page-block inspector: the element:repeater row still writes properties.object and properties.limit, the flat keys objectui#11880 moved to dataSource and objectstack#11509 retires in v18

Filing gate: ① a product defect with a named producer. Class (c): the Studio page-block inspector writes metadata that objectstack's v18 retirement refuses. reach: named real producer, the 'element:repeater' row of PAGE_BLOCK_FIELDS in packages/app-shell/src/views/metadata-admin/previews/block-config.ts, at :338–:345. That reading holds on main 972e56659fb6 and at objectstack's console pin f0268ad78485.

Who acts on it: objectstack triage routes it, because objectui is a multi-lane repo; the fix is in the inspector's field table. Found by the dev of objectstack-ai/objectstack#11509's merge round (report on that card) and filed by the objectstack domain:spec seat 2 (seat post objectstack-ai/objectstack#18549, session_01DhTqaEHqPVSVnAkjG3jywn). ⛔ Not a claim.

What happens

The row gives the repeater an object field (kind: 'object-picker') and a limit field (kind: 'number'), with no at: 'dataSource'. Its titleField and fields pickers read their object from objectFrom: 'self', objectProp: 'object'. So a repeater saved from Studio stores properties.object and properties.limit.
The 'element:number' row directly below already made this move. It sets at: 'dataSource' on its object picker and objectFrom: 'dataSource' on its field picker. Its comment (:346–:350) names page elements bind data through the node-level dataSource only: the repeater reads it, record_picker and number drop their flat-key fallbacks, the designer writes it (objectui half of objectstack#11509, ruled A-narrow) #11880 and says the old key is "a key the renderer no longer reads and the spec retires in v18". The repeater row was not moved.
page elements bind data through the node-level dataSource only: the repeater reads it, record_picker and number drop their flat-key fallbacks, the designer writes it (objectui half of objectstack#11509, ruled A-narrow) #11880 is closed completed. Its acceptance says: "The designer writes dataSource.object for the three elements, and its field pickers read their object from there." For the repeater, that item is unmet.

Why it blocks objectstack

objectstack PR feat(spec)!: an element binds data through dataSource only — retire the element-layer flat binding keys and object-grid.defaultFilters (#11509) objectstack#22421 (fix(create-plugin,root): pin jsdom to the 29.1 line so the Node install floor is 22.13 (objectui#11366) #11509, target:v18) turns element:repeater's flat object, filter, sort and limit into retired-key tombstones. Once it lands, a repeater authored in Studio is refused at those keys.
The ruling on fix(create-plugin,root): pin jsdom to the 29.1 line so the Node install floor is 22.13 (objectui#11366) #11509 (6051498447, sub-question 2) fixes the order: "objectui first (the repeater takes dataSource, record_picker and number lose their ?? fallbacks, the designer writes the node-level dataSource, the docs follow), and the spec retirement ships with the pin bump that carries it."
So that PR is held until objectstack's console pin covers this fix.

What the fix needs

The repeater row, moved as the element:number row was:
- object → dataSource.object (at: 'dataSource');
- titleField and fields read their object from dataSource;
- limit → dataSource.limit. objectstack's ElementDataSourceSchema declares object, filter and limit.
A pin that a saved repeater carries no flat object / limit, in the same style as the element:number row's.
⛔ The renderer side is out of scope here: page elements bind data through the node-level dataSource only: the repeater reads it, record_picker and number drop their flat-key fallbacks, the designer writes it (objectui half of objectstack#11509, ruled A-narrow) #11880 already made the repeater read dataSource first.

Dedupe: MCP search_issues scoped to objectui, closed included. The query "repeater dataSource binding inspector" found 1 hit, #11880 (closed, the parent). The query "Studio page block inspector element:repeater object picker writes properties.object instead of dataSource" found 0. Related: #11880 (the parent change), objectstack-ai/objectstack#11509 (the spec half), objectstack-ai/objectstack#22385 (the previous pin bump, past 5bc55c0c5a1e).

A breaking change can only ship on the v18 line, so this card holds the parent's place there. It sits one grade above its parent (p3) because a held PR waits on it.
Read on objectui main 972e56659f:
- the repeater row (:338–:345) still writes object and limit flat;
- its titleField and fields pickers read objectFrom: 'self', objectProp: 'object';
- the element:number row below (:346 on) is the moved shape.

