fix(#2914): per-PR ack fragments instead of one shared mutable file (#2923)
* fix(#2914): never persist a spent emitted-drift ack on next tests/emitted-drift-ack.json held 34 spent #2834 entries merged via #2900. Every entry is scoped to the diff that introduced it (#2789), so once merged to next it is at the base by definition -- spent and inert. Its presence is still load-bearing though: each PR rewrites the paths map wholesale, making a persistent base copy a shared cell. Five of six conflicting PRs in the open queue collided on this file and nothing else. Deletes the stale document and adds a push-to-next guard asserting it stays absent. The guard is deliberately NOT wired into lint:ci -- a PR-lane check against the base is the #2768 shape #2789 exists to end. Closes #2914 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#2914): backfill changeset pr number Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#2914): per-PR ack fragments instead of one shared mutable file The emitted-drift acknowledgment lived in a single tests/emitted-drift-ack.json whose paths map every PR rewrote wholesale. That is a shared mutable cell: any two PRs needing an ack edit the same lines and conflict. Five of six conflicting PRs in the open queue collided on this file and nothing else. Acks now live as per-PR fragments under tests/emitted-drift-acks/, the same shape .changeset/ already uses to solve this exact problem. Two PRs pick different filenames, so they cannot collide, and fragments lingering on next are harmless rather than toxic. The legacy file's 35 entries are MIGRATED into a fragment, not deleted. An earlier delete-only attempt failed verification twice: the ratchet lost the spec-phase.md acknowledgment from #2779 and reported a 10-byte growth with no ack. Relocating preserves every acknowledgment. The legacy single file is still READ (unioned with the fragments) because five open PRs carry it; dropping support would break all of them. A duplicate path key across sources is a hard error, never last-wins. The push-to-next guard is retargeted accordingly: it now asserts only that the legacy SHARED file never reappears on next. Fragments may persist harmlessly. Closes #2914 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 5 <noreply@anthropic.com> |

fix(#2789): scope the emitted-drift ack to the diff that introduced it (#2803)
* fix(#2789): scope the emitted-drift ack to the diff that introduced it Every input to `diffEmitted` is base-relative -- `baseline` vs `current`, `changedPaths` from `git diff base...HEAD` -- except the ack set, which was read absolutely, from the working tree only. A differential machine consulting a non-differential input. So `staleAcks` asks exactly one question, "did a delta consume you?", and that cannot distinguish an ack that never explained anything (an authoring mistake) from one whose ripple is now absorbed into the base (the ack's SUCCESS condition). After merge an ack is in the second state but reports as the first. The trigger is ordinary. Actions sets GITHUB_BASE_REF on pull_request events only, so a push to `next` falls through to origin/next -- the very commit under test. Both sides build identical content, no deltas remain, and every live ack is reported stale. PR #2768 acked a deliberate 40866 -> 42020 byte growth, was green on its own lane, and reddened `next` the moment it merged. It also reds every PR branching off the poisoned base, and since publish-emitted-baseline is gated on the test job, it blocked baseline publication too. Give the ack the base side it was missing. `diffEmitted` now takes `baseAck` -- the same document at the base ref, via `readAckFileAtRef`. An entry already present there is SPENT: it may no longer consume a delta and is never reported stale, only surfaced as `spentAcks` for tidying. An entry new or reworded in this diff stays live, and if nothing consumes it that genuinely fails, with blame on the author who just wrote it. This closes a hazard the IMPLEMENTATION named but could not prevent -- a leftover ack silently pre-clearing the next ripple on its path. (ADR-2719 §3 asserted only that TOUCHING the file is the alarm; its residual-risk list never covered pre-clearing, and §3 now carries an amendment.) Verified against the two-PR laundering sequence -- land an innocuous ack, then change the artifact -- which passed silently before and now fails on both the hash pass and the size ratchet. Three things the design has to get right, each of which was wrong first: - A read failure on the base document THROWS; only absence-at-the-ref returns