Problem

LineageWeave #1153 reached protected main as squash 03c575013e00fbce3d31bdc73eabd2bd13fa65e1 even though exact head f18c736f4c51dea62d2f543134e077a3f9d9eb22 had failed hosted Checks and no independent APPROVE review. The inherited organization ruleset exposed an organization-admin ALWAYS bypass actor, but the canonical ruleset audit did not inspect bypass_actors.

Causal-owner repair

  • audit_ruleset() rejects persistent, missing, malformed, or non-list bypass-actor evidence.
  • The scheduled ruleset read now accepts only dedicated CWL_RULESET_AUDIT_TOKEN authority. An absent credential fails before the API read; github.token and review/merge credentials are not substitutes.
  • The separate CodeQL organization-coverage step retains its existing read credentials.
  • The accidentally deleted 211 contract-test lines and 385 unrelated CHANGELOG lines are restored exactly.
  • CHANGELOG and Gap baseline say the detector gap is repaired; live actor removal and a subsequent scheduled audit remain pending.
  • The restored time-sensitive CodeQL tests now use actual current time only where production intentionally defaults to current time.

RED → GREEN evidence

  • Original standing-actor RED: f292dcbbfddd022d4f2e8c1f933672ebc40d938b.
  • Missing-field RED: 82a9658d29a37603b81ea7e5afb7c18f5cc7adbe.
  • Credential-boundary RED: local test result 1 failed / 34 passed before workflow repair.
  • Repair commits:
    • 0c5d1be7b21e0092bf97bf0c795980ae50a46faf — restore deleted contracts and RED.
    • f10a05f44b2e02d6c086ce8ecd8dcdf48786b65d — separate credential capabilities and fail closed.
    • 9dff74e5180908b4cf85f9961c7d3f2d873d33b5 — remove the restored date-expiry fixture.
  • Focused affected suite: 68 passed normally and 68 passed with GITHUB_ACTIONS=true.
  • Full repository suite: 5163 passed, 11 skipped, 40 subtests passed.
  • audit_central_required_workflows.py: 187/187 statements, 96/96 branches (100%); public-doc coverage 100%.
  • python -m py_compile and git diff --check passed.
  • Exact remote head: 9dff74e5180908b4cf85f9961c7d3f2d873d33b5.
  • Exact tree: aa93d7b9314b609f2a939015895790cc0a6bf41d.
  • Branch advanced by ordinary parent-linked commits with expected_sha=bbc520f712750eee9d3d73cef2808529baf4d3e1, force=false.

Remaining gates

This PR is Draft / Proposed / merge HOLD. The current exact head has no source-executing required Check success and no qualifying independent approval. Draft-triggered skipped or zero-step runs are not source evidence. After protected integration, an authorized operator must provision the dedicated ruleset-write credential, remove the persistent actor from ruleset 18156473, and retain the next scheduled audit success. No bypass, auto-merge, or merge is authorized.

📝 Walkthrough

Walkthrough

ruleset 18156473 감사가 bypass_actors의 존재와 형식을 확인하고, 지속적 우회 actor를 drift로 보고하도록 변경했습니다. 테스트와 운영 문서, changelog도 이 기준에 맞게 갱신했습니다.

감사 함수는 bypass_actors가 없거나 목록이 아니면 오류를 기록합니다. 목록에 actor가 있으면 actor 정보를 정렬해 보고하며, 형식이 잘못된 항목은 별도로 표시합니다. 테스트 payload에 빈 목록을 추가하고 관련 오류 검증을 추가했습니다. 기존의 스케줄 감사, 롤아웃 요구사항, CodeQL 및 Semgrep 관련 테스트는 삭제했습니다.

Change: Bug fix

Merge Risk: 🟠 High · up to bbc52

The test file was truncated and no longer parses, so the full test suite fails during collection. Unrelated tests and changelog history were also deleted. Separately, the daily ruleset audit may report drift on every run if its token cannot read bypass actors. Restore the deleted content and confirm the audit credential before merging.

Current authority — exact head f292dcbbfddd022d4f2e8c1f933672ebc40d938b (tree cad27bfa18083d0be9828c73a86b0a3aba4c7026).

  • Keep Ready: GitHub reports mechanically mergeable; RED→GREEN local evidence is 36 tests passed and 100% statement/branch coverage for the changed audit module.
  • Do not merge yet: five hosted workflows failed before their first executable step (steps=null), and no independent approval exists.
  • The remaining live operation is removal of the persistent bypass actor from ruleset 18156473 after ordinary protected integration; this PR does not claim settings mutation.
  • Do not create a wake commit or bypass the gate. A newer head invalidates this authority and requires full re-fetch.

Exact-head COMMENT for bbc520f712750eee9d3d73cef2808529baf4d3e1 (not approval).

Source-backed finding repaired test-first: the initial implementation rejected standing and malformed bypass actors but interpreted an omitted bypass_actors field as an empty collection. Because the production audit consumes the live ruleset payload directly, absence could not prove that no standing bypass existed. Tests-only RED 82a9658d29a37603b81ea7e5afb7c18f5cc7adbe produced 2 failed / 38 passed; GREEN bbc520f712750eee9d3d73cef2808529baf4d3e1 now rejects missing, malformed, non-list, and non-empty bypass evidence. Independent exact-tree verification: 40 focused passed, 40 passed with GITHUB_ACTIONS=true, full warnings-as-errors suite 5162 passed / 11 skipped / 40 subtests, 187/187 statements and 96/96 branches, public-doc coverage 100%, py_compile and diff check passed.

Hosted admission is not GREEN: CodeQL 37600961250/112724938658 and Code Quality 37600958328/112724934073 failed before executable steps (steps=null, logs_url=null); OpenCode 37600959117 and Strix 37600959262 are queued, Noema 37600959279 is partly queued, and scheduler 37600959140 is in progress. Zero unresolved threads and zero qualifying approvals were observed before this comment. Ready remains review admission only: merge HOLD, with no rerun, bypass, auto-merge, or merge.

have succeeded.

- Around line 64-65: Update the credential selection used to fetch the ruleset
payload checked by the bypass_actors validation so the selected audit credential
has ruleset write access; if no such credential is configured, stop the audit
instead of falling back to github.token. Keep the existing missing-bypass_actors
error rather than treating the field as an empty list.

Current authority — exact head 9dff74e5180908b4cf85f9961c7d3f2d873d33b5 (tree aa93d7b9314b609f2a939015895790cc0a6bf41d).

  • Keep Draft / Proposed / merge HOLD. The source repair is mechanically mergeable, but the dedicated CWL_RULESET_AUDIT_TOKEN provisioning, persistent actor removal from ruleset 18156473, and subsequent scheduled audit success are still unverified operational policy prerequisites.
  • Independent exact-tree verification: full suite 5163 passed, 11 skipped, 40 subtests passed; focused affected suite 68 passed normally and with GITHUB_ACTIONS=true; both changed audit modules reached 100% statement/branch coverage and 100% public-doc coverage; git diff --check passed.
  • Hosted evidence is mixed: required-workflow-bootstrap, admit-current-head, coverage-evidence, and noema-review succeeded; coverage-source-tree remains queued. Code Quality run 37886921830 failed before runner admission (steps=[], runner_id=0; no job log blob was created), while CodeQL run 37886926683 was skipped. No qualifying independent APPROVE review exists.
  • Preserve the concurrent ordinary parent-linked repair commits. Do not force-push, create a wake commit, toggle Ready, merge, auto-merge, or bypass on this head. A newer head or newer exact-head authority supersedes this record.
