form 组件的设计器默认值 `defaultProps: { submitLabel: 'Submit', cancelLabel: 'Cancel' }` 仍是英文字面量（本仓运行期无人读，但会绕过 #3272 的渲染期回落）

[yinlianghui]

在实现 #3272(PR #3392)时发现,未在该 PR 内修改 —— 那一单的 PM 裁定明确划到「组件侧 prop 默认」,设计器元数据是另一个面。

现象

packages/components/src/renderers/form/form.tsx,ComponentRegistry.register('form', …) 的第二个参数(组件元数据)里:

inputs: [
  ...
  { name: 'submitLabel', type: 'string', label: 'Submit Button Label', defaultValue: 'Submit' },
  { name: 'cancelLabel', type: 'string', label: 'Cancel Button Label', defaultValue: 'Cancel' },
  ...
],
defaultProps: {
  submitLabel: 'Submit',
  cancelLabel: 'Cancel',
  ...
},

#3272 / PR #3392 把渲染期的英文默认值去掉了(解构不再写 submitLabel = 'Submit',改为 submitLabel ?? t('common.submit')),于是「作者没写 label」的表单会跟随会话语言。但上面这两处元数据默认值没动。

为什么记一条

defaultProps 在 packages/core/src/registry/Registry.ts 的注释里写的是 “Default props when dropped” —— 设计器把组件拖进画布时的初始 props。如果设计器把它落进作者的 schema,那么设计器生成的每一张表单都带着字面量 submitLabel: 'Submit',对渲染器而言这就是「作者显式写的值」,#3392 的渲染期回落按设计不会覆盖它(显式值逐字优先正是那一单钉住的不变量)。结果就是 issue #3272 描述的那种「不写 label 的作者被静默锁定英文」在设计器这条产出路径上原样保留。

同理 inputs[].defaultValue 会成为属性面板里预填的英文。

为什么标 finding 而不是直接当 bug 排期

今天本仓运行期够不到它:全仓 grep defaultProps,只有两处消费

位置	用途
packages/core/src/registry/Registry.ts:49	类型声明 defaultProps?: Record<string, any>
packages/core/src/registry/WidgetRegistry.ts:185	从 manifest 搬运到 widget 记录

packages/react / SchemaRenderer 渲染路径上没有任何一处读它,所以它今天不影响任何渲染文本。真正会不会咬人,取决于设计器侧(可能在 sibling 仓)拖拽落地时是否把 defaultProps 物化进 schema —— 这一点我没有验证,所以不敢断言严重度,按「填了让 PM 判」处理。

修法建议(先裁决再动)

不建议单独改 form 一个组件:defaultProps / inputs[].defaultValue 里埋英文字面量是全仓约 30 个 renderer 的统一写法(overlay/data-display/navigation 各 renderer 都是),只改 form 会造成一个不一致的孤例。真正要问的是:

• A. 设计器元数据的默认值是否本来就该是「英文的、给设计器物化用的种子」,i18n 只管渲染期回落 —— 那么此条不是 bug,关掉即可,但值得在 Registry.ts 的 defaultProps 注释里写明这个边界,免得下一个人(尤其是 AI 生成的元数据)以为它会跟随语言。
• B. 设计器不该物化「与渲染期默认值等价」的 prop(把 submitLabel 从 defaultProps 拿掉,让它保持未声明)—— 这是与 form.tsx 仍有一批用户可见的硬编码英文(全屏文本编辑对话框、Submit/Cancel 默认值、required aria-label) #3272 同向的收敛,但需要设计器侧确认「未声明」在属性面板里显示成什么(空?占位提示?),并且要一次扫全部 renderer,不是一行改动。

倾向 B,但这属于契约面/设计器交互的裁决,不该由某一单顺手做。

证据等级

静态证据(读 form.tsx 的注册元数据 + 全仓 grep defaultProps 的消费点),未做浏览器复现,也未验证设计器是否物化。「本仓运行期无人读 defaultProps」是可机械复核的事实;「设计器会不会把它写进 schema」是未验证的推断,也正是本条唯一的危害假设。

关联:#3272 / PR #3392。

发现分诊轮(持有):前提 live(defaultProps 仍英文字面),但仓内运行时零读取,危害假设依赖未证实的姊妹仓 designer 物化路径;需先裁 A/B 契约(defaultProps 是否属可物化面)再动 ~30 个 register()。(objectui 分片 PM,会话 session_01GTRjn8xBqp75dk7kFupVRt)

Findings triage (15:47Z fire) — HOLD confirmed, premise re-verified.

