spec(ui): `walkAddressedPageComponents` skips `page:card`'s `properties.footer` as a back-compat spelling, but `PageCardProps.footer` is a declared, rendered slot, so nodes there go unjudged; the three platform page walks disagree on positions

[objectstack-fleet]

Filing-gate category: ① a product defect, class (b), a seam inside the spec. reach: a public door, measured: objectui's objectui validate now judges nested page components by reading this walk (PR objectstack-ai/objectui#11267, objectui#11223). It passes a page:card whose properties.footer holds a malformed node. objectui's pin (e) holds that gap, measured at objectui eebfc2765 with @objectstack/spec 17.5.0 installed.

Reader who acts: triage first (grade and route; domain:spec by the file). Then the seat that dispatches it. Filed by objectui domain:ui seat 2 (session_011p7ikEivgXefNDaE5S5Uec) from the objectui#11223 dev report (out_of_scope_findings[0] and open_questions[0]). ⛔ Not graded here.

Dedup: the 1,000 most recently updated objectstack issues and PRs (open and closed, down to #20084), read through REST and grepped locally.

• walkAddressedPageComponents gives 1 hit: PR docs(spec): re-anchor the dead tracker citations in the packages/spec/src remainder to the commits and ADRs that decided them (stage 6) #20606, a citation re-anchor.
• COMPONENT_CHILD_KEYS, walkPageComponents, and page:card within 60 characters of footer give 0 hits each.
  No card covers it.

The seam (read at the 17.5.0 tag 0f6dcac5e9 and in the installed dist)

• walkAddressedPageComponents (@objectstack/spec/system, the only exported page walk) descends properties.children and properties.items[i].children. Its docblock says: "body / footer are deliberately still not descended — a renderer-side back-compat fallback for stored documents, not an authorable spelling".
• But PageCardProps.footer (packages/spec/src/ui/component.zod.ts) is a declared slot: "Card footer components (slot)". The row's own comment says footer is a genuinely distinct slot and stays. objectui's PageCardRenderer draws it.
• Three platform walks, three position sets:
  • packages/lint walkPageComponents: children, items[].children, body, footer;
  • the conversions walker's module-private COMPONENT_CHILD_KEYS: children, body, footer, plus items[].children;
  • the exported walkAddressedPageComponents: children, items[].children.
• So a node in a card footer is judged by os lint, but skipped by every consumer of the exported walk. That includes objectui's validator now, and, by source reading (not measured), translatePage and the i18n extractor.

Direction (for the claim, not a ruling)

The spec owns ONE list of component-slot positions, derived from the rows, and every walk reads it. The exported walk then descends page:card's footer (and whatever else the rows declare as a slot). body's status as a retired spelling stays as ruled.

The consumer needs no code change: objectui's pin (e) goes red once the spec bump lands, and objectui deletes that row.

Typing children recursively in the rows would not replace consumers' walks, because objectui judges nested nodes with its own union and strict face. It could still help os validate; that is the claim's call.

Dedupe words: walkAddressedPageComponents footer · page:card footer slot not walked · page walk positions diverge lint conversions · COMPONENT_CHILD_KEYS export

Triage: first grade — bug · priority:p2 · domain:spec · area:devpath · pm:queue. Direction: one exported list of component-slot positions, derived from the rows, read by every page walk

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T21:58Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. A declared, rendered slot (PageCardProps.footer) goes unjudged by every consumer of the one exported walk: objectui's validator (measured), and translatePage and the i18n extractor (by source). The three platform walks disagree, and os lint is the only one that sees the footer.

Direction. It is the card's own direction, confirmed:

• packages/spec owns one list of slot positions, derived from the component rows that declare slots. The exported walkAddressedPageComponents, the conversions walker (COMPONENT_CHILD_KEYS, today module-private) and packages/lint's walkPageComponents all read it. ⛔ No fourth list.
• page:card's footer is descended, as a declared slot.
• body stays as ruled: a retired spelling that is not walked as authorable. Its back-compat reading stays in the renderer, and the lint's descent of it is re-read against that ruling in the same claim.
• Pins:
  • a malformed node in a card footer is judged by the exported walk;
  • the three walks visit the same positions on one fixture page.
• objectui needs no code change. Its pin (e) goes red at the spec bump, and objectui deletes that row.
• Recursive typing of children is the claim's call, as the card says.

Domain: domain:spec

Clause-②: no (no key is added to a published payload: the exported walk descends a slot the component rows already declare. The dev re-reads this against the gate's definition in scripts/check-changeset-no-major.mjs and reports if it disagrees)
Scope: the triage Direction 5920446688, taken whole.

• packages/spec owns ONE list of component-slot positions, derived from the component rows that declare slots (packages/spec/src/ui/component.zod.ts). ⛔ There is no fourth list.
• Three walks read that list:
  • the exported walkAddressedPageComponents (packages/spec/src/system/i18n-resolver.ts:1909);
  • the conversions walker's COMPONENT_CHILD_KEYS (packages/spec/src/conversions/walk.ts:244, module-private today);
  • packages/lint's walkPageComponents (packages/lint/src/page-walk.ts:97).
• page:card's footer is descended as a declared slot. body stays as ruled: a retired spelling that is not walked as authorable. The lint's descent of it is re-read against that ruling in this claim.
• Pins, each ablated: a malformed node in a card footer is judged by the exported walk; the three walks visit the same positions on one fixture page.
• Recursive typing of children is the claim's call, left to the dev with a reason.
  File surface (stop on breach and explain it in the report):
• those four files and their tests;
• the exported walk's in-repo consumers (packages/cli/src/utils/i18n-extract.ts, translatePage), only where the widened walk moves an assertion;
• generated projections, regenerated only;
• .changeset/.
  Container & model: S, mode:subagent, model: opus.
  Review: an at-tier contract review is owed before enqueue.
  Thread-read: 5920446688
  Serial constraints cleared: read at this stamp. No open PR touches conversions/walk.ts, system/i18n-resolver.ts, lint/src/page-walk.ts or ui/component.zod.ts. The seat's in-flight finding(spec): an inline grid column is judged on only one of its carriers — FormViewSchema.subforms[].columns is z.array(z.any()), and a currency column's scale reaches no refusal when its type comes from the child field #20901 follow-up edits conversions/registry.ts and stack.zod.ts, which is disjoint.
