Harden the protected runner-assignment diagnostic at three current evidence boundaries:
prevent the active read-only GitHub credential from escaping through gh subprocess start/nonzero diagnostics;
prevent GitHub's queued-job started_at timestamp from being misclassified as proof that a runner was assigned when runner_id is 0 and runner_name is empty; and
preserve the stable bounded malformed-JSON evidence contract even when JSON.parse itself throws after duplicate-key screening.
bdb486468daaa524f683a033823a96b72de762f0 implements exact-string redaction before diagnostic normalization/bounding.
fb04907e3f64ad9d2741e222ff85fe354ca94b78 reproduces queued started_at with no runner identity.
9f2557d2a7f0cfa317c324b986c69d45d3d13f52 makes positive runner identity—not queue timestamps—the assignment authority.
Existing parser-coverage tests already require GitHub Actions evidence read returned malformed JSON. when JSON parsing fails after raw-byte/fatal-UTF-8/duplicate-key validation. 5f861fbaa0f21fc690620846a0c287b2f6c2c63b fixes the implementation to preserve that fail-closed diagnostic instead of leaking a raw parser exception.
After fix(security): harden maintainer readiness token capability reads #395 integrated, b0a7a38b9f1bd849adfa2bf72d90b6a3893de6a2 non-destructively restacks the exact branch on protected maina634066feb6ace12da2f305fe0e2691a15240997. Fresh comparison is ahead-only, zero behind, and contains only the intended runner-assignment source/tests/doctoring delta.

Current exact head: b0a7a38b9f1bd849adfa2bf72d90b6a3893de6a2 on protected base a634066feb6ace12da2f305fe0e2691a15240997.
Fresh exact-head runs are reviewer-ci 31950820931, application CI 31950821039, and central Security Scan 31950820917. They are currently pending/queued and therefore non-passing. The current PR has no unresolved review threads. No predecessor-head or pre-restack evidence is promoted to this head.
Authority boundary
This changes only Noema's runner-assignment evidence interpretation and credential-safe diagnostics. It does not alter GitHub permissions, workflow/check authority, merge/release/deployment authority, credential-source governance, hosted-runner allocation, or any central repository. A runner_assignment_stalled result remains diagnostic evidence rather than a substitute for the actual required CI/security/review result.
It does not resolve the broader KV-vs-ephemeral-token policy decision in #111 or claim that Noema can repair GitHub-hosted runner capacity.

기본 실행은 NOEMA_MAINTAINER_TOKEN_PATH에서 위임 토큰을 읽습니다. gh subprocess에는 최소 환경과 토큰을 전달합니다. capability 파일이 없으면 ambient GH_TOKEN을 사용하지 않고 실패합니다.

redactExactSecret이 오류 메시지와 stderr의 정확한 토큰 값을 [REDACTED]로 치환합니다. stderr가 없는 실패는 제한된 오류 메시지를 생성합니다.
started_at만 있는 queued 작업은 미할당으로 유지합니다. 양의 runner_id 또는 비어 있지 않은 runner_name만 할당 증거로 인정합니다.

The PR hardens runner-assignment diagnostics by redacting credentials, requiring positive runner identity, and preserving bounded malformed-JSON errors. It is mergeable with explicit owner awareness that the integration tests do not verify the delegated credential is forwarded to the GitHub CLI or preferred over an ambient credential, leaving a bounded risk of using the wrong credential during diagnostics.

