Provenance: maintainer ruling 2026-08-27 (PM chat, decision-inbox batch 1, adjudication session session_01DKWDdUJ2XNRESVVWUvcpnh), verbatim: 「同意,并继续」 — accepting Option A + C on #6325. Option C is this card: the un-reviewed AGENTS.md merge stands (audit record on #6325), and the governed-surface no-bypass rule becomes machine-enforced so the next incident does not depend on seat discipline.
Why seat discipline is not enough (measured incident)
PR #6183 (governed surface: AGENTS.md) was correctly draft-parked; a GitHub MCP update_pull_request call passing only reviewers silently set draft: false; the PR entered the merge queue and merged as 5b3290fd5 with no human approval. Converting back to draft did not dequeue it. Platform fact: objectstack-ai/objectstack#12200. The mechanism — hidden tool side effect + irreversible queue — will recur.
Scope
Make human review mechanically required for this repo's governed surface (2026-08-18 definition): AGENTS.md, CLAUDE.md, .claude/**, skills/**, docs/adr/**.
Candidate shapes — the implementer measures which is viable, does not assume:
.github/CODEOWNERS entries scoped to exactly the governed paths, plus the branch-protection "require review from Code Owners" setting. The settings half is a GitHub-UI change only the maintainer can make — if this shape is chosen, the PR half lands the CODEOWNERS file and the card then moves to pm:awaiting-maintainer naming the exact toggle.- A required status check that fails any PR touching governed paths unless an explicit human approval review is present.
Constraints:
- The door must not block the normal dev-PR merge queue for PRs that do not touch governed paths.
- The enforcement change itself touches governed/config surface — it lands as a draft PR for human merge, per the same rule it enforces.
- Named reader: the objectui execution seat that implements it; central triage routes the domain label.
- Sibling repos carry the same gap; mirroring is a separate triage/maintainer call once this repo's shape is proven — not part of this card.
