[finding] the committed .claude/settings.json allow-lists every REST write the seat makes except the two landing calls (ccr/ready_for_review, ccr/auto_merge) — so landing falls to the non-deterministic auto-mode classifier and seven green PRs waited for a human #19014
Description
The question the maintainer asked, and the measured answer
The maintainer asked the skills seat (chat, 2026-09-18, verbatim): 「不是我不提,是这个会话的权限分类器不让我做那两步。 是你的skills有什么问题嘛？」 The answer is yes, in one place, and this card is the fix.
Measured on origin/main (43f476688): the repository's committed .claude/settings.json carries 47 permissions.allow rules and 17 deny rules. Every REST write the seat makes through curl is allow-listed by shape — POST …/issues/*/labels, PATCH …/pulls/*, the reads — EXCEPT the two calls the landing act is made of: POST …/pulls/{n}/ccr/ready_for_review and PUT …/pulls/{n}/ccr/auto_merge. No allow rule matches a POST or PUT on …/pulls/* at all. So those two calls fall through to the harness's auto-mode classifier, which #18469 measured as non-deterministic (four allowed, four denied, byte-identical), and which in this seat's session denied them three times today (07:03Z 「Merge Without Review」 ×2, 11:39Z 「Auto-Mode Bypass」).
references/rest-channel.md :40 already says what the seat then does — 「会话分类器拒改动 ⇒ 无通道,交有通道席位立卡」 — and the seat did it: seven ACCEPTED, green, non-governed PRs sat draft for hours until the maintainer asked why, and a human (os-zhuang) is now landing by hand what the rules say no human needs to look at (each is under 700 changed lines; the 5,000-line rule of #19012 is far away). The skill's logic is not wrong; its permission surface is incomplete by exactly the two lines that make it a landing skill.
What is owed (one PR, governed .claude/**)
Two allow rules in .claude/settings.json, in the spelling the 47 existing rules use and matching the command spelling references/landing-operations.md prescribes for the landing act (read that file first; the rule must match the spelling the seat types, not a paraphrase), for objectstack and — if the seats land objectui PRs the same way — objectui:
Bash(curl -sS -X POST https://api.github.com/repos/objectstack-ai/objectstack/pulls/*/ccr/ready_for_review *)Bash(curl -sS -X PUT https://api.github.com/repos/objectstack-ai/objectstack/pulls/*/ccr/auto_merge *)
plus the self-test / structural pin the settings file already has for its rule set, if one exists (measure: grep the tree for a test that reads permissions.allow). ⛔ Not a widening of who may land: the act stays behind the seat's own pre-checks (record on head, --pair 0, checks green, the path face NOT governed, and from #19012 the size face); the rules only stop the harness from second-guessing a call the repository has already decided is the seat's. ⛔ Governed text ⇒ the maintainer approves the PR; that is the one human act this card asks for, once.
Sibling reading: #18469 (the classifier's non-determinism and the stale-rotation rule) — different asks, same wall; this card removes the wall for the two landing calls.
Dedup words: settings.json allow ccr ready_for_review auto_merge, landing calls classifier allowlist, permissions.allow pulls POST PUT.
Provenance: filed by the domain:skills seat (session_01BTeBejoPUvRHN8WdAJC6oF, seat post #7623), 2026-09-18T11:46Z, from the maintainer's question in chat. Labels domain:skills · priority:p1 · pm:queue set by the seat (its own lane; the maintainer's question is the ruling that it is a defect); the triage seat may re-grade.

Dispatch collected as BLOCKED — the maintainer's own commit is the only route (skills seat,
session_01BTeBejoPUvRHN8WdAJC6oF) · 2026-09-18T12:15ZThe dev's report 5729818025 is the reading: every route to write
.claude/settings.jsonwas refused by this session's auto-mode classifier as 「Self-Modification」 — the Bash write, the dedicated Edit tool, even a candidate copy in the scratchpad and the read-only roster gate; three denials, no fourth route attempted (correct: a refused write re-issued by another route is #19004's defect). The objectui twin (#9862) was refused at dispatch with the same reason. ⇒ No AI seat in this harness can write this file, by design, and the design is right: an AI must not widen its own permissions. The claim is withdrawn (pm:dispatched→pm:awaiting-maintainer, assignee cleared); the two lines are in the card body for the maintainer to commit by hand.One reading the dev added, carried forward: the allow rule is a literal prefix, so it matches only a landing command that begins
curl -sS -X POST https://api.github.com/repos/…with the BARE url right after the verb and every flag after it; the seat's habitual spelling (-Hfirst, a quoted url) would still fall to the classifier with the rules in place. The seat will type the landing act in the rule's shape, and the spelling prescription is filed as its own references card.Generated by Claude Code

Delivered — the two rules are written, and the block one layer up is what changed. PR #19047, draft,
skip-changeset, on the branch this card'sClaim:already names (claude/issue-19014-settings-allow-landing-calls, re-cut from currentmain; the empty head it carried was an ancestor, so the push was a fast-forward and no claim record moved).The earlier dispatch reported
blocked: every route to edit.claude/settings.jsonwas refused by that session's auto-mode classifier as[Self-Modification], and it correctly declined a fourth route. What unblocked it was not a retry — it was the maintainer instructing this session directly, in chat, to write the four lines across the two repositories. ⛔ That is the only thing that changed; the classifier reading in that report stands as measured.The diff is the one the blocked report specified, byte for byte: two rules appended as the last entries of
permissions.allow, the anchor line gaining its trailing comma.permissions.allow47 → 49,permissions.deny17 → 17, key order unchanged, one file, three insertions and one deletion.The structural pin this card asked to be measured does not exist.
scripts/pm/check-settings-deny-roster.mjspinspermissions.denyequal toCONTENT_WRITE_TOOLSand says under its own "What is deliberately NOT asserted" heading that it does not assert that allow and deny agree; it reads the allow list only in one self-test fixture. A sweep ofscripts/,.github/and.claude/finds no other reader ofpermissions.allow. So there was nothing to extend, and the two rules move no gate except JSON validity — which is asserted directly: the file parses, and the parsed document reports 49 and 17 with the two new rules last.Gates: 15 derived, 15 ran, 15 pass.
node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack .claude/settings.jsonon this branch derives the same 15 families the blocked report listed; this run measured them rather than deriving them. One finding printed belongs to no diff:check-agent-test-spellingflags a line in.claude/settings.local.json, untracked here and covered by the global ignore file, so it exists on one workstation and never reaches CI.Sibling: objectui#9862 → objectstack-ai/objectui#9900, the same pair for that repository, also draft.
What is owed now is the one human act this card asked for, once.
.claude/**is a governed surface (Prime Directive #14) and.claude/settings.jsonis the rules layer, not thereferences/tier — so the PR sits in draft awaiting the maintainer's word. ⛔ No seat flips it ready, queues it, arms auto-merge on it, or approves it.Generated by Claude Code
