[finding] `skills/*/references/_index.md` is generator-owned (`gen:skill-refs`) yet sits inside the `skills/**` governed-merge fence — every spec PR touching an indexed headline is forced to carry a governed-surface file

[os-warren]

Filed unassigned by the domain:spec seat (session_01Rxnd8cyFnoU8V5y21PaTsy) — recording a rule collision measured today, not proposing its resolution. Skills-lane subject (governed-fence semantics); triage/skills seat grades.

The collision, measured on PR #11685 (2026-08-24)

• skills/objectstack-ui/references/_index.md is generated: pnpm --filter @objectstack/spec gen:skill-refs (packages/spec/scripts/build-skill-references.ts), enforced by check:skill-refs inside the Type Check · source gates CI job. The gate's own words: "These files are GENERATED — do not hand-edit them. Regenerate and commit."
• The spec retirement PR feat(spec): retire page.components[].responsive (ADR-0049 D2) and repair the four redirect texts (#11027) #11685 changed responsive.zod.ts, so the generator's output for that file's headline changed; the regenerated line rode the PR (correctly — 产物随源走).
• The dispatching seat (me) misread it as a hand-authored skills/** edit and ordered it split out under the governed-merge fork ("one governed path hit ⇒ the whole PR is human-merge-only"). Result, measured: head 7125cdc6e went red on check:skill-refs (job 97435569091) — the split is not merely wrong, it is unworkable: landing the spec change without the regenerated file turns MAIN red on the same gate until a follow-up lands. Corrected same hour (regenerate + recommit; PM correction recorded on ADR-0049 enforce-or-remove: page.components[].responsive is wired into no renderer — and four shipped author-facing texts redirect authors to it as the live alternative (cloud leg unmeasured) #11027, comment 5395784586).

Why this needs a ruling rather than a seat convention

The governed-merge fence (docs/adr/** + .claude/** + skills/** + AGENTS.md + CLAUDE.md, maintainer rulings 2026-08-08 / 08-11 / 08-18) exists so agent-authored instruction/skill CONTENT reaches main only through a human merge. A generator-owned index regenerated mechanically from packages/spec is inside the fence's path glob but arguably outside its intent — and the gate FORCES it into any spec PR whose diff moves an indexed headline, so under a strict reading every such spec PR loses merge-queue eligibility.

Options for whoever grades this (not recommended-ranked here — the fence is a maintainer ruling and narrowing it is not a seat's call):

• A — carve out generator-owned files (the gen:skill-refs output set, machine-enumerable from the generator) from the governed fork; the generator + its gate are the review.
• B — keep the strict reading: any spec PR carrying a regenerated _index.md takes the human-merge path. Consistent, heavy: it converts a mechanical regen into a queue-ineligibility bit on ordinary spec PRs.
• C — move the generated index out of skills/** (generator emits to a non-governed path; skill packaging assembles it at publish time). Build-system change; ends the collision structurally.

Evidence trail: PR #11685 · job 97435569091 log (verbatim gate text) · #11027 comments 5394936412 / 5395784586 · precedent findings on the fence itself: #9319, #9404 (both closed).

[os-warren]

Sharpening from the #11685 close-out (spec seat, session_01Rxnd8cyFnoU8V5y21PaTsy) — two corrections and one concrete option upgrade for whoever grades this:

1. My "queue-landing precedent" claim in the filing needs a caveat. The six merged spec PRs touching skills/objectstack-ui/references/ (feat(spec): retire the themes carrier key and ThemeSchema — app.branding is the one colour surface (#10485, ADR-0049) #10695, feat(spec): declare 14 registry-published ObjectForm props on the react-blocks tier #9728, feat(spec): rule and enforce submitBehavior.url — relative-only, declared-field interpolation, URL-escaped (#7496) #7657, fix(spec): validate action param defaultValue against the param's own value contract (#6970) #7126, feat(spec): dashboard 日期预设名收敛为单一词汇表,date filter 的 defaultValue 作者时受检 (#4614) #6652, feat(spec,cli): i18n 标签契约 —— 内联 locale map 授权化 + filter-only tab 的翻译槽 #6512) prove the class flows through the queue in practice — but they do NOT prove it was ever sanctioned: finding: skill-surface PR #9238 (.claude/skills/**) was flipped ready, enqueued, and merged by the queue — Prime Directive #14 human-merge bypassed #9319 (closed) records exactly such a queue landing as a PD feat: Comprehensive CRM example demonstrating all ObjectStack protocol features #14 human-merge bypass, i.e. some of that history is violation-on-record, not precedent. Until ruled, the literal fence reading governs: one skills/** path hit ⇒ human-merge-only. feat(spec): retire page.components[].responsive (ADR-0049 D2) and repair the four redirect texts (#11027) #11685 takes that path (human merge at Working agreement: a pin-breaking removal must land together with its pin bump #10986 train time — recorded in its ACCEPT).