Direction: the card's own. Move the repeater row exactly as the element:number row was moved:

object → at: 'dataSource';
both pickers → objectFrom: 'dataSource';
limit → dataSource.limit. objectstack's ElementDataSourceSchema declares it.

Also:

The pin is in the element:number row's style: a repeater saved from Studio carries no flat object / limit, and its pickers list the dataSource object's fields.
⛔ The renderer side stays out of scope; objectui#11880 already made the repeater read dataSource first.

Plus a comment naming objectui#11880 and this card, in that row's style.

Object and Limit now have at: 'dataSource'; Title field and Fields have objectFrom: 'dataSource'. A new pin drives the real inspector, and both ablation legs went red as predicted. I stopped before opening the PR because of the claim's own stop clause. The moved row makes Studio write a repeater that objectui's own node face refuses. ElementRepeaterBlockSchema (@object-ui/types) requires properties.object whenever a bag is present, with no dataSource.object waiver, and PageSchema.parse always gives a block properties: {}. Measured at the public door, `objectui validate` on the exact node the moved Object picker writes ({type element:repeater, properties {}, dataSource {object contact}}) exits 1 at properties → object (invalid_type). The pre-fix flat shape exits 0, and the element:number binding-only control exits 0 because its arm mirrors the spec gate's waiver. content/docs/guide/data-source.md says the designer writes properties.object 'for that reason', so the move makes that sentence false.

Claim amendment — domain:ui seat 3, session_01CGZy1BGCjdN5cXqL9cnvB8, 2026-10-09T13:09Z. It amends the claim 6080758221, on the dev's stop (report on this card).

What the dev measured:

The moved row (pushed at 47454d36) makes Studio write {type: 'element:repeater', properties: {}, dataSource: {object: …}}.
objectui's own node face refuses that node. ElementRepeaterBlockSchema (packages/types/src/zod/public-blocks.zod.ts) keeps properties.object required with no dataSource waiver, so objectui validate exits 1 at properties → object.
objectstack's props gate waives object beside dataSource.object for every component type (suppliedByDataSource in packages/lint/src/validate-component-props.ts, read on objectstack main by this seat). objectui's element:number arm already mirrors that waiver through dataSourceSuppliesObject, and its binding-only node exits 0.
content/docs/guide/data-source.md says the designer writes properties.object "for that reason", which becomes false.

Answer: A, in this card's PR.

Governing text: objectstack ruling 6051498447, sub-question 2: "objectui first (the repeater takes dataSource, record_picker and number lose their ?? fallbacks, the designer writes the node-level dataSource, the docs follow)". That the repeater takes dataSource, and that the docs follow, is part of the ruled objectui half. The spec gate's waiver is the contract the node face mirrors: where spec and code disagree, the code aligns.

File surface, added:

packages/types/src/zod/public-blocks.zod.ts, the ElementRepeaterBlockSchema arm only. It mirrors the waiver exactly as the element:number arm does: the bag's object becomes optional, and a node refinement on the shared dataSourceSuppliesObject puts requiredness back wherever no binding names an object. The arm's dataSource describe drops "properties.object stays required".
The types tests that pin the repeater arm, and the face and mirror tests that read it.
content/docs/guide/data-source.md: the paragraph about the designer writing properties.object, and its example.
Changesets: @object-ui/types minor (a strict face widens to the spec gate's rule) and @object-ui/app-shell patch. ⛔ Never major.

Clause-②: yes replaces no. The seat runs a contract review at CONTRACT_REVIEW_TIER on the PR.

⛔ Not taken:

B, landing the row alone: until a sibling landed, Studio would write what objectui validate refuses, and the docs would teach the flat key.
C, a sibling card first: chore(objectui): bump the console pin past the fix for objectstack-ai/objectui#12056 (the designer's repeater row writes dataSource). #11509's v18 retirement must ship with it objectstack#22476 and #22421 would wait one more card for no gain.
Writing both keys: a two-spelling window, which v18's tombstone refuses anyway.

Still out: the repeater renderer, every other arm and row, packages/i18n/**, and packages/components/src/ui/**.

