Tom Boucher	1591454357	feat(#3409): reject shell guards that cannot observe their own failure arm (#3558) ... * test(#3409): failing-first regression tests for unreachable shell guard arms Drives the three live defects fail-first, executing the shipped workflow snippets rather than a re-typed copy: - G1/G2 plan-phase.md Walking Skeleton gate reads `--pick summaries_total`, a field that does not exist, so PRIOR_SUMMARIES is always "" and the gate has never fired (#3365). G2 is the load-bearing negative-space case: it rejects a fix that treats "no answer" as "zero" and fires unconditionally. - G3 plan-phase.md PHASE_REQ_IDS resolves "" instead of the TBD sentinel on a phase with zero requirements. - G4 complete-milestone.md's bare `cat <glob>` blocks on stdin under a nullglob left set by an earlier block (measured hang). Skipped on Windows for G4 only: the FIFO-blocked-stdin mechanism is POSIX only, and a weakened assertion there would pass vacuously. Refs #3409 * fix(#3409): make nine shell guards observe their own failure arm `--pick` coerces a missing field to empty string and exits 0, so the `|| echo <default>` fallback after it fires only on a verb typo, never on the field absence it was written for. Nine sites relied on that arm. - plan-phase.md walking-skeleton gate: `--pick summaries_total` names a field that does not exist under any flag combination, so the gate has never fired on any project (#3365). Repointed at the existing single owner, `phases.list --type summaries --pick count`, which returns a real integer in every case including a project with no `.planning` directory. No new counter is added: a second one would duplicate the ownership ADR-3180 Decision 1 forbids. The gate now fires only on a literal "0", so an unanswerable query fails safe instead of entering skeleton mode. - plan-phase.md phase_req_ids: now falls back to the documented TBD. - The remaining seven convert to an explicit empty test. - complete-milestone.md read all phase summaries through a bare `cat <glob>`; under a nullglob left set by an earlier block that is zero operands, so cat blocks on stdin. Guarded with the array shape the #3300 fix already established in review.md. Refs #3409 * fix(#3409): guard eleven more globs that defeat their own fallback arm The nullglob audit this issue asks for turned up the same class in files #3300 never touched. - Eight bare `cat <glob>` reads (transition, complete-milestone, planner x4, verifier, phase-researcher). With nullglob set that is zero operands, so cat reads stdin and blocks; measured rc=137 at 3s. - Three `ls <glob> || echo "<message>"` sites (session-report, review-backlog and its generated skill). nullglob makes ls succeed listing the cwd, so the message never prints and the user gets a directory listing instead. Guarded with `[ -e "${_ARR[0]}" ]` rather than `[ ${#_ARR[@]} -gt 0 ]`. The count form is correct only when nullglob is set, and six of these seven files never set it: without it the array holds the unmatched literal pattern, so the count is 1 and the guard passes wrongly. `-e` is correct in both worlds. review.md keeps its count guards — that block sets nullglob two lines above them. skills/gsd-review-backlog regenerated from commands/, never hand-edited. Refs #3409 * feat(#3409): add the unreachable-shell-guard drift lint A sibling of lint-planning-prompt-drift.cjs, consuming the shared scripts/lib/drift-scan.cjs rather than copying it, wired into lint:ci. Both detectors are one shape — a fallback arm defeated by a legitimate success-on-empty: - Detector A: `--pick` and `|| echo` on one line. `--pick` is the discriminator because "missing field renders empty at exit 0" is a documented CLI contract, not a heuristic. A rule keyed on gsd_run matched 111 lines, ~132 of them legitimate, and was rejected. - Detector B: `cat <glob>` in command position, and `ls <glob>` whose exit code feeds a real fallback or an if/while head. Informational `ls <glob>` whose stdout is consumed (97 sites) and `|| true` failure suppression (~15) are not guards and never fire. Shrink-only ratchet keyed on (file, trimmed text) with a per-pair count, POSIX-normalized unconditionally so Windows CI cannot report everything fresh and stale at once. Ships with a ZERO-entry baseline: every site it can find is fixed. Exemption is the per-line `# gsd-scan-ignore: #NNN` marker whose reason must name an issue or URL; a malformed reason reports a distinct error rather than silently exempting. No file allowlists. ADR-3409 records the invariant, the measurements behind both detectors, and why the upstream `--pick` contract fix belongs to #3473. Refs #3409 * fix(#3409): resolve review findings — typed surface, sanitized reports, tighter marker Standards axis (blocker): the guard's tests asserted on human-readable stdout/stderr and on free-form baseline-load prose, which CONTRIBUTING prohibits by name. Added the typed surface it prescribes instead of weakening the tests: a frozen REASON enum, a --json report mode, structured loadBaseline errors, and a test locking Object.keys(REASON) so a new reason stays three coordinated changes. Security axis: sanitizeForReport covered every violation field but not the baseline-load error path, which embeds raw JSON.stringify output -- that escapes nothing above 0x1f, so bidi and C1 controls reached CI logs unfiltered. Routed through the sanitizer at the output seam. Security axis: the scan-ignore marker accepted `#0` and a bare `http://`. Tightened to a positive issue number and a URL with a host. This diverges deliberately from the sibling in tests/commit-files-pathspec.test.cjs, whose looser form was copied verbatim; the header now records the divergence. Security axis: G4 built its FIFO with `mktemp -u`, reserving a name without creating it. Now created inside a `mktemp -d` directory. Spec axis: ADR-3409 claimed a ninth site landed after the issue was filed. git blame disproves it -- all nine predate it; the issue's hand count missed one. Corrected. The design and test matrix still specified B9 as a FLAG after implementation reversed it to PASS; both now record the reversal and why. Refs #3409 * docs(#3409): add the how-to for resolving unreachable-guard findings Reference and Explanation are carried by ADR-3409; this is the task-oriented quadrant CI cannot check for. The page exists mainly for one thing the lint structurally cannot catch: both `[ -e "${_ARR[0]}" ]` and `[ ${#_ARR[@]} -gt 0 ]` remove the glob from the command and therefore both pass, but the count form is correct only when nullglob is set — and nullglob is usually set in a different block of the same file. A reference table cannot carry that; a how-to can. Also documents the reason codes, so a reader can tell "nothing to report" from "could not look". No tutorial: this is a gate inside an existing CI loop, not a new entry point a newcomer starts from. Refs #3409 * fix(#3409): bring the touched prompt files back under their size gates The remote run was red on 14 tests, all size/attribution, none of them the regression suite. - agents/gsd-planner.md was 194 chars over a 49152 cap enforced by four separate tests, each of which says the remedy is extraction, not a bump. It had 41 chars of headroom before this branch. Its `## Checkpoint Types` section was an unlinked, condensed duplicate of references/checkpoints.md, which already carries all three types and their XML shapes; the section now points there and keeps the three names and percentages inline. Net -969, margin 1010. - gsd-core/workflows/execute-phase.md sat 2 chars under a comfortable margin assertion. Dropped the AUTO_MODE default: the `|| echo "false"` it replaced was unreachable, so the value was already sometimes empty on next, and its only consumer compares against `true`. Net -16. Left plan-phase.md's AUTO_CHAIN default alone -- that file names an explicit `false` branch, so empty would match neither branch. - Acknowledged the seven prompt files that genuinely grew, one specific reason each. Five of those paths were already claimed by spent fragments identical to next, which blocks a second source naming the same path; removed just the colliding key from each, deleting the two that this emptied. Refs #3409 * test(#3409): extract the whole PHASE_REQ_IDS block, not just its first line G3 failed on the remote runner with '' !== 'TBD'. The test was wrong, not the workflow. The shipped contract is now two consecutive lines -- the capture and the `${PHASE_REQ_IDS:-TBD}` default -- but the helper's `^PREFIX=.