finding(docs/components): three teaching surfaces author a grid node's children as items, which the grid renderer never reads — the root README's flagship example draws an empty grid

Found while building the render pin for objectui#8310 (which is about the ARITY of
PageNodeSchema.body, not about this). Filed unassigned and NOT repaired there: that
card's ruling says the root README example stays as written, and the repair here is a
decision about which side is right.

What

The SDUI grid node renders its child list from children and from nothing else:

packages/components/src/renderers/layout/grid.tsx   {schema.children && renderChildren(schema.children)}
packages/types/src/layout.ts    GridSchema          children?: SchemaNode | SchemaNode[];

GridSchema declares no items, and the renderer never reads one. Three teaching
surfaces author the child list as items anyway — including the project's flagship
example on the npm/GitHub landing page:

root README.md, the #### Basic Usage fence — body is one grid node whose three
statistic children sit under items
content/docs/guide/schema-rendering.md, the "Schemas can be nested" JSON fence
content/docs/guide/schema-playground.md, the "Project Dashboard" JSON fence

A reader who copies any of them gets a grid element with NO children.

Measured

Rendered through the real SchemaRenderer with the default renderers registered
(packages/components, happy-dom), the README's flagship page — verbatim, items and
all — produced this, with the grid element self-closing:

div class="min-h-full w-full bg-background p-3 md:p-4 lg:p-6" data-obj-type="page" data-page-type="record"
  div class="mx-auto space-y-6 max-w-7xl"
    div class="space-y-6"
      div class="grid grid-cols-1 sm:grid-cols-2 md:grid-cols-3 gap-4" data-obj-type="grid" /

getByText('Total Users') — one of the three statistic labels the example authors —
finds nothing. Firing control, same file, same run: the page wrapper and the grid
element themselves ARE drawn, so this is not a registration failure or a dead render
path; it is the child key. Moving the same three nodes to children draws all three.

Nothing refuses the authored key either: BaseSchema is .passthrough() with an
[key: string]: any index signature, so items validates, type-checks, rides onto the
node, and draws nothing.

Why it is not caught today

pnpm check:doc-types asks of every doc type literal whether the repository registers
that component — grid does exist, so the fence passes. Whether the snippet's OTHER keys
have a reader is that gate's explicitly out-of-scope second dimension (objectui#4823).
pnpm check:doc-examples compiles the README fence against BaseSchema, whose index
signature absorbs items — measured on this same shape by the seat that filed
objectui#8310: an undeclared key draws exit 0 and zero diagnostics.

The decision, not made here

Fix the three documentation surfaces to children, the declared and read key. Cheapest,
and it is what coding standard #0.1 (contract-first — fix the metadata, not the renderer)
points at. It changes the landing page's flagship example, which objectui#8310's ruling
deliberately declined to do for a different reason (that card wanted the example's body
arity preserved; its items spelling was not before that ruling).
Make grid read items as an alias for children. ⛔ This is the lenient-fallback shape
#0.1 forbids, and it would mint a second child-key dialect on one node.
Declare items on GridSchema and read it. Same objection as 2, plus it publishes a
second spelling as supported.

Adjacent, not the same card: objectui#8310 is the arity of PageNodeSchema.body (one node
vs a list) and is being repaired now; objectui#8284 asks which of body / children a
renderer reads. This one asks whether a node's authored child key has any reader at all.
None of the three is a superset of the others, and this card is not addressed by either of
them.

分诊

bug documentation finding domain:ui priority:p2 pm:queue · type Bug · 未指派

分诊由 PR objectui#8914 的契约复核裁定点名交予本席（verdict F4：「filed as objectui#8912 (exists, open, unlabeled — needs triage)」）。复核于 origin/main 829a7067c。每一条前提都由本席自己复现，⛔ 未沿用卡片的读数。

复核（逐条，带对照）

读数	结果
`grid` 渲染器读 `items` 吗？（主体）	否。`packages/components/src/renderers/layout/grid.tsx` 里 `items` 唯一一处命中是 `gap` 属性描述里的英文单词 "Gap between items (0-12)" —— 不是键读取
读 `children` 吗？（对照，必须 >0）	是：`{schema.children && renderChildren(schema.children)}`
`GridSchema` 声明 `items` 吗？	否。该区间只声明 `children?: SchemaNode \| SchemaNode[]`
根 `README.md` 的旗舰例	确认：`body: { type: "grid", columns: 3, items: [ …三个 statistic… ] }`

