ci: stop draft PR jobs from occupying runners

[seonghobae]

Scope

Wardnet-owned CI/Fuzz should not consume a local runner while a PR is Draft, but state-only transitions must not be mistaken for source supersession. This lane therefore keeps the existing Rust/fuzz validation surface while:

• guarding Draft PR jobs;
• using synchronize as the only cancel-in-progress source-supersession event;
• keeping reopened / ready_for_review validation in run-specific groups;
• using immutable repository-scoped wardnet-ci / wardnet-fuzz concurrency prefixes rather than mutable workflow display names; and
• binding both PR workflows to the exact source head ${{ github.event.pull_request.head.sha || github.sha }} with explicit post-checkout SHA verification.

Organization-owned Security/SAST/CodeQL/OpenCode/Strix/Noema/merge scheduling remains in ContextualWisdomLab/.github. This PR does not copy or weaken central workflows.

TDD / causal lineage

RED fbbccaadded691d7ce048f1ed9fe50307ab4e386 requires the bounded concurrency and Draft contract. CI/Fuzz implementations fa7c95eccc6b1319109dcd2372040b67bbac6a3c / 81b9048d75332367d13cdb9dd939f751599e48b0 implement it; 95360a0261d9e5f5718fc434a13237d0abda260f and eda2decf22cf2bead5c56ea7d9bf1e59638bcdf3 retain the state/head-supersession rationale and reviewed ICSE/arXiv evidence.

Evidence-integrity review then found default actions/checkout could execute GitHub's synthetic merge ref while this repository requires source-head proof. RED 51660b9400e5c8ef150f39b8d12500d1f1532528 requires explicit source-head checkout and equality assertions; GREEN 3247fd7ce14bb8c60bbc2a4ac8d2bfb9a67629af and 24bbd737ea554db4a5dce94326025daf0e3d76ab apply that contract to CI and Fuzz. CI 34048417184 on 24bbd737... acquired ubuntu-24.04, proved checkout identity, and failed only on rustfmt layout.

A temporary self-modifying repair at 271ab6a402348536513b7dc848248b601b03128f was rejected before use because it lacked a Draft guard, used an actionlint-invalid runner label, and executed PR workspace code with contents: write. The observed rustfmt-only correction was applied directly in a50346b371f5c22328c6de68d8e894b902cc5ece; exact current e00d61c994d3b1c2b7923bb1b781c1e06d32aae4 removes that unsafe workflow. Current diff is again limited to the five intended workflow/test/doctoring/research paths. No force push, destructive rebase, write-token PR-code execution or gate weakening is retained.

Exact current evidence — 2026-09-07 KST

Protected/default base remains main@a52ccd0a24a727d9349bb32def7713882d8cad1e; exact head remains e00d61c994d3b1c2b7923bb1b781c1e06d32aae4 and is mechanically mergeable.

Without source churn, the previously queued repository/security lanes have now executed:

• CI 34055794089: SUCCESS;
• Fuzz 34055793922: SUCCESS;
• Security Scan 34055793976: SUCCESS;
• SAST Semgrep 34055793970: SUCCESS.

CodeQL PR 34055793933 remains failure only at delegated terminal-verdict enforcement. Its actions job 101552071393 acquired ubuntu-24.04, successfully requested a current-head dispatch for exact e00d61c..., then failed closed with VERDICT_STATE=pending and the canonical contract message that the dispatch workflow must publish an authenticated terminal verdict and rerun this exact failed job. Fresh commit-status inventory still has no codeql-dispatch/actions verdict. This is no longer a Wardnet runner-acquisition defect; .github#712 comment 5562188970 records the narrowed producer/identity/settings acceptance. Do not mutate this clean source head or broad-rerun predecessor jobs to manufacture that verdict.

All current inline review findings from the rejected temporary workflow are resolved/outdated. Review/status providers that are rate-limited or skip for billing are not promoted to independent approval or semantic security evidence.

Merge boundary

Live organization ruleset 18156473 still has the structurally incompatible solo-maintainer generic approval count and routine OrganizationAdmin bypass tracked by .github#772. Self-approval, model/bot-as-human approval and routine/implicit administrator bypass are forbidden. The guarded chicken-and-egg exception does not apply to an ordinary delegated CodeQL wait.

Merge only through the ordinary protected path after the unchanged exact head has an authenticated terminal current-head CodeQL verdict, zero valid unresolved findings/threads, fresh candidate-base compatibility, and every then-live deterministic/security/SAST/coverage/package/SBOM/provenance/governance gate is terminal-valid. PR #130 remains the sole writer for docs/product-technical-gap-baseline.md; this lane hands evidence there rather than editing the ledger.

📝 Walkthrough

Walkthrough

CI 및 fuzz 워크플로의 pull request 이벤트와 동시성 그룹을 조정했습니다. synchronize에서만 이전 실행을 취소합니다. draft pull request의 작업 실행을 제한합니다. checkout 커밋 검증과 계약 테스트를 갱신했습니다. 포맷 복구용 일회성 워크플로를 추가했습니다.