null. Returning null on error LOOKS armed (every entry stays live) but a live entry's defining power is that it CONSUMES a delta, so null is armed on the staleness axis and DISARMED on consumption -- silently the whole pre-#2789 gate. `git show` cannot tell absence from fault, so absence is established with `ls-tree`. - Re-arming a spent ack costs actual PROSE. Internal whitespace and the zero-width family collapse, and `runtime` is not compared: a doubled space, an invisible character, or a decorative field would otherwise re-arm an ack whose justification still describes the previous ripple, showing a reviewer nothing. - `baseAck` is REQUIRED once an ack declares entries -- omission is an error, not a silent "inherit nothing" -- so a dropped argument fails loudly instead of quietly restoring this bug with the suite green. Because a corrupt document ON THE BASE is expensive (the loud base-side failure reds every ack-carrying PR), scripts/lint-emitted-drift-ack.cjs blocks one from landing. It is standalone rather than importing parseAck -- scripts/ ships in the npm package and tests/ does not -- so a parity test runs both surfaces over one corpus and fails on divergence; it caught one immediately, a `null` document, now classed as policy rather than schema. Deadlock is separately foreclosed: a tree carrying no ack never reads the base, so the PR that DELETES a corrupt file still lands. `readAckFileAtRef` takes an injected git runner so all four branches are tested deterministically; it never executes in the remote runner, where the real-tree test skips for want of a base ref. It also refuses an option-shaped ref, since execFileSync's array form stops shell metacharacters but not git's own option parsing. Rejected: skipping the differential when base == HEAD. It treats the symptom, costs real coverage on the push-to-next lane, and does nothing about the downstream PRs the same flaw was reddening. Deletes the now-spent tests/emitted-drift-ack.json, and updates the CONTEXT.md canon and ADR-2719 §3: presence is no longer the alarm -- a LIVE entry is, and a spent one is inert.

enhance(#2778): make the size-ratchet failure name its own remedy (#2780)
* fix(#2778): exempt intentionally-absent paths from the glossary gate check-glossary-refs asserts that every backticked tests/ token in CONTEXT.md resolves on disk. tests/emitted-drift-ack.json (ADR-2719 section 3) is absent on a healthy next BY DESIGN — it appears only inside a PR that needs it, which is what makes touching it the alarm. It passed before only by accident of backtick pairing: CONTEXT.md's RULESET entries are themselves backtick-wrapped and contain backticks, so the token happened to fall outside a code span. Any edit that shifted the parity exposed it. A gate that passes by luck is not passing. The exemption is exact, not a prefix hole: a sibling missing tests/ path still fails, and a test locks that. * feat(#2778): make the size-ratchet failure name its own remedy The growth branch stated a requirement and withheld the means of satisfying it: no ack file named, no schema, no key format, and no do-not-regenerate line — so the likeliest guess was to hunt for a baseline that #2724 deleted. Observed live on #2543. All remediation now comes from one frozen REMEDIATION export whose example document is rendered from ACK_VERSION, so the taught schema cannot drift from the schema parseAck accepts. A round-trip test feeds the printed document back through parseAck. The report is now built as a typed IR (buildReport) that formatReport renders, so tests assert on structure rather than prose, per CONTRIBUTING.md's raw-text-matching rule. Two defects found and fixed inline while building: - diffEmitted's validation early-return omitted newFileCapExceeded while formatReport reads its length, so the branch that reports a failed git diff threw a TypeError instead of naming the problem. - Printing one complete ack document per failing branch made each read as the whole file, so pasting the second over the first silently lost an acknowledgment. One document now covers the whole report. Closes #2778 * chore(#2778): backfill changeset pr number to 2780 |

refactor(#2724): delete the committed golden fixtures and size baselines (#2767)
