Tom Boucher	2f86278b5e	fix(#3003): opt-in mechanism for intentional deletions in worktree.cleanup-wave (#3757) ... * test(#3003): failing-first suite for declared deletions in cleanup-wave Binds the guard's opt-in before it exists, so the suite is RED against next. The rows that carry the weight are the over-authorization set: a directory declaration must not authorize its children, a glob declaration must authorize nothing, and a declaration must not act as a string prefix of another path. Each of those BLOCKS, and each would PASS under a prefix, glob, or startsWith matcher — which is how a path list quietly degrades into the boolean opt-in #3003 explicitly rejected. The glob row matters most: declaredScopePrefix already returns null ("matches everything") for a glob-leading pattern, correct for the advisory it serves and catastrophic for a gate. Also pinned: a failed deletion check blocks on its own reason rather than being filtered into a pass; the block detail names only the undeclared residue so the operator is not misdirected by paths that were fine; an entry with no declaration blocks exactly as before; junk and non-array declarations do not authorize; and a blocked entry still isolates rather than aborting the wave (#2852, which must stay fixed). Two advisory rows cover an interaction found while designing: git diff --name-only includes deleted paths, so without unioning the declaration into the #2596 scope check, authorizing a deletion would raise SCOPE_OUT_OF_DECLARED against the very path just authorized. A seeded property states the whole invariant the three over-authorization rows sample: a deletion merges iff its normalized path is in the declared set. * feat(#3003): declared deletions opt-in for the cleanup-wave guard The deletions guard blocked the merge-back of any executor branch whose diff removed a file, with no way to say a removal was intended. A plan that folded one test file into a sibling could not be merged by the tool meant to merge it, forcing a manual --no-ff outside the tool -- strictly less safe than what the guard protects against. A plan now declares removals in its own frontmatter (files_deleted), and that list rides the same path files_modified already travels: plan-document parse -> phase plan JSON -> the per-plan worktree gate -> record-agent/create --deletions -> declared_deletions on the manifest entry -> the guard. The guard blocks only the deletions NOT in that list. A path list rather than a boolean, per the pinned decision: a boolean disarms the guard for the whole entry, so an unexpected deletion riding along with a declared one would pass unnoticed. Matching is exact after the module's shared normalizer -- never a prefix, never a glob. Both would let one declaration authorize a whole set, which is the mass-deletion accident the guard exists to catch. That also means declaredScopePrefix is deliberately NOT reused here: it returns null ("matches everything") for a glob-leading pattern, which is right for the advisory it serves and would silently disarm a gate. The block detail now carries only the undeclared residue, so an operator is not sent looking at paths that were fine. A failed deletion check still blocks on its own reason and is never filtered into a pass. A blocked entry still isolates rather than aborting the wave (#2852). The #2596 scope advisory unions the declaration into its declared set -- git diff --name-only includes deleted paths, so without that, authorizing a deletion would immediately warn that the same path was out of declared scope. Optional and additive throughout: files_deleted is absent from PLAN_REQUIRED_FIELDS, a manifest entry without declared_deletions keeps the original unconditional block, and omitting --deletions leaves the on-disk entry shape untouched. Supersedes the spent #2856 emitted-drift ack entry for execute-phase.md, the same supersede that entry performed on #3370 and #3370 on #3324. * fix(#3003): wire --deletions on every dispatch surface, not just one Review found the feature inert on two of three dispatch paths. execute-phase.md (harness inline) passed --deletions, but the orchestrator-worktree path (executor-isolation-dispatch.md, worktree.create) and the Fleet-parallel batch path (capabilities/claude-orchestration/fragments/execute-wave-pre.md, worktree.record-agent) still passed only --files. A plan declaring files_deleted would have merged on one path and been blocked on the other two -- the exact bug #3003 exists to fix, left unfixed where most of the isolation actually runs. Worse, per-plan-worktree-gate.md already claimed --deletions was passed 'on the same worktree.record-agent / worktree.create calls', which was false for both untouched sites. A doc asserting coverage that does not exist is how a gap survives review. All four surfaces now pass the flag, verified by sweeping every .md under gsd-core/, capabilities/, commands/, skills/ and agents/ that invokes worktree.record-agent or worktree.create: each one that passes --files now also passes --deletions. The isolation-dispatch note explains why this flag, unlike --files, is not advisory -- omitting it does not skip a check, it blocks a merge the plan declared. Regenerates capability-registry.cjs, which the fragment edit made stale. Neither newly-grown file needs an emitted-drift ack: executor-isolation-dispatch.md sits under workflows/execute-phase/steps/ and execute-wave-pre.md under capabilities/, both outside currentSizes()'s non-recursive scan of gsd-core/workflows/ and agents/. * docs(#3003): document files_deleted where a plan author will actually find it The feature's entire user surface is one plan-frontmatter field, and the canonical reference for that frontmatter -- docs/reference/plan-md.md, the table that documents every other key -- never mentioned it. A field nobody can discover ships as a field nobody uses. Adds the files_deleted row and an example entry in all five locales (en, ja-JP, zh-CN, ko-KR, pt-BR), stating the property that makes the opt-in safe: matching is exact per path after separator normalization, with no globs and no directory prefixes, so a declaration can never authorize more than it literally lists, and omitting the field keeps the guard's original unconditional block. Also corrects two claims in the scope-conformance how-to that this change made false. Its opening paragraph described the recorded declared scope as files_modified alone; declared_deletions is now unioned into that comparison. Its "Renames are not detected specially" bullet asserted the deletions guard blocks any entry whose diff contains a deletion, full stop -- which was the whole point of #3003 and is no longer true. Reworked to say what now decides a rename's fate: declare the old path in files_deleted and both halves become ordinary paths for the advisory check, which is also why the old path needs no separate files_modified entry. Documentation that describes the pre-change behavior of the thing being changed is worse than no documentation, because a reader trusts it. * fix(#3003): close every review finding on the declared-deletions opt-in Two independent isolated reviewers, correctness and security. Neither found a blocker; both found real defects, and the directive treats a finding at any severity as blocking. All of them are fixed here. MAJOR -- the submodule worktree gate could not see a deletion-only plan. per-plan-worktree-gate.md intersected $SUBMODULE_PATHS against $PLAN_FILES alone, while $PLAN_DELETIONS was extracted and then never used. Before files_deleted existed, a path had to appear in files_modified to be planned at all, so the gate saw it; the new field plus the new docs telling authors a deleted path needs no files_modified entry opened a hole where a plan whose only submodule touch is a removal kept worktree isolation on -- the exact case #2772 disabled it for. Both channels now feed the intersection. Note the posture is deliberately the OPPOSITE of the cleanup-wave guard: there the channels stay apart because a deletion AUTHORIZATION must never be inferred; here they merge because a safety fallback must never MISS a touch. MAJOR -- same-wave conflict detection could not see a deletion. The planner's implicit-dependency rule compared files_modified only, so plan A editing src/x.ts and plan B declaring files_deleted: [src/x.ts] scored as conflict-free and ran in parallel: one branch removing what the other is writing, which is the sharpest conflict there is. Overlap is now computed across both channels. MINOR (both reviewers, one root cause) -- the advisory union gave one field two matching rules. declared_deletions was unioned into the scope list handed to planWaveScopeConformance, which reads it with prefix-and-glob semantics. So a field that is exact-match-only at the gate silently became wider at the advisory: ["*.md"], inert at the gate, yielded a null prefix meaning "matches everything" and muted the advisory completely, and ["src"] muted all of src/. The union also activated the advisory on plans that declared no modification scope at all, warning on every modified path. Replaced with subtraction from the findings, gated on files_modified alone. One field, one rule, everywhere. MINOR -- core.quotepath made the feature silently inert for non-ASCII paths. git emits "tests/\303\251.ts" C-escaped and quoted, which never equals the declared plain path, so a correctly declared deletion of tests/é.ts would block forever with nothing pointing at the encoding. Both diffs now pass -c core.quotepath=false. NIT -- flag() consumed a following flag as a value, so --deletions --files x swallowed --files and dropped both. Now treated as a missing declaration, which fails closed. Fixed at both call sites; the helper is duplicated verbatim in cmdWorktreeRecordAgent and cmdWorktreeCreate and leaving one would reintroduce it. TEST -- one test passed for the wrong reason. "a declared deletion is in scope for the advisory" asserted only that warnings omit the deleted path; under a full revert the entry blocks first, warnings come back empty, and the negative assertion passes anyway. It now asserts the entry actually merged, which is the load-bearing half. Four regressions added, one per fix above. Docs corrected rather than extended. The rename bullet in the scope-conformance how-to claimed a rename whose delete side is undeclared never reaches the advisory. Verified false: git's rename detection is on by default, so a pure rename is a single R entry that appears in no --diff-filter=D output and was never gated, before or after #3003. Only a rename that edits enough to fall below the similarity threshold decomposes into add+delete. The pre-existing sentence made the same wrong claim; this restates it correctly instead of sharpening the error. The localized plan-md.md reference edits are reverted: the PR template requires docs content added here to be English, and the translations already lag by three fields, so English-only is the repo's standing posture, not an oversight. Agent-file size caps respected: gsd-planner.md is XL-tier by bytes but carries a separate 49152-LF-CHAR cap asserted by four suites, so its edit is deliberately terse and lands at 49141 with 11 chars of headroom, with the rationale moved to docs/reference/plan-md.md, which has no cap. gsd-plan-checker.md lands at 49107 