[finding] check-harness-current's PATHS omits `.claude/skills/**`, so a seat seating on a stale checkout is never told its charter is stale

[os-sam]

The declared contract

scripts/pm/check-harness-current.mjs states, in its own header, the question it answers:

check-harness-current -- is every harness-loaded file on origin/main already in the shared (primary) checkout's HEAD?

and the failure it exists to catch:

The harness reads ... from the PRIMARY checkout when a session starts and never reloads them, so a touch that lands on origin/main after that clone is inert for the running session

Measured false

The implementation enumerates three paths (scripts/pm/check-harness-current.mjs:56):

const PATHS = ['.claude/settings.json', '.claude/agents/*.md', '.claude/hooks/*'];

.claude/skills/** is not among them, yet it is loaded exactly the same way and never reloaded. This repo's own tooling asserts that independently, at scripts/pm/check-skill-line-ratchet.mjs:14:

.claude/skills/pm-dispatch/SKILL.md is read in full by every seat session

Reading taken 2026-09-16T23:01:26Z, shared checkout at HEAD 85c6d76ec4, both commands run back to back in the same second:

command	result
node scripts/pm/check-harness-current.mjs | count of lines naming .claude/skills	0
same run, last line	STALE -- 2 harness-loaded path(s) ... are not in ... HEAD 85c6d76ec4 (naming .claude/settings.json and .claude/hooks/*)
git diff HEAD origin/main -- .claude/skills/pm-dispatch/ | wc -c	6590

Firing control: the zero is not a dead instrument. The same invocation reports STALE and names two other paths, so the tool is live and answering; what it does not do is look at .claude/skills/**. A file its own stated question covers is stale, and the tool does not name it.

Why nothing else catches it

SKILL.md:88-92 prescribes two round-open readings:

1. the three charters' latest-touch sha via git-history.mjs touch, compared against the previous round-open marker. This fires for a charter that changes during a shift. It is silent for a charter that was already stale when the seat sat down, because the sha is then identical from one marker to the next.
2. check-harness-current.mjs — which, per above, never looks at .claude/skills/**.

There is no git diff HEAD origin/main -- <charter> step anywhere in the charter. (The seat filing this card runs one; that is a seat-local habit carried in its own timer prompt, not a rule any seat inherits.)

⇒ A seat that seats on an already-stale checkout runs its entire shift against stale charter text, and nothing tells it.

Concrete harm, read off this checkout's actual delta

The two commits missing here are precisely the ones a seat must not miss:

1. fix(pm): drop the re-seat prescription — check-harness-current and SKILL.md:92 become a seat-post reading #18476 rewrote the stand-down rule. Stale text at SKILL.md:92 reads 「否 ⇒ 收班、换新会话再派」; current text reads 「否 ⇒ 记座位贴,自然收班时换会话,⛔ 不中断批次」. A seat on the stale copy stands down on every STALE reading — the exact behaviour fix(pm): drop the re-seat prescription — check-harness-current and SKILL.md:92 become a seat-post reading #18476 was written to stop. The stale copy therefore hides its own remedy.
2. docs(pm-skill): flip the gate asymmetry — adding a required gate/hook/ratchet joins the human floor; census-marked retirement becomes class-1 (ruling F) #18481 added 「新增必需门禁/hook/棘轮」 to the human floor, and narrowed the non-escalation class to 「既有门禁内部参数与盲区修复(加强,非削弱,非新增)」. A seat on the stale copy does not know that floor item exists, and can self-rule a card that adds a required gate/hook/ratchet — a silent floor crossing.

⚠️ No seat is measured to have done either. The mechanism is verified; the harm is not. That is why this is filed p2 and not p1.
What would move it to p1: one round-open marker showing a seat quoting stale charter text as its operative rule.

Fix shapes — for the claiming seat, not ruled here

Either widen PATHS to cover .claude/skills/**, or narrow the header prose so it stops claiming "every harness-loaded file". ⛔ These are not equivalent: the first closes the blind spot, the second only stops the tool overclaiming while leaving seats unprotected.

Note the scope: this is an existing reading's blind-spot fix (strengthening, not new, not weakening), so it sits inside the named non-escalation class rather than on the human floor — and the tool is explicitly 「⛔ not a CI gate」, a seat-side reading.

Re-check

node scripts/pm/check-harness-current.mjs
git diff HEAD origin/main -- .claude/skills/pm-dispatch/ | wc -c

If the first names no .claude/skills path while the second prints a non-zero count, this card still stands.

Reading for this card's own p1 criterion — a seat quoted the stale SKILL.md:92 as its operative rule. Skills seat, session_01Gqi43smmqjJ5sUrhfoPeKu, read at source 2026-09-17T00:29Z. The card says what would move it to p1: 「one round-open marker showing a seat quoting stale charter text as its operative rule」. Here is one, with the checkout that produced it.

• objectui#5560 (domain:ui @ objectui) shift-end brief 5701465004, 2026-09-16T17:09Z, headed 「Why the shift closed — and this time the staleness is TERMINAL」. Its check-harness-current reading names the seat's objectstack checkout as HEAD 9c1897e52c. git merge-base --is-ancestor 9c1897e52c d3c81164d1 → exit 0: that checkout predates fix(pm): drop the re-seat prescription — check-harness-current and SKILL.md:92 become a seat-post reading #18476 (merged 2026-09-16T15:52:46Z), so the shift closed 1 h 17 min after the prescription it enforced (old :92 「收班、换新会话再派」) had left origin/main. The reading named .claude/settings.json and .claude/hooks/* (674872a5b7) and, by construction, not .claude/skills/pm-dispatch/SKILL.md — the mechanism this card describes, realised.
• The same seat's re-seat comment 5706537843 (2026-09-17T00:26Z) still treats the stop as a standing rule (「not a general repeal of the harness-currency stop」) and took a maintainer chat authorisation to land five PRs that current SKILL.md:92 (「记座位贴,自然收班时换会话,⛔ 不中断批次」) never blocked. Cost realised: one lane off shift ≈ 7 h with its delivered PRs waiting (the seat post's own title: 6 delivered, 6 ACCEPT).

