finding(docs): 7 more ${…} sites on keys with no carriage row, in 3 pages no card covers — measured by the objectui#7851 census

[claude]

Measured by the census that objectui#7851 landed (PR objectui#7868), on 59df1dab2. Filed rather than repaired: objectui#7851's ruling is that the census is the deliverable and ⛔ it does not repair other pages' sites. Recording, not claiming — grading and domain:* are the triage seat's.

The measurement

Read from the artifact, never from prose: expressionBindableTextKeysFor out of the built @objectstack/spec@17.2.0 dist/ui/index.mjs, the same lookup SchemaRenderer.tsx:1139 consumes. SchemaRenderer evaluates exactly four channels — content, the carriage keys for the node's own type, the properties and props bags — plus the eight condition keys. An expression written anywhere else reaches the renderer as the characters the author typed.

Corpus-wide: 204 json/jsonc fences, 204 parsed, 0 unparsed, 17 uncarried sites in 5 pages. Of those 17, 8 belong to objectui#7418 (guide/expressions.md, PR objectui#7847) and 1 to objectui#7680 (schema-rendering.md's chart.data). The 7 below belong to no open card.

The seven sites

page	line	node	key	carriage rows for that type
content/docs/guide/schema-rendering.md	186	badge	text	none
content/docs/guide/schema-rendering.md	187	badge	variant	none
content/docs/guide/schema-rendering.md	207	alert	variant	none
content/docs/guide/schema-rendering.md	416	alert	message	none
content/docs/guide/architecture.md	257	badge	text	none
content/docs/guide/architecture.md	258	badge	variant	none
content/docs/guide/layout.md	511	page	title	none

Line numbers are as of 59df1dab2 and will drift; locate by content.

Two of them are worse than "the expression does not evaluate"

PR objectui#7847 measured both through the real production renderers while repairing the same shapes one page over, so this is quoted rather than re-derived:

• text is not a BadgeSchema key at all. BadgeSchema declares label / variant / icon / children, and renderers/data-display/badge.tsx renders schema.label. So "text": "${…}" on a badge renders an empty badge, with text=${…} leaking as a DOM attribute. Both badge.text rows above are that, not merely an unevaluated expression.
• success / warning / info are not badge variants. The closed set is default / secondary / destructive / outline. Both badge.variant rows above author one of the invalid three. (⚠️ Not asserted for alert: that component's variant set was not measured here.)

The ruling that already applies

The maintainer's 2026-09-01 ruling on objectui#7115 chose fork (B): non-text types get no new carriage rows, and the docs stop authoring ${…} in keys that have none — 「文档教现实」. ⛔ Adding carriage rows for badge.text, alert.message or page.title is fork (A) and was rejected; that widens an authoring surface and would be a maintainer decision, not a docs fix.

PR objectui#7847 is the worked precedent for how each site is decided — per passage, not one blanket rule: a passage demonstrating binding moves onto a channel that carries (a text node's content, evaluated on every type; or a real carriage key on the same node; or the properties bag), and a passage where the non-carrying component is the subject becomes a literal plus prose naming the missing row.

⚠️ Worth reading before acting: schema-rendering.md's two hits sit under headings named "Conditional Expressions" and "Complex Logic", so those passages are demonstrating binding and cannot simply be de-expressed without teaching something else.

Considered and deliberately NOT claimed

content/docs/api/schema-reference.md:612 authors "condition": "${data.items.length > 0}" inside the ActionSchema example. The census reports it, and it is recorded here so the next reader does not have to re-derive that it was looked at: type: "action" is the action vocabulary, not an SDUI component node, and condition is evaluated by the action runner's own gate rather than by SchemaRenderer's node channels. It is not part of this finding. (check:doc-types' header measured at least seven vocabularies in this corpus that all spell the key type; the census inherits that gate's ruling that a global key-path discriminator does not converge, and prints "a hit is a candidate, not a verdict" under every findings list for exactly this reason.)

How to re-measure

node scripts/check-doc-expression-carriage.mjs

Report-only: it prints the census and exits 0. It also prints its own blind spot in three directions — parsed/unparsed per fence language, and whether any fence outside json/jsonc would have parsed as a JSON document holding a typed node — so the "7 sites" above is a bounded number rather than "7 is what I happened to find".

Related, not duplicates: objectui#7418 (guide/expressions.md, in flight as PR objectui#7847), objectui#7680 (the chart.data site on one of these same pages), objectui#7440 and objectui#7444 (the read-back half of the class, which this census does not answer), objectui#7851 (the census itself).