* test(#2724): delete golden-install-parity fixtures, test, and generator Removes the 19 committed path->hash manifests, the two per-file size baselines, tests/golden-install-parity.test.cjs, and scripts/gen-golden-install-parity-zcode.cjs. These were pure functions of the source tree (ADR-2719); the differential attribution check (tests/emitted-attribution.test.cjs + tests/emitted-provenance.test.cjs) is now the sole gate for emitted-artifact propagation. tests/fixtures/install-tree/*.json and tests/golden-install-tree.test.cjs are unchanged (ADR-2719 section 7 exception). Follow-up commits fix the resulting bookkeeping: scripts/ci-test-scope.cjs's existence guard, .gitattributes, package.json scripts, the emitted-provenance totality guard's IO, the differential check's baseline acquisition, CI wiring to publish/restore the baseline artifact, and docs. * refactor(#2724): make the differential attribution check self-sufficient Three fixes required to delete the golden fixtures without breaking CI: - scripts/ci-test-scope.cjs: remove tests/golden-install-parity.test.cjs from the three rules that named it. #2759's missingRuleTestFiles guard hard-throws at module load if a rule names a test file absent from disk, which would break the changes job on every PR the moment the fixture-deletion commit landed. - tests/helpers/emitted-provenance.cjs: loadManifests() read the committed golden fixture directory. With that directory deleted at every future ref, this would throw at module load forever, taking the Phase 2 totality guard down with it. Rebuilt from real installer spawns (MANIFEST_FAMILIES + runMinimalInstall + buildParityManifest), the same shape emitted-runtime.cjs's currentManifests() already uses. - tests/emitted-attribution.test.cjs / tests/helpers/emitted-runtime.cjs: the real-tree test's baseline acquisition swaps from baselineManifestsAtRef(base) (git show at a ref that no longer carries fixtures) to resolveBaseline()'s documented precedence: env, then the on-disk cache, then an in-job build. The build fallback (buildBaselineAtRef, new) checks out base into a throwaway git worktree and runs the new scripts/gen-emitted-baseline.cjs there -- no npm ci needed, since bin/install.js and the test helper shells are Node-builtins-only. That script also publishes the baseline artifact from CI's push-to-next job (wired in a follow-up commit). * refactor(#2724): retire the merge-driver bridge and per-file size baselines The Phase 1 bridge (#2721) is retired now that the artifacts it guarded are deleted: scripts/git-merge-regen-driver.cjs, its test, and the 'setup:merge-driver' npm script are removed, and the .gitattributes merge=gsd-regen/linguist-generated block for the three deleted-path globs is dropped. tests/fixtures/install-tree/*.json keeps its normal merge behavior, unchanged (ADR-2719 section 7). scripts/update-size-baseline.cjs and its test are removed: their sole purpose was regenerating tests/workflow-size-baseline.json and tests/agent-size-baseline.json, both deleted. The 'size:baseline' npm script and its step in 'regen:derived' go with it. The per-file baseline describe blocks in tests/workflow-size-budget.test.cjs and tests/agent-size-budget.test.cjs are removed for the same reason; the independent loose-tier hard caps are untouched. The differential attribution check's size ratchet (tests/emitted-diff.cjs, already shipped in #2723) is the replacement anti-creep mechanism. 'npm run gen:golden' is replaced by 'npm run gen:install-tree', which keeps regenerating tests/fixtures/install-tree/*.json (the one artifact family ADR-2719 section 7 keeps committed); tests/golden-install-tree.test.cjs's error messages point at the new command name. tests/golden-parity-single-source.test.cjs's anti-divergence guard (#2266) is retargeted from the two deleted golden-parity consumers to their two replacements (tests/helpers/emitted-runtime.cjs and tests/helpers/emitted-provenance.cjs), which import buildParityManifest the same way — the divergence risk the guard exists for is unchanged. Also wires CI: a new publish-emitted-baseline job runs scripts/gen-emitted-baseline.cjs after a push to next and caches the result keyed on the sha; the test and test-full jobs restore that cache on pull_request events, keyed on the PR's base sha, and export GSD_EMITTED_BASELINE for tests/emitted-attribution.test.cjs's real-tree test to pick up. * docs(#2724): flip ADR-2719 to Accepted and update contributor docs Status: Proposed -> Accepted. Regenerated docs/adr/README.md index. CONTRIBUTING.md, docs/TESTING-SUITES.md, and CONTEXT.md (RULESET. EMITTED_ATTRIBUTION, RULESET.WORKFLOW_SIZE_BUDGET, RULESET. AGENT_SIZE_BUDGET, and the Emitted Artifact Provenance glossary entry) no longer point at the deleted golden-install-parity fixtures, size baselines, gen:golden, UPDATE_GOLDEN, or the setup:merge-driver / git-merge-regen-driver.cjs bridge. Editing shipped content now requires