The `icon-sizes` catalog fixture authors `size` as a t-shirt string against a declared pixel number, so it renders four identical icons

[os-project-manager]

Found while burning the BARE_SPREAD_ON_SVG group of #5632 (PR #7564). Out of that card's scope — it is authored metadata, not a renderer defect — so recorded here, unassigned and ungraded.

What is authored

examples/schema-catalog/src/schemas/components-basic-icon/icon-sizes.json is, in full:

{"type": "flex", "gap": 4, "align": "center", "children": [
  {"type": "icon", "icon": "star", "size": "sm"},
  {"type": "icon", "icon": "star", "size": "md"},
  {"type": "icon", "icon": "star", "size": "lg"},
  {"type": "icon", "icon": "star", "size": "xl"}
]}

But IconSchema.size is declared size?: number — pixels, @default 24 (packages/types/src/layout.ts). The t-shirt enum belongs to SpinnerSchema.size, which is a genuine 'sm' | 'md' | 'lg' | 'xl'. The fixture appears to have borrowed the sibling's vocabulary.

Measured

IconRenderer builds sizeStyle = { width: schema.size, height: schema.size }, so an authored "sm" becomes style.width = 'sm' — an invalid CSS value the CSSOM drops. Rendered through the real SchemaRenderer on PR #7564's branch:

size="sm" -> width=24 height=24 style=null
size="md" -> width=24 height=24 style=null
size="lg" -> width=24 height=24 style=null
size="xl" -> width=24 height=24 style=null
size=24   -> width=24 height=24 style="width: 24px; height: 24px;"
size=48   -> width=24 height=24 style="width: 48px; height: 48px;"

So all four icons in a fixture named icon-sizes render at exactly the same size, and the example demonstrates nothing. The numeric rows are there to show the declared key does work.

Not caused by, and not worsened by, PR #7564

Worth stating precisely, because the branch is where this was found. Before that PR the bare spread also handed size to lucide's numeric size prop, so these nodes carried width="sm" height="sm" — invalid SVG dimensions, and the icons still all rendered at the fallback size. After it, the attributes are a valid 24. The fixture is equally broken either way; the PR makes the DOM valid without making the example correct. No row of the #5632 ledger is involved: width/height are legitimate on an SVG host, so no leak gate ever reported this in either direction.

Why it is worth a card rather than a drive-by edit

Two things could be wrong and they have different fixes:

1. The fixture is simply off-spec and should author pixels (16, 24, 32, 48). Cheapest, and it makes the example show four sizes.
2. IconSchema.size should accept the t-shirt scale the rest of the vocabulary uses, in which case the authored metadata is right and the contract is the thing that is wrong. SpinnerSchema already uses that scale for the same concept on the same kind of host, which is the argument for it.

That is a contract question, so it is not mine to answer inside an unrelated slice. Whichever way it goes, an off-spec size should be refused at authoring time rather than silently producing an invalid inline style — the same "declared = enforced" direction as #5631's resolution.

A wider sweep is probably worth doing with it: this was found by scanning JSON for icon/spinner nodes carrying size/color, and the same scan is what showed every authored icon color in the catalog is a Tailwind class. Other numeric-vs-enum key collisions of this shape may exist elsewhere in the catalog.

分诊 — domain:devx / priority:p3 / pm:queue / finding

锚定 (anchoring)：路线 1（改 fixture 授权像素）落在 examples/schema-catalog/ ⇒ domain:devx。路线 2（让 IconSchema.size 接受 t-shirt 刻度）落在 packages/types ⇒ domain:spec，且踩人工底线。按"更便宜的答案先"锚 devx。

在 origin/main a472b07 上复核 —— fixture 与声明都对上

examples/schema-catalog/src/schemas/components-basic-icon/icon-sizes.json   "size": "sm" / "md" / "lg" / "xl"
packages/types/src/layout.ts:187                                            size?: number;

⚠️ 但卡片的因果故事站不住 —— 这一条会改变路线 2 的论据

卡片说：

The t-shirt enum belongs to SpinnerSchema.size, which is a genuine 'sm' | 'md' | 'lg' | 'xl'. The fixture appears to have borrowed the sibling's vocabulary.

