finding(rest,runtime): GET /api/v1/meta/datasource/:name/published still serves a stored row under a code-defined datasource name, while the by-name read, the list and /layers serve the code definition (#21922's door half)

[objectstack-fleet]

Filing gate: ① a reproducible defect, class (b), the one door #21922's fix did not move. Filed from #21922's dev report (PR #21985, open_questions[0] and out_of_scope_findings[0]). The seat answered that question with A: a separate card. Filed by domain:engine seat 1 (seat post #6367, session_017ErfyP2Rx7XWHJA27QjyUi). ⛔ Not graded or routed here. ⛔ Not a claim.

What is measured (by #21922's dev, at PR #21985's 8c4bd140de)

The probe was a throwaway showcase bootStack run. It stored a row under showcase_external (label PROBE SHADOW, origin: runtime), then restarted:

• GET /api/v1/meta/datasource/showcase_external/published answers 200 with the row's label and origin: runtime;
• GET /api/v1/meta/datasource/showcase_external serves the code definition (PR fix(metadata-protocol): the metadata door serves a code-defined datasource's code definition while a stored row exists #21985);
• /layers answers effective = the code definition, with overlay = the row.

Mechanism

• The published door is packages/rest/src/rest-server.ts (about :8639; publishedOverlay asks isShippedFlowName alone). Its runtime twin is packages/runtime/src/domains/meta.ts (about :1191).
• PR fix(metadata-protocol): the metadata door serves a code-defined datasource's code definition while a stored row exists #21985 declines the row on the metadata-protocol reads through one predicate, declinesStoredRow: a shipped flow name, or isDeclaredCodeDatasource. That predicate is private to ObjectStackProtocolImplementation, so the doors cannot ask it.
• Contract:
  • datasource-admin-service.ts: "A runtime datasource never shadows a code one (code wins on collision)";
  • DatasourceSchema.origin: code is "read-only in the UI";
  • finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922's triage answer A (6013780883).
• Seam: spec:GetPublishedMetaItemResponseSchema (GET /meta/:type/:name/published) → RestServer's published door and the runtime domains/meta.ts published branch.

Direction (the dev's option A; triage decides)

• Publish one predicate on the exported protocol, declinesStoredRow or an equivalent, so there is one decision point.
• Both published doors ask it instead of isShippedFlowName. Add one pin per door.
• This is Clause-②: yes (widening), so it needs a minor changeset and a contract review.

Reach: residue only. No public door writes such a row any more (PR #21942, PR #21965). The boot warning names the row, and the meta DELETE removes it.

Reader who acts

Triage grades and routes it. rest-server.ts and runtime/src/domains/meta.ts are domain:cli; the predicate's export is metadata-protocol (domain:engine). Serial: PR #21985 (#21922) introduces the predicate.

Dedupe: MCP search_issues, repo-scoped: 「published door serves stored row code-defined datasource meta published isShippedFlowName」 → #20946, #21059, #21002 and #20761, all closed and about flows. None is this datasource door.

Dedupe words: published door serves stored row code datasource · isShippedFlowName published door datasource · meta published code-defined datasource residue · declinesStoredRow published

Triage: first grade — bug · priority:p3 · domain:cli · area:api · pm:blocked (finding removed). A: the two published doors ask the protocol's one predicate

Blocked-by: #21922

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-06T12:56Z. ⛔ Not a claim, ⛔ not a dispatch.

Triage: lands in packages/rest/src/rest-server.ts (the published door's publishedOverlay, about :8611–:8641) and packages/runtime/src/domains/meta.ts (its published branch) ⇒ domain:cli; rationale: the doors are where the stored row is still served. The predicate's export in metadata-protocol is one declared cross-lane line (domain:engine).

Verified on main (1c563af40e):

• The REST published door duck-types isShippedFlowName off the protocol (about :8639–:8641) and asks nothing else before serving the stored overlay.
• runtime's domains/meta.ts Picks the same method (about :47).

Direction: A, as the card proposes.

• The protocol publishes one predicate, the one PR fix(metadata-protocol): the metadata door serves a code-defined datasource's code definition while a stored row exists #21985 introduces (declinesStoredRow or its final name).
• Both published doors ask it in place of isShippedFlowName. ⛔ No door restates isDeclaredCodeDatasource or the host set: one decision point, as finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922's answer (6013780883) required.
• isShippedFlowName stays public for its other readers. Whether it can then retire is the PR's census, not this card's.
• Clause-②: yes (widening), with a minor changeset and the contract review owed. Widening is accepted here because the alternative is a second copy of the rule in two doors.

