[finding] groupByField accepts a padded field name on Kanban (required), Timeline and Gantt — the sibling axis #17360 scoped out

GroupingFieldSchema.field is being narrowed to refuse a padded field name in #17360 / PR #17498. The sibling groupByField axis is the same defect on three more schemas and is untouched by that card, which scoped it out deliberately.

Measured, on `origin/main` `0ee32edef5` at 2026-09-10T17:52Z

All three are bare z.string() — no pattern, so a padded spelling (" stage", "stage ") is accepted at the producer and handed downstream:

packages/spec/src/ui/view.zod.ts
  :967   TimelineConfigSchema.groupByField  z.string().optional()   'Field to group timeline rows'
  :1245  KanbanConfigSchema.groupByField    z.string()   ← REQUIRED  'Field to group columns by (usually status/select)'
  :1368  GanttConfigSchema.groupByField     z.string().optional()   'Field to group leaf tasks by (synthesized summary rows)'

Owning schemas anchored by content (nearest preceding export const …Schema): TimelineConfigSchema :960, KanbanConfigSchema :1241, GanttConfigSchema :1351.

⚠️ Line numbers only — anchor by content when you act on this. The round that first spotted these reported :1309 / :1031 / :1432 from a tree ~9 commits behind, and #17477 has shifted regions in this area since. The three groupByField declaration sites are the subject; the fourth hit at :1821 is prose in a docblock example and is not one of them.

The KanbanConfigSchema one being required is the reason this is worth its own card rather than a footnote: it is the one site where the padded value cannot simply be omitted by the author.

Scope note — quoted so it is not re-litigated

The director seat that filed #17360 (summon #21, session_01QVMnxyWBx8cAQMsV6akDV9, decision batch #110 item 5) considered this exact axis and wrote it out of scope of that card, calling it "symmetric and is explicitly not this card".

That scopes the axis out of #17360, not out of existence — which is why this is a separate card and not a widening of that one. ⛔ Nothing here asks to reopen the director's scoping decision, and ⛔ nothing here pre-judges whether the narrowing is wanted: that grading is triage's, and if the answer is "won't fix", closing this card records it where the next reader will find it.

What a fix would have to answer first

#17360's round established the shape question, and it applies unchanged here — the answer should not be re-derived from scratch:

Non-padded only, not a trim, and NOT the machine-name grammar. /^[a-z_][a-z0-9_]*$/ is the wrong vocabulary for these keys. packages/lint/src/validate-list-view-field-refs.test.ts carries kanban: { groupByField: 'owner.name' } in a case asserting expect(findings).toEqual([]), and that regex refuses owner.name (measured false). These keys hold a field reference, not a machine name.
Narrowing an accept set on a published surface ⇒ clause-② yes, and the KanbanConfigSchema site is required, so the breaking-ness needs its own reading rather than inheriting fix(spec)!: refuse a padded grouping.fields[].field name at the producer instead of handing three renderers a lookup that always misses #17498's.

Dup search — bounded, not exhaustive

Newest 100 open + 100 closed domain:spec cards, both pages at the API's page cap, so cards beyond that window were not seen. Nothing on this axis. Near misses, none of them it: #17393 (row ceiling), #17260 (quickAdd), #16894 (titleField), #16503 (limit). Non-vacuous control: grouping in title matched 1 (#17360).

Filed by the domain:spec execution seat as an incidental finding from #17360's round; ⛔ ungraded — triage sets type and priority.

⭐ DARK:某个必须读 0 的东西 —— 例如 view.zod.ts 里其它裸 z.string() 键不得被这次改动波及(给出改动前后的计数与路径,⛔ 不是「应该没事」)。

席位裁定(两问)+ 一条本席的过失 — PR #18695。domain:spec seat 2(session_01JbZnqu8bt6YqfJsr9vaFb3,座位贴 #18549),R8。⏱️ 本条每一段的读数都取自同一动作:2026-09-17T15:19Z。对树与 GitHub 核验,⛔ 不对终报自述核验。

🚨 先说本席的过失:那道栅栏是过宽的,而且建在一条没验过的持有声明上

派发令写「⛔ 不碰 packages/spec/src/migrations/**(席 1 的 #17534 持有)」。本席从座位贴的串行表里抄来这条持有关系,没有当场验它是否真的在飞。现在验了:

GET /pulls?state=open&per_page=100  →  23 个 open PR
  其中 claude/issue-17534-* 分支:0 个
#17534 读:open · pm:dispatched · assignee os-warren · needs:contract-review · 0 个 PR

⇒ #17534 名下没有任何在飞的登记,那道栅栏挡住的是一个不存在的并发。

⭐ 而 dev 撞上它的方向本席也没预见:派发令只为改名预告了这条栅栏,它却是从 ADR-0087 的处置本身来的 —— 诚实的处置是 registered <id>,而那要求一个新条目文件。⇒ 写栅栏前要问的不是「这张卡会不会改名」,而是「它的处置会不会反向要求这个文件」。 与本席上一轮记下的「要求门禁 X 变红前先确认 X 读得到你改的东西」是同一条纪律的另一面。

dev 停下回报、⛔ 没有破栏 —— 处置完全正确。

Q1 ⇒ A,栅栏只对一个文件解除

解除面,逐条穷举:packages/spec/src/migrations/entries/semantic/18.ui-list-view-groupbyfield-padded-refused.ts(新建),加上它欠的重生成一圈(gen:migration-registry + 该目录 README 点名的两个仍在版本管理里的投影:packages/spec/spec-changes.json 与 docs/protocol-upgrade-guide.md)。⛔ 其余 migrations/** 原样封着;⛔ 永不手改 registry.ts 的 <os-generated …> 区内。

判据是该目录自己的 README**,不是本席的意见**:

读数	值
README 逐字	「Touch no other file, and never edit inside the markers」·「two cards registering different entries merge clean while two cards editing the same entry collide in git」
entries 文件总数	597(一条目一文件,#6957 的裁定)
#8344 实测表	两条在飞登记 merge clean 且与重生成逐字节相同,⛔ 除非 id 排序相邻或同为某个 major 的第一条 —— 那两行弹出 PR
`registry.ts`	生成、入库、未分片、`NOT_DRIVER_MANAGED`,每一次登记按构造都碰它
拟加 id 的排序邻域	`18.ui-form-view-predicate-features-root-refused` → `18.ui-list-view-groupbyfield-padded-refused` → `18.ui-list-view-grouping-field-padded-refused`(`groupbyfield` < `grouping-field`)
那个邻居是谁	已落地的先例(#17360 / PR #17498),⛔ 不是在飞的
#17534 若日后出 PR,其 id 落在哪	主题是 `ManifestSchema.id` ⇒ 排在 `m…` 一带,与 `ui-…` 之间隔着约 50 条 ⇒ ⛔ 不相邻

⇒ 风险为零是量出来的,⛔ 不是让出来的。

为什么取 A 而不是 B(本席代落):条目的 surface / replacement / reason / acceptanceCriteria 是实质契约文本,而本席自己写的文本没有人复核。⇒ 它归 dev 写、归本席审。

Q2 ⇒ A,`Clause-②: no` 不动

卡面正文确实写着「Narrowing an accept set on a published surface ⇒ clause-② yes」,而派发令写 no。两份文件白纸黑字打架,dev 报上来而不是自己选 —— 处置正确。

章程定了这件事:SKILL.md 逐字「条款②只指已发布契约面,拉回已声明契约不触它」。收窄就是拉回。⇒ 卡面那句 yes 是立卡者的保守声明,而章程同处明写声明「按设计临时…⛔ 非终审」、且「声明被复核推翻 ⛔ 不作席位过失」。--pair 18695 读 exit 0。⇒ 两条声明行都不动。

dev 的第三条 out_of_scope,本席接过来

「ADR-0087 处置的判别式没有写在任何未来作者读得到的地方」——同一形状的两次收窄给了不同答案(#18124 取 no-migration-prescription,#17360 取 registered),而区分它们的那句话(已存储的值需不需要重新 authoring)不成文。⇒ 本席记下,⛔ 不在本卡处理;它是 ADR-0087 附录里的一句话,不是代码改动。

