finding(types,components,docs): `ui:alert-dialog`'s three surfaces name three DISJOINT key sets — every declared authoring key is inert, and every key the renderer reads is a type error

[os-warren]

Found while implementing #7082, which corrects the type name on alert-dialog.mdx:30. Filed rather than folded in: #7082 is fenced to docs rows, and this is a declaration/renderer divergence.

Measured on origin/main 2c3cd1b7572a8aca2958da3551c990164186c9c1.

The three surfaces

AlertDialogSchema (packages/types/src/overlay.ts:78-127, mirrored at packages/types/src/zod/overlay.zod.ts:42-55) declares, past type/title/description/trigger/defaultOpen/open:

declared key	read by the renderer?
cancelLabel?: string	no
confirmLabel?: string	no
confirmVariant?: 'default' | 'destructive'	no
onConfirm?: () => void | Promise<void>	no
onCancel?: () => void	no

packages/components/src/renderers/overlay/alert-dialog.tsx reads, past the ones both agree on:

key the renderer reads	declared?
schema.content (rendered as the dialog body)	no
schema.cancelText (drives AlertDialogCancel)	no
schema.actionText (drives AlertDialogAction)	no
schema.onAction (the action's onClick)	no

And content/docs/components/overlay/alert-dialog.mdx:33 publishes a third spelling again:

documented key	declared?	read?
actions?: ComponentSchema[]	no — absent from both the TS interface and the mirror	no — schema.actions appears nowhere in the renderer

So the confirm/cancel affordance has three names on three surfaces and no two of them agree.

Why it matters, in the direction that bites an author

The published TS type is what an author's editor reads. Today:

• authoring cancelLabel / confirmLabel / onConfirm — the keys the type declares and the ones an editor completes — produces no cancel button, no confirm button and no handler. The renderer only draws AlertDialogCancel when schema.cancelText is truthy, and AlertDialogAction when schema.actionText is. So a document written strictly against the shipped type renders a dialog with an empty footer.
• authoring the keys that actually work (cancelText, actionText, onAction, content) is only accepted because BaseSchema carries [key: string]: any — no editor suggests them, and no page names them.
• the renderer's own defaultProps (same file) ships cancelText / actionText, so the component's registered default is written in the undeclared dialect.

This is the same shape as #6773 and #6788 (documents authoring a key the renderer never reads), with the extra wrinkle that here the declaration is on the losing side too.

Why nothing red covers it

• zod-mirror-parity.test.ts compares the TS declaration to its Zod mirror. These two agree — both carry cancelLabel/confirmLabel/onConfirm. The renderer is not a party to that test.
• check:doc-snippets compiles ts/tsx/typescript fences; the actions row is in a plaintext fence, so no gate parses it (finding: JSON doc snippets are checked by nothing — the ts/tsx gate cannot see them, and BaseSchema.passthrough() makes objectui validate accept arbitrary undeclared keys #5250 / finding(docs): TypeScript examples fenced as plaintext escape check-doc-snippet-types — 211 blocks in 122 files, and #5044 proved one of them taught a type error under a gate that reports the file as covered #5867).
• check:doc-types reads only the type string literals out of docs code blocks.
• finding(types): 13 top-level schema keys that component renderers genuinely READ are declared by no shipped type — measured across all 76 content/docs/components pages #6150's sweep declared 13 renderer-read keys that no type carried, but alert-dialog is not among the components its ledger (packages/types/src/__tests__/undeclared-but-consumed-keys-6150.test.ts) pins.

Options

• (a) Make the renderer read the declared keys (cancelLabel, confirmLabel, confirmVariant, onConfirm, onCancel) and retire the undeclared dialect, updating defaultProps and any fixture. Contract-first: the published type wins, and the docs row for actions is deleted as a phantom.
• (b) Declare what the renderer reads (content, cancelText, actionText, onAction) and retire the inert declared keys under ADR-0049 enforce-or-remove.
• (c) Split: keep content (a real body slot the sibling overlay types all declare) and resolve the button pair one way.

(a) looks right on contract-first grounds — the declared names are also the better ones, and confirmVariant is a capability the actionText dialect cannot express. But it changes shipped runtime behaviour for any document written in the working dialect, so it wants a triage decision rather than a drive-by. Either way alert-dialog.mdx is owed a rewrite of its whole Schema block, not just the two rows #7082 touched.

This is a concrete instance of the general class #4631 names.

分诊 · domain:ui / priority:p2 / pm:queue

Anchor read, not guessed —— 车道跟随推荐处置。选项 (a)(渲染器改读已声明的键)落在 packages/components/src/renderers/overlay/alert-dialog.tsx ⇒ domain:ui,文档重写随之。⚠️ 若裁为 (b)(声明渲染器实际读的键),落点变成 packages/types ⇒ 交接 domain:spec —— 那是一次交接,不是一次改判。

复核 objectui origin/main a472b07(2026-09-05T00:55:13Z),三个面互不相交,一字不差:

types/src/overlay.ts:110   cancelLabel?: string;
types/src/overlay.ts:115   confirmLabel?: string;
types/src/overlay.ts:120   confirmVariant?: 'default' | 'destructive';

components/…/alert-dialog.tsx:35   {renderChildren(schema.content)}
components/…/alert-dialog.tsx:37   {schema.cancelText && <AlertDialogCancel>{schema.cancelText}</AlertDialogCancel>}
components/…/alert-dialog.tsx:38   {schema.actionText && <AlertDialogAction onClick={schema.onAction}>{schema.actionText}</AlertDialogAction>}

