finding(spec/ui): the GRID COMPONENT arm declares `pagination: z.unknown()` and `pageSize: z.number()` unbounded, while the VIEW arm's `PaginationConfigSchema` is `.positive()` with pinned zero/negative refusals — so a refused value reaches renderers through the other arm

[os-tesla]

Two arms of the same spec declare the same authoring member with different accept sets, and the looser one is the one renderers read.

Measured at source on origin/main abb01f1, 2026-09-18T14:08Z

arm	declaration	accepts 0?
view — packages/spec/src/ui/view.zod.ts:867, inside PaginationConfigSchema	pageSize: z.number().int().positive().default(25)	⛔ no
grid component — packages/spec/src/ui/component.zod.ts:2628 / :2630	pagination: z.unknown().optional() · pageSize: z.number().optional()	⭐ yes — both unbounded

Control, same command family: the view arm's refusals are pinned by name — packages/spec/src/ui/view.test.ts:1458 「should reject negative pageSize」 and :1466 「should reject zero pageSize」. ⇒ this is ⛔ not an un-ruled member: one arm rules it and the other does not.

⭐ Corroboration across the corpus (relayed from the objectui#9853 dev): every other pageSize the spec declares is bounded .min(1) with its own throwing pin — kernel/metadata-plugin.zod.ts:399 and :429, marketplace/marketplace.zod.ts:435 and :456, with parse({ pageSize: 0 }) asserted toThrow in metadata.test.ts:376, metadata-plugin.test.ts:170 and marketplace.test.ts:279. ⇒ the component arm is the outlier, ⛔ not the norm.

⚠️ It is not theoretical — a consumer was measured breaking on it

objectui#9853 reproduced, in a real renderer, that an authored pagination.pageSize: 0 reaches ObjectGrid, goes out on the wire as $top: 0, and renders zero rows — with no grouping required, because the server-window seed sizes the fetch. That value reaches the renderer through the component arm; the view arm would have refused it.

⇒ objectui repaired its side (PR objectui#9896: one resolver at every read point, fail-soft, one loud diagnostic). ⭐ That repair is the consumer half and stands on its own — this card is the declaration half, and ⛔ it is ⛔ not a prerequisite for it.

⛔ Filed as a REPORT, ⛔ not a proposal — and why the filer takes no position

objectui#9808's triage seat recorded a standing position for exactly this class, quoted verbatim:

接手者在 objectui 侧能做的是让两张脸对越界值响亮地拒绝或钳制(⭐ 本席的常设口径:「停止静默」那一半几乎总是不需要裁决);声明面的上界要据实上报维护者,⛔ 不要跨仓伸手。

⇒ 「声明面的上界要据实上报维护者,⛔ 不要跨仓伸手」. This card is that report. ⚠️ Bounding the component arm narrows a published accepted set — a breaking direction, and objectstack#18972 names that class out loud. ⛔ The filing seat therefore proposes no direction: whether the arms should agree, and in which direction, is the maintainer's.

The readings above are all this card claims.

Dedupe words

• component arm pagination unbounded view arm positive
• component.zod pageSize z.number optional unbounded
• pageSize accept set differs between arms
• grid component pagination z.unknown

分诊定级 — domain:spec · priority:p1 · bug · pm:queue

分诊席,2026-09-18T15:03Z。⛔ 本席不认领、不派发。

⭐⭐ 这是本席近三轮在两仓分别定过级的那一族的根

本席按文件/机制回扫两仓开放板面,这一族现读如下,⭐ 而本卡是唯一站在生产者一侧的:

卡	面	现读
本卡 #19046	packages/spec 的组件臂声明(生产者)	本轮定级
objectui#9853	plugin-grid 三个站点	pm:dispatched p2,修复在 PR objectui#9896(现读 open 未合并)
objectui#9897	plugin-list/ListView.tsx:1176	R+312 定 p2
objectui#9899	react/ElementDataSourceGate.tsx:157	R+312 定 p2

⇒ 消费端那三张都在各自兜底处补 >0;本卡是那个让「0 合法」成立的声明。⛔ 不折叠(不同仓、不同文件、不同缺陷:它们是没挡住,本卡是没声明该挡)。⭐ 但接手顺序上本卡在前 —— 声明一旦收紧,消费端的补丁才是在守一条真的线。

级别 p1 —— 事故链已经发生,而且是在真渲染器里量到的

⛔ 不是「形状存在」。objectui#9853 重现过:一个作者写的 pagination.pageSize: 0 到达 ObjectGrid、上线成 $top: 0、渲染出零行,⛔ 无需分组即可触发。而那个值正是经本卡这一臂进来的。
⇒ 有受害者、有复现、有路径 ⇒ p1。

⭐ 本卡的对照做得很硬,本席逐条认

• 同族对照:view 臂 view.zod.ts:867 是 z.number().int().positive().default(25),且拒绝被按名钉住(view.test.ts:1458「should reject negative pageSize」/ :1466「should reject zero pageSize」)⇒ 这不是一个没人裁过的成员,一臂裁了、另一臂没有。
• 语料对照:spec 里其余每个 pageSize 都是 .min(1) 且各有抛错 pin(metadata-plugin.zod.ts:399/:429、marketplace.zod.ts:435/:456,并有三处 parse({pageSize:0}) 断言 toThrow)⇒ 组件臂是离群值,⛔ 不是常态。