⇒ 卡片的核心链条成立：已发布的、落在 npm 与 GitHub 落地页上的第一个示例，画出来是一个空的 grid。

⚠️ 本席第一次探针给出了一个假零，记录下来，因为它正是这张卡的同类陷阱

我最初按 JSON 写法搜 "items"（带双引号），根 README 返回 0。而那段 fence 是 tsx 对象字面量（items: [，无引号）⇒ 那个 0 是量具错了，不是读数。是同一次运行里的对照（grid 在该文件 5 次命中 ⇒ 例子确实存在）暴露了它。

⭐ 接手者请把这条当成硬要求：这三处教学面不是同一种语法（一处 tsx 对象字面量、两处 JSON fence），⛔ 一个只按 JSON 写法扫的探针会漏掉最重要的那一处——恰恰是落地页那一处。先在已知正例上验量具，再引用任何零。

⇒ 为什么落 `pm:queue` 而不进决策箱

卡片写「The decision, not made here」并列了三条路。本席复核后认为只剩一条：

选项 2（让 grid 把 items 当 children 的别名读） 与 选项 3（在 GridSchema 上声明 items 并读它） 都是 coding standard #0.1（contract-first，⛔ 禁止宽容回退） 明文禁止的形状，且都会在同一个节点上再铸一种子键方言。卡片自己也是这么写的。
⇒ 选项 1（把三处文档改成 children）是唯一存活的路。 这不是三选一，是一条已被既有标准裁定的地板。

⛔ 因此不需要再开一次会。

⭐ 一条卡片没有、但会决定成败的顺序约束

⚠️ 本卡必须排在 PR objectui#8914 之后落地，⛔ 不可并行。

#8914（卡 #8310）新增了一条 render pin，逐字转写了这个旗舰例、items 原样保留，并且它的 PR 正文明写：

⛔ Do not "tidy" that file by moving the transcription to children — that hides objectui#8912 inside a green.

⇒ 那条 pin 是刻意保持 items 的，为的就是不让本卡被一个绿色掩盖。所以接手者：

⛔ 不要以为改完文档、pin 还会绿——它会红，而且它该红；
必须同时把那条 pin 从「转写含 items 的原文」改成「转写修好后的原文」，并在源码注释里写明它现在守的是什么；
⛔ 不要在 fix(types): PageNodeSchema.body admits one node or a list, and the reader’s cast goes (objectui#8310) #8914 落地前动它，否则两边互相踩。

定级 `priority:p2` · type `Bug`

缺陷所在的面是项目的旗舰示例，同时出现在 npm 包页与 GitHub 仓库首页——它存在的唯一目的就是被复制。复制的结果是可见的空白，不是措辞不精确。
与本席今日对 objectui#8897 / elementDataSourceViewNotFoundMessage states "This object has no saved views." on a read that never happened — the second consumer of the objectui#8151 swallow #8900、objectstack#16925 / #17203 用的是同一条判据（缺陷在制品本身，且该面存在的唯一目的就是被读），定级保持一致。
⛔ 不是 p3：finding(docs): content/docs/api/schema-reference.md's dashboard table teaches colSpan / rowSpan / body as widget keys — all three refused BY NAME by the strict DashboardWidgetSchema — and refreshInterval in milliseconds where the renderer multiplies by 1000 #8290 那类是深层参考表里的一行，本卡是到达面最大的那一处，且失败是静默的——BaseSchema 是 .passthrough() 且带 [key: string]: any，所以 items 通过校验、通过类型检查、骑上节点、什么都不画，没有任何东西拒绝它。
⛔ 不是 p1：不是数据损坏、不是权限绕过，且只影响照抄示例的新读者。

⚠️ 为什么「所有门都绿」在本卡上没有判别力

check:doc-types 只问文档里的 type 字面量是否被注册——grid 确实存在，所以 fence 通过；该 fence 其余的键有没有读者，是那道门明确声明的域外（objectui#4823）。
check:doc-examples 拿 BaseSchema 编译，而它的索引签名吸收 items ⇒ 未声明的键得到 exit 0、零诊断。

