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

[objectstack-fleet]

Filing gate: ① a reproducible defect, class (a), by-name read provenance: two read doors answer the same address with different package identities. It is filed from #22024's dev report (PR #22055, open_questions[0], comment 6031073024), by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi). The seat took the dev's option C: PR #22055 leaves the layered read unchanged, and its selection goes to its own card. ⛔ Not graded or routed here; ⛔ not a claim.

What is measured (by #22024's dev, at PR #22055's head 96059eb740)

• Setup: two packages ship a view container task, pkg_b stores a copy, and pkg_a registers first. Read with no package named.
• getMetaItemLayered (/layers): code is pkg_a's shipped item, and effective._packageId is pkg_b. The top-level packageId / provenance, read off code ?? overlay, say pkg_a.
• getMetaItem, with PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055: the top-level packageId says pkg_b, the package of the body it serves.
• On base, both reads said pkg_a. So PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055 makes the by-name read and effective agree, and the two top-level packageIds disagree.

Mechanism

• getMetaItemLayered's code layer is lookupArtifactItem(request.type, request.name, request.packageId) (about :10764 at 8caa131e52). With no package named, that is the first composite: the first-registered package's artifact.
• In the layered read the envelope IS the code layer's body, so the call's disposition in PR fix(metadata-protocol): a by-name read naming no package wears the envelope of the package whose body it serves #22055's enumeration is "no" by the card's graft test.

The choice (for triage; the dev's options, verbatim in the report)

• A. Scope the code layer to the served row's or expansion's package when no package is named, so the no-package layered read equals the layered read naming that package. Cost: this moves the code layer's body, which is Studio's diff baseline and reset reference for shared names. It needs the overlay read before the code read.
• B. Leave it. The code layer is the no-package code layer, which is what the no-package read serves once the overlay is removed. Cost: the two reads' top-level packageId can differ for a shared name read with no package.
• The dev's reading: this is a p3 in-process divergence, not a data-disclosure class. Moving a layer's body needs its own ruling.

Reader who acts

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

Dedupe: MCP search_issues, repo-scoped: 「getMetaItemLayered layered read code layer no package shared name first registered package」. It returns #22024, #21059, #21002, #21817, #21804, #20507, #20478 and #5707. They are about a stored flow reported as the code layer, the effective layer of a shipped flow name, list slots, the absent-name oracle, the dispatcher's envelope and a bare catch, not the code layer chosen for a shared name with no package. None is this.

Dedupe words: layered read no package code layer first registered package shared name · getMetaItemLayered top-level packageId differs from getMetaItem · layers code layer lookupArtifactItem without package

Triage: first grade, bug · priority:p3 · domain:engine · area:api · pm:blocked, folded into the closing card #22057 (finding removed). Default reading: B

Blocked-by: #22057

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-07T04:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/metadata-protocol/src/protocol.ts (getMetaItemLayered, :10562 on main) ⇒ domain:engine; rationale: the same file and family as #22024 and #22057.

• Why p3 and folded: this is an in-process divergence of two top-level packageIds for a shared name read with no package. There is no reach:, and it is not a disclosure class, as the dev also reads it. The rule for findings without reach is: p3, fold into a closing card, ⛔ not dispatched alone, ⛔ not closed for lacking reach. 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 #22057 is that closing card for the family.
• The choice, answered as a default rather than ruled:
  • B: the layered read keeps the no-package code layer, which is what it serves once the overlay is removed.
  • A would move the code layer's body, which is Studio's diff baseline and reset reference. That needs its own ruling, and nothing measured asks for it.
  • What would reopen it: 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 #22057's enumeration measures a reader (Studio, or a client) that reads both top-level packageIds for one address and acts on the difference. A decision card follows only then.
• When 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 #22057 closes, this card is re-read: either it is closed with 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 #22057's disposition line naming it, or it restarts with the measured reader as its reach:.

• The closing card landed: PR fix(metadata-protocol): a row bound to one package is not registered under a name another package ships #22066 merged as ae97841556, and 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 #22057 closed completed at 2026-10-07T10:46Z. Its landing note is 6036314621.
• B, measured twice: 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 #22057's dev answered H4 in both rounds (6033550720, 6035868703): no reader consumes both top-level packageIds for one address.
  • In objectstack, the REST /layers door serves the layered answer alone, and plugin-security reads only the code and effective layers.
  • In objectui, no reader of getMetaItem's packageId reads the same address.
  • So the layered read's code layer stays the no-package code layer, and getMetaItemLayered is unchanged on main.
• Why not A: A moves the code layer's body, which is Studio's diff baseline and reset reference for a shared name. That is a ruling of its own, and no measured reader asks for it.
• To reopen: a reader measured to consume both top-level packageIds for one address and to act wrongly on the difference. Then A goes to the decision box with that measurement.
