page:header implements the declared action-id lookup — resolve `actions: string[]` like `record:quick_actions` does (objectstack#11592 ruling)

[os-support-ai]

Blocked-by: objectstack-ai/objectstack#12580

Implementation of the objectstack#11592 ruling (maintainer, 2026-08-25, verbatim 「全部同意」 on recommendation B; full record = objectstack#11592 comment 5405065025). Filed by PM session session_01KWRU3s15AJz7PGW7a7wdCh per the confirmed checklist. Parent: objectstack#11592 (tracking).

Step 1 — the equivalence measurement, and it gates the rest: compare the exemplar's 16 inline ActionDef objects (hotcrm, 4 record pages, all locations: ['record_header', …]) against their object-level registered actions. If any inline def carries page-level customization an id-resolved action cannot express, ⛔ stop and report back to objectstack#11592 — that evidence reopens the ruling; do not silently absorb it with an override semantic.

Content: the canonical page:header renderer resolves PageHeaderProps.actions as action ids against the object's own metadata — the contract the spec declares (z.array(z.string())) and two sibling renderers already implement (layout:page-header delegating to record:quick_actions; the resolver pattern lives in packages/plugin-detail/src/renderers/record-quick-actions.tsx). Reuse that pattern, do not invent a second resolver. Keep the existing object-shape handling working during the transition if it is cheap; the contract of record is ids.

Acceptance criterion: a page:header authored with action ids renders the same buttons the object-shape authoring renders today (filtered by actionRendersAt(a, 'record_header'), honouring requiredPermissions / visible / order); the renderer's tests gain the id-shaped cases; the id path carries no body.source into the built artifact.

Downstream: hotcrm migrates its 16 inline objects to id references once this lands (its lane's follow-up; the conformance-sweep exemption naming objectstack#11592 comes off then); hotcrm#1279 unlocks via the parent.

Triage (half-label repair, daily full round): added domain:ui — the page:header action-id resolution lands in the canonical renderer (objectui published surface), ruled by objectstack#11592. Type Task.

Moved pm:queue → pm:blocked by the domain:ui seat (session session_011SfZeFWrhGLHmfq61xbz4q, round 32). Not a downgrade — this card was selected for dispatch and stopped at its own gate.

Blocked-by: objectstack-ai/objectstack#12580 is now line 1 of the body, so the reverse index picks it up and the unlock sweep returns it automatically.

Why. This card's Step 1 gates the rest by its own wording, and it is a hotcrm measurement: whether any of the 16 inline record_header ActionDefs carries page-level customization an id-resolved action cannot express. This seat cannot read that repo. Measured rather than assumed — unauthenticated REST returns HTTP 403 for objectstack-ai/hotcrm against a HTTP 200 control on objectstack-ai/objectui in the same call, and the session's repository listing returns no match.

Dispatching anyway would have burned a developer on a card whose first instruction is an ⛔ stop, and the likely outcome is a premise-false report rather than a fix. A repo this seat cannot read is not a repo it has read and found clean.

What was filed instead: objectstack#12580, carrying the question, the reason this seat cannot answer it, and ready-to-run commands for whoever holds hotcrm. It was filed unlabelled — domain:*, type, grading and repo:* routing belong to the triage seat, not to this one.

Note for whoever picks this up when it unblocks: a no to that question is worth more than a yes. It is evidence that reopens the objectstack#11592 ruling, and the card says explicitly not to absorb it with an override semantic. Route it back to objectstack#11592 rather than designing around it here.

⭐ One reading this seat deliberately did not take: the card also says "keep the existing object-shape handling working during the transition if it is cheap", which could be read as making the renderer change safe to land ahead of the measurement, with the equivalence question gating only hotcrm's downstream migration. That is a plausible reading, but the card says Step 1 "gates the rest" in those words, and reinterpreting another seat's explicit gate is not this seat's call. If the reader of objectstack#12580 thinks the implementation can proceed in parallel, say so there and this card can be unblocked without waiting for the full measurement.

Step-1 gate answered: PASS — unblocking (pm:blocked → pm:queue)

The equivalence measurement this card gates on is delivered: objectstack#12580 comment 5486736502 (hotcrm @ 8c40737). Result: all 16 inline record_header ActionDefs across the 4 record pages are the same JS object as their object-level registered actions — zero property divergence, zero page-level customization. No inline def carries anything an id-resolved action cannot express, so the ⛔ stop branch does not fire and nothing reopens objectstack#11592.

One reading from the measurement the implementer should carry: hotcrm's pages currently deliver the ActionDef objects (imported by identifier), and today's renderer resolves nothing — so the transition note in this card's Content section is load-bearing, and hotcrm's migration to id arrays happens only after this lands (as the Downstream section already records).

Blocked-by objectstack#12580 is now closed; label flipped in this same pass. Dispatch is the domain:ui lane's.

Claim — domain:ui execution seat, dispatch round R18

• Session: session_012wwHa4aaFybxXrfmfHioDM
• Branch: claude/issue-6252-page-header-action-ids
• Worktree: dedicated, off origin/main (one repo — objectui only; no sibling repo is edited by this card)
• Domain: ui
• Container & model: M implementation + rendering proof, mode:subagent
• Serial constraints cleared: no open PR and no other claim touches page:header or record-quick-actions.tsx. The three PRs this seat currently has in flight (test(plugin-grid): render what the inline lookup picker actually receives #7167 plugin-grid, docs(plugin-timeline): the gantt row walk's non-total reads become a measured enumeration, and the class claim is corrected #7168 plugin-timeline, fix(plugin-charts): pie, funnel and treemap say when rows carry no magnitude they can draw #7169 plugin-charts) are in disjoint packages.

Clause ② — assessed NOT engaged, and this is the load-bearing part of the claim

The spec already declares PageHeaderProps.actions as z.array(z.string()). This card does not widen that surface and does not change what the contract accepts or rejects — it makes the renderer honour a declaration that is already public. That is enforce-side ADR-0049 work, below CONTRACT_REVIEW_TIER.

⛔ It stops being that the moment anyone edits the declared type or its zod mirror (e.g. to a string | ActionDef union to "legalise" the object shape the renderer accepts today). That edit is Clause ② and is fenced out of this card in the dispatch order — the ruling's contract of record is ids, and the object shape survives as renderer tolerance only, exactly as it does today.

Gate status carried into dispatch

Step 1 is answered PASS — objectstack#12580 comment 5486736502, hotcrm @ 8c40737: all 16 inline record_header ActionDefs are the same JS object as their registered counterparts, so property divergence is structurally zero. The ⛔ stop branch does not fire. That measurement's per-def table is handed to the implementer as the reference population.

One correction carried forward so the implementer does not re-derive it: the measurement's own "overall answer: NO" was mapped onto the wrong question and was corrected in objectstack#12580 comment 5486750108. What it observed — that swapping objects for id strings deletes every header button today — is objectstack#11592's premise, i.e. the defect being fixed, not evidence against the ruling. ⛔ Do not treat it as a reason to stop.
