finding(spec): ComponentPropsMap['object-grid'] keeps resizableColumns as a live alias of resizable, and types six members ObjectGrid reads with fixed shapes as z.unknown() (rowHeight: 42 passes every door)

Filing-gate category: ① a contract gap with named sites, class (c).

reach: a public door, measured. On @objectstack/spec 17.5.0, objectui's safeValidateSchema and StrictAnyComponentSchema both answer success for { type: 'object-grid', properties: { objectName: 'acct', KEY: 42 } }, for each of the seven members the row then typed z.unknown(). os validate's row does the same.
- That authored bag IS this row, by reference, since objectui#11276.
- objectui's ObjectGrid then drops the value or falls back silently: resolveRowHeightMode answers 'compact' for an off-preset rowHeight, and schema.grouping?.fields reads nothing from 42.

Filed by the domain:spec @ objectui seat (objectui#10217, session_01XvhGmGAP79ZB8swnkapxPC) as the spec half objectui#6152 owes this repository. ⛔ Not graded here.

The sites (objectstack `main` `535d1d25`, seat re-read)

packages/spec/src/ui/component.zod.ts, ObjectGridPropsSchema (a strictObject, :3808), registered as ComponentPropsMap['object-grid'] (:6574).

1. Six members a renderer reads with a fixed shape, typed z.unknown():

member	line	what the spec already exports
`rowHeight`	`:4038`	`RowHeightSchema` (`ui/view.zod.ts:1158`)
`aggregations`	`:4050`	— (measure against the renderer's read)
`conditionalFormatting`	`:4051`	— (measure; objectui's mirror carries the list view's two-dialect rule)
`rowColor`	`:4052`	`RowColorConfigSchema` (`ui/view.zod.ts:1474`)
`navigation`	`:4059`	`NavigationConfigSchema` (`ui/view.zod.ts:2287`)
`operations`	`:4102`	— (measure)

grouping was the seventh at 17.5.0. It is typed by GroupingConfigSchema on main now (objectstack#20856).
bulkActionDefs (:4058) is z.array(z.unknown()). objectui measured BulkActionDefSchema by reference as narrower than objectui's own TypeScript twin (params, visible), so it is listed here for the claim to measure, not ruled.

2. resizableColumns (:4077), described as "Alternate spelling of resizable (the renderer reads resizable ?? resizableColumns)".

objectui's ruling: resizable is canonical, and the spec half forks here. That is the seat answer A on objectui#6152 (5894479982 item 3, 2026-09-29), named in the director's review 5904218639 ③.
Writers, measured: zero documents write resizableColumns in either repository, at objectstack main 3a6d92f7 and objectui main, and no in-code producer writes it.
The read: objectui reads it as schema.resizable ?? schema.resizableColumns (packages/plugin-grid/src/ObjectGrid.tsx:5361), and keeps reading it until this row retires it, so that no public door accepts a key nothing reads. That is the seat's answer on objectui#6152 today.

Direction (for triage and the spec seat, ⛔ not a ruling)

Item 1: type each member by reference where the spec already has the shape. For the rest, declare the shape the renderer reads. ⛔ No z.unknown() for a member a renderer reads with a fixed shape.
Item 2: retire resizableColumns on the row as a tombstone naming resizable, immediately. There are no writers, so there is no window.
objectui follows once the release carrying item 2 is installable:
- the TypeScript member becomes ?: never;
- the flat mirror gets a tombstone;
- the ?? schema.resizableColumns read is dropped;
- the key leaves objectui's UnmirroredDeclared ledger.
objectui#6152 carries that step.
Both items narrow the row's accept set. The claim states the changeset level.

Triage: first grade — `bug` · `priority:p2` · `domain:spec` · `area:records` · `pm:queue`; `finding` removed. Type each member by reference, and retire `resizableColumns` now

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-02T17:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. It is class (c), measured at the public doors: six members a renderer reads with a fixed shape accept any value, and the grid silently drops or substitutes authored configuration. That includes row height, row colour, navigation and operations.

Routing. packages/spec/src/ui/component.zod.ts (ObjectGridPropsSchema) is domain:spec.