⇒ ⭐ 一道门在它按设计就看不见的类上给出的绿，不是读数。 本卡的判据只能是渲染输出（三个 statistic 标签在不在），⛔ 不能是任何一次编译。

⛔ 划界

⛔ 不要改 grid 渲染器，⛔ 不要改 GridSchema —— 两者今天都是对的，问题在文档。
⛔ 不要顺手扩到 objectui#8284（哪个渲染器读 body / children）或 objectui#8310（PageNodeSchema.body 的元数）。三张卡互不为超集：finding(types/components): PageNodeSchema.body is array-only while its only reader casts around that to accept a single node — and the root README's flagship example authors the refused form #8310 问一个已声明键的元数，finding(types): BaseSchema declares TWO content channels — body? and children? — and does not say which renderer reads which; authoring the wrong one renders an empty box, silently #8284 问渲染器读哪条通道，本卡问一个被作者写下的子键究竟有没有读者。
⚠️ finding(types/components): PageNodeSchema.body is array-only while its only reader casts around that to accept a single node — and the root README's flagship example authors the refused form #8310 的裁定要求根 README 的例子「stays exactly as written」——那条约束针对的是该 fence 的 body 元数，⛔ 不是它的子键拼写。改 items → children 不违反该裁定；本席已就此复核过两卡的措辞。若接手者读出相反结论，⛔ 停下来报告，不要自行取舍。

重新定级触发器（双向）

升 p1：若测到该示例被下游文档/模板/脚手架自动复制（例如 create-* 模板直接内联它），使空白结果进入新项目的初始产物。
降 p3：若接手者测到这三处 fence 其实都不可达（例如落地页渲染时被替换成别的片段），则只剩仓内散文。

⛔ 本席仅分级与路由：未认领、未派发、无代码。

Container & model: M, mode:subagent, model: TIER_DEFAULT. Sized M rather than S: the doc edit is mechanical but the pin rewrite is a design judgement (what the pin guards after the defect is repaired), and per 〈派发〉 an S-sized card whose judgement lives in design rather than in the gates takes M treatment. ⚠️ dispatch-gates.mjs does not exist in objectui — gate families derived by hand and declared as such.
Clause-②: no
Thread-read: 5611331743
Serial constraints cleared: PR #8865 (claude/kanban-gantt-family-retirement, ready, another lane) also edits README.md — measured: its only README hunk is the kanban fence ("type": "kanban" → "type": "object-kanban"), a different region from the #### Basic Usage grid fence. Same-file ordinary concurrency; merge queue arbitrates, ⛔ no manual ordering. It does not touch schema-rendering.md, schema-playground.md, or the 8310 pin (its single packages/components file is renderers/complex/README-KANBAN.md). PR #8895 (this seat's other in-flight card) is confined to packages/types + scripts/check-doc-example-types.mjs — disjoint. No other in-flight claim touches this surface.

Ruling — direction, and why this is NOT a decision-box card

The card body ends with "## The decision, not made here" and lists three options. The triage verdict on this card (comment 5611331743) already closed that, and this seat adopts it rather than re-opening it:

Options 2 and 3 (make grid read items as an alias / declare items on GridSchema) are the lenient-fallback shape coding standard #0.1 (contract-first) forbids by name, and each would mint a second child-key dialect on one node. The card says so itself.
⇒ Option 1 — repair the three teaching surfaces to children — is the only surviving route. It is a floor already set by an existing standard, not a three-way choice.

Under 〈升级与决策〉 this sits squarely in the 具名不升级类: 「纯文档措辞更正(无契约声明改动)」 and 「恢复不变量」. The renderer and GridSchema are correct today; only the docs are wrong. ⛔ No maintainer decision is owed, and none is requested.

Premise re-measured this fire — the blocking constraint has CLEARED

The triage comment states the card ⛔ must not run in parallel with PR #8914 (card #8310), whose render pin deliberately transcribes the flagship example with items so this defect cannot hide inside a green.

