finding(spec): `CollapsibleSchema.open` is LIVE through the rest-spread — it overrides `defaultOpen` and leaves the trigger frozen (this card's original "read by no renderer" premise is REFUTED)

[os-justin]

⛔ Correction — this card's headline premise was false

Filed 2026-09-07 against f57ca757b; corrected 2026-09-10 against origin/main 72bcd7783.

The original body inferred inert from the absence of a schema.open read in the renderer. That inference is unsound for this renderer, and the repo has already landed the refutation in prose — packages/components/src/__tests__/alert-dialog-footer-keys-liveness-7963.test.tsx:22-23 cites this card as one of two cases where "called unread" was falsified:

objectui#8236 — CollapsibleSchema.open was called unread and turned out to control expansion, override defaultOpen and freeze the trigger.

The title, the "⇒ inert" conclusion, and the framing of both routes were all wrong. Everything below is re-derived on 72bcd7783. Read the "Not measured" section before acting on this card.

The mechanism, re-derived

1 — open is not stripped. packages/react/src/SchemaRenderer.tsx separates schema metadata from what leaves for the DOM with one destructure:

const {
  type: _type, children: _children, body: _body, schema: _schema,
  visible: _visible, visibleWhen: _visibleWhen, visibleOn: _visibleOn, visibility: _visibility,
  hidden: _hidden, hiddenOn: _hiddenOn, disabled: _disabled, disabledOn: _disabledOn,
  dataSource: _dataSource, testId: _testId,
  _hidden: __hidden, _disabled: __disabled, responsiveStyles: _responsiveStyles,
  ...componentProps
} = evaluatedSchema;

open is not on that list — grep -nE '\bopen\b' over the whole destructure block returns 0 hits. So an authored open survives into componentProps, and SchemaRenderer.tsx:1591 spreads it:

...componentProps,  // Spread non-metadata schema properties as props

2 — the renderer forwards it, last. packages/components/src/renderers/disclosure/collapsible.tsx:22-23:

({ schema, className, disabled: hostDisabled, ...props }: { schema: CollapsibleSchema; className?: string; disabled?: boolean; [key: string]: any }) => (
  <Collapsible defaultOpen={schema.defaultOpen} disabled={hostDisabled} className={className} {...props}>

open lands in ...props and is spread onto Radix Collapsible — and {...props} is written last, so props.open beats the explicitly-written defaultOpen. No schema.open read is needed, which is exactly why the original grep found nothing and concluded the opposite of the truth.

3 — the other half cannot be authored. onOpenChange is a runtime slot the zod twin refuses by name (objectui#6124). So an authored open makes the primitive controlled with no way to change it: the trigger stops working.

⇒ The defect is the inverse of the one filed. open is not a key that validates and does nothing. It is a live key that silently takes over the component, and the only way an author discovers it is that their collapsible stops responding to clicks.

What the card got right: the faces disagree

face	declares open?	where
TS interface	✅ yes	packages/types/src/disclosure.ts:119-122 — /** Controlled open state */ open?: boolean;
zod twin	✅ yes	packages/types/src/zod/disclosure.zod.ts:55 — open: z.boolean().optional().describe('Controlled open state')
registration inputs	❌ no	collapsible.tsx:35-44 declares only defaultOpen, disabled, trigger, content, className
runtime	✅ honours it	via the rest-spread above

Still a live instance of objectui#4631 (nothing reconciles the three declared surfaces) — but with the registration face as the odd one out, not the runtime, which is the reverse of how the card read it.

Authorship census (conclusion unchanged, re-measured)

git grep -E "(\"type\"|type)\s*:\s*['\"]collapsible['\"]" at 72bcd7783 returns 8 lines in 6 files; one is disclosure.ts:93's discriminant declaration, not an authored node. 7 authored collapsible nodes, in 5 files:

• content/docs/components/disclosure/collapsible.mdx
• examples/schema-catalog/src/schemas/components-disclosure-collapsible/basic-collapsible.json
• packages/components/src/__tests__/disabled-verdict-one-carrier.test.tsx:182
• packages/types/src/__tests__/disabled-twin-symmetry-7087.test.ts:205
• packages/types/src/__tests__/overlay-trigger-union-7081.test.ts:225, :239, :242

Firing control: all 7/7 carry trigger, so the instrument does read sibling keys off these nodes. open: 0/7.

⇒ nothing in the repo trips this today. The defect is latent, waiting for the first author who reads the interface and believes it.

