwrite what the earlier number said. Also narrows the changeset's "any task with gate=blocking-human" to "any tracer carrying gate=blocking-human" (found by Codex in the whole-PR pass). Golden rule 6 and the #3299 decision table both scope that gate to checkpoints and to the tracer feedback gate; the normal type="auto" branch never inspects `gate`, so the wider claim promised behavior the implementation does not have. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): answer fence-delimiter liveness by insertion, not replacement Review round 9. The round-8 fence-awareness fix was itself unsound, in the same class it was added to close. `operativeLineIndexes` detects operative lines by REPLACING each candidate with a throwaway predicate declaration and asking `parsePredicates` which survived. Sound for ordinary content lines. Not sound for a fence DELIMITER, which is exactly what the tracer-template selection passed it: deleting every ```xml OPENER leaves each matching closer to become an opener, and since `computeSkippedLineFlags` is a strict FORWARD state machine, fence parity inverts for the whole remainder of the document. Measured against the real file rather than argued: agents/gsd-planner.md has 3 live top-level ```xml openers — 0-based 180, 232, 262. operativeLineIndexes reported 180 and 262. Line 232, the "Task-level TDD" example, read NON-OPERATIVE — a wrong answer from a helper whose only job is that question. It passed only by parity coincidence, and one extra live example anywhere earlier flipped it to a false FAILURE blaming a decoy that does not exist: HEAD as-is | anchor 260 | openIdx 262 | ASSERTION PASSES +1 unrelated ```xml example | anchor 265 | openIdx 267 | ASSERTION *** FAILS *** Fixed by asking the question a way that perturbs nothing. `isOperativePosition` INSERTS a marker on its own line immediately before the candidate instead of replacing it. Insertion preserves every delimiter, and because the skip-state machine runs strictly forward, a line inserted at `idx` observes exactly the fence/comment state the candidate observes, with nothing but the marker between them — so marker-operative IS the candidate's position-liveness. The review's suggested direction (substitute a same-shaped opener that still opens a fence) cannot work here: the marker would then be inside the fence and would never parse as a predicate at all. Position-liveness is not content-liveness, so the helper also rejects a line that is entirely comment (`<!-- ```xml -->`), rather than leaving that to each caller's own shape test to happen to exclude. `operativeLineIndexes` now THROWS when its candidate regex matches a fence delimiter, so the unsound route cannot be reached again by a future caller rather than only being fixed at the one site that got it wrong. Verified with the same extra-example scenario above: with the fix, all 35 rows stay green. Teeth: reverting the call site to `operativeLineSet` turns the tracer-template row red on the new guard. The regression row pins both live openers (the second is the one the deletion route lost), the block-commented and same-line-commented openers, a line inside a fence, and re-checks both openers after unrelated lines shift above them. Only tests/tracer-bullet.test.cjs changes — no agent file is touched, so the 5-char gsd-planner.md and 19-byte gsd-executor.md headroom are unaffected. Verified: `npm run lint:ci` exit 0; full `npm test` 31307 tests / 31292 pass / 0 fail / 14 skipped, TMPDIR unset, against a freshly synced origin/next. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3299): guard the delimiter class, match the scanner, pin the assignment Codex full-PR review of #3390, run against the round-9 head. Three defects, two of them in the code that round added. 1. The mode-read pin survived the regression it exists to catch. `READ` matched the config-get substring only, so rewriting the shipped line as `IGNORED_MODE=$(gsd_run query config-get ...)` kept the row green while nothing defined HUMAN_VERIFY_MODE — the gate falls through to STOP and #3299 is back with the suite passing. The regex now requires the assignment. A lookahead after `end-of-phase` closes the other half: the bare prefix also accepted `--default end-of-phase-wrong`. Proven by mutation: renaming the variable in agents/gsd-executor.md now turns that row red, and did not before. 2. The round-9 fence-delimiter guard was a SAMPLE of the class, not the class. It probed a fixed list of five delimiter strings. `~~~xml`, ```json, `~~~~` and arbitrary info strings all walk past any list short enough to write down — the guard was added precisely because one such regex had already slipped through. Now matched against the lines the regex actually selects in the document, which cannot go stale and cannot miss a spelling nobody thought of. Four such spellings pinned as rows. 3. `isOperativePosition` disagreed with the scanner it delegates to. For `<!-- closed --> real content` it stripped the span, found surviving content, and answered "live". `computeSkippedLineFlags` skips an ENTIRE line whose trimmed text starts with `<!--`, balanced or not, before it considers fences at all. Verified directly against parsePredicates. It now applies the scanner's own rule instead of out-reasoning it. Latent for the present caller (its anchored ```xml shape cannot match a comment-prefixed line), real in general. Disclosed rather than fixed, and raised with the maintainer: the exact executor region pin ends before the second operative tracer-gate paragraph at agents/gsd-executor.md:327, which is only heading-checked — so contradictory later instructions could ship. How much of that file to pin is a call for its owner. Independently probed isOperativePosition across 19 edge cases before the review (line 0, CRLF, tab / 4-space / mixed " \t" indentation, 0-3 space fences, nested fences, ~~~ fences, info strings, bounds); all correct. That probe is what surfaced finding 2, which the review then confirmed from the other direction. Verified: `npm run lint:ci` exit 0; full `npm test` 31296 tests / 31281 pass / 0 fail / 14 skipped, TMPDIR unset. One caveat stated rather than smoothed over: in that run tests/planning-snapshot.test.cjs was truncated by concurrency after row A5 — 11 tests did not execute, which a 0-fail aggregate cannot show. Re-run in isolation it is 87 tests / 87 pass / 0 fail, and it is untouched by this change.

Behruz Nassre Esfahani	a44d513566	fix(#3712): confine in-process installs to a sandboxed HOME (#3725) ... * fix(#3712): confine in-process installs to a sandboxed HOME A runtime kind may declare a global `home` override resolved from os.homedir() rather than from the caller's configDir — codex's skills kind (`home: ".agents"`, ADR-1239 / #2088) is the only live case. Sandboxing configDir/targetDir does not contain it, and assertDestWithinConfigHome cannot see the class: that gate confines a destSubpath to whatever root it is handed, and here the root IS the escaped home. So an in-process caller that forgot to sandbox HOME wrote to, and pruned gsd-* entries from, the developer's REAL ~/.agents/skills. tests/agent-descriptor-parity.install.test.cjs's K1 loop did exactly that: it iterates every agents-kind runtime (codex included) with a sandboxed targetDir and an un-sandboxed HOME. Reproduced against a canary home on next @ adb46cdd8 — 71 gsd-* skill dirs deleted, a foreign `cloudflare` skill surviving, suite still exit 0. It is silent because the runtime's own config home is untouched, so the manifest keeps reporting a healthy install. FIVE writers resolve a kind `home` and then destroy under it. Three are reachable today — installRuntimeArtifacts, uninstallRuntimeArtifacts (install-engine.cts) and applySurface (surface.cts). Two are descriptor-dependent and guarded against a future descriptor change rather than a present escape: installOpencodeFamilySkills (behind the combined-family early return) and installAgentsKindStandalone. Those two are scoped to the single kind each destroys — passing the whole layout made codex's unrelated skills override trip a writer that never touches it. - src/test-home-guard.cts: refuse when a run under a test runner cannot be shown to have sandboxed HOME. NODE_TEST_CONTEXT (set by `node --test`) gates it, so installs outside a Node test context are untouched; GSD_TEST_MODE is unusable, as several candidate files including the offender never set it. Homes are compared by FILESYSTEM IDENTITY (st_dev + st_ino), not by pathname: path.resolve() resolves neither symlinks nor case, and realpath returns a canonical pathname that two routes to one directory can still disagree on (bind mounts). Verified on macOS/APFS — HOME=/users/<name> made the strings differ while naming the same directory, and the lexical form ALLOWED a write into the physical real home. FAILS CLOSED: a pair is "different" only when both identify, or one is definitively absent (ENOENT/ENOTDIR) while the other identifies; every other errno is "cannot tell" and refuses. Only when neither home identifies is a marker consulted, and it carries the sandbox PATH and must equal the home in effect — a boolean checked first let an ambient or stale value disarm the guard. - helpers: promote sandboxHome() out of its two byte-identical private copies, which is also what makes them record the sandbox; the three withFakeHome() helpers record it too. The marker NAME is duplicated as a bare string rather than required from the compiled guard, keeping helpers.cjs's documented no-built-lib-at-import-time contract; a test pins the two together. - agent-descriptor-parity: sandbox HOME across the K1 loop. - helpers-process-isolation: #3156's canary asserts on <home>/.gsd only, and its `--cursor --local` spawn cannot reach `.agents` at all, so an assertion added there would pass with all confinement removed. Add a discriminating row — a `--codex --global` spawn against a seeded ambient home — which also asserts the runtime still declares the override. Its check is a sampled inventory (dir names + each SKILL.md), not a tree compare. - install-write-confinement: predicate rows through the deps seam, covering the symlinked HOME, ambient and stale markers, and each sameDirectory branch (both-identify, one-absent, neither-identifiable), plus wiring rows that drive the REAL entrypoints so deleting a guard call site is red. Verified: guard fires end-to-end against a real un-sandboxed HOME (exit 1, zero deletions); the case-variant fail-open reproduced on APFS before the fix and refuses after; K1 file 29/29 green with skills intact; mutation-tested — each of the three reachable call sites, lexical-only comparison, and treating an unknown errno as "absent" each take exactly one row red, with every mutation echoed back; the process-isolation row negative-controlled by reverting installerEnv to its pre-#3156 leak (16/0 -> 13/3); a full npm test leaves ~/.agents/skills at 71. Stated residual: the two descriptor-dependent writers have no wiring test, because no runtime declares a `home` override on those kinds and neither can be exercised without inventing a descriptor. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3712): add changeset Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3712): let a sandbox nested inside the real home through the guard All six Windows shards of #3725 failed on legitimately sandboxed destinations. On Windows os.tmpdir() is %LOCALAPPDATA%\Temp — inside the user's home — so every sandbox a test creates is a descendant of the real home, and "does this land inside the real home?" answers yes for the safe case and the dangerous one alike. POSIX conceals this: /tmp and /var/folders both sit outside $HOME. Add the missing conjunct: a destination inside the real home is allowed only when it also sits beneath a HOME that was sandboxed away from the passwd home. Both halves are required — dropping the first re-admits a plain un-sandboxed install, and dropping the second decays into the "is HOME sandboxed?" check the module rejects, which a layout resolved before the sandbox walks straight through. Each is mutation-proven by a row that goes red without it. Also covers the two fail-closed branches of the new exemption, which survived mutation to `true` with the suite green, and avoids `<user>` in a docblock — the prompt-injection scanner reads it as a delimiter tag. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): close three writer/rollback gaps found reviewing the whole PR Cross-AI review of the full PR (not just the round's delta) surfaced three ways the guard could still be defeated: - The nested-sandbox exemption trusted the SPELLING of a destination. With HOME sandboxed to a directory inside the real home — legitimate on Windows — an aliased `.agents` (symlink, junction, subordinate bind mount) beneath it redirected an allowed path into the real home. Decide containment on the path the write RESOLVES to: walk up to the nearest existing ancestor, canonicalize, re-append the tail. - `migrateLegacyDevPreferencesToSkill` is a SIXTH writer that resolves a skills-kind `home` override. It creates rather than prunes, which is why it was missed, and `_runLegacyInstallMigrations` runs it before `installRuntimeArtifacts`' own assertion. Guarded, scoped to that kind. - Worst of the three: `bin/install.js` snapshots the resolved skills root before installing, and its outer catch rolls back by deleting and recreating every snapshotted `gsd-*` directory there. The guard's own throw landed in that catch, so refusing an un-sandboxed codex install provoked exactly the mutation the guard exists to prevent. Refusals are now marked and rethrown without rollback — nothing was written, so there is no partial install to undo. Every other error still rolls back. Also carries the sandbox marker into `installSpawnEnv`, so spawned installers are not refused on passwd-less CI images, and corrects three claims that no longer hold: "every writer" (six, and named), the unconditional "fails CLOSED" (the passwd-less marker branch is a deliberate weakening, and TOCTOU is out of scope), and the assertion that Windows os.tmpdir() is always %LOCALAPPDATA%\Temp (Node honors TEMP/TMP). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(#3712): name the guard's two limits instead of overclaiming Round-2 review found the prose had drifted ahead of the code. Corrected, with no behavior change: - The module still said FIVE writers; there are six, and the sixth is now named along with why it was missed (it creates rather than prunes) and why it carries its own assertion (it runs before the main one). - The canonicalization docblock listed subordinate bind mounts among the aliases it closes. It does not close them: a bind mount is not a link, so realpath keeps the mount-point spelling. `sameDirectory` already recorded that limit; the new helper now inherits it explicitly rather than contradicting it. Closing it needs mount-table introspection. - "FAILS CLOSED" was unqualified while the passwd-less marker branch is a deliberate weakening — with no passwd entry, nothing can contradict a marker naming the real home. - "Refuses BEFORE any write" was too broad: legacy install migrations run ahead of the layout-driven ones, which is exactly why the two rollbackInstallerMigrations() calls still execute before the rethrow. Only the codex skills-root rollback is skipped, and that is the only _codexPreConfigRollback() call site — applySurface is never called from bin/install.js and uninstall cannot reach it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): sandbox HOME in the opencode-family home-override parity rows The last two Windows failures, and the same platform asymmetry in a different disguise. This row drives a skills-kind `home` override on purpose — precisely what the guard polices — but relied on the override temp dir happening to sit outside the real home. It does on POSIX (/tmp, /var/folders); on Windows os.tmpdir() is under %USERPROFILE%, so the guard correctly refused and only Windows went red. Declare the sandbox instead of depending on the platform: HOME becomes the override itself, which is the home the call writes under. This is the fix the guard's own message prescribes, applied to the test rather than to the guard. Both failing Windows shards fail on exactly these two rows and nothing else; every other shard is green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): make sameDirectory answer NO when it cannot tell Review Major 1. sameDirectory()'s only caller is the passwd-less marker branch, which reads a `true` as permission to PROCEED: if (marker && sameDirectory(marker, osMod.homedir())) return; The fallthrough returned `true` whenever neither side identified — two absent paths, or two stats failing EACCES/EPERM/EIO on a locked-down host — on the reasoning that "cannot tell" should make the caller refuse. That reasoning was inverted with respect to this caller: it turned the passwd-less escape hatch into an unconditional bypass for any marker value at all, on precisely the hosts the fallback exists to serve. Only two things now answer yes: one resolved pathname, or two readable identities that match. Restoring the old fallthrough takes the new row red. Also from review: - Major 2 asked whether st_dev/st_ino discriminate directories on Windows, where Node derives them from BY_HANDLE_FILE_INFORMATION. The whole guard rests on that primitive, so assert it rather than argue it: a row comparing two distinct temp directories, and one directory reached by two spellings. It runs on every platform in the matrix, so Windows answers the question itself. - Minor 1: the refusal now names the real home it compared against, not just the destination it refused. That is the one fact needed to tell a true positive from a false one, and its absence is what made the Windows case a CI-log dig rather than a glance. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): refuse a HOME that merely spells the real home more widely Review round: one Blocker, four Minors, a Nit. N2 (the one with teeth) — a destination's ancestor chain is linear, so "inside the real home AND inside the effective HOME" admits two arrangements, not one. The intended `effectiveHome ⊂ realHome` is the Windows temp shape; `realHome ⊂ effectiveHome` — HOME at /Users, /home, C:\Users — is not a sandbox at all, it is the real home reached by a wider spelling, and it was exempting a stale destination pointing straight at ~/.agents. Third conjunct added; the docblock no longer claims two conditions suffice. Removing the conjunct reds the new row and nothing else. N4 — the migration guard resolved its OWN layout, and without capabilityRegistry, so a registry-dependent descriptor could make it vouch for a path the migration does not write: a guard reporting safe while the unsafe write proceeds. It now guards the destination already resolved by _resolveDevPreferencesSkillTarget, keyed on `installRoot !== targetDir` — which is exactly the condition under which a `home` override was declared, read off that same result. N1 — CONTEXT.md gains the Test Home Guard Module glossary entry that contributor-standards.md requires of a new Module. Not CI-enforced, so green CI was never evidence it was met. N3 — the docs/INVENTORY.md row was misfiled between install-fs-adapter and install-model-override-resolver; the table is alphabetical and the manifest already had it right. Moved, and its text now names six writers and the third conjunct. N5 — applySurface's signature docblock was two parameters stale; this PR added the second of them. N6 — the duplicated rollbackInstallerMigrations() adjacent to the new rethrow: two identical consecutive calls, not two phases. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): guard the sixth writer, and close two false-ALLOW paths Review round 3 (NEW-1, NEW-2) plus three defects Codex found in the whole-PR pass, each reproduced before it was fixed. NEW-1 — migrateLegacyDevPreferencesToSkill called the guard with no `deps`, so it bound real os/process.env and could not be wiring-tested the way the other three reachable writers were. It now takes the same optional `deps: { os?, env? }` tail parameter. The wiring block gains the missing fourth row, and a fifth pinning the ALLOW half; the test file's header docblock said "FIVE writers ... the three reachable today", contradicting the six/four statement this PR already put in src/test-home-guard.cts, CONTEXT.md, docs/INVENTORY.md and the changeset. Both directions of the guard's condition now fail a row when broken — previously neither did. NEW-2 — derivesFromSandboxedHome's docblock claimed "THREE conditions are required, and no two of them suffice". False for {2,3}: isInside is reflexive, so whenever conjunct 1 fires conjunct 2 already returns false on its own. Reworded as a fast path, which is what it is. Codex 1 (false ALLOW) — on a host with no readable passwd entry the marker branch returned as soon as the marker matched the effective HOME. That attests a caller sandboxed HOME and says nothing about where an already-resolved destination points, so a layout captured before sandboxHome() — still naming the real ~/.agents — was waved straight through: the same stale-layout shape the primary branch refuses by design. The marker must now identify AND contain every destination. Codex 2 (false ALLOW) — `installRoot !== targetDir` was the stand-in for "the skills kind declared a home override". The two are not equivalent: the inequality is false when the override resolves onto targetDir itself, which is exactly a configDir of $HOME/.agents. The guard was skipped and SKILL.md written into the real home under a test runner. _resolveDevPreferencesSkillTarget now reports hasHomeOverride off the same resolution instead of inferring it from two paths. Codex 3 (prose) — the shared refusal message claimed every guarded writer prunes; the migrate writer only creates. The changeset headline claimed in-process installer calls can no longer reach the real home, which is wider than the guard: writeNonClaudeDefaults still writes ~/.gsd/defaults.json through os.homedir(). INVENTORY's and CONTEXT's fail-closed sentences omitted sameDirectory's pathname-equality shortcut. All four narrowed to what the code does. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): let the sandbox marker follow an overridden HOME Found by Codex in the whole-PR pass. installSpawnEnv spreads `overrides` last so an explicit HOME wins — deliberate, and its docblock tells callers needing per-spawn isolation to pass their own { HOME, USERPROFILE }. But the #3712 marker was set before that spread, so such a caller got HOME=<theirs> and marker=<helper default>. On a host with no readable passwd entry the guard compares the two and refuses a legitimately sandboxed spawn — tests/install.test.cjs:7143 and install-shared.cjs's own runInstaller both take that path. The marker is now derived from the final HOME unless the caller supplied one explicitly. The contract test asserted HOME after an override but not the marker, which is why it stayed green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * docs(#3712): name the shipped guard condition, not the deleted one Review round 4 of #3725. Two artifacts this PR adds still described `target.installRoot !== targetDir` in the PRESENT tense as the live guard condition on `migrateLegacyDevPreferencesToSkill`. The shipped condition is `runtime && target.hasHomeOverride` (src/install-engine.cts:510). This is not ordinary doc drift. The named condition is the exact false-ALLOW the previous round closed: a `home` override resolving onto `targetDir` — a configDir of `$HOME/.agents`, which is where codex's override points — makes the inequality FALSE while the override is declared, so the guard was skipped. A maintainer reading CONTEXT.md:290 as authoritative would believe the guard still skips that case. - tests/install-write-confinement.test.cjs — the ALLOW-half row's comment. Its "teeth" rationale is unchanged and still correct as written. - CONTEXT.md:290 — the Test Home Guard Module glossary entry, a documented PR gate. Now states the condition and names the inequality only as what it is NOT, with the reason. The three surviving mentions of the inequality are all past-tense or negated (src/install-engine.cts:448, :508 and the sibling test comment at :3698) and are correct as they stand. Verified: `npm run lint:ci` exit 0; full `npm test` 31327 tests / 31312 pass / 0 fail / 14 skipped, run with TMPDIR unset. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(#3712): canonicalization fails closed, matching identify's errno split Codex full-PR review of #3725, run against the round-4 head. `resolveThroughLinks` caught EVERY realpathSync error and fell back to `path.resolve(dest)` — the lexical spelling. That inverts the function's own purpose. An aliased `<sandbox>/.agents` that cannot be canonicalized keeps its sandbox spelling, satisfies the nested-sandbox exemption at :227, and the write is ALLOWED into the real home — the exact escape this walk exists to close. The module documents that it fails CLOSED with ONE named exception (the marker branch); this was a second, unnamed one. Split by errno, and deliberately by the SAME split `identify` already draws rather than a second policy in one module — both answer "does this path exist as named?", so they must not disagree: ENOENT / ENOTDIR -> walk up. The ordinary case: a fresh install resolves a destination nothing has created yet, so realpath fails on the leaf and on every not-yet-created ancestor. Refusing here rejects every install. anything else (EACCES, EPERM, ELOOP, EIO) -> refuse. The component exists but cannot be resolved, so the guard cannot tell where the write lands. Three rows in the predicate block, beside the other aliasing rows: - a symlink CYCLE in the destination path (ELOOP) -> REFUSE - a destination that does not exist yet (ENOENT) -> ALLOW - a component behind a regular file (ENOTDIR) -> ALLOW Teeth checked against the artifact the test loads, not the source: reverting the condition to the swallow-everything shape in the compiled test-home-guard.cjs turns row 1 — and only row 1 — red. The ENOTDIR row caught a stale build during development, which is the point of asserting on the compiled file. CONTEXT.md and the resolveThroughLinks docblock both record the new behaviour, so this does not repeat the prose-vs-code drift the round-4 finding was about. The changeset's existing scope sentence now bounds "six writers" to the `installRuntimeArtifacts` call tree and names `cmdGenerateDevPreferences` — which resolves the same codex `home` override through `getGlobalSkillsBase` and writes SKILL.md beneath it unguarded. It has no in-process caller today (its only direct require-and-call is a spawnSync with HOME sandboxed), so it is latent rather than live, and whether it belongs in this PR is raised with the maintainer rather than decided here. Verified: `npm run lint:ci` exit 0; full `npm test` 31330 tests / 31315 pass / 0 fail / 14 skipped, TMPDIR unset.