*$` regex returns only the first match, so the test executed half the contract and correctly observed the empty string. Renamed to extractAssignmentBlockFor and taught it to consume the contiguous run of lines sharing the prefix. The assertion is untouched: TBD is the right expectation, and weakening it to accept the empty string would have reinstated exactly the class this suite exists to catch -- a check that cannot observe the thing it is checking. extractFencedBashAfterAnchor is unaffected: it is fence-delimited rather than line-anchored, so G1/G2/G4 still capture their full blocks. Refs #3409 * chore(#3409): drop a spent ack fragment that collided on complete-milestone.md #3458 landed on next while this branch was in flight and its fragment claims complete-milestone.md, which this branch also grows. Two ack sources may never name the same path. Its entry is spent: the +9163 it explains is already absorbed at base, so it can no longer clear anything, and the checker's own guidance for spent entries is to delete them. Removing the key emptied the fragment, so the file goes too -- an empty one signals nothing. Refs #3409 * chore(#3409): backfill changeset pr number 3558 * test(#3409): hoist a regex subject out of exec() to clear the injection scan CI's prompt-injection scan flagged `MARKER_RE.exec('# gsd-scan-ignore: ...')`. The pattern `exec[[:space:]]*\(["']` is receiver-blind on purpose, so it catches `require('child_process').exec('...')` -- and the scanner's own header records that RegExp.prototype.exec is collateral, to be handled by its allowlist. Allowlisting the file would blind it to the real exec vector permanently, so the subject is hoisted into a const instead: same assertion, scanner left at full strength, no security surface widened.

sim	d1760e3c31	refactor(#3309): migrate cmdValidateHealth onto the rule table ... Replaces cmdValidateHealth's hand-rolled addIssue/switch accumulation (961 lines) with buildPlanningSnapshot -> evaluateRules -> map to the legacy {code, message, fix, repairable} shape, bucketed by severity. Two pre-checks (home-dir E010/I010, .planning/-root-missing E001) stay outside the rule table entirely, per ADR-3180 §8.2 rule 4 ("no precedence system") — building "some rules suppress others" into the table would itself be the forbidden precedence system. W024 (STATE.md commit-age freshness) also stays outside the table: its committed rule is a documented permanent no-op (readStateHeadFreshness's git-log shell-out is ambient I/O a Rule.check may never perform, and no PlanningSnapshot field carries a commits-behind count). Migrating onto the rule table as designed would have silently regressed 7 passing tests in tests/health-validation.test.cjs — found while wiring this function, kept as a real check in the wrapper instead (same I/O license applyRepairs already relies on), fixed inline per this repo's no-defer policy rather than accepted as a silent loss. Ports the real repair-handler bodies (createConfig/resetConfig, regenerateState, addNyquistKey/addAiIntegrationPhaseKey, backfillMilestones) into health-diagnostic.cts's applyRepairs, replacing the skeleton's stub. DESTRUCTIVE-risk remedies (resetConfig/regenerateState) are refused by --repair — a disclosed breaking change; repairable now means "an automatic repair will actually run," not merely "a remedy exists to describe," so E004/E005 now report repairable:false. --backfill alone now actually triggers backfillMilestones, fixing a latent bug where its gate was unreachable without --repair also being set (verify.cts:2504, confirmed dead code pre-migration). Test updates distinguish the two explicitly-authorized behavior changes (DESTRUCTIVE refusal, backfill-alone fix, W021->W026 split) from preservation — every changed assertion is commented with why, and new regression tests were added for both changes plus W021/W026 mutual independence. Drift-guard bookkeeping (bypass-baseline shrunk to the one disclosed W024 exception, milestone-window and phase-enumeration exemptions, test-file-count allowlist) updated for the relocated/new functions this migration introduces.	2026-08-13 02:28:49 -04:00
