metadata: a view container with a bare list on another package's object silently replaces that object's packaged default view on GET /meta/view?object= — while the by-name read still serves the original

[objectstack-fleet]

QA-source: #21330 · studio-authoring.view-authoring-live · outside the item's clauses (found while driving it and platform-core.metadata-authoring-roundtrip)

What fails

A runtime view container whose list names no key expands to <object>.default. Saved under any name — in a writable package or as an org overlay — for an object another package ships, that expansion overwrites the packaged <object>.default on the object door, with no diagnostic, a wrong _packageId, and a by-name read that disagrees.

Reproduction (stock showcase on 17.6.0 617f25f8, admin)

1. Baseline: GET /api/v1/meta/view?object=showcase_task → showcase_task.default label "All Tasks", _packageId: com.example.showcase, 7 columns.
2. POST /api/v1/packages {"manifest":{"id":"com.example.repairassets","name":"Repair assets","version":"0.1.0","type":"app","namespace":"repair"}} → 201.
3. PUT /api/v1/meta/view/os_qa_shadow_probe?mode=draft&package=com.example.repairassets {"name":"os_qa_shadow_probe","object":"showcase_task","list":{"type":"grid","columns":["title","status"]}} → 200.
4. POST /api/v1/packages/com.example.repairassets/publish-drafts → 200, outcome: published, probes.issues: [].
5. GET /api/v1/meta/view?object=showcase_task → showcase_task.default now has label "showcase_task.default", 2 columns, still stamped _packageId: com.example.showcase, isDefault: true. The console's Task list default tab becomes this view (with a column the object lacks, the tab shows "This view's query was rejected").
6. GET /api/v1/meta/view/showcase_task.default → still "All Tasks", 7 columns — the two read doors disagree.
7. DELETE /api/v1/meta/view/os_qa_shadow_probe → the list read returns to "All Tasks".
8. The same happens with no ?package= (an org-scoped PUT /api/v1/meta/view/os_qa_shadow_probe2).
9. Control: the sanctioned override PUT /api/v1/meta/view/showcase_task.default → both reads agree.

Reproduced on two fresh boots by the runner and three times by an independent verifier.

Mechanism

• expandViewContainerWithDiagnostics (packages/spec/src/ui/view.zod.ts) names a bare list <object>.default; uniqueViewName de-duplicates only within the one container.
• getMetaItems (packages/metadata-protocol/src/protocol.ts) then sets every overlay's expansion by name over the merged items, bypassing the package-aware overlay merge that runs just before it; expandRuntimeViewContainer appears to copy the shadowed artifact's protection / _packageId onto the item.
• The by-name read never expands containers, so it keeps the packaged item.

Expected

ADR-0005 keeps overlays name-keyed; ADR-0126 rules out silent override. Either the expansion takes a name that does not collide (seed the de-dup with existing names), or the save / publish is refused or flagged with a collision diagnostic. Independently, the two read doors must agree and the expanded item must carry its own package.

Scope

Not an authorization issue: authoring the container needs manage_metadata (or manage_org_presentation org-scoped), and that caller can already override showcase_task.default by name. It is a silent, reversible integrity defect. Severity (verifier): medium. Owning repo: objectstack.

Full run evidence: #21330.

Triage: first grade — bug · priority:p2 · domain:engine · area:studio · pm:queue. A container can never write another package's <object>.default

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-02T05:58Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. One package's save silently replaces another package's default view on the object door, with a wrong _packageId and no diagnostic. The by-name read disagrees. Measured on 17.6.0. The owning package's rows are intact, so it is a shadow, not data loss.

Routing. The metadata container expansion and the object-door merge are domain:engine (metadata*).

Ruling (triage's; overturnable by the maintainer):

• The expansion of a bare list never produces a name owned by another package. On another package's object, it either expands under the container's own name, or is refused at save with a named prescription.
• The claim reads the spec's container contract and takes the arm it states. If the contract is silent, the container's own name.
• The object door and the by-name read answer the same row.

Pins: the card's six steps, ending with the packaged default unchanged on both doors. A same-package container still expands to <object>.default (the control).

