finding(sdui-parser/components): the manifest tier reports `unknown-prop` on `body` — the one child-list key 10+ registrations actually honour

[os-sales]

Blocked-by: #6804

Found while completing the container-declaration census for #6764. Out of that card's scope (it is about schema.children and isContainer), and it is a different defect with a different fix, so it is filed rather than swept in.

Measured

validateTree's BASE_PROPS (packages/sdui-parser/src/validate.ts:23) lists children and not body. body appears nowhere else in packages/sdui-parser/src/ either — the string does not occur in the package's source outside tests.

But body is a declared twin of children in the protocol: packages/types/src/base.ts:189 declares body?: SchemaNode | SchemaNode[], and the very next comment line says "Some components use 'children' instead of 'body'."

So a component that renders renderChildren(schema.body) publishes an authoring key the tier does not know. Measured directly against the built parser, with badge's real inputs:

badge + body      -> unknown-prop:    badge has no prop "body"
badge + children  -> not-a-container: badge does not accept children

The second line is correct — badge does not read schema.children. The first is the defect: data-display/badge.tsx:32 renders schema.label || renderChildren(schema.body), so body is exactly the key that works, and the tier gives it the same warning it gives a typo.

This is the #6678 shape on a different key: the one spelling that resolves gets the same unknown-prop as the spellings that do nothing, on the tier built to accept AI-authored pages, where the diagnostic is the contract.

Population, from the #6764 census (runtime, over the live registry)

Of 131 bare authoring tags, 10 render schema.body and never schema.children — so body is their only child-list key:

alert, badge, sidebar-provider, sidebar-header, sidebar-content, sidebar-group, sidebar-menu, sidebar-menu-item, sidebar-footer, sidebar-inset

None of them declares a body input, so none escapes the warning that way. Across the whole renderer tree exactly one registration declares a body input at all (overlay/tooltip.tsx), plus layout/page.tsx's pageMeta, which declares it as Content (Legacy).

A wider set reads schema.children || schema.body (the semantic sectioning tags, the 34 basic/html-elements.tsx tags, basic/div.tsx, layout/aspect-ratio.tsx, form/button.tsx): those authors have a working alternative in children, so the body arm is a silent second dialect rather than the only door.

Two directions, and this needs a ruling rather than a patch

They point opposite ways and the choice is a contract decision, so no recommendation is attached:

A — teach the tier the key. Add body to BASE_PROPS beside children, and extend the containment check so a body child list under a non-container draws not-a-container too. Consequence: body becomes a blessed second spelling of the same concept, permanently.

B — retire the body arm in the renderers. AGENTS.md #0.1 is explicit that a renderer reading two spellings of one concept is the lenient-fallback anti-pattern — "one strict contract beats N dialects" — and schema.children || schema.body is exactly that shape. Consequence: the 10 registrations above lose their only child-list key, so this route needs the ADR-0087-style conversion and a liveness reading on real authored metadata first.

The cheap half of the measurement is done either way: the containment check is guarded by node.children?.length alone, so today no author writing body has drawn a false not-a-container — the hole is silent in both directions.

定级：needs-user-decision · domain:ui · priority:p1。⛔ 不派发。

两条方向都在人工地板上：A 是永久加宽已发布的编写词汇表；B 是退休一个编写键（破坏性，需 ADR-0087 转换 + liveness 读数）。⇒ 我不代裁。

<!-- os-decision-facets -->

（读回：以上为四棱标记，本仓按转义拼写书写——< 直接跟字母会让 MCP 读取静默截断。）

为什么这张值得四棱块（本轮其余 A/B 卡我都跳过了）

因为它永久决定一个已发布的编写词汇：A 之后 body 就是 children 的官方第二拼法，⛔ 撤不回来；B 会让 10 个注册失去唯一的子列表键。两边都不可逆，这正是四棱要处理的形状。

四棱

① 项目长远合理性 — AGENTS.md #0.1 明写「one strict contract beats N dialects」，而 schema.children || schema.body 正是它点名的 lenient-fallback 反模式。⇒ 本轴明确指向 B。⚠️ 但同一条原则也说明 A 会把一个反模式写进契约，那是长期成本，不是一次性成本。

② 实际业务拉动 — ⛔ 拉动当前为零：卡已测出容纳检查只看 node.children?.length，所以今天没有任何写 body 的作者收到过假的 not-a-container。⇒ 无人在流血。⚠️ 但这个零是沉默造成的，不是"没问题"。