sim	2538fd6344	refactor(#3308): add planning-snapshot.cts parsed projection per ADR-3180 §8.1 ... Phase 10 of epic #3180. src/planning-snapshot.cts is a new parsed projection of .planning/, composed exclusively from the already- consolidated §7 owners (getMilestoneInfo, listMilestonePhaseDirs, isPhaseComplete, scanPhasePlans, stateFieldValue, planningPaths) plus the frozen SCOPE enum. No new semantic derivation is introduced beyond worstScope, a pure combinator folding several independently-scoped owner answers into one composite signal. Adds STATE_UNREADABLE to src/unusable-input.cts's UNUSABLE_REASON (seventh #1879 site) for STATE.md exists-but-unreadable, distinct from absent. Adds scripts/lint-planning-snapshot-bypass-drift.cjs, a ratcheted drift guard (ADR-3180 Decision 4(e)) scoped to DIAGNOSTIC_RULE_FUNCTIONS (currently cmdValidateHealth in src/verify.cts only) preventing new raw .planning/ reads from bypassing the snapshot, while acknowledging cmdValidateHealth's existing 15 raw-read sites as debt owned by Phase 11 (#3309). Six-gate .cts ripple: .gitignore, eslint.config.mjs, docs/INVENTORY.md + manifest regen, CONTEXT.md glossary entry. Breaking changes: none. This phase adds the subject only; Phase 11 migrates cmdValidateHealth onto it.	2026-08-12 21:43:39 -04:00
Tom Boucher	8b4545f3c0	feat(#3218): the prompt layer asks the CLI for plan counts (#3327) ... * feat(#3218): the prompt layer asks the CLI for plan counts Seven sites across four workflows counted plans with ls and wc -l instead of asking the CLI. A shell glob is not scanPhasePlans, so every fix that landed on the owner missed all seven: they counted superseded plans as live, reported zero for the nested plans layout, and missed loosely-named files. The 1762 figure of 30 plans and 24 summaries came from here. phase find is extended rather than a verb added - 3218 is an enhancement whose own checklist says it adds no new command, and CONTRIBUTING makes a new verb a feature needing approved-feature. It gains plan_count and summary_count for the live set and plan_count_all for the physical one, additively; the existing arrays are untouched. Both sets are exposed because the sites need different ones. Amendment 1 names two cases; three of these sites ask a third - did the planner write files to disk - and take the physical set, because a superseded plan is still a file the planner wrote. The progress.md dead route is fixed and was worse than the issue said. It read .plans and .summaries arrays that roadmap.analyze has never emitted, so the fallback always fired, both counts were always zero, and Route 0's resume-incomplete-phase check had never fired at all. The ratchet baseline is empty. Its own stale-entry check makes that self-enforcing. Verified on the remote runner. * test(#3218): acknowledge the workflow growth and update the stale guard The emitted-attribution gate named its own remedy, so it was followed rather than pre-guessed: four workflow files grew between 200 and 770 bytes because each replaced a shell glob with a find-phase call plus its jq extraction. plan-phase grew most - two sites, and it takes the physical count for its did-the-planner- write-files question. progress also carries the Route 0 dead-path fix. plan-phase-drift-guard asserted the literal old ls shape. Updated rather than deleted: what it protects is that a filesystem fallback exists and is reachable, and that is intact. It is not a regression - gsd_run is already load-bearing throughout plan-phase.md long before step 9, so the 9a and 11a fallback never existed to survive gsd_run being unavailable; it guards against the planner subagent's return hanging. Three ack sources collided with the new fragment, which the gate treats as a hard error rather than last-wins. Only the three colliding keys were removed, not the 421 spent entries, and two fragments left entryless were deleted per the convention that an empty fragment signals nothing. Verified on the remote runner. * docs(#3218): document the live and physical plan counts docs/CLI-TOOLS.md gains a find-phase counts section covering plan_count and summary_count for the live set against plan_count_all for the physical one, plus the null-not-zero not-found behavior. The live-versus-physical distinction is spelled out because a caller picking the wrong one gets a plausible number, which is the trap Amendment 1 records. Changeset leads with what a user sees: progress and execute-plan stop counting superseded plans as outstanding, a nested plans layout stops reporting zero, and Route 0 resume routing starts working after never having worked. No how-to. Nothing is enabled and nothing is sequenced - the user runs the same command and the number is simply correct. The one new distinction is field semantics, which is what a reference entry is for. * chore(#3218): backfill changeset PR number pr:0 placeholder replaced with the real number now that #3327 exists. --------- Co-authored-by: sim <sim@local>	2026-08-10 12:56:38 -04:00