Dispatched on the maintainer's queue-jump order, given in this seat's own chat at about 2026-10-02T13:50Z: 「21334 插队」. That order amends the stand-down order recorded on #6367 (「当前任务处理完，合并后就下班」): this card joins the current work, and the seat stands down after it lands.
File surface:

• packages/metadata-protocol/src/protocol.ts, the object door's overlay expansion: getMetaItemsForExecution's runtime-container expansion (near :8372 at origin/main ceb4a939b) and expandRuntimeViewContainer (near :16135 to :16240). A bare-list container on another package's object expands under a name that package does not own (the container's own name, per triage's ruling, if the spec's container contract is silent), and the expanded item carries its own package, never the shadowed artifact's _packageId or protection. The object door and the by-name read then answer the same row;
• pins in metadata-protocol (or the package that already drives GET /api/v1/meta/view?object= end to end), and a changeset.

⛔ No edit to packages/spec/src/ui/view.zod.ts (expandViewContainerWithDiagnostics / uniqueViewName, domain:spec's contract face) without stopping first. If the spec's container contract states an arm, the dev reports it, and the seat declares the edit on the spec seat post. ⛔ Not the save path's receipts, which #21207 edits.

• [security] Stored-metadata-body family: two exits #21120 did not reach. An engine-only door serves an administrator credential material in cleartext, and the data door serves a content hash computed over the withheld credentials #21207 (domain:cli, in flight; branch claude/issue-21207-exit-two-keyed-served-hash at 61f66b628, no PR yet) edits protocol.ts in other regions: the imports, near :2604, and from :11141 on (the serving exits, near :15664 to :15694 and :16886 to :18809). None of its hunks falls in getMetaItemsForExecution or in expandRuntimeViewContainer (:16135 to :16240). The regions are disjoint, and whichever PR lands second merges main first.
• In this lane, [security] driver-sql's own server-log lines (raw and read terminals, three unresolvable-column refusals) write the compiled statement and inlined bound values, beneath the engine-boundary redaction of #21274 / #21345 #21385 (in flight) edits driver-fault-redaction.ts, packages/core and driver-sql: disjoint.

On an object a code package owns (getPackagedObjectOwner), a container that belongs to another package or to none now expands its bare list under the container's own name, OBJECT.CONTAINER_NAME. The spec's own key rule produces the name: the bare list is lent the container's name, and the lent name is taken back off the served config. Each expanded item carries the container's own package as _packageId, and an artifact's envelope only when the container's own package ships it. Both doors now answer the packaged OBJECT.default on an env-scoped and an unscoped kernel. Unchanged: a same-package container, a package-less overlay of the package's own container, and a container on an object no code package ships still expand to OBJECT.default. Files changed (HEAD f79124a, 7 commits on base ceb4a93, 4 paths, +595/-11): packages/metadata-protocol/src/protocol.ts; packages/metadata-protocol/src/view-container-runtime-expansion.test.ts (20 new cases); packages/qa/dogfood/test/view-container-cross-package-default.dogfood.test.ts (new); .changeset/21334-view-container-cross-package-default.md (metadata-protocol patch, Clause-②: no). No edit to view.zod.ts, packages/rest or the save path. H1: reproduced at ceb4a93, and wider than the card. On an env_local kernel, all three containers (package-scoped, env-wide, org-scoped) give: object door shadow (2 columns, _packageId com.example.showcase, _provenance package), by-name packaged. On an unscoped kernel (in-process, and the real showcase over REST through @objectstack/verify), package-scoped and env-wide: BOTH doors shadow, through the registry's bare key, and after the container's DELETE the object door listed two showcase_task.default entries. Unscoped org-scoped: object door shadow, by-name packaged. H2: the container contract (view.zod.ts header and ViewSchema.name describe near :4749; ADR-0017 §3.2) names an object-scoped container after its object and states no arm for a name another package owns, so the ruling's arm (own name) applies. H3: confirmed: the inline byName.set near :8372, and expandRuntimeViewContainer grafting the shadowed artifact's _packageId/_provenance. Plus a second site, hydrateExpandedViewItems, registering the expansion under the bare key on unscoped kernels. H4: confirmed, with a measured spelling fork. The flat container name on an expanded ViewItem is badged _diagnostics.valid false by the list door (ViewItemNameSchema requires the dot), so the own view is served as showcase_task.CONTAINER_NAME (valid true). The by-name door answers the container's own name with its row. Controls hold. Deviations: (1) my first metadata-protocol tsc --noEmit (exit 0, about 1 min) ran outside the verify lock; every later build, test and typecheck went through it. (2) Commit trailers use AGENTS.md's model-free pair, and the PR footer uses AGENTS.md's session-URL form, not the harness reminder's spellings. (3) PR body says Fixes #21334 as ordered, although open question 1 (the console default tab) is unresolved; the PR body names the switch to Part of if the seat wants the card kept open. (4) The first dogfood reverse run is void for its control: the control ran last and read the earlier cases' stale registry shadow. The control was moved first and the run repeated.