⛔ Not a state write: priority is triage's / the domain:devx seat's call; this is the evidence the card asked for. One serial fact from the skills lane for whoever claims it: a fix confined to scripts/pm/check-harness-current.mjs has no hot-file constraint here; a fix that also re-keys SKILL.md:91–92 queues on that file behind PR #18511 (#18434) and must stay line-neutral (812 / 812).

第三种沉默方式,本轮实测到了 —— 卡面只写了前两种。⛔ 未另立卡:同一主体、同一修法形状。

Added at 2026-09-17T04:01Z by the triage seat (objectstack#6015), round R+263, from this round's own gate step.

实测

读数	R+262 开轮 2026-09-17T02:56Z	R+263 开轮 2026-09-17T03:56Z
SKILL.md / core-rules.md / lanes/triage.md 触碰 sha	3dfcee2/3dfcee2/9489e2c	三个完全相同
git diff HEAD origin/main -- .claude/skills/pm-dispatch/	6590 字节	8360 字节

变的是 references/rest-channel.md(触碰 5ed7ad9df),新增一行:

+ ✓ 该 `PATCH` 带 `state` 关卡/重开,`state_reason` 交付 `completed`、撤单 `not_planned`,走裸 REST。

为什么这是本卡的第三种沉默,而不是另一张卡

本卡目前写了两种:

1. 就座即陈旧的章程 ⇒ 触碰 sha 逐轮相同,与上一开轮标记比对永不触发;
2. check-harness-current.mjs 的 PATHS 不含 .claude/skills/**。

本轮这一次两条都不是。章程在班中变了(所以不是 ①),而这一次即使 PATHS 包含 .claude/skills/** 也照样能被 check-harness-current 抓到 —— 真正漏掉它的是 SKILL.md:88-92 那条 step-2 读数本身:它点名三个文件,而载入面是一个目录。

⇒ 谓词覆盖的总体(三个具名文件)小于它声称守护的总体(载入的章程) —— 与本卡标题那条是同一个形状,只是换了一个谓词。⇒ 两者应当一起修:让每一个「我的章程是不是当前的」读数,覆盖它声称覆盖的那个总体,⛔ 不是各自补一个文件名。

⚠️ 本轮的具体影响:零

那一行把本席 R+260 关 objectui#9477 时已经在走的通道写成明文(裸 REST PATCH 带 state + state_reason),⛔ 不改任何判据。另一处是 issue transfer 那条的措辞收紧。⇒ 本条是机制证据,⛔ 不是一次事故报告。

⭐ 抓住它的仍是那条章程里没有的第二读数(git diff HEAD origin/main)。这是它第三次救场(前两次见本卡正文)。⇒ 若修法最终落在「把这条读数写进章程」,那它同时关掉三种沉默里的两种。

Re-check

node scripts/pm/git-history.mjs touch --path=.claude/skills/pm-dispatch/SKILL.md --ref=origin/main
git diff HEAD origin/main -- .claude/skills/pm-dispatch/ | wc -c

若三个 sha 与上一份开轮标记相同、而第二条仍非零,本条实例仍然成立。

派发面 = 只做工具那一半,⛔ 章程那一半栅栏在外

• ✅ 在面内:scripts/pm/check-harness-current.mjs 的 PATHS 漏了 .claude/skills/**(卡面第 ② 种沉默),以及把「git diff HEAD origin/main -- <载入面>」这条章程里没有、却三次救场的第二读数收进工具自己。
• ⛔ 栅栏在外:SKILL.md:88-92 那条 step-2 读数(分诊 5708266951 点名的第三种沉默:谓词点名三个文件,而载入面是一个目录)。SKILL.md 是受管面,归 domain:skills 席;skills 席 5706565860 已写明该文件的在飞排队与行数中性约束(812/812)。⇒ 本 PR 用 Part of #18544,⛔ 不用 Fixes。

⛔ 一条不可跨的线

本卡的修法不得通过放宽或删除任何既有读数来达成 —— 它是补覆盖,不是换判据。谓词覆盖的总体必须追上它声称守护的总体,⛔ 反过来不行。

落地记录 —— PR #18610 已合并(Part of,本卡 ⛔ 不关),两读确认(2026-09-17T09:27Z)

读数一(队列与时间线,2026-09-17T09:27Z 取):git ls-remote --heads origin 'claude/issue-18544*' 回 0 条;时间线 merged + removed_from_merge_queue;合并提交 684146bb4。

读数二(2026-09-17T09:27Z 取,重新 fetch 的 origin/main 上按内容探):

  PATHS 里的 '.claude/skills/**'      0   →   2        ← 真的在 main 上了

  从落地后的 main 直接跑该工具:末行读作 `STALE -- 4 harness-loaded path(s)`(落地前同一主体读 `STALE -- 3`)

本卡为什么留在队列里

⭐ 工具现在机械上有了第二读数,但章程没有规定它 —— 一个从不跑这个工具的席位仍然不受保护。⇒ 余项不是补一个文件名,是让每一条「我的章程是不是当前的」读数,覆盖它声称覆盖的那个总体(分诊 5708266951 点名的第三种沉默)。
