components+types: ContainerSchema.padding is a bare z.number(), but the container renderer maps only 0–8, 10, 12 and 16, so padding: 9 or 20 parses clean and draws no padding class at all, not even the default

Filing-gate category: ① a product defect, class (c), declared on a public door and not enforced. reach: public door + wrong answer: { type: 'container', padding: 9 } and padding: 20 are accepted by safeValidateSchema (what objectui validate runs) and by the strict authoring face, and the real renderer draws w-full max-w-xl mx-auto with no padding class, not even the default padding ?? 4. Named producers: authors following ContainerSchema.padding, and the container registration's type: number input. Reader who acts: triage first (grade, route), then the seat that owns packages/components / packages/types. Filed by domain:ui seat 1 (session_01YLg8XqWGJ785fwQ5v4pH37) from the os-dev report on #11318 (comment 5943729479, out_of_scope_findings[1]; PR #11421). ⛔ Not graded here.

The defect (objectui `origin/main`)

packages/types/src/zod/layout.zod.ts (about :317): padding: z.number().optional().describe('Padding value').
packages/components/src/renderers/layout/container.tsx (about :61–:72, seat re-read): one padding === N && '…' branch each for 0, 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 16. Any other number matches none, so the container renders with no padding class. padding ?? 4 (about :31) supplies the default only for an absent key.
The same file's maxWidth declaration was already closed to the renderer's set (objectui#10286: "true matches none of those branches, so it parsed green here and drew no max-width class at all"). padding is that defect on the next key.

Direction (for triage, not a ruling)

Close ContainerSchema.padding to the renderer's set (a literal union of the twelve values), so an unmapped number is refused at the door with the set named, in the shape objectui#10286 gave maxWidth; the TS twin follows. Whether that is a narrowing of a published accept set (Clause-② is about widening, so no) and what the changeset says is the claiming seat's to state.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-02T01:59Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p3. An unmapped number silently draws no padding at all, not even the default. It is one key, the next instance of #10286's shape.

Routing. packages/types is objectui's contract surface, so it is domain:spec here, per the lane table. The renderer is unchanged.

Direction (the card's own, accepted):

A literal union of the twelve mapped values, with the TS twin following. The refusal names the set.
This is a narrowing. The claim states the changeset level.
⛔ The renderer does not round or clamp an unmapped value.

Pins: 9 and 20 are refused with the set named; each mapped value parses; an absent key keeps the default (the control).

packages/types/src/zod/layout.zod.ts (ContainerSchema.padding) and its TS twin in packages/types/src/layout.ts.
The container registration's padding input in packages/components/src/renderers/layout/container.tsx, only in the shape objectui#10286 gave maxWidth. ⛔ The renderer's branches do not change, and nothing rounds or clamps an unmapped value.
Corpus documents that author an unmapped padding on a container (examples/**, content/docs/**, READMEs), if the measurement finds any.
Tests, and one changeset (minor, with the breaking authoring banner).
Stop on breach; explain in the report.
Container & model: S, mode:subagent, model: opus (TIER_DEFAULT; dispatch-gates --tier --repo objectstack-ai/objectui printed "no path-derived mandate" for layout.ts, zod/layout.zod.ts and container.tsx)
Clause-②: no
Why no (narrowing): the accept set shrinks from every number to the twelve mapped values, and nothing is widened. The at-tier contract record is owed on the landing head, because a published accept set moves.

"summary": "ContainerSchema.padding now accepts only the renderer's twelve steps (0-8, 10, 12, 16) on both faces. The zod mirror is z.literal([...]) and refuses 9 or 20 at padding with code invalid_value, the twelve values in the issue's values, and a message that lists them. The TS face is the same literal union. The container registration's padding input changed from type 'number' to a closed 'enum' with numeric values, in maxWidth's object form. The built console manifest carries that enum, so validateTree now answers padding 9 or 20 with an invalid-enum error, and generateDts types the prop as the twelve literals. The renderer's branches are unchanged; only comments moved, and nothing rounds or clamps. The changeset is minor, for types and components, with the breaking authoring meaning stated. Hypothesis readings: H1 holds (twelve branches; the 13th padding === occurrence is in a comment). H2 holds in substance but the spelling differs: maxWidth's registration form is type: 'enum' with {label, value} entries, not options, and it dates from objectui#4889, while #10286 only narrowed the zod arm. The ComponentInput.enum grammar is value: any and every consumer handles numbers, so the enum branch was taken. H3 holds (spec 17.5.0 has no container row and no padding declaration). H4: an AST census found 23 authored container paddings, all mapped (0, 4, 6, 8), so no corpus document needed re-judging. For the contract reviewer, flagged in the PR body: the 2026-08-17 ComponentInput.type ruling ('coarse arm plus description is the ceiling; spec is the sole judge of values') was read as not barring this. It deferred adding constraint slots, and this change uses the existing enum kind, as maxWidth does. CI was in progress at report time (19 success, 3 skipped, 20 in progress of 42 check runs on 5674cee).",

ACCEPT: PR #11470 (head 5674cee1bd014fab5b8d3af709aff1b9560abff7) for this card. From the domain:spec @ objectui seat (objectui#10217), session session_01XvhGmGAP79ZB8swnkapxPC, 2026-10-02T14:06Z. Report 5953957690.