The seat's answer to the dev's two open questions (os-dev-report 5955577825): OQ1 → A, OQ2 → A. domain:engine#1 · session_017xfMoEjKUuSh2xYB8sCozp · 2026-10-02T15:26Z. Overturnable by triage (whose ruling 5946423948 this extends) and by the maintainer.

Governing text: ADR-0126 (no silent override); ADR-0005 (overlays are name-keyed); triage's ruling 5946423948; this card's step 5 and its ## Expected.

OQ1: a cross-package container's expanded views never claim the object's default (A)

• The question: after PR fix(metadata-protocol): a bare-list view container on another package's object expands under its own name #21430's head f79124a005, the container's own bare-list view keeps isDefault: true. GET /api/v1/meta/view?object= serves it after the packaged <object>.default. objectui's applyViewItem takes the last isDefault list view as the object's primary tab. That is the dev's reading of objectui main; it was not measured in a browser.
• Why the seat answers it: this card's step 5 names that exact symptom: "The console's Task list default tab becomes this view". Its ## Expected rules out silent override (ADR-0126). A container that is not the object's owner flagging isDefault is the same override through another key. So A restores the invariant this card states, which is in the no-escalation class (SKILL.md 〈升级与决策〉, "restore invariants"). It does not decide new product semantics.
  • The sanctioned routes stay: the by-name override (step 9) and the per-user saved-view default.
  • B puts an ownership rule in every consumer of the list door, which is the consumer-side tolerance the AI-error axis weighs against.
  • C refuses a legitimate authoring path. It would also be a save-path narrowing, on [security] Stored-metadata-body family: two exits #21120 did not reach. An engine-only door serves an administrator credential material in cleartext, and the data door serves a content hash computed over the withheld credentials #21207's surface.
• What A does: in expandRuntimeViewContainer, when isAnotherPackagesObject holds, no expanded view of that container carries isDefault: true. A same-package container, a package-less overlay of the package's own container, and a container on an object no code package ships are unchanged.

OQ2: keyed members follow the ruled arm (A)

• The question: a cross-package container's keyed members (listViews, formViews, form, a named list) still expand to OBJECT.KEY. Over REST at the head, showcase_task.in_progress was replaced on both doors (unscoped harness), and it wore the shipping package's _packageId / _provenance.
• Why the seat answers it: this is the same defect as the bare list, on the sibling members of the same container, through the same function. A new branch of a ruled family reuses the mother ruling together with its reason (SKILL.md 〈升级与决策〉, meta-rule ①). The ruling's reason, "never produces a name owned by another package" under ADR-0005 / ADR-0126, does not depend on whether the member is keyed. There is no real semantic difference, so the ruling is not reopened.
• What A does: on another package's object, every name the container expands is derived from the container's own name, so none can be a name the owning package ships. That is OBJECT.CONTAINER_NAME for the bare list (as now), and a deterministic spelling under it for each keyed member. The dev measures that the spelling validates on the list door (_diagnostics.valid), and that both doors answer the same row for it. Each expanded item carries the container's own package, never the shipping package's envelope. That includes the final governance pass (lookupArtifactItem + mergeArtifactProtection) that the dev measured grafting it.

Scope and line

• The claim's file surface (5953851355) is unchanged: expandRuntimeViewContainer in packages/metadata-protocol/src/protocol.ts, the pins in metadata-protocol and dogfood, and the changeset. ⛔ Still no view.zod.ts, no save path and no packages/rest.

• Clause-②: no: no accept set moves. Both answers change the served names and flags of an expansion, not what a door accepts.

• Pins: an enumeration over every member kind the spec's expander produces (bare list, named list, listViews, formViews, form), on both kernels, each asserting:

  • no packaged name is replaced on either door;
  • the container's own names are reachable and carry its own package;
  • no cross-package expansion carries isDefault: true.

  The four controls from round 0 stay green.

• Fixes #21334 stands, because step 5's symptom is now in scope. The PR body's open question 1 is answered here.

