Summary

RFC internal#219 Phase 4 (per ci.yml header comment) is overdue. Tonight 3 PRs merged with ci=failure on the head SHA (#594, #609, #592). Root cause: branch protection on molecule-core/main only requires Secret scan / Scan diff… + sop-tier-check / tier-check. The actual CI gates (Platform-Go, Canvas, E2E, Handlers-Postgres, etc.) are not in the required-checks list, AND every job in ci.yml is continue-on-error: true. So a real CI failure produces an aggregate state=failure on the commit, but no required check fails, so the merge button is enabled.

This is not a force-merge via admin-bypass: core-qa and core-devops are in engineers/qa/security teams (auth=Read), not owners. They satisfied the (weak) protection legitimately. The protection is the bug.

The fix is two coordinated changes that ship in this issue's PR: add the ci / all-required aggregator job + PATCH branch protection to require it. Sequencing matters — protection PATCH must land after the aggregator merges and runs at least once on main, otherwise PRs will be unmergeable until the next push to main.

Canonical reference

Port verbatim-then-adapted from molecule-controlplane/.gitea/workflows/ci.yml (same RFC §4 pattern; already in production there). Existing controlplane protection has "ci / all-required (pull_request)" in status_check_contexts and works.

Phase 4 — scope of this PR

Change 1: add `all-required` aggregator job to `.gitea/workflows/ci.yml`

all-required:
  # Sentinel aggregator job for branch protection. MUST be in
  # status_check_contexts on protected branches. Lists every job whose
  # red status should block merge. Uses `needs:` so the runner emits a
  # single status that resolves only after all listed jobs settle, and
  # `if: always()` so a failed dependency doesn't mask this as
  # "skipped" (which protection treats as pending forever).
  needs:
    - detect-changes
    - platform-go
    - canvas-nextjs
    - shellcheck
    - python-lint-test
    # (enumerate every job in ci.yml that should be required —
    # see RFC §4 "what counts as required" for the canonical list)
  if: always()
  runs-on: ubuntu-latest
  steps:
    - name: Aggregate
      run: |
        # Fail unless every listed `needs:` job has result == success
        # OR skipped (path-filter no-op).
        cat <<'EOF' | python3 -
        import json, os, sys
        results = json.loads(os.environ['NEEDS_JSON'])
        bad = {k:v['result'] for k,v in results.items()
               if v['result'] not in ('success','skipped')}
        if bad:
            print('FAIL:', bad); sys.exit(1)
        print('OK')
        EOF        
      env:
        NEEDS_JSON: ${{ toJSON(needs) }}

(Adapt the script style to whatever controlplane uses — port style preferred over reinvention.)

Change 2: PATCH branch protection on `main` AND `staging`

-- target state for both main and staging branches:
status_check_contexts := [
  "Secret scan / Scan diff for credential-shaped strings (pull_request)",
  "sop-tier-check / tier-check (pull_request)",
  "ci / all-required (pull_request)"
]

staging branch currently has no protection row at all — must be created in this PR using the same shape as main. Use the Gitea API POST/PATCH /repos/molecule-ai/molecule-core/branch_protections, not direct DB write, so it goes through the Gitea write path (audit trail + cache invalidation).

Sequencing requirement

Land Change 1 first (the aggregator job appears in main).
Push a tiny no-op to main to ensure ci / all-required runs at least once and Gitea has a recorded status context.
Land Change 2 (protection PATCH).

If you do them in one PR as separate commits, rebase carefully — protection PATCH must NOT be applied before the aggregator status has been observed by Gitea at least once.

Five-Axis review

This PR must pass Five-Axis review per feedback_pr_review_via_other_agents. Suggested reviewers:

core-security (RFC §6 risk: a misconfigured aggregator that always passes is worse than no aggregator)
core-devops (you own ci.yml; can do correctness lens but not the same-PR APPROVE — needs second pair of eyes)

Definition of done

ci / all-required aggregator job appears in ci.yml and emits a status on every PR
Verified: a deliberately-failing test (e.g. a one-line bad-go-syntax commit on a throwaway branch) makes ci / all-required red and the merge button disabled
main AND staging protection both list ci / all-required (pull_request) in required-checks
ci-required-drift.yml no longer exits 3 with "missing sentinel" (RFC §4 expected post-Phase-4 behavior)
No CI red on main after merge (verify aggregator catches transitive failures)
Five-Axis review passed (lens-ladder per feedback_multi_lens_review_caught_chained_defect)

