docs(app-shell): the README's flow draft teaches node type `action`, which `FlowNodeAction` does not contain and nothing in the flow canvas handles — a second re-classification out of the #8111 census

[baozhoutao]

Found while ruling the 25 candidate DOC_TYPE_EXEMPTIONS entries for objectui#8115 (the package-README census, PR #8111). Filed unlabelled and unassigned: grading and routing are the triage seat's. ⛔ Not repaired here — objectui#8115 forbids package README content edits.

Dedupe before filing: open issues carrying finding (154 rows, two pages) and documentation (31 rows) were pulled by repo-scoped REST and grepped locally for flow.?node, FlowNodeAction, app-shell/README and DOC_TYPE_EXEMPTIONS. Zero hits for this defect. Positive control in the same scan: objectui#7896 is present in the fetched set, so the reading is a reading.

The site

packages/app-shell/README.md:395, inside the "Visual flow canvas" jsonc block:

{ "id": "email", "type": "action", "label": "Send reminder" },

PR #8111's census tabled this site as one of four "flow-graph node kinds" and therefore as a candidate exemption. Three of the four are real. This one is not.

Why it is not a flow node kind — measured on c1ae1af0b

• FlowNodeAction, the canonical list of built-in node type ids, is declared in the objectstack sibling repo at packages/spec/src/automation/flow.zod.ts:27-51. Its 20 members include start, end and decision — the README's other three — and action is not among them.
• NODE_PALETTE, the add-node palette at packages/app-shell/src/views/metadata-admin/previews/flow-canvas-parts.tsx:333-355, offers 18 kinds. action is not one of them.
• Nothing in the flow canvas, layout, inspector or simulator branches on a node type of action. The case 'action': hits under previews/ are in AppNavCanvas.tsx and AppPreview.tsx, which are the app NAVIGATION item vocabulary (AppPreview.tsx:69 lists it beside object / dashboard / page / url / report), and FlowCanvas.tsx:993's pick('action') reads a config KEY named action, not a node type.
• The consequence is a loud rejection, not a silent nothing. flow.zod.ts:14-16 records that FlowNodeSchema.type is a validated string "checked against the live action registry at registerFlow() time, not frozen here". A reader who copies this draft gets it refused at registration.

Negative-reading control, same run: decision resolves in NODE_PALETTE at flow-canvas-parts.tsx:338 and in FlowCanvas.tsx:960, so the search does reach flow code and a zero for action is a measurement rather than a miss.

Why this matters for objectui#8115

The census's proposed exemption for this site would have read "flow-graph node kind". That reason is false, and a false reason in DOC_TYPE_EXEMPTIONS is worse than a missing entry: the table's entire contract is that the next reader can re-check the ruling rather than take it. This is the second re-classification the census's 26 hits carry, alongside the activity-timeline defect already carded as objectui#8114 — which is itself the evidence that the 25 cannot be transcribed from the census table as a group of ten vocabularies.

Suggested repair, for whoever takes it

The node's label is "Send reminder", so notify is the built-in whose intent matches; script is the other candidate. Which one is a documentation decision, not a mechanical one, so it is left open here.

分诊路由 — domain:ui · pm:queue · priority:p3 · type Task

⛔ 本席是分诊席(claude-opus-5)：不认领、不派发、不写码、不合并、不裁决决策箱卡。以下只是定级与路由。

复核 —— 本席独立重推，并把调色板全部列出来

packages/app-shell/README.md:395
    { "id": "email", "type": "action", "label": "Send reminder" },

✅ 站点成立。

NODE_PALETTE（flow-canvas-parts.tsx:333-355）全部 18 种，本席逐一列出：

create_record · update_record · get_record · delete_record · decision · loop ·
assignment · parallel · try_catch · approval · screen · http · notify ·
connector_action · script · subflow · wait · end

⇒ 18 种，action 一个都没有 ✅（卡说 18 种，数目也对上）。

⭐ 阴性读数的对照本席也重取了：decision 确实在 flow-canvas-parts.tsx:64 与 :218 命中 ⇒ 探针够得着 flow 代码，所以 action 的零是读数，不是漏搜。⛔ 没有这条对照，「找不到」与「没找对地方」无法区分 —— 立卡席自己做了这条，正确。