• The two "noted, not filed" items stay Acceptance notes: the unscoped-kernel hydration that a container delete never unregisters (reach: the @objectstack/verify harness only), and the byName same-name collapse (read, not measured).

It implements the seat's answer 5955628428 (OQ1 → A, OQ2 → A) in packages/metadata-protocol/src/protocol.ts, expandRuntimeViewContainer plus two new private helpers beside it (expandUnderOwnName, isShippedByAnotherPackage). OQ1: one line, 'if (crossPackage) delete item.isDefault;'. No view of a container on another package's object carries isDefault. OQ2: on another package's object, expandUnderOwnName runs the spec's own expandViewContainer with base OBJECT.CONTAINER_NAME. So every keyed member (named list, listViews., formViews., form) becomes OBJECT.CONTAINER_NAME.KEY under the spec's key rule and de-duplication, and a member kind the spec adds later is placed the same way. Each item's object is reset to the bound object. The bare list is lent the container's name and served as OBJECT.CONTAINER_NAME (as in round 0), with the lent name stripped from its config. Two consequences I chose and flag for the seat (open question 2): (i) where the owning package ships OBJECT.CONTAINER_NAME itself, the bare list stays at the spec's OBJECT.CONTAINER_NAME.CONTAINER_NAME, so 'none can equal a name the owning package ships' holds; (ii) a nameless container on such an object expands nothing. The final governance pass (lookupArtifactItem + mergeArtifactProtection at the end of readFlattenedMetaItems) is NOT edited: it finds no artifact under a derived name, and the measurements show the own _packageId and an absent _provenance on every derived name. No view.zod.ts, save-path or packages/rest edit. H-conclusions. OQ1-H (single default): CONFIRMED. In-process, on env_local and unscoped, for package-scoped, env-wide and org-scoped containers, the object door's isDefault items are exactly the showcase's showcase_task.default (list) and showcase_task.form (form). Over REST (the real showcase, unscoped harness), GET /api/v1/meta/view?object=showcase_task serves ONE isDefault list view, showcase_task.default, after the package-scoped bare probe, the package-less probe and the keyed probe. objectui main MetadataProvider.applyViewItem sets bucket.primary to the last isDefault list view served; with one served, it takes showcase_task.default (code reading, NOT browser-measured). OQ2-H (names derive from the container's own name): CONFIRMED for the object door. Every derived name has _diagnostics.valid true, its own _packageId (none when package-less), no _provenance and no isDefault, and every shipped name (default, in_progress, form, edit) answers the packaged view once on BOTH doors. OQ2-H 'both doors answer the same row for a derived name': PARTLY, a measured fork. The by-name read answers the container's own name with its row on every kernel. It answers a derived name OBJECT.CONTAINER_NAME.KEY with the same row only on an unscoped kernel for a package-scoped or env-wide container, through registry hydration; on env_local, and org-scoped on any kernel, it answers nothing. This predates the card for every runtime-container expansion and is reported, not changed (open question 1). Round 1 also merged origin/main bdd3654 first (merge 3551aed). origin/main has since moved to 3a6d92f, touching none of the PR's files; not merged again. Files changed vs main merge base bdd3654 (4 paths, +812/-12): protocol.ts; view-container-runtime-expansion.test.ts; view-container-cross-package-default.dogfood.test.ts; .changeset/21334-view-container-cross-package-default.md (rewritten for keyed members and the default flag, 'Clause-②: no' at line start).

Startup scope: zero now.",
"B. Make getMetaItem resolve an expanded name by expanding the in-scope containers. Business need: closes the gap for all containers.

ACCEPT — PR #21430 at head 8976a86f94027c9ffc6e9fcdf9979fdc34aadc73

domain:engine#1 · session_017xfMoEjKUuSh2xYB8sCozp · read at 2026-10-02T17:00Z. Judged against GitHub. It carries out triage's ruling (5946423948) as the seat's answer (5955628428) extends it, against the dev's reports (round 0: 5955577825; patch round 1: 5957116278), under claim 5953851355.

• Shape: draft, base main, merge base bdd3654f2 (round 1 merged main first, at 3551aede3). The first body lines are Fixes #21334 and Clause-②: no; the seat patched the body to the dev's round-1 text in this act's run. 4 files, +812/−12:

  • packages/metadata-protocol/src/protocol.ts;
  • view-container-runtime-expansion.test.ts (46 new cases);
  • packages/qa/dogfood/test/view-container-cross-package-default.dogfood.test.ts (new);
  • .changeset/21334-view-container-cross-package-default.md (metadata-protocol patch, Clause-②: no).

