skills(pm-dispatch): flip the gate asymmetry — adding a required gate / hook / ratchet joins the human floor; retiring a zero-catch, no-contract gate becomes class-1 (maintainer ruling F)

[hotlong]

Filed and dispatched by the director seat (summon #24, session_01Wj1HUjzyeiBQ8atRf1ZhaL) under the maintainer's ruling F (verbatim 「F」, 2026-09-16 ~14:4xZ) on the direct-channel question 「我们的项目是不是门禁用的太重了。有这个必要吗?」. ⛔ No domain:* set by the filer; the surface is SKILL.md + core-rules.md, anchored to domain:skills.

Dedup terms: gate asymmetry · 人工地板 新增门禁 · 一类自裁 拆门禁 · 门禁加强 免升级

Why (director's reading, on origin/main)

SKILL.md:391 — 「人工地板同含:安全/权限边界;门禁削弱(降阈值、删必查项、抬 ratchet 上限、跳过测试)。」 puts weakening on the floor. Adding or strengthening a gate is free: 具名不升级类 lists 「门禁内部参数与扫描器盲区修复(加强,非削弱)」 and 换班报告 routes every 可机械化项 to 「门禁/脚本卡,⛔ 不是散文」. A fleet under that rule turns every finding into a gate and can never take one down without the maintainer: 182 check-*.mjs, 164 check:* scripts, 42% of last week's 597 merges gate-shaped. The maintainer chose to flip it.

Deliverable — two re-keys, line-neutral (SKILL.md 812/812, core-rules 151/151), each line ≤120 B

1. Human floor gains adding: the 人工地板 line (SKILL.md:391 or its neighbour, wherever it fits in place) reads that a new required gate, a new hook, or a new ratchet is a human-floor item — a seat proposes it as a decision card with the contract it guards and the measured catch it expects; ⛔ it no longer lands zero-baseline on a seat's own warrant. 「门禁内部参数与扫描器盲区修复(加强)」 stays non-escalating only for an existing gate's internals, never for a new gate.
2. Retirement becomes class-1: the class-1 self-adjudication floors (「④ 四类地板零移动 … 门禁强度」) gain the carve-out that retiring a gate the gate census (docs/audits/gate-census-*.md) marks retire — process class, zero real catches, guarding no published contract — is not 门禁强度 movement; the director or the skills seat rules it, records the census row as the authority, and the removal PR follows.
3. references/core-rules.md twin lines re-keyed identically (一条规则两处同改).

⛔ Not touched: SKILL.md:92 (owned by #18468, in flight) and :523 (owned by #18434, queued). This card is serialised behind #18468 (same file): claim after its PR is up, merge main first.

Acceptance

• pnpm check:pm-skill-ratchet 812/812 · 151/151; check:pm-skill-id-lint green; check:skill-frame-sync untouched.
• git grep -n '新增' .claude/skills/pm-dispatch/SKILL.md | grep -c 人工地板 ≥ 1 and the class-1 floor line names the census carve-out (positive greps in the PR body, with controls).
• Governed rules layer: draft PR, 维护者速读(草稿), four-piece; the maintainer's approval lands it.

Refs the gate-census card filed alongside · #18468 · #18434 · #18095

Claim: PM loop round 1 — maintainer direct dispatch to the director seat
Session: session_01Wj1HUjzyeiBQ8atRf1ZhaL
Branch: claude/issue-18473-gate-asymmetry-flip
Worktree: objectstack-issue-18473
Domain: domain:skills
File surface: .claude/skills/pm-dispatch/SKILL.md (the 人工地板 lines around :391–:392 and the class-1 floor line, in place, 812/812) · .claude/skills/pm-dispatch/references/core-rules.md (twins, 151/151) (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: claude-fable-5-1 — dispatch-gates.mjs --tier: SKILL.md path mandate 「MANDATORY: claude-fable-5-1」; no downgrade exit taken
Clause-②: no
Thread-read: none
Serial constraints cleared: SAME FILE in flight — objectstack#18468 → PR #18476 (SKILL.md:92, draft, CI running) and objectstack#18434 (queued, :523); this card edits neither of those lines; ordering by ruling: this PR merges origin/main after PR #18476 lands and before its own enqueue (scripts/pm/os-regen-merge.sh), so the 812/812 ratchet is paid once per PR on disjoint lines; os-verify-lock.sh --status read no holder, no tickets at 14:2xZ

Authority for a director claim: the maintainer's ruling 「F」 on this session's channel (2026-09-16 ~14:4xZ) — item 1 of the three-part proposal — and the standing instruction that the director dispatches these cards directly.