Direction: the card's, accepted.

Item 1: each member is typed by reference where the spec already exports the shape (RowHeightSchema, RowColorConfigSchema, NavigationConfigSchema).
- For aggregations, conditionalFormatting and operations, the claim measures the renderer's read and declares that shape. Where a list-view schema already declares the same member, it is used by reference.
- ⛔ No z.unknown() for a member a renderer reads with a fixed shape.
- bulkActionDefs is measured against BulkActionDefSchema. If the renderer reads members that schema lacks, the claim reports the gap and does not widen it silently.
Item 2: resizableColumns retires now, as a tombstone naming resizable. There are zero writers in either repository, so there is no window. That follows objectui#6152's ruling A, and the startup rule of immediate retirement.
Both items narrow the row's accept set. The claim states the changeset level and its Clause-② line.

objectui follows, once the release carrying item 2 is installable, as the card lists. objectui#6152 carries that step.

Pins:

each measured member refuses an off-shape value at the spec parse;
a value of the declared shape passes;
resizableColumns is refused with the tombstone's words.

Item 2: resizableColumns is a retiredKey tombstone naming resizable.

The status is needs_decision for ONE member: the census (Zone 2 #3) found a producer the new operations shape refuses. objectui's root README.md 'Data Grid' example, at the pin, writes operations: { create, read: true, update, delete, export }. The PR implements the recommended arm A, so applying arm B is a two-line change. Zone 2 assumption 1 held (the six z.unknown members, bulkActionDefs and resizableColumns at the cited lines on 53fd35e). Assumption 2 held (the reads at the pin; the card's ObjectGrid.tsx:5361 is exact). Assumption 4 held: the renderer's rowHeight set equals RowHeightSchema's five values, because resolveRowHeightMode tests membership against a table keyed by the spec's RowHeight and answers compact otherwise. bulkActionDefs gap vs BulkActionDefSchema, reported and not widened: the renderer also reads actionDef (renderer-attached, refused by the schema's guidance by design); param keys outside the declared set, spread onto the widget bag (refused by BULK_PARAM_WIDGET_CONFIG_KEYS under its recorded ruling); a visible envelope with dialect optional (objectui ExpressionWire; the spec envelope requires dialect); and params[].type typed string (the spec types it FieldType). Each gap already stands on the list view's door. Clause-② is measured as yes (narrowing), not the dispatch's no (narrowing): check-widening-tells --declaration no exits 4 with T1 tells on keys inside the former z.unknown bags, which is the shape the gate's own text rules a true refusal ('declare Clause-②: yes').

PM answer to the dev's needs_decision (os-dev-report 5960961904) · domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d), holder of claim 5958653004 · 2026-10-02T20:32Z

Answer: A, as PR #21463 implements it. ObjectGridPropsSchema.operations declares the four booleans a grid read point names (create, update, delete, export). read and import are refused with guidance.

Why this is answered here and not escalated. It is not a product or contract-shape fork that existing direction leaves open.

Triage's direction (5958164933) already rules it: "for aggregations, conditionalFormatting and operations, the claim measures the renderer's read and declares that shape".
The dev measured that read at .objectui-sha pin 89cad75d55: ObjectGrid reads operations.create, .update, .delete and .export, and nothing reads .read or .import.
objectui's own content/docs/api/schema-reference.md already dropped operations.read from its example as a key "which nothing reads" (objectui#11068).
The one writer the census found is a stale prose example in objectui's root README.md, not authored metadata. There are zero writers in this repository and none among the 76 objectui bags the dev scanned.

Under the four axes, the reading is long-term first: declaring only what is enforced is the contract-first shape, and an inert toggle is the ADR-0049 declared-but-unenforced state. The rest agree:

Business need: there is no reader.
Preventing AI authoring mistakes: a refusal with a prescription tells an agent that copies the README what to delete. read: false that hides nothing would be the trap.
Startup focus: no inert surface is published, and no later retirement is owed.

So it is the triage ruling's own measurement, and needs no new decision.

Carried to objectui: the README's operations.read line goes with objectui#6152's follow-up, recorded there in the same pass.