zero manual fixture regeneration, documented against the differential attribution check instead of the deleted commands. * docs(#2724): add changeset for removed golden-parity commands * fix(#2724): drop stale scripts/update-size-baseline.cjs glossary ref check-glossary-refs.cjs verifies every backtick-wrapped scripts/*.cjs token in CONTEXT.md resolves to a real file. The RULESET. EMITTED_ATTRIBUTION rewrite named the deleted script inside backticks, which the checker reads as a live reference, not historical prose. * test(#2724): retarget ci-test-scope tests off the deleted golden test tests/ci-test-scope.test.cjs asserted specific RULES entries select tests/golden-install-parity.test.cjs, and that every rule selecting it also selects both emitted gates. Both premises broke when the golden test was deleted (#2724): the deleted filename never re-appears in targeted_tests, and there was no longer a third file for the gates to travel alongside. Retargeted the two selection describe blocks to assert tests/emitted-provenance.test.cjs directly (the drift guard the golden gate's rules were retargeted to), and simplified the third block to assert the two emitted gates always travel together, without reference to the golden filename. * docs(#2724): repoint two contributor how-to guides at the differential check Both guides told contributors to regenerate a baseline against tests/golden-install-parity.test.cjs, which #2724 deletes. Repointed at the differential attribution check (tests/emitted-attribution.test.cjs, ADR-2719), which needs no manual regeneration step. * fix(#2724): repair phase6-capstone-conformance's deleted-baseline read An independent orthogonal review caught a real regression this branch introduced into a test file the branch's diff never touched: tests/phase6-capstone-conformance.test.cjs read tests/workflow-size-baseline.json (deleted earlier in this branch) with no fallback, so the whole suite would throw ENOENT the moment this branch landed. The test's actual intent — prove the host-loop workflow files are real, tracked, non-empty docs — is preserved by asserting the live byte count via the same shared counter (scripts/workflow-size.cjs) the size guards already use, instead of a committed snapshot. Also, from the same review: a stale doc comment in scripts/workflow-size.cjs still named the deleted scripts/update-size-baseline.cjs as a consumer, and buildBaselineAtRef's cleanup in tests/helpers/emitted-runtime.cjs left two fs.rmSync calls unguarded against masking the primary result/error, inconsistent with the try/catch already wrapping the git cleanup beside them. Both fixed. A doc comment was added to baselineFamilyNamesAtRef explaining why it (and its siblings) are kept despite having no production caller post-cutover — they still answer real questions about refs that predate the cutover. * fix(#2724): repair three real regressions found by remote verification 1. tests/emitted-provenance.test.cjs's two hostile-input tests (non-object manifest, unreadable fixture) drove loadManifests(tmp) and monkeypatched fs.readFileSync, both premised on the deleted fixture-directory read this branch already replaced with real installer spawns -- the negative assertions silently stopped firing. loadManifests() now accepts injected {families, install, build, clean} (defaulting to production values), giving the tests a real seam to drive a bad build result and a build failure through the ACTUAL loader instead of a reimplementation, and added coverage that clean() still runs on both paths. 2. .github/workflows/test.yml's two 'Export GSD_EMITTED_BASELINE' steps hardcoded shell: bash, which is wrong on windows-latest (native pwsh) and on test-full's macos-latest legs (native zsh per that job's own matrix) -- the repo's H1 shell policy (tests/policy-shell-pinning .test.cjs) caught it. Replaced the inline bash script with scripts/ci-export-emitted-baseline-env.cjs, a plain Node script: a bare 'node <path>' command line has no shell-specific syntax, so it runs correctly under bash, zsh, and pwsh without a shell override. tests/phase6-capstone-conformance.test.cjs's deleted-baseline read (caught by the same remote run, at a commit prior to this one) was already fixed in d0c3b1242 and is not touched here; verified still passing after these changes. * fix(#2724): revive ADR-1610's new-file size cap inside the differential An isolated review caught a real regression: deleting tests/workflow-size-baseline.json silently dropped NEW_FILE_CAP (ADR-1610 Decision point 3, the Codex project_doc_max_bytes anchor) with no