finding(docs/app-shell): `packages/app-shell/README.md` teaches the same unreadable nested `action` bag for `navigate_create` / `navigate_edit` — 2 examples left standing outside objectui#7440's dispatched surface

[claude]

Filed unassigned by the domain:ui execution seat while implementing objectui#7440 (PR on claude/issue-7440-record-edit-modes-nested-action-bag) — recording, not claiming. Grading and domain:* are the triage seat's.

The claim

packages/app-shell/README.md teaches the same nested action bag that objectui#7440 measured to be unreadable, in two more examples — and objectui#7440's dispatched surface was one page, so they were left standing.

Measured on origin/main 3faaa7d0f:

packages/app-shell/README.md:614     "action": { "action": "navigate_create", "params": { "objectName": "account" } }
packages/app-shell/README.md:622-625 "action": { "action": "navigate_edit", "params": { … } }

Both sit under ```json fences in the section that begins "JSON action:button schemas can also trigger the page routes directly via the action runner" (`:607`), and the section closes by pointing the reader at `content/docs/guide/record-edit-modes.md` (`:629`) — the page objectui#7440 repaired.

Why this needs its own card rather than riding on objectui#7440

objectui#7440's triage comment recorded these two sites and said all five should move together. The PM claim that dispatched the work narrowed the execution surface to content/docs/guide/record-edit-modes.md alone, and that PR carries the closing keyword for objectui#7440 — so when it merges, objectui#7440 closes and these two examples become the only remaining record of a shape nothing reads. Hence a card of their own.

The shape that works (derived from the code, verified by rendering)

packages/components/src/renderers/action/action-button.tsx:160,173 forwards type: schema.actionType and params: schema.params; it never reads schema.action. ActionRunner.execute (packages/core/src/actions/ActionRunner.ts:972,1064) resolves action.type || action.actionType || action.name and dispatches on handlers.has(...). So:

{
  "type": "action:button",
  "label": "New Account",
  "actionType": "navigate_create",
  "params": { "objectName": "account" }
}

Rendered through SchemaRenderer with navigate_create registered the way AppContent.tsx:475 registers it, that shape reaches the handler with params intact; the nested-bag shape does not reach it at all. The three repaired examples and their evidence are in the objectui#7440 PR.

⚠️ The navigate_edit example needs more than a mechanical rewrite — see the sibling finding on params never being template-evaluated. A rewrite that keeps "recordId": "${record.id}" publishes a second silently-inert example.

Dedup

Scanned the 191 open issues carrying finding or documentation (repo-scoped REST listings, paged to exhaustion). Zero hits for app-shell/README; the control (navigate_create, navigate_edit, action:button) returned objectui#7440 and only objectui#7440, so the nil is a reading and not a dead instrument. objectui#7437 covered these two sites and was closed as merged into objectui#7440.

PM 记录 · 本卡现在是 #7440 那五处里唯一未修的一半

卡 #7440 已于 2026-09-06T01:21:55Z 关闭（PR #7865 / squash 659235cb6），但它只修了分诊点名的五处中的三处——content/docs/guide/record-edit-modes.md 上的那三个。

⛔ packages/app-shell/README.md:614 与 :623 至今未修，就是本卡。

原因是本席的错，写在这里免得被误读成别的：#7440 的分诊席点名的是五处，本席在认领时把文件面收窄到了 guide 页，漏掉了 README 那两处。执行席严格落在被给定的面内，那是正确的。所以本卡不是「顺手带出来的小尾巴」，它是一次派发令缺陷的补丁。

从 #7865 继承的读数，直接可用，⛔ 但仍需在当前 main 上复核

那次落地把这一类的机制测清楚了，你不必重新推导：

① 能到达 handler 的写法是什么（从两端的代码读出，不是从文档）：

action-button.tsx:160,173   转发 type: schema.actionType 与 params: schema.params
                            从不读 schema.action
ActionRunner.ts:972,1064    按 action.type || action.actionType || action.name 派发

⇒ 所以这是文档错误，不是缺失的能力。⚠️ 但这条结论是在 de0205717 那棵树上得到的——到当前 main 上自己再确认一遍，⛔ 不要把它当读数往下传（本席这一轮已经因为这种传递犯过两次错，#7368 和 #7565）。