Tom Boucher	004e9dd741	fix(#3007): resolve Codex reasoning effort per model and make every clamp visible (#3765) ... * test(#3007): failing-first suite for per-model Codex effort capability RED by construction. Binds to behavior renderEffortForRuntime does not yet have: an optional third `model` argument, a per-model advertised-level table, `max` passing through instead of clamping to `xhigh`, `minimal` clamping to `low`, `ultra` rejected outright, and clamp visibility (`requested`/`clamped`/ `reason`) so a downgrade is legible from resolver output rather than silent. Two of these pin defects that exist on next today: - `max` is discarded. Both Codex models whose catalog entries are retrievable (sol, luna) advertise `max`; GSD clamps it to `xhigh` and reports nothing. - `minimal` is emitted to a model that refuses it. providerPresets.openai. haiku.low pairs gpt-5.6-luna with reasoning_effort "minimal", and luna's advertised floor is `low`. GSD is sending a value into a document Codex itself validates. The parity test is what pins that fixed, and it names the offending path/model/effort when it trips. Also corrects tests/model-resolver.test.cjs:351, which asserted renderEffortForRuntime('codex','max').value === 'xhigh' -- the defect pinned as though it were a contract. ADR-443 recorded "Codex has no max" as fact and it was true when written; Codex has since added both `max` and `ultra`. That is a stale premise, so the assertion is corrected here rather than worked around. The property test asserts the invariant the whole change exists for: a rendered effort is always a level the target model actually advertises, or an explicit rejection. There is no third outcome. * fix(#3007): resolve Codex effort per model, and make every clamp visible Codex declares supported_reasoning_levels per MODEL and validates against it, so a single per-runtime capability set cannot be right for all of them. GSD's was wrong in both directions at once. `max` reaches Codex now. ADR-443 recorded "Codex has no max" as fact and clamped max -> xhigh on that basis; it was accurate when written, and Codex has since added both `max` and `ultra`. Every Codex model whose catalog entry is retrievable advertises `max`, so the clamp was discarding a level the provider supports, silently, on the most-used path. `minimal` stops reaching Codex. No Codex model advertises it -- both retrievable entries floor at `low` -- yet providerPresets.openai.haiku.low paired gpt-5.6-luna with reasoning_effort "minimal". GSD was writing a value the receiver validates and refuses into a file the receiver reads. Being unconservative in what you send is the half of Postel's rule with no defensible reading, so that preset is corrected and a parity test pins it. `ultra` is refused rather than laddered. Codex's own catalog calls it "Maximum reasoning with automatic task delegation": at ultra, effective_multi_agent_mode returns Proactive and Codex spawns sub-agents on its own initiative, underneath GSD's orchestration rather than inside it (#2167). It is a mode switch, not a reasoning depth, so it is not added to the universal ladder -- which stays provider-agnostic by ADR-443's design -- and it is rejected even for gpt-5.6-sol, which does advertise it. Clamping it down to `max` was considered and rejected: that silently discards what the user actually asked for. Clamping is now visible. RenderedEffort carries requested/clamped/reason and resolve-execution surfaces them. The previous table clamped correctly but invisibly, so a user asking for `max` on Codex had no way to find out they were getting `xhigh` -- exactly the failure mode the robustness principle's modern critique warns about, and why "be liberal" has to mean "liberal and loud". Also closes a latent trap found while reviewing the implementation: the clamp-up loop walks the ladder upward, and for a future model advertising `ultra` but not `max` it would have selected `ultra` as the clamp target -- re-entering by the back door the mode the rejection above exists to keep out. A clamp may never produce a value that a direct request for that value would refuse. Unreachable with today's catalog, which is why no test caught it; a test now asserts the invariant directly. Signature stability is preserved: the third `model` argument is optional and the two-argument form still resolves, against the family baseline. That form's BEHAVIOR does change for `max` and `minimal`, and it must -- keeping the old answer would have fixed the defect only where a model happened to be threaded through and left it live everywhere else. tests/model-resolver.test.cjs:351 asserted the defect as if it were a contract and is corrected here rather than worked around. * fix(#3007): close every review finding on the Codex effort alignment Two isolated reviewers, correctness and security. Both found the same two blockers, and the per-model work was inert on every surface that matters until this commit. BLOCKER — resolve-execution never passed the model and discarded the clamp. cmdResolveExecution called the two-argument form and emitted only effort_rendered/effort_param/effort_propagation, so the per-model table was unreachable from production code (tests were its only caller) and requested/ clamped/reason were computed and thrown away. Requested outcome 3 names "the effective rendered effort in resolver output" specifically, so the feature was unmet on the exact surface the issue asks for. Now passes the resolved model and emits effort_requested / effort_clamped / effort_clamp_reason, flat, matching the existing key convention rather than introducing a nested object. BLOCKER — the docs described output that did not exist. CONFIGURATION.md showed a nested {"effort": ...} sample; the real result is flat and those keys were absent entirely. A reference doc asserting a JSON path a reader can copy is worse than no doc. Corrected against the actual emitted key set. MAJOR — the argv channel still shipped both original defects. EFFORT_ARGV.codex kept minimal in its supported set and still clamped max down to xhigh, so the invocation-time and install-time channels disagreed about the same runtime's capability: --host codex with max emitted xhigh while the generated TOML said max. This is the repo's documented generative-fix-divergence class, so both tables now cross-reference each other and a parity test fails if they ever diverge again. MAJOR — malformed catalog data failed OPEN and could crash the CLI. A null _baseline became an EMPTY Set that is nonetheless truthy, so the nullish fallback never fired and every effort rendered as null. And a non-array value made the Set constructor throw at module load — model-catalog.cjs is required across the whole CLI, so one bad JSON value killed every command, not just codex effort. Guarded on size and filtered to array values; both degrade to the hardcoded baseline. MAJOR — value widened to a nullable string with two consumers left behind. runtime-artifact-conversion passed it straight into injectEffortFrontmatter (a null effort key in generated frontmatter); install-effort-resolver still declared a non-nullable return, a structural lie that silently defeated null checking. Both corrected, both omitting the key on null — the same posture as 'inherit', where omission means "follow the host default". MAJOR — the per-model table is inert today, and the docs now say so. All three shipped models advertise the same usable range and ultra (sol's only differentiator) is rejected for every model, so no observable output differs by model. The table stays because Codex declares capability per model and the sets are free to diverge — a single per-runtime assumption is precisely what went stale and produced this issue — but overselling it as a visible per-model feature would have been the same class of error as the doc blocker above. Tests: three passed under a full revert and are strengthened rather than deleted, since each guards a real contract (#3533's inherit rule, the undeclared-host rule, off-ladder handling) — they now also assert the clamp-visibility fields, which only exist after this change. The fast-check property is kept for its shrinking, and a deterministic nested loop over the full cross-product now sits beside it so coverage is exhaustive rather than sampled. Also folded in earlier: bin/install.js generated the Codex TOML with the two-arg form and would have written a literal null reasoning effort on the ultra path; CONTEXT.md's Model Catalog Module glossary entry now records CODEX_MODEL_EFFORT. The installer defect was found by the co-change gate, not by a reviewer — install.js is a historical co-change partner of model-catalog.cts that this diff had not touched. * test(#3007): correct assertions that pinned Codex's stale effort premise Thirteen pre-existing tests encoded "Codex has no max" as fact and failed on the shipped commit. Every one is a stale pin, not a defect: each was probed against the built module before its expectation was changed, and none failed for a reason other than this premise correction. Kept as its own commit per CONTRIBUTING — a test-fixture correction made stale by a production change must not ride inside another commit, because the release-sdk hotfix cherry-pick filter routes by subject prefix and a correction buried under the wrong prefix ships a half-state (v1.42.3, #3621). The most valuable one was tests/model-resolver.test.cjs's cross-provider validity invariant, which hardcoded the Codex enum as `minimal|low|medium|high|xhigh` and failed with "real API would 400". That message is now false in both directions: Codex accepts `max`, and rejects `minimal`, which no model advertises. The enum is corrected to `low|medium|high|xhigh|max` and the guard is kept intact — it is exactly the "would the real API refuse this" check worth having, and it was right to fail here. It simply carried the stale fact in its own fixture. Test NAMES were corrected alongside their assertions wherever the name asserted the old behavior — "max is Anthropic-only", "max clamps to xhigh", "minimal passthrough". A renamed test that still claims the old thing is worse than a failing one, and a green test whose name states a falsehood is how the next reader inherits the wrong premise. Both channels are covered: install-time (renderEffortForRuntime, and the generated .toml in install-runtime-artifacts) and invocation-time argv (effort-surface-axis). They were deliberately brought into agreement in this change, so their assertions had to move together. Each site carries a #3007 comment recording that Codex gained max/ultra and that capability is declared per model, so a future reader can tell this was a deliberate premise correction rather than a test bent to fit an implementation. * test(#3007): separate the effort-precedence case from the clamp case The previous stale-assertion pass over-corrected one test. It saw `effort: { default: 'max' }` on codex expecting `effort_rendered: 'xhigh'`, assumed the xhigh came from the max→xhigh clamp #3007 removes, renamed it to "max passes through" and changed the expectation to `max`. The remote runner disagreed. Reproduced against the real CLI: with that config and `gsd-planner`, the resolver emits `effort: "xhigh"`, `effort_requested: "xhigh"`, `effort_clamped: false`. The xhigh is produced by effort-resolution PRECEDENCE — gsd-planner is heavy/opus tier and its routing-tier default outranks `effort.default` — so `max` never reaches the renderer at all. The test says nothing about clamping and never did; it only looked like a clamp pin because both mechanisms happened to yield the same string. Restored to `xhigh` and renamed to say what it actually tests. It now also asserts `effort_clamped === false` and `effort_requested === 'xhigh'`, which is what makes it impossible to mistake for a clamp pin again: those two fields prove the value is what the resolver produced rather than something the renderer downgraded. Before #3007 there was no way to tell the two apart from the output — which is precisely why the previous pass could not tell them apart either. Added the test that was actually missing: `effort.agent_overrides`, which outranks the tier default, so the requested level genuinely reaches the renderer and `max` survives to `effort_rendered` end-to-end through the real CLI. Verified by probe before asserting. One test now pins the precedence rule and the other pins the #3007 behavior, and neither can be read as the other. That the clamp-visibility fields are what resolved this is a small argument for having added them. * chore(#3007): backfill changeset pr number to 3765 * test(#3007): put model-catalog under the mutation gate The Stryker shard showed as `skipping` on this PR despite the diff rewriting model-catalog's effort logic. That was legitimate, not a detection bug: `model-catalog` was never in scripts/mutation-matrix.cjs's COVERED map, so the whole module — including everything #3007 touches — sat entirely outside mutation scoring with has_work "false". Registered, with a dedicated spawn-free surface. tests/model-catalog.unit.test.cjs is new: 44 in-process tests, no runGsdTools, no child process, no filesystem, no temp dirs. That shape is not stylistic — it is the #2790 precedent this file already documents. Stryker's command runner treats a whole `node --test <file>` invocation as ONE test costing whatever its slowest case costs, and re-runs it per mutant, so