successor. tests/helpers/emitted-diff.cjs's size ratchet already 'continue's past any file absent from sizeBaseline -- exactly the files this cap exists to bound -- so a brand-new workflow file sized 32,769-40,960 bytes passed CI clean and shipped, then risked silent truncation at the Codex anchor at runtime. ADR-1610 is Accepted and never referenced anywhere in this branch. Fix: NEW_FILE_CAP=32768 revived inside emitted-diff.cjs's own size-ratchet loop, keyed off the SAME hasOwnProperty(sizeBaseline, name) signal the growth check already computes -- 'new' is exactly 'present in sizeCurrent, absent from sizeBaseline'. Not ack-able, matching the tier hard caps it sits beside: the fix is extraction, not an acknowledgment entry. Documented, disclosed narrowing: the pure differential module cannot see XL_WORKFLOWS/LARGE_WORKFLOWS tiering (tests/workflow-size-budget.test.cjs's classification), so a legitimately large new file must extract rather than tier in, one release earlier than an existing file would need to. ADR-1610 itself is left unamended -- this restores its decision rather than re-litigating it. Also fixes a stale comment plus a redundant real 19-installer-spawn assertion left over from the pre-injection-seam version of tests/emitted-provenance.test.cjs's build-failure test, and annotates 3 of 4 stale golden-fixture citations in docs/reference/host-integration-capability-matrix.md as superseded (the 4th is an accurate historical PR narrative, left alone). * fix(#2724): repair three red CI defects on the golden-fixture cutover Windows-only provenance false attribution (defect A): the `hooks-built` provenance rule attributed `hooks/<name>.cmd` to itself. Those shims are Windows-only installer output (ensureCodexHooksJsonSessionStart / ensureCodexHooksJsonEvent, both in src/runtime-hooks-surface.cts) wrapping the same-named `.js` hook — no `.cmd` file is ever tracked in the repo, so the self-attribution resolved to a path that exists on no platform. Only windows-latest ever emits the key, so this only failed there. Fixed by special-casing `.cmd` inside the SAME `hooks-built` rule (not a dedicated rule) — a dedicated rule would match zero paths, and therefore report as a dead rule, on every non-Windows lane of the same totality guard. `sources` already supported per-match functions; `transforms` is extended to support the same shape so the attribution can vary by match within one rule. Baseline bootstrap was structurally impossible (defect B): `buildBaselineAtRef` ran `scripts/gen-emitted-baseline.cjs` from INSIDE the base-ref worktree, but that script is new in this PR and therefore absent at any base ref that predates it — every call failed closed with "Cannot find module". Fixed by running the PR checkout's own generator against the worktree via a new `--dir` parameter, decoupling "which copy of the script runs" from "which tree it measures" (`currentManifests`/`currentSizes` gained a `repoRoot` override, threaded down to `runMinimalInstall`'s new `installScript` override). This is not just a bootstrap fix: a differential needs ONE measurement schema applied to both sides, or the two stop being comparable the moment that schema evolves — running each side's own copy would silently reintroduce that risk. Verified locally end-to-end against real origin/next: resolves a valid {version, sha, manifests, sizes} artifact with the correct sha and no leaked worktree. Changeset placeholder (defect C): `pr: 0` -> `pr: 2767`, which is what let docs-lint evaluate the fragment for the first time; it already passes (docs/TESTING-SUITES.md and friends already document the removed scripts). Also fixed while in this file: an eslint no-unused-vars warning surfaced by the changed lint run (unused `cleanup` import in tests/emitted-provenance.test.cjs). Added regression coverage for both A and B: a cross-platform spot-check that drives the real hooks-built rule against `.cmd` keys directly (not through a real Windows install), and a real-tree test that drives buildBaselineAtRef against a base ref verified (via git cat-file) to lack the generator, both skipping honestly rather than false-passing when their precondition does not hold. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W5kQs6ZufZDySC6zDJfYP6 * fix(#2724): repair false .cmd byte-provenance and a permanently-skipping regression test Two isolated-review findings on PR #2767: - `hooks-built`'s `.cmd` branch attributed the Windows shim's bytes to the wrapped `hooks/<name>.js` script, asserting a byte-provenance link that does not exist — traced against buildCodexHookWindowsShimIR (src/runtime-hooks-surface.cts), only the script's NAME (a literal in that same file) flows into the .cmd bytes, never its content. Point `sources` at HOOKS_WINDOWS_SHIM_SRC instead, matching the code-derived convention used elsewhere in the table. Since `sources` is checked before `transforms` in the differential, the wrong mapping silently excused any .cmd byte movement caused by editing the wrapped .js file. - The `buildBaselineAtRef` regression test skipped unless a resolvable base ref still lacked scripts/gen-emitted-baseline.cjs — true only until this PR merges, after which every base ref carries the file and the test skips forever with zero ongoing coverage. Rebuilt hermetically: synthesize the missing-generator condition in-place via git plumbing (a throwaway commit, child of HEAD, with just that one file removed from a scratch index), never touching the real working tree, HEAD, or index, and never depending on ambient history or remotes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W5kQs6ZufZDySC6zDJfYP6 * fix(#2724): tolerate the remote runner's dubious-ownership git mount in the emitted baseline path The runner container mounts the repo at a path owned by a different uid than the process running the suite, so git's dubious-ownership protection refuses every git operation there. GitHub Actions never hits this because actions/checkout registers the workspace as safe automatically; this runner's container does not. buildBaselineAtRef is the production build-fallback the sole remaining emitted gate depends on (resolveBaseline's in-job-build leg), not just a test helper, so the fix is in the shared git() wrapper (emitted-runtime.cjs) that every caller — resolveChangedPaths, resolveBase, buildBaselineAtRef's worktree add/remove/prune, and the hermetic regression test added in the prior commit — funnels through, plus gen-emitted-baseline.cjs's own rev-parse (now reusing that same wrapper instead of a second execFileSync, so the fix has one source of truth). Each call declares -c safe.directory=<the exact directory it already operates on>, never the * wildcard. Audited every other helper on this surface (emitted-diff.cjs, emitted-baseline.cjs, install-shared.cjs) for the same gap: none of them shell out to git at all.

fix(#2757): attribute transform-driven emitted changes and reclassify agents-verbatim (#2760)
* fix(#2757): let derived provenance rules attribute a transform change The Phase 2 provenance table (#2722) could only explain a moved emitted path via its `sources`, so a `kind: 'derived'` artifact whose TRANSFORM code changed (not its source) was unattributable by construction: 16 emitted agents/*.toml moved by PR #2566's runtime-artifact-conversion.cts change, with zero agents/*.md in the diff. Adds an optional per-rule `transforms: string[]`. A moved emitted path now attributes via its source OR its transform, reusing sourceSatisfiedBy so exact/prefix matching stays identical for both. Declared narrowly on agents-toml-derived and agents-verbatim (the two families verified to route through the same conversion pipeline) as src/runtime-artifact-conversion.cts, src/install-effort-resolver.cts, and src/model-catalog.cts — never bin/install.js, which would be a blanket escape hatch spanning every installer concern. Also corrects agents-verbatim from kind:'identity' to kind:'derived': measured against origin/next's own fixtures, the same agents/<name>.md hashes differently per runtime (e.g. codex vs claude), which a true verbatim copy cannot do. Verified empirically by installing every runtime and diffing against the raw repo source — none reproduce it byte-for-byte; every one rewrites frontmatter and the hardcoded .claude/ self-reference, and claude additionally gets an effort: line injected. A new assertNoIdentityTransforms invariant rejects an identity rule that declares a non-empty transforms list. Closes #2757 * docs(#2757): flag PR #2566's transform-role files for later verification src/agent-tools-contract.cts (added by #2566, absent on next) and src/agent-install-check.cts (modified +112/-1 by #2566, read-only today) were reviewed for prospective inclusion in AGENT_TRANSFORM_SRCS. Excluded for now: the nonexistent file would fail this fix's own "every declared transform path exists" hygiene test, and the modified file's future role cannot be verified without the unmerged PR's diff. Documents the reasoning, the interim ack-file safety net, and the verification method to apply once these files stabilize, so the next PR touching them has a pre-scoped one-line fix rather than a silent gap.