⚠️⚠️ ① 先测一件事，它决定你的文件面：#7868 的钉子对语料计数敏不敏感？

PR #7868（卡 #7851）刚刚落地，它带着 scripts/__tests__/check-doc-expression-carriage.test.ts（28 个用例）。你修掉 7 个站点会把普查的头条数从 17 移到 10。

⛔ 先量，再动手：那个钉子是按 fixture 断言的，还是对活语料计数断言的？

• 若不敏感 ⇒ 文件面就是三个文档页，别碰 scripts/。
• 若敏感 ⇒ 那一行的更新属于同一次改动（否则你会明知故犯地发一条红 pin），并且必须写清理由：不是「把数字对齐」，而是「这 7 个站点被修复，所以总体真的从 17 变成 10」。⚠️ 顺便报出 gate 在你修完之后的完整新普查行。

⭐ 这条我特意放在最前面：本席在 #7444 上刚批准过一次同形的扩面（layout-dom-leak-5574 的 NODE_CENSUS 162→159），那次的教训是留着不改就是发一条已知的红 pin。

② 修法：逐处按它在教什么来修，⛔ 不要一条规则刷过去

#7847（PR，已落地）是工作样板，请读它。 它把 6 个站点分成两类处理：

• 在演示绑定的 ⇒ 继续演示（挪到 text/content 这类无类型门的键，或挪到同节点上真有 carriage 行的键）；
• 做不到的，因为那个不携带的组件本身就是主题（讲 badge、讲 card.className）⇒ 改成字面量 加一段散文点明缺哪一行、可用的替代是什么，与 finding(docs/gate): the root README's flagship dashboard example teaches stat-card, which nothing registers — and the root README is outside every doc gate's scan surface #7115 重写 progress / input 的姿态一致。

你的 7 处里，badge 那 4 处（schema-rendering ×2、architecture ×2）大概率落在第二类，alert 与 page.title 需要你自己判断。⛔ 但这只是本席的预判，以你的测量为准。

⚠️ ③ 有两处「比表达式不生效更糟」，卡面已点出，请自己复核

#7847 的席位在真实生产渲染器上实测过：

• badge.text 根本不是 BadgeSchema 的键 —— badge 的文字是 label；旧写法渲染出一个空 badge，text=${status} 作为 DOM 属性泄漏，并触发本仓 "Unevaluated expression reached the DOM" 诊断；
• success / warning / info 不是 badge 的 variant —— 闭合集是 default / secondary / destructive / outline。

⇒ ⭐ 所以这几处不只是表达式没被求值，是示例本身就是坏的。⛔ 只把 ${…} 换成字面量而留着 text 和越界 variant，等于把一个坏示例改成另一个坏示例。⚠️ 到当前 main 上自己复核这两条，⛔ 不要采信本裁定（本席这一轮已经三次因为传递上游结论句而出错）。

④ 行号会漂，按内容定位

卡面的行号测于 59df1dab2；此后 #7847 / #7859 / #7868 / #7875 等多张文档卡已落地。⛔ 不要按行号跳，按内容找，并把你在当前 main 上找到的实际位置写进 PR。

⑤ 携带面自己重读，⛔ 不要抄卡面那张表

卡面的「carriage rows for that type = none」读自已构建的 @objectstack/spec@17.2.0 dist/ui/index.mjs 的 expressionBindableTextKeysFor（SchemaRenderer.tsx:1139 真正消费的那张查找表）。从制品自己重读一遍并贴出读数 —— #7847 的席位这么做了，而且和卡面对上了；你也要有自己的读数。

⑥ 交付证据

修完之后跑一次 #7868 的普查 gate，把新的完整普查行贴进 PR。预期：17 → 10（剩下的是 #7418 已认领但刻意未修的 2 个 list.items、#7680 的 chart.data，加上 api/schema-reference.md:612 那个 ActionSchema 站点——⭐ 后者是「考虑过、明确不认领」，⛔ 不要顺手修它，它属于 action 词汇表，由 action runner 自己的门管）。

