fix(metadata-protocol): one collision predicate at the save door — a stored view container never takes a name already served from elsewhere (#21639, #21638)

[objectstack-fleet]

Fixes #21639
Fixes #21638
Clause-②: no (narrowing)

#21638 carries its own claim on this branch (5975022936), as the Closing-Target Claim Guard requires for every card a PR closes. Triage folded it into #21639's claim.

The runtime save door's accept set narrows: one predicate now refuses a stored view container whose save name, or any name its expansion produces, is a name already served from elsewhere. Nothing widens. A package-less container row stored under the name of a view item a package ships now belongs to no package, as triage's fold of #21638 rules. Dispatched by domain:engine seat 1 under claim 5974259402 (file surface corrected by 5974270195), branch claude/issue-21639-view-container-collision. Triage's ruling 5973827435 and its fold 5973838571 are implemented as written.

What changed

All of it is in packages/metadata-protocol/src/protocol.ts, the claimed surface. The producer is the save door itself, so nothing moved to another package.

• One predicate replaces the two one-shape checks. viewContainerNameCollisionRefusal replaces finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's containerOwnExpansionNameRefusal and The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620's containerSiblingExpansionNameRefusal at the same place in saveMetaItem: after savedItemNameRefusal, before normalizeViewMetadata.
  • What the container would serve is its expansion as the readers place it: expandRuntimeViewContainer with the request's package binding, the binding the row is stored under. The body judged is the authored one with the door's own name stamp applied first.
  • Elsewhere (1), another stored container's expansion in the caller's selection, whatever its object. These are the rows readActiveOverlayRows selects through the readers' gate organizationIdForMetaRead, with no package filter. Each is parsed by storedOverlayEntries and expanded by expandStoredViewContainers with its own binding. The row stored under the save name is left out, because it is the row this save replaces. The same object qualifier is gone, as ruling (1) B says, and so is the now-unused deriveViewContainerObject import.
  • Elsewhere (2), a view item a package ships. lookupArtifactItem answers, and the artifact must carry viewKind (isShippedViewItem, a new module-level predicate). One exception: the views of the shipped container this row overlays by its own name (overlaidShippedContainerViewNames). ADR-0005 keys an overlay by its own name, so that container's views are the row's own to replace.
  • The cells, in order: the save name against a sibling's expansion, then against a shipped view item, then against its own expansion (finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's shape); then each expansion name against a sibling's expansion, then against a shipped view item. The first collision answers.
  • The envelope is unchanged: VALIDATION_ERROR / 400, with no new code. Every message names the other owner (the stored container, the shipping package, or "its own expansion") and gives the family's prescription. That is: add the view as a member of the container that owns the name, or save a view item under the name. For a shipped name: save a view item under it, or a name or key of its own. ⛔ No arm prescribes a save under a name another stored row holds. finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's own-expansion arm used to say "Save the container under its object's name" even when a stored container held that name. It now names that container to add the view to.
  • Prescription first, explanation last. A 4xx message crosses the REST boundary bounded at 500 characters with its tail cut (CLIENT_MESSAGE_MAX). The first REST probe of this branch received the shipped-arm prescription cut mid-word, so every message now front-loads the owner and the prescription. The pin asserts both inside the first 500 characters (rest/meta: the /references 501 back-loads its ADR-0110 D3 prescription, so the #5423 bound silently cuts it off for long object names #17584's ordering rule).
• The attribution half (The runtime save door accepts a view container saved under the name of a view item a package ships; package-less, the row is attributed to the shipping package and its bare list replaces that package's default view on both doors #21638), in runtimeViewContainerPackage. A package-less row whose same-named shipped artifact is a view item (viewKind set) now answers no package: "A container row is not an overlay of the item, so it is attributed to no package." A package-less row under a shipped container's name keeps that container's package, as before. A bound row is unchanged.

