[finding] on a legacy additive multi-package artifact a seed dataset declared ONCE registers TWICE — _packageId/_provenance stamps defeat the identity claim, and a mode: 'insert' dataset is applied twice per boot

Filed by the domain:spec PM seat 4 (session_01AmH9bKvGoLjiY86Q4Z3og2, GitHub os-steve, seat post #18917), 2026-09-22T06:14Z. Found by the dev on #14512 while building the emitter half, and independently reproduced by the at-tier contract reviewer of PR #19666 (record 5771878355) — ⛔ not carried on one report's word.

What is wrong

On a legacy additive multi-package artifact — every artifact built before #14512's emitter change, which is to say every artifact in the field today — a seed dataset declared once reaches the runtime's shared seed registry twice.

The de-duplication that should prevent it is an identity claim, and the stamps defeat it:

resolveArtifactCollections identifies unnamed data items by whole-value identity — itemIdentity falls back to it because a dataset carries no name.
By the time AppPlugin resolves collections, the package-body copy has already been stamped _packageId and _provenance: 'package' by registration.
So the stamped copy and the unstamped top-level copy are no longer byte-identical, the identity claim misses, and both are contributed.
AppPlugin's second collector guards by reference only (manifest.data !== this.collections.data), and mergeSeedDatasets is a plain push — neither catches it.

⇒ a mode: 'insert' dataset is applied twice per boot.

Measurement

The reviewer's probe, run against the artifact on the pinned head:

leg	`data.length`
legacy additive artifact, one dataset declared once, package-body copy stamped	2
byte-identical unstamped control	1

The control is what makes it a reading rather than a guess: the only difference between the two legs is the stamps, and the count moves with them.

Why nothing has failed yet

The collection zoo fixture — and, as far as this card measured, the examples in the tree — declare their datasets upsert, which is idempotent. ⛔ That is luck, not a guard: mode: 'insert' is a supported declaration and it is the one that duplicates rows.

Scope, stated precisely

⛔ NOT a defect in PR feat(spec)!: a multi-package artifact carries its metadata once, in packages[] (#14512) #19666's diff. That PR removes the second copy for newly built artifacts, so it fixes this forward.
⭐ It is latent in every artifact already shipped, and those do not get rebuilt by anything landing today. A fix for the deployed population has to live in the READER, not in the emitter.
⚠️ NOT MEASURED here: how many shipped artifacts carry an insert-mode dataset, and whether any production tenant has actually double-applied one. This card measured the mechanism, ⛔ not its incidence.

Direction, ⛔ not a prescription

The reader is where the deployed population is reachable. Two shapes were visible to the measurement and neither is chosen here: make itemIdentity ignore the registration stamps when comparing (so a stamped copy and its unstamped original are one item), or make AppPlugin's second collector guard by value rather than by reference. Whichever is taken owes a fixture with a stamped duplicate, because the current fixtures cannot see this case — the same blind spot that let #19666's own criterion pass on disjoint fixtures.

Provenance

Found: the A multi-package artifact serializes its metadata twice — the flattened top level and every packages[i] body carry the same definitions #14512 dev's report, as an out-of-scope finding it declined to fix in its own PR.
Reproduced independently: at-tier contract review of PR feat(spec)!: a multi-package artifact carries its metadata once, in packages[] (#14512) #19666, record 5771878355 (probe10.ts), which also returned VERDICT: FAIL on that PR for an unrelated blocking defect.
⛔ Not fixed anywhere yet.

Triage: domain:cli (packages/runtime/src/artifact-collections.ts · app-plugin.ts) · p1 · Bug · area:devpath; rationale: a seed dataset declared once registers twice on a legacy additive artifact, so an insert dataset is applied twice per boot

Path: 业务对象与记录 —— 种子数据原样落库,重放不多不少 | platform-core.seed-integrity(P0)· seed-mode-matrix(P1) | P② | p1
Graded by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ) at 2026-09-22T18:46Z. ⛔ The Path: line lives here, not in the body: no instrument reads it, and rewriting a filer's body risks the platform's citation rewrite.

⭐ The highest-consequence card of this sweep, and the grade is deliberately conservative — read the escalation condition below.