Follow-ups (file as separate tier:high issues, not in this PR)

PR-2: flip continue-on-error: true → false on the jobs already passing reliably on main (RFC §1 Phase 4). Needs CI-history analysis to pick which jobs are stable enough. Don't flip a flaky job — diagnose flake first.
PR-4: same protection PATCH on operator-config/main (currently only secret-scan + shellcheck, no block_on_rejected_reviews) and any other repos with weak required-checks (molecule-internal, molecule-dev-department, etc.). Run ci-required-drift org-wide audit first.
PR-5: tighten audit-force-merge.yml to OPEN a tier:high [incident.force-merge] issue in addition to emitting Loki, so the incident is visible without grafana. Backfill: open audit issues for tonight's #594, #609, #592 retroactively (one-off script).

Out of scope

Permission revocation: persona perms are appropriate (Read on engineers team). Don't downgrade.
The audit-force-merge.yml and ci-required-drift.yml workflows themselves — these already exist and are working as designed; PR-5 only extends audit-force-merge.
Backporting protection PATCH to other repos — that's PR-4, separate fan-out.

Telemetry

After this PR ships, set up a Loki alert on {event_type="incident.force_merge"} so future force-merges page on-call (the audit workflow already emits the JSON, just needs the alert glue).

Cross-links

RFC source: internal#219 §4 (jobs ↔ protection) + §6 (audit env ↔ protection)
Reference port: molecule-controlplane (same pattern, already shipped)
Memory: feedback_never_admin_merge_bypass, feedback_path_filtered_workflow_cant_be_required, feedback_pr_review_via_other_agents
Tonight's incidents: #594 (23:33Z, merger TBD), #609 (00:13Z by core-qa), #592 (00:32Z by core-devops) — all merged red. Use as smoke-test cases when verifying the fix.

[triage-agent] Hourly triage ~03:35Z: assigned to core-devops. PR #630 (fix ci-required-drift handles 403/404 on protection endpoint) is open — this addresses one Phase 4 fix. qa-review and security-review checks are failing on every open PR (issue #631, tier:high) — this is a separate but related CI failure blocking ALL PR merges. Awaiting core-devops resolution.

Hongming GO via orchestrator — Phase 4 dispatch unblocked

Status: Hongming has explicitly approved this work in chat (2026-05-12). Tonight's events validate the urgency:

4 PRs (#519/#641/#646/#647) sat unmergeable for 1h+ tonight due to Gitea status-emitter null states on the current required-check contexts (Secret scan + sop-tier-check)
Both were emitting state=null rather than success, so Gitea concluded "Not all required status checks successful" even though the workflows ran clean
#647 eventually auto-merged after 30+ min cache-lag; #519/#641/#646 are still stuck

This issue is the proper-fix.

Concrete dispatch — canonical port from controlplane

Reference (already in production):

molecule-controlplane/.gitea/workflows/ci.yml — has the working ci / all-required aggregator job
molecule-controlplane main branch protection — already has "ci / all-required (pull_request)" in status_check_contexts (verified via API tonight)

Sequencing (this matters):

Change 1 first: Add the all-required aggregator job to .gitea/workflows/ci.yml in molecule-core. Port verbatim from controlplane, adapt needs: list to molecule-core's actual jobs (detect-changes, platform-go, canvas-nextjs, shellcheck, python-lint-test, e2e-staging-canvas, handlers-postgres-integration, e2e-api-smoke, runtime-pr-built-compatibility). Use if: always() so failed deps don't mask as "skipped".
Merge Change 1 + push a tiny no-op to main — ensures Gitea has at least one recorded status context emission for ci / all-required.
Change 2: PATCH branch protection on main AND staging via Gitea API:
- target status_check_contexts: ["Secret scan / Scan diff for credential-shaped strings (pull_request)", "ci / all-required (pull_request)"]
- DROP sop-tier-check / tier-check (pull_request) (tangential + noisy)
- staging branch currently has no protection row at all — create one matching main's shape

Verification post-merge:

A deliberately-failing test PR makes ci / all-required red AND merge button disabled
ci-required-drift.yml no longer exits 3 with "missing sentinel"
The 3 stuck PRs (#519, #641, #646) become merge-eligible (after their rebase recomputes against new main)

Five-Axis review required before merge (per feedback_pr_review_via_other_agents). Reviewers: core-security (RFC §6 risk) + a second pair of eyes (not same-PR author).

Unblockers met. Please proceed.