Stale comment
Review of c4a0ffb vs maina634066 (9 files, +312/−27).
CodeRabbit on this exact head is rate-limited. GitHub status: “Review rate limited” / “Review limit reached” — 1 included review per rolling hour. The last completed CodeRabbit pass covered c866654, not this SHA. After the hourly window resets, comment @coderabbitai review on this PR so the current head gets a completed pass. Do not treat the rate-limit status as scanner success.
Prior CodeRabbit finding is addressed on this head. Both gh shims now fail unless GH_TOKEN equals the capability-file token, and both integration tests set a distinct ambient decoy (f387edf–c4a0ffb). The thread is resolved. That gap is closed.
The three hardenings match the stated contract.
Production main() without an injected gh_api reads NOEMA_MAINTAINER_TOKEN_PATH via readDelegatedGithubToken and does not use ambient GH_TOKEN.
ghApi exact-redacts the active token from spawn error.message and stderr before bounding the diagnostic.
assignmentObserved requires a positive runner_id or non-empty runner_name. A queued job with started_at set, runner_id: 0, and empty runner_name stays unassigned / runner_assignment_stalled.
Local verification on Node 24.19.0 / npm 11.17.0: the six runner-assignment test files — 38 tests, all passed.
Do this before merge
Add the missing CHANGELOG.md Unreleased bullet for the three behavior changes (inline note on the docs contract test). Doctoring already records them; Unreleased does not. Repo convention is that every behavior change updates Unreleased.
Wait for required checks (verify, Security Scan trivy-fs / osv-scan / dependency-review) to reach terminal success on this exact head. They are still pending/queued on c4a0ffb. Queued is not passing.
Re-run CodeRabbit on this SHA after the hourly limit resets.
Keep this diagnostic in its authority box: a runner_assignment_* result does not satisfy required checks, review, merge, release, or deployment, and it does not close #30 or #111.
No independently confirmed runtime or credential-leak defect at this head. Not approving until the changelog bullet lands and required checks are green on c4a0ffb.

Doctoring and this contract test now record capability-file ingress and started_at losing assignment authority. CHANGELOG.md Unreleased still only describes the original audit addition.
Before merge, add an Unreleased bullet that names all three operator-visible behavior changes:
production operations:runner-assignment reads NOEMA_MAINTAINER_TOKEN_PATH and fails closed when only ambient GH_TOKEN is present;
gh spawn/stderr diagnostics exact-redact the active token as [REDACTED];
assignment authority is a positive runner_id or non-empty runner_name — a queued started_at is not assignment evidence.

Review at f4a4bc9
The runtime hardening is sound. Production operations:runner-assignment reads NOEMA_MAINTAINER_TOKEN_PATH, fails closed when only ambient GH_TOKEN is present, exact-redacts the active token as [REDACTED] on gh spawn/stderr, and treats assignment as a positive runner_id or non-empty runner_name. Queued started_at is not assignment evidence. The earlier CodeRabbit gh-shim finding is addressed on this head.
Do not merge this head. CHANGELOG.md Unreleased still describes only the original audit addition, so an operator reading the changelog cannot see the three production behavior changes or the next action (prepare the capability file; do not treat PASS as required Check, formal review, or merge authority). Doctoring and this contract test already record those rules; Unreleased does not.
Landing vehicle: #401 (64c6213) adds the Unreleased bullet and locks the phrases in test/actions-runner-assignment-docs.test.ts. Prefer #401, or fast-forward this branch to that commit, then wait for exact-head CI / Security Scan / reviewer to terminate successfully. Queued checks and runner_assignment_stalled are not merge authority. This does not close #30.

Changes requested at f4a4bc9
Runtime hardening is sound: capability-file ingress, exact [REDACTED] token redaction, and started_at is not assignment evidence. No confirmed credential leak or ambient-token fallback remains on the production CLI path. The earlier CodeRabbit gh-shim finding is addressed.
The merge blocker is Unreleased. CHANGELOG.md still describes only the original audit addition, so operators cannot see the three production behavior changes or the next action (prepare NOEMA_MAINTAINER_TOKEN_PATH; do not treat PASS as required Check, formal review, or merge authority).
Land #401 (64c6213), or fast-forward this branch to that commit. Then wait for exact-head CI, Security Scan, and reviewer to terminate successfully. Queued checks are not merge authority. This does not close #30.