Measured against origin/main aeaa0f6: PR #8914 is MERGED (2026-09-10T03:11:39Z). ⇒ the ordering constraint is discharged, and this card is dispatchable now. Verified the pin landed and still carries the deliberate spelling: packages/components/src/__tests__/page-body-single-node-8310.test.tsx:63 reads items: [, with :74 reading children: flagshipGridAsAuthored.items. Lit control on the same probe: 14 body hits in that file, so the readings are real and not a broken grep.

Three teaching surfaces on origin/main, items hits: README.md 1 · content/docs/guide/schema-rendering.md 4 · content/docs/guide/schema-playground.md 1.

裁定:交付席上报的分叉取 option A —— 并记下本席自己的裁定被推翻

派发席 domain:ui @ objectui,session_01MPaVWWMuWeT5LgB1qoXjVB(os-steve),2026-09-10T09:0xZ。PR #8951,head ac0d3d8,base main aeaa0f6,draft。

⭐ 先记我自己的错,因为它是本轮最有价值的读数

我的派发令 ZONE 1 第 4 条写了一句断言:

修好 README 会让那条 pin 变红,而且它该红。

实测为假。 交付席测到:本 PR 之前,page-body-single-node-8310.test.tsx 只持有一份本地转写,从不读 README.md,所以没有任何东西把它绑到落地页的字节上;而 types 侧那条 pin 确实读 README,但它的扫描腿断言的是 body 元数与 page/grid/statistic 形状,从不断言子键。⇒ 文档改完后两条 pin 都是绿的。

⛔ 这不是"基线移动"能开脱的:那是我的读数被我写成了裁定,正是本车道两份交接文档(objectui#7089 §6、objectui#7233 §1)点名的席位常发缺陷 —— 「treating "I read a result" as "I measured"」。它被逮住,是因为派发令按三分区写、并明写「a clean stop on a falsified premise is a full success」。⇒ 这条纪律当轮第二次付回报(第一次在 objectui#8885)。

交付席的处置是对的:指令照执行(转写改为修好后的原文、守卫散文重写),并补上一条 README 扫描腿使这句断言从此为真,且用 Leg A 证明该腿能红(把 README 还原为 items,该腿 expected … to contain 'children: [' 失败)。

裁定:option A —— 扩一个文件,本 PR 内修掉

packages/types/src/__tests__/page-body-arity-8310.test.ts 纳入本卡文件面::92 的 items 转写、称其为「README 旗舰例交给 body 的 grid 节点」的 docblock、以及把 items 拼写描述为在案未修缺陷的头段 —— 三处都因本 PR 而变假。

理由(可被复核,不是权威):本 PR 正是把它们变假的那一个。 带着一条已知为假且无具名承接者的注释落地,就是本仓一直在打的 declared≠enforced 腐化;而「什么都不会红」恰恰是它会安静烂掉的原因。C(单开卡)对一条不红的陈旧注释不成比例。按 SKILL.md 〈升级与决策〉,这属具名不升级类(纯文档措辞更正,无契约声明改动 + 恢复不变量)⇒ 席位裁量,⛔ 不上呈、⛔ 不新开卡。

串行约束已由本席先验再裁,⛔ 未假设:无在飞认领持有该文件。PR #8895 触及 packages/types/src/__tests__/ 恰好三个文件(imported-defaults-8317 / object-chart-undeclared-keys-8885 / zod-mirror-parity),page-body-arity-8310.test.ts 不在其中;PR #8903 局限于 scripts/。

补丁轮已续派原交付席(⛔ 不重开新 dev)。边界:只修陈旧真值,⛔ 不重构该 pin、⛔ 不改它断言什么(它的主题是 body 元数,本卡不碰)、⛔ 不往它加腿;grid 渲染器与 GridSchema 保持不动。

复核清单(本轮已核部分,⛔ 对 GitHub 不对自述)

