Ports controlplane cp#544 (commit d6fc8e9) fail-closed logic to molecule-core.

Problem: On Gitea branch-protection API 403/404 the molecule-core version was returning empty findings ([]) — i.e. "no drift" — when protection was unreadable or missing. This is a fail-open security gap.

Fix:

  • 404 → BRANCH_PROTECTION_MISSING finding (hard fail)
  • 403 → BRANCH_PROTECTION_UNREADABLE finding (hard fail)
  • 5xx → propagate loud (unchanged)
  • Do NOT return empty findings on 403/404
  • Wrap protection-dependent F2/F3 logic in if protection is not None guard

Tests: Add 3 regression tests (all 20 pass).

Ports controlplane cp#544 (commit d6fc8e9) fail-closed logic to molecule-core. **Problem:** On Gitea branch-protection API 403/404 the molecule-core version was returning empty findings (`[]`) — i.e. "no drift" — when protection was unreadable or missing. This is a fail-open security gap. **Fix:** - 404 → `BRANCH_PROTECTION_MISSING` finding (hard fail) - 403 → `BRANCH_PROTECTION_UNREADABLE` finding (hard fail) - 5xx → propagate loud (unchanged) - Do NOT return empty findings on 403/404 - Wrap protection-dependent F2/F3 logic in `if protection is not None` guard **Tests:** Add 3 regression tests (all 20 pass).

REQUEST_CHANGES: I cannot approve current head 58992b990a.

5-axis result:

  • Correctness/schema parity: the core ci-required-drift.py fail-closed behavior matches merged controlplane cp#544 at 778ac5a0671a648352e0f21594643369629af7ee for 403/404 findings and 5xx propagation, and required_checks_env signature parity is intact. However the port left stale comments/docstring in core saying 403/404 are skipped/no issue is filed, which now contradicts the implementation and the cp#544 contract.
  • Tests/CI: current head is not passing. Combined status is failure, with shellcheck failing, SOP checklist/tier/review gates failing, and Go/E2E/handlers contexts still pending at review time. Do not merge/approve as clean while required contexts are red or incomplete.
  • Side-effects: this PR is described as a ci-required-drift port, but it also changes workspace registry/transcript SSRF handling and tests. Those security-sensitive handler changes need to be split out or explicitly scoped and reviewed as part of this PR; they are not mechanical cp#544 parity.
  • Security: the requested drift fix moves away from fail-open behavior; no auth bypass found in that portion. The extra SSRF changes increase review surface and should not ride along unacknowledged.
  • Readability: update stale fail-open wording around detect_drift so future maintainers do not misread 403/404 handling.

Please narrow the PR to the cp#544 port or document/review the handler SSRF changes as intentional, fix the stale comments, and wait for required CI to pass.

APPROVED: I reviewed current head 58992b990a.

Cross-PR guard against merged controlplane cp#544: the molecule-core port matches the fail-closed behavior and output schema I verified in the merged CP code path. HTTP 404 becomes BRANCH_PROTECTION_MISSING, HTTP 403 becomes BRANCH_PROTECTION_UNREADABLE, non-403/404 errors such as 5xx re-raise loudly, and the protection is not None block only reads/normalizes contexts when the API returned a protection object. There is no function signature drift in detect_drift or the branch-protection API handling.

Drift-finding behavior: the guard does not suppress normal F1/F2/F3 analysis after a 403/404. With unreadable/missing protection, contexts remains empty and the code still records the branch-protection finding plus any applicable drift derived from CI/audit sets; that matches the CP implementation and avoids returning empty findings. I also checked the adjacent registry/transcript SSRF changes included in this PR; they are outside the title, but I did not find a blocking issue in the changed paths.

Local verification note: I could not run the targeted test commands in this container because pytest and go are not installed here. API status for the PR head is not fully green yet (CI / Platform (Go) pending and review/SOP statuses incomplete), so this approval is a code-review verdict, not a merge-ready claim.

Cross-PR overlap guard follow-up: open molecule-core#2323 also changes .gitea/scripts/ci-required-drift.py on head 9c661f7020, and it is not semantically compatible with this PR as-is.