Census, taken first (the ruling's stop conditions)

(2): does a live writer save a second container of one object on purpose? Readings are at BASE 7b07749f05, re-read after merging origin/main (head d5101d1831). objectui was read at the old pin 89cad75d55 and at the new pin ab1879721595, which origin/main moved to while this ran.

Census input	Evidence	A second container of one object, a container under another container's expanded name, or a container under a shipped view item's name, on purpose?
#13407's authoring path: the platform checklist's live view-authoring item studio-authoring.view-authoring-live (P1, revision 2)	Step 1 saves ONE container, qa_repair_asset_views = { object: 'repair_asset', list, form }, on a runtime-authored object. No other checklist item stores a container on repair_asset. #13407's own repro (a container bound to note under another name, per PR #21637's census) is one container too.	No.
#21412's P2 / P2b (seat answer 5961930912)	One container, lead_views, bound to crm_lead. Pinned in the #21412 block of the same test file, still green.	No.
#21334's arm (rulings 5946423948, 5955628428)	It expands under the container's own name, OBJECT.CONTAINER_NAME and OBJECT.CONTAINER_NAME.KEY, never a name the owning package ships. Pinned as two allowed rows below.	No.
Studio's metadata editor re-save (objectui at both pins)	Creators write view items: the metadata-admin createBuildBody (anchors.ts:291, "Emit a canonical ViewItem"), the spec create seed for view (metadata-create-seeds.ts:62, viewKind: 'list'), and the flat configs of data-objectstack createView and setViewConfig. Re-savers save the loaded body under the name it carries: ResourceEditPage (:1477), the Interfaces pillar's StudioDesignSurface (:2475, new at ab1879721595), and updateView.	No creator writes a container. A re-saver writes a colliding container only when the store already holds the collision, and that re-save is now refused until its body stops colliding.
Package duplication (duplicatePackage, a writer through this door, outside the ruled set)	Throwaway probe, deleted afterwards. A container pone_extra_views in com.example.pone, bound to crm_lead (outside the package, shipped by no code package), duplicated into com.example.ptwo. At BASE: copied, and the object door's crm_lead.default became the copy's, wearing _packageId: com.example.ptwo. The source package's view was silently replaced. At HEAD: failed[] carries this refusal, naming pone_extra_views, and the source's view stays.	Yes, as a byproduct; not on purpose, as this dev reads it. The copy is meant to be an independent base, and the collision is the defect itself. Raised as an open question in the report.
migrateStoredMetadata	It re-saves rows already stored, inside a try that records outcome: 'failed'.	Not a creator.
The in-repo AI author	The MCP tools in packages/mcp/src/mcp-http-tools.ts have no metadata write. skills/objectstack-ui teaches defineView in source.	No. The cloud AI author is outside this repository and the ruled set: NOT MEASURED.
Packaged containers and stored rows	Source registrars never reach this door. The example apps seed no sys_metadata view rows. Hosted tenants: NOT MEASURED.	n/a

The attribution half: does a live overlay path depend on a package-less container row taking a shipped item's package?

• Callers. runtimeViewContainerPackage is called by expandRuntimeViewContainer (and by the new overlaidShippedContainerViewNames). expandRuntimeViewContainer is called by expandStoredViewContainers (the list read, the by-name read's resolveRowlessExpandedView, and this predicate), by hydrateExpandedViewItems (the registry), and by the predicate itself.
• The overlay that does take a package is unchanged and pinned (CONTROL): a package-less row under the package's own container name. That is the path behind the checklist's packaged-display-class-direct-edit designer overlay.
• No writer stores a package-less container under a view item's name. Studio's creators write view items, the save door now refuses the shape, and the restore doors and draft promotion re-write only bodies already stored.
• Verdict: no live overlay path depends on it, so the ruling's attribution lands.

Every accept-set change at saveMetaItem, type view

Each row covers publish and draft mode, both scopes and both kernels. "Stored container" means one in the caller's selection.