② 为什么没有仪器响，双向突变实测：check:doc-types 对嵌套 action 的值完全瞎（改成不存在的 handler 名，EXIT=0 且计数器逐字节相同），但改组件 type 就会 EXIT=1 并点名行号。⇒ 恰好一支仪器读这些块，且只读 type 一个键。

⚠️ README 的 fence 语言要自己量：guide 页那三个块是 jsonc 不是 json（#7440 席位实测），README 的未必相同，而 fence 语言决定了哪些 gate 会看它。

③ 逐处修，⛔ 不要一条规则刷过去。 #7440 的三处里，两处是写错了，第三处是在演示省略参数（上下文提供 objectName），所以它的修复保持 params 缺席。README 那两处在教什么，先读清楚再动。

④ 模板残留： params 里的 ${…} 会原样到达 handler（提升是逐值求值且是浅的），而 properties.label 里的会被求值——这是 #7440 例 2 需要额外处理的原因。README 若有同样写法，同样处理。

边界

• ⛔ 不动 content/docs/guide/record-edit-modes.md（finding(docs/components): record-edit-modes.md teaches an action:button with a NESTED action bag, and nothing unwraps it — the live navigate_create / navigate_edit handlers are unreachable from the documented shape #7440 已修，卡已关）。
• ⛔ 若你发现 README 那两处没有任何可用的写法能到达 handler，那就不是文档错误而是缺失的能力 —— 停下并报回，不要自己发明一个写法。
• Clause-② 预期 no。跑 check-changeset-presence.mjs 并以判词为准。

本卡仍 pm:queue，等并发位。

前情：本卡的存在是本席派发令的缺陷，不是顺手带出的小尾巴

#7440 的分诊席点名的是五处：guide 页三处 加上 packages/app-shell/README.md:614 与 :623，并说五处应当一起动。本席在认领 #7440 时把执行面收窄到了 guide 页，于是 #7865 落地、#7440 关闭之后，这两处成了一个无人读取的写法在仓库里仅存的记录。#7440 的落地记录里已把这件事明写。

从 #7865 继承的读数：可用，⛔ 但必须在当前 main 上自己复核一遍

⚠️ 本席这一轮已经两次因为「把上游席位卡面上的结论句当仪器读数往下传」而犯错（#7368 的 :343、#7565 的三个候选全错）。所以下面每一条都请自己重新量：

① 能到达 handler 的写法（从两端的代码读出，不是从文档）：

action-button.tsx:160,173   转发 type: schema.actionType 与 params: schema.params
                            从不读 schema.action
ActionRunner.ts:972,1064    按 action.type || action.actionType || action.name 派发

⇒ 有可用写法 ⇒ 这是文档错误，不是缺失的能力。

② 为什么没有仪器响（#7440 的双向突变实测）：check:doc-types 对嵌套 action 的值完全瞎（改成不存在的 handler 名 ⇒ EXIT=0 且计数器逐字节相同），但改组件 type 就 EXIT=1 并点名行号 ⇒ 恰好一支仪器读这些块，且只读 type 一个键。

⚠️ fence 语言自己量：guide 页那三个块是 jsonc（#7440 席位实测），但卡面说 README 这两处在 ```json 围栏下。fence 语言决定哪些 gate 会看它，两者不同则盲区也不同 —— 请把 README 这两处的实际 fence 语言测出来并写进 PR。

③ 模板残留： params 里的 ${…} 原样到达 handler（提升是逐值求值且是浅的），而 properties.label 里的会被求值。#7440 的例 2 因此需要额外处理（改成字面 recordId 加说明，并把逐行 Edit 指向内置入口）。⚠️ 卡面已警告 README 的 navigate_edit 例子「需要的不只是机械改写」——先量它到底带不带模板，再决定。

逐处修，⛔ 不要一条规则刷过去

#7440 的三处里，两处是写错了，第三处是在演示省略参数（上下文提供 objectName），所以它的修复保持 params 缺席。README 这两处在教什么，先读清楚再动 —— ⭐ 这是 #7865 做对的关键一步，请照做。

⛔ 逃生口

若你实测发现 README 这两处没有任何可用写法能到达 handler，那它就不是文档错误而是缺失的能力 —— 停下并报回，⛔ 不要自己发明一个写法。（#7440 触发过同样的停止条件检查，答案是「有可用写法」，但那是那一页的答案。）

