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.

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.

Tom Boucher	342590c70e	refactor(#3184): milestone windowing has one owner and a decidable failure signal (#3209) ... * test(#3184): failing-first milestone-window single-owner suite Covers the 50 input classes in the phase test matrix: scope classification (genuinely-empty vs truncated vs unscoped vs unreadable), the section-end owner's level boundaries, consumer-output identity per ADR-3180 Decision 4(c), the milestone.complete refusal with negative proof that no directory moved, the version-token boundary defect, drift-guard behavior, and three fast-check properties over document-shaped generators. Committed alone so the remote runner records the failure before the fix lands. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015kfkRFNUESoBspUYcAQaT3 * refactor(#3184): milestone windowing routes through one owner Three copies of the milestone section-end walk lived in roadmap-parser.cts — two distinct computeSectionEnd function nodes plus an inline third in getMilestonePhaseFilter's versionOverride branch. computeMilestoneSectionEnd is now the sole owner and the other two are deleted, not kept in sync by comment. The whole-repo drift guard found what the epic did not: state.cts held three more re-derivations of the same vocabulary — two byte-identical milestone bounding checks carrying a defect neither reported copy has (no boundary after the version token, so v2.0 matched inside v2.0.1), and a milestone-sectioning predicate. All three route through the owner now. A composition-level duplicate appeared inside this change's own first pass: getMilestonePhaseFilter and cmdMilestoneComplete each re-assembled a window out of the owner's primitives, and had already diverged on whether to skip a closed milestone heading. sliceMilestoneWindow is the one composition. Windows now carry the ADR-3180 SCOPE discriminator, so a truncated window is distinguishable from a genuinely empty milestone — those were output-identical, which is the whole failure class. roadmap analyze emits it (#3165), and milestone complete refuses to archive on anything but COMPLETE rather than pass-all moving every phase directory on disk (#3166). The pass-all degrade is preserved where its premise holds: making the filter deny-all would trade a silent over-inclusive answer for a silent under-inclusive one on the read paths that count with it. extractCurrentMilestone keeps its signature — 200+ affected symbols across 41 files and 25 process flows — and is a one-line wrapper over the scoped owner.

The blocker: hasPhaseEntries matched ATX phase headings fence-aware via tokenizeHeadings but tested the #2199 bullet form against un-stripped markdown, so a fenced EXAMPLE of the bullet syntax counted as a real phase. A genuinely empty milestone then classified TRUNCATED and milestone complete refused a legitimate archive — a false positive in the destructive direction, worse than the defect this phase set out to fix. Both that path and getMilestonePhaseFilter own pre-existing bullet scan now run on stripFencedCode, since leaving one meant the owner file gave two different answers to the same question. The selection rule — locate, prefer the non-closed heading, else the first — had been written three more times inside the file whose thesis is single ownership. selectMilestoneHeading owns it; all three sites route through it. The copies were behaviorally identical, so this is de-duplication with no observable change, verified by probing that all three paths select the same heading. roadmap analyze emitting a scope no consumer read left #3165's actual symptom alive, so Route 0 in next.md now treats a non-complete scope as scan-failed rather than as a clean empty scan, and the ADR amendment no longer overstates what shipped. Also: the scope refusal moved above the archive-directory create, so a refusal leaves nothing on disk; the versionOverride comment names all four consumers; COMMANDS.md documents the new guard beside its sibling.

CHANGELOG.md ships into that tree, and its #2658 entry quotes both malformed paths while describing the fix that removed them — so the release note documenting the fix trips the fix's own regression test. Red on next before this branch. The installer is correct: a probe over a real --trae --local install found 621 emitted files, exactly one hit, and it was gsd-core/CHANGELOG.md. The scan scope was the defect, not the product. Excluded by exact relative path rather than by loosening the patterns or skipping all markdown — the emitted agent and command markdown is precisely what #2658 was about, so the gate stays strong everywhere it matters.

Regenerated via npm run gen:install-tree; the delta is exactly that one path per fixture. The two drift guards themselves do not ship (scripts/lint-*.cjs is excluded), so only the extracted library moves. This matches the existing scripts/lib/allowlist-ratchet.cjs precedent, which is likewise a lint-only helper carried in the shipped tree. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015kfkRFNUESoBspUYcAQaT3 * fix(#3184): restore the #730 sub-milestone boundary and narrow the refusal The remote runner caught two regressions this branch introduced. Both were mine, and neither review pass found them — only running the existing suite did. The version-token boundary. I replaced locateMilestoneHeadings' \b with (?![\w.-]), reasoning that v2.0 matching inside v2.0.1 was the same defect #2562 fixed in isMilestoneShippedInRoadmap. It is not the same question. A milestone state of v8.0 legitimately selects the '## v8.0-B' sub-milestone section over a closed v8.0-A sibling (#730), and \b is what allows it while the stricter boundary forbids it — nine tests in roadmap-phase-fallback said so. Reverted to \b; the state.cts consolidation is now a straight merge with no behavior change, and the v2.0/v2.0.1 ambiguity is left exactly as it was. The ADR amendment and the design doc no longer claim otherwise. The refusal scope. I refused whenever the window was not COMPLETE, but #3166 is about the TRUNCATED window specifically — the heading is found and the section closes before the phase region, so pass-all archives everything. UNREADABLE and UNSCOPED are pre-existing, legitimately handled states, and refusing on them broke 'handles missing ROADMAP.md gracefully' and three archive tests. Narrowed to TRUNCATED; docs corrected to match. One of the new tests was also wrong: its fixture gave the shipped and current milestones' phases the same numeric id, and the filter matches on that id, so it could not have distinguished the two windows. Fixture corrected to exercise what it claims to.

The extracted drift-scan.cjs was copied in and never enumerated, so it outlived uninstall, left the directory non-empty, and the rmdir that follows failed. Added to GSD_SCRIPTS_LIB_FILES, following allowlist-ratchet.cjs, which is likewise a lint-only helper that ships there and is enumerated. Verified with a real install-then-uninstall into a temp target: scripts/lib/ held exactly the three GSD files and was gone afterwards. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015kfkRFNUESoBspUYcAQaT3 * test(#3184): assert install and uninstall agree on scripts/lib and scripts/changeset Found while shipping this phase, and fixed here rather than noted. install() copies scripts/lib/ and scripts/changeset/ into the target WHOLESALE — the comment at the copy site literally says "and any future lib helpers". uninstall() removes them by hardcoded enumeration, deliberately, so a user's own helpers in those directories survive. A wholesale writer paired with an enumerated remover cannot stay in sync by construction: any file added to either directory ships to every user and is then orphaned in their repo forever, since it survives uninstall, leaves the directory non-empty, and the rmdir that follows fails. Nothing reported this. 31,225 tests were green over it. That is the same divergence class this epic exists to delete, sitting in the installer, so it gets the same remedy CLAUDE.md prescribes for it: a parity assertion that fails the moment the two surfaces disagree. The test compares each directory's real contents against its enumeration and names the offending file plus the constant to add it to. Both enumerations are hoisted to module scope and exported, so the test asserts on the actual arrays rather than pattern-matching the installer's source — no allow-test-rule annotation needed. Proven non-vacuous both ways: empty diff on the current tree, correct report when an unenumerated file is injected. scripts/changeset/ turned out to carry the identical defect and is covered too.
