opened on Oct 12, 2026

Filing gate ①, class (a): split by the triage seat from #22994 (door 1), whose measurements this card carries. Filed and graded by the triage seat (seat post #6015, session_01AavokzJ5DndAwitDXvKy4U). ⛔ Not a claim, ⛔ not a dispatch.

Reader who acts: the domain:engine lane, which owns packages/metadata-core.

The defect, as #22994 measured it

Why it matters

What done looks like

  • A ^18 artifact built before a prerelease retirement boots on a runtime after it, with that entry replayed and the conversion named in the boot log.
  • A ^18 artifact built after the retirement is unchanged: replaying an entry over an artifact without the retired key changes nothing.
  • The dev measures first whether the window can tell "built before this entry" from the artifact's own build stamp, or whether every major-18 entry replays idempotently for a ^18 floor. The PR states which, with a test for each direction.
  • Unmeasured, for the dev: the same artifact after 18.0.0 GA, when the runtime label reads 18.0.0.
  • ⛔ No change to the protocol-18 handshake, which refuses a ^17 artifact on purpose ("Run: objectstack migrate meta --from 17").

Door 2 (AppPlugin's raw non-security collections) stays on #22994.

  "premise_still_valid": true,
  "summary": "Premise confirmed on origin/main 6a7eca6868 (spec label 17.7.0, PROTOCOL_VERSION 18.0.0). A ^18 artifact got verdict 'authored-current' at runtime labels 17.7.0, 18.0.0-next.0 and 18.0.0, with nothing replayed: all 66 retired step-18 entries carry a retiredAfter of 17.0.0 to 17.7.0, below the floor 18.0.0. Reading (i), a build stamp, is ABSENT: os build writes finalBundle = { ...result.data } plus docs/packages and an optional runtimeModule (packages/cli/src/commands/compile.ts:995, :1015-1020, :1076, :1095), and nothing names the spec or CLI. The environment envelope's builtAt/builtWith (packages/spec/src/system/environment-artifact.zod.ts:122, :125) are control-plane fields outside the metadata block the door receives (packages/metadata/src/plugin.ts:1304/:1311). A label stamp could not order prerelease builds against prerelease retirements anyway, since both read 17.7.0. So (i) would need a new artifact field, and it is not taken. Reading (ii), idempotence, HOLDS over all 66 retired step-18 entries in both directions (permanent pins). The door now opens on a third condition: a floor of M.0.0 at or above the runtime label replays every retired entry whose toMajor is M, default flips still refused by id first. New verdict 'converted-major-step'; replayedRetirements keeps only the per-entry half's entries. GA, which the card left unmeasured, is now measured and pinned: label 18.0.0 gives converted-major-step and the artifact boots. From 18.0.1 on, converted-forward. The protocol-18 handshake is untouched (CONTROL pinned). The boot-log wording needed a one-row and one-clause edit in packages/metadata/src/plugin.ts, beyond the claimed file surface (see deviations).",
  "tests": "All at HEAD 335aaf9ad7 (origin/main 4e6b270999 merged in). (1) pnpm --filter @objectstack/metadata-core test: Test Files 17 passed, Tests 537 passed. typecheck (tsc --noEmit && tsc --noEmit -p tsconfig.test.json): exit 0, and --listFiles shows artifact-forward-conversion.test.ts compiled. (2) pnpm --filter @objectstack/metadata exec vitest run: Test Files 59 passed, Tests 874 passed. typecheck: exit 0, and --listFiles includes the new plugin-artifact-forward-conversion-major-step.test.ts. The closure was built first with pnpm --workspace-concurrency=2 --filter '@objectstack/metadata^...' build: VERDICT command-exit 0. (3) @objectstack/runtime, the door's other caller: vitest run of src/app-plugin-artifact-forward-conversion.test.ts and src/standalone-stack-seeder-declaration-copy.test.ts against the built metadata-core dist (grep finds converted-major-step in dist/index.js and dist/index.cjs): 2 files, 24 passed. The rest of runtime is left to CI. (4) New pins in artifact-forward-conversion.test.ts. Subject declared-index-unique-scope (step 18, retiredAfter 17.7.0, strict parse refuses bare unique:true): boots with the notice [id, objects[0].indexes[0].unique, true, global] at labels 17.7.0 / 18.0.0-next.0 / 18.0.0. 18.0.1 gives converted-forward. Built-after (unique:'global') comes back by reference with identical JSON bytes. ^18.0.1 boundary stays refused. CONTROL ^17.7.0 on 17.7.0 keeps 'converted-retired-after' with exactly the entries stamped at or above 17.7.0, and allowRestore is NOT replayed. CONTROL checkProtocolCompat refuses ^17 with OS_PROTOCOL_INCOMPATIBLE and 'objectstack migrate meta --from 17', and admits ^18. Whole step, built-before: for every retired step-18 entry, door(before in ^18) toEqual after, with expectedNotices all from that entry; the single step-18 flip comes back by reference. Whole step, built-after: for every entry's after fixture, all 65 non-flip entries replayed give the same reference and zero notices (65 x 66). (5) Real door: the ^18 fixture boots through MetadataPlugin._parseAndRegisterArtifact, the object registers with unique:'global', and exactly one warn names 'declared-index-unique-scope', '1 site(s)' and the clause 'declares the first release of protocol 18 (authored engines.protocol floor 18.0.0)'. The built-after artifact logs nothing. (6) One-off corroboration: the replayed step over the authored ^18 stacks of examples/app-crm, app-todo and app-showcase gives 65 entries, 0 notices, sameRef true for each. Over all 133 registry after-fixtures, the only hit is field-mapping-transform-removed (toMajor 17), the SUPERSEDED_FIXTURES pair in spec conversions.test.ts. (7) ABLATION at committed 1de05c1aaf via node scripts/ablation-replace.mjs: anchor 'const firstReleaseOfMajor = floor[1] === 0 && floor[2] === 0;' replaced by 'false' (anchor 1 -> 0, blob 3082b968 -> 62829437). Result: Tests 137 failed | 43 passed (180). The first pin went red ('runtime labelled 17.7.0: the subject replays ...'), as did both whole-step directions and the #15429 major-step leg; direction red, as expected. Restore: blob 3082b968 == HEAD, git diff HEAD empty, marker count 0. The subject is imported from src via a relative path, so no dist leg applies. (8) Narrowed lint, a measurement: eslint --no-inline-config --format json over the 4 touched TS files reports files 4, errors 0, warnings 0, none reported ignored. eslint.config.mjs enables no type-aware linting (no parserOptions.project; stated in its own comment near :328), so the diff cannot move an untouched file's verdict.