test(#2723): differential emitted-attribution check, dual-run beside the golden (#2737)
* test(#2723): differential emitted-attribution check, dual-run beside the golden Phase 3 of #2719. The conservation law itself, running BESIDE golden-install-parity.test.cjs -- both green, fixtures untouched. Every emitted path whose hash moved between next HEAD and PR HEAD must be attributable, through the Phase 2 table, to a path the PR actually changed. Unattributable deltas fail with the paths NAMED. The only way through is a committed acknowledgment, never a flag -- a contributor facing a red gate sets a flag, which is what UPDATE_GOLDEN=1 is today. The central decision is that the law is a PURE function (no fs, git, installer, or clock), with I/O confined to a separate resolver. The naive one-big-integration-test shape would need ~38 installer spawns per assertion, so #2723's four failing-first criteria would not in practice have been written -- which is exactly how a phase ships promised-but-not-built. Pure, they are millisecond table tests, and the Stryker gate can actually bite. Buckets are conserved: every moved path lands in exactly one of attributed | unattributable | acked, property-tested at 400 runs. A path the provenance table cannot resolve surfaces as an error, never a silent skip. Asymmetries that are deliberate, each with a test: - an ADDED emitted key is a ripple too, not just a modified one - synthesized paths are exempt; code-derived ones are NOT (Phase 2 refused to mark them exempt precisely because exempt means permanently blind) - shrinkage needs no ack; growth does. Gating shrinkage would punish exactly what the size ratchet wants - a STALE ack is a hard failure -- an ack outliving its ripple pre-clears the next one on that path - a failed `git diff` is an explicit error, never an empty changedPaths set; reading it as "nothing changed" would make everything unattributable and produce a failure storm that reads like a real finding - prefix sources are SEGMENT-aware, so `agents/` does not attribute `agentsfoo/x.md` Baseline is cached, not committed, keyed on the next sha. A stale key is refused rather than used: absence fails loudly and gets fixed, whereas staleness produces a confident wrong answer. An explicitly pointed-at GSD_EMITTED_BASELINE that is stale is a hard stop; a stale cache falls through to the in-job build. No baseline-unavailable path returns -- ADR-2719 section 6 names that trap, since in node:test a bare return is a PASS. Both the conservation property and the staleness gate were mutation-verified (injecting a swallowed key fails 9 tests; disabling the staleness comparison fails 5). Fixtures, generators, the merge driver and the ADR status are untouched -- those are Phase 4 (#2724). Refs #2719 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01W5kQs6ZufZDySC6zDJfYP6 * test(#2723): compute stale acks once, after the size pass Self-review defect found while the reviewers were running. `staleAcks` was computed twice: once between the hash pass and the size pass, then again after. Only the second value was returned, so the first was dead code -- and the dead one was placed where it would have been WRONG. An acknowledgment can be consumed by either a hash move or a size growth. Computing staleness before the size pass reports a legitimate growth ack as stale, which is a false failure that pushes a contributor to delete the very ack that is doing its job. Now computed once, after both passes, with a regression test. Verified by mutation: restoring the early computation fails 2 tests.