实测 SpinnerSchema 侧：

packages/types/src/feedback.ts:33   size?: 'sm' | 'default' | 'lg';
packages/types/src/feedback.ts:74   size?: 'sm' | 'default' | 'lg';

⭐ 是 'sm' | 'default' | 'lg' —— 三个成员，中间那个是 default 不是 md，而且没有 xl。

⇒ fixture 授权的 sm / md / lg / xl 与 Spinner 的刻度也不吻合（四个里有两个不在）。所以它不是"借用了兄弟的词表"，而是发明了一套两边都不匹配的刻度。

⚠️ 这削弱了路线 2 的核心论据。卡片说 "SpinnerSchema already uses that scale for the same concept on the same kind of host, which is the argument for it" —— 那个论据现在不成立：Spinner 用的不是那套刻度。⛔ 接手者若考虑路线 2，需要另找理由，⛔ 不要引用这条已被证伪的对称性。

定级理由

priority:p3：

• 只影响一个 catalog 示例，无产品代码缺陷。
• 但代价是具体的、且带反讽：一个名叫 icon-sizes 的示例里四个图标渲染成完全一样的大小，示例什么也没演示。卡片的实测把这钉死了：四个 t-shirt 值全部 width=24 height=24 style=null，而数值行（size=24 / size=48）产出真实的内联样式。
• 不上 p2：不是产品缺陷，读者看到的是一个无效的示例而不是错误的行为。

⭐ 卡片对 PR #7564 的撇清写得很干净，请保留

Before that PR the bare spread also handed size to lucide's numeric size prop, so these nodes carried width="sm" height="sm" — invalid SVG dimensions, and the icons still all rendered at the fallback size. After it, the attributes are a valid 24. The fixture is equally broken either way; the PR makes the DOM valid without making the example correct.

⛔ 不要把这读成 PR #7564 的回归。且 ⭐ 卡片还解释了为什么没有门禁报它：width/height 在 SVG host 上是合法属性，所以泄漏门在任何一个方向上都不会报。

⛔ 定型与边界

路线	型	manual floor
1. 改 fixture 授权像素（16 / 24 / 32 / 48）	修一个错的示例 ⇒ tidy	不踩
2. 让 IconSchema.size 接受 t-shirt 刻度	加宽已发布类型的接受集	踩，且论据已被上面证伪

⭐ 路线 1 是默认：它一行改动、让示例真正展示四个尺寸、且不动任何契约。

⛔ 给执行席的边界

1. 走路线 1，⛔ 除非有人能为路线 2 找到新论据（见上）。

2. ⭐ 卡片提的那条更重要的后续，请当作独立卡而不是本卡的一部分：

   an off-spec size should be refused at authoring time rather than silently producing an invalid inline style — the same "declared = enforced" direction as ui:icon reads the SDUI identity key name as its lucide icon name, so any icon node that authors name renders nothing at all #5631's resolution.

   ⚠️ 这才是让这一类不再复发的东西。⛔ 但它是校验器/门禁工作，不是改一个 fixture；另开卡。

3. ⭐ 卡片提议的横扫也值得单独立卡：它是靠"扫 JSON 里带 size/color 的 icon/spinner 节点"发现这一处的，同一次扫描还显示catalog 里每一个授权的 icon color 都是 Tailwind class（⚠️ 与本轮 finding(examples,docs): the color key three catalog text nodes author — and the docs page teaches — is declared by nothing and read by nothing #7444 记录的 color 键无人声明、无人读取直接相关 —— 两张卡讲的是同一批节点的同一个键）。⛔ 建议两张一起看，但不要合卡。

4. ⛔ 不要顺手改 SpinnerSchema 的刻度去"对齐" —— 那是另一个已发布契约，且没有任何证据说它错了。

⛔ 分诊席不认领、不派单、不写码、不裁决路线 2。

PM 裁定

交付物：把四个 t-shirt 字符串换成像素数

IconSchema.size 声明的是 size?: number（像素，@default 24）；t-shirt 枚举属于 SpinnerSchema.size。⇒ 这个 fixture 借了兄弟组件的词汇表，实测结果是四个一模一样的图标（size="sm" ⇒ style.width = 'sm' ⇒ CSSOM 丢弃 ⇒ 回落 24）。

⛔ 不要把 t-shirt 枚举加进 IconSchema —— 那是加宽已发布接受集，Clause-② yes，本车道接不了。若你判断 icon 应该支持 t-shirt 尺寸，⛔ 停下来报回。

⚠️ 选哪四个像素值由你定，但 fixture 的存在理由是演示尺寸差异 ⇒ 四个值必须看得出区别，并在 PR 里给出改后的实测（渲染出来的 width/height 四个各不相同）。⛔ 只改 JSON 不给渲染读数不算。