Tom Boucher	b9f51836e6	refactor(#3180): ADR-3180 behavior contract + cross-surface drift guardrails (#3223) ... * refactor(#3180): one owner for completion ratio, a prompt-layer drift guard, and a written behavior contract The 2026-08-08 coverage audit on #3180 found the epic's copy counts were a lower bound for the third consecutive time, and that two derivation families had never been named at all. ADR-3180 gains Decision 7 — a normative behavior contract that says what the right answer IS for each derivation, not merely who owns it. A reviewer with no written rule can only ask "does this look like the others", which is how a fifth copy passes review. Decision 4 gains (d) scan surface is every authored surface and an owner FILE is never exempt, only its named functions; and (e) a surface that cannot be consolidated today ships ratcheted, never unguarded. Completion ratio: `clampPercent` sat exported and unused beside six hand-inlined copies of its own body across five modules. All six now route through it; `clampPercentFromFraction` is added for the one caller that already held a fraction. Every migration is behaviour-identical — clampPercent's first line IS the `total > 0 ? … : 0` ternary each copy carried. Guarded by lint-completion-ratio-drift.cjs, which reports zero re-derivations with no file-level exemption. Prompt layer: workflow markdown re-derives live-plan counting in raw shell (#1762), invisible to every `src/`-scoped guard. lint-planning-prompt-drift.cjs scans it with a shrink-only baseline of the 7 sites that exist today — new sites fail, and a baseline entry that stops firing fails too, so an acknowledgment can never outlive the thing it describes. lint-milestone-window-drift.cjs stops exempting its owner file wholesale; only the four named canonical functions are exempt now. The blanket exemption was pointed at the one file most likely to grow the next copy, and it had. Refs #3180 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs(#3180): link Phases 6-8 sub-issues (#3216, #3217, #3218) from ADR-3180 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3180): address orthogonal review — consumer-output identity tests, count-keyed ratchet, property coverage Five findings from the two orthogonal review passes, all fixed. Decision 4(c) breach: the completion-ratio identity test asserted at the OWNER, which is exactly the bypass that decision exists to close — a consumer can call clampPercent and then post-process locally, leaving both the lint and an owner-level test green. It now drives `roadmap analyze`, `query progress` and `stats` and asserts on their own output, over a fixture containing a `status: superseded` plan so a consumer that re-counted raw files would report 60 where the owner reports 75. Decision 4(e) breach: ratchet entries named the epic (#3180) rather than the issue that removes them. They name Phase 8 (#3218) now. The ratchet keyed on (file, text) alone, so plan-phase.md's two byte-identical sites were one indistinguishable key and migrating either would have left the guard green with the other alive. Entries carry an occurrence count; fewer than acknowledged fails as a partial migration, more fails as a new copy. Adds the missing MAX_REGEX_LITERAL_LEN boundary coverage the sibling guard's test already had, and the fast-check property tests CONTRIBUTING requires for clamp/budget-limit functions. Refs #3180 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: stop wrapping a nested double-spawn in a 15s wall-clock budget (bug #641 probes) `tests/ci-test-scope.test.cjs`'s `bug #641` block spawned `run-tests.cjs` under PROBE_TIMEOUT_MS=15000; that child then spawned a nested `node --test`. A fixed wall-clock budget around a double spawn, running inside a container that is concurrently executing the full ~31k-test suite, fails by construction under load. Confirmed against three full matrix runs. Every failure was shaped `null !