Execution: activate exact-head repository governance (PR #899)

[groupthinking]

Parent program

Progresses #898. This focused issue owns repository-governance activation only; #899 must close this issue, not #898.

Current state — BLOCKED BY LEGACY PROVENANCE

• Canonical PR/branch: ci: establish autonomous repository governance #899 / agent/autonomous-repository-governance
• Exact head: cbae9110cfd7b6b89b2686bd9fd705ea4e649778
• PR state: draft, open, mergeable, unmerged
• Code/review state: exact-head application and security workflows passed; 12/12 review threads resolved
• Truth gate: failed at exact-head run 29819304441
• Proven cause: this issue was created at 2026-07-21T03:09:15Z, after PR ci: establish autonomous repository governance #899 was created at 2026-07-20T22:54:15Z, and no pre-dispatch intent snapshot exists
• Competing implementation PRs: none

Objective

Activate the repository-owned PR contract and non-destructive reconciliation loop implemented by #899 without weakening the independent agent-completion trust policy.

Focused test paths

• tests/unit/test_pr_governance_workflow.py
• tests/unit/test_repository_reconciliation_workflow.py

Acceptance criteria

• Publish PR Governance against pull_request.head.sha.
• Use the minimum additional checks: write permission.
• Keep draft PRs neutral/deferred.
• Reject missing, default, placeholder, and HTML-comment-only evidence.
• Validate one real open canonical issue and detect competing implementation PRs.
• Catalog and audit both workflows.
• Cover governance and reconciliation behavior with focused tests.
• Resolve all review findings on the exact current head.
• Keep ci: establish autonomous repository governance #899 draft after the failed exact-head truth gate was discovered.
• Satisfy the independent agent-completion trust policy.
• Obtain final human approval.

Exact-head evidence

• CI, Coverage, CodeQL, Security Scan, Secret Scan, and Dependency Review passed on cbae9110cfd7b6b89b2686bd9fd705ea4e649778.
• E2E was repository-skipped because no deployed application surface changed.
• The exact-head Vercel preview was canceled; the workflow/docs/test-only diff does not exercise the deployed application.
• Truth-gate run 29819304441 validates the repaired identity projection (groupthinking, issue 905, run eventrelay-governance-repair-20260721-0215z) and now fails on the real collection error: missing_intent_snapshot.
• Review dispatch receipt: adding copilot-rabbit was accepted at 2026-07-21T09:41:52Z; the standard reviewer request was rejected with GitHub 422 because copilot-pull-request-reviewer is not a repository collaborator. No review artifact exists yet.

Next executable transition

1. Wait for the accepted current-head Copilot review trigger; patch ci: establish autonomous repository governance #899 only if it opens a valid finding.
2. Keep ci: establish autonomous repository governance #899 draft because exact-head run 29819304441 proves missing_intent_snapshot.
3. An authorized repository/security owner must choose exactly one policy-preserving exit:
   • authorize a replacement PR created only after a compliant frozen intent snapshot, then close ci: establish autonomous repository governance #899 as superseded; or
   • grant an explicit, documented legacy-provenance exception for ci: establish autonomous repository governance #899.
4. Do not merge ci: establish autonomous repository governance #899 or weaken the gate until that choice is recorded.

The controller is not authorized to create a competing implementation, fabricate a historical snapshot, impersonate a trusted agent, or weaken the security policy.

Competing proposal quarantine — 2026-07-22T13:27:00Z

• PR #933 at exact head 8b1d8fbbaf2dfc0cae060e66d6a72d711e0c7738 proposes returning a neutral Check when the trust App is unprovisioned and all allowlists are empty.
• This is a security-policy exception to the current fail-closed contract, not a routine CI repair.
• [DRAFT EVIDENCE] neutral enforcement proposal while trust App is unprovisioned #933 has no focused issue, valid agent-lock manifest, or provider run ID. Exact-head truth-gate run 29921176550 proves invalid_payload.
• Vercel review identifies the protected-policy contradiction: the policy notes still say empty allowlists intentionally block.
• Controller action: [DRAFT EVIDENCE] neutral enforcement proposal while trust App is unprovisioned #933 is preserved draft and labeled evidence-only/duplicate; no workflows were approved and no code was ported.
• Canonical implementation remains this issue / ci: establish autonomous repository governance #899. Active competing implementations return to zero after quarantine.
• Next action: repository/security owner must explicitly accept or reject neutral-until-provisioned semantics. If accepted, apply the authorized delta on ci: establish autonomous repository governance #899 and verify a new exact head; otherwise leave ci: establish autonomous repository governance #899's fail-closed policy intact.