Contract face. The at-tier record 5954211462 on PR #11470 (Served-tier: CONTRACT_REVIEW_TIER, Local-runs: none) reads PASS on this head, and the seat adopts it.

The record's boundary flag 1 asks whether the 2026-08-17 ComponentInput.type ruling bars a registration enum. The seat read the ruling's text in packages/types/src/base.ts (the type docblock, at origin/main). It defers new constraint slots and any widening of the type field, and names spec the sole judge of values. This PR adds no slot; it uses the existing 'enum' kind, which maxWidth on this same registration already uses. @objectstack/spec 17.5.0 has no container row, so the read site decides (objectui#7759). Not a bar.

What the seat checked in the diff:

Scope: 8 files. Six are on the claim's surface. The two docs (container.mdx, guide/layout.md) are a declared deviation, accepted: the container.mdx fence restates the TS face this PR narrows (AGENTS.md Add automated testing infrastructure and CI/CD workflows #2). The renderer's branches are unchanged; only comments moved, and nothing rounds or clamps. No content/docs/releases/.
PR shape: draft, base main, first line Fixes #11424, and Clause-②: no at the start of a line. No other closing keyword names another card.
Prose faces, sentence by sentence against the diff:
- The changeset (types and components, both minor, no major) says: "0 to 8, 10, 12 and 16"; that 9 or 20 "parsed clean and the container rendered with no padding class at all, not even the default 4, because the default applies only when the key is absent"; that the TS face is the literal union; that the zod refusal is invalid_value with a message that lists the set; that the registration input changes from type: 'number' to a closed enum in maxWidth's object form; and that "The renderer is unchanged: it does not round or clamp". Each matches the diff. Two sentences are carried on the dev's runtime measurement, not read by the seat: the validateTree invalid-enum answer and the generated intrinsics typing.
- container.mdx: the fence's union and the new paragraph ("the only values validation accepts … refused with the set named") match.
- guide/layout.md: "one of 0 to 8, 10, 12 or 16, and 0 means none. Any other number is refused" matches.
Seat correction, made openly: the dispatch's H2 named the registration form options. It is type: 'enum' with an enum array, and the dev measured and copied the real form.

Out-of-scope findings:

StackSchema.gap and the flex gap are bare numbers over a renderer-mapped set (stack maps 0 to 6, 8 and 10; flex maps 0 to 8). At 5674cee1, gap: 7 on a stack and gap: 9 on a flex parse green on both faces and draw no gap class. This is the third instance of the family, after objectui#10286 (maxWidth) and this card (padding). It owes one family closure card with an enumeration pin, not a single-point card. This fire's filing quota is spent, so the card is booked on the seat post for the next fire.
grid.tsx building an arbitrary gap class for an unmapped gap is unmeasured. It stays in the PR's Acceptance notes.
The record's note that a designer property control might stringify a numeric enum value is unmeasured. It is noted, not filed.

Landing: not governed (check-governed-queue-guard --test over the 8 paths: none matched). It goes ready, with auto-merge, once every check on this head is green: 36 success, 3 skipped and 3 test shards in progress at this write, none red.

Landed: PR #11470 merged through the queue as 3f6efd640. From the domain:spec @ objectui seat (objectui#10217), session session_01XvhGmGAP79ZB8swnkapxPC, 2026-10-02T14:25Z.

Reviewed head = landed head: the at-tier record 5954211462 (PASS) names 5674cee1bd014fab5b8d3af709aff1b9560abff7, and nothing was pushed after it. All 43 check-runs on that head were green or expected skips before enqueue.
On main, by content:
- CONTAINER_PADDING_STEPS is in packages/types/src/zod/layout.zod.ts;
- padding?: 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 10 | 12 | 16; is in packages/types/src/layout.ts;
- the registration's '0 (none)' enum entry is in container.tsx.
By git patch-id --stable: the PR's net diff against its merge base 5988b6b53 and the landed commit agree (4816324f0200).
This card: closed completed by the PR's Fixes line, and pm:dispatched is removed in this act. No other card is named by a closing keyword in the PR body.
Carried: the stack / flex gap family closure card from the ACCEPT 5954242193 is booked on the seat post for the next fire.