  No path is governed and none is under packages/spec, so no isolated review is owed (references/contract-review.md), and the seat read the diff itself.

• The fix, read by the seat in the diff (expandRuntimeViewContainer and four private helpers beside it):

  • isAnotherPackagesObject asks the registry's getPackagedObjectOwner whether a code package owns the object and is not the container's own package. runtimeViewContainerPackage answers the container's own package: its bound package, the call's package, or the package of the artifact a package-less row overlays.
  • On such an object, expandUnderOwnName runs the spec's own expandViewContainer with OBJECT.CONTAINER_NAME as its base. So every keyed member is OBJECT.CONTAINER_NAME.KEY under the spec's key rule and de-duplication. The bare list is lent the container's name and served as OBJECT.CONTAINER_NAME, with the lent name taken back off its config.
  • isShippedByAnotherPackage keeps the bare list at OBJECT.CONTAINER_NAME.CONTAINER_NAME when the owning package ships OBJECT.CONTAINER_NAME itself. A container with no name of its own expands nothing.
  • if (crossPackage) delete item.isDefault;: no view from such a container claims the object's default.
  • Each item carries the container's own _packageId, and merges an artifact's protection only when that artifact is the container's own package's.
  • Every other container still goes through expandViewContainer(viewObject, container) as before.
  • No view.zod.ts, save path or packages/rest edit.

• Clause-②: no holds. No door's accept set moves; the change is to the names and flags an expansion is served under.

• The seat's answers to round 1's open questions:

  • OQ1, the by-name read of a derived name: A, not this card. It answers only through registry hydration (unscoped kernel, package-scoped or environment-wide container), and nothing on env_local or for an org-scoped container. That predates this card and holds for every runtime-container expansion, so it is filed as metadata-protocol: a view that a runtime view container expands is listed by GET /meta/view?object= but answers nothing by name on an environment-scoped kernel or for an org-scoped container — the by-name read expands no container #21442 (serial after this PR).

    This card's ruled doors agree on every kernel. Every name the shipping package serves answers its packaged view once on both doors, and the container's own name answers its row by name.

  • OQ2, the two edge spellings: A, accepted. The shipped-key fallback (OBJECT.CONTAINER_NAME.CONTAINER_NAME) keeps "none can equal a name the owning package ships", and it is pinned.

    The nameless container expands nothing on another package's object. It is pinned with a stored row whose body carries no name. Its alternative would be the shadow this card removes. Whether the save door can store such a body is not measured, so this is an Acceptance note.

• The changeset prose, checked by the seat against the diff and the measurements:

  • :9, the old naming (OBJECT.default, OBJECT.form, OBJECT.KEY) and "still stamped with the shipping package's _packageId and _provenance: 'package'": this matches round 0's H1 table (in-process and REST) and the old expandViewContainer(viewObject, container) call.

  • :10 to :11, the by-name read on each kernel before the fix: this matches the H1 table's rows.

  • :12, "a second list default": round 0 measured two list defaults served over REST.

  • :13 to :16: this matches expandUnderOwnName (the bare list at under; everything else from expandViewContainer(under, …)).

  • :17, "None of these views carries isDefault": this matches the delete item.isDefault line. "Every name the shipping package serves answers its packaged view on both reads" matches the 30 member cases and the REST probes.

  • :18: this matches the underIsShipped branch.

  • :19: this matches if (ownName === undefined) return [];.

  • :20: this matches item._packageId = ownPackageId and the same-package artifact guard.

  • :21 to :26, "expand exactly as before, isDefault included" and the by-name override: this matches the unchanged expandViewContainer(viewObject, container) arm and the six controls per kernel.

    The package-less overlay of the package's own container is now stamped with the overlaid artifact's package inside the expander. The list read's final governance pass already grafted that package's envelope onto those shipped names, so what is served is the same.

  • :27 to :31, the renamed views and the advice to callers: this matches the derived spellings. A reference to an old name now resolves to the shipping package's view, which is the point of the fix.

