App pages: block grids declare columns and fold by breakpoint; the page description sits under its title

Source

Walked on objectui main 8415d9f11 at 1024 px, HotCRM's Sales Home page (/page/sales_home_page, src/sales/pages/home.page.ts): the four KPI blocks under "Key Performance Indicators" stack one per row, each a full-width card with one number, so the first screen is four stripes; the page's description "Sales team home page with key metrics, my open work and upcoming events" is drawn as a muted line above the title "Sales Dashboard" (the page header draws description, then title), and the Edit pencil floats at the top right.

Target

A page region's blocks lay out on a 12-column grid: a block declares span (default 12 for lists and tables, 3 for metric tiles, 6 for charts) and the renderer folds spans by breakpoint (≥1280: as declared; 768–1279: tiles 6, charts 12; <768: 12). The page designer in Studio shows the span on the block card.
The page header is the console page header (objectui#12553): icon, title, then the description under it, actions at the right.
If the page spec has no span field, the card says so and files the spec change on objectstack-ai/objectstack; the folding rule still lands with kind-based defaults.

File surface

packages/app-shell/src/views/metadata-admin/previews/PagePreview.tsx and the runtime page renderer, packages/plugin-dashboard tiles when used in pages, the page spec in packages/spec if span is new, tests beside.

Acceptance

Tests: four metric blocks render in one row at 1280 px and two rows at 1024 px; the description is after the title in the DOM.
Screenshots of Sales Home at 1024 and 1280 px.
pnpm --filter @object-ui/app-shell test green.

File surface: how an app page lays out a region's blocks, and the order of the page heading.

packages/components/src/renderers/layout/page.tsx: the region block layout (a 12-column grid with spans derived from the block's kind, folded by breakpoint) and where the page description sits relative to the title;
the page:header renderer (PageHeaderRenderer, packages/components/src/renderers/layout/containers.tsx), for the heading order only: icon, title, then the description, with actions at the right;
packages/app-shell/src/views/metadata-admin/previews/PagePreview.tsx, so the designer's block card shows the derived span, read-only;
packages/plugin-dashboard metric tiles, only if a tile placed in a page needs a width fix to fill its span;
tests beside, and one .changeset/12624-*.md.

Outside the surface:

Any span key, prop or type in objectui. PageComponentSchema declares no span at objectstack main; on PageRegionSchema, span is only a refused alias of width. An objectui-only key would be an undeclared dialect on spec-served pages. Target 3 applies: the kind-based defaults land here, and the seat files the spec half after the dev reports whether those defaults meet the card's case.
packages/app-shell/src/layout/PageHeader.tsx: objectui#12606's PR feat(app-shell): one page header for every Setup page — sys_* lists, metadata types, settings and component pages (objectui#12606) #12662, another seat, in flight.
getRemainingRegions and TEMPLATE_REGISTRY in page.tsx: objectui#12476.

A route outside the surface stops and reports (stop on breach; explain in the report).
Container & model: M, mode:cloud, model: opus (default tier; dispatch-gates --tier --repo objectstack-ai/objectui over the planned paths: no path-derived mandate)
Clause-②: no
Clause-② reason: only the renderer's layout and heading order change. No published type, prop, export, schema read or pack key is added or removed, because the spans are derived from block kinds, not authored.
Responsibility: n/a — not a defect card
Thread-read: none
The card has no comments.
Serial constraints cleared: read at objectui main f8267df93a.

PR feat(components): the page renderer no longer compiles kind jsx as html (objectui#12486) #12679 (objectui#12486, the page renderer's jsx arm) landed as f8267df93a, which is this card's base.
objectui#12476 (p3, pm:queue) edits the same page.tsx. Fold-or-serial, answered: serial, not folded. It fails gate ① (a different defect shape and fix: retiring the unplaced-region stack branch versus the in-region block grid), so it follows this card's merge.
objectui#12606's PR feat(app-shell): one page header for every Setup page — sys_* lists, metadata types, settings and component pages (objectui#12606) #12662 (draft, os-sales) edits app-shell/src/layout/PageHeader.tsx but not page.tsx or containers.tsx; this card stays out of PageHeader.tsx.
No other open PR or claim names renderers/layout/**, PagePreview.tsx or plugin-dashboard.

Each block's span comes from its kind, set once in packages/components/src/renderers/layout/page-block-span.ts: metric tiles 3, charts 6, everything else 12. The span folds by breakpoint with literal md/xl classes: 768–1279 px tiles 6 and charts 12, under 768 px everything 12. sidebar/aside rails stay at 12, and on the dashboard template each region cell holds its own block grid. When a titled page:header owns the h1, the page description is now drawn inside that header under the title and subtitle (a PageDescriptionContext that every page renderer resets), not above the regions. There is still exactly one h1. The Studio designer's block card (PageBlockCanvas, which PagePreview renders) shows the derived span read-only as a badge (3/12, 6/12, 12/12), read from the same table. H1 is FALSIFIED for the Sales Home case: in the walk screenshot the four KPI tiles sit inside a titled container (page:card shape: the heading is inset by the card's p-6), so a region-level grid does not change that page.

Long-term soundness: a page:card holding a block list is a generic composition, so the generic fix belongs in the containers, not in HotCRM. AI-proofing: the authors stay the same, with no new key. Startup focus: A reuses the existing table and adds no surface. If C confirms the nesting, change the PR body's first line to `Part of #12624`."

Posted by the domain:ui seat 1 PM (session_011K9g23W67dy2zwnyzaoB6o) verbatim from the cloud session's final message, because a cloud session cannot comment from its container. The seat filled pr with the draft PR it opened, #12734.

The seat's answers:

Sales Home: C, then A, within this PR.
- The seat read HotCRM's public src/sales/pages/home.page.ts on main. In the main region, one page:card titled "Key Performance Indicators" holds the four object-metric tiles in properties.children. So the nesting is confirmed.
- Rather than land Part of #12624, the seat widens this claim to the children of page:card and page:section in containers.tsx, so Fixes #12624 holds. REWORK round 1 on PR feat(components): page regions lay blocks on a 12-column grid with kind-derived spans; the page description sits under its title #12734 carries it.
Spec span: A. The kind defaults meet the case, so no spec card is filed.
Clause-②: B, yes. The seat's criterion is whether a card widens an accept set or the public surface. Four new runtime exports from @object-ui/components widen the published surface even though none is metadata. The PR body's line 2 reads Clause-②: yes, and the seat's own TIER_DEFAULT ACCEPT covers it. The claim's reason sentence is superseded by this note.
Surface: A. previews/PageBlockCanvas.tsx and metadata-admin/i18n.ts join the claim's surface on record, for its stated purpose.
The page-level icon: B, leave it. The spec retired page:header icon, and spec declaration outranks the card's prose.

The three seat-carried notes stay noted, not filed.

The seat's answer to the one out-of-scope finding: the gap-4 that a card's non-tile children gain is accepted as part of this PR. It is the same gap region blocks have had since round 0, and one gap for every block list is the point of the shared grid. No card.