Re-checked against origin/main: packages/components/src/renderers/form/form.tsx:2013 still carries the literal submitLabel: 'Submit' in defaultProps. The hold's two load-bearing facts are also unchanged — nothing in this repo reads defaultProps at render time, and the harm hypothesis still depends on an unverified sibling-repo designer materialisation path. So the A/B contract question (is defaultProps a materialisable surface or a designer-only seed?) still has to be answered before touching ~30 register() calls, and answering it by editing one renderer would create exactly the inconsistent outlier the body warns about. Hold stands.

Findings round — held (finding kept).

Premise re-verified on origin/main @ 53b7b88: defaultProps: { submitLabel: 'Submit', … } still present (packages/components/src/renderers/form/form.tsx:2017), and this repo's render path still has no defaultProps consumer beyond the registry type and the manifest copy. Held because the bite depends on an unverified fact outside this repo's render path — whether the designer materializes defaultProps into authored schemas — and the fix direction (A: English seeds are by-design, document the boundary; B: key-ify ~30 renderers' metadata) is a repo-wide design call, not a one-component patch. Restart condition: the designer-side materialization question gets answered, or a designer-produced schema is observed carrying the literal.

Findings-triage re-check (quota round): HOLD maintained (finding stands, no label change).

Premise re-verified on origin/main @ 521a37b: the designer-metadata English literals are still there — submitLabel: 'Submit' in the form component registration's defaultProps at packages/components/src/renderers/form/form.tsx:2095 — while the render-path defaults were localized by #3272/PR #3392, exactly the split this card records. Still nothing reads these at runtime in this repo, so no user hits it today; the leak path (designer baking English defaults into authored metadata) remains hypothetical until a designer surface consumes them. Held.

Findings round (quota re-verification): HOLD maintained (finding unchanged). Re-checked @ origin/main 2b94283: the designer-metadata English literal is live — submitLabel: 'Submit' in the form registration's defaultProps at packages/components/src/renderers/form/form.tsx:2095 — while the render path stays localized per #3272/PR #3392. Still zero runtime readers of defaultProps in this repo; the leak path (a designer surface materializing these into authored schemas) remains hypothetical. Held.

Findings round (quota re-verification): HOLD maintained (finding unchanged). Re-checked @ origin/main a9a67ec: the designer-metadata English literal drifted to form/form.tsx:2105 (submitLabel: 'Submit' in defaultProps), render path still localized per #3272/PR #3392, still zero runtime readers of defaultProps. Leak path remains hypothetical; held.

Findings cadence (triage seat): HOLD — premise re-verified on origin/main @ 6d01319: the designer default submitLabel: 'Submit' literal is still at packages/components/src/renderers/form/form.tsx:2105 (with cancelLabel beside it). Still observation-class: no runtime reader in this repo consumes the designer defaultProps on the render path, so the #3272 render-time fallback is only bypassed for authored-at-design-time schemas. Held; exit is a small i18n sweep whenever the designer-defaults surface is next touched.

Findings triage (cadence re-check): hold continues — finding stays. Re-verified on origin/main @ 9461dd3: the designer metadata literals are still present (submitLabel: 'Submit' in defaultProps at packages/components/src/renderers/form/form.tsx:2117). Still unreachable at runtime in-repo — defaultProps has no live consumer that persists it into authored schemas today; the risk activates with a designer drop-path that writes it. Restart condition unchanged: re-grade when a designer persist path consumes defaultProps.