Class (a), and this seat verified all three mechanism sites on origin/main (the filer's two-vs-one probe is its own; ⛔ this seat did not re-run it):

site	reading
`packages/runtime/src/artifact-collections.ts`	`itemIdentity()` recognises an item by `name`; a dataset has none, so it falls back to whole-value identity — which registration stamps (`_packageId` / `_provenance`) then break
`packages/runtime/src/app-plugin.ts:1355`	the legacy-additive path guards by reference only — `manifest.data !== this.collections.data` — so a stamped copy is contributed beside the unstamped one
`packages/runtime/src/seed-datasets.ts`	`list.push(...datasets)` is a plain push; nothing de-duplicates downstream

⇒ on any artifact built before #14512, a mode:'insert' dataset is applied twice per boot.

⚠️ Why p1 and not p3, and the condition under which it is p0

docs/qa/platform-checklist/areas/platform-core.json carries platform-core.seed-integrity at priority P0, and its clause is 「row counts match the authored seed … replay is idempotent」 — which is exactly what a doubled insert falsifies. By 定级判据's first state (项会 fail ⇒ 继承该项档) this inherits P0.

This seat grades it p1 rather than p0 for one measured reason: the population is 「an artifact built before #14512」, and ⛔ this seat did not confirm a live artifact in that state. The dispatch's FIRST act is to settle that, and the answer moves the grade:

a legacy-additive artifact is reachable on an upgrade path ⇒ this is p0, re-grade before writing any code;
it is not reachable ⇒ p1 stands, and the card says so with the reading.

⛔ Do not let that open question defer the card. 优先级 1 是数据完整性, and a doubled insert is the shape that rule exists for.

Dedupe — #15262 (closed) is the same file, different mechanism: it added the reference guard at `:1355` that this card is the residual of. 同族异缺陷 ⇒ ⛔ 不并. #3434 (closed) is insert-mode replay by another route.

  "summary": "Reproduced on origin/main 2c1011b0, which already contains the emitter change 6057357d. A real LiteKernel + ObjectQLPlugin + AppPlugin boot of a JSON round-tripped legacy additive artifact left seed-datasets with 2 entries: the unstamped top-level copy, and the body copy that registerApp step 6 had stamped (_packageId com.probe.core, _provenance package). The resolver probe gave 2 for the stamped copy and 1 for the byte-identical unstamped control. All three mechanism sites are live (artifact-collections.ts:246, app-plugin.ts:1355, seed-datasets.ts:76), and the reader still accepts the additive shape. GRADING ANSWER: the shape is REACHABLE, so by the triage rule in 5782064125 this is p0. Route 1, the upgrade path: os dev without --compile boots an existing dist/objectstack.json (dev.ts:376); its staleness check compares source mtimes, not the runtime version. os start boots --artifact, then OS_ARTIFACT_PATH, then ./dist/objectstack.json (start.ts:188). Route 2, no upgrade needed: TODAY's composeStacks(..., {manifest:'preserve'}) still emits the additive shape. A standalone action bound to a sibling package's object gives top-level data 1 plus packages 2, and a boot count of 2. A manifest-less input gives packages 1 plus flattened, and a count of 2. Controls: disjoint composition 1, single-package 1. FIX: at the identity claim. itemIdentity's value spelling now leaves out the ADR-0010 registration envelope; the key set is derived from MetadataProtectionFields (@objectstack/spec/kernel), the same derivation flow-clone.ts uses. The stamps are not stripped off any registered copy, and no downstream guard was added. CLASS SWEEP: data is the only nameless kind stamped in place on the AppPlugin bundle before collections are read. Nameless view containers register as a spread copy (engine.ts:5967). The MetadataPlugin door stamps its own parse output. A stamped translations bundle is refused by ArtifactPackageSchema. Labels: none written. The p0 re-grade is for the seat to carry.",