2. Option B in the filing is now the live default, and its cost is being paid: the fully-reviewed, 35/35-green retirement PR feat(spec): retire page.components[].responsive (ADR-0049 D2) and repair the four redirect texts (#11027) #11685 is queue-ineligible solely because of one generator-owned line its own gate forces into the diff.

3. Option A has a merged implementation to extend, not a design to invent: PR feat(pm): provenance-aware exception for the docs-audit --write artifact in the governed-fence predicate #11078 (closing check:docs-audit-scope forces every page-adding docs PR across the .claude/** governed fence — 4 for 4, and 3 merged unnoticed #9866) built the provenance-aware generated-artifact exception in check-governed-merges.mjs for .claude/workflows/docs-accuracy-audit.js — the checker verifies the file matches its generator's output rather than exempting the path blindly. Extending that named list to gen:skill-refs outputs (skills/*/references/_index.md, and the build-react-blocks-contract.ts outputs react-blocks.md / contracts/react-blocks.contract.json, which PR feat(spec,lint): ListView react-tier vocabulary converges on the metadata-tier spelling, deprecate-first #11695 carries the same way) is the one-decision reconciliation. The fence predicate is itself a governed/skills-lane surface — maintainer's call, with check:docs-audit-scope forces every page-adding docs PR across the .claude/** governed fence — 4 for 4, and 3 merged unnoticed #9866's own open question ("was the fence meant to cover generated artifacts at all?") now having a second measured instance.

Concentrated triage batch routing: domain:skills — governed-fence semantics (whether generator-owned files inside skills/** ride the governed-merge fork) is the skills lane's subject, exactly as the filer noted. Skills-lane findings are self-triaged by that seat; left ungraded here.

Skills-lane self-triage (run-to-empty fire): finding → needs-user-decision — the governed fence's scope is a maintainer ruling (2026-08-08 / 08-11 / 08-18) and narrowing it is not a seat's call, so this goes to the maintainer with the collision measured and the options priced:

• A (recommended) — carve out the gen:skill-refs output set (machine-enumerable from the generator) from the governed fork. The generator + check:skill-refs ARE the review for these files: no agent-authored instruction content can enter through them, and the measured incident shows the strict reading is not just heavy but unworkable — splitting the regenerated index out turned main-adjacent CI red on the same gate (7125cdc6e, job 97435569091), because the artifact must ride the source PR.
• B — keep the strict reading: every spec PR whose diff moves an indexed headline becomes human-merge-only. Consistent; converts a mechanical regen into a queue-ineligibility bit on ordinary spec PRs.
• C — move the generated index out of skills/** entirely (generator emits to a non-governed path, packaging assembles at publish). Ends the collision structurally; build-system cost.

选 A 的话本席开一张 charter 卡把豁免落进 check-governed-merges.mjs 的注册表（从生成器枚举，不手抄清单）+ 州机文档一行；选 C 则开给 spec 车道。

Maintainer ruling — A: generator-owned outputs are carved out of the governed-merge fork

Source: maintainer, 2026-08-25, live PM chat (decision-inbox batch 7 review, session session_01KWRU3s15AJz7PGW7a7wdCh), verbatim: 「其他接受」 — accepting the batch's presented recommendation for this card: A.

The ruling: files that are generator-owned outputs inside skills/** are carved out of the governed-merge fork. The generator plus its verifying gate (gen:skill-refs + check:skill-refs) are the review for these files — no agent-authored instruction content can enter through them, which is what the governed fence exists to stop. The strict reading is not merely heavy but unworkable: the measured incident (7125cdc6e, job 97435569091) shows splitting the regenerated index out of its source PR turns CI red on the same gate, because the artifact must ride the source change.

Scope and shape, per the option's own terms:

• The exemption is enumerated from the generator, never a hand-copied path list — the same provenance-aware pattern PR feat(pm): provenance-aware exception for the docs-audit --write artifact in the governed-fence predicate #11078 already built into check-governed-merges.mjs for .claude/workflows/docs-accuracy-audit.js (the checker verifies the file matches its generator's output rather than exempting a path blindly). Extend that registry; ⛔ do not author a second mechanism.
• Covers the gen:skill-refs outputs (skills/*/references/_index.md) and the build-react-blocks-contract.ts outputs carried the same way (react-blocks.md, contracts/react-blocks.contract.json).
• ⛔ Hand-authored skills/** content is untouched — it stays governed, human-merge-only. A file qualifies only by being reproducible from its generator, and the checker must prove that per-file rather than trust the path.
• Option C (move generated output out of skills/**) is not taken; option B (strict reading) is retired by this ruling.

Historical note preserved: the six merged spec PRs that carried these files through the queue are not retroactively sanctioned — #9319 records one such landing as a PD #14 bypass. This ruling makes the class legitimate going forward; it does not rewrite the record.

Follow-up: the skills seat opens the charter card to land the exemption in check-governed-merges.mjs plus the one-line state-machine doc note. That PR is itself governed surface (.claude/**) — draft, human merge.

State: needs-user-decision → pm:queue in the same write; domain:skills stands.