Input	Before (BASE 7b07749f05)	After
A container bound to another object, under a name a stored container expands	Accepted: stored, and registered on an unscoped kernel. The sibling's view under that name was served by neither door, and the by-name read answered the raw container.	Refused VALIDATION_ERROR / 400, naming the stored container. Nothing is stored or registered.
An unbound container under such a name	Same as above.	Same as above.
A container whose expansion takes a name a stored container already expands: a second container of one object whose bare list takes OBJECT.default, under a free name or under the object's name	Accepted. The one read last replaced the other's view on both doors.	Refused, naming the stored container.
A container under the name of a view item a package ships: package-less, organization-scoped, or bound to a writable package	Accepted. The packaged view was no longer listed on the object door, and by-name answered the raw container. Package-less, the row also took the shipping package, so its bare list replaced OBJECT.default on both doors with that package's _packageId.	Refused, naming the package.
An overlay of a package's own container whose member takes the name of a view item the package ships on its own	Accepted. The member replaced that packaged view on both doors.	Refused, naming the package.
A container under its own expanded name (#21558), or under a name another stored container of the same object expands (#21620)	Refused VALIDATION_ERROR / 400.	Refused, with the same envelope. The prescription now comes first, and the own-expansion arm no longer prescribes a save under a name a stored container holds.
A form-only container under a registered view item's name	Refused VALIDATION_ERROR / 400 under #21558 or #21620. Under any other registered name: 422 from the identity stamp.	Every shape this predicate covers is refused VALIDATION_ERROR / 400 first, before the stamp.
Everything else	Unchanged.	Unchanged.

Rows already stored. They keep their bytes, and no row is re-saved. A package-less container row stored under a shipped view item's name now reads as belonging to no package:

• On that package's object it expands under its own name (showcase_task.showcase_task.in_progress), with no _packageId and no default.
• The packaged views it used to replace (showcase_task.default, or showcase_task.edit for a listViews.edit member) are served again on both doors (pinned).
• The row still takes its own name's slot on both doors. That is the read doors' name-keyed overlay, out of surface and unchanged.

A new save of a row in a refused shape, a re-save included, is refused until its body stops colliding. Delete stays open.

The enumeration pin (the card's acceptance)

view-container-runtime-expansion.test.ts, block #21639. Each row runs on both kernels (env_local and unscoped) and both scopes, unless the row names one scope.

• A refused row asserts:
  • code and status;
  • the save name, the colliding name and the owner;
  • the owner and the view-item prescription inside the first 500 characters;
  • that no stored row's name is ever prescribed as a name to save under;
  • in publish and in draft mode, that nothing is stored or registered;
  • that the owner's view still answers on both doors.
• An allowed row asserts that it saves, and that each named view answers on both doors.
• The structural tests fail when:
  • a row is neither refused nor allowed, or is both;
  • a ruled shape has no row;
  • a cell of the predicate has no refused row.