bytes, 45 under the LARGE cap. Both acks merged into the existing fragments that already name those paths, since two ack sources may never name the same path. * fix(#3003): decode git's path quoting instead of changing the git argv The previous commit's non-ASCII fix turned the remote suite red: 44 failures, 42 of them "unexpected git call: -c core.quotepath=false diff --diff-filter=D --name-only ...". The suite's git mocks match on exact argv, so adding two flags to the deletions diff and the advisory diff invalidated every existing fixture in tests/worktree-safety.test.cjs. Rewriting dozens of fixtures to accommodate one flag would be paying a large Hyrum's-law bill to fix a small defect. Both execGit calls are reverted to their original argv. The C-quoting is now decoded in normalizeScopePath instead, via a new decodeGitQuotedPath helper. That is the better fix on its own merits, not merely the cheaper one: the git argv is untouched so no fixture moves, the decode lands on the ONE normalizer already applied to both sides of the comparison so the declared and reported paths cannot disagree, and it holds regardless of the user's own core.quotepath setting rather than only when we remember to override it. A value not wrapped in a leading AND trailing quote is returned completely untouched, so the plain-ASCII path -- the overwhelmingly common case -- is byte-identical to before. Escapes decode to BYTES collected into a Buffer and UTF-8 decoded only at the end, because \303\251 is two bytes forming one character and decoding them separately yields mojibake. Malformed input never throws: a trailing lone backslash or a short octal escape degrades to the literal character, since one bad path must not take down a cleanup wave. Caught while reviewing the helper: the non-escape branch pushed a UTF-16 code unit rather than UTF-8 bytes. Git always escapes non-ASCII so its own output was fine, but this normalizer runs on the DECLARED side too, and an author may write a quoted path holding a literal é -- pushing 0xE9 alone is invalid UTF-8, so the declaration would decode to a replacement character and silently stop matching. That is precisely the failure this change removes, reintroduced on the other side of the comparison. Now converts whole code points, surrogate pairs intact. The other 2 failures: tests/parallel-dependent-plans.test.cjs pins the exact unbackticked substring "files_modified overlap" in gsd-planner.md, and rewording that comment to "declared-scope overlap" deleted it. The comment is restored verbatim and the files_deleted change rides in the pseudocode and the Rule sentence instead. Recorded in the ack fragment so the next contributor does not rediscover it the same way. Four regression tests cover the decode through the public cleanup-wave seam (the helper is module-private): a declared non-ASCII deletion merges against a C-quoted git report, the symmetric case where the DECLARATION is the quoted form, an undeclared non-ASCII deletion still blocks with the residue naming the decoded path an operator can act on, and a path merely containing a quote is left alone. Plain ASCII was already covered and is not duplicated. * fix(#3003): revert the leading-dash flag guard, the review nit was wrong The remote suite came back with 2 failures, down from 44, and both point at the same thing: tests/worktree-safety.test.cjs:7045 already pins the opposite contract, deliberately. test('a flag-shaped --files value is not re-parsed as a flag', ...) recordAgent(['--files', '--branch']) -> files_modified === ['--branch'] -> branch === 'worktree-agent-a1' ("the real --branch value must be untouched") So consuming the next argv element positionally, whatever its shape, is the tested intent of this parser, not an oversight. The security reviewer's nit claimed --deletions --files x would "swallow --files and drop both". It does not: each flag runs its own indexOf, so --deletions records the literal '--files' while --files independently still resolves to x. And that literal is a path git never reports as deleted, so it authorizes nothing -- already fail-closed with no guard at all. The guard bought no safety and silently changed --files behavior along the way, outside this issue's scope. Reverted at both call sites, which are byte-identical again, along with the test asserting the reverted behavior and the docs sentence describing it. The nit is recorded as REJECTED in the review artifact with the reasoning above, rather than as fixed -- a finding that turns out to be wrong should leave a trace of why, or the next reviewer files it again. docs/CLI-TOOLS.md now states the positional-read behavior plainly instead, so the next person meets it as documented intent rather than rediscovering it through a red suite. * chore(#3003): backfill changeset pr number to 3757 * test(#3003): cover parsePlanDocument's filesDeleted branch to clear the mutation gate CI's Stryker shard for plan-document failed at 73.28 against a break threshold of 75: 170 killed, 62 survived, 232 total. Eight of those survivors are the filesDeleted block this issue added to parsePlanDocument, which shipped with no direct coverage at all -- the field was exercised end to end through the cleanup-wave tests, but the parser itself was never called with a plan that declares it, so every mutant in the block lived. Four tests, each pinned to specific mutants rather than written for coverage percentage: - absent key yields exactly [] -- kills the array-literal seed (["Stryker was here"]) and the `fmDeleted = true` conditional, which would otherwise produce ["true"] - a scalar underscore `files_deleted:` wraps into a one-element array -- kills `fmDeleted = false`, the `&&` logical-operator swap, the `fm[""]` string mutation on the first operand, the emptied if-block, and the ternary's non-array branch - an array-valued hyphenated `files-deleted:` maps element-wise -- kills the `fm[""]` mutation on the SECOND operand (only reachable when the legacy hyphen alias is the one carrying the value) and the ternary's array branch - an empty list yields [] -- boundary case, and a genuinely distinct one from the absent key: [] is truthy in JS so it ENTERS the if, and only Array.isArray's true branch mapping over nothing produces the same [] Threshold arithmetic: 174 of 232 are needed for 75%, and these take it to about 178, so the shard clears with margin rather than landing on the line. Every expected value was confirmed by executing the built parser before being asserted, not inferred from reading the source. --------- Co-authored-by: sim <sim@local>	2026-08-22 13:17:51 -04:00
Tom Boucher	a5706bd39d	enhance(#2596): validate a wave branch's committed diff stays in its declared scope (#3264) ... * test(#2596): failing-first suite for worktree-wave scope conformance Binds the advisory diff-vs-declared-scope check to behavior before it exists: the pure coverage predicate, the SUMMARY-artifact exemption and its parity with the rescue walker, the gauntlet integration (never flips ok, degrades on a git failure, survives a later block), the manifest normalizer's files_modified handling, and the --files negative-input matrix on record-agent/create. Refs #2596 * enhance(#2596): warn when a wave branch commits outside its declared scope The worktree-wave merge gauntlet validated branch, base, deletions, SUMMARY rescue and a clean worktree, but never compared a plan branch's actual committed diff against the files_modified the plan declared — so an executor that committed outside its brief merged into shared phase state silently. Adds an advisory scope-conformance check: when the manifest entry carries a declared scope, the gauntlet diffs HEAD...<branch> and appends one structured warning per path outside it. It never flips ok and never blocks the merge; promotion to a hard gate is a separate, disclosed change. With no declared scope no git subprocess is spent at all. Refs #2596 * docs(#2596): document the advisory worktree-wave scope-conformance check Records the optional --files flag on worktree record-agent/create, the advisory warnings channel cleanup-wave now emits, and its two deliberate noise limits (SUMMARY-artifact exemption, literal-prefix glob matching). Wires execute-phase to pass the plan's already-parsed PLAN_FILES. Refs #2596 * fix(#2596): close review findings on the scope-conformance advisory - share one path normalizer between the SUMMARY-artifact predicate and the scope comparison so the exemption and the check cannot drift - wire --files into the orchestrator-worktree dispatch, which created a worktree but never declared its scope, so the advisory silently did not apply on that backend; ADR-1239 requires both adapters share one check - correct the now-false blockquote claiming the check does not exist yet - add the fast-check property tests the repo requires for parser logic - add the record-agent/create parity test that Generative Fix Divergence requires for two surfaces implementing one rule Refs #2596 * fix(#2596): keep execute-phase.md under the frozen pre-phase-6 byte ceiling The one-sentence note added with the --files flag pushed execute-phase.md to 93708 bytes, past the ADR-857 PRE_PHASE6 cap of 93600 — the tightest of the three workflow size gates, and a hard cap an acknowledgment cannot clear. It failed three tests plus the differential attribution check. Condense the note to a one-line pointer (93543, 57 B of headroom); the full explanation already lives in docs/CLI-TOOLS.md and the dispatch step. The flag itself stays in the command, because the orchestrator reads this workflow at runtime and cannot pick it up from docs/. Acknowledge the remaining 143 B of growth by appending to the existing execute-phase.md fragment rather than adding a second one — the ack lint rejects two sources naming the same path. Refs #2596 * fix(#2596): make the execute-phase.md edit net-negative, not merely under the cap The size gate on this file is two assertions, not one: bytes < 93600 AND bytes <= 93400. The base is exactly 93400, so the file is at its budget and any growth trips the margin assertion — the previous fix cleared the ceiling but not that. Move the --files explanation to per-plan-worktree-gate.md, which already owns PLAN_FILES and carries no cap, and reclaim the rest from two clauses in the sentence being edited: the cleanup-wave rules phrasing, and a 'non-zero exit' the very next sentence already states. execute-phase.md ends at 93392, eight bytes below base. The flag itself stays in the command — the orchestrator reads this workflow at runtime and cannot pick it up from docs/. With no growth left, the acknowledgment is unnecessary and its byte delta was no longer true, so the shared ack fragment is restored byte-identical to base. Refs #2596 * docs(#2596): add the how-to for interpreting scope-conformance warnings The docs for this change were entirely Reference — the flag and the warning codes — with the task-oriented quadrant empty. Adds the page that answers the question an operator actually has when the advisory fires: what the two codes mean, that nothing is blocked so there is no failure to hunt for, how to tell whether the executor over-reached or the plan under-declared, and the three ways the check legitimately stays silent so an absence of warnings is not mistaken for proof of conformance.

