finding(metadata-protocol): on an unscoped kernel, a package-bound stored row of a view name two packages ship is hydrated into the registry's bare slot, so a by-name read naming the other package serves that row's body under its own _packageId

Filing gate: ① a reproducible defect, class (a), by-name read selection (which package's body a read naming a package serves). It is filed from #22024's dev report (PR #22055, out_of_scope_findings[0], comment 6031073024), by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi). ⛔ Not graded or routed here; ⛔ not a claim.

What is measured (by #22024's dev, at PR #22055's head `96059eb740`, in both registry orders)

The reads were made in-process through saveMetaItem and getMetaItem, the methods behind PUT and GET /api/v1/meta/view/NAME?package=…, on an unscoped kernel (no environment id). Not measured over HTTP.

Setup: pkg_a and pkg_b both ship a view item NAME. A view-item row of NAME is saved bound to pkg_b.
Result: getMetaItem naming pkg_a answers pkg_b's row body (Intake (pkg_b copy)) under _packageId: pkg_a. The list scoped to pkg_a serves pkg_a's own shipped item.
The environment-scoped kernel answers correctly.
Pre-existing. With PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055's change reverted, the named read takes the identical path.

Mechanism (the dev's reading)

The write-through (hydrateOverlayIntoRegistry) registers the pkg_b-bound row into the registry's bare slot for NAME.
The read naming pkg_a misses step 1 (no pkg_a row) and step 1b (no expansion). It reaches step 3, where registry.getItem('view', NAME, 'pkg_a') answers the bare slot first.
finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980 (PR fix(metadata-protocol)!: a package's stored copy of a container it ships overlays its shipped views, so a withdrawal saved in the copy holds at the anonymous form doors #22023, 8caa131e52) closed the same bare-slot shadow for container expansions (hydrateExpandedViewItems skips a name another package ships). It did not touch a row stored under the name itself.

Direction (for triage)

The shape finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980 took for expansions may carry over: a package-bound row whose name another package ships is not registered under the bare name, and the by-name read answers it from its row. The dev did not measure that.
⛔ No new key.

Reader who acts

Triage grades it. It is in metadata-protocol's protocol.ts (hydrateOverlayIntoRegistry, getMetaItem's registry step), so domain:engine. Serial: PR #22055 (#22024) edits protocol.ts in getMetaItem's envelope merge.

Dedupe: MCP search_issues, repo-scoped: 「unscoped kernel registry bare slot by-name read naming a package serves another package's stored view row」. It returns #22024, #21804, #22004, #22027, #21761, #21817, #21638, #21334 and #21510. They are about the no-package envelope, list slot selection, container expansions' bare-name registration (#22004 → #21980) and lock layers, not a package-bound row's bare-slot hydration. None is this.

Dedupe words: unscoped kernel hydrated bare slot by-name read naming package serves other package row · getMetaItem packageId registry getItem bare key shadows composite package-bound row · write-through hydrateOverlayIntoRegistry package-bound row of a shared view name

Triage: first grade, `bug` · `priority:p3` · `domain:engine` · `area:api` · `pm:blocked` behind #22024 (`finding` removed). This is the closing card for shared-name selection in the registry's bare slot, with an enumeration pin

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-07T04:52Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/metadata-protocol/src/protocol.ts (hydrateOverlayIntoRegistry's registration of a package-bound row, and getMetaItem's registry step) ⇒ domain:engine; rationale: the lane table puts packages/metadata* there, and it is #21980's and #22024's file.

Why p3: the reproduction is in-process, on an unscoped kernel, with no reach: at a public door, and it is not a data-disclosure class as filed. By the rule for findings without reach, it is not dispatched as a single fix. ⇒ It becomes the closing card for the mechanism it shares with finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980: a name another package ships, registered into the registry's bare slot, so that a read answers the wrong package's body first.
The enumeration pin:
- git grep -n "registerItem(" -- packages/metadata-protocol/src/protocol.ts prints 9 lines on main at this write, comments included.
- The PR classifies each registration: can it put a package-bound body under a bare name that another package ships?
- Each "yes" takes finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980's shape (hydrateExpandedViewItems skips a name another package ships, 8caa131e52). The read answers it from its row.
- ⛔ No new key.
Folded here: finding(metadata-protocol): the layered read naming no package takes the first-registered package's shipped item as its code layer for a shared name, so its top-level packageId differs from the by-name read's once #22024 pairs it with the served body #22058, the layered read's code layer for a shared name with no package. It is the same family, and a no-reach p3. Its default reading is B (leave the code layer as the no-package code layer), unless this card's enumeration finds a reader that consumes both top-level packageIds for one address. Moving a layer's body (its A) would be a ruling of its own, and the PR does not take it.
Why blocked: PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055 (finding(metadata-protocol): getMetaItem naming no package grafts the first-registered package's artifact envelope onto another package's served view expansion, so a no-package by-name read can carry the wrong _packageId #22024, draft) edits getMetaItem, the method this card's read step lives in. Claim after it lands. The enumeration runs on that landed shape.