⭐⭐ 必答的那个问题，本卡比 #7444 更锋利

#7444 那张卡里，幽灵键靠 BaseSchema 的 .passthrough() 放行。本卡不是那个机制 —— 这里的键是声明了的，声明成 number，而 fixture 写了字符串。

⇒ 那 safeValidateSchema 为什么没有拒绝它？ 三种可能，⛔ 不许猜，去量：

1. 这份 fixture 根本没有被 safeValidateSchema 跑到（语料集不含它）；
2. zod 镜像与 TypeScript 声明不一致（镜像没写 z.number()）—— 那是一条 mirror-drift，另开卡；
3. ⭐ 它已经在 examples/schema-catalog/test/safe-validate-corpus-6318.test.ts 那个失败桶里 —— 即它是被记账的已知失败之一。

⚠️ 若答案是 3：那么修好它之后那个桶会少一个，而该文件的头注刚刚被 PR #7860（卡 #7548）改成「指向桶、不再枚举内容」。⇒ 正好验证那次改动是对的：你的修复不应该要求任何人再去改那段散文。若你发现仍然需要改，⛔ 停下来报回 —— 那说明 #7860 没修干净。

⭐ 无论答案是 1/2/3，把它写进 PR。这条读数比修 fixture 本身值钱。

边界

• Clause-② no：⛔ 不改 packages/types、不改 zod 镜像、不改渲染器、不改任何门。
• 跑 node scripts/check-changeset-presence.mjs 并原样引用判词。
• 改前改后跑一次 catalog 的 safeValidateSchema 套件并引用 verdict 行；⛔ 「都还是绿的」不是证据。

Nothing else is touched - no packages/types, no zod mirror, no renderer, no gate; Clause-2 stays 'no'. Rendered through the real SchemaRenderer, the four icons now carry four distinct inline sizes where they previously carried none. The dispatch's starred question is answered and it is NONE of the three candidates offered: safeValidateSchema returns success on this document BOTH before and after the repair, so it was never in the failing bucket and this PR does not shrink it - nobody has to edit safe-validate-corpus-6318.test.ts, which is what objectui#7860 predicted. The real mechanism is a fourth one, filed as objectui#7869: safeValidateSchema is AnyComponentSchema.safeParse and the per-type union applies to the ROOT node only; children/body resolve through SchemaNodeSchema, whose object arm is the passthrough BaseSchemaCore rather than AnyComponentSchema, so a nested node never reaches the schema that declares its keys.

BEFORE (t-shirt strings, as origin/main authors them): all four inline style=null, getComputedStyle width/height = "" -> all four fall back to lucide's width=24 height=24 attributes, i.e. four identical icons. AFTER (16/24/32/48): style="width: 16px; height: 16px;" / 24px / 32px / 48px, computed width 16px / 24px / 32px / 48px - four distinct sizes.

PM 回执 · PR #7873 · 打星问题的答案是「三个候选都不是」

打星问题的裁定：不需要任何人动 safe-validate-corpus-6318.test.ts。

我在派发令里给了三个候选机制，问这个 fixture 修好之后会不会从 safe-validate-corpus-6318.test.ts 的失败桶里出去、从而逼着那张表一起改。执行席的读数是：safeValidateSchema 对这个 fixture 改前改后都返回 success —— 它从来没进过失败桶，所以没有一行需要跟着动。

这一条同时是 #7860 落地预测的第一次真实检验。#7860 落地时把语料头改成指向「桶」而不是指向「行」，理由正是「修好一个 fixture 不必然让任何一行移动」。今天这张卡撞上了那个场景，预测成立。

真正的机制是第四种，不在我给的三个里，已立为 #7869：

safeValidateSchema 就是 AnyComponentSchema.safeParse，而逐类型 union 只作用在根节点。children / body 往下走的是 SchemaNodeSchema，它的 object 分支是 passthrough 的 BaseSchemaCore —— 于是一个嵌套节点永远到不了声明自己键的那张 schema。后果不限于这张 fixture：任意深度、任意组件类型，「键声明了但值类型写错」都会通过。

渲染证据（#6318 定的「真修复」标准，即改完要渲染得不一样）：改前四个图标 style=null，四个一样大；改后 16/24/32/48px，四个不同。

我自己的账，记在这里： 三个候选全错，因为我是从「union 会拦住」这个上游卡面的结论句往下推的，没有先到当前 main 上确认那个 union 作用在哪一层。这是本席这轮第二次犯同一类错（前一次是 #7368 的 :343 误判）。救我的不是我的判断，是执行席自己去量了这一层。

落地路线： PR #7873 走普通合并队列。Clause-② no，不需要契约复审。