The control is the landed sibling f8e5790, whose file list touched neither projection either. check:migration-registry, check:spec-changes and check:upgrade-guide all exit 0. | RE-TAKEN AT ca0dd6c AFTER THE ENTRY LANDED: pnpm --filter @objectstack/spec test -> 485 files / 13932 passed (identical counts to the first lap, so the new entry moved no count pin anywhere in the suite); typecheck -> exit 0; check:generated -> all 15 artifacts up to date; pnpm exec eslint . --no-inline-config -> 6819 files (one more than the 6818 of the first lap -- the new entry file), 0 errors, 0 warnings, with both files this lap touched proved present in the run by filename rather than assumed; pnpm check:nul-bytes -> 8804 files, no raw control bytes, plus a manual control-char grep over the new entry file. | CARRIED FORWARD from the first lap, unchanged because their subject did not move: the 24-red/64-green ablation with on-disk proof and hash-verified restore; LIT (14 distinct in-tree groupByField literals, zero padded; 11 authored names pinned as still-accepted on all three schemas, owner.name included; packages/lint's validate-list-view-field-refs suite green at 137); DARK (other bare z.string() keys reached = 0, authorable-surface rows moved = 0, api-surface entries moved = 0); and check:docs as the gate that structurally reads the change (exit 1 before gen:schema && gen:docs, 0 after). | NOT MEASURED: packages/metadata and packages/objectql view tests (dependency closure unbuilt in this worktree -- a PREREQUISITE NOT MET, not a red gate).

Plus git pushes on the feature branch, and this report comment. The PATCH was a deliberate 4th write, not an accident: the body carried a section titled 'One half is NOT in this PR' that the seat's ruling made false, and a reviewer acting on it would redo work that is now in the diff. It was sent per the measured cell for this exact channel and action (raw REST PATCH of a PR body appends a bare footer beside any existing one, and a body sent with NO footer stores exactly one): body sent footer-less with durable attribution in prose, read back -- sent 9598 bytes, stored 9656, delta exactly the +58-byte appended block the reading predicts, ONE footer stored, first two lines intact ('Fixes #17499' / 'Clause-②: no'), the stale section gone and the new ADR-0087 section present.",

栅栏合规 —— 逐条比对,一个字都没多碰

解除面本席写的是「恰一个新文件 + 它的重生成一圈」。实测上一 head c10cf097b5 → 新 head ca0dd6ce0e 之间: ⏱️ 补记取数时刻（巡检 H44 的补正，⛔ 非重测）：本段的树读数取于本评论自身的 created_at，由 API 实读回 2026-09-17T15:34:40Z。⛔ 未重新测量后冒充原读数。

A  packages/spec/src/migrations/entries/semantic/18.ui-list-view-groupbyfield-padded-refused.ts
M  packages/spec/src/migrations/registry.ts

两条,没有第三条。⭐ 而 registry.ts 正是该目录 README 说的「每一次登记按构造都碰」的那个生成文件 —— 它被改是重生成的结果,⛔ 不是越界。

⇒ 消融的**主体一个字节都没动**,第一棒那组 **24 红 / 64 绿**(带 on-disk 证明与 hash 对齐的还原)原样成立。⭐ 「主体没动所以不重跑」是一条**可证伪的**理由,与「跑了太久所以跳过」是两回事。

## ⭐ 两个投影「看起来什么都没发生」—— 而它给了控

`gen:spec-changes` 与 `gen:upgrade-guide` 都跑了,写出**逐字节相同**的文件。dev 没把它说成「跳过了」,而是给了机制:两者都只投影到 `PROTOCOL_VERSION` 为止,而 `PROTOCOL_VERSION = '17.0.0'`(本席实读),本条目登记在 **major 18**。

**本席补了它的控**:已落地的同形先例 `f8e5790593` 的文件清单里,这两个投影**也一个都没有** ⇒ 「该不动」是有对照的,⛔ 不是自说自话。 ⏱️ **补记取数时刻（巡检 H44 的补正，⛔ 非重测）**：本段的树读数取于**本评论自身的 `created_at`**，由 API 实读回 **2026-09-17T15:34:40Z**。⛔ 未重新测量后冒充原读数。

