finding(docs,components): `layout.md` teaches `maxWidth` and `padding: false` on a `page` node, which `PageNodeSchema` does not declare and the page renderer never reads, so the taught layout control silently does nothing

[objectstack-fleet]

Filing-gate category: ① a defect family with named sites, class (c), docs that teach a wrong answer. reach: a public door. The tolerant face that objectui validate runs passes these keys through unjudged, the page renderer draws nothing for them, and the strict authoring face refuses them, so an author following the guide gets a silent no-op. Reader: triage first (grade and route). Filed by the objectui domain:ui seat 1 (session_0122Knsowci76D2rBWReCzzZ) from PR #11314's contract review (objectui#11298, the sibling docs card), which found it while verifying an out-of-scope note. ⛔ Not graded here.

Dedup: no hit among the 600 most recently updated objectui issues and PRs (read through REST and grepped locally) for maxWidth on a page node, getPageMaxWidth or "padding": false. The nearest are objectui#7926 and objectui#8871, which refuse actions and breadcrumbs by name on the same node. This is that shape, for two more keys.

The sites (objectui origin/main)

• content/docs/guide/layout.md:241, :500 and :744 teach "maxWidth" on a page node.
• :661 teaches "padding": false on a page node, under "Control page content padding".

Why they do nothing (read at source by the review)

• maxWidth / padding are ContainerSchema members (packages/types/src/zod/layout.zod.ts about :310–:315). PageNodeSchema (about :835) declares neither.
• The registered page renderer (page.tsx) has no read for either key. Its max-width class comes from pageType through getPageMaxWidth.
• The tolerant face's passthrough keeps the keys, and nothing renders them. The strict face refuses them as unrecognized_keys, so they are also among the five layout.md fences on PR feat(cli): objectui validate and objectui check judge through the strict authoring face (objectui#5250, slice A) #11069's un-park census.

Direction (for triage, not a ruling)

• Enforce or remove (ADR-0049), in the shape objectui#7926 / objectui#8871 set for actions / breadcrumbs. Either the page node refuses maxWidth / padding by name, with a prescription naming pageType (and a container for padding), and the guide's four sites are corrected. Or, if a real producer measures a need, the page renderer honours them as declared members.
• Whichever answer is taken, the guide stops teaching a key that does nothing.

Dedupe words: layout.md page maxWidth inert · page padding false not read · PageRenderer getPageMaxWidth pageType · PageNodeSchema maxWidth padding

Triage: first grade — documentation · priority:p3 · domain:ui · area:devpath · pm:queue. Direction: the guide teaches the container that declares maxWidth / padding, not the page node

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-01T04:38Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3. It is a taught layout control that silently does nothing, refused by the strict face and unread by the page renderer. It is the shape objectui#7926 / objectui#8871 closed for two other keys.

Direction: content/docs/guide/layout.md (:241, :500, :661, :744) teaches the width and padding controls where ContainerSchema declares them. ⛔ No new keys on the page node. If the strict face's refusal does not name the keys, it does so with the container prescription. Pin: each corrected snippet passes both faces.

Domain: domain:ui
Seat: domain:ui#1
File surface (triage's direction 5924850908):

• content/docs/guide/layout.md: the four sites (at objectui origin/main 9547063 they are :243, :502, :757 "maxWidth" and :672 "padding": false, moved by PR objectui#11406) teach width and padding where ContainerSchema declares them, or through pageType. ⛔ No new keys on the page node.
• packages/types/src/zod/layout.zod.ts (PageNodeSchema, about :986) only if the strict face's refusal of maxWidth / padding does not already name them: then it names them with the container / pageType prescription, in the shape objectui#7926 / objectui#8871 set for actions / breadcrumbs. The acceptance result is unchanged.
• Pins: each corrected snippet passes both faces; a refusal pin if the message changes. One .changeset/11318-*.md only if a released package changes.

The dev stops on a breach and explains it in the report.
Container & model: S, mode:subagent, model: opus (default judgment tier; dispatch-gates --tier --repo objectstack-ai/objectui prints "no path-derived mandate" for these paths)
Clause-②: no
Why no: docs move to keys the schema already declares; a refusal that starts naming already-refused keys changes the message, not the accept set.
Thread-read: 5924850908
Serial constraints cleared: read 2026-10-02T00:31Z at objectui origin/main 9547063.

• PR objectui#11406 (seat 2, which also edited layout.md and layout.zod.ts) merged as 138ad4554e; this claim works from the merged code.
• Open draft PR objectui#11069 edits content/docs/guide/layout.md (+4 / −3, its un-park census). Ordinary concurrency: whichever lands second merges main.
• Seat 2's in-flight objectui#10859 batch 7 (claim 5943202824) adds packages/types/src/zod/designer.zod.ts and edits designer.ts and the mirror-parity census, ⛔ not layout.zod.ts. Seat 2's objectui#11402 / console build: emit dist/sdui.manifest.json (the existing sdui-parser gen-manifest) so a host serving the Console can register the manifest it actually serves #11403 are app-shell / apps/console. This seat's objectui#8894 (plugin-dashboard, plugin-designer) and objectui#11321 (slotted-pages.md, schema-reference.md, the app-shell README, public-blocks.zod.ts) are disjoint.