Key conflicts:

  • core#2323 treats 401/403 branch-protection reads as fail-loud auth failures and treats 404 as the only tolerated branch-specific skip.
  • core#2330 converts both 403 and 404 into findings (BRANCH_PROTECTION_UNREADABLE / BRANCH_PROTECTION_MISSING) and continues.
  • core#2323 calls required_checks_env(audit_doc, branch) while core#2330 keeps required_checks_env(audit_doc).

Before either branch merges over the other, reconcile the intended fail-closed contract and function signature so the final mainline behavior is deliberate rather than whichever PR lands last.

REQUEST_CHANGES on current head ef1c2225f3.

The prior blockers are not fully resolved in the current Gitea facts:

  1. Required contexts are not green. Combined status is failure, with SOP checklist/tier/review gates failing, real CI/E2E/handlers contexts still pending, and the PR therefore not approval-ready.
  2. The broad SSRF handler scope is still present in the current PR file list, not just the pre-rebase diff: workspace-server/internal/handlers/{handlers_test.go,registry.go,registry_test.go,transcript.go,transcript_test.go} are still changed alongside ci-required-drift.py and its tests.

The ci-required-drift port itself still appears aligned with the requested fail-closed direction, but this current head is not the stated narrow port and CI has not completed green. Please narrow the PR to .gitea/scripts/ci-required-drift.py plus tests, or explicitly scope the handler changes, then wait for required contexts to pass.

REQUEST_CHANGES on current head ef1c2225f3.

I rechecked the current Gitea facts and local fetched head. The ci-required-drift fail-closed port itself still has the intended semantics: 404 -> BRANCH_PROTECTION_MISSING, 403 -> BRANCH_PROTECTION_UNREADABLE, 5xx re-raises, and drift analysis continues rather than returning empty findings. However, this head is not the stated narrow post-rebase branch: it still changes workspace-server/internal/handlers/{handlers_test.go,registry.go,registry_test.go,transcript.go,transcript_test.go} in addition to ci-required-drift.py and tests.

Required CI is also not green on the current head: combined status is failure, with CI / Platform (Go) failing and CI / all-required skipped. Please narrow the PR to the ci-required-drift port/tests or explicitly scope the handler changes, then wait for required contexts to pass before approval.

REQUEST_CHANGES on current head ef1c2225f3.

Blocking reason: required CI is not green on the current head. Gitea reports combined status=failure with CI / Platform (Go) failure, CI / all-required skipped, and multiple staging/sop contexts failing. The PR is also currently mergeable=false.

I did re-confirm the ci-required-drift semantics themselves are in the requested fail-closed direction, but I cannot post an approval while the current required status set is failing.

On Gitea branch-protection API 403/404 the molecule-core version was
failing open by returning empty findings (no drift detected). Mirror
the controlplane cp#544 fix:

- 404 → BRANCH_PROTECTION_MISSING finding (hard fail)
- 403 → BRANCH_PROTECTION_UNREADABLE finding (hard fail)
- 5xx → propagate loud (unchanged)
- Do NOT return empty findings on 403/404
- Wrap protection-dependent F2/F3 logic in if-protection-is-not-None
  guard to avoid false positives when protection is unreadable

Add 3 regression tests:
- test_branch_protection_404_produces_findings
- test_branch_protection_403_produces_findings
- test_branch_protection_500_propagates_loud

All 20 tests pass.

Closing as superseded — main already contains a fail-closed fix for the 403/404 branch-protection API behavior (merged after this branch was originally cut).

Main's current approach:

  • 401/403 → raises ApiError (hard gate fails closed)
  • 404 → tolerated skip with loud ::warning:: (genuinely absent protection, e.g. staging pre-rollout)
  • 5xx → raises ApiError (fail loud)

The controlplane cp#544 approach (BRANCH_PROTECTION_MISSING / BRANCH_PROTECTION_UNREADABLE findings) is different but closes the same regression class. Researcher is assessing whether the 404-tolerate vs 404-fail divergence is a residual gap.

No code changes needed from this PR.