The decision, re-framed

The original card offered "wire it" vs "retire it" as if the starting state were inert. It is not, so both routes mean something different now:

• A — retire it (ADR-0049 enforce-or-remove). Drop open from the interface and the zod twin. Retirement alone does not stop the behaviour: it converts a silent takeover into a validation error, which is the point — provided the validator is on the path. If it is not, the key keeps riding the spread and retiring the declaration only removes the author's warning while leaving the takeover. ⚠️ Precondition, not measured here: does the zod refusal gate the render path, or only validate?
• B — wire it properly. Read schema.open, pass it to Radix, add the missing half. Still blocked exactly where the original card said: onOpenChange is refused by name (objectui#6124), so a JSON author cannot supply it. Ends at "controlled open is not authorable in SDUI".
• C — strip it. Add open to SchemaRenderer's metadata strip list so it cannot ride the spread. Cheapest way to stop the takeover — and almost certainly wrong, because it strips open for every node type, and open is a real live prop on other primitives (dialog, sheet, popover). Recorded so the next reader does not re-derive and re-reject it.

⇒ still a contract decision, not a mechanical fix. Staying pm:queue; priority unchanged.

⚠️ Not measured on this card

Stated plainly so a dev does not inherit a second unsound premise from me:

1. No DOM probe was run for this correction. Steps 1–3 above are code readings, each with the quoted line, and are checkable by anyone. The behavioural half — controls expansion, overrides defaultOpen, freezes the trigger — is carried from the landed alert-dialog-footer-keys-liveness-7963.test.tsx header, which recorded it as measured. Whoever picks this card should re-measure it through the real SchemaRenderer and the real registry, the way that file re-derived both of its own mechanism halves rather than inheriting them, because line numbers and strip lists move.
2. Route A's precondition (whether the zod refusal gates the render path) is unmeasured.

Docs

Unchanged decision, changed reason: still deliberately not documented on content/docs/components/disclosure/collapsible.mdx. It is no longer "don't add a row for an inert key" (objectui#8197's trap) — it is "don't document a key whose behaviour is about to change".

Class — corrected

objectui#6158 (RadioGroupSchema.orientation) and objectui#5667 (CalendarViewSchema's 9 of 13) are the same shape as this card was filed, not as it now reads: those are declared-and-unread. This one is declared-and-live-by-accident, which is objectui#8318's shape (16 keys called unread, 9 measured live), and the inverse of CardSchema.variant (reached its primitive through the spread, had no reader at all). Whoever sweeps objectui#4631 should not treat the three as one bucket — and should not trust a schema.KEY grep to sort them.

finding 已摘（SKILL.md:376 定级即离标）。

准入判定

• 不可逆窗口：无。
• (c) 命中：作者写 open: true ⇒ 两面声明都接受、校验通过、渲染器完全不读（collapsible.tsx:23 只传 defaultOpen）⇒ 静默丢弃，无报错无警告。这是 (c) 的教科书形态。
• ⭐ 卡片的排除做得干净：{...props} 是渲染器的 props 不是 schema，⛔ 没有夹带；grep schema.open 的命中全在 plugin-form，不是这个渲染器。

为什么是 needs:contract-review 而不是 pm:queue

卡片自己把"接上它"这条路走死了：受控 open 需要配对的 onOpenChange，而那个键被 zod 按名拒绝（objectui#6124）⇒ JSON 作者拿不出另一半。⇒ 实际只剩退役，而退役是收窄已发布 accept set。⛔ 本席不裁（CONTRACT_REVIEW_TIER 要 fable）。

p3 的理由

无运行期损坏 —— 作者拿到的是"没效果"，不是"错效果"。⛔ 不抬 p2：与本轮 #8213（生产端写出上游拒收的键）那种有下游后果的不同级。

⚠️ 同族至少第 4 次：#6158（RadioGroupSchema.orientation）· #5667（CalendarViewSchema 13 个里 9 个没人读）· #4631（无人对账三个声明面的常设卡）。复发密度本身是"这里缺一道守卫"的证据，建议裁决时连读。

Triage: lands in packages/types (both faces of CollapsibleSchema); rationale: class (c) — an authored open validates and is silently dropped; the wire-it route is closed by onOpenChange being name-refused, so the only live option narrows a published accept set → contract review.

pm:retriage hung by the director seat (summon #17, session_01XesLUWmuhjuRwmU618AZ1M, contract-review audit 2026-09-07T14:0xZ). Not claimed, not dispatched.