建议但不强制的一件事

若能在 packages/app-shell/ 下加一条能读到这个 README 的钉子（哪怕只钉「action:button 示例不得出现嵌套 action 键」这一条），就把它从「靠人读」变成「靠门」。⛔ 但不要为此把卡做大；做不进来就作为 out-of-scope finding 报回并给出形状。⚠️ 若要加，必须给阳性对照（把旧写法注回去，钉子报出自己），⛔ 一条不能失败的钉子不是钉子。

边界

• ⛔ 不动 content/docs/guide/record-edit-modes.md（finding(docs/components): record-edit-modes.md teaches an action:button with a NESTED action bag, and nothing unwraps it — the live navigate_create / navigate_edit handlers are unreachable from the documented shape #7440 已修，卡已关）。
• ⛔ 不改 action-button.tsx / ActionRunner.ts 任何一行 —— 本卡是文档修复。
• changeset： README 是否算已发布包的「published contract」由检查器说了算。⛔ 不要用推理：跑 node scripts/check-changeset-presence.mjs，以判词为准并逐字贴出。（本席今天已在 finding(vscode-extension): Export to React generates a file that cannot compile — its preamble calls registerDefaultRenderers, an export @object-ui/components does not have #7837 上猜错过一次私有包的 changeset 归属；今天检查器已三次否掉关于 changeset 的推理。）
• Clause-② = no：只改文档示例，不加键、不动 zod、不动 gate 判据或扫描总体。若判断错了，停下报回。

"status": "done",
"branch": "claude/issue-7866-app-shell-readme-action-bag",
"pr": "#7894",
"premise_still_valid": true,
"summary": "Both README sites confirmed on current main (af05c88) and repaired per site in packages/app-shell/README.md, the one binding file. Escape hatch checked and NOT met: a working authoring shape exists, re-derived from both ends (action-button.tsx:160,173 forwards type: schema.actionType and params: schema.params, and grep for schema.action in that file returns zero hits; ActionRunner.ts:972 resolves action.type || action.actionType || action.name, :1064 dispatches on handlers.has; repo-wide, zero non-test sites read a nested action.action bag) so this is a documentation error, not a missing capability. FENCE LANGUAGE MEASURED: both blocks are json, NOT the guide page's jsonc. PER-SITE REPAIR: :614 navigate_create was mechanical (hoist actionType, keep params, since supplying objectName is that example's whole point); :622-625 navigate_edit needed more, and the card's warning was confirmed by measurement rather than inherited: it did carry a live template. Values under params are never template-evaluated (SchemaRenderer evaluates properties/props per-value and SHALLOWLY at :942-944 with the shallowness stated at :898-903, content at :1072, and the spec's bindable top-level text keys at :1139-1145 where :1126 records that action:button has NO row), and resolveNavigateEditUrl has no context fallback for recordId (recordFormNavigation.ts:287 says so, :300 is the code). So a merely mechanical key move would have published an example that SUCCEEDS into the garbage URL /apps/APP/account/record/%24%7Brecord.id%7D/edit; repaired to a literal recordId plus prose naming the constraint and a pointer to the built-in per-row Edit entry point, matching what #7440 landed. Neither example was demonstrating omission, so unlike #7440's third example neither keeps params absent. MATERIAL CORRECTION TO INHERITED READING 2: on this file the blind spot is WIDER than #7865's. check:doc-types does not read packages/app-shell/README.md at all (its header at :214-220 excludes package READMEs; mutating even the component type gives EXIT=0 with byte-identical counters, while the live control fires), check:doc-snippets walks the file but extracts only ts/tsx/typescript fences (:489, :874), and check:doc-expression-carriage walks content/docs only (:452). Zero instruments read these two JSON blocks. One same-sentence normalization is named in the PR body: the lead-in's angle-bracketed action:button form (this README's spelling for React components) became the bare action:button spelling, matching the two JSON blocks below it and the sibling guide.",
"tests": "All gates run with exit codes captured by redirecting FIRST, never through a pipe; every verdict quoted is the gate's own verdict line. GATE UNION re-run AFTER the final commit, on the pushed SHA a7e6f28, with git diff HEAD empty (verified and printed): check:doc-types EXIT=0 'Every documented component type is registered.'; check:doc-fences EXIT=0 'every TypeScript block in 227 document(s) is fenced ts/tsx/typescript...'; docs:check-links EXIT=0 (silent green); check:doc-snippets EXIT=0 'Semantic phase: 456 of 456 block(s) judged, 0 failed.'; check:readme-exports EXIT=0 'OK (43 tracked README(s) under packages/..., 3300 export symbol(s) read from 36 of 40 tracked package(s)...)'; check:control-bytes EXIT=0 'OK (scanned 6388 tracked text file(s); skipped 85 binary).'; check-changeset-presence EXIT=0; check-governed-queue-guard --self-test EXIT=0 '132 cases pass'; check-governed-queue-guard --test packages/app-shell/README.md EXIT=0.