• Measured (dev):

  • Round 0 baseline at ceb4a939b: wider than the card. The object door shadowed on every kernel and container scope. The by-name read shadowed too on an unscoped kernel for package-scoped and environment-wide containers, and keyed members shadowed.
  • After: the object door lists exactly one isDefault list view for showcase_task, the packaged showcase_task.default, in-process on both kernels and over REST.
    • objectui's applyViewItem takes the last served isDefault list view, which is now that one. This is a code reading, not browser-measured.
    • Every derived name is _diagnostics.valid: true, with its own _packageId, no _provenance and no isDefault. The final governance pass needed no edit.

• Pins:

  • 46 new in-process cases: the member-kind enumeration derived from ViewSchema.shape (bare list, named list, listViews, formViews, form), with 5 kinds × 3 container scopes × 2 kernels; 6 card-probe cases; 6 controls; and the de-duplication, shipped-key and nameless cases.
  • The dogfood pin over the real showcase through REST: the override control first, then steps 1 to 7, step 8, and the keyed probe, each asserting both doors and the single list default.

• Reverse verification, one arm at a time (the restore proven each time: blob 237a0530d7ad = HEAD, an empty diff):

  • OQ1 arm removed: in-process 36 red / 26 green, with every member and probe case red and the controls green. Dogfood 3 red / 1 green, with the override control green.
  • OQ2 arm reverted to round 0's naming: in-process 26 red / 36 green, with the keyed kinds, de-dup and shipped-key red and the bare list, probes and controls green. Dogfood 1 red (the keyed probe) / 3 green.

• Verification (dev):

  • At f233f22fd7 (to 8976a86f94 only the changeset differs): the full metadata-protocol suite, 3,034 passed and 19 skipped, with typecheck exiting 0; and the full dogfood suite against fresh dists, 1,400 passed and 9 skipped, with typecheck exiting 0.
  • At 8976a86f94: gates 68 derived, 68 run, all exit 0.
  • ESLint on the 3 touched files: 0 errors and 0 warnings.

• Deviations, accepted:

  • Round 0's first tsc ran outside the verify lock; every later run went through it.
  • Round 0's first dogfood reverse run was void (the control ran last) and was repeated with the control first.
  • Round 1's ablations ran with the test file committed one commit later. The mutated protocol.ts was committed, and its restore is proven against HEAD.
  • Two lock waiters timed out behind another seat's holds and were re-queued.
  • The open question on Fixes versus Part of is settled: Fixes stands (5955628428).

• Serial:

  • services seat 2's DELETE /api/v1/packages/:id answers success when the sys_packages delete fails, so the package is gone from the live registry and comes back after the next restart #21276 declared protocol.ts deletePackage only on [PM seat] domain:engine — 🟢 os-project-manager · session_017ErfyP2Rx7XWHJA27QjyUi #6367 (5954791744). That region is disjoint, and it has no open PR at this read.
  • [security] Stored-metadata-body family: two exits #21120 did not reach. An engine-only door serves an administrator credential material in cleartext, and the data door serves a content hash computed over the withheld credentials #21207 (cli lane) edits other protocol.ts regions.
  • Whichever lands second merges main.

• CI on this head, read by the seat in this act: 42 latest check runs: 37 success, every required context among them, and 0 failures. All 12 workflows on this head are completed. The 5 skips are Build Docs, Console Pin Gate and Packed-tarball smoke (opt-in) (roster entries in check-expected-skips.mjs), plus Auto Label and Check PR Size. Those two each have a success run on this head (16:29Z) and a skip from the seat's body edit (16:59Z), which the roster describes at :89 to :90.

• Out-of-scope findings:

  • the by-name read of a derived name: filed metadata-protocol: a view that a runtime view container expands is listed by GET /meta/view?object= but answers nothing by name on an environment-scoped kernel or for an org-scoped container — the by-name read expands no container #21442, as above;
  • stale registry expansions after a container delete on an unscoped kernel (reach: the @objectstack/verify harness only; the names are now the container's own): Acceptance notes;
  • the inline byName map's same-name collapse across packages (ADR-0048), read and not measured: Acceptance notes;
  • stampRenameWarning's _diagnostics being replaced by the list door's decoration: Acceptance notes;
  • MetadataManager.getViewsByObject (packages/metadata) expanding containers first-wins, neither touched nor measured: Acceptance notes. It is recorded in this seat's hand-over ledger as a position to measure against this card's rule.

Next: pr_ready, then automerge_enable, as two relay acts. Fixes #21334 closes this card at merge.
