      "value": "the emitted-artifact family (ADR-2719, epic #2719) — POST-CUTOVER (#2724, Phase 4). Historically tests/fixtures/golden-install-parity/*.json (19 path→hash manifests) + tests/workflow-size-baseline.json + tests/agent-size-baseline.json were all committed, PURE FUNCTIONS of the source tree whose correct merge was ALWAYS \"recompute\" — 140 of 143 conflicted-file instances across the open PR queue were these files. #2724 DELETES all three, the golden test (tests/golden-install-parity.test.cjs), the generator (scripts/gen-golden-install-parity-zcode.cjs), `npm run gen:golden`, `UPDATE_GOLDEN`, the merge-driver bridge (scripts/git-merge-regen-driver.cjs, `npm run setup:merge-driver`, the .gitattributes merge=msd-regen block), and scripts/update-size-baseline.cjs (`npm run size:baseline`). The differential attribution check (tests/emitted-attribution.test.cjs + tests/emitted-provenance.test.cjs) is now the SOLE gate for emitted-artifact propagation AND size growth — no committed artifact, nothing to hand-merge, nothing to regenerate. `npm run regen:derived` still exists for what remains committed and derived: build, registry, ADR index, capability matrix, inventory manifest, manifest versions, and `tests/fixtures/install-tree/*.json` (now `npm run gen:install-tree`, folded into `regen:derived`). tests/fixtures/install-tree/*.json is DELIBERATELY EXCLUDED from the cutover (ADR-2719 §7): it conflicts on 0 of 7, its diffs are readable, and it preserves \"the installer stopped shipping X\" as a hard absolute failure — capturing it would convert that absolute into an attribution-free auto-resolve. The baseline the differential compares against is now published by `scripts/gen-emitted-baseline.cjs` on every push to `next` (cached, keyed on sha) and restored in PR lanes via `MSD_EMITTED_BASELINE`/`resolveBaseline()` (tests/helpers/emitted-baseline.cjs); a cache miss falls back to an in-job build via a throwaway `git worktree` (tests/helpers/emitted-runtime.cjs's `buildBaselineAtRef`). REMEDIATION IS PART OF THE GATE (#2778): the failure output names its own remedy, because a gate that states a requirement and withholds the means of satisfying it is a maintainer round-trip, not a gate — ADR-2719 §3's \"conspicuous declaration\" only works if the contributor can discover how to make it. Both failing branches name the commit trailer to add — `Emitted-Drift-Ack-Hash:` or `Emitted-Drift-Ack-Growth:` (ADR-3942) — print its exact grammar (`<key> — <reason>`, key and reason split on the FIRST em dash), and repeat \"do NOT regenerate anything\" — post-#2724 there is nothing left to regenerate, and hunting for a deleted baseline is the predictable wrong guess. The two branches key on DIFFERENT, now STRUCTURALLY DISTINCT trailer key spaces (separate maps since ADR-3942, closing a latent defect where a growth key could satisfy a hash lookup by naming coincidence and vice versa) and each says which: the hash pass keys on the EMITTED PATH (always contains a `/`, `Emitted-Drift-Ack-Hash:`), the size ratchet keys on the BARE FILENAME (`Emitted-Drift-Ack-Growth:`; `currentSizes` writes `sizes[entry.name]` from readdirSync over `msd-core/workflows/` + `agents/`). A stale-ack failure additionally says to drop the trailer line (amending the commit) when removing its last entry, since a lingering unused trailer signals nothing; post-#2789 it also offers CORRECTING the reason to name the ripple actually made, which is the other honest resolution and the one a contributor usually wants. NOT ack-able and deliberately given no ack text: the `NEW_FILE_CAP` branch, whose remedy is extraction. Text is sourced from one frozen `REMEDIATION` export in tests/helpers/emitted-diff.cjs, whose example line is rendered via `renderAckTrailer` (`<name>: <key> — <reason>`, ADR-3942) so the taught grammar cannot drift from what `parseAckTrailers` actually accepts (a round-trip test feeds the printed line back through the parser); a key that is reserved (`__proto__`/`constructor`/`prototype`) or contains `<`, `>`, or whitespace is rejected loudly, and a doc example like `<emitted/path> — <reason>` must never parse as a real declaration. Note the ADR's Consequences originally called the #2724 migration \"terminal\"; #2778 corrected that — it is terminal only for a PR that grows no shipped file. The ack was PR-lifetime data kept in permanent, shared, merge-path state, and