pointing a shard at tests/model-resolver.test.cjs (which uses runGsdTools throughout) would reproduce exactly the 15-minute shard-cap cancellation #2790 hit. The integration file is unaffected and keeps running in full in the normal test job. Coverage spans the module rather than only the diff, because the score is measured over the whole file: effort rendering across every model and ladder level in both channels, the prototype-chain host guard, the exported enums and maps, isAnthropicFlavoredModel's provider namespacings, the profile projections, nextTier, and mergeEffortTierDefaults. The last two were nearly left out and are worth naming — every uncovered exported function is score given away, and mergeEffortTierDefaults turned out to have a genuinely interesting contract (#3531: a partial override merges over the built-ins rather than replacing them, and isValid gates the VALUE, not the tier name, so an unknown tier key is still merged in). Every expectation was probed against the built module before being asserted. minScore is 1 and that is a PLACEHOLDER, flagged as such in the registry comment. Floors in this repo are measured, not chosen — the existing entries sit at 94, 75 and 56 — and they can only be measured in CI, because mutation shards run `node --test`, which is hard-blocked locally. The first CI run on this branch reports the real number and the floor gets ratcheted to it before merge. A placeholder of 1 reaching `next` would make the gate decorative: it would pass whether or not a single mutant is ever killed. Note the target is "never regress from measured", not a fixed 80 — planning-inspect sits at 56 and is documented as an accepted ratchet candidate. * test(#3007): bootstrap model-catalog's mutation floor legally The placeholder floor was structurally illegal and the remote run said so. tests/mutation-matrix-ratchet.test.cjs guards the guard: every COVERED module must carry a matching RATCHET_BASELINE entry in the same diff, minScore must EQUAL that baseline, and it must be at least 50. `minScore: 1` failed all three. That is the ratchet working exactly as intended — a floor nobody can satisfy accidentally is the point of it. Bootstrapped at 50 in both places. Fifty is not a measured score and the comment says so plainly: it is the minimum the guard permits, and it coincides with Stryker's own configured `break` threshold, so it is the lowest legal starting point for a module that has never been measured. It still must be ratcheted to floor(measured) - 1 before this PR merges. Also corrected a real defect in the file's own instructions. "HOW TO UPDATE" step 1 read "Run the per-module Stryker shard locally" — which cannot be done here, and which the same file contradicts eighty lines further down, where the #2790 scores are recorded as "not a local run; mutation shards run `node --test`, hard-blocked in this repo's local environment". stryker.config.mjs confirms the command runner invokes `node --test` once per mutant, and .claude/hooks/block-local-node-test.sh denies exactly that. So the documented first step sends the next contributor at a wall. Rewritten to describe the path that works — push, read the measured score off the CI shard, then set the floor and its baseline together in one diff — and to say why local measurement is not available, so nobody rediscovers it the slow way. GOODHART SAFETY is untouched. The two-step is inherent to the environment rather than a shortcut: a floor cannot be measured before the first CI run exists, and the guard rightly refuses to accept an unmeasured one below its minimum. * test(#3007): ratchet model-catalog's mutation floor to its measured score The shard ran in CI and reported 59.62% — 248 mutants killed, 168 survived, no timeouts, no errors (run 32605073352, job 97108869486). Floor set to 58 per this file's own rule, minScore = floor(measured) - 1, which is the same arithmetic every sibling entry used: 57.03 to 56, 76.58 to 75, 95.65 to 94. Both halves moved together, because the ratchet guard asserts minScore equals its RATCHET_BASELINE entry and would reject them drifting apart. The spawn-free unit surface is vindicated by the clock: 57 seconds, against a 15-minute shard cap and a 9m46s frontmatter shard in the same run. That was the whole reason for creating tests/model-catalog.unit.test.cjs rather than pointing the shard at tests/model-resolver.test.cjs — #2790 recorded shards being CANCELLED at that cap when they targeted a runGsdTools-heavy integration file. The registry comment is rewritten rather than deleted. It previously warned that the floor was provisional and must not ship that way; leaving that text next to a measured floor would make the file lie in the other direction. It now records the measurement the way the sibling entries do, including that 59.62 sits below TARGET (80) and is therefore a ratchet candidate like planning-inspect at 56 — comfortably clear of its own floor with real room to grow. Raise it as the tests improve; never lower it. Worth stating plainly: 168 surviving mutants is not a clean bill of health. It is an honest floor for a module that had NO mutation coverage at all an hour ago, and it is now pinned so it cannot silently regress. --------- Co-authored-by: sim <sim@local>	2026-08-22 20:51:55 -04:00
Tom Boucher	3fd03bec4c	fix(#3760): refuse a legacy-key migration into a non-object config section (#3767) ... * test(#3760): failing-first regression for non-object config section Locks the contract from the issue's Expected section before any fix exists: a legacy-key section holding a string, number, boolean or array must be preserved verbatim, reported, and never persisted in an expanded form. Covers both blocks the issue names (branching_strategy -> git.*, sub_repos -> planning.*), the migrateOnDisk multiRepo branch that shares the shape, and the loader write paths that are what actually reach the user's config.json. Includes the negative-space cases that must keep hoisting ({} , null, absent section, canonical-nested-wins) and two fast-check properties. Refs #3760 * fix(#3760): refuse a legacy-key migration into a non-object config section normalizeLegacyKeys hoisted a legacy top-level key into its canonical nested section by spreading `result[section] ?? {}`. `??` guards only null and undefined, so a section holding a string was enumerated by index — `{...'main'}` is `{0:'m',1:'a',2:'i',3:'n'}` — while a number or boolean spread to `{}` and the value vanished. Because a fired block always pushed a Normalization, and every caller treats a non-empty normalizations array as 'config is dirty', that shape was written back to .planning/config.json and the original value became unrecoverable. Both blocks the issue names are fixed via one shared hoistLegacyKey helper, plus the two further sites that share the shape and are reachable from the same input: migrateOnDisk's multiRepo branch, and the loader's two `if (!planning) planning = {}` guards, where a non-empty string is truthy and the following assignment threw a strict-mode TypeError that the enclosing catch swallowed — discarding the user's entire config. A present non-object section now blocks its own migration. The section, the legacy key, and the file are left byte-identical; no Normalization is pushed, so nothing marks the config dirty; the refusal is reported in-band as `skipped[]` and out-of-band through the ADR-1411 warnUnusableInput seam (new frozen reason config_section_not_object). null and undefined keep their long-standing 'absent' meaning and still create the section. This is the nested-section analog of the ADR-227 shape check _readConfigFile already performs on the top-level document: valid JSON is not a config object. isConfigSection is exported and shared by both modules rather than copied. Fixes #3760 * fix(#3760): keep the multiRepo marker when planning cannot receive it Follow-up from the isolated adversarial review, and the same defect class as the two blocks the issue names — in the block it did not name. normalizeLegacyKeys block 3 deleted `multiRepo` and pushed a Normalization before anything consulted the planning section, deferring 'can this section receive sub_repos?' to the caller that runs filesystem detection. By then the marker was already gone and the config was already dirty, so with {"multiRepo":true,"planning":"docs"} the loader wrote the file back with multiRepo removed, the sub_repos injection silently no-opped against the string, and no diagnostic was emitted at all. migrateOnDisk warned for the same input; the ~30-caller loadConfig path did not. Section validity is knowable from the parsed config alone — detection is only needed for the VALUE, not for whether the destination can hold it. The refusal moves into block 3: the marker is kept, no Normalization is pushed, and a skipped entry is recorded, so all three callers inherit the preservation and the diagnostic together. The caller-side guards drop to pure narrowing. Also from review: skipped[] now reports sectionType ('string' | 'number' | 'boolean' | 'array') instead of sectionValue. migrateOnDisk's report is printed verbatim by `migrate-config`, and this module already masks config values on the set/unset output path; the type is the whole diagnostic and the value is still in the file. And `migrate-config --raw` no longer answers a refused migration with 'No legacy keys found — config is already canonical.' Legacy keys WERE found and declined, and the decline is the one thing only the user can fix by hand. Refs #3760 * fix(#3760): keep configuration.cjs dependency-free; emit from its callers The remote matrix caught a regression my own change introduced: adding `require('./unusable-input.cjs')` to configuration.cts broke the #3571 install-layout contract. `configuration.cjs` must load from a layout holding only itself plus bin/shared/*.manifest.json — the installer does not co-locate arbitrary siblings — so the new require failed at load time: Cannot find module './unusable-input.cjs' Require stack: - /tmp/gsd-3571-.../.codex/gsd-core/bin/lib/configuration.cjs pinned by 'co-located bin/shared manifests let configuration.cjs load without sdk/shared' in tests/install.test.cjs (3 failures). The contract is deliberate and the test is right, so the module goes back to zero sibling requires and the out-of-band diagnostic moves to the callers that already carry a dependency budget and hold the resolved path: cmdMigrateConfig (config.cts) and loadConfigResolved (config-loader.cts). normalizeLegacyKeys keeps reporting refusals in-band via skipped[], which is what lets it be pure and dependency-free at the same time. The emission-count and dedup assertions move to tests/config-loader.test.cjs, where the diagnostic now originates. A new assertion pins the inverse for the module itself — migrateOnDisk must emit ZERO diagnostics while still reporting skipped[] — so regrowing a sibling require fails a unit test instead of only the install suite. CONTEXT.md records why the emitter is the caller. Refs #3760 * chore(#3760): backfill changeset pr number to 3767 --------- Co-authored-by: sim <sim@local>	2026-08-22 18:57:19 -04:00

Expected RED on this commit -- next carries 32 unrostered surfaces, which is the defect the gate exists to catch. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3762): enforce docs/INVENTORY.md roster rows, backfill 32 gaps docs/INVENTORY.md calls itself the authoritative roster of every shipped GSD surface, and CLAUDE.md's inventory-drift rule requires both a roster row and a manifest regen. Only the manifest half was anchored, so a PR could ship a surface, regenerate the manifest, omit the row, and stay green -- as PR #3758 did with gsd-core/references/planner-coupling.md. Adds the roster half to tests/inventory-manifest-sync.test.cjs, backed by a pure matcher in tests/helpers/inventory-roster.cjs, and backfills the 32 surfaces already missing rows on next. Fixes #3762 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3762): harden roster matcher against fenced blocks and trim exports Skips fenced code regions when splitting level-2 sections so a documented '## ' example inside a fence cannot truncate a family section (false red) or contribute a phantom row (false pass); makes the heading pattern linear rather than a backtracking lazy match; narrows the module surface to the three names the gate consumes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3762): close two false-RED gaps found in orthogonal review Indented headings: CommonMark permits an ATX heading to carry 1-3 leading spaces, and a ^##-anchored pattern read such a document as having no family sections at all -- reporting all six missing, a structural red for zero real drift. Reproduced, then fixed and pinned. Link-wrapped cells: a row written as [`x.md`](../x.md) was not recognized, though docs/INVENTORY.md already uses that form elsewhere. Unwrapping now peels a whole-cell link and a whole-cell code span, and only layers that wrap the cell entirely -- a file mentioned mid-prose is still not a row, so the false red is not traded for a false pass. Adds a second fast-check property over the commands source-link rule, the one family whose matching rule differs from the other five.

Nothing in the tree references it (verified by Grep across the repo), package.json's files array excludes root-level files so it never shipped, and lint-removed-but-needed confirms no surviving reference.

