Why and what changed

main still has no effective required CI statuses despite the merged ruleset payload. Add a read-only verifier that compares active GitHub rules with that payload and writes JSON evidence, failing on missing or wrong-app checks, non-strict policy, missing human protections, hidden/configured CI bypasses, API failures, and rules changing during inspection. Document a safe administrator activation handoff and the controlled-PR evidence needed afterward.

This is the repository-side handoff for AIC-1911. It does not activate repository settings, establish controlled-PR enforcement evidence, close the issue, or remove the trusted-copy Full CI backstop.

Review map

  • Risk level: medium (CI policy verification; no product behavior change).
  • Start with scripts/check_required_main_checks.py, then the required-checks section of docs/ci.md.
  • Public or serialized contract changed: new local JSON evidence report and exit status only.
  • Compatibility or rollback concern: Python 3.11+ and authenticated gh are required. Hidden bypass configuration deliberately requires administrator read access. CI adds the verifier regression suite to the existing policy job.

Evidence

  • Tests: python -m pytest -c pytest.ini tests/test_ci_workflow_contracts.py tests/test_ci_qualification.py tests/test_release_fpe.py tests/test_required_main_checks.py -q -p no:cacheprovider: 321 passed on Python 3.12 with bundled Node on PATH. All 30 verifier cases passed on Python 3.11 too. Ruff lint/format, generated ownership coverage (100%), Markdown destinations, SPDX check, and git diff --check passed.
  • Live read-only smoke: exits 1 and names all three absent required contexts on September 17, 2026; existing review protections remain visible. No settings were changed.
  • Fast CI: direct PR run 35297058680 and trusted-copy run 35297471616 passed on a82e373ca1306119bd35648059e72ad2a01753c0; DCO and codeowners also passed.
  • Full CI: run 35297471838 is still pending on a82e373ca1306119bd35648059e72ad2a01753c0 after normal maintainer admission. The trusted copy matches the PR head. Review readiness is not yet established.
  • CodeRabbit reviewed commit: a82e373ca1306119bd35648059e72ad2a01753c0; substantive incremental review completed with no actionable comments. Both initial findings are fixed and resolved.
  • Codex reviewed commit: a82e373ca1306119bd35648059e72ad2a01753c0 freshly reviewed after publication; no remaining actionable findings.
  • Negative or boundary cases: missing contexts, wrong app binding, relaxed currency, missing review/branch protections, bypasses, unavailable/malformed API responses, settings changes, saved failure evidence, and nonzero exit status.
  • Expected-value derivation: independent test assertion pins all three intended context names and GitHub Actions app 15368; controlled PR observations remain an administrator follow-up.
  • Before/after output: configuration evidence now explicitly distinguishes failure from verified active settings; neither result claims PR merge readiness.

Modeling or data provenance

N/A. Synthetic API fixtures test configuration verification, not live enforcement.

Tracking

  • Related issue: AIC-1911; administrator activation and controlled-PR proof remain outstanding.

  • No consumers of the new verifier or required_main_checks were found. [::ai-dynamo/dynamo::]
  • The relevant check names are the codeowners workflow/job and the aggregate pre-merge-status-check; these should not be confused with individual workflow steps. .github/workflows/codeowners.yml:1,23, .github/workflows/pre-merge.yml:73-76 [::ai-dynamo/dynamo::]

📝 Summary

Risk level: High.

Human attention

  1. Confirm that the verifier covers all active rulesets that can affect main, not only rulesets returned through required status checks.
  2. Confirm that hidden or malformed bypass data fails closed without misleading evidence.
  3. Confirm the activation procedure and controlled-PR evidence requirements against live repository settings.

Changed behavior and contracts

  • Adds a read-only verifier for active main branch protections.
  • Validates app-bound checks, strict policies, review protections, branch protections, enforcement, and bypass actors.
  • Rechecks rulesets during inspection and reports configuration changes.
  • Writes JSON evidence to stdout and optionally to a file.
  • Returns failure when verification or evidence handling fails.
  • Adds regression tests and runs them under Python 3.11 and Python 3.12 in CI.
  • Adds test ownership and documents activation and controlled-PR evidence steps.
  • Does not modify repository settings or remove the trusted-copy Full CI backstop.

Evidence supplied

  • The verifier exposes github_api, payload validation, rule verification, repository inspection, and CLI entry points.
  • The implementation reads referenced rulesets, checks active enforcement, rejects bypass actors or hidden bypass data, and rechecks configuration changes.
  • CI invokes the required test suite and runs the verifier tests under Python 3.11.
  • The test suite covers weakened policies, bypass actors, malformed responses, API failures, pagination, CLI exit codes, and saved evidence.

Evidence still missing

  • No test execution result is supplied.
  • No current review findings or severity counts are supplied.
  • No live GitHub evidence report is supplied.
  • No controlled-PR enforcement evidence is supplied.
  • Merge readiness is not established.

Explanation

The new --repository CLI input is documented and implemented, but its non-default path is not tested. main() passes args.repository to inspect_repository() (scripts/check_required_main_checks.py:150-154), while the CLI test supplies only --output and replaces inspect_repository with a lambda that ignores the repository value (tests/test_required_main_checks.py:157-165). Direct tests use owner/repo, but they do not verify CLI parsing or propagation. This leaves a changed public input without an end-to-end consumer test.

Resolution

Add a CLI test that sets sys.argv to include a non-default --repository, captures the argument received by a monkeypatched inspect_repository, and asserts that the value is propagated. Also retain the success and failure JSON/exit assertions for that invocation.

configuration_verified true. Treat any changed detail, including a newly added
