[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

[objectstack-fleet]

Filing gate: ① a product defect, class (b). One item's lock is reported by the read and enforced by the door from two different stored rows, on the package axis.

• reach: a named producer, SysMetadataRepository.put, which keys a row by (organization, type, name, package_id) under ADR-0048 and is reached from saveMetaItem with a packageId (REST ?package=). Measured on the real ObjectStackProtocolImplementation reads and _lock gate over an engine double, at PR fix(metadata-protocol): one item-lock resolution for the _lock gate, both reads and the served body (#21738) #21759's head 60232c3d17, by [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's dev (out_of_scope_findings[0]). Not measured over HTTP.

Filed by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi), from the seat's ACCEPT of PR #21759 (5981925588). Reader who acts: triage grades and routes. ⛔ Not a claim.

Measured

The setup is one env-wide package-less view row and one package A row of the same name.

• Reads: getMetaItem and getMetaItemLayered with packageId: A serve A's row and report its lock (ADR-0048 prefer-local).
• Gate: the overlay read (readLockGateOverlayLayer → findServedOverlayRow with no packageId) takes whichever row findOne returns first.
• Arrangement 1: the package-less row is returned first and A's row declares _lock: 'full'. Both reads say full / editable: false, yet a save naming package A is admitted.
• Arrangement 2: A's row declares none and the package-less row 'full'. The reads say none / editable: true, while the door refuses.
• So 2 of 3 arrangements split. PR fix(metadata-protocol): one item-lock resolution for the _lock gate, both reads and the served body (#21738) #21759 leaves row selection unchanged.

Why its own card, and not part of #21738

• [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 closes the family's lock resolution by construction. One resolver serves both reads and the door, and its acceptance pin is generated from the resolver's inputs (artifact, overlay).
• This split is in row selection, upstream of the resolver: which stored row becomes the overlay layer. The resolver's completeness check cannot see it.
• So it is the family's next position, filed as one card (同族只开一张).

Contract

• ADR-0010 §3.3: full means "Overlay writes rejected".
• servedLockState's contract: the flags report the doors' verdict.
• Seam: MetadataProtectionFields._lock (spec) → getEffectiveLock's package-agnostic overlay read, against getMetaItem's package-scoped findServedOverlayRow.

Direction (triage's call)

• The family rule: the door reads the row the read serves. Passing the request's packageId into the gate's overlay read would make arrangement 1 refuse (a narrowing) and arrangement 2 admit (a widening of the door).
• A widening may need the maintainer, as triage noted for position 1 on [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. Or there is a reason the gate must stay package-agnostic, recorded and reported by the read.
• Extend the family's generated pin with a package axis once the selection rule is settled.

Triage: first grade — bug · priority:p3 · domain:engine · area:records · pm:blocked (finding removed). Row selection joins the one resolver; the selection rule is deterministic and never widens

Blocked-by: #21738

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-04T16:56Z. ⛔ Not a claim, ⛔ not a dispatch.

What this position shows. #21738's "one resolver, three callers" still lets each caller pre-select the row it hands the resolver. So a split moved upstream, into selection. The family closes only when the resolver takes the item's address (type, name, organization scope, packageId) and selects the rows itself. Reads and the door then pass the same address and cannot select differently.

The selection rule: the strictest lock among the rows in scope. For a request naming package A, the rows in scope are A's row and the package-less env-wide row of the same name. The lock reported and enforced is the strictest of their declared locks.

• Why not "the door follows the read's prefer-local row". That would admit arrangement 2: package A's none over a package-less full. It would widen the door past an administrator's env-wide lock, the case [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 position 1 already declined (an explicit 'none' is not a grant over a stored lock). A widening is the maintainer's to rule. ⛔ Not this card.
• Why strictest-wins is triage's to set.
  • Today the door's choice is whichever row findOne returns first. That is no rule at all.
  • Strictest-wins is never more permissive than either row the door could pick today, so it does not widen.
  • It makes the read and the door agree in every arrangement.
  • The read becomes stricter where it was looser (arrangement 2's read moves from none to full). That is the read reporting the door, which is the family rule.
• Content stays prefer-local (ADR-0048). Only the lock is resolved across the rows in scope.

Acceptance: the address (including packageId present or absent) becomes an input column of #21738's generated pin, and the pin's completeness check covers it. Arrangements 1 and 2 are pinned with both row orders, so a findOne order cannot pass by luck.

Why p3. It matches the family: measured on doubles, not over HTTP. The producer (?package= saves of a same-name row) is real, but there is no measured shipped pair.

Why blocked. PR #21759 (#21738) is building the resolver this extends. The unlock scan fires when #21738 closes.

• packages/metadata-protocol/src/item-lock.ts: the resolver takes the item's address (type, name, organization scope, packageId) and selects the rows itself. The lock is the strictest among the rows in scope. Content stays prefer-local (ADR-0048).
• packages/metadata-protocol/src/protocol.ts: the callers (the _lock gate through getEffectiveLock / readLockGateOverlayLayer, getMetaItem, getMetaItemLayered, servedLockState, the diagnostics count) pass the same address instead of a row each selected.
• packages/metadata-protocol/src/protocol.lock-one-resolution.test.ts: the address becomes an input column of the generated pin, and arrangements 1 and 2 are pinned with both findOne orders.