Changes

워크플로 실행 제어

Layer / File(s)	Summary
이벤트 및 동시성 그룹 설정 .github/workflows/ci.yml, .github/workflows/fuzz.yml	converted_to_draft와 closed 이벤트를 제거했습니다. opened와 synchronize만 pull request 번호 기반 그룹을 공유합니다. synchronize에서만 진행 중 실행을 취소합니다.
작업 조건 및 checkout 계약 검증 .github/workflows/ci.yml, .github/workflows/fuzz.yml, tests/workflow_queue_contract.rs	draft pull request에서 rust 및 fuzz 작업을 건너뜁니다. 두 워크플로가 pull request head SHA 또는 push SHA를 checkout하고 실제 커밋을 검증하는지 테스트합니다. fuzz 경로 필터도 검증합니다.
동시성 정책 문서화 docs/doctoring/ci-queue-concurrency.md	이벤트별 동시성 그룹, 취소 조건, draft 및 상태 전환 처리, 현재 head의 터미널 증거 요구사항을 문서화했습니다.
포맷 복구 워크플로 .github/workflows/ci-format-causal-repair.yml	특정 pull request의 head와 변경 범위를 검증합니다. cargo fmt, 계약 테스트, workspace 테스트와 clippy를 실행합니다. 포맷 수정 후 워크플로 파일을 삭제하고 수정 commit을 pull request head에 push합니다.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 271ab

The formatting-repair workflow can consume runners for a Draft PR and currently uses a runner label rejected by workflow linting. Update the Draft condition and runner label before merge so the repair path can run as intended without defeating the Draft-runner policy.

Resolved at exact head eda2decf22cf2bead5c56ea7d9bf1e59638bcdf3. The CC BY 4.0 arXiv PDF is now committed at docs/papers/ci-at-scale-lean-green-fast-arxiv-2501.03440.pdf; local validation reports a three-page PDF with SHA-256 d84b6b286cc98f98e2c24a9ccbbb9394a61ec284456db8eba587df48c6c332c5.

Exact-head repair update: CI 33940872541 on predecessor eda2decf22cf2bead5c56ea7d9bf1e59638bcdf3 acquired a real ubuntu-24.04 runner and failed only at cargo fmt --check; rustfmt required a one-line assertion form in tests/workflow_queue_contract.rs. Commit 13fc6a1b9b3f5af0b7c6acfb79de6c46fd72de3a applies exactly that formatting delta and changes no queue/concurrency behavior. GitHub still reports the PR Ready/mergeable on protected main@5829a0f08d78de464dd24393ce5d0f25fba9d126. Fresh exact-head runs are CI 33954367435, Fuzz 33954367424, CodeQL 33954367497, SAST 33954367509, Security 33954367550; all are currently queued and therefore non-passing. Predecessor Fuzz GREEN and CI failure do not transfer. Keep Ready so the exact source can execute; no no-op churn or bypass.

[seonghobae]

Fresh workflow-integrity finding to fold into this existing same-path CI/Fuzz writer rather than open a competing workflow PR.

Exact evidence: protected main@a52ccd0a24a727d9349bb32def7713882d8cad1e and current #166 e892be0875c14967a208fe89570740473839aa0e both leave the CI actions/checkout step without an explicit PR source ref or post-checkout SHA assertion. On #175, nominal exact-head CI run 34035086747 / job 101491566666 succeeded but its logs prove checkout fetched refs/pull/175/merge and executed merge commit 0200dae8ae81436567e2512904ffed872cd038fe, not source head 45f2aecd40983b785c1e37489596af641dedcc84. The focused verifier exists precisely because ordinary CI therefore does not prove the source SHA directly.

Acceptance for #166 when it next executes on a non-disposable coherent base: for every repository checkout in CI and Fuzz, bind ref to ${{ github.event.pull_request.head.sha || github.sha }} and immediately assert git rev-parse HEAD equals that same expression; keep current PR/push behavior, immutable action pins, Draft queue-pressure semantics and synchronization-only cancellation intact. Add a repository regression that fails if the exact-source binding/assertion disappears. Do not remove candidate-base compatibility checks elsewhere: source-head proof and merge-candidate compatibility are distinct evidence. No no-op source churn is needed while the existing #166 exact head is queued.

Fresh downstream evidence confirms this exact-source-checkout repair is still a live prerequisite, not documentation polish. On current protected main@a52ccd0a24a727d9349bb32def7713882d8cad1e, #196 source 78149209ed2c3c7443edacad423e26c4ae6c521d CI 34221566705 / job 102045647544 fetched +757e44254017cc1e86e661ae93e7cde0204537e6:refs/remotes/pull/196/merge and logged HEAD is now at 757e442 Merge 78149209... into eeddc491.... #198 RED candidate likewise checked out a synthetic merge ref before format. Therefore current protected workflow successes cannot be labeled exact source-head receipts under Wardnet's completion contract.

#166 already contains the minimum causal repair: explicit ref: ${{ github.event.pull_request.head.sha || github.sha }} plus post-checkout SHA equality for CI/Fuzz. Preserve this scope and current exact head; once central CodeQL/governance admission permits ordinary protected merge, downstream state/security PRs must reacquire exact-source format/test/Clippy/fuzz evidence rather than promote synthetic-merge predecessors.