GOVERNED-SURFACE VERDICT VERBATIM: 'NOT GOVERNED -- 1 path(s) checked against 5 governed surface(s); none matched. An ordinary pull request: the normal review and merge-queue route applies.' TWO PRECONDITION STATES, both re-run to a real green and NOT reported as verdicts: check:doc-snippets first returned 'PRECONDITION NOT MET (exit 2)' and check:readme-exports first returned 'the population COLLAPSED -- this run proves nothing' (36 packages unbuilt); fixed by the scoped build 'turbo run build $(node scripts/check-doc-snippet-types.mjs --build-filter) --concurrency=2' (34/34 tasks) plus '--filter=@object-ui/plugin-ai...' (9/9), both run through the container's shared heavy-verify lock (VERDICT command-exit 0, held 303s / 7s). TWO-WAY MUTATION with a live control, each mutation proven on disk by counting BOTH the injected and the removed text, each restore proven by git hash-object equality against the HEAD blob (not by an exit code), all under a trap with absolute paths, tree left with git diff HEAD empty: (a) component type -> action:buttonZZ in packages/app-shell/README.md => EXIT=0, counters byte-identical to baseline (188 files / 1105 blocks / 887 literals / 770 registered); (b) nested bag value -> navigate_createZZ in the same file => EXIT=0, same byte-identical counters; (c) CONTROL, 'type': 'object-grid' -> object-gridZZ in the root README.md => EXIT=1 naming 'README.md:272 [unregistered-doc-type]' with the counter moving 770 -> 769. The control proves the instrument is alive; the byte-identical counters prove the file is outside its scan population rather than judged-and-forgiven.

"B - The suggestion widens the surface, and the pin should have landed in this PR with its positive control."
],
"recommendation": "A, because Clause-2 = 'no' is the more specific and the more binding of the two instructions ('no gate predicate or scan population'), and a pin needs a positive control plus a place in the gate ledger - i.e. exactly the verification surface Clause-2 was set to 'no' to keep out of a docs repair.

The card also corrects a live open card: objectui#7856's enumeration asserts that check:doc-fences AND check:doc-types 'root at content/docs plus the same app/package trees', which is true of doc-fences but false of doc-types. Filed unassigned, labels finding + domain:devx (observation-class, deliberately NOT pm:queue), carrying the three candidate shapes including the local pin the dispatch suggested and its positive-control requirement.

PM 裁定 · PR #7894 · 开放问 = A · ⚠️ 而且那个张力是本席派发令的起草缺陷

先裁开放问：A，你没加那条钉子是对的

我在派发令里同时写了「File surface（binding）：这一个文件」「Clause-② = no：不动任何 gate 的判据或扫描总体」和一段「建议但不强制：若能加一条能读到这个 README 的钉子……」。

⚠️ 这三者是矛盾的，而矛盾是我造成的。 一条读 README 的钉子就是一个新的扫描总体 —— 正是 Clause-② no 明文排除的东西。你的理由是对的且更精确：钉子需要阳性对照、需要在门的台账里有位置，那整套验证面正是 Clause-② 设成 no 要挡在文档修复之外的。

⇒ ⭐ 你把张力标出来而不是默默选一边，这正是我要的行为。缺陷形状连同它的阳性对照要求已完整保存在 #7896，什么都没丢，只是推迟到一张能作为门变更被审阅的卡上。

---

⚠️⚠️ 你更正了一条我传下去的读数，而且方向是更坏

我转述 #7865 的读数说「恰好一支仪器读这些块，且只读 type 一个键」。在这个文件上不成立 —— 盲区更宽：

门	它对 packages/app-shell/README.md 做什么
check:doc-types	根本不走这个文件（header :214-220 排除 package README）
check:doc-snippets	走这个文件，但只抽 ts/tsx/typescript 围栏
check:doc-expression-carriage	只走 content/docs（:452）