Provenance-bypass proposal quarantine — 2026-07-22T15:14:44Z

• PR #934 at exact head 4a0a184fa7fdcf56ebdba87a2c4c57c0a1a8bdab proposes inferring identity from the PR author, extracting run identity from mutable PR text, skipping manifest mismatch checks without a manifest, and synthesizing artifact_ready from PR creation metadata.
• This would allow the PR under verification to self-certify provenance. It is an unauthorized security-policy weakening.
• [DRAFT EVIDENCE] provenance-bypass proposal for issue-less agent PRs #934 has no focused issue, valid manifest, provider run ID, or explicit artifact event. Truth-gate run 29932261276 correctly proves invalid_payload.
• Controller action: preserved [DRAFT EVIDENCE] provenance-bypass proposal for issue-less agent PRs #934 as draft evidence and labeled it noncanonical/duplicate; no workflows were approved and no code was ported.
• Canonical implementation remains this issue / ci: establish autonomous repository governance #899. Active competing implementations return to zero after quarantine.
• Next action: leave the explicit, independently published provenance contract intact. Any authorized compatibility change belongs on ci: establish autonomous repository governance #899 and must retain fail-closed mismatch behavior.

Duplicate security-proposal sweep — 2026-07-22T16:10:04Z

• [DRAFT EVIDENCE] provenance-bypass proposal for issue-less agent PRs #934 advanced externally to exact head e017184227d8b2fb6ecd6b592b16935025c67b6d and was marked ready; the controller returned it to draft. CI and Coverage fail and four review threads remain unresolved.
• #935 28d98d662c68763332ec483f6e042a8367f0fbca and #938 b534a80df7e92a793d587d350d3200f08e27e91b independently repeat the unapproved neutral-enforcement change.
• Both proposals were labeled security/ci/cd/duplicate, kept draft, and marked evidence-only. Neither has authority to replace ci: establish autonomous repository governance #899.
• Canonical unit remains Execution: activate exact-head repository governance (PR #899) #905/ci: establish autonomous repository governance #899 at cbae9110cfd7b6b89b2686bd9fd705ea4e649778; active competing implementations are zero after quarantine.

• [DRAFT EVIDENCE] neutral enforcement proposal while trust App is unprovisioned #933 advanced to exact head cb8a8dee263b0d8cef4fa6d4479677a026c11b44, expanded to 11 files (+786/-789), and was marked ready.
• Controller returned it to draft. No exact-head workflow runs are currently available and five review threads remain unresolved.
• It remains noncanonical evidence; Execution: activate exact-head repository governance (PR #899) #905/ci: establish autonomous repository governance #899 retains sole implementation authority.

#941 exact-head disposition — 2026-07-22T17:15:16Z

• PR #941 remains draft security evidence at exact head 95257c797845c8205d1e1a06611d685828973838; it proposes unnecessary CodeQL contents: write and actions: write permissions without a focused issue or least-privilege proof.
• CI 29936964766, Coverage 29936965182, CodeQL 29936965098, Security 29936964696, Secret Scan 29936964595, and Dependency Review 29936965052 pass; E2E is skipped.
• Copilot and Vercel independently reviewed the exact head and confirmed the write escalation lacks demonstrated need; zero review threads remain.
• Green checks do not authorize broader permissions. Canonical governance remains Execution: activate exact-head repository governance (PR #899) #905/ci: establish autonomous repository governance #899 at cbae9110cfd7b6b89b2686bd9fd705ea4e649778.