项	读数
PR 形态	`draft: true` · base `main` · 首行 `Fixes #8912` ✅ —— 与 #8885 不同,本卡无 Part 2,闭合关键字正确
范围	5 文件,`+139/−50`,与申报文件面一致
changeset	空 frontmatter ✅ —— docs + test,`apps/site` 是 `"private": true`,`content/docs/**` 不发布任何东西;`patch` 会谎称一个已发布包动了
验收工具	渲染输出,非编译 ✅。Leg B 把 pin 转写还原为 `items` ⇒ 两条渲染断言红(`expected '' to contain 'Total Users'`),而同一次运行里 grid 元素断言仍绿 —— 这就是那条点亮的正控:破的构建上 `page` 与 `grid` 照样画得出来
门禁判别力	交付席主动申报 `check:doc-types` 与 `check:doc-examples` 在本类上无判别力,并说明其绿只证明没弄坏别的 ⛔ 不证明缺陷已修 —— 这正是本卡要的读法
逐条判定	6 处 `items` 命中逐个判,3 处是缺陷、3 处是散文与一个数据作用域表达式变量 ⇒ ⛔ 未批量替换
定级触发器	p1 与 p3 都实测且都不触发(无 `create-*` 模板内联旗舰例;三处 fence 均可达)⇒ `priority:p2` 维持

⇒ 补丁轮后再出 ACCEPT;⛔ 本轮不翻 ready、不入队。

⚠️ 上报维护者的一条冲突(交付席申报,未自行消解 —— 正确)

agent 契约要求 commit trailer 不含模型标识,而会话侧模板提供了一条含模型名的 Co-Authored-By。交付席按契约取无模型形态并申报而非静默取舍。本席确认该取舍成立:环境规则是点名仓库工件的明文禁令(⛔ commit message / PR 标题正文 / 代码注释 / 任何推入仓库的工件不得含模型标识),禁令高于模板。⛔ 无门禁读这一项,故记录在此而非埋掉。

NOTE the honest cost: re-running check:doc-snippets / check:doc-examples right now would report exit 2 = PRECONDITION NOT MET, because the worktree teardown after round 1 removed the built dist/ those gates need. That is why they are labelled CARRIED FORWARD and NOT re-reported as fresh greens. CI builds and runs them on the real head.",

Flagged rather than absorbed silently.",
"The docblock the ruling named ('the grid node the README's flagship example hands to body') became TRUE again the moment the key was renamed. It was still rewritten, to name the children spelling and the card, so a future reader meets the reason at the literal instead of having to reconstruct it.",
"origin/main moved during the round (aeaa0f6 -> 8011852) and was merged into the branch with git merge, no rebase and no force-push, before editing. Verified by name that the range touches no file this PR owns: it moved 3 files, all under apps/site.",

派发席 domain:ui @ objectui,session_01MPaVWWMuWeT5LgB1qoXjVB,2026-09-10T09:2xZ,对 head e1bf5c9。⛔ 对 GitHub 核验,不对终报自述核验。

复核清单

项	读数
PR 形态	`draft: true`(核验后由本席翻)· base `main` · 首行 `Fixes #8912` ✅ —— 本卡无 Part 2,闭合关键字正确(与 #8885 的 `Part of` 形成对照)
范围	6 文件,`+154/−58`,含补丁轮扩入的一个文件
changeset	空 frontmatter ✅ —— `apps/site` 是 `"private": true`,`content/docs/**` 不发布;`patch` 会谎称一个已发布包动了
门禁	33 个 check 全部 completed:30 success,3 按设计 skipped,⛔ 零红、零 pending
路径面	NOT GOVERNED,三条独立腿(见下)
Clause-②	`no` —— docs + tests,无已发布运行时面移动

门禁 job 级结论(⛔ 不读聚合):Type Check 09:17:12Z success · Test (shard 1..4/4) 全 success · Governed Surface Queue Guard success · Doc Snippet Type Check / Doc Component Type Check success · Live E2E (informational) success。

⚠️ get_status 只返回 commit status(Vercel 一条),⛔ 不含 check run —— 这正是本仓「放行认 job 结论、⛔ 不认聚合读数」那条规则的具体理由,记在此。

路径面三条腿

① 本席按路径自核 6 个文件,无一命中受管五面(docs/adr/** · .claude/** · skills/** · AGENTS.md · CLAUDE.md);② CI 的 Governed Surface Queue Guard = success;③ 点亮对照:本席本地跑 check-governed-queue-guard --test AGENTS.md,返回 GOVERNED ⇒ 该守卫确有判别力,那个 NOT GOVERNED 是读数而非坏探针。

⭐ 补丁轮的两条,值得记进车道

① 交付席找到的是四处,不是本席裁的三处。 第四处是 README 扫描辅助函数的 brace-scanner 注释,提到嵌套 items[]。同类、同文件、同一个词的修复,落在裁定「陈旧真值修复」的remit 内 —— 申报而非静默吸收,这是对的。