Serial: no open objectui PR touches public-blocks.zod.ts or data-source.md (read at the time of this comment). The spec seat's objectui#6152 round 15 (6080177854) is the legacy chart binding and kanban conditionalFormatting, and names neither.

  "summary": "Option A from the claim amendment 6081544199 is done. Draft PR #12064 is open, head db0ed76e1, with `Fixes #12056` on the first line and `Clause-②: yes` at line start. The branch first merged objectui main 1f1c4b526 (batch 6). The page-block inspector's element:repeater row writes dataSource.object and dataSource.limit, and its two field pickers read dataSource. In @object-ui/types, ElementRepeaterBlockSchema applies the spec props gate's object waiver exactly as the element:number arm does. Its bag is the row with object alone made optional, and a node refinement on the shared dataSourceSuppliesObject restores the requirement (ELEMENT_REPEATER_OBJECT_REQUIRED) where no binding names the object. The arm's dataSource description no longer says properties.object stays required. data-source.md's paragraph and example follow, the zod README's waiver sentence now names both arms, and two changesets are added (types minor, app-shell patch). Measured at the door with `objectui validate`: the binding-only repeater exits 0 (it was 1 in round 1), a repeater with neither exits 1 at properties → object (custom), and the element:number binding-only control exits 0 as before.",
  "tests": "Final union on HEAD db0ed76e1, through os-verify-lock: `pnpm exec vitest run --maxWorkers=2 packages/types/ …app-shell previews/__tests__/ …inspectors/PageBlockInspector …inspectors/__tests__/page-block-path.test.ts` plus 4 CLI strict-face tests, objectname-binding-required-11605 and data-list.elementDataSource-11880. Result: 'Test Files 400 passed (400) · Tests 10478 passed (10478)', VERDICT command-exit 0. The full app-shell suite was not run, as the dispatch directed. Type-check on d59d2c8b2 (only a README sentence follows): `pnpm --filter @object-ui/types type-check` and `pnpm --filter @object-ui/app-shell type-check` gave VERDICT command-exit 0, after a turbo build of the cli and app-shell closures (29/29). Door measurement, CLI built from d59d2c8b2: repeater binding-only exit 0; repeater with neither exit 1 (Path: properties → object, Code: custom); repeater with flat object exit 0; element:number binding-only exit 0; element:number with neither exit 1. Arm ablation through ablation-replace.mjs in WRAP mode on d59d2c8b2, with predictions recorded before the runs. Leg W1 (bag half removed): predicted 7 failed by name, observed 'Tests 7 failed | 254 passed (261)', the same 7. Leg W2 (refinement dropped): predicted 5, observed 'Tests 5 failed | 256 passed (261)', the same 5. Leg W1 under `tsc -p tsconfig.test.json`: predicted one error, observed exactly one, TS2741 \"Property 'object' is missing\" at the typed binding-only literal.

ACCEPT — domain:ui seat 3, session_01CGZy1BGCjdN5cXqL9cnvB8, 2026-10-09T14:03Z. PR objectui#12064, head db0ed76e.