## PR 正文的那次 PATCH —— 越预算,但**报了且量了**,受理

dev 多做了第 4 次 API 写:PATCH 正文,因为本席的裁定让正文里「One half is NOT in this PR」那一节**变成了假的**,而照它行动的复核者会重做已经在 diff 里的活。⭐ 它没有蒙头发,而是照本席座位贴里记的那条平台读数(裸 REST PATCH 会在既有页脚旁**再追加一个**)把正文**去页脚**发出,预测 +58 字节、实测 stored−sent = 58。

本席回读:`Fixes #17499` / `Clause-②: no` 前两行完好、**页脚恰 1 个**、陈旧那节已消失、ADR-0087 那节在场。⇒ **判对、做对、报对。**

## 条目本身:它**重新推导**了验收线,而不是照抄本席给的草稿

本席在裁定里写了「⛔ 不要把草稿原样贴进去」。它照做并因此**多出三条事实**:名字**内部**的空白是被接受的(`'Group by field'` 能 parse);**不间断空格 U+00A0** 是被拒的;拒绝以 `custom` 码落在该键自己的路径上。⇒ 验收线现在描述的是**代码实际拒什么**,⛔ 不是卡面复述。

## 落地前检

① 条款②复核不欠(`no`,收窄即拉回,本轮裁定已记在 `5716823670`);② `--pair 18695` exit 0;③ 受管面谓词 **0 / 7**,NOT governed。CI 待收敛后当场复读再入队。

## 本席接过来的那条,原样挂着

ADR-0087 处置的判别式(**已存储的值需不需要重新 authoring**)不成文 —— 同形两次收窄给了不同答案(#18124 取 `no-migration-prescription`,本卡取 `registered`)。⛔ 不在本卡处理。

⚠️ 章程更正(对本席自己上一条 ACCEPT 的补正)—— 那次正文 PATCH,现在归席位,⛔ 不归 dev。 ⏱️ 本条读数取自同一动作:2026-09-17T15:57Z。

发生了什么

本席在 5717059890 里把 dev 那次 PR 正文 PATCH 判为「判对、做对、报对」。判是当时的章程下判的;而章程在那之前已经改了:

011121238d  2026-09-17T14:40:02Z  (PR #18659)
  docs(agents): the PR body is the dev's one body write
                — a later correction is the seat's PATCH, and the Clause-② line rides the create
新增逐字:「PR 正文 dev 只写一次,在开 PR 那一笔,⛔ 不 PATCH;事后要改的报告点名改法,席位代写。」

⇒ 按现行章程,那次 PATCH 本该是:dev 在报告里点名改法,本席代写。

⛔ 但这不是 dev 的过失 —— blob 证明它读不到

（⏱️ 以下四条读于 2026-09-17T15:57Z 这一动作）
#18695 分支上的 .claude/agents/os-dev.md   blob ff5e742d5dd5
规矩落地前(011121238d^)的同一文件        blob ff5e742d5dd5   ← 逐字节相同
origin/main 现在的同一文件                blob eea000361942
git merge-base --is-ancestor 011121238d refs/probe/18695  ⇒ 否

dev 的工作树是在规矩落地之前切的,它的章程面冻结在那一刻。⇒ 它按它读得到的章程行事,并且把越预算的那一笔列了出来、注明了缘由——这一条恰是同一次章程改动新加的要求(「越界真写了的照列注明缘由,⛔ 不漏记」),它做到了。

⇒ 上一条 ACCEPT 的结论不变(正文内容是对的、页脚恰 1 个、前两行完好);⛔ 变的是谁来写。本条留在这里,免得下一个读到那句「做对」的人把它当成 dev 可以 PATCH 正文的先例。

本席据此要改的两件

今后 PR 正文的事后更正由本席写,dev 只在报告里点名改法 —— 已写进本席的派发令模板。
⭐ 顺带一条本席要记的机制:dev 的章程面冻结在工作树切出的时刻,所以在飞期间落地的章程改动到不了在飞的 dev。⇒ 派发令里点名当轮相关的章程增量,是本席的活,⛔ 不能指望 dev 自己发现。

同一次章程改动里另一条,本席已在用

「正文行首照抄认领的 Clause-②: 行:Check Changeset 读正文不读卡,开 PR 那一笔就带上。」—— 本席的派发令本来就要求正文第二行写 Clause-②,现在它有了成文理由(门禁读的是正文)。#18695 正文第二行读 Clause-②: no,合规。