== 0` — the child was KILLED, never an assertion about the thing under test. One captured probe had already printed the correct resolution (`suite="all" files=2: a.test.cjs b.test.cjs`) and was killed anyway. It reproduces on `next` alone: 5 failures on linux-node22, 0 on linux-node24. The victim subset varies by run and by lane. What these tests are actually about is suite-token RESOLUTION — `unit` as a bare token in --files/--files-from. Executing the seeded trivial files is incidental and is the entire timeout surface, so the assertions move in-process against the same functions `main()` calls, in the same order. `parseArgs`, `selectExplicitFiles`, `selectFiles` and `walkTestFiles` are exported for that; no behavior, signature or logic changed. No coverage lost: `tests/run-tests-harness.test.cjs` already spawns the harness for real and asserts exit codes end to end, on a 120s budget. Pre-existing on `next`, fixed here rather than deferred. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: delete the three elapsed-time assertions CLAUDE.md forbids asserting on wall-clock time. Three assertions did, and all three are load-sensitive: on a saturated bench each can fail while the code under test is correct. In every case the load-bearing assertion sits on the line above and the timing line adds no discrimination. run-with-timeout: the stated worry — "was this 124 the cap firing or the 30s harness backstop?" — is already answered by the assertion above it. A backstop kills by signal, which surfaces as status null, never 124. Observed directly this session: three matrix runs produced exactly that null shape from killed children. normalize-test-command and context-predicates: both bounded a ReDoS check. A threshold only ever separates "fast" from "slightly slow", which is bench load, not correctness — catastrophic backtracking on 800 KB of input does not take 251ms, it does not finish at all. A real regression therefore shows up as the suite being killed on that test, which is louder and more reliable than a number. The structural assertions (returned unchanged; cleanly rejected) are what actually carry those tests, and they stay. The sweep now reports zero elapsed-time assertions in tests/. The remaining Date.now() uses are unique-path suffixes, barrier deadlines, fixture timestamps and fake mtimes — none of them assertions. Pre-existing on `next`, fixed here rather than deferred. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3180): backfill changeset PR number (#3223) Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3180): key the prompt-drift ratchet on POSIX paths so it works on Windows The baseline keys on (file, trimmed text). `file` came from scanTree's `path.relative()`, which uses NATIVE separators, while the committed baseline stores POSIX. On Windows every violation was therefore unmatched — reported as FRESH — and every baseline entry matched nothing — reported as STALE. The guard failed 100% of the time there, on both CI shards: ✖ scanRepo(repoRoot) matches the baseline exactly: zero fresh AND zero stale + { file: 'gsd-core\\workflows\\execute-plan.md', ... } The remote runner this repo gates on is Linux-only and cannot see this class at all; the GitHub Actions Windows lane is what caught it. Normalization is unconditional — never gated on process.platform. A platform-conditional normalizer makes the POSIX path the special case and leaves the Windows branch unexercised on every other OS, which is the same blind spot in a different place. It is applied at one seam inside findPromptDrift, which builds `file` on every returned violation, so the baseline key, the --update writer, the stderr report and the tests all consume one normalized value. The regression tests drive a Windows-shaped relPath directly and run on every OS rather than skipping off-Windows — a test that only runs on the platform where the bug lives is why this escaped. They include a sanity check that un-normalized input does NOT match, so the assertion cannot pass vacuously. Audited the three sibling guards: none keys against a committed cross-platform baseline, and their exemption keys are path.join-built, so producer and consumer share the native convention. Left correct code alone rather than making them look alike. scripts/lib/drift-scan.cjs is untouched — normalizing there would break those three on Windows.