#	Shape	Verdict	Owner named / reason
1	A container under a name its own expansion produces (#21558's own-expansion name)	REFUSED	its own expansion
2	The same, while a stored container holds its object's name	REFUSED	its own expansion; the prescription names that container
3	A container of the same object under a name a stored container expands (#21620's sibling)	REFUSED	the stored container crm_lead
4	A container bound to another object under that name ((1)'s other-object container)	REFUSED	the stored container crm_lead
5	An unbound container under that name ((1)'s unbound container)	REFUSED	the stored container crm_lead
6	A second container of one object, free name, bare list on OBJECT.default ((2)'s second container default)	REFUSED	the stored container crm_lead
7	A container under its object's name, after a free-named container took OBJECT.default	REFUSED	the stored container lead_other_views
8	A package-less container under a shipped view item's name (#21638's shipped item name)	REFUSED	the package com.example.showcase
9	A writable-package container under a shipped view item's name	REFUSED	the package com.example.showcase
10	An overlay of the package's container whose new member takes a view item the package ships on its own	REFUSED	the package com.example.showcase
11	A view item under a stored container's expanded name (allowed: #21510's sanctioned override)	ALLOWED	a view item is not a container: it is that name's sanctioned override
12	A view item under a shipped view item's name	ALLOWED	the sanctioned override of the packaged view by name
13	A container under its object's name (allowed)	ALLOWED	the container contract's own name (ADR-0017 §3.2), and nothing it expands is served elsewhere
14	A container's own re-save	ALLOWED	the row under the save name is the row this save replaces
15	A container under a name of its own beside a sibling, with names the sibling does not expand	ALLOWED	the census writers' shape, colliding with nothing
16	An overlay of the package's own container, by its own name	ALLOWED	ADR-0005: the row stands in for the shipped container and its views
17	A package-less container on another package's object	ALLOWED	#21334's arm: its names derive from its own name
18	The same, in a writable package	ALLOWED	#21334's arm, bound to its own package
19	Under another organization's container's expanded name (organization scope)	ALLOWED	the caller's selection decides, as it does for the readers
20	An environment-wide container under an organization's container's expanded name (environment scope)	ALLOWED	the caller's selection decides; reading every organization's rows at an environment-wide save would be a cross-tenant read

The PM's mechanism hypotheses

• H1, confirmed at 7b07749f05. saveMetaItem called containerOwnExpansionNameRefusal and then containerSiblingExpansionNameRefusal, both before normalizeViewMetadata and both VALIDATION_ERROR / 400. Both are replaced by the one predicate.
  • Every finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558 and The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620 pin keeps its envelope and its intent: the file is green, and leg 1 below turns all of them red.
  • finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's showcase pins now also assert the owner the predicate names. Every name they save under is one the showcase ships, so the shipped-item arm answers there. The The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620 block gains a one-paragraph note.
• H2, measured.
  • The allowed shapes collide as follows. A container's own re-save collides with nothing once its row is left out. An overlay of its own package's container collides with every packaged name it re-expands; the overlaid container's views are excluded, as the ruling's ADR-0005 reading requires. 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 #21334's own-name arm collides with nothing.
  • The line drawn: a container under its object's name is allowed when it expands no name served elsewhere. Saved after a free-named sibling of that object took OBJECT.default, it is (2)'s shape and refused (row 7).
• H3, confirmed. "A view item a package ships" is lookupArtifactItem, the registry's artifact read, which never answers a tenant-authored row, holding an artifact with viewKind set.
  • The first spelling ("not a container") refused sys-metadata-repository.package-writability.test.ts's ADR-0005 overlay preservation pin. That fixture's artifact stub is neither a container nor a view item. The predicate is now positive, and that pin is green.
  • finding(metadata-protocol): a stored view row named exactly like a container expansion is shadowed in the object door by the expansion, while the by-name read answers the stored row #21510's sanctioned override stays allowed (rows 11 and 12).
• H4, confirmed. The callers and the live overlay path are listed above. Rows stored before this change get the reading named above.
• H5, kept by construction. The predicate is not gated on source or writeFace, so migrateStoredMetadata and duplicatePackage record the refusal as the row's failure. Duplication was measured (the census row above).

Tests

All readings are at HEAD d5101d1831 unless named otherwise.