Four independent copies of the agent branch allow-list regex (^(worktree-)?agent-...) never learned this namespace: - hooks/gsd-worktree-path-guard.js:176 — FAILED OPEN (process.exit(0)), silently disabling path containment for exactly the concurrent dispatch mode where cross-worktree writes are most likely - src/worktree-safety.cts:21 — silently dropped cleanup-wave manifest entries - agents/gsd-executor.md:503 — FATAL halt on branch check - gsd-core/references/worktree-branch-check.md:33 — same FATAL halt Extended all four to ^((worktree-)?agent-|worktree-wf_)[A-Za-z0-9._/-]+$.

sim	1e844b942c	fix(#3103): only "no such process" means the owner is dead ... Review found the previous commit fixed the wrong cliff. process.kill accepts a pid up to 2147483647 and throws a TypeError above it, so 2147483648 — an ordinary finite number — sailed past the finite check, threw, and was classified dead. Measured here: 2147483646 and 2147483647 raise ESRCH, 2147483648 and above raise ERR_INVALID_ARG_TYPE. The digit-length boundary the last commit pinned was a different, earlier gate, and its tests implied it was the meaningful one. The liveness helper now treats only ESRCH as dead. EPERM, a type error from an out-of-range pid, an error with no code at all — every outcome it does not recognise returns alive, because the value feeds a forced worktree removal and an unrecognised failure must never read as permission to delete. Against a build with the old catch, a lock holding 2147483648 reaps the worktree; with this one it is skipped and the directory survives. The finite check stays. It no longer carries the safety, but it still names garbage input accurately rather than reporting it as a live owner, and its comment now says that so it is not removed as redundant. The freshness verdict is split. An unreadable lock mtime and a genuinely recent lock both reported lock_too_fresh, which tells an operator to wait when waiting cannot help — the same conflation this module already separated for parse failures. The unreadable case is now lock_age_unknown. Only this module and its tests read these strings; no workflow or command consumes them. The dependency spread in the prune path is kept as it is, with a test that kills it. A caller-supplied porcelain parser displacing the default is the intended seam, not an accident: the parser is a declared member of the dependency type and the planner already prefers an injected one, so the hard-coded key restates the same default rather than guarding against override. Previously nothing exercised that line at all. Refs #3057 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-06 01:26:15 -04:00
sim	573d39ea60	fix(#3103): refuse to reap on a PID the parse could not represent ... A lock file whose PID is a digit string longer than 308 characters parses to Infinity, not NaN. The default liveness helper then calls process.kill with it, which throws a TypeError rather than an errno error, and that helper's catch only recognises EPERM — so it returns false, meaning "the owner is dead", and the worktree becomes eligible to be removed. The reaper already fails closed for this exact situation. It wraps the liveness call in a catch that sets alive and does not reap, with a comment saying liveness could not be determined. That protection never fires here, because the inner catch swallowed the error first and answered confidently instead of admitting it did not know. A guard that cannot verify safety reporting success is the defect this whole epic is named for, and it was sitting inside the one function in the tree that deletes things. The guard deleted earlier on this branch tested for NaN. That test really was dead — a digits-only capture cannot parseInt to NaN — but the reachable failure is non-finite, so removing it without correcting the predicate left the hole open. The check is now for a finite value, and a malformed PID reports the same lock_owner_unknown skip as an unparseable one, since both mean the same thing: the owner is unknown, so nothing is removed. Measured, not assumed: 308 nines still parse finite, 309 are Infinity. All three of that boundary are covered, along with a 400-digit case that asserts the worktree is still on disk afterwards — the consequence, not just the verdict. Against a build with the guard removed, that case reports pid_dead_and_merged and the worktree is gone. The liveness helper's own catch still maps every non-EPERM error to "dead". The fix belongs where the value stops being trustworthy rather than at the far end of it, but that helper is worth revisiting on its own terms.

sim	c2d5b528e5	refactor(#3103): give the reap and worktree-info paths the seam their callers already have ... Twenty-two branches in the orphan-reaping path are unreachable from the test suite, and the reason is not that they are hard to reach — it is that nothing can reach them. The reaper already accepts an injectable dependency bag, but every test drives real git and injects only the clock and the liveness probe, so each fail-closed return inside it has never executed under test. The two entry points above it took no dependencies at all, so a test could not drive them even if it wanted to. Both now accept the same bag and thread it down, with stdout and stderr writers defaulting to the process streams. The worktree-info probe in the base-branch resolver called its git seam directly while a sibling function in the same file already modelled the injectable form; it now follows that sibling rather than inventing a second convention. Every parameter defaults to today's real implementation, so no existing caller changes behavior. This is a testability seam, not a redesign. Two guards are removed as genuinely dead, each excluded by a check a few lines above it. A NaN test on a value captured by a digits-only pattern cannot fire, because parseInt of digits is never NaN. An emptiness test on a capture group that matched one-or-more non-space characters cannot fire either. Each site keeps a one-line note naming the guard that excludes it, so neither gets restored by a future reader. A third guard was proposed for deletion on the same grounds and is NOT removed, because the claim was wrong. The local-branch fallback returns null when git prints output that is non-empty but names neither branch — the emptiness check above it only catches the empty string, so a single newline reaches the fallback with both flags false. Deleting it would have changed which branch the resolver reports. It stays, and it gets a test. Refs #3057 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-08-06 00:32:28 -04:00
Tom Boucher	53ea8e0664	fix(#3057): make a guard's failure distinguishable from its benign result — Wave 1 (#3088) ... * fix(#3057): refuse the write when the duplicate scan cannot complete writeManifest documents itself as a fail-closed duplicate guard: if any existing manifest shares plan_id with a different, non-terminal job_id it must refuse, because dispatching again would duplicate the external job. It could not honour that. The scan reads every sibling manifest looking for the duplicate, and an unreadable or unparseable sibling was `continue`d past. If the corrupt file was the one holding the live duplicate, the scan found nothing and a duplicate external job dispatched. The asymmetry is what gives it away: a malformed TARGET refused with malformed_existing because clobbering is unacceptable, while a malformed SIBLING was skipped — yet siblings are the only thing the duplicate check reads. Adds a scan_incomplete verdict that refuses and names the offending file, so an operator can quarantine or repair it. Fail-closed alone would let one stale corrupt manifest wedge every dispatch for that planning dir permanently; naming the file is what makes refusing survivable. malformed_existing is untouched, so the target/sibling distinction stays visible. The docstring is updated — it previously stated a rule the function did not keep. memFs() gains an optional failReads map so these branches are reachable at all; they had zero coverage because the fake could not express a per-file read fault. The signature is additive and every existing caller is unchanged. The regression is proved by a pair, not a single test. A control writes a readable sibling holding a genuine non-terminal duplicate and asserts duplicate_plan_id, establishing the scenario is real; the regression then makes that same path unreadable and asserts scan_incomplete. A first draft of this test used a corrupt-JSON fixture containing no plan_id at all while its comment claimed otherwise — it duplicated the unparseable-sibling case and proved nothing, which is the defect class this phase exists to remove. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3057): make a guard's failure distinguishable from its benign result Wave 1 of the negative-space backfill: the branches where a guard that could not verify something reported the same value it reports when everything is fine. That indistinguishability is the defect; every fix here makes the two states tellable apart, and every test proves it with a pair — one for the failure, one for the benign case. A single test cannot establish that two states are distinguishable, which is the whole property being fixed. state.cts phaseInventoryProvider returned null for both a real disk-scan failure and a genuinely empty phases dir, so `state rebuild` could report success while phase-table reconciliation never ran. It now returns a discriminated result and the CLI surfaces phase_inventory_scan_failed plus a reason. The reason field turned out never to have been wired into the emitted JSON at all — it existed only as an internal variable — so a test could only assert on the operator-facing note. It is a real field now. state.cts treated an unreadable lock body the same as an empty one, applying the 1-second stealable floor. A lock we cannot read is not a lock we know is stale; an unreadable body is now held to the deadman ceiling like a live holder. verification.cts findStaleVerificationSummary returned null on any fs, scan or clock failure — meaning "not stale". It now returns a discriminated StaleCheckResult and the caller records that the check was indeterminate. git-base-branch resolveBaseBranch returned 'main' both when no candidate branch existed and when every git tier timed out. A diagnostics variant now reports whether the answer was verified, and the CLI writes an unverified-fallback note to stderr. The stdout contract five workflows parse is untouched. worktree-safety snapshotWorktreeInventory left exists:true when statSync threw, so a guard that could not check reported the worktree present; exists is now tri-state and a stat failure surfaces as an 'unverified' finding. planWorktreePrune reported 'no_worktrees' for a parse failure, which is not the same as an empty list — and it drives a prune. It now reports 'parse_failed'. Fixing the inventory change exposed a second fail-open in verify.cts: the validate-health consumer silently dropped findings whose kind it did not recognise, so the new kind would have vanished. That is closed too — worth noting that the survey enumerated producers of degraded verdicts, not consumers that discard them. worktree-base-ref and state-transition gain the distinguishing signal without changing what they do: headAbsenceVerified, and a phase-inventory scan meta. Whether those guards should ACT differently is a product question this change does not answer, and both are flagged rather than quietly settled. rescueSummaryArtifacts is left alone: rescuing on an uncertain cat-file is deliberate per #2556. It now has tests proving it, and a recorded negative finding — git cat-file -e returns 128 for both "absent from HEAD" and a fatal error, so "uncertain" and "certain-and-fine" are not separable at the git level. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3057): assert typed values, not rendered text Ten assertions in the rebuild CLI suite matched substrings of produced output — STATE.md body fields, a markdown table row, an audit-log heading, and JSON keys read as text. CONTRIBUTING prohibits that: if the code under test produces text, the test asserts on its structured surface instead. No production surface had to be built. Every one already existed and was already compiled into bin/lib: stateExtractField for body fields, parseMarkdownTable for the phase table, collectSection for the audit-log section, and result.data.log — already a typed RebuildLogEntry[]. The tests were matching rendered text sitting next to the structured data. One of those assertions was passing for the wrong reason. `stdout.includes ('rebuilt')` matched the JSON KEY name, not a value: the dry-run path emits `mutated` and the real path emits `rebuilt`, so it would have passed whether the value was true or false. It now asserts the value. external-job's refusal already had to name the offending file — that naming is why the fail-closed variant is survivable rather than a permanent wedge — but the tests proved it by substring of a prose message. The failure result now carries offendingPath as its own field and the tests assert it by value. The human message is unchanged; operators read it. Array membership is left alone. `phaseIds.includes('99')` and `result.updated.includes('Completed Phases')` are membership checks on real arrays, not text matching, and converting them would weaken nothing and clarify nothing. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3057): execute acquireStateLock instead of grepping its source The non-EEXIST lock test asserted on the TEXT of the built .cjs and never called acquireStateLock. It carried an allow-test-rule: architectural-invariant exemption to permit that. A source grep proves a literal is present in a file, not that the behaviour works — it is weaker than a liveness test, which at least runs the code, and it was the only coverage the fatal-errno path had. Replaced with tests that inject the errno through fs and assert what actually happens: a fatal EACCES propagates out of acquireStateLock with zero backoff sleeps, while EAGAIN/EINTR/EINVAL/EIO/ENOENT/ESTALE/EPERM/EBUSY retry once and succeed. The exemption is removed and its allowlist entry with it. One old assertion is deliberately not carried over: it checked the retryable errnos were expressed as a Set rather than an inline literal. That is a shape check with no runtime signature; the behavioural tests fail if the code reverts to the old inline check, which is the regression it was really guarding. The #3057 lock-body tests move into that same file rather than a new one, which is what lint-test-file-count asks for and puts every acquireStateLock test in one place. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3057): surface an indeterminate staleness check to its callers An isolated review caught an inconsistency inside this wave. Two of the three "add the distinguishing signal" fixes wire through to something a user sees: git base-branch writes an unverified-fallback diagnostic to stderr, and an unverifiable worktree surfaces as a W020 finding. The third set staleCheckIndeterminate on readVerificationStatus's result and nothing read it. A signal nobody consumes leaves the fail-open exactly as silent as before: the staleness check could fail and the operator saw precisely what they would see if the answer were genuinely "not stale". That is the defect this issue exists to remove, so it is not defensible as scaffolding when its two siblings in the same change already wire through. All five callers now surface it, each through the channel it already had rather than a mechanism imposed uniformly: phase complete adds it to its existing warnings array and, on the blocked path, as an additive note on the error text; init and roadmap carry it as a field on output they already emit; the UAT report carries it without ever gating passed/blockers; workstream inventory takes an injectable writeDiagnostic mirroring the git base-branch idiom, because its return shape had nowhere to hang a per-phase field without rippling the builder's types. The routing decision is unchanged everywhere. What changes is only that a caller and an operator can now tell a failed check from a completed one. That diagnostic carries structured meta rather than being asserted by regex — the default still writes only the human message to stderr, but tests assert phaseDir and reason by value. Two earlier assertions in this branch were converted the same way; this was the last raw-text assertion left. Also records a scope correction: the completePhaseCore guards now compare stateReplaceField's result to the body instead of testing truthiness, so a field whose substitution produced identical text no longer reports as updated. That is a real behaviour fix, not the signal-only change this file was described as carrying, and its tests cover both the changed and unchanged cases. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3057): bound two heavy subprocesses for a loaded bench, not an idle one The remote matrix surfaced three failures unrelated to this branch's changes. All were bad tests, and a re-run would have hidden every one of them. The reviewer-flags parse block bounded bash -> node -> a full gsd-tools cold start at 5 seconds. On a bench running thirty thousand tests in parallel that is not a hang, it is a busy machine. Raised to 30s, matching the convention sibling suites already use for script invocations, with a comment saying what the budget covers so nobody tightens it back. Two further copies of the same 5-second spawn in the same file had the identical defect and are raised too — they were not in the failure report, but they will be next time. The fragment-propagation test bounded npm run regen:derived — a full build plus eight generators, the heaviest subprocess in the suite — at five minutes, and node22 was killed near the end. The captured output proves it: every generator had written its files and gen:install-tree had emitted all fifteen runtimes before the kill. Raised to fifteen minutes. That failure read as `null !== 0`, which says nothing. status null means killed, not a non-zero exit, and the two want different responses: one is a timeout to size correctly, the other is a real build break. The assertion now distinguishes them and names the signal. Neither test's assertions were weakened and no retry was added. A retry here would suppress exactly the signal the timeout exists to produce. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3057): capture fd 1 through the mock tracker, not a raw reassignment The phase suite reported zero test results on both lanes while running for five and a half minutes and exiting 1. No assertion text, no stderr, four events for the whole file: enqueue, start, dequeue, complete. That shape is not a failing assertion — it is the runner being unable to read the child at all, because it parses its event stream from the child's stdout. The cause was the capture helper reassigning fs.writeSync directly. Proven rather than assumed: a standalone probe patched fs.writeSync and called process.stdout.write, and the interception fired only when fd 1 resolved to a FILE, not when it was a pipe. The remote runner captures the event stream to a file, so a helper that was invisible against a pipe swallowed the reporter's own output on the bench. That is also why the two sibling suites wired the same way in this change pass cleanly — they use the mock tracker, the seam io.test.cjs established for this exact function. The helper now uses t.mock.method with an explicit restore after each call, so teardown belongs to node:test rather than a second hand-rolled implementation, and the interception cannot outlive the one synchronous call it wraps even if that call throws. Ten call sites thread the test context through; three test callbacks gained the parameter they lacked. The three B3 tests are untouched — same assertions, same fault injection. Only how the context reaches the helper changed. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3057): capture phase-complete output from a subprocess, not fd 1 Two attempts to make in-process fd-1 interception safe both failed on the bench. The suite reported zero test results on either lane while exiting 1 — four events for the whole file — because the runner parses its event stream from the child's stdout, and process.stdout.write routes through fs.writeSync whenever fd 1 resolves to a file, which is how the runner captures. Patching that seam anywhere in a file can therefore destroy the file's own reporting, and tightening the window only moved the runtime from 326s to 125s without recovering a single event. So the interception is gone rather than tuned. The helper now spawns gsd-tools as a real subprocess and reads stdout the way the OS already gives it to us, which is what the rest of the suite does. It asserts the command succeeded before parsing, so a genuine failure can no longer present as a JSON parse error. The two fault-injecting tests could not survive that move as written: a subprocess cannot see a mock installed in the parent. Instead of reinstating the interception they now produce the fault on disk — the summary artifact is created as a dangling symlink, so the staleness check's real statSync throws inside the child. That is a more honest fixture than a mock in any case, since it is a condition a user's tree can actually be in. Skipped on Windows, matching the existing symlink precedent in the write-guard suite. Three further call sites turned out to depend on parent-process writeFileSync mocks the subprocess could not see. Those call the CJS function directly, which is what they always wanted — they never needed stdout at all. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3057): one name for one signal, one encoding for one distinction Standards review found four things this branch introduced, all of them inconsistencies with itself rather than with the repo. One upstream bit reached its consumers under three names — verification_stale_check_indeterminate in two modules, the same value with "stale" dropped in a third, and stderr only in the fourth. Standardised on the long name wherever it is a field. The workstream inventory keeps its stderr channel, since its return shape has nowhere to hang a per-phase field without rippling the builder's types, but it now says the same word for the same thing. worktree-safety encoded one three-way distinction two ways in a single file: a named union for a finding's kind, and boolean|null for an inventory entry's existence. The second is now a named union too. Two assertions matched human prose because the blocked and non-blocked completion paths carried no typed field for the signal. Both now assert typed values. The first round of this fix added the field but left the regex beside it, which is the banned pattern sitting next to its own replacement; the second removed it and added an assertion on the reason enum so nothing was lost. The remaining two were reasoned away before being fixed, and both reasons were bad. "No typed surface exists" is the condition CONTRIBUTING says to fix by adding one — it took three lines. "The file already does this dozens of times" is not licence to add instance number thirty-one; a convention that violates a documented rule is debt, not precedent. Vocabulary differing across DIFFERENT modules is left alone: CONTEXT.md rejects a single shared result envelope, so per-module shapes are precedented, and a baseline smell does not outrank a documented standard. A census of every line this branch adds to a test file now finds no regex or substring assertion on produced prose: 87 strictEqual, 25 ok (all non-empty or shape guards), 12 equal, 3 throws (all typed err.code predicates), 3 deepStrictEqual, 2 notStrictEqual.

Tom Boucher	7e1004d89e	test(#3056): add the in-process fault-injection adapter, and normalize execGit's shape (#3077) ... * refactor(#3071): normalize execGit's call and result shape, unify ExecGitFn ExecGitFn was declared four times. Three were hand-copies of one signature and two of those were wrong: they typed exitCode as number|null when _spawnResult returns `result.status ?? 1` and can never yield null, weakened signal from NodeJS.Signals to string, and widened error from Error to unknown. Only verification.cts got it right, via `typeof execGit`. The root cause was a missing export: SpawnResultOutput was declared without `export`, so no other module could name the return type of execGit. Three authors independently hand-copied it instead. Exported now. Normalizing the type alone would have left the pressure that caused the divergence, so the function is normalized on both sides. It now ACCEPTS every call its consumers make — worktree-safety's declaration could not express an env-carrying call at all — and RETURNS every result code they need: timedOut moves into _spawnResult, so execGit, execNpm and execTool all carry it and the one extension that justified a separate type disappears. All four sites are now `typeof execGit` with nothing left to restate. timedOut reuses the existing isSpawnTimeout predicate introduced by #3050 rather than re-deriving it. That predicate checks error.code === 'ETIMEDOUT' only; the signal === 'SIGTERM' conjunct was deliberately dropped there because Windows does not reliably report SIGTERM and requiring it risks a false negative. There is no false-positive risk, and a test proves it: an externally-delivered SIGTERM leaves error null, so it is still not reported as a timeout. No dead null-checks surfaced. Every exitCode comparison in the two affected modules is === 0, !== 0 or === 128 — never a null guard — so the nullable declaration had never been written against. Closes #3071 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3056): add the in-process fault-injection adapter Adds tests/helpers/faulty-deps.cjs — makeFaultyGit() and withFaultyFs() — so a module's error branch can be driven deterministically and its degraded verdict asserted, instead of a counter-test that only proves the call did not throw. makeFaultyGit returns a value structurally assignable to `typeof execGit`, so one stub satisfies all four seams that the #3071 normalization collapsed into that single shape. A parity test drives the same stub through a real injectable entry point in each of worktree-safety, git-base-branch, worktree-base-ref and verification; it fails the moment any of them re-grows its own shape. Faults are scoped rather than global — by argv predicate and by call ordinal — because a fault adapter that faults everything looks like it works and proves nothing, and because verification.cts's two-call error handling needs to fault the second call only. Invocations are recorded so a test can assert an exact call count. The timeout fault carries error.code === 'ETIMEDOUT', and a test asserts the real isSpawnTimeout predicate matches it, so the fixture cannot drift from the production definition of a timeout. A companion test asserts an externally delivered SIGTERM with a null error is still NOT reported as a timeout — the false-positive guard for #3050's dropped conjunct. withFaultyFs restores in a finally so a throwing body still restores, patches only the named methods, and nests without clobbering an outer saved original. It never uses chmod: that no-ops under root, so the test would pass with zero coverage in root Docker/CI. The adapter is in-process via deps only. The Phase 1 process seam is documented as deliberately not a fault-injection surface — it cannot distinguish an injected timeout from a genuine bench OOM and would retry it. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3071): add changeset fragment for the execGit normalization Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3071): route the last two timeout checks through the shared predicate An isolated review found this branch had normalised the timeout verdict but left two callers still hand-rolling the fragile version of it. check-command-router's runBoundedShell computed `timedOut: r.signal === 'SIGTERM'` while the correctly-derived `r.timedOut` sat on the same result object. graphify's execGraphify branched on `result.signal === 'SIGTERM'`, with a comment asserting the very premise isSpawnTimeout exists to reject. Both fail in both directions. On Windows a genuine timeout is not reliably reported as SIGTERM, so the guard silently fails to fire — the false negative #3050 was raised for. And an externally-delivered SIGTERM is not a timeout at all, so the check also fires when it should not; isSpawnTimeout avoids that because `error` is null in that case and it keys on error.code. Both now read the derived `timedOut`, and graphify's comment states the actual rule instead of the fragile assumption. Also replaces a vacuous test: "execGitDefault now accepts env" never called execGitDefault (it is unexported), called execGit — whose signature already accepted env before this branch — and asserted only that exitCode was a number, which would pass whether or not the change under test existed. It now proves env reaches the child by asserting `git var GIT_EDITOR` returns the injected sentinel. Refs #3051 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3071): make the graphify timeout fixture faithful to a real timeout The remote matrix failed on both Linux lanes: graphify's "returns exitCode 124 on timeout" got 1 instead of 124. The fixture was wrong, not the production change. It stubbed spawnSync as { status: null, signal: 'SIGTERM', error: undefined }. That is not a timeout. A real spawnSync timeout also sets error.code 'ETIMEDOUT'; a SIGTERM with no error is an externally delivered signal — a kill. The old `result.signal === 'SIGTERM'` check accepted it as a timeout, which is the false positive the shared predicate exists to reject, so this test was locking that bug in rather than guarding against it. The fixture now carries a real ETIMEDOUT error and all three original assertions pass unchanged. A counter-test is added alongside it: an externally delivered SIGTERM with no error must NOT be reported as a timeout. That is the assertion whose absence let the false positive live. Swept every SIGTERM/SIGKILL stub under tests/ for the same unfaithful shape. No other instance: the worktree-safety, worktree-base-ref and commit-staging fixtures already set ETIMEDOUT, and the remaining hits are either deliberate external-kill tests or feed code that never consults timedOut. Two sites keep their own signal check deliberately and are NOT changed: capability-source.cts:1301,1386 fail closed on ANY abnormal termination, which is correct — reading timedOut there would stop it failing closed on a kill and let it parse stdout from a killed process. Their reason strings, and check-latest-version.cjs:115, label any signal as "timed out", which is imprecise wording over a correct verdict, not a silent failure.