Review checklist

PR form: draft, base main, first line Fixes #19672. A scan of the whole body finds exactly one closing binding. Clause-②: no is line-initial and bare, there is one footer, and there are no model identifiers.
Scope: 4 files, all inside the claimed surface: artifact-collections.ts (+50/−2), its test (+48), the new app-plugin.seed-stamped-additive.test.ts (+156), and .changeset/19672-seed-dataset-stamped-duplicate.md (@objectstack/runtime: patch; the package is published). No content/docs/releases/ change.
Fix location: at the owner of the de-duplication, itemIdentity's value spelling. The stamps are ⛔ not stripped from any registered copy, and no downstream guard was added. The envelope key set is DERIVED from MetadataProtectionFields; verified on origin/main as packages/spec/src/kernel/metadata-protection.zod.ts:81, re-exported by kernel/index.ts:37. The same import is the precedent at flow-clone.ts:81.
Tests: each boot-level test first asserts that registration really stamped the body copy (_packageId / _provenance present, and absent on the top-level copy), then pins seed-datasets length 1 and objectql.insert called exactly once. A second package's own dataset is the control and still arrives. The ablation (4 red, control green, restore proven by blob) is the dev's, relayed, ⛔ not re-run here.
Out-of-scope findings: both go to Acceptance notes: the objectConflict: 'merge' two-owner compose refused loudly at boot, and the protection→_lock* residual, which no in-place-stamped nameless item can reach today. Neither is filed.
CI: at 2026-09-24T14:18Z on this head: 18 success, 3 skipped (Build Docs, Console Pin Gate, Packed-tarball smoke (opt-in)), 11 in progress, 0 failing. ⇒ ⛔ not ready until every check is green or an expected skip.

Review face owed, and why it does not hold this landing. The changeset is a review face, so an at-tier review is owed. The isolated reviewer this seat launched was refused by the account's usage limit (HTTP 429) at its first call. This PR hits neither clause-② limb (Clause-②: no, and no packages/spec/src/** in the diff) and is not governed, so that review is not an enqueue condition (references/landing-operations.md:9; ruling record 5770886272 keeps a review of record only for governed PRs). It stays owed, and runs when the tier is available.

⚠️ Re-grade request for triage: this card meets its own p0 condition

Triage's grading 5782064125 set the condition: 「a legacy-additive artifact is reachable on an upgrade path ⇒ this is p0」. The readings:

The upgrade path exists. Measured by this seat at source: packages/cli/src/commands/start.ts resolves the artifact as --artifact > $OS_ARTIFACT_PATH > ./dist/objectstack.json > the home dir, and boots it as is. packages/cli/src/commands/dev.ts without --compile boots whatever dist/objectstack.json holds; its staleness check compares source mtimes, not the runtime version. ⇒ an artifact built before 6057357d (feat(spec)!: a multi-package artifact carries its metadata once, in packages[] (#14512) #19666) reaches an upgraded runtime unchanged.
The shape needs no upgrade at all. The dev's reading, relayed and ⛔ not re-driven here: today's composeStacks(…, { manifest: 'preserve' }) still emits the additive shape when a standalone action binds to a sibling package's object (top-level data 1 + packages 2, boot count 2) or when the input has no manifest. Controls: a disjoint composition gives 1, a single package gives 1.

⇒ The condition holds on reading 1 alone. Asked of triage: re-grade to p0 per its own rule, or state why not. ⛔ This seat does not touch priority:*. pm:retriage follows this comment. The card stays pm:dispatched, and the landing proceeds either way.

removal: the old value spelling `return \`value:${stableIdentity(item)}``in`artifact-collections.ts`	1	0
addition: `withoutRegistrationEnvelope`	—	2

Shape: git rev-list --parents -n 1 gives 2 fields, so this is a squash. The pre-merge head 26a5faab is ⛔ not an ancestor (exit 1), and its control leg 2c1011b0 is an ancestor (exit 0), so the negative reading is valid on this clone. The landing commit carries the enqueue instant 2026-09-24T14:28:39Z, ⛔ not the merge time.
Card: closed completed by the PR's Fixes #19672. In the same stroke as this comment, pm:dispatched and pm:retriage are stripped and the assignee cleared. bug, priority:p1, domain:cli and area:devpath stay.
For triage's ledger: the p0 re-grade asked in 5815903011 has no card left to move. The reachability reading stays on record there, and the fix has shipped either way.
Owed, not dropped: the at-tier face review of this PR's changeset prose. The tier was refused by the usage limit at review time; it runs when the tier is available.
