ci: stop draft PR jobs from occupying runners

[seonghobae]

Summary

• keep Wardnet-owned CI and path-filtered Fuzz from consuming a local runner when the triggering PR state is Draft;
• cancel only a genuinely superseded PR head: synchronize is the sole cancel-in-progress event;
• keep state-only reopened / ready_for_review validation in run-specific groups so an unchanged head cannot be discarded;
• use immutable, distinct wardnet-ci / wardnet-fuzz concurrency prefixes plus repository identity instead of mutable workflow display names;
• do not use converted_to_draft or closed as cancellation triggers;
• preserve the existing Rust/fuzz validation surface and central required-workflow ownership;
• document the bounded queue-coalescing rationale with ICSE 2025 research and redistribution licensing.

TDD / review repair lineage

The original candidate incorrectly treated Draft/closed transitions as supersession and used mutable github.workflow in the concurrency key. Fresh review also showed that Fuzz's paths filter made the proposed state-transition cancellation unreliable.

• RED fbbccaadded691d7ce048f1ed9fe50307ab4e386 requires fixed per-workflow prefixes, cancellation only on synchronize, no Draft/closed cancellation triggers, the Draft job guard, and retention of the Fuzz path filter.
• CI causal implementation fa7c95eccc6b1319109dcd2372040b67bbac6a3c applies that contract.
• Fuzz causal implementation 81b9048d75332367d13cdb9dd939f751599e48b0 applies the same contract without removing path-filtered validation.
• 95360a0261d9e5f5718fc434a13237d0abda260f records the state/head-supersession distinction and cites Juloori et al. (ICSE 2025 / arXiv:2501.03440) with CC BY 4.0 redistribution status.
• eda2decf22cf2bead5c56ea7d9bf1e59638bcdf3 adds the redistribution-permitted paper artifact.
• CI 33940872541 then acquired ubuntu-24.04 and failed deterministically only at cargo fmt --check in tests/workflow_queue_contract.rs.
• causal formatting repair 13fc6a1b9b3f5af0b7c6acfb79de6c46fd72de3a applies exactly rustfmt's required test formatting without changing workflow semantics.

All currently returned inline review threads were resolved before the latest base adoption. Resolution verifies findings; it is not independent approval, and current-head review/thread evidence must remain valid.

Protected-main adoption — 2026-09-06 KST

Protected/default main advanced through #171 to exact a52ccd0a24a727d9349bb32def7713882d8cad1e. Fresh comparison proved the entire protected-only delta since this branch's prior base 5829a0f08d78de464dd24393ce5d0f25fba9d126 is the two #171 ADR/index files and does not overlap this PR's five-path queue-repair delta.

The branch therefore adopted current protected truth non-destructively with two-parent merge e892be0875c14967a208fe89570740473839aa0e, preserving prior exact queue candidate 13fc6a1b9b3f5af0b7c6acfb79de6c46fd72de3a and exact protected main@a52ccd0... as parents. The protected ADR blobs were adopted byte-for-byte. No force push or destructive rebase was used.

Fresh compare against protected main is merge-base=a52ccd0..., ahead 11 / behind 0. The effective feature delta remains exactly five paths: .github/workflows/ci.yml, .github/workflows/fuzz.yml, tests/workflow_queue_contract.rs, docs/doctoring/ci-queue-concurrency.md, and the retained ICSE/arXiv paper artifact.

Exact-current execution

All workflow conclusions from 13fc6a1... and earlier are predecessor evidence after the real ancestry movement. Current exact head is e892be0875c14967a208fe89570740473839aa0e.

Fresh current-head workflows are non-passing/queued: CI 34019919504, Fuzz 34019919226, Security Scan 34019919220, SAST Semgrep 34019919217, and CodeQL PR 34019919259. CI rust job 101450478277 is queued pre-checkout on explicit ubuntu-24.04 with steps=[] and no runner id/name/group. This exact specimen is delegated to .github#712; do not create no-op redispatch commits or change runner selectors.

Owner boundary

This is a bounded repository-owned queue-pressure repair. Organization ruleset 18156473 owns Security Scan, SAST Semgrep, CodeQL, OpenCode, Strix, Noema, and merge-scheduler workflows through ContextualWisdomLab/.github. Residual runner/materialization defects remain central .github#712 work; Wardnet does not copy or weaken those workflows.

The live ruleset still carries the solo-maintainer approval/bypass defect tracked by .github#772. Self-approval and model/bot-as-human approval are forbidden; routine OrganizationAdmin bypass is not product-merge authorization. GitHub may display this PR Ready, but exact-current gates are non-passing and no merge call is used as a governance probe.

Single-writer and merge boundary

PR #130 remains the sole writer for docs/product-technical-gap-baseline.md; current evidence is handed to that lane without editing the ledger here.

Merge only after one unchanged exact current head has zero valid unresolved review findings/threads, fresh protected-base compatibility, and all then-required deterministic/security/SAST/coverage/package/SBOM/provenance/governance gates terminal-valid through an ordinary path satisfiable without fabricated approval. The guarded chicken-and-egg bypass does not apply to ordinary queued runner evidence. No force push/destructive rebase, gate weakening, self/model approval, routine bypass or predecessor-evidence reuse.

Walkthrough

CI 및 fuzz 워크플로의 pull request 이벤트와 동시성 그룹을 조정했습니다. synchronize에서만 이전 실행을 취소합니다. draft pull request의 작업 실행을 제한합니다. 계약 테스트와 정책 문서를 갱신했습니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to e892b

This changes PR workflow triggering, cancellation, and draft-job execution to reduce runner use while preserving validation behavior. The current head still lacks successful terminal CI and security validation, so it should not merge until those required checks pass.

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.

[seonghobae]

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.