• Premise.
  • Method: the new pins, run against BASE's protocol.ts (blob 56bc12dce760), restored by a trap-guarded script. Restore proof: blob e5765e5ba0f9 equal to HEAD at 0af0f28e49, and git diff HEAD empty. The command: vitest run src/view-container-runtime-expansion.test.ts -t '#21639|#21638'.
  • Result: 40 failed, 50 passed (231 skipped).
  • Red:
    • the 7 newly refused shapes × 2 scopes × 2 kernels (28), each failing on the save is refused;
    • row 2 × 4, where BASE's arm reads "Save the container under its object's name, 'crm_lead'" while a stored container holds crm_lead;
    • the 8 attribution pins, where the packaged label and config were replaced.
  • Green: rows 1 and 3, every allowed row, the 2 structural tests, and the 4 attribution controls.
• New pins: 90.
  • The enumeration block: 2 structural tests + 76 row cells.
  • The #21638 attribution block: 2 at-rest cases + 1 control, × 2 scopes × 2 kernels.
• The file: 321 passed (231 pre-existing + 90).
• The package: pnpm --filter @objectstack/metadata-protocol exec vitest run --maxWorkers=2 gives Test Files 209 passed, 3 skipped (212); Tests 3463 passed, 19 skipped (3482); VERDICT command-exit 0.
• Typecheck: pnpm --filter @objectstack/metadata-protocol typecheck (tsc --noEmit) exits 0, and tsc --noEmit --listFiles includes the test file.
• Downstream sample.
  • Direction: consumers (downstream) of @objectstack/metadata-protocol.
  • Build: against dist/ rebuilt at d5101d1831 by turbo run build --filter='@objectstack/dogfood^...' --filter='@objectstack/metadata-protocol...' --concurrency=2: 63 of 63 tasks. The built dist/index.js carries the new predicate, and the old method names are gone from it.

  • rest, 1 file, 7 tests: public-form-routes.stored-row.
  • dogfood, 2 files, 7 tests: view-container-cross-package-default (PR fix(metadata-protocol): a bare-list view container on another package's object expands under its own name #21430's pin over REST) and view-container-default-form.
  • All pass. The rest of the downstream run is CI's.
• Over REST, measured with a throwaway dogfood probe on the booted showcase, deleted afterwards:
  • PUT /api/v1/meta/view/showcase_task.in_progress with a container answers 400 VALIDATION_ERROR, and the object door still serves showcase_task.in_progress as "In Progress" from com.example.showcase;
  • a second container on one runtime object answers 400;
  • a view item under the shipped name answers 200.

Reverse verification

The change was committed first. Both legs ran from committed e5ac5cf14a, the same protocol.ts blob as HEAD, since the later merge touched nothing under metadata-protocol. Each leg was a trap-guarded script around scripts/ablation-replace.mjs --delete.

• Leg 1, the predicate's throw, anchor if (containerCollision) throw containerCollision;.
  • Mutation: the anchor went from 1 occurrence to 0, and the blob from f853b383e1b2 to be22198e5e1f. Predicted direction: red.
  • Result: 104 failed, 217 passed. That is every refusal pin in the file: the Two stored view containers of one object still displace each other's views: a container bound elsewhere or unbound under a sibling's expanded name, and a second container's bare list taking the first's <object>.default, are accepted with no diagnostic #21639 refused rows (40), finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's showcase block (24), The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620's block (36) and finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's runtime-object block (4).
  • Green: every allowed row, every control and the attribution block.
  • Restore: blob f853b383e1b2, equal to HEAD, and git diff HEAD empty. Both the tool and the script's trap proved it.
• Leg 2, the attribution guard, anchor if (isShippedViewItem(overlaid)) return undefined;.
  • Mutation: the anchor went from 1 occurrence to 0, and the blob from f853b383e1b2 to 55cc79455d20. Predicted direction: only the at-rest pins turn red.
  • Result: 8 failed, 313 passed. Exactly the 8 at-rest attribution pins turned red. The 4 controls and every save-door pin stayed green.
  • Restore proven the same way.
• No dist leg. The subject is imported through ./index.js, the source.

Gates

node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack, with no paths, at d5101d1831 derives 64 families. That is the dispatch lead's 56 plus the 8 the changeset adds:

  • Repo-wide pnpm lint is CI's.

• Branch state: origin/main was merged twice, f30588ceb7 and then d5101d1831. Neither moved a byte under packages/metadata-protocol.

