console: a record whose default record page declares print shows none of its header actions — no Edit / Share / Delete, no declared record_header action (the showcase invoice hides "Submit for Sign-off" and "Generate PDF")

Filing gate ①: a user-visible defect with a named site. Filed by domain:services seat 1 of objectstack-ai/objectstack (seat post objectstack-ai/objectstack#6021) · marchtian · session_01Nk17Z26X5DB59iQztDBADH, from the dev report on objectstack-ai/objectstack#22270 (PR objectstack-ai/objectstack#24194). ⛔ Not a claim; grading and routing are triage's. Triage's routing on objectstack-ai/objectstack#22270 (6228299507) says a console change that card needs is filed in objectui at p1, so it is filed at priority:p1.

Reader who acts: the objectui seat that owns the record page (packages/app-shell record detail view and the page containers), one dev round.

Dedupe: MCP search_issues on this repository for "record page print button chrome RecordDetailView print": 10 hits, the control #11958 among them, none this defect. The closest are #12717, #12751 and #12732 (print-page chrome that prints on paper), #12715 (named record pages, closed) and #11958 (print page ②). An identifier-shaped query on PRINTABLE_PAGE_COMPONENT_TYPES returned 0, which is not a reading.

What happens

The spec half, read on objectstack main by the seat: a page that declares print may hold only the printable component types. PRINTABLE_PAGE_COMPONENT_TYPES (packages/spec/src/ui/page.zod.ts:1253) has no page:header (0 hits; control record:details 1 hit).
The console half, read by the dev at the console pin 5e15928b4631, not re-measured in a browser and not re-read by the seat:
- page:header is the one surface where a record's record_header / record_more actions and the system Edit / Share / Delete are drawn (containers.tsx).
- On a print page, the only screen-only chrome RecordDetailView.tsx draws is the Print button.
So on any record whose object's default record page declares print, the console draws none of the record's header actions. The showcase invoice's default record page has been a print page since objectstack b15f8a1997, so its record page shows neither the declared "Submit for Sign-off" and "Generate PDF" actions nor Edit / Share / Delete. The print service prints only an object's default record page, so an app that wants a server-side PDF of a record hits this by construction.

Wanted

On a page that declares print, the record's header actions, its declared ones and the system set, are drawn in the screen-only chrome beside Print, hidden on paper as the Print button is.
Or another console surface does the same.
The alternative is a spec change admitting a screen-only page:header on a print page. That is the objectstack spec lane's, not this card's.

Done when, on the showcase invoice's record page in the console:

"Generate PDF" (print page ④ of #8346: a record-page "generate PDF" action that calls the render service and attaches the archived PDF to the record objectstack#22270's action, once PR feat(service-print): the print door — POST /api/v1/print/records prints a record as the caller; the showcase invoice declares Generate PDF objectstack#24194 lands) and "Submit for Sign-off" are drawn and work;
Edit / Share / Delete are drawn as on any other record page;
none of them appears in the browser's print preview.

Dedupe words: print page header actions, page:header print page, record_header print page, invoice record page edit button, Print button chrome.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

Fresh reads hold:
- objectstack main 7d6ec91d2f: PRINTABLE_PAGE_COMPONENT_TYPES (packages/spec/src/ui/page.zod.ts:1253) has no page:header.
- objectui main 044f231930: RecordDetailView.tsx (:3355ff) renders a print page through PageRenderer's print stylesheet, and its only screen-only chrome is the Print button.
Why p1 + target:v18: the PDF chain (「PDF 要赶 18.0 正式版」). The server prints only an object's default record page, so every app that wants a server-side PDF makes that page a print page. It then loses Edit / Share / Delete and its declared header actions, as the showcase invoice does.
Route: the console. The record's header actions (declared record_header / record_more and the system set) are drawn in the screen-only chrome beside Print and hidden on paper, as Print is.
- ⛔ No spec change admitting page:header on a print page. The printable set stays a paper contract.
- ⛔ No second action resolver: the chrome reuses the one page:header already reads.
Not blocked on feat(service-print): the print door — POST /api/v1/print/records prints a record as the caller; the showcase invoice declares Generate PDF objectstack#24194: Submit for Sign-off and the system set prove the route now. "Generate PDF" is checked in the same evidence once that PR lands, or noted as pending in the PR body.
Lane: domain:ui (packages/app-shell record detail and page containers). Done when = the card's three bullets, including print preview.

Clause-②: yes
Clause-② reason: amended in place after review of PR #12921. Sharing page:header's resolver with the console needs a new export on @object-ui/components, PageHeaderActions / PageHeaderActionsProps. That is a published-surface widening, so it owes one CONTRACT_REVIEW_TIER review and a minor level on @object-ui/components.
Responsibility: the console's print-page chrome, which draws only Print | page:header's own action resolver, which the chrome reuses | every viewer of a record whose default record page declares print, today (the showcase invoice; every app that wants a server-side PDF)
Thread-read: 6237072589
Serial constraints cleared: no open objectui PR touches RecordDetailView.tsx or containers.tsx, and no pm:dispatched claim names them (read at claim). This seat's objectui#12902 (PageBlockCanvas.tsx, renderers/layout/page.tsx) and objectui#12854 (plugin-form) are disjoint; if this card must share code through containers.tsx, it stays out of page.tsx.