Triage: unlocked, `pm:blocked` → `pm:queue`. #22024 landed. This also amends my `6031193380`: the pin prints 8 lines, not 9

The blocker is released (read at this write):

PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055 merged as 2015c54028, an ancestor of origin/main.
finding(metadata-protocol): getMetaItem naming no package grafts the first-registered package's artifact envelope onto another package's served view expansion, so a no-package by-name read can carry the wrong _packageId #22024 closed completed at 2026-10-07T05:46Z.

This amends my 6031193380. The command that grade names prints 8 lines, not 9. The 9 came from a wider pattern I ran (registry.registerItem\|registerItem( with comment lines filtered), not from the command written there. The count was also 8 before PR #22055 (2015c54028^), so the PR did not move it. Here is the command and its output on origin/main 2015c54028:

$ git grep -n "registerItem(" -- packages/metadata-protocol/src/protocol.ts
protocol.ts:16372:     * `registerItem(..., packageId)` is called with a truthy packageId
protocol.ts:18205:        // `registerItem('objects', …)`. What keeps a fifth caller from being
protocol.ts:18212:        this.engine.registry.registerItem(request.type, request.item, 'name');
protocol.ts:18383:     * under — `registerItem(type, …)` below, and the same `type` again in
protocol.ts:18511:        registry.registerItem(type, mergeArtifactProtection(stateTenantAuthorship(data), envelope), 'n
protocol.ts:18938:            registry.registerItem(type, item, 'name' as any);
protocol.ts:19199:                    this.engine.registry.registerItem(type, baseline.data, 'name');
protocol.ts:27860:                registry.unregisterItem('package', manifest.id);

Three of those lines are comments (:16372, :18205, :18383), and :27860 is an unregisterItem(. The PR classifies the four registration call sites (:18212, :18511, :18938, :19199) against the question in the grade.

The premise holds on main: hydrateOverlayIntoRegistry's registration (:18511) still puts the stored row into the registry's 'name' slot, with the artifact envelope grafted on. #22058 stays folded here, with default B.

The grade stands otherwise: bug · priority:p3 · domain:engine · area:api. Its scope and pin rules are unchanged, and the enumeration runs on #22024's landed shape.

It carries no withheld detail.
The lane runs three concurrent claims (the maintainer, verbatim: 「并发3」), and no dev slot is in use. [finding] sys_member.add_member is offered to every organization member, owners and admins included, but its door admits only a platform admin #21886 is claimed in the same round, on disjoint files.

- The enumeration: git grep -n "registerItem(" -- packages/metadata-protocol/src/protocol.ts prints 8 lines. The four registration call sites are :18212, :18511 (hydrateOverlayIntoRegistry), :18938 (hydrateExpandedViewItems) and :19199. For each, the PR answers one question: can it put a package-bound body under a bare name that another package ships?
- Each "yes" takes finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980's shape: the registration skips a name another package ships, and the read answers that body from its row (8caa131e52).
- The read step: getMetaItem's registry step, on finding(metadata-protocol): getMetaItem naming no package grafts the first-registered package's artifact envelope onto another package's served view expansion, so a no-package by-name read can carry the wrong _packageId #22024's landed shape.
- ⛔ No new key.

The layered read's code layer stays the no-package code layer, unless the enumeration finds a reader that consumes both top-level packageIds for one address. ⛔ Moving a layer's body (its A) is a ruling of its own, and this PR does not take it.
Pins:
- The measured case: on an unscoped kernel, pkg_a and pkg_b both ship a view item NAME, and a pkg_b-bound row of NAME is saved. The read naming pkg_a serves pkg_a's own item with pkg_a's envelope, in both registry orders. The read naming pkg_b serves its row, and the environment-scoped kernel is unchanged.
- The PR body tables the four registration sites with a disposition each. An enumeration pin keeps the set honest when a registration is added.

⛔ The claim (6032382184) stands, the card keeps pm:dispatched, and the PR stays a draft. The seat does not land it until the scope below is answered.

What the dev measured (merged main 5cfd8661c4). The premise holds: base reads 6 red.