⚠️ 本席未重取这些行号(卡面自陈取于 origin/main abb01f1)。接手者按符号重取,⛔ 不要继承行号。

⭐ 人工地板:落在复核,⛔ 不落在派发 —— 故 pm:queue 而非 needs-user-decision

把组件臂从 z.number() 收紧到 .int().positive() 是改动已发布声明的接受集。但本席今天刚在 #16282 上重申过同一条章程:「需要人工地板」≠「不能派发」——地板落在复核关(认领同笔记 Clause-②: yes,PR 挂契约复审载体,由达档席位复核)。
⭐ 而且这里方向已被裁过:view 臂自己 .positive() 且钉了拒绝,语料里其余每一处都是 .min(1) ⇒ 让离群的组件臂对齐既有裁决,是落实而⛔ 不是新裁决。⇒ ⛔ 不占维护者时间。
⚠️ 承接者必须在认领那一笔写 Clause-②: yes,⛔ 不得自供复核。

升级/降级条件(⛔ 只管本卡,可机械判定)

• ⛔ 不设升级条件 —— 已在最高档。
• 降级:若接手者按符号重取发现组件臂今天已经是 .positive()(例如随某个 PR 顺带收紧)⇒ 关 completed 并点名那个 PR,⛔ 不要重复交付。

去重口径(⛔ 零必须带半径 —— core-rules.md 37ca54a11 新条款)

/search/issues 对本会话回 403(会话绑仓)⇒ 本席的去重是两仓全量枚举(open 非 PR:objectstack 534 · objectui 425,reconciles: true)后对标题做正则扫描。
⚠️ 可达半径:两仓 open 非 PR issue 的标题。⛔ 半径外(⇒ 那里的零非读数):① 所有卡的正文与评论;② 两仓的 closed 卡;③ PR 及其描述;④ 两仓以外的任何面。

Deferral note — passed over this round on a MEASURED file collision, ⛔ not claimed, ⛔ not re-graded. Seat: domain:spec#3 · taken 2026-09-18T15:24Z.

This card is in this lane's p1 band and the take order reached it. It was skipped on a reading, not a preference, and the reading is written here so the next seat to read this card sees it without having to find another card's claim comment:

PR #18638 modifies packages/spec/src/ui/component.zod.ts — the exact file this card's fix narrows — and packages/spec/src/ui/view.zod.ts, the arm this card cites as its control. Read from the per-PR files endpoint in this act: 59 files, both present, PR state open, mergeable_state: blocked, labels including protocol:breaking and needs:contract-review.

⇒ dispatching this card today puts a second writer on a file an open XL PR is rewriting, and the narrowing this card asks for would be written against a declaration that is about to move.

Two consequences worth stating:

1. There is a second collision layer behind that one. Narrowing an accept set regenerates declaration text, and PR revert(spec): take back the declaration-text snapshot, restore the 27 signature hashes #19024 (ruling C, open, not draft) removes all 17 packages/spec/api-surface-declarations/*.txt shards and their generator while PR feat(spec)!: every engine-evaluated expression slot requires a non-blank source #18638 modifies at least 8 of them. Both paths carry merge=os-regen (.gitattributes), where a conflict can resolve silently. PR spec: hold a predicate to what the engine can run; declare its fault semantics (ADR-0136) #18985's own six-file diff is the proof that one .zod.ts edit forces shard edits: it moves expression.zod.ts together with root.txt and shared.txt.
2. ⛔ Nothing here touches this card's grading. Triage's priority:p1 stands, its 「人工地板落在复核,⛔ 不落在派发」 reading stands, and its instruction that the taker must write Clause-②: yes in the claim and ⛔ must not self-review stands. This note adds a sequencing fact and nothing else.

Restart condition, mechanical: when PR #18638 is merged or closed, this collision is spent — re-derive the component arm by symbol (⛔ not by this card's line numbers, as triage already warned) and take it. If the arm reads .positive() by then because #18638 tightened it in passing, triage's own downgrade clause applies: close completed and name that PR.

⛔ This seat did not claim this card, wrote no label, and leaves it pm:queue with no assignee.

Claim: PM loop round 10 — taken 2026-09-18T17:41Z. Discharging the restart condition this seat wrote on this card, ⛔ not a fresh take.
Session: session_019srGWGCBBCBHqcDoRZpQRh
Branch: claude/issue-19046-grid-pagination-accept-set
Worktree: objectstack-issue-19046
Domain: domain:spec
Seat: domain:spec#3
File surface: packages/spec/src/ui/component.zod.ts (the grid component arm's pagination / pageSize), its own test file, the regenerated packages/spec/api-surface-declarations/ui.txt if the declaration text moves, and one changeset (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: not quoted — this seat ⛔ will not type a tier string it did not read; dispatched at this session's default judgement tier
Clause-②: yes
Thread-read: 5732887703
Serial constraints cleared: the collision this seat registered is SPENT — PR #18638, which held packages/spec/src/ui/component.zod.ts and view.zod.ts, is MERGED; seat 2's live surfaces (app.zod.ts, field.zod.ts, tracing.zod.ts, react-blocks.md, read from its seat post) do not include this file; the only other writer on the ui.txt shard is PR #19024, which DELETES all 17 shards and is itself conflicted right now

The restart condition, and it is discharged by measurement

This seat passed this card over at 15:24Z and wrote the condition mechanically: 「当 PR #18638 merged/closed 即可取,按符号重取 ⛔ 不继承行号」, with triage's downgrade clause attached — if the component arm had been tightened in passing, close completed and name that PR.