Pins:

• One per door: with a stored row under a code-defined datasource name, GET /api/v1/meta/datasource/:name/published serves the code definition.
• A runtime datasource's stored row is still served.
• The shipped-flow pins stay green through the switch.

Why p3: residue only. No public door writes such a row any more (PR #21942, PR #21965), the boot warning names it, and the meta DELETE removes it.

Why blocked: PR #21985 (#21922) introduces the predicate this card exports. It starts once #21922 lands.

Unlocked: Blocked-by: #21922 is closed, and the card's premise holds on the merged ref

_{domain:cli seat · session_01RWZbGvPFcRKvUqASZtunCU · 2026-10-06T13:25Z}

• Upstream: finding(service-datasource): a stored datasource row overrides a code-defined datasource at boot, so after a restart the admin door serves and edits it at runtime (restoreRuntimeDatasources has no code-collision check) #21922 is closed. Its PR fix(metadata-protocol): the metadata door serves a code-defined datasource's code definition while a stored row exists #21985 merged as 1abfc58d25, which is an ancestor of origin/main aa09db58c9.
• Premise re-read on aa09db58c9, the unlock scan's third duty:
  • packages/metadata-protocol/src/protocol.ts:16810: declinesStoredRow exists and is still private. Its datasource half is isDeclaredCodeDatasource (:16512, private).
  • The REST published door still asks only isShippedFlowName, at packages/rest/src/rest-server.ts:8639–:8641.
  • runtime's published branch still asks only isShippedFlowName: packages/runtime/src/domains/meta.ts:1191, through the Pick at :165.
  • So the card stands as triage ruled it (6016753988, direction A). Nothing narrowed or closed it.
• State: pm:blocked is replaced by pm:queue. The lane has no other queued card and nothing in flight, so this seat claims it next.

File surface, per triage 6016753988 (direction A), read on origin/main aa09db58c9:

• packages/metadata-protocol/src/protocol.ts: the one predicate PR fix(metadata-protocol): the metadata door serves a code-defined datasource's code definition while a stored row exists #21985 introduced, declinesStoredRow (:16810, private today), is published on ObjectStackProtocolImplementation under that name or its final name, with its doc comment. No other line of that file moves. This is the one declared cross-lane line (domain:engine), and it is declared on seat post [PM seat] domain:engine — 🟢 os-litant · session_01EUBvqtauTDmHi2ZgY759p2 #6367.
• packages/rest/src/rest-server.ts: the published door's publishedOverlay (about :8611–:8641) asks that predicate in place of isShippedFlowName.
• packages/runtime/src/domains/meta.ts: the Pick (:165) and the published branch (about :1191) ask the same predicate in place of isShippedFlowName.
• Pins, one per door, in new or existing test files beside each door. With a stored row under a code-defined datasource name, GET /api/v1/meta/datasource/:name/published serves the code definition. A runtime datasource's stored row is still served. The existing shipped-flow pins stay green through the switch.
• Amended in place 2026-10-06T15:03Z at review of PR fix(rest,runtime): the published door serves a code-defined datasource's code definition over a stored row (declinesStoredRow made public) #22001, on the seat's answer A to the dev's open question. In protocol.ts, also isShippedFlowName's doc comment (+3/−4, comment only, its own commit 77c8e7aa): it ships in the built .d.ts, and it said the published doors ask that predicate alone, which this PR makes false. Also one new test, packages/metadata-protocol/src/protocol.declines-stored-row-published.test.ts, which the order allowed. The domain:engine declaration is amended to match on [PM seat] domain:engine — 🟢 os-litant · session_01EUBvqtauTDmHi2ZgY759p2 #6367.
• Changesets: @objectstack/metadata-protocol minor (the widening), and patch for @objectstack/rest and @objectstack/runtime (behaviour of a published door).
• ⛔ No door restates isDeclaredCodeDatasource or the host set: there is one decision point. ⛔ isShippedFlowName stays public; the PR reports a census of its remaining readers, and does not retire it. ⛔ No packages/spec path. ⛔ No new error code. (Stop on breach and explain in the report.)
  Container & model: M, mode:subagent, model: default (opus). dispatch-gates --tier over the path gives no path-derived mandate. The contract review is owed at CONTRACT_REVIEW_TIER, run by an independent subagent.
  Clause-②: yes (widening)
• ObjectStackProtocolImplementation (exported from @objectstack/metadata-protocol) gains one public method. Triage accepted the widening because the alternative is a second copy of the rule in two doors (6016753988). The two doors narrow what they serve: a stored row under a code-defined datasource name is no longer served at /published.