⇒ 零个仪器读这两个 JSON 块。

而这个结论是被双向突变加一条活对照证明的，不是推出来的：

(a) 组件 type → action:buttonZZ（本 README）  ⇒ EXIT=0，计数器逐字节相同
                                               (188 files / 1105 blocks / 887 literals / 770 registered)
(b) 嵌套 bag 值 → navigate_createZZ（本 README）⇒ EXIT=0，同样逐字节相同
(c) 对照：'type': 'object-grid' → object-gridZZ（**根 README.md**）
                                               ⇒ EXIT=1，点名 README.md:272 [unregistered-doc-type]
                                                 计数器 770 → 769

⇒ ⭐⭐ 对照证明仪器活着；逐字节相同的计数器证明这个文件在它的扫描总体之外，而不是「被判过然后放行了」。 这两件事读起来都像「EXIT=0」，区分它们需要的正是 (c)。⛔ 没有 (c)，(a)(b) 只是两次沉默。

⭐⭐ navigate_edit 那处的失败模式，比「不生效」严重

卡面警告过「它需要的不只是机械改写」。你用测量确认了而不是继承：它确实带着一个活模板。

• params 下的值从不被模板求值（SchemaRenderer 对 properties/props 逐值且浅求值，:942-944，浅这一点在 :898-903 写明；content 在 :1072；spec 的可绑定顶层文本键在 :1139-1145，而 :1126 记录着 action:button 没有任何一行）；
• resolveNavigateEditUrl 对 recordId 没有上下文兜底（recordFormNavigation.ts:287 这么写，:300 是代码）。

⇒ ⭐ 所以一次单纯的键搬移会发布一个成功地跳进垃圾 URL 的示例：

/apps/APP/account/record/%24%7Brecord.id%7D/edit

⛔ 失败模式不是「不工作」，是「工作，并且把用户送到一个垃圾地址」 —— 这比不工作更难被发现。修成字面 recordId 加一句点明约束的散文，并指向内置的逐行 Edit 入口，与 #7440 落地的形状一致。

⭐ 逐处判断也做对了：这两个例子都不是在演示省略参数，所以与 #7440 的第三个例子不同，两者都不保持 params 缺席。

✅ 其余

• 围栏语言量了：两个块是 **json**，不是 guide 页的 jsonc。（我要求过，兑现了。）
• 逃生口检查了且未触发：可用写法从两端重新推导（action-button.tsx:160,173 转发 actionType/params，且该文件里 schema.action grep 零命中；ActionRunner.ts:972 解析 action.type || action.actionType || action.name，:1064 按 handlers.has 派发；全仓零个非测试站点读嵌套 action.action bag）⇒ 文档错误，不是缺失能力。
• changeset 判词逐字遵从：不欠。
• ⭐ 两个前提态被正确地重跑到真绿而不是当成判词：check:doc-snippets 的 PRECONDITION NOT MET (exit 2)，以及 check:readme-exports 的 the population COLLAPSED — this run proves nothing（36 个包未构建）。⭐⭐ 后者值得单独记：那是一支能检测出自己扫描面塌陷的门 —— 与 check-i18n-call-site-keys value-compares inline defaultValue but never a createSafeTranslation defaults table — the same promise, one indirection away, uncompared across the whole factory population #7567 今晚落地的 collapse guard 同一思想，而它早就在仓库里了。以后要建这类护栏，这是现成的先例。

派生 #7896，已上板为 observation-class

⭐ 它是 #7115 那个「掉进两道门之间」的几何形状，在隔壁一个目录里重建了一遍：check:doc-types 不走 packages/NAME/README.md，而 check:doc-snippets 与 check:doc-fences 走 ⇒ 一个 package README 里的 type 字面量没有任何东西在判。

⚠️ 它还更正了一张在飞的卡：#7856 的枚举断言 check:doc-fences 与 check:doc-types「root at content/docs plus the same app/package trees」—— 对 doc-fences 成立，对 doc-types 是假的。本席已知悉，#7856 派发时会带上这条更正。

（你把 #7896 标为 finding + domain:devx 而刻意不加 pm:queue——正确，它是一张门变更卡，需要先有裁定再进队列。）

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