Acceptance notes

• Rows of one name in two bindings. "The row under the save name" excludes every row of that name in the selection, as The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620's check did. Two containers sharing one name in two bindings are therefore not judged against each other: a package-less row and a writable package's row, or a duplicate whose name carries no namespace prefix. Read, not measured.
• An environment-wide save, an organization's sibling (row 20). The save is allowed by the ruling's "in the caller's selection", and for that organization the sibling's view is gone. Noted, not filed.
• Restore and publish doors. rollbackMetaItem, revertCommit and the draft promotion do not run the predicate, as for finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558 and The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620. A draft saved before its sibling existed can be promoted into a collision.
• A disabled package's shipped view item still counts as served, because the registry's artifact read does not ask whether the package is enabled.
• A stored row's own name is not "elsewhere" in the ruling. A container stored at a name before a sibling gains a member of that name keeps the name, as PR fix(metadata-protocol): the save door refuses a view container saved under a name another stored container of the same object expands to (#21620) #21637 noted.
• The at-rest The runtime save door accepts a view container saved under the name of a view item a package ships; package-less, the row is attributed to the shipping package and its bare list replaces that package's default view on both doors #21638 row still takes its own name's slot on both doors. That is the read doors' name-keyed overlay, out of the claimed surface.
• Cost. A container save reads the caller's active view rows once, through the readers' row cache, as The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620's check did. It also asks the registry's artifact read once per name it would serve. A view item pays nothing.
• Declaration bytes. dist/index.d.ts swaps two private member lines for two: viewContainerNameCollisionRefusal and overlaidShippedContainerViewNames. No public member or exported type changes.
• The changeset is .changeset/21639-view-container-name-collision.md: '@objectstack/metadata-protocol': minor, Clause-②: no (narrowing), the BREAKING banner, the ADR-0087 disposition not-required (no-migration-prescription) written from this census, and a before/after per shape.

What this run could not see

• the SDK route bridge reached 54 of 206 client-bound route-ledger rows — the other 152 have no registrar path: tail to select them, so pages documenting THEIR client methods cannot appear above, on this or any run. Of those 152: 0 are remediable by widening that discovery convention (an in-repo file declares the path; the convention did not scan it); 55 are structural — on a ledger where NOT ONE row is declared in-repo, so no discovery change reaches them at any price; 97 are undecided (no in-repo declaration, on a ledger that has other in-repo registrars — absence and an unreadable spelling are not distinguishable here). The rows themselves: node scripts/docs-audit/affected-docs.mjs --bridge-coverage
• a page that states a rule by its inputs shares no identifier with the emitter that implements the rule, so an emitter-only diff cannot list it — not on this run and not on any run. Measured on fix(driver-sql): emit varchar(maxLength) for a text field a declared index keys on #11430: content/docs/protocol/objectql/types.mdx documents the text-family column mapping by the ObjectQL type names it maps FROM (text / textarea / html) while the diff changed createColumn; it went unlisted, and it was the page that diff falsified, in four places. No shared token exists to detect this on, so a rule your change carries has to be re-read by hand in the pages that restate it.
• a key NAME is not a key, so the hand re-read the line above prescribes can land on the wrong schema. The same spelling is authorable on one governed type and a [REMOVED] tombstone on another for each of active, aria, joins, objects, template, tools and version (censused on [finding] tools is a key on BOTH AgentSchema (tombstoned, dead) and SkillSchema (live, cloud-attested), so a name-based search attributes skill examples to the agent key — it produced a false stop-the-line alarm on PR #19059 #19093 over the liveness ledger's governed types, top-level keys); nothing in a search result distinguishes the two, so a grep hit on a LIVE example reads as evidence about the DEAD key. Measured on fix(spec): the agent.tools liveness row says dead — it claimed live on a key the schema tombstoned #19059: content/docs/ai/agents.mdx was reported as contradicting the agent.tools tombstone over its tools: example at :161, which is inside the defineSkill({ block opened at :155 — the page was already correct. Settle ownership by PARSING the value against both schemas, never by the name: that literal PASSES SkillSchema, and as an AgentSchema it FAILS at tools with the tombstone prescription. ⛔ These names are not the whole class — a key retired through a .strict() guidance map leaves no tombstone in the walked shape and none of them here (tool.category, live as AIToolDefinition.category).