Tom Boucher	8f75e27554	fix(#3045): fail closed when an executor dispatch drops its resolved isolation (#3069) ... * feat(#3045): deny an executor dispatch that drops its isolation flag Every isolation gate already resolved correctly. The resolved value then reached the executor through a prose instruction telling the model to substitute it into a call the model composes itself, and nothing verified the substitution. When it was dropped, the executor edited and committed in the user's primary checkout with no consent and no warning. A prose backstop would be the same class of artifact as the defect, so this is a shipped PreToolUse hook on the Agent tool. It fires at the instant of the call rather than being read once at the top of a workflow, which is the only placement the model cannot skip. The guard is inert unless it can positively establish that this is a GSD project, that the project resolves to harness isolation, and that the dispatch targets an executor. A non-GSD repo has no invariant to enforce. Where it cannot read the configuration at all, it denies rather than assuming, with its own reason -- a guard that cannot verify must not answer safe. A malformed payload allows rather than throwing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * feat(#3045): extend the isolation guard to Cursor Cursor is the second of only two runtimes that resolve harness isolation, so shipping the guard for Claude alone left half the exposed surface unguarded while the changeset implied it was covered. The two runtimes fail differently. On Claude the harness flag is a per-dispatch kwarg the model must copy into a call it composes, and the defect is that it can be dropped. On Cursor the flag is --worktree, which applies to the whole session, and the subagent-start payload carries no isolation field at all. There is no flag to check, so the guard verifies the effective state instead: whether the workspace is genuinely running outside the user's primary checkout. That is a stronger check than the Claude one because it tests reality rather than intent, and it is commented so nobody later rewrites it into a flag check. Isolation is established two ways, either sufficient: the workspace resolves to a linked git worktree, or it sits under the worktree root Cursor manages. The second matters because a directory Cursor placed there is a legitimate isolated session even before it becomes a distinct git worktree, where linkage alone would report no repository. Detecting linkage required a new primitive rather than the existing context resolver. That resolver short-circuits on finding a local .planning directory before it ever compares the git directory to the common one -- and an isolation worktree normally has its own checked-out .planning. Reusing it would have read a correctly isolated session as unisolated and denied it, which is the failure direction that gets a guard switched off. The comparison is now its own shortcut-free function that the resolver delegates to after its own shortcut, so existing behavior is unchanged, and the case that would have broken is pinned. The subagent type is checked before any configuration is read, so an unreadable config cannot deny a dispatch this guard would never have enforced against. The input-schema comment on the Cursor hook documented only the fields common to every event and omitted the ones specific to this one. That omission cost a halt during this work; it now documents both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): enforce the resolved dispatch decision, not the host capability The guard keyed on the registry's dispatch.isolation, which says only that a runtime is CAPABLE of harness worktrees. The decision that actually governs a dispatch is the one the workflow resolves after gating, and that legitimately comes out as sequential in three documented cases: a project setting use_worktrees false, a per-plan submodule intersection, and the base-check auto-degrade. The workflow tells the model to omit the flag in exactly those cases, and the guard was denying every one of them. The third case matters most. The preceding fix made the base-check degrade on git timeouts and a missing git binary, where it had previously answered "safe". That correction is right, and it means a transient hang now degrades to sequential far more often than before -- so the two changes composed into a trap where the workflow behaved exactly as designed and the guard blocked it. The workflow already resolves isolation in shell, deterministically, which is what makes it a trustworthy source in a way the model-authored call is not. It now records that resolved value through a dedicated verb, and both guards read it first. A fresh record is authoritative, so sequential dispatches pass untouched. Absent or stale, the guards fall back to the capability check combined with the project's use_worktrees setting, which still covers the case that never reaches the workflow. Also widened the matcher to accept Task alongside Agent, since a host that names the tool Task would otherwise leave the guard silently inert while implying coverage; stopped assuming Claude when no runtime is declared, which is the shipped default and would have demanded a Claude-only argument elsewhere; and made a non-git project inert rather than denied, since advising a worktree session is not actionable without a repository. The original diagnosis never modeled sequential mode as legitimate. That omission is what let this through, and it is now recorded there. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): record at resolution and bind the record to its dispatch Two independent reviews converged on the same failure: the guard was fail-open in a default install, so it did not catch the defect it exists to catch. A shipped project carries no runtime key, which made "runtime not confidently known" the common case rather than a corner one. A record asserting that isolation was required but carrying no flag then fell through to a capability lookup that answered "none", and the dispatch was allowed. The flag itself only arrived from a second shell block -- the same block a model dropping the argument would also skip. A test had pinned that behavior as intended. The record is now written by the resolver, as an unavoidable consequence of asking for the value, rather than by a step the model is told in prose to go and run. A guard against a prose-carried value cannot itself depend on prose. Mode, flag and identifiers are written together and atomically, so the flagless window is gone, and a record asserting isolation with no resolvable flag now denies instead of degrading. Runtime is also resolved from the installer's own recorded default, which makes confident resolution the normal case. The per-plan submodule gate degrades after the phase-level decision and never re-recorded, so a plan that legitimately ran sequentially was denied against a still-fresh phase record. It now records its own, scoped to the plan. A record also authorized any dispatch for four hours. One phase degrading to sequential could silently license an unisolated dispatch in the next. Records now carry phase and plan, the guards require them to match, and the window is minutes rather than hours -- the resolver rewrites it before every dispatch, so a long window bought nothing and only widened the hole. The flag validator rejected any value beginning with two dashes, which is exactly the form Cursor and Windsurf declare, so their real value could never have been stored. Writer and reader also derived the record path differently and diverged inside a linked worktree without local planning state. The predictable path remains a way to silence the control without leaving a trace in the diff. It grants no access an agent with shell does not already have, so it is documented as accepted rather than redesigned around. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3045): correct the staleness boundary and unmask a vacuous parity test The remote runner returned twenty failures. One was a real production defect the boundary case existed to catch: a record whose age exactly equalled the staleness window was treated as fresh, so it stayed authoritative for one tick past its own expiry. Freshness is now strictly inside the window. The parity test meant to stop the two guards' executor lists from drifting could never have failed. Its project fixture was a bare directory rather than a repository, so the non-git inert branch answered before the executor list was ever consulted. It asserted agreement it never actually measured. The fixture is now a real repository, like every sibling in the file. A test also asserted that Windsurf declares the worktree flag. It does not -- Windsurf resolves to no isolation by design, having no named concurrent dispatch to isolate. The test claimed a registry fact that was never true, and a comment in the resolver repeated it. Both corrected, and the test now proves what it should have all along: that the parser accepts any bare flag value, rather than one runtime's supposed value. The new guard was missing from the bundled-hook whitelist, which is the surface that decides what actually ships, and the per-plan gate had gained calls to the launcher without the preamble those calls require. The changeset carried parenthetical product descriptions the purity rule forbids. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3045): backfill changeset pr number Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3045): make the guard tests hold on Windows Two tests redirect HOME to control where the installer-persisted runtime default is read from. Node resolves the home directory from USERPROFILE on Windows and never consults HOME, so both silently read the real runner profile, found no recorded runtime, and asserted against a project the hook had not recognised. The production code was already correct in asking the platform rather than the variable; only the tests were wrong to assume one variable answers everywhere. The helpers now mirror the override onto both. The symlink spoofing test also created a directory symlink unconditionally, which needs elevated privileges on Windows. It survived on this runner, but it would fail on any host without them, so the creation is now attempted and the test skips explicitly when it cannot be done -- a bare return would have counted as a pass and hidden the gap. Skipping alone would have left the platform uncovered, so the behaviour it proves is now also driven in-process through an injected realpath, following the seam already used for the clock. That case no longer depends on privileges at all, and the end-to-end test keeps its original assertions wherever symlinks work.