⚠️ 若新数不是 10，说明有人对语料做了别的改动，或本席对归属的理解有误 —— 报回，不要自己调和。

边界

• ⛔ 不动 content/docs/guide/expressions.md（finding(docs): guide/expressions.md still authors ${…} in 6 more keys with no carriage row — badge.text / badge.variant / card.className / card.body, beyond the two the 2026-09-01 ruling named #7418 已修，卡已关）。
• ⛔ 不动 schema-rendering.md 里 finding(docs/guide): schema-rendering.md teaches a chart node binding node-level data to a ${...} expression — not evaluated (the #6665 shape), and a parse refusal since #7113 #7680 的 chart.data 站点。
• ⛔ 不动 api/schema-reference.md。
• ⛔ 不改 scripts/check-doc-expression-carriage.mjs 本体的判据或扫描总体（只在第 ① 条成立时改它的测试里的那个数）。
• changeset： 跑 node scripts/check-changeset-presence.mjs，以判词为准并逐字贴出。⛔ 不许推理（今天检查器已四次否掉推理，含本席自己一次）。
• Clause-② = no：改文档示例，不加键、不动 zod、不动任何 gate 的判据或扫描总体。若判断错了，停下报回。

  "summary": "All seven uncarried-expression sites existed on current main exactly as the card described and are repaired, per passage, under the fork-B ruling. Measurement 1: #7868's pin is NOT corpus-count-sensitive — it asserts against inline CONTROL_FIXTURES and its one live-corpus case carries the comment 'Deliberately NOT asserted: how many findings there are'; its vacuity guards are fences>100 and nodes>100 (204 and 361 here). Confirmed by running: all 28 cases pass after the count moved, so scripts/ is untouched and no red pin is shipped. Six of the seven passages are teaching binding, so they move onto keys that genuinely carry (card.title/description, statistic.label/value/description, and a nested text node's content, which SchemaRenderer evaluates on every type); layout.md's page.title is the incidental one and becomes a literal plus prose. REPORT-BACK on measurement 6: the census reads 11 -> 4, not 17 -> 10. The 17 was measured on 59df1dab2 BEFORE PR #7847 landed; on this branch's base 655afabf2 the census already read 11, because #7847 repaired 6 of expressions.md's 8 sites. Removing this card's 7 lands on 4, which is exactly the remainder the dispatch enumerated (2 list.items + chart.data + the ActionSchema site). Attribution is correct and the corpus is intact; only the starting number was stale. Nothing was adjusted to make the arithmetic work — no count is pinned anywhere in the repo. Also extended the card's claim set: alert.message is not an AlertSchema key either (the alert's text keys are title and description), and AlertSchema.variant is the closed set default|destructive, so the old sites' info/warning/success/error were all off-enum — the card had left alert's variant set explicitly unmeasured.",

Real-renderer verification: a throwaway harness parsed each repaired fence OUT of the shipped page and rendered it through the production renderers with PredicateScopeProvider + SchemaRendererProvider — 8/8 green (card renders Active / This record is in use.; the Complex Logic alert renders Welcome! and You are all caught up.; the Error States alert renders Upstream timed out; the statistic renders 12 and Above target; no ${ survives in any DOM), including three negative cases pinning the old shapes (empty badge with ${status} left on the DOM, badge.label rendering, alert.message leaving the description slot empty). ABLATION: committed first, then restored the pre-repair pages from 655afabf2 onto disk. Mutation confirmed ON DISK by grep counts (pre-repair badge.text 1/1, page.title 1, repaired statistic fence 0), not by an editor exit code; the script carried a trap on EXIT/INT/TERM restoring absolute paths from HEAD. Under mutation the same harness went 5 failed | 3 passed — the five repaired-site cases fail, the three old-shape cases pass — so the instrument can fail. Restore leg proven byte-identical: git hash-object equals the HEAD blob for all three files (61257c6cb / 35c560cf5 / f54c7cd88), `git diff HEAD` empty, harness back to 8/8.

PM 裁定 · PR #7900 · 开放问 = A · ⚠️ 而且报回来的那个差是我算错了

⚠️ 先记我的账：17 → 10 是我的陈旧算术

我在派发令里写「预期 17 → 10」。实测是 11 → 4。你报回来而不是自己调和，这正是派发令第 ⑥ 条要求的行为。

差额已被你完整解释：17 测于 59df1dab2，那是 PR #7847 落地之前；到你这条分支的 base 655afabf2 时普查已经读 11，因为 #7847 修掉了 expressions.md 8 个站点里的 6 个。再减掉本卡的 7 个 ⇒ 4。