Every test was true of hand-built inputs and none of the repo, so the acceptance criterion "both this check and golden-install-parity green on the same tree" was trivially true rather than meaningfully true. That is the promised-but-not-built failure this epic keeps finding in its predecessors, recurring one phase later for the wiring itself. Taken, not argued. Adds tests/helpers/emitted-runtime.cjs -- the only module that touches git, disk, or the installer -- and an integration test that runs the same pure law against reality: - CURRENT side: 19 real installer spawns via runMinimalInstall + buildParityManifest, the same machinery the golden harness uses. - BASELINE side: `git show origin/next:<fixture>`. That is next's RECORDED emitted state and it costs nothing. Deliberately NOT the working-tree fixtures, which are whatever this PR's author regenerated -- comparing against those would be vacuous. Phase 4 deletes the fixtures and swaps in resolveBaseline's cache path, already implemented and tested. - changed paths from real `git diff --name-only origin/next...HEAD`, with the git subprocess bounded at 30s per CLAUDE.md's unbounded-subprocess rule. - the real tests/emitted-drift-ack.json (absent is legal; present-but-empty or unparseable throws rather than being read as absent). Verified it can actually fail: an uncommitted edit to a shipped workflow moves emitted output but never appears in the committed diff, and the check names all 18 affected emitted paths with the message format ADR-2719 §1 specifies. Restores clean. Also from review: - readAckFile now has a real test exercising the SUT across absent / valid / empty / unparseable / unreadable. The previous test asserted fs behaviour rather than SUT behaviour, because no SUT ack-reading path existed yet. - formatReport's sampleLimit gains true limit-1/limit/limit+1 coverage at 19/20/21. A test was previously NAMED "(limit+1)" while testing no numeric limit at all, which is worse than no coverage because it reads as covered. Windows uses an explicit t.skip (install output is platform-specific there, mirroring the golden harness) -- never a bare return, which node:test scores as a PASS.

The real-tree wiring enumerated Object.keys(RUNTIME_META) -- 18 entries -- while the emitted manifest set has 19 families. The 19th is claude-local: claude is the reference host and the only runtime with a distinct LOCAL "legacy flat-commands" layout (commands/gsd-*.md + agents/gsd-*.md at project scope), which golden-install-parity.test.cjs guards with a hand-coded test outside its RUNTIME_META loop (#2086). The family was dropped from BOTH sides, so the test's own self-check (current.length === baseline.length) passed vacuously at 18 === 18. A PR changing Claude's local-scope output would have failed the golden while this check reported ok -- and that disagreement is precisely what the dual-run window is designed to surface as a provenance-table hole. A wiring omission masquerading as one is the worst available failure here, because it would have been read as evidence about Phase 2 rather than a bug in Phase 3. Fixed by deriving MANIFEST_FAMILIES explicitly (18 global + claude-local at local scope) instead of inferring the set from RUNTIME_META. The self-check is also repaired: it now asserts both sides against the INDEPENDENT EXPECTED_MANIFEST_COUNT from the Phase 2 table, and asserts claude-local specifically. Comparing the two sides to each other can never catch a family missing from both -- the assertion has to come from outside. Verified by mutation: removing claude-local again fails the test. Also from the same review: - sourceSatisfiedBy returns the matched source string, so an empty-string source would return '' and the caller's `if (hit)` would silently discard a real match. Unreachable today (every rule source is a non-empty template) but a footgun for the next rule author; now `!== null`. - the purity fixture used a single-element changedPaths array, so an in-place sort would have been invisible. Now three elements in unsorted order.

The gsd-test runner shallow-clones and merges base+head, so no origin/* remote- tracking refs exist in the container. My own fail-loud path fired correctly; what was wrong was hard-depending on that ref existing. GitHub Actions has the same shape by default, which is exactly why changeset-required.yml carries an explicit `git fetch origin "${BASE_REF}:refs/remotes/origin/${BASE_REF}"`. Now resolved through an ordered candidate list -- GSD_EMITTED_BASE (explicit lane override), then origin/$GITHUB_BASE_REF and $GITHUB_BASE_REF, then origin/next and next -- de-duplicated, each verified with `rev-parse --verify <ref>^{commit}`. When NO candidate resolves the test takes an explicit t.skip() naming every ref it tried and stating that the gate did not run here. That is the ADR-2719 section 6 distinction: t.skip is REPORTED as skipped, whereas a bare return is scored as a PASS. Hard-failing was the other option and is wrong -- it would make the suite permanently red wherever a base ref cannot exist by construction, which is a statement about the checkout, not a propagation finding. The candidate ordering is pinned by a unit test rather than left implicit, since the ordering IS the fix.