each fix generated the next defect until ADR-3942 moved it off the tree entirely (see `### Emitted Artifact Provenance`): the single shared `tests/emitted-drift-ack.json` was a guaranteed merge-conflict cell (#2789; 5 of 6 conflicting PRs in one open queue collided on it and nothing else); #2914 replaced it with per-PR fragments under `tests/emitted-drift-acks/` — the `.changeset/` shape — ending the FILE conflict but not the KEY conflict, since two sources could never name the same path; #3078 found a fully-spent fragment left on `next` still walled off every key it owned (measured at the sweep: 45 fragments owning 403 paths, up from 13/272 at triage 19 days earlier) and added the post-merge-only `guard-no-ack-on-next` job plus a manual sweep; #3842's hand sweep handed three in-flight external PRs a `modify/delete` conflict each; #3823's hand-authored sweep, computed at branch time against a guard that evaluates at merge time, lost the race to a fragment merged mid-flight and left `next` red for 24 consecutive pushes; #3875's timed sweeper workflow automated the remedy but could not merge its own PRs (three independent, deterministic defects — bad conventional-title match, wrong CI-lane classification, no auto-merge path). ADR-3942 ends the chain: the escape hatch is now a commit trailer scoped to the PR's own commits, so there is no shared file, no shared key namespace, and nothing to sweep — the fragment directory, the next-lane guard job, the scheduled sweep workflow and the standalone ack linter are all DELETED (named by ROLE rather than by filename on purpose: a backticked path here asserts a LIVE repo path and `check-glossary-refs.cjs` fails on one that does not exist, while `lint-removed-but-needed.cjs` additionally fails on a deleted file's bare BASENAME appearing anywhere it scans — and this predicate's generated projection lands in docs/, which it does scan. ADR-3942 carries the exact paths; it sits under docs/adr/, which that guard exempts as a historical record). cf `RULESET.WORKFLOW_SIZE_BUDGET`, `RULESET.AGENT_SIZE_BUDGET`; see `### Emitted Artifact Provenance`"

Required: a closed-loop test that (a) drives the REAL end-to-end surface — not the pure core alone, since composition bugs live between surfaces — for N >= 2x the loop's window, (b) asserts convergence on the known-true value, (c) asserts the fixed point (an already-correct history must produce NO correction), and (d) asserts boundedness under an adversarial/oscillating history. Two defects shipped past a green ~26,800-test suite in epic #1952 for want of exactly this: calibration applied twice across two surfaces (factor^2, #2631) and calibration measured against its own corrected output so it oscillated to ~1.41 instead of converging on 2.0 (#2632). Every unit, boundary, property and round-trip test passed for both. HOW TO SPOT ONE (the detection tell, not a judgment call): the feature's own acceptance criterion carries a TEMPORAL QUANTIFIER — \"after N phases\", \"subsequent\", \"over time\", \"improves\", \"learns\", \"adapts\". That phrasing means the claim is about a TRAJECTORY, so a step-wise `given X return Y` test does not test the claim that was made. #1952's AC4 read \"After N phases, the error is computed and applied as a correction to SUBSEQUENT estimates\" — the tell was in plain sight and was still tested as a point. Survey of this repo (2026-07): estimation calibration is the ONLY true instance; size/mutation ratchets are exempt because they fail on both growth AND shrinkage (cannot self-satisfy), and retry ladders (node_repair_budget, plan_bounce_passes, provider_escalation) terminate rather than feed back.

PR #3577 fix: revert config-ensure-section dispatch to CJS cmdConfigEnsureSection (SDK author wrote single-section semantics under a name whose legacy callers expect full-default config init); plus 3 SDK parity carve-outs (configNewProject defaults align with sdk/shared/config-defaults.manifest.json, return relative .planning/config.json path, drop quotes from Unknown config key, lead malformed-JSON error with \"Failed to read config.json:\"). PR #3649 fix: chunk node --test spawn at 28K argv ceiling (Windows CreateProcess lpCommandLine cap 32,767 was instantly aborting unchunked spawn of 546 paths). Chunking fix surfaced 14 pre-existing Windows-only test bugs (4010 pass / 14 fail; vs 0/0 before — entire suite was un-runnable on Windows).