(1) 人工地板 gains 新增必需门禁/hook/棘轮 with the card requirement (卡具名所守契约与预期捕获), paid in place by compressing the weakening examples, spelling 抬 ratchet 上限 as 抬上限 and dropping the repeated 人工地板同含 prefix; the 具名不升级 line is scoped to 既有门禁 … 非新增. (2) The class-1 floor line ③ now ends in ; and continues into :404, which carries the carve-out (门禁普查标 retire 的退役除外,总监/技能席引该行裁) plus its own two clauses tightened. (3) core-rules twins re-keyed identically; the 95–96 block was re-wrapped across both lines to pay 33 B (declared). Draft PR #18481 opened, skip-changeset applied and read back; governed rules layer, stays draft. Card said :391–392 / ④; on base 85c6d76e the lines are :390–391 / :403 ③ (one-line drift, not a false premise). Lines :92 and :523 hash-identical to origin/main. origin/main unmoved at 85c6d76e (os-regen-merge.sh: Already up to date); PR #18476 still an open draft, so no merge landed under this branch yet.

ACCEPT — director seat, session_01Wj1HUjzyeiBQ8atRf1ZhaL, served tier claude-fable-5-1 · 2026-09-16T15:18Z

Verified against GitHub (PR #18481, head 45aeee5d, draft, 2 files +8/−8), ⛔ not against the report — diff read whole on pr/18481 vs origin/main:

• Item 1 (adding joins the floor): SKILL.md:390–391 now read 「…门禁削弱(降阈/删必查/抬上限/跳测);新增运行时第三方依赖;」 / 「- 花费/配额/舰队形态/默认模型档位;新增必需门禁/hook/棘轮(卡具名所守契约与预期捕获)。」; :712 「既有门禁内部参数与盲区修复(加强,非削弱,非新增)」 — a new gate can no longer ride the non-escalation line. Paid in place (no new line).
• Item 2 (retirement becomes class-1): :403 ③ now continues into :404 「门禁普查标 retire 的退役除外,总监/技能席引该行裁;触地板即呈报,地板是排除项非权重。」 — both original clauses of :404 kept.
• Twins: core-rules.md:95–96 re-wrapped to carry 门禁削弱 and 新增必需门禁/hook/棘轮 (every item kept; :95 twins SKILL.md:389 — the one payment that crossed into a neighbour, declared); :137 「既有门禁盲区加强」.
• Line-neutral: SKILL.md 812/812, core-rules 151/151; every touched line ≤120 B (120/119/108/119/117); :92 and :523 byte-identical to origin/main (no collision with PR fix(pm): drop the re-seat prescription — check-harness-current and SKILL.md:92 become a seat-post reading #18476 or finding(pm-dispatch): SKILL.md forbids an off-tier seat from spawning a clause-② review subagent while contract-review.md prescribes exactly that — so a default-tier lane has no legal route to a Clause-② yes verdict at all #18434).
• Gates: 17 derived / 17 run / 0 unrun (--ran, DERIVED zero), all 0 after one prerequisite build; ratchet, id-lint, frame-sync, frame-freshness, governed-prose green; positive greps 1/0 with controls; mcp_calls 0; api_writes 3 REST + 3 pushes, read back; skip-changeset read back. CI on 45aeee5d at review: 14 success · 12 skipped · 3 in progress · 0 failed.
• Deviations answered: the :390 ⛔-zero-baseline half is carried by floor membership rather than spelled — accepted (the floor line is the rule); 「门禁普查」 forward-references [audit] gate census — every check-*.mjs, check:* script, hook and required job on one table: what it guards, real catches since landing, blast radius — and the retirement list (maintainer ruling F) #18472's deliverable — accepted (no gate reads the path; the census PR is in flight); two commits — accepted.

Landing (governed rules layer, ruling C): four-piece hung on PR #18481. Sequencing: merges origin/main after PR #18476 lands (same file, disjoint lines) before its own enqueue. Card stays pm:dispatched until MERGED.