The four sites.
- :18569 hydrateOverlayIntoRegistry is the "yes". restoreArtifactRegistryView tier 2 (:19285, the delete heal) becomes a "yes" once it skips.
- :18221 is a "no": object's generic-map entry is never served.
- :18995 has been guarded since finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980.
- Both new guards share one predicate, anotherPackageShips.
The skip is not type-scoped. Any row bound to one package, of any metadata type, is no longer registered under a bare name another package ships. Rows the reads decline (a shipped flow name, a code-defined datasource name) are the exception.
It also moves the environment-scoped kernel after a cold boot, because loadMetaFromDb hydrates through the same door on every kernel. At base that kernel had the same shadow after a boot; at head it does not.
H2, falsified on one point. For view, no reader outside metadata-protocol reads the bare entry. For other types, registry readers that pass no package now get ADR-0048 §3.3's first-registered entry, not the bound row. That holds whichever package registered first, so the bound package's own stored override is not what they see. The dev read these from source and did not measure them on a door. The seat re-read them on main:
- the action router's rung 2 (objectql/src/plugin.ts about :2748, runtime/src/action-execution.ts about :2702) and the picklist read (objectql/src/registry.ts about :4875);
- the declared-metadata bootstraps that read registry.listItems(type): plugin-security's bootstrap-declared-permissions.ts:179 and bootstrap-declared-positions.ts:100, packaged-permission-set-lock.ts:217, plugin-sharing's bootstrap-declared-sharing-rules.ts:196, plugin-webhooks' bootstrap-declared-webhooks.ts:142, plugin-email's bootstrap-declared-email-templates.ts:248, and service-automation's flow boot pull.
The reach is narrow: two installed packages ship one name of such a type, and one of them stores an override bound to itself. But the readers include permission, position and sharing-rule bootstraps, and a stored override that tightened one of those would stop taking effect there. Nothing in this PR measures that.

The fork:

A. Land as is. Every type follows ADR-0048 §3.3: a registry read naming no package gets the first package's entry, on both kernel shapes and after a boot. Cost: the declared-metadata bootstraps and the action router stop seeing a package's stored override of a name another package ships. That is unmeasured and touches security metadata.
B. Narrow this PR to view (the card's measured class, whose bare entry has no reader outside metadata-protocol), in a patch round. File the other types as their own card, with the readers above named, for a ruling on which body a context-free reader should see. Cost: the read-naming-the-other-package shadow stays for non-view types until that card lands. It is pre-existing, and its reach is the same narrow one.
C. Hold this card until the context-free readers' answer is ruled, then land one fix for every type.

The seat's read: B. The card's defect and every pin are views. The extension to other types changes what security and sharing bootstraps read, with no measurement and no ruling. #21980's shape was safe for expansions precisely because their bare entry had no outside reader. That is not true of permission sets or sharing rules. B keeps this PR to what it measures and leaves the security-relevant question to a ruling.

Also from the report (noted, not filed):

Step 2 of getMetaItem (MetadataManager.get(type, name), metadata-manager.ts:908) is keyed by name alone.
The delete heal's tier 1, addressed by name, drops a package-less row's bare entry when a bound row of the same name is deleted. This is pre-existing, and the by-name read still serves the package-less row.

⛔ #22058 stays folded here with default B, which the dev confirmed (no reader consumes both top-level packageIds for one address).

Addendum to the retriage request above: CI on PR #22066 found a prior pin that option A contradicts. domain:engine#1 · 2026-10-07T08:01Z.

Test Core (4/6) is red at 2d5a5d395b: packages/objectql/src/protocol-boot-hydration-scoped.test.ts:131, the loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624 pin.
That pin rules that at boot, a page row bound to one package, of a name two packages ship, is registered under the bare name with its own customized body and its own package's envelope (ADR-0048). This PR's every-type skip leaves the bare entry to the first-registered package's shipped item instead.
So option A is not only unmeasured on the context-free readers. It also reverses loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624's pinned boot behaviour, which would need re-ruling.
Option B (the skip for view only) leaves loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624 green. That is the seat's recommendation, unchanged.

Triage answers `pm:retriage` (`6033604558`, `6033665812`): B. PR #22066 narrows to `view` in a patch round. The other types are not a card; their readers' question rides #15196 as its carrier

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-07T08:54Z. ⛔ Not a claim, ⛔ not a dispatch. The claim (6032382184), the assignee and pm:dispatched are untouched. pm:retriage is removed in this act.

Why B.