Tom Boucher	9a69a86f42	enhance(#2971): strict planning filter mode for /gsd-pr-branch (#3720) ... * test(#2971): failing-first suite for the pr-branch planning-path filter Binds the not-yet-built planning.pr_strict mode and the corrected filter recipe for /gsd-pr-branch across six layers: pure classification and forbidden-path predicates, real-git fixtures that run the cherry-pick filter loop end to end, config-key registration through the real CLI and both manifests, the executed worktree-materialization claim the issue's triage asked to establish, fast-check properties over arbitrary path sets, and a drift guard over the shipped workflow. Two live defects in today's shipped recipe are pinned as regressions, both reproduced empirically first: `git rm -r --cached` stages a deletion of any .planning/ path the target branch already tracks, so the generated PR removes the base branch's planning files; and the same command leaves the cherry-picked file untracked on disk, so a second commit touching that path aborts the pick with "untracked working tree files would be overwritten" and every remaining commit is silently dropped. The test helper parses the canonical path lists out of gsd-core/workflows/pr-branch.md rather than restating them, so the workflow stays the single source of truth and the suite cannot drift from what ships. Refs #2971 * feat(#2971): strict planning filter mode for /gsd-pr-branch Adds planning.pr_strict — a boolean, default false, that selects what /gsd-pr-branch means by "filtered". Default mode is unchanged: structural planning state survives into the PR branch and the nine transient subdirectories do not. Strict mode drops every .planning/ path, structural files included, and carries a commit over only when it touches at least one file outside .planning/. Strict mode is what makes planning.commit_docs: true safe for a project that versions its planning tree locally but publishes none of it. The alternative posture, commit_docs: false, silently costs parallel executor isolation — a worktree is checked out from a commit, so an untracked or ignored .planning/ is simply absent inside it and the executor has no PLAN.md to read. That claim is now established by an executed fixture rather than inherited. The two path lists are declared once and both projections derived from them, so create_pr_branch and verify can no longer disagree about what the filter promised. verify previously counted every .planning/ path against a documented success criterion of zero while create_pr_branch was specified to preserve five structural files, so a correct run reported itself as failed on every phase that touched STATE.md — which is every phase. It now asserts against the active mode, and names the .planning/ paths default mode deliberately keeps rather than trading a wrong signal for silence. Two verified defects in the same recipe are fixed alongside, because strict mode would have amplified both. `git rm -r --cached` staged a deletion for any .planning/ path the target branch already tracked, so the generated PR removed the base branch's planning files — under strict mode that would have been the entire tree. The same command left the picked file untracked on disk, so a second commit touching that path aborted the cherry-pick with "untracked working tree files would be overwritten" and every remaining commit was silently dropped. Both were reproduced against real git before being fixed. The filter now forces excluded paths back to what the PR branch's HEAD carries, in the index and the working tree; a conflict outside the filter halts instead of being improvised past; a commit left empty by filtering is skipped rather than failing. A clean-working-tree precondition makes the worktree half safe. Closes #2971 * fix(#2971): unwind the checkout on a conflict halt, and test the real recipe Two review findings, both fixed in place. The isolated adversarial pass found that the conflict-outside-the-filter branch exited while leaving the user checked out on the half-built PR branch with cherry-pick state still live — this loop runs in the user's own working directory, so stranding them there is a real cost even though it is not a vulnerability. The branch now aborts the pick, returns to the original branch, removes the partial PR branch, and says so before exiting. The standards pass found the L2 fixtures executed a hand-written mirror of the cherry-pick filter recipe rather than the recipe itself, so a reordering in the workflow would not have been caught — and the order is load-bearing, since restoring a path from HEAD before removing it inverts the filter. The helper now extracts the canonical loop from the shipped workflow and the fixtures execute that verbatim, which also gives the conflict-halt unwind above real coverage. The drift guard additionally pins the two commands' relative order and asserts the workflow carries exactly one canonical loop. Also records the publication gate in the CONTEXT.md glossary next to the commit gate it is distinct from. Refs #2971 * fix(#2971): make the conflict-halt unwind actually unwind, and use the colon slash form The remote matrix caught two defects in the previous commit. The halt path claimed to restore the original branch but did not. `git cherry-pick --abort` does not apply to a single `--no-commit` pick with no sequencer file, and the fallback left the unmerged index in place, which makes `git checkout` refuse — a failure the `2>/dev/null || true` then swallowed, so the user was told they had been restored while still sitting on the half-built PR branch. The unwind now drops sequencer state, hard-resets the disposable PR branch to clear the unmerged index, and only claims a restore when the checkout actually succeeded; when it does not, it says where the user is and gives them the two commands to finish it by hand. Verified against real git: exit 1, the conflict named, HEAD back on the original branch, the partial branch gone, a clean tree and no CHERRY_PICK_HEAD. Two runtime-loaded source artifacts used the retired `/gsd-<cmd>` hyphen form, which names a command no runtime registers. The canonical authoring token for workflows and references is `/gsd:<cmd>`; docs keep the hyphen form, so the documentation added in this branch is unaffected. The comment in src/config.cts moves to the colon form too, since it propagates into the generated lib.

Tom Boucher	14679b866b	enhance(#2856): add default-off live-DOM UAT capability (#3716) ... * test(#2856): add failing-first suite for the live-dom-uat capability Binds the approved triage shape before any of it exists: - containment — the execute:wave:post hook must not render unless workflow.live_dom_uat is true AND the capability resolves active (fail-closed on a missing state entry, and on a non-boolean value) - criterion 4 — agents/gsd-executor.md carries no browser MCP family; asserted as an absence, which is the only way it is observable - Hyrum guard — the pre-existing mcp__playwright__* branch must stay outside the key-gated block, or upgrading silently removes working automated UI verification for every current Playwright-MCP user - parity — the browser glob list now lives in two surfaces (agent frontmatter + workflow detection block); the assertion fails if either gains or loses a family without the other Red by construction: the capability, agent and workflow block do not exist yet. Verified on the remote runner. Refs #2856 * enhance(#2856): add default-off live-DOM UAT capability A phase whose acceptance criteria needed a live DOM could not be finished by the agent that executed it: gsd-executor carries no browser tools, so it correctly returned checkpoint:human-action even though the work was not human-only, just tool-less. Every such phase degraded to "executed, then finished by hand in the orchestrator", and autonomous: false could not distinguish "a human must judge this" from "the executor lacks the tool". Implements the shape approved at triage, not the one reported. The executor's tools: line is NOT widened, in any configuration: for a first-party agent the static list is the only control that exists (ADR-1244 D2, ADR-857 D4, no per-dispatch override). Instead one default-off capability owns the key, the agent, and the step: - capabilities/live-dom-uat/ — activationKey workflow.live_dom_uat (boolean, default false), one additive step at execute:wave:post (onError: skip, gates: []), so it can never halt a wave - agents/gsd-dom-verifier.md — the only GSD agent carrying browser MCP globs, in its own tools: line, with no Bash - verify-work automated_ui_verification — a gsd:live-dom-families block naming both new families AND the key; presence alone never activates Two independent fail-closed gates: isCapabilityActive renders a hook only on state.active === true, plus the step's own `when`. The pre-existing mcp__playwright__* branch keeps the gating it already had and stays outside the new block. Pulling it behind a default-off key would have silently removed working automated UI verification from every current Playwright-MCP user on upgrade. Also closes a host gap this surfaced: execute:wave:post dispatched only contribution + gate, so ANY registered step was declared and silently never run — exactly the single-kind hand-roll loop-hook-dispatch.md names. Step 5.75 now dispatches every kind == "step". The browser-profile lock is tolerated, not coordinated: --isolated is a flag on the operator's own MCP-server registration that GSD neither launches nor parameterizes, so the verifier reports could_not_look / profile_locked, names the flag, and stops. DOM-VERIFY.md keeps could_not_look and nothing_to_report distinct behind a closed reason enum — collapsing them is the ambiguous-run-notes defect reported. Verified on the remote runner. Closes #2856 * fix(#2856): apply review findings from the orthogonal passes Correctness pass (blocker): - delete detectionBlockIsCrlfSafe. It was pass-always: it read the file, replaced LF with CRLF, then indexOf'd marker strings that contain no newline, so the replacement could not change the result and the assertion could never fail for the reason it stated. There is no real CRLF risk on this surface either — the gsd:live-dom-families block has no parser, only human and agent readers. Deleted rather than replaced, per the repo's pass-always-test rule. Isolated security pass (two minors, both real): - execute-phase.md step 5.75: this change is what first activates kind == "step" dispatch at execute:wave:post, which newly opens the ref.command shell path at that loop point. Our own step uses ref.agent and never touches it, but the door is now open, so the step-dispatch line carries the same in-context validate-before-shell warning the sibling gate-dispatch line directly below it already carries. - gsd-dom-verifier: quoted page text in DOM-VERIFY.md is attacker influenced. Require it wrapped in inline code or a fence, kept short, and never left reading as a directive to the next reader. Verified on the remote runner. Refs #2856 * fix(#2856): settle the new-agent roster ripple Checkpoint 2 returned 28 failures, none in the new suite — all of them the guards that exist to make adding an agent a deliberate act. Each is a real boundary that had to move: - docs/AGENTS.md: Tools row must copy the frontmatter verbatim (#2526), so the browser globs lose their backticks; primary-agent counts 21->22, roster 33/34->34/35, Verifiers category 1->2 - docs/INVENTORY.md: roster completeness requires every agents/gsd-*.md to be classified exactly once - gsd-dom-verifier: add the anti-heredoc instruction and the commented hooks: frontmatter pattern both agent gates require - gsd-core/bin/shared/model-catalog.json: every shipped agent needs a profile entry (#3229) - copilot-install / kilo-upgrades / qwen-upgrades: expected agent list and the 34->35 roster boundary - execute-wave-post-gate-pipeline-e2e: execute:wave:post legitimately carries one step now. Asserted as an exact shape — one step, capId live-dom-uat, ref.agent gsd-dom-verifier, onError skip — so it stays a real guard against accidental change rather than being relaxed Two findings worth naming: mcp-tool-inheritance (#2526) rejected the agent for documenting mcp__playwright__* while its tools: line withholds it — a dead instruction that invites the agent to claim a path it cannot take. The prose now names the Playwright MCP family without the dispatchable token, in both the agent and the capability fragment. runtime-launcher-parity rejected the new gsd_run call: each fenced block is its own shell, so a workflow step file invoking gsd_run needs its own canonical preamble. Propagated with scripts/sync-runtime-launcher.cjs. That script also normalizes explore.md, which is unrelated pre-existing drift the parity check tolerates, so it is reverted to keep this diff scoped. The emitted-drift ack supersedes the spent #3370 entry for execute-phase.md — it is merged into next, so its ripple is absorbed at the base and it can no longer clear anything. That is the same supersede the #3370 entry itself performed on the spent #3324 fragment. Its unrelated execute-plan.md entry is untouched. Verified on the remote runner. Refs #2856 * fix(#2856): drop the stale emitted-drift ack entry The automated-ui-verification.md entry was written speculatively rather than from a reported growth, and the check names that precisely: an ack "written or reworded in THIS diff, but nothing here needed it, so it explains nothing". The growth tier keys on the bare filename as it appears under gsd-core/workflows/ or agents/. automated-ui-verification.md is nested under verify-work/steps/, so it was never in the tracked set — only execute-phase.md was ever reported, both before and after the launcher preamble landed.

