fix(#4302): bound restatement detector's deferral window structurally, not by a flat char count (#4303)
* test(#4302): add failing regression test for deferral-window paragraph leak RED: hasNearbyDeferralMarker's 500-char trailing window has no structural boundary, so a compact citation-free restatement immediately followed by an unrelated section that cites tdd.md borrows that neighbor's citation and evades restatesCycleStructurally(). Reproduces the exact shape confirmed via mutation testing against the real agents/gsd-executor.md. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4302): bound the deferral window at the next heading, not a flat char count hasNearbyDeferralMarker's 500-char trailing window had no structural boundary, so a compact citation-free restatement immediately followed by an unrelated section that cites tdd.md borrowed that neighbor's citation and evaded restatesCycleStructurally() (confirmed on the real gsd-executor.md, whose next section after the cycle pointer has its own independent citation 82 chars past the REFACTOR anchor). First attempt bounded at the next blank line instead, and was rejected after it broke a real case caught by direct execution before committing: execute-plan.md's FIRST RED/GREEN/REFACTOR occurrence is a numbered list's own intro sentence, separated by a genuine blank line from the list item that actually carries the citation — a blank line is not reliably "still the same statement" once list structure is involved. Bounds at the next markdown heading (`\n#`) instead, capped at 500 chars as before when no heading appears. Verified against both real files, the new regression fixture, and every pre-existing #4268 fixture/property test. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#4302): close a narrower same-section evasion found by orthogonal review The heading-only fix left a narrower gap: a citation-free restatement followed by a blank line and an unrelated PROSE paragraph (no heading) that cites tdd.md for an unrelated reason still evaded detection — confirmed by the reviewer via execution. Generalizes the boundary rule: any blank line whose following line is NOT a markdown list continuation is now also a boundary (in addition to the existing heading boundary), reconciling with the earlier-rejected flat blank-line bound by adding the list-continuation exception that execute-plan.md's real shape (a numbered list's intro sentence, then a blank line, then the list item carrying the citation) needs. Verified against both real files, all three restatement fixtures (heading-bounded, prose-bounded, list-continuation negative-space), every pre-existing #4268 fixture, and the fast-check property test (200 runs). Also restores an honest, updated limitation disclosure describing the one narrower residual case not resolved by this design (a citation reachable via exactly one list-item hop from an unrelated list) — matching this repo's disclosed-not-silently-deferred practice from the original #4268 PR.

fix(#4268): harden tdd-single-statement.test.cjs against reworded restatements and backend divergence (#4297)
* test(#4268): harden reworded-restatement and backend-predicate-divergence detection tests/tdd-single-statement.test.cjs's restatesCycle() keyed on the exact literal `commit: `test({phase}-{plan})`` substring, so a reworded restatement of the RED/GREEN/REFACTOR procedure shipped green. Adds restatesCycleStructurally(), a structural (span + list-marker) detector that stays linear-scan (per the #4228 catastrophic-backtracking incident this must not reintroduce) and is proven, empirically, to flag a paraphrased multi-step fixture while not flagging the real compact citations in execute-plan.md and gsd-executor.md (#4267's legitimate pointers). tests/tdd-backend-wiring.test.cjs never compared the two dispatch backends' `gsd_run query phase.tdd-applicable` calls against each other, so a one-word divergence between them (e.g. a changed --pick flag in only one backend) shipped green. Adds a byte-identity assertion on the command-substitution content (normalized for the two backends' differing variable-name prefixes), proven to have teeth via a RED-first mutation check before asserting it against the real files. The third gap in #4268 (nothing proves TDD_APPLICABLE has a real definition) was already covered by this file's existing assertTddApplicableIsComputed (epic #4272 Phase 2, #4266) — verified by inspection, no new test needed. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * test(#4268): redesign restatement detector around deferral, not length Standards+Spec review of the prior commit proved by execution that a compact, no-list-marker restatement (under the 200-char span threshold) sails past the span/list-marker-only signal. Redesigns the primary check: the actual invariant is deferral, not length — a legitimate RED/GREEN/ REFACTOR mention always names tdd.md as the authority nearby, a restatement never does. Flags when no tdd.md/canonical reference appears within a 500-char trailing window past the cycle mention, regardless of length or list-marker shape; keeps span>200 and three-distinct-list-marker-lines as secondary defense-in-depth OR-conditions. Verified independently against both real files (execute-plan.md span=10, gsd-executor.md span=14, both with a nearby deferral marker at +228/+82 chars) — no false positive, and the reviewer's exact gap class (a 189-char no-citation paraphrase) is now flagged. Also fixes: boundary coverage at the span threshold (199/200/201, isolated via a factored-out measureCycleSpan() helper), a fast-check property test proving the fix holds for arbitrary filler text, and a fragile line-match in tdd-backend-wiring.test.cjs that happened to work only because a FATAL echo message containing the same substring came later in document order than the real assignment line.

fix(#3990): state the RED/GREEN/REFACTOR cycle once, embed tdd.md conditionally (#4228)
* test(#3990): the RED/GREEN/REFACTOR cycle is stated once, embedded conditionally * fix(#3990): state the cycle once — pointers in consumers, conditional tdd.md embeds Emitted-Drift-Ack-Growth: execute-phase.md — #3990 conditions the tdd.md embed on the dispatch being TDD * chore(#3990): changeset for the single-statement TDD cycle * chore(#3990): backfill changeset pr number * fix(#4228): linear cycle check — the lazy-span regex pinned a Windows core for the whole job cap * test(#3990): allowlist pin tracks the rebased line * fix(tests): npm-integrity gate names an empty audit output explicitly — empty stdout crashed the parse as a bare SyntaxError * fix: name an empty npm-audit stdout explicitly — it crashed the parse as a bare SyntaxError Observed on CI (several branches, all lanes): spawnSync npm ETIMEDOUT with empty stdout; the empty string survived the recovery path and surfaced as 'SyntaxError: Unexpected end of JSON input', hiding the captured error. The recovery path now requires non-empty stdout, and an empty result throws with the captured stdout/stderr/message so the actual error is on the record. Root cause of the ETIMEDOUT itself is NOT diagnosed here — this change only stops masking it. --------- Co-authored-by: sim <sim@local> |