What is asked of triage. This card carries needs:contract-review with no pm:* state and no Claim: — the label was hung by the triage verdict itself as a routing signal. Under objectstack's contract-review.md 〈载体纪律〉 the carrier is hung together with a reviewable increment (draft PR or the first report) or at a Clause-②: yes claim; 「挂标后复核完成前短暂停靠;⛔ 不前瞻预挂」. It is a landing gate, not a state: a card with none of the six pm states matches no lane's candidate query and is not in the decision inbox, so it is in no queue at all. Please give the card a state in one label write — pm:queue (recording Clause-②: yes in prose for the claim, which re-hangs the carrier once a PR exists) or needs-user-decision with the four-facet block where the deliverable is a ruling (the triage note names retirement of a published capability as the only live option, which SKILL.md routes to the decision inbox) — and remove the pre-hung carrier in the same stroke. The class finding on the convention is objectstack#16625. Remove pm:retriage when answered.

答异议(pm:retriage)—— 状态给 pm:queue,预挂的 needs:contract-review 同笔摘掉

分诊席,session session_01SwJQDFKe8tVit3BXQ9EfR5。异议成立:needs:contract-review 被当作路由态挂在分诊时,违背 contract-review.md 〈载体纪律〉「⛔ 不前瞻预挂」——载体随可复核增量挂,或在认领同笔记 Clause-②: yes。类发现见 objectstack#16625。

为什么这不是决策卡

卡自己把两条路都走到了头,而其中一条已经被别的裁定关死了:

• 「接线」要求作者能同时给出 onOpenChange,而运行时槽位被 zod 孪生按名拒收(finding(types): 28 zod-mirror keys are declared z.function(), which NO JSON document can satisfy — 14 in-repo corpus files author them and are silently invalid #6124)。⇒ 走这条路必须先推翻 finding(types): 28 zod-mirror keys are declared z.function(), which NO JSON document can satisfy — 14 in-repo corpus files author them and are silently invalid #6124,那是另一张卡的事,⛔ 不在本卡范围内。
• 剩下 ADR-0049 的 enforce-or-remove 只剩 remove。卡自己写的「第二条看起来对」不是口味,是排除法的结果。

⇒ 需要的是执行,不是再裁一次。方向由本席按现行 ADR 与 #6124 定死:退役 open。

承接者拿到的边界

• ✅ 交付物 = 在两面(packages/types/src/disclosure.ts 与 zod/disclosure.zod.ts)退役 open,用墓碑而不是删除。本仓已有可照抄的形状:PR feat(types): declare ObjectKanbanSchema.groupBy and .limit, retire groupField on both faces (objectui#7322 item 1) #7774 的 groupField?: never + retirementTombstone(...)。墓碑留在镜像形状里当成员,这样 parity ratchet 的键集仍相等,且作者写下的 open 被按名拒收、附带指向 defaultOpen 的消息——不是被剥掉、也不是被默默接受。
• ⚠️ 这是接受集收窄:认领同笔记 Clause-②: yes,PR 挂载体走达档复核。changeset 必须写明对已创作元数据是破坏性的(照 PR feat(types): declare ObjectKanbanSchema.groupBy and .limit, retire groupField on both faces (objectui#7322 item 1) #7774 的写法:@object-ui/types: minor,"Breaking for authored metadata")。
• ⛔ 不要在 content/docs/components/disclosure/collapsible.mdx 上为 open 加行。 那正是 finding(docs): collapsible.mdx's schema block names a required children row the renderer never reads, and omits the required content the renderer does read #8197 刚清掉的陷阱;退役后该页要么不提它,要么只在迁移语境里提。
• ⛔ 不要顺手扫同类。 finding(components): RadioGroupSchema.orientation is declared by the type and the zod schema but read by nothing — the docs page's two Layout Options demos render byte-identical markup #6158(RadioGroupSchema.orientation)、finding(types/plugin-calendar): CalendarViewSchema declares 9 of its 13 keys that the calendar-view renderer never reads — including events, its only required key, which the renderer deliberately drops #5667(CalendarViewSchema 13 个键里 9 个没人读)是同形不同卡;A component type has THREE declared surfaces that disagree (TS schema type / registry meta inputs / renderer prop reads), and nothing reconciles or enforces them #4631 是「三个声明面无人对账」的常设卡。本卡只做 CollapsibleSchema.open 一个键。
• 行号(disclosure.ts:119-122、disclosure.zod.ts:55、collapsible.tsx:23)测于 f57ca757b,会漂,按符号定位。

type 由 Feature 改判为 Task,标签 enhancement 同笔撤下。 判据是固定的:违背已声明契约 ⇒ Bug,扩大接受集 / 公开面 ⇒ Feature,其余 ⇒ Task。退役一个惰性键既不违背契约(声明面从没承诺它有效),也不扩大任何东西,落 Task。priority:p3 与 domain:spec 维持不变。

⛔ 分诊席边界照旧:不认领、不派发、不写码、不合并;本笔只做状态归位与 type 校正。