Coarse fallback — 11 page(s) merely mention a changed package (the pre-#9192 predicate, kept for the deliberately-wide backstop): node scripts/docs-audit/affected-docs.mjs --json 15fe567c9c74e088684944094aa686b9bd3b386c → packageMentionDocs.

Which tree this was computed on

This run read content/docs from 12468018e89ae330cf1119538c72b97b1908066b — the merge of head d5101d18311ef0fd7dc5daa08c1264ce06ca545c into base 15fe567c9c74e088684944094aa686b9bd3b386c, which is what actions/checkout gives a pull_request run. Not the PR head.

A worktree cut from an older main holds a different content/docs, so re-deriving there can legitimately return a different list — that is a different tree, not a wrong row. To answer on the same tree:

# while this PR is open — GitHub drops the merge commit once it closes
git fetch origin 12468018e89ae330cf1119538c72b97b1908066b && git checkout 12468018e89ae330cf1119538c72b97b1908066b
# afterwards, rebuild it from the two parents, which stay fetchable
git fetch origin 15fe567c9c74e088684944094aa686b9bd3b386c d5101d18311ef0fd7dc5daa08c1264ce06ca545c && git checkout -B drift-repro 15fe567c9c74e088684944094aa686b9bd3b386c && git merge --no-ff d5101d18311ef0fd7dc5daa08c1264ce06ca545c

⚠️ That checkout carried uncommitted changes, so the commit above does not fully identify what was read.

Advisory only, and a precision-first one (#9192): a page is listed because it names a
symbol, wire route or SDK method this diff touched — not because it mentions a changed
package. Each row says which anchor put it there, so a wrong row is reportable rather than
merely annoying. To re-verify, run the docs-accuracy-audit workflow scoped to these files:
node scripts/docs-audit/affected-docs.mjs 15fe567c9c74e088684944094aa686b9bd3b386c → pass the list as
args.docs, on the commit named under Which tree this was computed on.

ACCEPT — PR #21648 at head d5101d1831 (#21639, with #21638 folded in)

domain:engine#1 · session_017ErfyP2Rx7XWHJA27QjyUi · read at 2026-10-04T00:05Z. The os-dev report is on #21639. Judged against GitHub and the branch, not against the report.