③ 防 AI 犯错 — ⭐ 本卡最尖的一面，且后果比"误导"更重：在这个专为 AI 编写页面而建的 tier 上，诊断即契约。今天一个 AI 作者在 alert / badge / 8 个 sidebar 标签上写 body（那是这 10 个注册唯一能用的子列表键），得到的是 unknown-prop: has no prop "body"。

⇒ ⛔ 这个假诊断不只是误导，它开出了一个会把页面改坏的处方：作者照它把 body 改成 children，而这 10 个注册根本不读 children ⇒ 子节点静默消失。从一个能渲染的页面，被诊断引导到一个渲染不出来的页面。 这是 p1 的理由。

④ 创业阶段不扩散 — A 是一行 BASE_PROPS 加一个容纳检查分支，今天就能做完。B 需要 ADR-0087 转换 + 对真实已编写元数据的 liveness 读数 + 10 个注册的迁移 ⇒ 是一个项目，不是一次修复。⇒ 本轴明确指向 A。

⚠️ ①④ 直接对立，这就是它必须由人裁的原因。

选项 × 客户真正能感知到的代价

	做法	客户感知
A	BASE_PROPS 加 body，容纳检查同时认 body 子列表	✅ 假诊断立刻消失，10 个标签可正常编写。⛔ 代价：body 永久成为官方第二拼法，此后每个新注册的作者都要问"该用哪个"，且 AI 作者会两种都学。
B	退休渲染器里的 body 分支	✅ 一个概念一个拼法。⛔ 代价：10 个注册失去唯一子列表键 ⇒ 已编写的页面会坏，除非先做转换；且需要一次真实元数据的 liveness 读数，而那正是本会话反复够不着的东西（生产普查）。
A′	先做 A 止血，同时立一张 B 的转换卡	✅ 立刻不再误导 AI 作者；⛔ 代价：B 变成有主的债，而债经常不还——本仓已有多例（#13014 族）。

推荐（一个建议，不是裁决）

A′。理由是不对称的风险：③ 的伤害今天正在发生（每一个写 body 的 AI 作者都被引向一个更坏的页面），而 ① 的伤害是长期且可逆（B 随时可以再做，转换工作量不因为先做了 A 而变大）。⇒ 先止住正在流的血，再还结构债。

兜底：若不接受"债会被还"，则直接裁 A 并明确承认 body 是永久第二拼法——⛔ 比裁 A′ 然后让 B 烂在队列里更诚实。

⚠️ 置信缺口（必填）

1. 我没有独立复核那个 10 个标签的名单，也没核 overlay/tooltip.tsx 是唯一声明 body 输入的注册。均为转述。⚠️ 若那 10 个里有些其实也读 children，B 的代价会显著下降，推荐可能翻转。
2. 未测：真实已编写元数据里有多少页面在用 body。 这正是 B 需要而本会话够不着的生产读数（与 objectstack#12920 同形）。⇒ ⛔ 不要把 B 挂在一个等不到的普查上。
3. 我未核 packages/types/src/base.ts:189 那条声明与它下一行注释的确切措辞——而那条声明正是"body 是协议里已声明的孪生键"这个论点的全部依据。⚠️ 裁前值得核一眼：若 body 在协议里其实已被标为 legacy，A 就变成"把 legacy 扶正"，性质不同。

裁后执行

• 裁 A / A′ ⇒ 转 pm:queue · domain:ui，范围＝BASE_PROPS 加 body + 容纳检查认 body 子列表；A′ 另立 B 的转换卡。
• 裁 B ⇒ 转 pm:blocked，先做 ADR-0087 转换与 liveness 读数，⛔ 不得直接删渲染器分支。
• ⛔ 裁定落地时请挂 pm:retriage（预登记的条件改判不会自动触发，objectstack#13037 前科）。

低摩擦裁决：回「A」「A′」或「B」即可。

⚠️ 分母更正:body-only 族是 13 个键,不是裁决执行要点里写的 10

在实施 #6779(容器声明普查)时测出,本席已独立复核。本卡尚未派发,所以这条赶在派发之前落卡 —— 否则接手的 dev 会照 10 去做。

裁决执行要点第 1 条写的是:

10 个 body-only 渲染器(alert、badge、8×sidebar-*)补 children 读法

实际构成:

	数
alert	1
badge	1
sidebar-* 族	11
合计	13

这个数我自己核过,而且第一次核错了 —— 记下来省得下一个人重犯

第一次我用 sidebar-[a-z-]+ 去数,得到 10:

sidebar-content  sidebar-footer  sidebar-group   sidebar-header
sidebar-inset    sidebar-menu    sidebar-menu-button
sidebar-menu-item sidebar-provider sidebar-trigger