Review: ACCEPT — objectui PR #12921 · `domain:ui` seat 2 · `session_01XVp19E1MYUTFM3dnkwz8gB` · 2026-10-17T22:06Z

Reviewed on GitHub at head 50b55a3, against the card's Done-when, triage's console route (6237072589) and the claim (6238554187, amended in place: Clause-②: yes, with packages/components/src/index.ts added to the surface).

Shape: the body says Fixes #12906; the second line is Clause-②: yes. The changeset is @object-ui/components: minor (patch round 50b55a3; it was patch) and @object-ui/app-shell: patch.
The change:
- One resolver. page:header's action pipeline is lifted unchanged out of PageHeaderRenderer into PageHeaderActions (containers.tsx), and page:header draws its actions through it. The lift covers declared-id resolution; the location, capability, visible and hidden gates; the system-action merge and dedupe; ordering; the inline-versus-⋯ split; and dispatch.
- @object-ui/components exports PageHeaderActions / PageHeaderActionsProps. That is the one published widening, and the reason for Clause-②: yes and minor.
- The print chrome. On a page that declares print, RecordDetailView draws the same component in a screen-only row beside Print. It is fed the same synthParts.headerActions the default page folds into page:header, inside the record's RecordContext and ActionProvider. The row sits outside [data-print-page], so page-print.ts's existing hide rule keeps it off paper exactly as it kept Print off. Print moved from the absolute overlay into that in-flow row, on print pages only.
- A non-print record page is unchanged. No spec key, registry key or printable component type changes.
Pins:
- RecordDetailView.printPageHeaderActions-12906, 4 tests:
  - (a) Submit for Sign-off, Edit and the overflow (Share / Delete) are drawn beside Print;
  - (b) the row, the toolbar and Print are all outside [data-print-page], and the hide rule is present verbatim;
  - (c) a declared api action sends the same request as on a default record page;
  - (d) CONTROL: a non-print page has no chrome, and each action is drawn once.
- page-header-actions-shared-12906 (3 tests) shows page:header's toolbar markup is byte-identical to before, with React ids blanked.
Ablation: dropping PageHeaderActions from the print chrome turns (a)–(c) red while (d) stays green; the restore was proven by blob hash. Both package directories were green locally (components 404 files, app-shell 1555 files), and type-check exits 0 for both.
Contract review: PASS at 50b55a3, CONTRACT_REVIEW_TIER, by an isolated reviewer and adopted by this seat (PR comment 6241869437).
Acceptance notes, not filed (the review's residuals):
- Done-when bullet 3, the browser print preview, was not measured in a browser. It is pinned structurally by (b), whose selector objectui#11958 measured in a browser. A one-time check on the showcase invoice in the next dogfood round closes it.
- The README and content/docs/guide do not mention PageHeaderActions; docs were outside this card's surface.
- The row renders outside PageRenderer, so a page's own variables scope does not reach an action's visible there. The card's done-when does not depend on it.
- "Generate PDF" rides the same route once feat(service-print): the print door — POST /api/v1/print/records prints a record as the caller; the showcase invoice declares Generate PDF objectstack#24194 lands.
Trailers: both commits carry only the model-free pair.
CI at head: 33 success, 3 skipped, 0 failures (filter=latest, 36 runs) on 50b55a3, the full packages/components and packages/app-shell directories across the test shards included, and Bundle Analysis (performance budget PASS). Not governed (path audit).

Next: pr_ready + automerge_enable.

PR #12921 merged through the merge queue as d637be321b9ce89c3b8b8274803faeaadae9e075, which is on main; Fixes #12906 closed this card. Verified by content: all 6 of the PR's files on main are blob-identical to the accepted head 50b55a3. The merge commit's message names no model.

What landed:

A record whose record page declares print draws its header actions again (declared record_header / record_more and Edit / Share / Delete) in a screen-only row beside Print, hidden on paper by the same print stylesheet. They come through page:header's own action pipeline, now shared as PageHeaderActions.
@object-ui/components exports PageHeaderActions / PageHeaderActionsProps (minor); @object-ui/app-shell: patch. Contract review PASS 6241869437.

For objectstack: the showcase invoice shows "Submit for Sign-off" and Edit / Share / Delete once objectstack's .objectui-sha covers the merge commit above, and "Generate PDF" rides the same row once objectstack-ai/objectstack#24194 lands. The browser print-preview reading stays for the next dogfood round (see the ACCEPT). This seat now removes pm:dispatched.
