Purpose

Repair two central CodeQL contract defects without weakening the SARIF gate:

  1. replace bare hostname-substring assertions in the organization commercial-readiness egress contract with exact allowlist membership;
  2. derive fallback CodeQL verdict from the Enforce CodeQL Medium+ SARIF gate step so a clean scan is not inverted by a later wake-only HTTP 403.

Current exact is 2acb72681a9acd146eb938b8d97c4d67d9ae7e9c, a normal one-commit descendant of 7d496d626d2a7f7495591befc0095f9acff2f937, on protected central main@a9c6477d326b84411f492ba4cac29f52deebcac3. Keep Draft while exact-head required workflows remain nonterminal.

Verified source delta

  • .github/workflows/codeql-pr.yml: when dispatch status publication is unavailable, the receiver inspects the matching dispatch job's Enforce CodeQL Medium+ SARIF gate step first. Gate SUCCESS yields success even if a later Wake exact CodeQL required job step fails; gate failure/cancel/skip yields failure. A focused regression covers the wake-only failure case.
  • tests/test_organization_commercial_readiness_loop_receipt_contract.py: removes the bare "endpoint" in source hostname pattern that produced Medium+ py/incomplete-url-substring-sanitization and instead parses allowed-endpoints before checking exact endpoint membership.
  • Review repair 2acb726...: bounds _harden_runner_allowed_endpoints to the folded YAML scalar's more-indented lines and adds a regression proving a later workflow step (- name: Checkout exact trusted coordinator source) is not returned as an endpoint. This resolves the prior parser-boundary Major without changing SARIF severity, query filters, runner selectors, provider/model policy, or unrelated workflow behavior.

The prior parser review thread is resolved on this source. Historical local verification on predecessor exacts does not transfer to 2acb726....

Current exact-head acceptance

Fresh required workflows exist only for 2acb726... and are currently nonterminal: SAST Semgrep 35203787993, Agent Review Runtime Quality CI 35203788018, CodeQL PR 35203787985, Security Scan 35203787998, and Python Security 35203788016 are queued. No aggregate GREEN, approval, merge, or downstream reconciliation is claimed yet.

Downstream authority

Queue-health integration #2201 currently fails its python CodeQL shard on inherited central source and retains producer artifact 10472538346 / SHA-256 4e0ad775c0f625f957008a370a4032bff60bb2a3ad953d621bcf93b5b2a947c9. Correct sequencing is #2234 2acb726... exact-head terminal acceptance → normal protected integration/reconciliation of dependent central owners such as #2201 → fresh downstream evidence. Do not source-copy this repair into queue-health or leaf repositories and do not blind-rerun inherited vulnerable source.

Issue #2133 (GHAS differential-analysis configuration identity) remains outside this PR and stays coordinated with the #2106/#2040 handler stack.

No self-approval, admin bypass, force update, destructive rebase, synthetic status, gate/query suppression, or predecessor-evidence transfer.

Summary by CodeRabbit

  • 버그 수정

    • CodeQL 보안 검사 결과가 특정 보조 단계의 실패로 잘못 판정되지 않도록 결과 판정이 개선되었습니다.
    • SARIF 보안 게이트가 성공한 경우, 관련 보조 작업이 실패하거나 취소되어도 검사 결과가 올바르게 성공으로 처리됩니다.
    • 허용된 엔드포인트 목록을 읽을 때 후속 YAML 단계가 잘못 포함되지 않도록 처리 경계가 개선되었습니다.
  • 테스트

    • CodeQL 결과 판정 및 엔드포인트 목록 처리에 대한 검증이 강화되었습니다.

The repaired SARIF gate blocked every PR on a contract-test substring heuristic (#2208); parse harden-runner allowlist membership instead. The required shard now reads the dispatch gate step outcome so a clean scan is not reported as failure when only the wake step fails (#2141).

📝 Walkthrough

Walkthrough

CodeQL verdict가 전체 job 결론보다 SARIF 게이트 결과를 우선 사용하도록 변경되었다. 관련 계약 테스트가 추가되었다. 허용 엔드포인트 검증은 YAML 블록을 파싱한 뒤 필수 항목을 확인하도록 변경되었다.

CodeQL SARIF 게이트 판정

Layer / File(s) Summary
SARIF 게이트 우선 판정 및 계약 테스트
.github/workflows/codeql-pr.yml, tests/test_codeql_pr_workflow_contract.py
완료된 dispatch job에서 Enforce CodeQL Medium+ SARIF gate 단계의 결과를 우선 사용한다. 게이트가 성공하면 성공 verdict를 반환한다. 게이트가 실패·취소·건너뜀 상태이면 실패 verdict를 반환한다. 게이트 결과가 없을 때는 전체 job이 성공한 경우에만 성공 verdict를 반환한다. wake 단계만 실패한 경우에도 성공 verdict를 반환하는 테스트를 추가했다.

허용 엔드포인트 계약 검증

Layer / File(s) Summary
허용 엔드포인트 파싱 및 필수 항목 검증
tests/test_organization_commercial_readiness_loop_receipt_contract.py
allowed-endpoints 블록을 파싱하는 헬퍼를 추가했다. 블록이 없으면 검증에 실패한다. 파싱된 집합에 결과 수신기, Actions 와일드카드, Azure Blob 와일드카드가 포함되는지 확인한다. 후속 단계 이름이 엔드포인트로 포함되지 않는지도 확인한다.

Merge Risk: 🟡 Moderate · up to 7d496

The egress allowlist regression test can pass after an endpoint is removed if the same value appears later in the workflow. Restrict parsing to the YAML block before merging.