⇒ 差的那一个是裸键:packages/components/src/renderers/navigation/sidebar.tsx:57 是 ComponentRegistry.register('sidebar', …),没有连字符后缀,被我的正则排除在外。10 + 1 = 11。

⛔ 教训写在这里而不是别处:数一个「前缀-* 族」时,要求后缀的正则会静默丢掉那个裸的族名键。本卡的迁移清单如果用同形状的查询生成,会漏掉同一个键 —— 而它恰好是这一族里最可能被 host 直接引用的那个。

对本卡的影响

• 执行范围从 10 个渲染器变成 13 个。
• ⛔ 裁决本身不动 —— 方向 B(渲染器侧退役 body 方言)与它的硬前置(先跑 body 的存量普查,带 children 命中数作正控)完全照旧。变的只是执行要点第 1 条的那个计数。
• ⚠️ 硬前置的门槛(「存量达三位数节点 ⇒ 停手回报」)也应当按 13 个渲染器的实际存量重新读,而不是照 10 个渲染器时的预期。

另一条来自 #6779 的相关读数

#6779 的实施报告称:那三种例外形状(tabs、void 标签 img/hr/br、以及 body-only 族)不需要具名排除清单 —— 它们在运行时谓词下本来就不算容器,因为没有一个会把 authored child 放上页面,所以是按构造被排除的,没有任何东西是靠名字跳过的。

⇒ 这对本卡是个好消息:说明这 13 个渲染器今天不违反容器声明那条规则,本卡对它们补 children 读法与 #6779 的 ratchet 清单不冲突。⚠️ 但该报告同时说它把这三种形状钉成了对谓词本身的 pin,所以「把谓词改写成源码侧的 children OR body 拼法」会变红。⇒ 本卡实施时若动到那个谓词的形状,预期会撞上那条 pin —— 这是设计如此,不是回归。

⚠️ Cross-card collision notice — triage seat (R+26, session session_011c4YfanSNzNEVaHhDuSAfB)

⛔ No label, grade or scope change here — this card stays pm:queue · domain:ui · priority:p1 and its ruling is untouched. This is a dispatch-time warning only, filed because this card is unassigned and dispatchable right now.

One expression sits inside two same-day rulings

packages/components/src/renderers/form/button.tsx:58:

{schema.label || renderChildren(schema.body || schema.children)}

card	what its ruling wants from this line
this card (#6771)	retire the body dialect — point 3 says renderers reading children || body drop the body arm in the same change ⇒ reaches this line literally
#6804 (needs-user-decision, p1)	button was deliberately carved out of #6779's ratchet list and is awaiting a maintainer ruling on whether it declares isContainer

⇒ read literally, this card's execution edits an expression another card is currently suspended on.

What this does and does not mean

• ⛔ The two are NOT in conflict on semantics. [Decision] What instrument stops the container-declaration class regenerating — and do the remaining 45 get fixed before it lands? #6779/[Decision] Should button declare isContainer? — the one public hit among the 53, carved out of #6779 by ruling #6804 is about isContainer (layout containment); this card is about the body dialect. Different questions, ⛔ do not read this as needing either ruling revisited.
• ⚠️ They are in conflict about who edits the line. [Decision] Should button declare isContainer? — the one public hit among the 53, carved out of #6779 by ruling #6804 was filed under a ruling that explicitly reserves the button public-tier trade-off as a product decision for the maintainer. A body-arm removal landing there first changes the expression that decision is being made about.

The ask — one sentence in the dispatch, ⛔ not a block

The dispatch order for this card must state explicitly whether button.tsx:58 is IN or OUT of its body-arm removal.

• OUT (recommended by triage, ⛔ not ruled): leave the line alone, name it in the派发令's exclusion list with the reason (button is suspended on [Decision] Should button declare isContainer? — the one public hit among the 53, carved out of #6779 by ruling #6804), and remove the body arm everywhere else. Costs this card nothing — button is one site — and keeps [Decision] Should button declare isContainer? — the one public hit among the 53, carved out of #6779 by ruling #6804's subject stable.
• IN: acceptable, but then [Decision] Should button declare isContainer? — the one public hit among the 53, carved out of #6779 by ruling #6804 must be told the expression moved, because its option-A/B costs were written against the current line.

⛔ Not pm:blocked. The dependency is one line out of this card's population, not availability — blocking a p1 dialect retirement behind a maintainer decision on a single renderer would be the invisible-blocker shape this seat does not create. A named exclusion is the right instrument, and answering it is the claiming seat's job at dispatch time.

Raised because #6804 flagged the shared line and this card is unassigned — ⇒ the collision is live today, not hypothetical. Full context on #6804.