② 「pin 没被重构」是被证明的,不是被声明的。 该文件 28 条 it( / describe( / expect( 行逐字节相同,且按文本比对而非按行号(散文编辑位移了行号,按行号比会给出假差异)。注释行之外整个 diff 只有两块:一个 docblock 开头由单行改为块,以及 items: [ → children: [。

③ 「type-check 覆盖了那条 pin」这个未测陷阱被主动关掉。 交付席没有假设,而是数了 tsc -p tsconfig.test.json --listFiles:该 pin 命中 1,正控 packages/types/src/layout.ts 1,负控(一个 components 测试)0 ⇒ 编译期那条腿是真被执行的,不是只被 glob 到。

⚠️ 申报的门禁「沿用」,本席接受,理由记明

四个 doc 门与 components 全量套件本轮未重跑,交付席申报而非隐瞒,并给了理由:补丁轮只动了一个 packages/types/src/__tests__/ 下的测试文件,不是文档面、不进任何包的构建产物;合入的 origin/main 区间只碰了 apps/site。⭐ 更诚实的一点:它指出现在重跑反而会得到 exit 2 = PRECONDITION NOT MET(轮一的 worktree 拆除带走了那些门需要的 dist/),所以标成沿用优于报一个新的假绿。CI 在真实 head 上跑了它们,全绿 ⇒ 沿用被 CI 覆盖,接受。

落地

落地核验 —— 按内容、四条腿,⛔ 不按 sha

在 origin/main(现为 3431bed64)上,同一组探针:

腿	合并前	现在
主体+ `README.md` 的 `children: [`	0	1
主体− `README.md` 的 `items: [`	1	0
正控 `README.md` 的 `statistic`	7	7
负控 `zzzNotInReadme`	0	0

⭐ 两个主体腿反向同时移动,而正控不动、负控仍为 0 ⇒ 这是真实的状态转移,不是探针漂了。

补丁轮那一半也一并核了:packages/types/src/__tests__/page-body-arity-8310.test.ts 的 items: [ 在 main 上现为 0 ⇒ option A 的陈旧真值修复确实随同落地,⛔ 没有被落下。

半状态已在本笔清掉

GitHub 由 Fixes #8912 自动关卡,但自动关闭不摘 pm:*:本卡关闭后仍挂着 pm:dispatched 与 assignee。按〈状态模型〉「关闭即在同一笔摘掉 pm:* 状态标;domain:* 与类型标签留下,归属不是状态」已清:pm:dispatched 摘除、assignee 清空;bug / documentation / priority:p2 / domain:ui 保留。

⚠️ finding 保留未动:本卡已定级 priority:p2,按惯例 finding 应在首次定级时离标 —— 但定级与 finding 的生命周期是分诊席的产出,⛔ 执行席不代摘。记为分诊缺口,与 objectui#8853 缺 priority:* 是同一类。

本卡实际交付的东西

三处教学面(含 npm / GitHub 落地页的旗舰示例)的 grid 子键由 items 改为 children —— 此前照抄任何一处的读者得到的是一个空 grid,而没有任何东西拒绝它(BaseSchema 是 .passthrough() 且带索引签名,所以它通过校验、通过类型检查、骑上节点、什么都不画)。

⭐ 并且验收工具从头到尾是渲染输出,不是编译:check:doc-types 与 check:doc-examples 在这一类上按设计就是绿的,交付席主动申报了这一点并把它们的绿标为「只证明没弄坏别的」。消融 Leg B 把 pin 的转写还原为 items,两条渲染断言变红(expected '' to contain 'Total Users'),而同一次运行里 grid 元素断言仍绿 —— 那就是点亮的正控:破的构建上 page 与 grid 照样画得出来。

⚠️ 一条给后继的账:本席在派发令里断言「修好 README 会让 objectui#8310 那条 pin 变红」。实测为假 —— 那条 pin 当时只有本地转写、从不读 README.md。交付席照旧执行指令,并补了一条 README 扫描腿使这句话从此为真,Leg A 证明该腿能红。⇒ 现在 README 若回退到 items,是真的会有东西红。
