[finding] lock family, artifact layer × package axis: the _lock gate looks up the packaged artifact with no package while both reads look it up with the request's package #21803

Triage: first grade — bug · priority:p3 · domain:engine · area:records · pm:blocked (finding removed). The artifact layer takes the family's rule, and this card is the lock family's closing card

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-05T03:06Z. ⛔ Not a claim, ⛔ not a dispatch.

Blocked-by: #21761

Triage: lands in the _lock gate's artifact limb (getEffectiveLock → lookupArtifactItem) ⇒ domain:engine; rationale: the reads and the door look the artifact up two different ways, so one item has two lock answers.

• Direction (triage's call, as the card asks). The artifact layer takes the rule [finding] lock family, package axis: a read naming a package serves that package's row and reports its lock, while the _lock gate's overlay read selects without a package #21761 set for stored rows (5982313964): the strictest lock among the installed packages that ship the name, never a widening. The gate and both reads take it from one resolution.
  • ⛔ No prefer-local artifact lock at the door. It would admit a save that another installed package's lock refuses.
• Closing card. This is the family's sixth position ([finding] The layered metadata read reports lock none, editable true and deletable true for packaged flows and actions that the write doors refuse with NOT_OVERRIDABLE #21670, finding(metadata-protocol): two lock reports the #21670 read fix left unaligned — a host-config kernel's _lock gate admits a save the read now calls non-editable, and getMetaDiagnostics().stats[type].locked counts declared _lock only #21694, [finding] an env-wide metadata row declaring _lock: full reads locked in an org-scoped read, but an org-scoped save of it is admitted — getEffectiveLock's overlay limb matches organization_id exactly #21716, [finding] lock family, artifact-layer axis: an explicit artifact _lock: 'none' reads editable while the door refuses, and the layered read takes the code layer's lock over a stored row's #21738, [finding] lock family, package axis: a read naming a package serves that package's row and reports its lock, while the _lock gate's overlay read selects without a package #21761, this card). The PR therefore adds an enumeration pin: one matrix test over the family's positions (artifact layer and stored rows × topology, organization and package axes) that asserts, for each, that the read's reported lock equals the door's verdict. A new position then fails that test instead of arriving as a seventh card.
• Why p3. It needs two installed code packages that ship one name. It fails closed: the door is stricter than the read. The siblings were p3.
• Why blocked. PR fix(metadata-protocol)!: an item's lock is the strictest lock among the stored rows in scope for its address (#21761) #21801 ([finding] lock family, package axis: a read naming a package serves that package's row and reports its lock, while the _lock gate's overlay read selects without a package #21761, pm:dispatched) is reworking the same resolver. This card starts on its landing.

One more measured position for this closing card — domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi), at 2026-10-05T04:57Z. For triage, to fold or not. ⛔ Not a claim.

Measured by #21804's dev on the engine double, identical at 18c2ddc1ec and at PR #21815's head (out_of_scope_findings[0]). Not over HTTP.

Arrangement.

• The organization holds only package B's row of view/v.
• An env-wide row of package A declares _lock: 'full'.
• getMetaItem({ type: 'view', name: 'v', organizationId: 'org_a', packageId: 'com.a' }) is called.

What is served.

• The envelope says lock: 'none', editable: true.
• The served body is env A's row, and it carries _lock: 'full'.

Why they split. The content scope and the lock scope are resolved differently.

• Content: findServedOverlayRow looks in the organization first and finds no row of A and no package-less row there, so it serves the env-wide row of A.
• Lock: resolveOverlayLockLayer takes the organization's rows whenever the organization holds any row of the item. Here that is B's row, which declares no lock.
• withOverlayLockFamily leaves the body untouched when no overlay row binds, so env A's _lock: 'full' survives.

Contract it breaks: item-lock.ts's header, "a body never states a lock the envelope does not report". The door agrees with the envelope (it admits), so it is the body that disagrees.

Why here: it is the lock family again, at the seam between content scope and lock scope. This card is the family's closing card, and its enumeration pin is the place a position like this should fail.

Dedupe words: served body _lock envelope none, withOverlayLockFamily non-binding body, organization holds another package row, content scope vs lock scope.

File surface (at origin/main c4d57131b5), per triage's direction 5987395126, which the unlock 5987813232 restates:

• packages/metadata-protocol/src/item-lock.ts and protocol.ts: the artifact layer takes [finding] lock family, package axis: a read naming a package serves that package's row and reports its lock, while the _lock gate's overlay read selects without a package #21761's rule. The lock is the strictest among the installed packages that ship the name, never a widening, from one resolution shared by the _lock gate's artifact limb (getEffectiveLock → lookupArtifactItem) and both reads.
  • ⛔ No prefer-local artifact lock at the door.
• The family's enumeration pin: one matrix test over the family's positions (artifact layer and stored rows × topology, organization and package axes), asserting for each that the read's reported lock equals the door's verdict.
• The position the seat folded in (5988387087, a served body's _lock against its envelope where the content scope and the lock scope part) is measured under that pin. A fix that needs a ruling stops and reports.
• Tests; .changeset/21803-*.md.
  Container & model: M, mode:subagent, model: default (dispatch-gates --tier: no path-derived mandate).
  Clause-②: no (narrowing)
• Where the door bound a looser packaged lock by registration order, it now binds the strictest among the installed packages that ship the name. That enforces a lock already declared and widens nothing. No accepted key, export, status or error code changes.
  Thread-read: 5988387087
  Serial constraints cleared: at 2026-10-05T06:14Z:
• Triage's serial predecessor [finding] getMetaItems: a package's list slot can serve the package-less row's body while getMetaItem naming that package serves the package's own row #21804 landed as PR fix(metadata-protocol): a package's list slot serves the stored row getMetaItem naming that package serves, in every row order (#21804) #21815 → 3237b4a2d9.
• Of the open PRs, none touches packages/metadata-protocol/src/protocol.ts or item-lock.ts (each PR's file list read by filename).
• This lane's queued sibling [finding] getMetaItems scoped to a package reads only that package's rows, so it never falls back to the package-less row that getMetaItem naming the package serves #21817 is in readFlattenedMetaItems, beside this card's list-item lock. It is held until this card lands, not claimed beside it.
• This lane's other claim, metadata: publishing a field reorder from the object designer is a silent no-op — the content hash is key-order-insensitive, so a reordered fields map hashes equal and the draft is dropped #21790 (PR fix(metadata-core): a reorder of an object's fields is a content change, so the designer's publish is no longer dropped (#21790) #21814, in the merge queue), holds canonicalize.ts and sys-metadata-repository.ts.

Every caller (the _lock gate, getMetaItem, getMetaItemLayered, the list items, the diagnostics tile) now takes the artifact layer from one selection, resolveArtifactLockLayer over shippedArtifactsOf (every installed package that ships the name, a disabled one included, enumerated from existing registry methods with no new public surface), and resolveItemLock binds the strictest PER-PACKAGE answer (each package's artifact over the stored rows, first binding layer, as before). H3 taken literally (strictest artifact layer, then first binding layer) was falsified by H4 because it widens one cell, so the route was switched per the ruling's 'never a widening'. H4 on the real registry: 0 widenings, 416 narrowings, order-dependent verdicts 416/1000 pairs to 0/1000.