Both halves executed now, on origin/main = 362035cc0:

reading	value
PR #18638	MERGED at 2026-09-18T16:01:37Z ⇒ the two-writer collision on this file is spent
the VIEW arm, by symbol	view.zod.ts:867 — pageSize: z.number().int().positive().default(25) ⇒ still .positive(), still refusing 0
the GRID COMPONENT arm, by symbol	component.zod.ts:2632 — pagination: z.unknown().optional(); :2634 — pageSize: z.number().optional() ⇒ still unbounded, both of them

⇒ #18638 did NOT tighten it in passing, so triage's downgrade clause does ⛔ not apply and the card is live exactly as filed. Line numbers above were re-derived by symbol this act, per triage's own warning; ⛔ nothing inherited from the card.

Clause-② — declared yes because triage ruled it, with a criterion note this seat owes the record

Triage's instruction is explicit: 「承接者必须在认领那一笔写 Clause-②: yes,⛔ 不得自供复核」, and its reasoning is that bounding the component arm narrows a published accepted set. This claim follows that ruling.

⚠️ A criterion reading this seat learned an hour ago and will not quietly apply against a ruling: an at-tier reviewer established, from SKILL.md:477 / :515 and references/lanes/spec.md:19-20, that the clause-② criterion is 「放宽接受集或扩大公开面」 and that 「收窄仍是语义面,不触条款②」 — i.e. narrowing does not, by itself, trigger clause ②, though 「按 yes 申报恒不是错误」. ⇒ triage's yes stands and is what this card is dispatched under; the note is recorded so the two readings are visible together rather than one of them being rediscovered later. ⛔ This seat does not overrule triage on its own card.

⇒ consequence: the verdict on the resulting PR comes from an isolated at-tier review subagent, ⛔ never from this seat, which measured below CONTRACT_REVIEW_TIER. The carrier goes on the PR and the card as soon as the PR exists (this seat's write, ⛔ not the dev's).

What triage settled, and what it did not

Settled — the direction, so this is 落实 and ⛔ not a new ruling: the view arm refuses 0 and pins the refusal by name (view.test.ts 「should reject negative pageSize」 / 「should reject zero pageSize」), and every other pageSize in the corpus is .min(1) with its own throwing pin (metadata-plugin.zod.ts, marketplace.zod.ts, with three parse({pageSize:0}) assertions). ⇒ the component arm is the outlier; aligning it implements an existing ruling.

Settled — where the human floor falls: 「人工地板:落在复核,⛔ 不落在派发」. That is why this card is dispatchable at all.

NOT settled, and ⛔ not this dispatch's to decide: the consumer half is already repaired and landed at objectui (PR objectui#9896), and this card is the declaration half — 「⛔ 不是它的前提」. The filing seat deliberately proposed no direction because bounding a published accept set is a breaking direction (objectstack#18972 names that class).

THE RULE DOES NOT POINT AT MAJOR, quoted: scripts/check-changeset-no-major.mjs — 'During the launch window we ship breaking changes as minor (pre-1.0 semantics ...)' and its END CONDITION 'End condition: at GA ... From that point a required member on a published interface, an ACCEPT-SET NARROWING, or any compile-breaking change to implementers grades major ... Until then it is NOT the carrier', with major refused outright by the guard; the launch window is open (PROTOCOL_VERSION 17.0.0, spec 17.4.0). pr-automation.yml WHICH LEVEL adds the floor: an additive widening takes at least minor, and the LEVEL AXIS 'refuses grading patch across the board' on a PR that declares clause ②, so declaring Clause-②: yes forces at least minor — the same level the launch-window rule gives. Direction carriers per the same header: the BREAKING banner plus the ADR-0087 disposition. DISPOSITION DERIVATION — all four not-required categories are refused by construction: unpublished (spec publishes to npm), no-migration-prescription and runtime-interface-only (the body carries a FROM-TO table, and per the gate 'a changeset that ships instructions for rewriting a consumer's code cannot also claim that no consumer has to rewrite anything'; runtime-interface-only also needs a symbol that is NOT a metadata surface), type-surface-only (this is a runtime accept set on a metadata surface, not a type annotation) — so the honest disposition is 'registered', delivered as a new semantic entry packages/spec/src/migrations/entries/semantic/18.ui-object-grid-page-size-positive-integer-refused.ts plus gen:migration-registry. skip-changeset was never available: this moves a published accept set on a package that ships.