Tom Boucher	8da2dd3ad2	feat(#2790): add read-only planning.inspect schema-v1 snapshot query (#3708) ... * feat(#2790): add read-only planning.inspect schema-v1 snapshot query Adds a read-only query emitting a schema-versioned JSON projection of .planning/ so downstream harness UIs can consume planning state without parsing GSD's Markdown a second time. Composed strictly from the ADR-3180 section 7 owners plus parsePlanDocument, parseRequirements and parseUatItems; markdown structure is read through the Markdown Sectionizer and Markdown Table Model seams. It declares its own flat external schema rather than serializing PlanningSnapshot, which is the diagnostic-rule subject and still growing. Extracts plan-document parsing out of cmdPhasePlanIndex into a shared leaf module so phase.plan-index and planning.inspect cannot drift, including the plan-id derivation both surfaces report. Also fixes parseRequirements dropping the separator delimiter used by the shipped requirements template, surfaced while wiring the requirement rows. * fix(#2790): close spec gaps and a raw-text test assertion found in review Review findings from the standards, spec and security passes: - phases[] rows carry goal and dependencies, the two per-phase elements the issue Summary names that had no corresponding field. Goal is bounded to the section's leading prose so the Depends-on line, the Plans checklist and the wave annotations are not duplicated into it. - requirement rows carry their own diagnostic codes, so a consumer no longer has to string-parse the global diagnostics subject to correlate. - roadmap_acceptance.checkbox is looked up through the phase-id key owners. It was compared raw against the on-disk directory name, so it read null for every real-world slugged phase directory and the evidence channel was inert. - the hostile-input test asserts the structured payload instead of matching the raw stdout string. The absence proof over raw stdout is kept deliberately. * fix(#2790): register planning in the runtime usage list and repair fixtures Remote runner reported 9 failures on 9b3f9aa. Two root causes, both fixed: - gsd-tools.cjs registered the planning family in HOST_COMMAND_ROUTERS but never added it to TOP_LEVEL_USAGE's Commands list. Those are two surfaces a parity test guards, and the top-of-file block comment is not the runtime help string. A real wiring gap that every local gate and three review passes missed. - the new suite's fixtures could not produce a resolvable phase set. STATE.md frontmatter omitted the milestone field, which ADR-3180 7.2 rule 1 makes the primary milestone selector, so the phase set scoped unscoped and every percentage was correctly withheld. Separately declarePhase returned a path without creating the directory, so a phase declared but never written to left phases empty. Both reproduced against the built module before fixing. No assertion was weakened. The withholding path is still exercised and still returns null when the roadmap is absent. * chore(#2790): backfill changeset pr number * test(#2790): cover every enumerated matrix row and contain a symlink escape Reverses a silent deferral. An earlier revision left 23 of the 78 enumerated matrix rows unimplemented and 7 more as one-off manual checks, with a paragraph in the artifact and the PR body describing the gap. CLAUDE.md is explicit that such a note is not a fix and is not surfacing. The rows are implemented instead and the manual-evidence bucket is gone: 49 test cases become 88, covering all 78. Writing the symlink row proved a real leak: a *-PLAN.md symlinked outside .planning/ had its content emitted into the payload, confirmed via a direct call and the spawned CLI. readDocument now resolves target and planning root with realpathSync and rejects an escape, returning the ordinary unreadable-document shape. Tested both ways, because a containment check that over-rejects is its own defect: an escaping symlink leaks nothing and degrades that plan alone, while a legitimately relocated .planning/ symlink stays fully readable. The three new modules are registered in the mutation COVERED registry, which had been reporting has_work false and skipping the Stryker gate entirely. Provisional non-binding floors so the shards run and report; raised to the measured value before merge, since the registry forbids calibrating from a local run. * fix(#2790): satisfy the mutation ratchet contract and scope the 1MB test Remote runner reported 16 failures on 8c451ed. Two causes. The COVERED registry has a paired contract the earlier commit violated: every module needs a matching RATCHET_BASELINE entry, and minScore must be between 50 and 100 with minScore === baseline. The provisional floor of 1 was illegal on both counts. All three modules now sit at 50 — the registry's own enforced minimum — with matching baselines. The score cannot be measured locally: the shard runs node --test, which this repo hard-blocks, so CI is the only source. Floors are raised to the measured value once this PR's shards report; a shard below 50 means the tests need strengthening, since the floor cannot go lower. The 1MB test was measuring the test harness rather than the product. The command handles the oversized payload correctly by spilling to a tmpfile and resolving it back, but the resolved stdout then exceeds runGsdTools' maxBuffer and the helper reports ENOBUFS. It now uses --pick so stdout stays one byte while the full 1MB document is still read and parsed end to end. * fix(#2790): wire containment across every document read this command drives An isolated security review of the containment control found the boundary logic sound but not comprehensively wired: two content reads reached the filesystem without it. An escaped phase DIRECTORY could enumerate external filenames into the file fields and diagnostic subjects. Both enumeration sites now containment-check the directory before reading. Worth recording that the leak was already prevented one layer earlier than the review claimed: Dirent#isDirectory() reports false for a directory symlink, so such a directory never becomes a phase row at all. The guard is defense-in-depth for a direct caller and for platforms where a reparse point reports as a directory. A *-VERIFICATION.md symlinked outside the root leaked one frontmatter value verbatim, because readVerificationStatus does its own read and copies an unrecognized status into the payload's next_action. Closed from the consumer side through that function's existing fs injection seam, so src/verification.cts keeps its signature and its other callers are untouched. The reviewer additionally rated a forged status: passed as an integrity bypass. It is not: anyone able to plant the symlink can plant a real VERIFICATION.md saying the same thing. The incremental risk is confidentiality, which is what these fixes close. src/plan-scan.cts is deliberately unchanged: isPlanSuperseded reads symlink-followed content but yields only a derived boolean, no document text. * test(#2790): give the mutation shards an in-process surface Two Stryker shards were CANCELLED at the 15-minute cap, not failed on score. CI log: 640 mutants instrumented, and the dry run reported 'Ran 1 tests in 20 seconds' because the shards pointed at the integration suite, where nearly every case spawns a gsd-tools subprocess and Stryker's command runner treats the whole test-runner invocation as a single test. 640 x 20s cannot finish in 15 minutes; at the kill it was 27/640 with an ETA over an hour. Every other COVERED module points at a property or unit file, and the workflow's own paths filter lists exactly those two patterns. In-process is the intended mutation surface; the shards were pointed at the wrong shape of test. Adds tests/planning-inspect.unit.test.cjs — 39 cases in 10 describes that spawn nothing and call the built modules directly. plan-document and the router need no filesystem at all, one being a pure content-to-object parser and the other taking an injected mock. The three shards now point here. The 91-case integration suite is untouched and still runs in the normal test job. * chore(#2790): ratchet mutation floors to the measured CI scores CI run 32392791843 measured all three shards, which is the only source the registry accepts — local runs count timeouts as kills and inflate badly. planning-command-router 95.65 -> floor 94 plan-document 76.58 -> floor 75 planning-inspect 57.03 -> floor 56 Applied the registry's own rule, floor(score) - 1, and updated RATCHET_BASELINE to match, since the ratchet test enforces equality. planning-inspect sits well below the file's target of 80 and is the obvious ratchet candidate as its tests improve. planning-command-router already exceeds the target. The placeholder comment about floors pending measurement is removed rather than left standing as a false statement. --------- Co-authored-by: sim <sim@local>	2026-08-20 13:42:43 -04:00
Tom Boucher	77fa08f1e8	fix(#2773): feed the spec-phase edge probe English-translated requirement text (#3713) ... * test(#2773): failing-first contract and premise tests for translated edge-probe input Locks the Step 5.5 contract that a response_language project must feed the edge probe an English translation of each requirement's text, and binds that advice to measured engine behavior: the same requirement classifies to zero shapes in Portuguese and to collection/adjacency/empty/ordering in English. Also pins the honest limit — the issue's own repro sentence classifies to [] in English too, so translation is necessary but not sufficient and the authored shapes override is the documented fallback. Red before the doc change; the assertions are all false today. Refs #2773 * fix(#2773): feed the spec-phase edge probe English-translated requirement text The shape cues in src/edge-probe.cts are English word-boundary regexes, so a project running with response_language set wrote its SPEC requirements into the Step 5.5 $REQS_JSON heredoc in that language, matched no cue, classified to zero shapes, and landed every row in the unclassified sentinel (#1110). The taxonomy contributed nothing and --auto left it all unresolved — the probe was a silent no-op for exactly the spec type it exists to harden. Step 5.5 now states that the $REQS_JSON payload is engine input rather than user-facing output, so the response_language rule does not govern it: each requirement's text carries a faithful English translation, the SPEC keeps its original language, and requirement ids are never translated or renumbered. The instruction sits before the heredoc on purpose — the downstream APPLICABLE=0 warning fires only when every requirement is unclassified, so a partly-classified non-English spec would otherwise slip through with no signal at all. Measured against the compiled engine: the same requirement returns [] in Portuguese and collection -> adjacency/empty/ordering in English. Also measured: the issue's own repro sentence returns [] in English too, so translation is necessary but not sufficient — the instruction therefore points at the authored shapes override for prose carrying no cue in any language rather than promising that translation restores classification. Doc scope only, per the triage disposition on the issue. The compiled engine is untouched; the lang-hint / per-language cue-set fix is a separate follow-up. Closes #2773 * fix(#2773): clean up the edge-probe temp file on the placeholder-guard exit path Surfaced by the isolated security review of this branch. Between the mktemp and the unconditional cleanup, Step 5.5 has two sibling guards that disagreed about their own invariant: the engine-failure guard runs rm -f "$REQS_JSON" before exiting, while the empty/placeholder guard directly above it exited without one. A spec run that tripped the placeholder check therefore stranded a temp file holding the SPEC's requirement text in TMPDIR, once per failed run. The added contract test walks the region between the mktemp and the unconditional cleanup and asserts no exit path leaves the file behind, so the two guards can no longer drift apart. Proven to bind: run against the pre-fix file the walker reports the leaking exit; against the fixed file it reports none. Refs #2773 * docs(#2773): record the edge probe's English-cue input constraint in the predicate store The co-change gate flagged CONTEXT.md (13 co-changes with spec-phase.md) and docs/CONFIGURATION.md (11) as candidate-missing-updates, and both were real gaps rather than incidental coupling. CONTEXT.md's EdgeCompletenessProbeModule entry documents the input contract for classifyShape but did not record that SHAPE_CUES are English word-boundary patterns — so the predicate store implied text was language-agnostic, which is what a future agent reads before touching this seam. docs/CONFIGURATION.md's response_language row is what a non-English project reads when it turns the setting on; it now names the one deliberate exception and links to the FEATURES.md explanation, so the interaction is discoverable from the config key rather than only from the workflow. CONTEXT-INDEX.json regenerated via gen-context-index.cjs --write. The drift-ack fragment is updated for the final byte range and now also records the placeholder-guard cleanup fix folded into the same block. Refs #2773 * fix(#2773): append the growth rationale to the existing spec-phase.md ack entry The remote runner caught this: emitted-attribution.test.cjs pins the 0000-legacy-migration.json spec-phase.md entry permanently (the #2914 migration regression test asserts the exact '31987 -> 31997' delta text survives), so removing it to avoid a duplicate-key collision with a new fragment broke that test instead of satisfying the ratchet. The entry is an accreting log, not a single-use slot — #2733, #3132 and #3102 were each appended to the same reason string by later PRs, which is how a shared growth key coexists with the rule that two ack sources may never name the same path. This appends the #2773 rationale the same way and drops the separate fragment, whose spec-phase.md key was the collision. Verified locally by reproducing both affected tests against the real fragment before re-dispatching: the pinned delta survives, grown[0].acked is true, staleAcks is empty, and all 35 entries still read as spent. Refs #2773 * docs(#2773): add a how-to for probing edges in a non-English project The phase gate's enablementSequence check caught a wrong call of mine. I had recorded that no how-to was owed because the user takes zero extra steps — the workflow translates the probe input itself. Written out, though, the sequence from off to value is two steps and step 1 depends on response_language, a setting owned by a different capability than the edge probe, which is exactly the condition the how-to test names. There is also real task content a reference table cannot carry: the three-way split between a few unclassified rows (the classifier's recall gap), every row unclassified (the probe could not read the spec at all), and the silent partly-classified case where the APPLICABLE=0 warning never fires. That last one is what a user would otherwise misread as a clean bill of health. Shaped after the resolve-edge-coverage-findings / resolve-unreachable-guard siblings and indexed from docs/README.md next to its closest relative.