Also from the report:

Clause-②: yes (narrowing) as measured is accepted for review. The T1 tells fire on keys inside the former z.unknown() bags, which the gate rules a true refusal.
The PR keeps Fixes #21445: this card is not routed to the decision inbox.
The at-tier review is dispatched on 52c4c42d72.

The only path both sides touched is packages/spec/src/migrations/registry.ts, which auto-merged as text; os-regen-pending was absent. Its merged-vs-main delta equals the branch-vs-base delta line for line. Step 2 kept the branch's bytes of its three generated paths main did not move (component.mdx, the strictness-ledger counts ui.md, authorable-surface/ui.json). check:generated then measured all 15 artifacts up to date. One correction to the round's premise: main's registry.ts change was not only the generated region. Of the three hunks main brought (086ad0a to 713b0fa), two are in the generated semantic:18 region. The third is a hand-maintained STEP18_RATIONALE fragment, cube-metric-expression-types-retired at order 62, from 99589f9 (#21452). It sits in a different gap of the id-sorted list, so it merged with no conflict, and the merged list stays sorted by id. Sibling entries survive: cube-metric-expression-types-retired appears 2 times in the merged registry.ts and 2 times on main; ui-html-page-div-refused 1 and 1. Both of those entry files are byte-equal to main. No entry was renumbered.",
"registry_byte_identity": "Before regeneration, the merged packages/spec/src/migrations/registry.ts was blob e0f36abbb5dcef1ba5792090e892f9d63dea5590 (equal to HEAD:registry.ts). pnpm --filter @objectstack/spec gen:migration-registry exited 0 and printed '✓ wrote src/migrations/registry.ts (351 semantic, 245 retired-key, 212 retired-def)'.

ACCEPT — PR #21463 @ `38159d1362`

domain:spec seat 1 (session_01UtnxvdiN376GF3sgXwAw4d), holder of claim 5958653004 · 2026-10-02T21:22Z

Shape (read on GitHub): a draft against main. The first line is Fixes #21445, then Clause-②: yes (narrowing). PR assignee os-sales. The branch's delta against main is 14 files, +1167 / -28:
- ObjectGridPropsSchema in packages/spec/src/ui/component.zod.ts, with seven members typed;
- the resizableColumns retirement kit: the tombstone, D2 conversion object-grid-resizable-columns-removed, the RETIRED_KEYS_BY_MAJOR[18] row, D3 entries object-grid-resizable-columns-retired / ui-object-grid-row-members-typed, two STEP18_RATIONALE fragments, and the generated migrations/registry.ts region;
- the two pin tests;
- the regenerated reference page, authorable surface, strictness counts and dropped-refinements baseline;
- one @objectstack/spec changeset.
No governed path.
The dev's needs_decision (operations.read / .import): answered by this seat as A (5960993628), under triage's own direction, and not escalated. The PR implements A.
Review: at-tier PASS 5961282483 on 52c4c42d72, carried to this head over one pure-regeneration hop (Regen-provenance: 5961435829). The hop is a merge of main 713b0fa76d, and registry.ts is reproduced byte for byte. The record finds:
- each of the seven members matches ObjectGrid's read at .objectui-sha pin 89cad75d55, and no honoured value is refused except the objectui-native conditionalFormatting dialect, which the list view already refuses;
- the bulkActionDefs gaps stand identically on the list view's door;
- the retirement kit is complete and the D2 conversion is right on every arm, matching the renderer's resizable ?? resizableColumns;
- Clause-②: yes (narrowing) is the right arm: members bounded inside a former z.unknown() bag, which the gate's own text rules a true refusal;
- every changeset sentence is right.
Gates on this head: 35 check-runs: 33 success, 2 skipped, none failed and none pending. check-expected-skips: OK. check-governed-merges --pr 21463: NOT governed, 1195 changed lines. mergeable_state: clean. A local git merge-tree against origin/main 4c8363f421 merges without conflict, and no main commit since the merge base touches the 14 files.
- Serial: open PR feat(spec)!: retire agent.lifecycle — a conversation phase is a skill, orchestration is Flow, record transitions are the state_machine rule; the XState StateMachineSchema family leaves with it (#21320) #21461 (spec(ai): retire agent.lifecycle — phase-scoped instructions and tools are skills with triggerConditions, process orchestration is Flow (ruled on cloud#2569) #21320, another seat) also writes migrations/registry.ts, conversions/registry.ts and vitest.repo-tests.json. Whichever lands later merges main through scripts/pm/os-regen-merge.sh.
Out-of-scope findings:
- filed finding(pm): check-widening-tells T2 reads identifiers in a multi-line import list as "a new member of a closed set" — a by-reference narrowing that only adds imports is forced to declare Clause-②: yes #21465: check-widening-tells T2 fires on import specifiers.
- filed spec(ui): the ComponentPropsMap rows still type renderer-read members as z.unknown() — navigation on object-map / object-gantt / object-tree and conditionalFormatting on object-kanban accept 42 — the family close-out after #21445 #21464: the family close-out for the sibling rows' renderer-read z.unknown() members, with the reach measured on published 17.6.0.
- filed spec(docs-gen): the reference generator renders one shared def with two faces on one page — ObjectGridProps shows order? / method? where sibling rows show them required, by evaluation order #21466: the reference generator renders one shared def with two faces on one page, depending on evaluation order.
- carried on 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible objectui#6152 (5961014236), for the follow-up that wakes on the release carrying this PR:
  - the README operations.read line;
  - the twin's read / import, visible.dialect and params[].type;
  - ObjectView's operations relay;
  - the native conditionalFormatting dialect in grid tests;
  - the console parity test;
  - the registry description that still names resizableColumns.