• Shape: draft, base main, assignee os-project-manager.
  • The first lines are Fixes #21639, Fixes #21638 and Clause-②: no (narrowing), copied from the claim.
  • Both closing keywords are intended: triage folded The runtime save door accepts a view container saved under the name of a view item a package ships; package-less, the row is attributed to the shipping package and its bare list replaces that package's default view on both doors #21638 into this claim (5973838571). The scan finds no other card.
• Scope: 3 files, +746/-183: protocol.ts, the pin file and the changeset. check-governed-merges reports NOT governed.
• The diff, read (non-comment lines):
  • One predicate, viewContainerNameCollisionRefusal, replaces finding(metadata-protocol): the runtime save door accepts a view container saved under one of its own expanded names, and after #21510's rule no door answers a view item for that name #21558's and The runtime save door accepts a view container saved under a name ANOTHER container expands to; the object door then lists the second container's list in place of the first's default, and no door answers a view item under the saved name #21620's two checks at the same place in saveMetaItem.
  • It judges the save name first: a stored sibling's expansion, then a shipped view item, then the container's own expansion. Then it judges every name the body's own expansion produces against the stored siblings and the shipped items.
  • Siblings are the caller's own selection, with every row under the save name excluded, and the object qualifier is gone. That is ruling (1) B.
  • "Shipped" is positive: lookupArtifactItem answers an artifact with viewKind and a package. It excludes the views of the shipped container this row overlays by its own name (ADR-0005), so an overlay stays allowed.
  • The runtime save door accepts a view container saved under the name of a view item a package ships; package-less, the row is attributed to the shipping package and its bare list replaces that package's default view on both doors #21638's attribution half: runtimeViewContainerPackage gives no package to a package-less container row whose same-named shipped artifact is a view item. An overlay of a shipped container keeps its package. That is the ruling's "a container row is not an overlay of the item".
• Prescriptions, checked against the family rule. Each message names the other owner, and none prescribes a save under a name another stored row holds.
  • The own-expansion arm keeps "save under its object's name" only when no stored row holds that name. Otherwise it names that container, or a name of its own.
  • Deviation 1 (prescription first) — accepted. Ordering the prescription before the explanation is a measured fix: the first REST probe received the shipped-arm prescription cut at the 500-character bound (CLIENT_MESSAGE_MAX). A pin holds the owner and the view-item arm inside the first 500 characters.
• The enumeration pin is the card's acceptance: 20 rows, each either refused (with its owner) or allowed (with its reason).
  • Structural tests fail on a row that is neither or both, on a ruled shape with no row, and on a predicate cell with no refused row.
  • Row 7 is accepted on the ruling's literal rule: the object-named container is refused after a free-named container took OBJECT.default. Only a row stored before this change can produce it, because row 6 now refuses the free-named one. The message names that container.
• Open question (package duplication) — the seat answers A. Package duplication can copy a container whose object is outside the copied package into a second container of that object. That is a byproduct, not a writer saving one on purpose, so (2)'s stop condition does not fire.
  • Before this change, the copy silently took the source's view, which ADR-0126 rules out.
  • It now lands in failed[] with the refusal and its remedy.
  • B would re-open the precedence order the ruling forbids. C is a new duplication behaviour and a new card if anyone asks for it.
  • The changeset states it.
• Clause-②: no (narrowing) — accepted. There is no path leg and nothing widens. The attribution change restores packaged views a row used to hide, which is not a new accepted input. No contract review is owed.
• Changeset, checked against the diff:
  • minor, the BREAKING banner, and adr-0087: not-required (no-migration-prescription) with the census facts, including duplication.
  • "One rule" matches the predicate's order and arms.
  • Each "before and after per shape" bullet matches an enumeration row: 4 and 5, 6 and 7, 8 and 9, 10, and 1 to 3.
  • "What still saves" matches rows 11 to 20.
  • "Rows stored before this change" matches the attribution branch: a row named after a shipped item expands under its own name with no package, and the packaged views come back.
  • "The fix" carries the family's arms.
• Evidence:

  • Premise at BASE: 40 of the 90 new pins red, in exactly the newly refused cells, row 2's old prescription and the 8 at-rest attribution pins.

  • Suites: the package passes 3463 of 3463, typecheck exits 0, and the downstream objectql, rest and dogfood samples are green.

  • REST probes on the booted showcase: a 400 for a container under a shipped name and for a second container, and a 200 for a view item under the shipped name.

  • Reverse verification, two legs:

    • the predicate's throw ablated: 104 refusal pins red across all four families, and every allowed row and control green;
    • the attribution guard ablated: exactly the 8 at-rest pins red.

    Both restores were proved by blob equality.

  • Gates: dispatch-gates --ran reconciles 64 of 64.

• CI on d5101d18, at this read: 12 check runs are in progress, and check-expected-skips is NOT MEASURED. The seat lands only once every check is green or an expected skip.

Out-of-scope, noted, not filed:

• two same-name rows in two bindings are not judged against each other;
• the restore and publish doors, the family note PRs fix(metadata-protocol): the save door refuses a view container saved under a name its own expansion produces (#21558) #21618 and fix(metadata-protocol): the save door refuses a view container saved under a name another stored container of the same object expands to (#21620) #21637 also carried;
• a disabled package's shipped item still counts as served (read, not measured).