Tom Boucher	adb46cdd85	feat(#2734): surface STATE.md commit-age on the statusline (#3700) ... * test(#2734): failing-first suite for the statusline STATE.md freshness marker Binds the contract before any hook change exists: a `state ~N commits back` segment gated on the state_head stamp landed by #2622, firing at the same advisory threshold /gsd-health's W024 uses rather than at > 0. Covers all five acceptance criteria — threshold parity (19/20/21 boundaries), both renderers including formatGsdStateCompact, an exact spawn-count assertion, repo-pinning and sub_repos degradation, and behavioral parity against readStateHeadFreshness rather than a source-grep of the two fence copies. 52 example-based tests plus 5 seeded fast-check properties. Red now by design. * feat(#2734): surface STATE.md commit-age on the statusline Adds an opt-in `state ~N commits back` marker to the GSD-state segment, consuming the `state_head` stamp and freshness contract landed by #2622. A solo developer returning to a project reads "Phase 4, executing" in STATE.md and acts on it, without noticing the codebase moved 40 commits since that line was written. /gsd-health reports it as W024, but only if you think to run it; the statusline is the surface you see without asking. Fires at STATE_HEAD_ADVISORY_COMMITS (20), the same threshold W024 uses, not at > 0: with commit_docs:true the commit carrying a STATE.md sync advances HEAD by one, so > 0 would alarm permanently on a fresh project. Costs exactly one bounded git subprocess per render and none when disabled. `rev-list --left-right --count` answers ancestry and distance together, and repo pinning is a filesystem check mirroring projectOwnsItsRepo rather than a --show-toplevel compare, which is unreliable on macOS /private/var and Windows 8.3 paths. Every unresolvable input degrades to the tri-state unknown -- the marker is absent, never a "fresh" claim the project cannot substantiate: a malformed stamp, a root that does not own its .git, a sub_repos workspace, history rewound past the stamp, or git being unavailable. Also collapses statusline config resolution onto one resolveStatuslineOptions() seam. runStatusline() and renderStatusline() duplicated it byte-for-byte; one copy is what keeps a newly-added key from reaching only one of them. * test(#2734): route the e2e spawn through the process seam and fix fixture leaks Review findings from the two orthogonal passes: - `bothEntryPointsResolveOptionsIdentically` spawned a child and substring-matched its stdout to test a pure function. It now calls resolveStatuslineOptions() directly — no subprocess, no text matching. - `skipsFreshnessWorkWhenTodoTaskActive` genuinely needs a child (the !task gate lives in runStatusline, which reads stdin), so it now spawns through tests/helpers/process-seam.cjs and proves the negative with a filesystem fact: the git shim appends to a marker file on every invocation, and the assertion is that the marker never appears. Stronger than asserting text is missing, and it drops the last stdout substring match in the block. - Every fixture-creating test now registers `t.after(() => cleanup(dir))` instead of a trailing cleanup(dir), which leaked the temp repo on assertion failure. derivationAgreesWithStateModule reassigns `dir` across five fixtures, so it binds each directory at scheduling time rather than cleaning only the last. Also corrects markerCoexistsWithMilestoneComplete, which asserted the wrong expectation rather than finding a code defect: `percent` drives the progress bar too, so the milestone segment reads "v1.9 [##########] 100%". The marker appends after it, which is what the test exists to prove. CONTEXT.md's opt-in statusline key list was missing statusline.show_git as well as the new key; both are now enumerated. * docs(#2734): backfill changeset PR number (#3700) --------- Co-authored-by: sim <sim@local>	2026-08-20 00:35:01 -04:00
Tom Boucher	2fca0e17e4	enhance(#2554): resolve code review depth from path-scoped override rules (#3695) ... * test(#2554): failing-first suite for path-scoped code review depth overrides Binds the not-yet-built code-review-depth module: segment-aware path-prefix matching of a changed-file set against ordered {paths,depth} rules, resolution order flag > strongest matching rule > global > standard, typed validation errors, and the large-scope downgrade boundary. Also proves behaviorally that workflow.code_review_depth_overrides is not yet a registered config key. Refs #2554 * feat(#2554): resolve code review depth from path-scoped override rules Adds workflow.code_review_depth_overrides — an ordered array of {paths, depth} rules matched against a review's changed-file set by segment-aware path-prefix comparison. Resolution order is --depth= flag, then the strongest matching rule, then workflow.code_review_depth, then standard; a matching rule replaces the global rather than being max'd with it, so quick and standard rules stay meaningful. Glob metacharacters are a hard configuration error rather than sugar for a prefix, and malformed rules halt the review instead of degrading to standard. The resolver is pure and reports its own provenance, so the workflow can print the resolved depth and the rule that matched. The pre-existing >50-file deep-to-standard downgrade moves into the module and now names the rule it overrode. The key is registered centrally rather than as a capability config slice: the federated slice channel admits only boolean/string/number/enum, so an array slice would be dropped as malformed. Closes #2554 * test(#2554): correct depth-provenance assertions and pin out-of-repo paths Two corrections to the failing-first suite. The source assertion for a non-matching rule with no global configured expected 'config'; with no global set the depth comes from the default, and a companion assertion tolerated either value, so both passed against an implementation that derived provenance from whether any rules existed rather than from where the depth came from. The out-of-repo absolute-path case used a home-directory path that matched neither implementation, so it never exercised the defect it named. It now pins the discriminating cases: an absolute path outside the repo root must not match a repo-relative rule, and one under the root must. * docs(#2554): document path-scoped code review depth overrides Reference rows for workflow.code_review_depth_overrides in the configuration, features and commands references plus the locale copies that carry those tables, and in the planning-config reference. Explanation of why escalation is whole-review rather than per-file and why v1 is prefix-only. New how-to for scoping review depth by path, carrying the configuration-error reason table and the distinction between nothing to report and could not look. CONTEXT.md glossary entry and the INVENTORY row for the new CLI module. ja-JP and ko-KR CONFIGURATION.md carry no code_review keys at all, and ko-KR and pt-BR FEATURES.md carry no code-review config table, so those files are deliberately untouched. * fix(#2554): make the depth-misconfiguration halt executable and reject control chars Three review findings, all in this change. The misconfiguration halt was prose rather than shell: the error-printing fence was followed by an unconditional extraction fence, so an ok:false result threw and left the depth empty instead of stopping the review. Prose is not a guard — the two fences are now one block with a real conditional, and anything that is not the literal string true fails closed. An interior control character in a rule path survived validation and reached the provenance string and the summary box; rule paths now reject control characters via a new PATH_CONTROL_CHAR reason, after the glob check so precedence is unchanged. That in turn makes the field record safe to delimit, so the seven node invocations that each re-parsed the same result to read one field collapse to one. Also corrects the glossary entry's illustrative paths, which the glossary-ref check read as real repository references. * fix(#2554): use the fast-check v4 string API and acknowledge workflow growth Two failures from the remote matrix on d3111f45, both this branch's. The property block built its segment arbitrary with fc.stringOf, removed in fast-check v4. Because the arbitrary is constructed in the describe body, the throw took out all four property tests rather than one — they had never executed. Rewritten to fc.string({unit, ...}), the form this repo already uses in emitted-attribution.test.cjs. Every other fast-check helper in the file was audited against the installed module. The emitted-attribution growth arm needed an acknowledgment for code-review.md, which grew 5376 bytes. The pre-existing 3503 fragment keying the same file is spent — its ripple was absorbed when #3503 merged, and the base file is exactly the 34435-byte baseline this growth is measured against — so it cannot clear anything, while the ack lint hard-fails on a duplicate key across two sources. Removed it in favor of the new fragment, which is exactly how #3503 itself replaced the spent 3191 fragment. * docs(#2554): backfill changeset PR number --------- Co-authored-by: sim <sim@local>	2026-08-19 22:45:35 -04:00

Never executes command text. - gsd-tools check verify-command-paths <N>: per-phase probe, wired into plan-phase.md before the plan-check pass. - init.plan-phase gains prior_verify_commands, ungated by context_window. - gsd-plan-checker: new Verify Command Path Resolvability dimension that reports the failing target and never prescribes a replacement. Also fixes first-match-wins prefix bucketing in scripts/lint-test-file-count.cjs (readdir order is not stable across platforms, so a module whose name extends another's with a hyphen bucketed differently on Linux than on macOS). Closes #2401 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2401): ground the canonical --prefix form, quoted paths, and absolute cd resets Independent review found three defects in the recognizer: - npm --prefix DIR run SCRIPT never reached the script-existence check, because the pattern required npm and run to be adjacent. That is the form the docs tell planners to prefer, so script_missing never fired for it. The prefix flag and its value are now stripped before matching. - --prefix captured with \S+, so a quoted path containing a space was truncated to a stray opening quote and reported as a missing directory - a false blocker, worse than the bug this feature fixes. The capture is now quote-aware. - A chained cd whose later segment was absolute concatenated instead of resetting, producing a nonsense path and another false blocker. The fold now resets on an absolute segment. Also replaces the bespoke phase-directory regex with the canonical phase-id helpers. Real phase directories are NN-slug, not phase-N-slug, so the prior-command harvest matched nothing outside its own fixtures and the planner-inheritance half of this feature was dead code. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * refactor(#2401): source task blocks from the canonical sectionizer The module carried its own copy of the <task>-block grammar - a fourth hand-rolled mirror of the one markdown-sectionizer owns. verify.cts keeps its copy only because it needs the type= attribute the canonical helper discards; this module never reads that attribute, so it can share the owner outright instead of adding a test around a copy. extractAutomatedCommands now takes task bodies from extractTaggedBlocks and the out-of-task remainder from stripTaggedBlocks. A task-grammar parity test pins the attributed task-name set against the canonical helper across six awkward task shapes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2401): extract agent-file overflow to references and repair the property arbitrary The remote matrix run came back red with 19 failures, four root causes: - agents/gsd-plan-checker.md and agents/gsd-planner.md both blew the 49152 agent cap. Their bodies move to gsd-core/references/, leaving @-reference stubs, per the documented overflow pattern. - The new checker dimension invoked gsd_run before the canonical preamble that defines it. The call is deleted outright: plan-phase.md already runs the probe and hands the result in as {VERIFY_PATHS}, so the dimension consumes that rather than re-running anything. - fc.fullUnicodeString does not exist in fast-check 4.8.0. Replaced with fc.string({ unit: 'binary' }), which covers the same 0000-10FFFF range. - Three runtime-loaded files grew; acknowledged in the existing ack fragments that already own those bare filenames, since two ack sources may never name the same path. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#2401): regenerate golden install-tree fixtures for the new references Adding two files under gsd-core/references/ changes what the installer emits into every runtime's tree, so all 19 golden install-parity fixtures went stale. Regenerated with npm run gen:install-tree; the delta is exactly the two new reference paths per runtime, no removals.

The dynamic-path refusal rejected ~ anywhere, and a GitHub Windows runner's tmpdir is an 8.3 short name - C:\Users\RUNNER~1\AppData\Local\Temp - so a valid absolute Windows path came back unresolvable/dynamic_path. This was a production bug, not a test artifact: any Windows user whose project path carries an 8.3 short name, or any literal ~, silently lost the probe entirely - every command degrading to unresolvable with no explanation. ~ is a home expansion only at the start of a path; elsewhere it is an ordinary literal. The check is now split: $, backtick, *, ? and newline stay refused anywhere (substitution and globs, and the glob characters are illegal in Windows path components regardless), while ~ is refused only leading, tolerating one leading quote since the check runs before quote stripping. The prior tests only caught this on Windows because only Windows puts a ~ in tmpdir. Four new tests pin it on every platform via a fixture directory literally named RUNNER~1.

Tom Boucher	1adf6d2245	fix(#3620): point the docs at files that actually exist (#3658) ... * fix(3620): point the docs at files that actually exist docproof found 34 stale references; the reporter hand-read all 34 and reported the 8 that are real, explaining why the other 26 are deliberate (files the documents themselves label legacy or "superseded by", and one pre-Diataxis link label whose target still resolves). Those 26 are left alone — re-touching them would contradict the issue's own analysis. Every claim was re-verified against git ls-files at HEAD before editing. docs/INVENTORY.md said its roster is anchored by six drift-control tests. Five are gone (commands-doc-parity, agents-doc-parity, cli-modules-doc-parity, hooks-doc-parity in 5d8a8c4d; command-count-sync in fbf30792), so the sentence now names the one that exists. Whether one test is sufficient coverage is a maintainer question the issue explicitly declined to answer, so no new drift tests are proposed here. The four translations were a revision further behind, each naming a seventh test deleted in ae8bb707 that the English file had already dropped. All four now match. Renamed targets corrected in CONTEXT.md, VERSIONING.md, docs/CONFIGURATION.md and the update workflow. The new test names carry no issue-NNN- prefix, which is what lint-regression-test-names requires, so they are the correct targets. docs/TESTING-SUITES.md is the one that could cost somebody time: it INSTRUCTED contributors to add an acknowledgment to the legacy drift-ack file, which CONTRIBUTING.md says to never use. Rewritten from the real workflow — per-PR fragments under the drift-acks directory, and a spent base-side ack is re-armed by rewording that fragment's reason in place, never by adding a duplicate, since two sources naming one path is a hard error. docs/skills/discovery-contract.md's heading named a query module deleted in 11918dcc. The section was REMOVED rather than retargeted: its documented behavior (skip the deprecated root) is not what the surviving code does — skill-manifest includes that root marked deprecated:true — so retargeting would have documented something false. Found and fixed inline, same class: VERSIONING.md described an SDK bundling step the release workflow does not have (zero such mentions in that file); CONFIGURATION.md and four translations named a dead model-catalog triple collapsed by ADR-457. Dead config removed: the changeset lint's user-facing prefix list still carried two retired sdk entries. git ls-files -- 'sdk/*' returns nothing. No test pins that array. Left deliberately: the comment explaining the retired catalog path, the install regression test that reconstructs the old broken layout to prove it fails, and the generated test-timings cache. Each is a legitimate mention of a dead path, not drift. Note lint-removed-but-needed cannot catch this class: it diffs baseRef...HEAD, so it only sees files deleted in the change under review. These were orphaned by PRs that predate the lint. A repo-wide existence audit would need a suppression mechanism for the 26 deliberate mentions above; that is a feature, not part of this fix.