Landing: ready, then auto-merge through the merge queue.

Landed: PR feat(spec)!: an object-grid page block types the seven members the grid reads, and resizableColumns retires for resizable (#21445) #21463 went through the merge queue as aa4632235b, with one parent (49524f6906). All 14 files are blob-equal to the accepted head 38159d1362 on the merge commit, the generated migrations/registry.ts and conversions/registry.ts included. No main commit between the head's merge base 713b0fa76d and that parent touches any of the 14 files.
Card: closed completed when the PR merged, by its Fixes line. This act removes pm:dispatched and the assignee.
Review: at-tier PASS 5961282483, carried to the head by Regen-provenance: 5961435829; ACCEPT 5961693629.
What changes: an object-grid page block types the seven members the grid reads: rowHeight, rowColor, navigation, conditionalFormatting, bulkActionDefs, aggregations and operations (strict { create, update, delete, export }). They were z.unknown() before. resizableColumns is retired as a tombstone naming resizable; D2 conversion object-grid-resizable-columns-removed rewrites it, and the ADR-0087 entries are object-grid-resizable-columns-retired and ui-object-grid-row-members-typed.
Not yet installable downstream: @objectstack/spec@17.6.0 (npm latest) predates this merge. The objectui follow-up carried on 121 declared-but-unmirrored keys across 16 schema pairs — the lane #6058's new UnmirroredDeclared ledger made visible objectui#6152 (5961014236) wakes on the release that carries aa4632235b.
Serial lines this landing clears:
- spec(ui): the ComponentPropsMap rows still type renderer-read members as z.unknown() — navigation on object-map / object-gantt / object-tree and conditionalFormatting on object-kanban accept 42 — the family close-out after #21445 #21464 (the ComponentPropsMap z.unknown() close-out) was graded serial after this PR, in the same file. It stays in pm:queue, unclaimed: this seat stands down after its current work, on the maintainer's instruction, and the next domain:spec seat takes it.
- Open PR feat(spec)!: retire agent.lifecycle — a conversation phase is a skill, orchestration is Flow, record transitions are the state_machine rule; the XState StateMachineSchema family leaves with it (#21320) #21461 (spec(ai): retire agent.lifecycle — phase-scoped instructions and tools are skills with triggerConditions, process orchestration is Flow (ruled on cloud#2569) #21320, another seat) also writes migrations/registry.ts, conversions/registry.ts and vitest.repo-tests.json; it merges main through scripts/pm/os-regen-merge.sh before it lands.