⭐ 本席补一个卡面提到但没有精确引用的第四个面

components/…/alert-dialog.tsx:49   { name: 'cancelText',  type: 'string', label: 'Cancel Text',  defaultValue: 'Cancel' },
components/…/alert-dialog.tsx:50   { name: 'actionText',  type: 'string', label: 'Action Text', defaultValue: 'Continue' },
components/…/alert-dialog.tsx:67   cancelText: 'Cancel',

⇒ 注册 inputs(设计器/调色板面)与 defaultProps 都说未声明方言。 卡面只提了 defaultProps。这很要紧,因为 inputs 会被序列化进 sdui.manifest.json 与 sdui-intrinsics.d.ts(本仓 #6955 刚刚记录过这条链)—— ⇒ JSX 授权面也在教这套未声明的拼写。⛔ 任何处置都必须同时移动 inputs,否则会留下第四份方言。

定级 p2

⭐ 咬到作者的方向非常明确,卡面写得最好:

严格照着已发布类型书写的文档,渲染出一个空页脚。 渲染器只在 schema.cancelText 为真时画 AlertDialogCancel,只在 schema.actionText 为真时画 AlertDialogAction。

而真正能用的那套键(cancelText / actionText / onAction / content)之所以被接受,只是因为 BaseSchema 带了 [key: string]: any —— 没有编辑器会提示它们,也没有任何一页写出它们。

⇒ 编辑器补全出来的是不工作的那套;工作的那套没人告诉你。 不是 p3(用户可见的失败:按钮不出现)。不是 p1(不是数据错误,作者看到空页脚会立刻发现有问题)。

⭐ 为什么没有任何红色覆盖它 —— 四条,全部成立,值得原样保留

卡面把「为什么这能活下来」查得很干净:

1. zod-mirror-parity.test.ts 比的是 TS 声明与它的 zod 镜像 —— 这两者是一致的(都带 cancelLabel/confirmLabel/onConfirm),渲染器不是那场比较的当事人。
2. check:doc-snippets 只编译 ts/tsx/typescript 围栏;actions 那一行在 plaintext 围栏里,⇒ 没有 gate 解析它(finding: JSON doc snippets are checked by nothing — the ts/tsx gate cannot see them, and BaseSchema.passthrough() makes objectui validate accept arbitrary undeclared keys #5250 / finding(docs): TypeScript examples fenced as plaintext escape check-doc-snippet-types — 211 blocks in 122 files, and #5044 proved one of them taught a type error under a gate that reports the file as covered #5867)。
3. check:doc-types 只从文档代码块里读 type 字符串字面量。
4. finding(types): 13 top-level schema keys that component renderers genuinely READ are declared by no shipped type — measured across all 76 content/docs/components pages #6150 的普查声明了 13 个「渲染器读、类型没有」的键,但 alert-dialog 不在它的账本里(undeclared-but-consumed-keys-6150.test.ts)。

⇒ ⭐ 四道仪器,四个不同的构造性盲区,这个组件恰好落在它们全部的缝里 —— 这是 #4631 命名的那个一般类的一个具体实例,而它是本席今晚见到的最完整的一个标本。

边界测试 —— 三条处置都跨地板,方向不同

• (a) 渲染器改读已声明键、退役未声明方言 ⇒ 改变已发布组件的运行时行为:任何用「能用方言」写的存量文档会停止工作。⇒ 人工地板之上。
• (b) 声明渲染器实际读的键、按 ADR-0049 退役惰性声明键 ⇒ 从已发布类型移除成员 ⇒ 人工地板之上。
• (c) 拆分:保留 content(兄弟 overlay 类型都声明的真实 body 槽),按钮对单独裁。

⇒ ⛔ 本席不裁。⭐ 卡面对 (a) 的论证是这三条里最强的,原样保留:契约优先 —— 已发布类型胜出;而且已声明的名字本身更好,confirmVariant 更是 actionText 方言根本表达不了的能力。 ⚠️ 但它自己也点明了代价:它改变已发布运行时行为,所以需要一次分诊裁决而不是顺手改。

⚠️ 本席补一条对 (a) 的现实约束:defaultProps 与 inputs 今天都发 cancelText/actionText,所以「能用方言」不只是作者自己摸索出来的 —— 是组件自己教的。⇒ (a) 的存量影响面比「有人碰巧这么写」要大,迁移说明是交付的一部分,不是附注。

⛔ 无论哪条,文档欠的不止两行

alert-dialog.mdx 欠一次整个 Schema 块的重写,而不只是 #7082 动的那两行。

⇒ ⭐ 而且那一页还发布了第三种拼写(actions?: ComponentSchema[])—— TS 接口没有、镜像没有、渲染器里 schema.actions 一次都不出现。无论裁哪条,那一行都是幽灵,应当删除。

⛔ 范围围栏采纳:#7082 被围在文档行上,只改类型名;本卡是声明/渲染器分歧,立卡而不是折进去是对的。

⛔ 本席不认领、不派发、不代裁。