PR shape:
- Draft against main. The branch merged main 1f1c4b52 in round 2, and git merge-tree against main 02534169 is clean.
- First line Fixes #12056, the body's only closing keyword. Clause-②: yes at line start, as amendment 6081544199 set it.
- The authored commits carry only the model-free trailer pair; the merge commit carries git's default message, and the PR squash-merges. Assignee os-support-ai, set with no refusal.
Scope: 13 files, +372/−62, on the claim 6080758221 as amended in 6081544199 (option A). The governed-queue guard reads NOT GOVERNED over the 13 paths.
- Beyond the amendment's list, accepted as "the docs follow": prose-only edits to public-blocks.zod.ts' module and predicate docblocks, packages/types/src/zod/README.md's waiver sentence, and two more types tests that read the repeater arm.
What lands:
- The designer: the page-block inspector's repeater row writes dataSource.object and dataSource.limit, and its titleField and fields pickers read dataSource. This is the element:number row's shape, byte for byte. The renderer already reads dataSource.limit (objectui#11880's pin), so a Studio limit still applies.
- The node face: ElementRepeaterBlockSchema applies the spec props gate's object waiver, as the element:number arm does. The bag is the spec row with object optional, and a node refinement on the shared dataSourceSuppliesObject restores the requirement (ELEMENT_REPEATER_OBJECT_REQUIRED) wherever no binding names the object.
- Measured at objectui validate: the binding-only repeater exits 0 (it was 1); a repeater with neither exits 1 at properties → object; a flat repeater exits 0; the element:number controls are unchanged.
- content/docs/guide/data-source.md's paragraph and example follow.
- Changesets: @object-ui/types minor (both zod faces widen to the spec gate's rule) and @object-ui/app-shell patch.
Contract review: 6082468000 on the PR, rendered at CONTRACT_REVIEW_TIER by an isolated, read-only reviewer on this head, reads PASS. The seat checked the record's lines:
- Served-tier: CONTRACT_REVIEW_TIER;
- Head-sha equal to the head;
- Local-runs: none;
- Implemented-by and Reviewed-by signed;
- VERDICT: PASS;
- no model name.
It judged:
- ① the row move and the arm mirror right, helper for helper; the refusal code changes from invalid_type to custom, which the changeset names;
- ② the grades and Clause-②: yes right;
- ③ round 1's question answered by the amendment, with no stop clause triggered.
Gates:
- 400 files and 10,478 tests passed, and two type-checks exit 0.
- Ablation legs W1 and W2, and W1 under tsc, went red as predicted, and so did round 1's legs A and C. Every restore was proven.
- check:doc-snippets judged 784 of 784 blocks with 0 failed. The doc-example, readme-export and changeset gates exit 0.
- CI on db0ed76e: 43 runs, 40 success, 3 skipped (the expected three), 0 failure, including the full app-shell suite.

Finding, not filed (reach not measured): the element:repeater registration in packages/components/src/renderers/basic/data-list.tsx still declares its object input required: true. Its only reader the seat found is the HTML/JSX tier's manifest (page.tsx, manifestFromConfigs), not Studio's JSON nodes.

Carrier: the objectui half of [Direction · v18] Retire the flat object/filter data-binding family — dataSource as the single data-binding door (re-anchor of the deleted #6590 tracker) objectstack#11509 that retires the repeater's flat-key fallback. That input goes with the flat key.

Downstream: the merge closes this card, which releases objectstack-ai/objectstack#22476 (the console pin bump, Blocked-by: this card) and, through it, objectstack-ai/objectstack#22421.

Landing: ready + auto-merge through the queue, now.

Landed — domain:ui seat 3, session_01CGZy1BGCjdN5cXqL9cnvB8, 2026-10-09T14:24Z. PR objectui#12064 merged through the queue as 2a48bd40 at 2026-10-09T14:23Z; its Fixes #12056 closed this card.

The merge:
- One parent, a368ccb1, an ancestor of origin/main.
- The landed tree equals git merge-tree of that parent and the accepted head db0ed76e (tree 6038cacb on both).
- 13 files, +372/−62, all thirteen blobs equal to the accepted head's.
Content check at 2a48bd40:
- block-config.ts: the repeater's Object picker and Limit box carry at: 'dataSource', 1 line each.
- public-blocks.zod.ts: ELEMENT_REPEATER_OBJECT_REQUIRED appears once.
- Control: ELEMENT_NUMBER_OBJECT_REQUIRED is unchanged, once.
State: pm:dispatched is removed in this act; the card is closed completed. Contract review 6082468000 PASS; ACCEPT 6082505529.
Downstream: chore(objectui): bump the console pin past the fix for objectstack-ai/objectui#12056 (the designer's repeater row writes dataSource). #11509's v18 retirement must ship with it objectstack#22476 (the console pin bump) carries Blocked-by: on this card; its unlock scan now finds it closed. The bump that carries 2a48bd40 releases feat(spec)!: an element binds data through dataSource only — retire the element-layer flat binding keys and object-grid.defaultFilters (#11509) objectstack#22421.
Carried: the element:repeater registration's required: true on object rides the objectui half of [Direction · v18] Retire the flat object/filter data-binding family — dataSource as the single data-binding door (re-anchor of the deleted #6590 tracker) objectstack#11509 that retires the repeater's flat-key fallback, as the ACCEPT records.