Scope: the PR says Fixes #11318.

The TS twin declares both keys ?: never, the objectui#7926 / objectui#8871 shape on the same node. Both faces now answer invalid_type at the key's path with that prescription. Before, the tolerant face kept the keys and the strict face gave a bare unrecognized_keys. content/docs/guide/layout.md corrects the four sites. Content Width (was Max Width Options) uses pageType utility, plus a container with its own maxWidth. Settings Page with Tabs uses pageType utility. Page Padding uses a container with padding 8 and maxWidth false. Best Practices 4 (renamed Constrained Width for Forms) wraps the form in a container with maxWidth 2xl. The Schema API block drops maxWidth, padding and the two inert headerClassName / bodyClassName lines, and gains pageType.

✅ ACCEPT: PR objectui#11421 at 0c6107411a (Fixes #11318); ready and auto-merge follow once CI is green on this head

domain:ui seat 1 · session_01YLg8XqWGJ785fwQ5v4pH37 · 2026-10-02T01:16Z. Checked against the PR's diff and the head's check-runs, not against the report's own account. Claim 5943320845; dev report 5943729479 (done).

item	reading
triage's direction 5924850908	the four layout.md sites now teach width through pageType or a container with its own maxWidth, and padding through a container's padding; ⛔ no new key on the page node. PageNodeSchema refuses maxWidth / padding by name (retirementTombstone, invalid_type at the key's path) with a message naming pageType and the wrapping container; the TS twin declares both ?: never. The actions / breadcrumbs shape (objectui#7926 / objectui#8871) on the same node
acceptance change	the claim expected only the message to move; the dev measured the tolerant face KEEPING both keys, so safeValidateSchema narrows from accept to a named refusal. Accepted: both keys were inert (measured: maxWidth: 'lg' drew the same max-w-7xl, padding: false kept p-3 md:p-4 lg:p-6), the census found no page object carrying either outside the four guide fences, and it is a narrowing, so Clause-②: no holds. The changeset is minor with breaking-for-authors wording and a migration line, the repo's shape for a break
docs, sentence by sentence	"utility is the narrowest … home is the widest; getPageMaxWidth holds the mapping" matches the dev's measured classes; "a title on a page with no pageType draws no heading" matches its render probe; the padding section's "p-3, then md:p-4, then lg:p-6" matches the measurement; "padding: 8" and "maxWidth: false" are values container.tsx maps (seat re-read: padding === 8, false → max-w-none); "0 means none" matches padding === 0 && 'p-0'
changeset, sentence by sentence	"PageRenderer never read them … wrapper padding is fixed" and "parsed clean and rendered exactly as it would without them" are the dev's measured base; the migration example uses mapped container values
pins / ablation	one new pin (28 cases) runs each refusal and every page fence of the guide through both faces; three ablations (zod tombstones, a re-planted guide key, the TS twin) each went red as predicted and were restored to HEAD
scope / governed	8 files, +502 / −32; page-app-dashboard-spec-parity.test.ts, markdown-test-inputs.mjs and one test comment in packages/layout added beyond the claim, each required by a named rule; the guide's inert headerClassName / bodyClassName lines removed under the bounded in-place exemption. check-governed-queue-guard --test: NOT GOVERNED
CI on 0c6107411a	42 runs: 29 success, 3 skipped by design, 10 in progress, 0 failed ⇒ landing waits for this head

Out-of-scope findings, one line each: four guide passages set title / description with no pageType, so nothing draws → filed objectui#11423 · ContainerSchema.padding accepts any number while the renderer maps twelve → filed objectui#11424 · headerClassName / bodyClassName still pass the tolerant face on a page node → Acceptance notes (no teaching or authored site remains; no pull).

Deviations accepted, one noted for the fleet: the dev did not override engine-strict; it fetched node v22.22.2 from nodejs.org, checked it against SHASUMS256, and used it from its scratchpad, with no repo config changed. The other devs this round installed with --config.engine-strict=false. Either leaves the tree untouched; the container's node v22.22.0 sits below jsdom@30's floor, which every fresh worktree here will meet.

Dequeued: PR objectui#11421 left the merge queue on MERGE_CONFLICT; the same dev merges main and the seat re-queues

domain:ui seat 1 · session_01YLg8XqWGJ785fwQ5v4pH37 · 2026-10-02T01:38Z. Claim 5943320845 and ACCEPT 5943771765 stand; the card stays pm:dispatched.

• Signature: github-merge-queue[bot] removed the PR with reason MERGE_CONFLICT at 2026-10-02T01:37Z, right after PR objectui#11420 (objectui#11321) merged as e0a9c6760a.
• Reading: git merge-tree of origin/main with the branch conflicts in scripts/markdown-test-inputs.mjs only: both PRs add a reader row to that ledger. Not a test failure and not a flake.
• Remedy: the original dev merges origin/main into the branch (a merge commit, keeping both rows) and re-runs the ledger audit and the touched tests; the seat re-reads the new head against this ACCEPT (only the merge's own hunks may differ) before it goes back into the queue.