⚠️ 而且我在同一份派发令里明明写了「#7847 已落地」 —— 我记得那件事，却没把它算进那个数。⇒ 陈旧的不是事实，是我的算术。

逐项核对，归属完全对上：

59df1dab2 的 17：expressions.md 8 · schema-rendering.md 5 · architecture.md 2
                  · schema-reference.md 1 · layout.md 1
减 #7847 修掉的 6（expressions.md）              ⇒ 11
减 本卡的 7（schema-rendering 4 + architecture 2 + layout 1） ⇒ 4
剩下的 4 = expressions.md 的 2 个 list.items（#7418 刻意未认领）
         + schema-rendering.md 的 chart.data（#7680）
         + api/schema-reference.md 的 ActionSchema 站点（考虑过、明确不认领）

⇒ 与派发令自己列的那份四项余量清单，逐项相符。裁定 A：无需再做。 ⭐ 而且关键是——仓库里没有任何地方钉住过这个数，所以没有任何东西被「调和」过；你也明确说了没动任何 pin、判据或扫描总体。

---

✅ 测量 ① 的答案，正是我要的形状

#7868 的钉子对活语料计数不敏感，而且你给了机制而不只是结论：它断言的是内联的 CONTROL_FIXTURES，唯一那条活语料用例带着注释 "Deliberately NOT asserted: how many findings there are"，它的空转护栏是 fences>100 与 nodes>100（此处 204 / 361）。

并且你跑了它来确认：计数移动之后 28 个用例全过 ⇒ scripts/ 一行未动，⛔ 没有发出任何已知的红 pin。

⭐ 这是「先量再动手」的正确执行：结论是「不用改」，但那是测出来的，不是假设出来的。

⭐ 你扩展了卡片的断言集，而且补上了卡面明确未测的那一格

卡面把 alert 的 variant 集合留成了显式未测量。你测了：

• alert.message 也不是 AlertSchema 的键 —— alert 的文本键是 title 与 description；
• AlertSchema.variant 的闭合集是 default | destructive ⇒ 旧站点上的 info / warning / success / error 全部越界。

⇒ ⭐ 与 #7847 在 badge 上发现的是同一个形状（badge.text 根本不是键、success/warning/info 不是 variant）。这一族文档缺陷的真面目正在收敛：写的不是「表达式没生效」，是「这个键压根不存在，而且值也越界」。

⭐ 逐段选路，六比一

七处里六处在教绑定 ⇒ 挪到真有 carriage 的键（card.title/description、statistic.label/value/description，以及一个嵌套 text 节点的 content——SchemaRenderer 对每种类型都求值它）；layout.md 的 page.title 是顺带的那一处 ⇒ 字面量加散文。⛔ 没有一条规则刷过去。

⭐ 真渲染器验证 + 可失败的消融

一次性 harness 把每个修好的 fence 从已发布的页面里解析出来，配 PredicateScopeProvider + SchemaRendererProvider 过生产渲染器：8/8 绿，且任何 DOM 里都不残留 ${；其中三条是阴性用例，钉住旧写法（空 badge 把 ${status} 留在 DOM 上、badge.label 渲染、alert.message 让 description 槽为空）。

消融：把修复前的三个页面恢复到磁盘（磁盘上先用 grep 计数证明落盘，⛔ 不用编辑器退出码），harness 变成 5 failed | 3 passed —— 五个修复站点用例失败、三个旧写法用例通过 ⇒ 仪器会失败。恢复腿由 git hash-object 对三个文件逐一等于 HEAD blob 证明（61257c6cb / 35c560cf5 / f54c7cd88）。

派生 #7898，已上板

九个 JSON fence 写了 schema 未声明的 button 键：六处 button.text（ButtonSchema 声明的是 label，渲染器读 schema.label）+ 三处顶层 onClick（handlerKeyRefusal 的 runtime-slot，按名拒绝）。

⚠️ 它们都持有字面量，所以携带面普查看不见，而 check:doc-types 只判 type 字面量 ⇒ ⭐ 又一个「掉在所有仪器之间」的实例——与 #7896（package README 的 type 字面量无人判）是同一族几何。

⭐ 而 quick-start.md:149 的 onClick 被记为 measured-and-NOT-a-defect（它在 events 包里，是正确的方言）—— 把「考虑过、明确不是缺陷」写下来，下一个读者就不必重新推导。

落地路线： Clause-② no，不欠 changeset（判词逐字），CI 终态后由本席跑三条前检并出队。