Tom Boucher	24066e536e	fix(#3050): fail closed when a worktree guard cannot verify safety (#3054) ... * fix(#3050): fail closed when a worktree guard cannot verify safety Three places answered "safe" when they had not actually checked. The base-divergence gate held the clearest evidence against itself: within one function, an unresolvable fork ref correctly degrades, while an unresolvable HEAD twenty-five lines earlier returned "proceed". Because a timeout collapsed into the same branch as "not a git repository", a locked index or a stalled mount produced a green gate that had never resolved the fork base -- and that value decides parallel versus sequential dispatch. Timeouts are now distinguished from a genuine absence of a repository. A timeout degrades with its own reason and message; not-a-git-repo keeps today's non-degrading behavior, because there is no worktree concern there. The same conflation in worktree-context resolution is surfaced rather than silently falling back to the current directory. Worktree creation's root confinement was opt-in: omitting the root skipped the check entirely, leaving only the leading-dash and parent-segment guards. The sole caller always passed it, so nothing was exploitable -- it is now mandatory so a future caller cannot inherit an unconfined path by forgetting. The timeout predicate was checked against what Node actually emits on a spawnSync timeout, not only against the fixtures, so it cannot be a guard that fires solely in tests. Coverage is deliberately behavioral. The existing worktree suites -- 134 tests across two files -- require no production module and call no production function; they assert against prose and would pass with the implementation deleted. That is how three fail-open guards survived in a heavily-tested module, so the new tests drive the real resolvers through an injected git seam, with five of them pinning the paths that must NOT change. One existing test asserted the opt-in confinement behavior and was rewritten rather than left green against the corrected code. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(#3050): stop a CLI exit code leaking into the test process The runner reported the new file as failed while the file's own summary said nine tests passed and none failed. That signature is a non-zero process exit after a green run, not a failing assertion. Cause: the confinement test calls the worktree-create command function directly, and that function sets process.exitCode on its failure path as a CLI would. In process, that exit code became the test file's own exit status. The sibling suite already guards this with a save/restore wrapper and a comment naming the hazard; the new file simply did not follow the convention. It does now. Root cause is in the test, not the production code -- setting an exit code is correct behavior for a command entry point, and the existing convention exists precisely because tests call these functions in process. Verified by exit-code and active-handle probes rather than by re-running: exit was 1, is now 0, with zero lingering handles and all nine tests still passing.

Tom Boucher	97f2af29da	fix(#2852): isolate wave-cleanup blocks to their own entry (#3009) ... * test(#2852): add failing-first regression coverage for wave-cleanup isolation Adds the #2852 test matrix to executeWorktreeWaveCleanupPlan: per-entry block reasons must isolate to the blocked entry instead of aborting the rest of the wave, and a deletion must only block when another wave member's branch still touches the deleted path. These fail against the current implementation (RED) — the fix lands in the next commit. * fix(#2852): isolate wave-cleanup blocks to their own entry and scope the deletions guard to real dependents executeWorktreeWaveCleanupPlan aborted the rest of a cleanup wave on the first blocked entry (branch_mismatch, base_mismatch, worktree_dirty, merge_failed, etc.), dumping every remaining entry into `pending` untouched instead of evaluating it. Every per-entry block reason now isolates via `continue` instead of `break` + bulk pending push. The one exception is a failed --no-ff merge, which can leave repoRoot itself mid-merge: that path now attempts `git merge --abort` and only halts the remaining wave if the abort itself fails (an unrecoverable repo-level failure), matching every other block reason's isolation. The `branch_contains_deletions` guard also blocked any deletion unconditionally, even one nothing else in the wave depends on (the reported repro: folding a test file into a sibling and deleting the original). It now blocks only when another wave member's branch still touches the deleted path — computed lazily per wave so a run with no deletions pays no extra git call, and fails closed (still blocks) when a sibling's diff cannot be determined. * fix(#2852): eagerly cache each entry's own diff to fix an ordering bug in the deletions-overlap check The deletions cross-entry overlap check (previous commit) computed each "other" entry's touched-files set lazily, the first time some later entry's overlap check needed it. That is wrong: once an entry has already been merged earlier in the same loop pass, its branch becomes an ancestor of HEAD, and `git diff --name-only HEAD...branch` silently collapses to empty. A dependent entry that appears BEFORE the deleting entry in the manifest (and has therefore already merged by the time the deletion check runs) would be missed, letting a genuinely-depended-on deletion through undetected — a live violation of the negative-space acceptance criterion, caught by /code-review's Spec-axis before this shipped. Fixed by populating each entry's touched-files cache eagerly, during that entry's own turn in the loop, immediately before its own merge attempt (the only step that can move HEAD) — so every entry's diff is captured before it could possibly have been merged, regardless of manifest order. Adds a regression test reproducing the exact broken ordering (dependent merges first, then a later entry tries to delete the file it depends on). * refactor(#2852): extract shared git name-only line parser /code-review's Standards axis flagged duplicated parsing logic: `stdout.split('\n').map((l) => l.trim()).filter(Boolean)` appeared at both the per-entry deletion list and the cross-entry touched-files cache added by this fix. Extracted into parseGitNameOnlyLines(), used by both call sites, so the two can't silently drift apart. * revert(#2852): scope the fix to wave-isolation only, restore unconditional deletions guard #2852's own triage comment explicitly deferred the deletions-guard policy question as a separate product decision ("Policy/enhancement ask, not a defect ... Out of scope: deciding or implementing an opt-in mechanism for intentional deletions"). All four of the issue's actual acceptance criteria concern wave isolation only. The prior two commits on this branch built a cross-entry deletion-dependency heuristic that substituted a derived judgment for that deferred product decision — out of scope for a confirmed-bug fix. Reverts: getEntryChangedFiles, touchedFilesCache, the overlapUnknown fail-closed branch, parseGitNameOnlyLines, and the eager per-turn cache-population call. `branch_contains_deletions` now blocks unconditionally again (byte-identical trigger condition to pre-fix); the only change is `continue` instead of `break` + bulk `pending.push`, same as the other 7 block reasons. Keeps: the full wave-isolation fix (all 8 sites) and the merge_failed / git merge --abort recovery-and-carve-out, both squarely inside the issue's actual acceptance criteria. The deferred opt-in-for-intentional-deletions decision is filed as #3003, citing #2852's triage as origin. * refactor(#2852): extract blockEntry() helper to remove duplicated block-assembly across 8 sites /code-review's Standards axis flagged the repeated "result.status='blocked'; result.reason=...; result.stderr=...; results.push(result); ok=false;" shape at every one of the 8 per-entry block sites this fix touches. Extracted into blockEntry(), called at each site; each call site still owns its own continue/break decision. No behavior change. * fix(#2852): check actual repo state instead of git merge --abort's exit code The merge_failed recovery path decided "genuinely unrecoverable, halt the wave" based on whether `git merge --abort` itself exited successfully. That is not a reliable signal: git refuses many merges (e.g. "your local changes would be overwritten by merge") WITHOUT ever creating a MERGE_HEAD, in which case repoRoot's tree was never touched — but `git merge --abort` still fails with "There is no merge to abort (MERGE_HEAD missing)?" in that exact safe case. Trusting that exit code alone misclassified an ordinary per-entry merge failure as a repo-level one and stranded the rest of the wave — the exact defect #2852 exists to fix, reintroduced through the recovery path (caught in review). Fixed by checking repoRoot's actual state directly via `git rev-parse --verify -q MERGE_HEAD` after the abort attempt: MERGE_HEAD present means genuinely still mid-merge (unrecoverable, halt); absent means safe (isolate and continue), whether because no merge state was ever entered or because abort successfully cleared it. An unexpected git error or timeout degrades to the conservative "still mid-merge" answer rather than throwing or guessing. Rewrites the "unrecoverable merge_failed" test, which previously used the safe "There is no merge to abort" string as its unrecoverable example — that pinned the defect as correct behavior. Adds the missing case: an ordinary merge_failed that never entered a merge state must not abort the wave. * test(#2852): cover repoRootStillMidMerge's fail-closed branches /code-review flagged that the two conservative fail-closed branches of repoRootStillMidMerge (a timeout on the post-abort MERGE_HEAD check, and an unexpected non-0/1 exit code such as a fatal git error) had no test coverage — exactly the branches most likely to hide a mutation survivor (e.g. a flipped `timedOut` check or a flipped final `return true`). Adds both cases: each must halt the wave (fail closed) rather than assume repoRoot is safe when its state cannot be verified. * chore(#2852): backfill changeset PR number to 3009 --------- Co-authored-by: sim <sim@local>	2026-08-02 19:51:43 -04:00
Tom Boucher	6ad30f74b6	feat(#2584): Phase 3 — scheduler consumer + isolation adapters (#2635) ... Final phase of #2584 (ADR-1239 Codex-binding amendment). execute-phase now negotiates dispatch.isolation and dispatches through the matching adapter, so a wave's independent plans run concurrently on six runtimes instead of one — with no runtime=== branch in the scheduler. harness-worktree passes the host's declared isolation flag (claude, cursor); orchestrator-worktree creates the worktree via the Phase-2 verb and spawns the executor into it with the resolved argv/cwd (codex, opencode, kimi, kimi-code); none stays sequential. Undeclared/unknown/unresolvable isolation degrades to none — never an unisolated parallel run. Fixes two shipped Phase-2 descriptors that per-host research found would fail at spawn: kimi lacked its headless flag (would launch the interactive TUI and hang the orchestrator), and kimi-code named a non-existent binary (Kimi Code installs as 'kimi'). Adds the worktree-path root confinement Phase 2 deferred here, and leading-dash guards on the resolver's prompt/cwd matching the existing git-argument guard.