Tom Boucher	9e4f0e99ad	fix(#3631): exclude only __pycache__-resident bytecode from the consent digest (#3650) ... * test(3631): failing-first coverage for bytecode-cache in the consent hash bundleContentHash digests a walk with no exclusion, so a routine 'python3 -m unittest' inside a Python-backed capability bundle writes __pycache__ under the bundle, the recomputed hash stops matching the consent record, and the capability silently goes inactive — no error, no warning, and loop render-hooks then omits its step and gate. Two distinct triggers, and the second is the sharper one: collectBundleEntries pushes a {kind:'dir'} entry for EVERY directory and the digest emits a TAG_DIR marker for it, so an EMPTY __pycache__/ flips the hash before a single .pyc is written. A fix filtering only *.pyc would leave that live. Verified by execution against the built lib: 5 of 7 probe rows diverge from intent today, including the empty-directory row. The anti-regression rows are the point of the shape: editing a real scripts/m.py and adding node_modules/pkg/index.js must BOTH still change the hash. node_modules is deliberately not excludable — its contents are required at runtime, so dropping it from the digest would stop consent binding executable content. The symlink row pins ordering: exclusion must apply after the lstat fail-closed rejection, never before. Refs #3631 * fix(3631): exclude derived bytecode caches from the consent digest RED proven at e5ba8f1fe on the remote runner: 8 failures, exactly the rows predicted to fail, with the four anti-regression rows already green. collectBundleEntries now skips a hardcoded, gitignore-independent set from the DIGEST: basenames __pycache__, .pytest_cache, .DS_Store, and any .pyc/.pyo file. Matching is byte-exact on the raw Buffer name (the walk never utf8-decodes) and case-sensitive, so the digest does not vary with how a name happens to be spelled on a case-insensitive volume. Three properties were preserved deliberately, each pinned by a test: - The filter runs AFTER the lstat symlink/non-regular fail-closed rejection. Filtering first would have turned the exclusion into a way to smuggle a symlink past the check; a symlink named x.pyc still throws. - Excluded entries still count toward BUNDLE_MAX_FILES and BUNDLE_MAX_TOTAL_BYTES. The caps guard the WALK; the digest answers a different question, and exclusion must not become an unbounded-bytes hole. - An excluded DIRECTORY is neither emitted as a TAG_DIR marker nor recursed into. The directory marker was the sharper half of this bug: an empty __pycache__ flipped the hash before any .pyc existed, so a *.pyc-only filter would have left it live. The issue proposed either a gitignore-aware walk or a list including node_modules. Both are rejected. A consent binding must not delegate its scope to a .gitignore the bundle author does not control — one line there would drop arbitrary executable content out of the hash. And node_modules holds code that is required at runtime; excluding it would stop consent binding executable content, turning a usability bug into a supply-chain hole. What makes __pycache__ different is that CPython validates each .pyc against its sibling source, which remains hashed, so a real code change still invalidates consent. Docs: CONTEXT.md's 'EVERY regular file AND directory' claim is corrected in place. ADR-2363's residual-gap section said the walk had 'no exclusions' — per docs/adr/README.md ('ADRs are append-only') that is corrected by a dated amendment rather than an in-place edit. Its D4 argument is unaffected: skill bodies are .md and stay bound. Fixes #3631 * fix(3631): narrow the digest exclusion after two isolated security reviews The first cut of this fix passed the full suite and was still wrong. Both orthogonal reviews rejected it, and the second one found a hole that has nothing to do with Python. HIGH — an excluded DIRECTORY was 'continue'd before recursion, so its whole subtree was permanently outside the digest. Declared hook script paths allow '_', '.' and '/' with no directory or extension rule, so hooks:[{script:'__pycache__/run.js'}] installed, executed via node, and its bytes could be rewritten forever without moving the hash. Ship benign v1, collect consent, then own the machine. No Python involved. FALSE RATIONALE — the justification I wrote into the code, CONTEXT.md, the ADR amendment and the changeset claimed CPython validates a cached .pyc against its sibling source, so the source staying hashed kept consent honest. That is not true, and I proved it by execution rather than argument: default timestamp invalidation compares only the source's mtime and size, both settable by anyone who can write the bundle. A forged pyc ran while the .py was byte-identical. Also wrong: '*.pyc' matched anywhere, but a legacy sourceless scripts/x.pyc IS importable, so excluding it was a live vector. Narrowed to what is actually defensible: - a DIRECTORY named __pycache__/.pytest_cache has only its TAG_DIR marker suppressed; the walk still recurses and hashes every non-excluded child. - .pyc/.pyo are excluded ONLY when the parent basename is exactly __pycache__. - a regular FILE named __pycache__, and a DIRECTORY named x.pyc, stay bound. - declared hook paths containing a __pycache__/.pytest_cache segment or a .pyc/.pyo basename are now rejected in both validator copies — a file named .pyc can contain perfectly valid JavaScript, so the exclusion must not be reachable from a declared surface. Accepted residual risk, stated plainly in ADR-2363 and CONTEXT.md instead of explained away: a forged __pycache__/mod.pyc matching an unmodified, still-hashed mod.py executes without moving the digest. Before this change that write was detected. It is accepted to stop routine bytecode caching from silently deactivating capabilities, and it is bounded — the attacker needs post-consent write access, everything outside __pycache__/*.pyc stays hashed, and no declared surface can point into the excluded space. Known limitation, not papered over: .pytest_cache CONTENTS still move the digest. Only the directory marker is suppressed. Excluding that subtree would reopen the HIGH finding. Refs #3631 * fix(3631): drop the .DS_Store exclusion and pin what the caps actually bind Second round of isolated review findings. The hardening closed the two original holes — both re-reviews confirmed that by execution — but it introduced a new one of the same shape, and left three claims unbacked. HIGH, self-inflicted: .DS_Store was excluded from the digest at any depth, but the hook path validator was hardened only for __pycache__/.pytest_cache/.pyc/.pyo. So script:'hooks/.DS_Store' was ACCEPTED, runnableHookCommand emits the bare quoted path for a non-.js name (the branch .sh hooks already use), and capability-source copies it with its mode bit intact. Ship it +x with a benign shebang, take consent, then rewrite it forever — the digest never moves. Fixed by DELETING the .DS_Store exclusion rather than teaching the validator about it: .DS_Store has nothing to do with this issue's Python bytecode symptom, and an excluded filename is a permanently unhashed name. The narrower the exclusion, the smaller the hole. The residual-risk bound in ADR-2363 and CONTEXT.md claimed declared surfaces cannot reach excluded space. That is false and is now stated correctly: node resolves an unregistered extension through the default .js handler, so a hashed, consent-covered hooks/run.js that requires '../__pycache__/mod.pyc' reaches it in one hop. The validator guard raises the bar for DECLARED surfaces; it does not contain the risk. The two bounds that are real — post-consent write access required, everything outside __pycache__/*.pyc still hashed — are kept. The BUNDLE_MAX_FILES boundary test had gone vacuous: it padded with root-level *.pyc, which the hardening made non-excluded, so it no longer proved anything about excluded entries while the ADR claimed the caps were test-pinned. It now pads __pycache__/f{i}.pyc, with the arithmetic re-derived by execution (capability.json + the still-counted __pycache__ dir + N). BUNDLE_MAX_TOTAL_BYTES had zero coverage at all and is now pinned by a sparse 32 MiB __pycache__/big.pyc that must still trip the size cap — the test that proves exclusion did not become an unbounded-bytes hole. Added the parity assertion CLAUDE.md's Generative Fix Divergence rule requires for the two isSafeHookScriptPath copies, and proved it can fail: mutating one BUILT copy to drop .pyo made the parity check report the divergence. Also pinned semantics that were correct but untested and would have survived mutation — __pycache__/sub/x.pyc stays hashed (the parent resets to sub, which is the recursion threading itself), .pytest_cache/y.pyc stays hashed, and .pyo in both directions, which was a free surviving mutant. Changeset rewritten: it still described the rejected wholesale-exclusion semantics.

Scope revised with maintainer approval and recorded on the issue: the epic's literal ask was a rule rejecting a bare-name spawn outside the seam. Surveyed at ac1b6d679, ~30 such sites exist and none is a defect — git, gh and npm ship native .exe that CreateProcess resolves unaided, and the rest are POSIX-only tools. ADR-1703 rules 2 and 3 forbid grandfathering and escape hatches, so a literal rule would be unsuppressable and would force rewriting 30 correct calls. The epic's actual thesis was four private RESOLVERS, not four bare spawns. So the rule flags re-implementing resolution: reading PATHEXT in any casing from any object, and a hardcoded list carrying two or more of .exe/.cmd/.bat/.com — precisely the shapes fallow-runner's candidateNames and gsd-tools' PATHEXT string had before Phases 1 and 2 deleted them. Three boundaries were arrived at rather than assumed: two-or-more a single .endsWith('.cmd') is a classification, not a candidate set; runtime-hooks-surface derives .cmd shim paths that way boundary-aware a naive substring test flags .execute and .compacting, caught on src/host-integration.cts before it could become a false positive nobody could suppress suffix-anchored the seam exemption matches src/shell-command-projection.cts exactly; a substring match would also exempt the dispatch test file. Case I9 pins it. PATH scans are deliberately NOT flagged — membership checks (bin/install.js) are indistinguishable from resolution scans, and an unsound rule in a zero-escape-hatch architecture is worse than no rule. To make the ratchet strict with no carve-out, resolveExecutableBinary gained pathOverride: search THIS PATH, read everything else including PATHEXT from the ambient environment. resolveFallowBinary now supplies its own search path without hand-threading PATHEXT, which would itself have been a private read. The three alternatives were all worse: exempting the file is grandfathering, exempting the AST shape is a carve-out every future caller must replicate, and dropping the pass-through would silently ignore a user's real PATHEXT — buying a lint rule with a correctness regression. eslint-rules/** is outside the rule's globs rather than exempted, because portability-vocab.cjs owns the extension set. scripts/**/*.cjs got its own block so that exclusion does not leave a hole in the ratchet. Started green with nothing suppressed. Proven able to fail: a fixture with both signals reports two errors. Refs #3411 * fix(#3619): close the PATHEXT destructuring evasion and correct two overclaims Adversarial review found a trivial evasion of the rule's primary signal: the visitor only handled MemberExpression, so const { PATHEXT } = process.env const { PATHEXT: exts } = process.env const { Pathext } = opts.env were all unflagged. That is a common idiom, not an exotic bypass. An ObjectPattern visitor now catches it in every form — renamed, any casing, any receiver, string keys — while leaving a computed key alone, since it is not statically decidable. I10-I13 pin the invalid forms and V9/V10 pin PATH and the computed key. Two overclaims corrected, both mine: Standards review proved the docs were factually wrong. Both the ADR amendment and the CONTEXT.md entry asserted that tests/shell-command-projection-dispatch.test.cjs is still linted by this rule. It is not — the rule's surface is src, gsd-core/bin, scripts and hooks, and tests/** is deliberately outside it because test setup legitimately assigns process.env.PATHEXT (fallow-runner's P3 does exactly that). The suffix-vs-substring distinction is therefore proven by RuleTester case I9 feeding a synthetic filename, NOT by real coverage of that file. Both documents now say so. The rule's own docstring claimed the seam exemption matches the seam path 'exactly'. It is a suffix match, so a nested foo/src/shell-command-projection.cts would also be exempt. Suffix matching is kept — it is how sibling rules resolve paths and the nested case does not exist — but the docstring now states the boundary rather than overstating the precision. The evasion fix was verified by executing eslint against both destructuring forms in scripts/, not by inspection. Probe: 31/31.