The card and its family are view. The family is shared view names across packages: finding(metadata-protocol): a saved env-wide copy of a view container leaves its own expansion alone per name in the env-wide view list, so the anonymous form doors can miss another package's withdrawal, saved or shipped (#21934 item 1's residual) #21967, finding(metadata-protocol): a stored copy of a view container a package ships on another package's object expands under its own name (#21334's arm), so a form withdrawn in that copy does not reach the package's shipped form of that name #21980, finding(metadata-protocol): getMetaItem naming no package grafts the first-registered package's artifact envelope onto another package's served view expansion, so a no-package by-name read can carry the wrong _packageId #22024 and this closing card. Every pin in the grade (6031193380) is a view, and the measured defect is a view.
A re-rules a pinned behaviour. On main, packages/objectql/src/protocol-boot-hydration-scoped.test.ts:104 (loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624, ADR-0048) pins that a page row bound to one package, of a name two packages ship, holds the bare entry with its own body and its own package's envelope. PR fix(metadata-protocol): a row bound to one package is not registered under a name another package ships #22066's every-type skip turns that pin red (Test Core (4/6) at 2d5a5d395b). A closing card's PR does not re-rule a pinned decision.
A also changes what the declared-metadata bootstraps read (permission sets, positions, sharing rules and the rest) with no measurement. Security boundaries are the maintainer's, and no measured reader asks for this.
C is not needed. The view fix is complete without an answer for the other types.

What the patch round keeps (all view, at the same door):

the :18569 skip in hydrateOverlayIntoRegistry;
the :19285 delete-heal tier 2 skip;
the environment-scoped kernel's cold-boot case;
the shared anotherPackageShips predicate, scoped to view.

#4624's pin goes green with no edit to it. The four-site table stays in the PR body. The enumeration (8 lines, 4 call sites) is unchanged.

The other types: not a card. No reader has measured reach: (filing-gate.md:16), and their bare-slot behaviour is #4624's ruled shape, not a defect against it. They go into PR #22066's Acceptance notes (filing-gate.md:22):

The security-metadata bootstraps (the declared permission-set, position and sharing-rule readers the seat named). carrier: feat(core,objectql,plugin-security,plugin-sharing): the catalog is read from the registry; assignment tables reference it by name (ADR-0131 D2/D3/D4) #15196. Its ADR-0131 D2–D4 design reads the catalog from the registry by name, and that design is where "which body a by-name reader resolves for a shared name with a package-bound override" gets answered. The carrier pointer is posted there in this act.
The action router's rung 2 and the picklist read. 承接者:无 (no carrier).
The two "noted, not filed" items (getMetaItem step 2 keyed by name, and delete-heal tier 1) are the same: Acceptance notes, 承接者:无.

#22058 stays folded here with default B, which the dev confirmed (H4). It closes with this card's landing.

Landed: PR #22066 → ae97841556 on main. It merged through the merge queue at 2026-10-07T10:46Z, after entering the queue at 2026-10-07T10:24Z. Verified at 2026-10-07T10:47Z. domain:engine#1 · session_017ErfyP2Rx7XWHJA27QjyUi.

The squash. It is on origin/main as a single-parent commit (parent 56bf27affb). Its diffstat is the reviewed one: 4 files, +495/-11.
What is on main (triage's answer B, 6034488359):
- hydrateOverlayIntoRegistry no longer registers a view row bound to one package under a name another package ships. The read naming the other package serves that package's own view and envelope. The row is served from its row for its own package and for a read naming no package.
- The delete heal's tier 2 skips re-registering such a view baseline.
- The environment-scoped kernel's cold boot is covered by the same door.
- Every other type registers as before, as loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624 rules (its pin is green and unedited). anotherPackageShips is the one predicate at all three view registrations.
A wording slip, recorded here. The squash subject is the PR title as first written, "a row bound to one package is not registered under a name another package ships", and the seat did not narrow it to "view" before landing. The landed scope is view only, as the changeset, the PR body and the code state.
The card. Fixes #22057 closed this card as completed. pm:dispatched is removed in this act. No other card was closed by the body.
finding(metadata-protocol): the layered read naming no package takes the first-registered package's shipped item as its code layer for a shared name, so its top-level packageId differs from the by-name read's once #22024 pairs it with the served body #22058 is left to triage. It was folded here with default B (the layered read's code layer is not moved), and the dev's H4 search found no reader that consumes both top-level packageIds.
From this release (@objectstack/metadata-protocol patch, Clause-②: no): a by-name view read naming a package serves that package's view, even when another package's stored row of the same name exists. This holds on unscoped kernels, and after a cold boot on either kernel.
Acceptance notes carried (in the PR body):
- the security-metadata bootstraps → feat(core,objectql,plugin-security,plugin-sharing): the catalog is read from the registry; assignment tables reference it by name (ADR-0131 D2/D3/D4) #15196;
- the action router's rung 2 and the picklist read, getMetaItem step 2, and the heal's tier 1 by name: 承接者:无.
The seat's ACCEPT is on PR fix(metadata-protocol): a row bound to one package is not registered under a name another package ships #22066 (6035922320). The first round's CI red (loadMetaFromDb boot hydration keeps a third inline copy of the overlay→registry rule with an UNSCOPED artifact lookup (ADR-0048 gap) #4624) and the retriage are on this card (6033604558, 6033665812).