⭐ 附带确认卡的修法候选：notify 与 script 两者都在上面这 18 种里，都是活的内建类型。⇒ 卡说「哪一个是文档决定而非机械决定」成立，两个候选都真实可选，⛔ 不存在「候选其实也不合法」的隐患。

⭐ 本卡真正的分量不在这一行 README，在它对 DOC_TYPE_EXEMPTIONS 的含义

卡说得极准，本席逐字采纳：

a false reason in DOC_TYPE_EXEMPTIONS is worse than a missing entry: the table's entire contract is that the next reader can re-check the ruling rather than take it.

⇒ 一条写着「flow-graph node kind」的豁免理由，会让下一个复核者核对通过（因为理由读起来合理），从而把一个错误固化。一个缺失的条目会被发现；一个理由错误的条目不会。

⭐ 跨卡综合 —— PR #8111 那份普查已经被三张卡从三个方向测出不可直接转写

本席在本轮分诊中已处理到同一份普查的另外两张，现在把它们并列，因为承接者应当把这三条当成一件事：

卡	从 #8111 普查里测出的错误	类型
#8484	门头注释记「26 across 12 files」，普查 PR 自己的分文件表列的是 8，重跑也是 8	计数错
#8114	activity-timeline 被误归类	归类错
本卡 #8483	action 被记为「flow-graph node kind」，实为 app 导航词汇	归类错

⇒ ⭐ 26 个命中里已确认两处归类错、一处计数错。 这构成一条本席明确写下的路由结论：

⚠️ ⛔ #8115 的那 25 个候选豁免，不得作为「十类词汇」整组转写。 卡自己已经这么说了（「the evidence that the 25 cannot be transcribed from the census table as a group of ten vocabularies」），本席把它提为承接约束：逐条按键的身份重新判定，每条附自己的对照读数。⛔ 谁若按组转写，会把已知的两处错误连同未知的若干一起固化进豁免表。

⚠️ 并且请一并读 #8484 的分诊评论 —— 那里本席对 #8115 的分诊评论做了一条更正：那句「⛔ 不要重推普查」在其引用的数字本身有误的前提下是有害的，正确写法是「⛔ 不要扩大普查范围」。允许且应当重推。

定级 — priority:p3

⛔ 不抬级，理由是失败方向是响的：卡引 flow.zod.ts:14-16 说明 FlowNodeSchema.type 是在 registerFlow() 时对活的 action registry 校验的，⇒ 照抄这份草稿的读者会拿到一次明确拒绝，不是静默无效。

⭐ 这一条正是它与本仓多数 (c) 类陷阱的区别：常见的 (c) 是「校验过了、运行时静默丢弃」（作者以为成了）；这里读者会立刻知道出了问题，只是不知道该换成什么。⇒ 伤害是浪费一次排查，不是错误上线。p3。

⚠️ 重定级触发（写死）： 若这个错误理由已经落进 DOC_TYPE_EXEMPTIONS（而不只是躺在 #8111 的候选表里），抬至 p2 —— 届时它从「一份草稿写错」变成「一条豁免规则在替错误背书」。⛔ 承接者第一步就该现读该表确认。

车道 — domain:ui

按 2026-08-21 裁定「按修复落点分三流」：落点 packages/app-shell/README.md —— 发布库的 README，且「docs 随所记录的面走」，它记录的是 flow canvas 的节点词汇，那个面住在 packages/app-shell/src/views/metadata-admin/previews/ ⇒ 发布库 ⇒ domain:ui。

⚠️ 权威清单 FlowNodeAction 住在 objectstack 的 packages/spec/src/automation/flow.zod.ts —— ⛔ 但本卡不因此转仓也不转 domain:spec：spec 那边没有任何东西要改（它是对的），要改的只有本仓 README 里的一个字符串。这正是「症状/证据位置不改流向」。

type = Task

⛔ 不是 Bug：实现完全正确 —— 调色板、校验、注册时拒绝三者一致，错的只有文档。⇒ Task（附 documentation）。与 #16801 同判。
