examples/schema-catalog: 48 个示例仍用已废弃的 `div` 组件类型,docs 站每张缩略图都刷一条 deprecation warning

[yinlianghui]

发现于 #3903 的浏览器实证(PR #3964),不在该 PR 处理 —— 那一单改的是索引页卡片的 DOM 结构,这一条是目录示例 JSON 的内容问题,与卡片外壳无关。

现象

/docs/guide/schema-catalog 上滚动加载缩略图时,控制台反复刷:

[ObjectUI] The "div" component is deprecated. Please use Shadcn components instead:
  - For containers: use "card", "flex", or semantic layout components
  - For simple wrappers: use layout components like "container", "stack", or "grid"
See documentation at https://www.objectui.org/docs/components for alternatives.

来源是 packages/components/src/renderers/basic/div.tsx:17-24(DivRenderer 在 NODE_ENV !== 'production' 时每次渲染都 console.warn,没有去重)。

命中面:grep -rl '"type": "div"' examples/schema-catalog/src/schemas | wc -l = 48 个示例(全目录 423 个)。同族的 span 渲染器也带同样的废弃警告,但目录里 "type": "span" 命中 0,所以现在只有 div 这一支。

修 #3903 之后该页 Next dev 指示器仍报 10 个 issue,就是这些警告(嵌套按钮的 2 条已归零:12 → 10)。

为什么归为 observation-class

• 只在非 production 构建下 console.warn,docs 站生产构建里用户看不到;今天没有用户会撞到。
• 但它是目录本身的作者面问题:目录是「每个示例都是该写法的范本」这一契约的载体,48 个范本示范的是引擎自己标记为废弃的类型。AI 生成 metadata 时正是照着这些范本抄的,所以这批 JSON 的示范价值是负的。
• 附带的次级问题:DivRenderer 的警告没有 per-type 去重,一页 400+ 缩略图会把控制台刷满,把真正的报错埋掉(apps/site: Schema Catalog 索引页把每个缩略图包在 button 里,85 个含 button 节点的示例都触发 React 嵌套按钮 hydration 报错 #3903 的两条嵌套按钮报错就是在这堆噪声里被捞出来的)。是否要给废弃警告加 once 语义,是与「换掉 48 个示例」不同的一个决定,留给分诊。

参考位置

• packages/components/src/renderers/basic/div.tsx:17-24(警告来源,无去重)
• packages/components/src/renderers/basic/span.tsx(同族警告,目录内暂无命中)
• examples/schema-catalog/src/schemas/**(48 个含 "type": "div" 的示例)

Findings triage (first grading) — HOLD: finding retained.

Premise check on origin/main @ cdc0e44: warning source verified at packages/components/src/renderers/basic/div.tsx:17-24 (console.warn gated on NODE_ENV !== 'production', no dedup); catalog hit count re-measured at 47 files containing "type": "div" under examples/schema-catalog/src/schemas (card says 48 — one example has evidently been touched since filing; the surface stands).

Why hold: dev-build-only console noise — production docs-site users see nothing, so no user hits this today. The real cost is authoring-contract quality (48 catalog exemplars demonstrating a type the engine itself deprecates, and AI-generated metadata copying them) plus the missing once-semantics burying real errors during dev — both true, neither urgent, and the card correctly notes they are two separate decisions (content swap of 47 examples vs adding warn-dedup to the renderer family).

Restart conditions — any one promotes:

1. A sweep-pack forms: the 47-example content swap is naturally one sweep card (one claim, one PR, mechanical div → layout-component replacement per the warning's own guidance) — promote when a sweep batch is assembled rather than as a lone card;
2. The div/span deprecation graduates to removal or a hard error — at that point the catalog breaks outright;
3. A second dev-noise incident is recorded where the un-deduped warning buries a real error (first one already logged: apps/site: Schema Catalog 索引页把每个缩略图包在 button 里,85 个含 button 节点的示例都触发 React 嵌套按钮 hydration 报错 #3903's nested-button errors) — that promotes the once-semantics half on its own.

Dedup: repo-scoped search on schema-catalog div deprecation / DivRenderer — clean; #3903 / PR #3964 (discovery site) changed the card shell only.

PM 分诊轮(session_01GTRjn8xBqp75dk7kFupVRt):finding → 晋级 pm:queue。理由:虽仅 dev 构建可见,但 48 个 catalog「范本」示范引擎自己标记废弃的 div 类型,对照抄的 AI metadata 会继承 —— 这是文档第二轴的实害;且无去重的 console.warn 在缩略图页刷屏埋掉真报错,已两次干扰浏览器实证(PR3964/PR3953)。范围:48 个 JSON 换正当类型(按各示例语义选 container/box 等既有类型,不是机械替换)+ div.tsx 的 warn 去重(一次性提示);两方向钉。派发时与 catalog 面在飞单互斥检查。

🔒 认领(objectui 分片 PM,session_01GTRjn8xBqp75dk7kFupVRt,批次 6)。分支 claude/issue-3965-catalog-div-retirement;范围按分诊评论:48 个 catalog JSON 的废弃 div 换正当类型(按语义逐个选,非机械替换)+ div.tsx 的 deprecation warn 去重;两方向钉。文件面:examples/schema-catalog/src/schemas/** + packages/components/src/renderers/basic/div.tsx;与同批 #3968(同目录但只碰 test/tsconfig/scripts)文件不相交,派发词互相声明边界。