Bounded git (10s timeout, degrade-not-throw); all manifest read/parse/validate/dedupe precedes the single git side effect (no unmanifested-orphan on a bad manifest); timeout-only best-effort partial rollback (a clean collision-exit never removes a live peer worktree); fail-closed on bad base, unsafe leading-dash / .. inputs, and malformed/mis-shaped manifest. resolveOrchestratorExec (host-integration.cts): pure descriptor->argv resolver reading the new runtime.orchestratorExec descriptor field (codex/opencode/kimi/kimi-code), fail-closed on missing/invalid shape.

First batch importing already-migrated siblings (configuration, model-catalog, shell-command-projection, redaction, security) via ./sibling.cjs specifiers. Strict type narrowing (typeof guards over String(unknown)); behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 5 large Wave-2 modules to TS (batch 6) ADR-457 build-at-publish: graphify, install-profiles, intel, installer-migrations, worktree-safety. installer-migrations preserves its dynamic require() loader for numbered migration modules (scoped lint suppressions). Strict typing (typeof guards over String(unknown)); behaviour preserved; suite 3030 pass, lint 0 errors. Wave 2 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate Wave-3 modules to TS (batch 7) ADR-457 build-at-publish: planning-workspace, runtime-artifact-layout, command-routing-hub, drift. Uses `import x = require()` for export= siblings; drift's lazy require of runtime-slash hoisted to a top-level import (verified non-circular). Behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate small Wave-4 modules to TS (batch 8) ADR-457 build-at-publish: cjs-command-router-adapter, phase-command-router, surface, roadmap-upgrade. Typed the hub router handler results as the HubResult discriminated union; surface drops 4 genuinely-unused imports. Behaviour preserved; suite 3030 pass, lint 0 errors. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate core hub (2.5k LOC, 68 dependents) to TS (batch 9) ADR-457 build-at-publish: get-shit-done/bin/lib/core.cjs -> src/core.cts, preserving all 63 exports via export=. All sibling deps already migrated (shell-command-projection, model-profiles, model-catalog, worktree-safety, planning-workspace, project-root, configuration, config-schema). Strict types, no any/ts-ignore; config-schema lazy require hoisted (non-circular). Behaviour preserved (independently verified: core's shard 3030 pass / 0 fail). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537): make ESLint-coverage + test-sprawl checks migration-aware #551 test hardcoded 12 now-migrated modules as "hand-written, must be linted"; that invariant is obsoleted by the ADR-457 migration. Rewrite it to a filesystem-driven invariant that holds at every stage: a bin/lib/*.cjs must be eslint-ignored IFF it has a src/*.cts source (tsc-generated), else linted (covers package-identity, which has no TS source). Also eslint-ignore config-types.cjs (has a src counterpart) and drop the redundant tests/clock.test.cjs (clock already covered by clock-seam + bug-474 tests), which tripped the lint-test-file-count ratchet. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 9 Wave-5 router/inventory modules to TS (batch 10) ADR-457 build-at-publish: phases/verify/init/agent/task/validate/roadmap/state command routers + workstream-inventory. Router handler results typed against core's exported shapes; behaviour preserved (caught+fixed a --verify boolean flag regression mid-migration). Full suite green across all shards (only the 4 local gpg-env changeset-notes failures remain; CI passes them). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 7 Wave-5 modules to TS (batch 11) ADR-457 build-at-publish: gap-checker, docs, check-command-router, frontmatter, learnings, gsd2-import, profile-pipeline. Behaviour preserved; full suite green across all shards (only the 4 local gpg-env failures remain). Also broadens atomic-write-coverage.test.cjs to accept the tsc-compiled namespace-import form while still asserting platformWriteSync is called (safety guard intact). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate config + profile-output to TS (batch 12) ADR-457 build-at-publish: config (729 LOC), profile-output (1142 LOC). All exports preserved; cmdMigrateConfig de-asynced (migrateOnDisk is sync, awaited caller tolerates it). Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Wave 5 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate 5 Wave-6 modules to TS (batch 13) ADR-457 build-at-publish: template, uat, workstream, roadmap, audit. Behaviour preserved (dead toPosixPath import dropped from audit; inline requires hoisted). Suite green across all shards (only the 4 local gpg-env failures). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate commands + state hubs to TS (batch 14) ADR-457 build-at-publish: commands (1305 LOC), state (2074 LOC, 17 dependents). All exports preserved; inner requires kept non-hoisted where load-order matters (install.js, per-call security); acquireStateLock cast inlined to preserve the err.code source token a structural test inspects. Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Wave 6 complete. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate milestone to TS (batch 15a, hand-authored) ADR-457 build-at-publish: milestone -> src/milestone.cts. Authored directly (subagent capacity was unavailable). Also relaxes core.output()'s 3rd param to optional, matching its real always-optional call contract (unblocks remaining 2-arg output callers). Behaviour preserved; suite green across all shards (only the 4 local gpg-env failures). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537): migrate phase, verify, init to TS (batch 15, final modules) ADR-457 build-at-publish, Wave 7 (the last hubs): phase (1608 LOC), verify (1615), init (2113). Adds src/package-identity.d.cts so verify can import the permanently value-baked package-identity.cjs under strict TS. Fixes two regressions the migration introduced in verify: restore cmdValidateHealth's `return result` (callers/tests read result.warnings — it is NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour intact). Full suite green across all shards (only the 4 local gpg-env failures); lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is deleted per ADR-457's final step. Also gitignore the tsc-generated config-types.cjs (was still committed) for consistency with every other emitted artifact. package-identity.cjs stays value-baked (declared via src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g <dir>` and git installs run the `prepare` lifecycle — which was missing — so the unpacked install shipped without the compiled .cjs and failed at startup with "Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job). Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does NOT run for registry consumers (they get the pre-built tarball), only for source/local/pack installs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are always present on disk: - check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the `prepare` build (tsc) — but it runs before deps are installed, so tsc is absent and it misreported the lockfile as out of sync. Add --ignore-scripts (a lockfile check must not build). - the lint-tests job installs with --ignore-scripts (no prepare build), but lint:skill-deps require()s the built install-profiles.cjs. Add an explicit `npm run build:lib` step after install. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step) prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`, which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT — breaking it with "Invalid format". build:lib (tsc) is silent on success and is all the unpacked/source install needs (the smoke-unpacked assertions exercise gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches prepack. build:hooks still runs on prepublishOnly for real publishes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * fix(#537): wire Stryker mutation gate to build-at-publish layout The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were generated artifacts and (b) included modules with no coverage in the command's test set. Rework: mutation.yml now derives changed COVERED modules from src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc was ~3x over the 30-min CI budget). NOTE: with the gate now correctly measuring the covered modules, their actual mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap (adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver — a maintainer decision. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537): raise mutation coverage of covered modules above the 50 gate Adds focused example-based unit tests that kill surviving mutants in the two lowest-scoring covered modules: - tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9% - tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4% Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered modules now scores 82.25% (>= break 50); every covered module is >= 68%. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix The serial Stryker run timed out at 30 min once the migration's added tests made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the gate completes well under budget — folded into this PR (was tracked as #609) because it's a prerequisite for this PR's mutation gate to pass. - scripts/mutation-matrix.cjs: single source of truth (covered-module -> test files) computing changed covered modules from git diff -> {has_work, matrix}. - mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name "Stryker mutation score (changed files only)" so branch protection is unchanged. Per-shard jobs report as "Stryker (<module>)". - stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back to the full command locally). Closes #609. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note Per-module sharding revealed that active-workstream-store (46.5%) and frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from the bloated 300-test command; on their own tests they were below the gate. Add focused unit tests: - tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9% - tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4% Both wired into scripts/mutation-matrix.cjs (per-module test map) and stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50 with only their own tests (config-schema/context-utilization/prompt-budget/ adr-parser already did). Also removes the leftover blacksmith TODO comment — GitHub-hosted runners only; speed comes from parallel per-module shards. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the way the per-module CI shard runs it) — an earlier ~98% reading was inflated by accidentally running the full multi-module command. Add 96 targeted tests to tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans): scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear the gate on their own tests.
