Implemented

  • Bounded, checksum-pinned Gitleaks 8.30.1 in cicd-suite (composite and reusable).
  • HTTPS-only downloads and redirects, explicit deadlines, redacted output, live positive/negative controls using the effective configuration.
  • Tree + complete-history scanning by default. Optional introduced-commit PR mode retains committed-then-deleted detection; non-PR runs remain full.
  • Direct SHA-pinned caller preserving scan / gitleaks; suite scripts and baseline are selected by that same pin.
  • Read-only CI evidence collector and 360-repository standard-path inventory.

Real runner evidence

  • Initial real-detector fixture job: 19 seconds, success (41138675983).
  • Actual full-history caller canary: 10 seconds, success (41138737134).
  • Hardened current-head caller canary: 7 seconds, success (41138971199).
  • SonarCloud now passes after enforcing HTTPS-only redirects; GitGuardian, component audit and shell-contract controls pass on current head. Other analyses may still be pending.

Rollout boundary

Only cicd-suite's caller is changed, on this unmerged branch. Inventory: 338 standard reusable-call review candidates, 14 custom scanners, 8 without the standard-path caller. No consumer has been silently rewritten.

The retained legacy scanner still fails before startup; this PR does not pretend it has passed. Specialised Rust/shell coverage must be preserved or proven redundant before wholesale replacement of the old bundle. Keep this PR draft until coverage comparison and remaining checks are resolved. No admin merge, context deletion, fake green or token-scope broadening.

See docs/SECRET-SCANNER-ROLLOUT.adoc, docs/SECRET-SCAN-PERFORMANCE.adoc and docs/secret-scanner-rollout-inventory.json for evidence, scope, migration gates and handoff requirements.

Review comments at @actions/secret-scan-check/check.sh:
- Around line 44-46: Update the config selection in check.sh so pull_request
scans use trusted configuration rather than files supplied by the PR, and ensure
.gitleaksignore is also trusted or the check fails if the PR changes it. Pass
the trusted config through to control.sh while preserving the existing scan
flow.

Review comments at @README.adoc:
- Around line 399-400: Update the exit-status description for
scripts/inspect-pr-ci.sh to say that exit 2 means collection did not complete,
including when arguments are invalid or gh or jq is missing; identify denied API
probes as one incomplete-inspection case. Preserve the existing distinction that
exit 0 means collection succeeded, not that CI passed.

Review comments at @scripts/inspect-pr-ci.sh:
- Line 38: Update `collect` so a confirmed 404 from the required-status-checks
endpoint is recorded as an absent classic configuration, not `probe_error`; keep
denied and other failed probes distinct so they still trigger the existing
failure path. Add a test verifying that an absent classic configuration allows
inspection to succeed.

34-45: Functional Correctness

The requested inspection is incomplete because the available result only searched for references in selected tests and documentation. It does not establish the scan commands, baseline contents, or whether a non-extending .gitleaks.toml can scan .gitleaks-estate.toml.

.github/workflows/secret-scanner.yml: 1

19-23: Functional Correctness

The concern is refuted. The pinned tree matches the checked-out tree for the three paths named in the comment.

The reusable workflow checks out the scanner implementation from the uses: SHA. The caller pins 50dc27f47e39f7ac046596c071ed4ea80b4989e0, and the reusable workflow derives that SHA and checks it out into suite. The diff of actions/secret-scan-check, config/gitleaks and .github/workflows/secret-scanner-reusable.yml between 50dc27f and the sandbox HEAD produced no output. The commit exists. The command exited 0, so the diff ran successfully.

P2 Badge Flatten paginated branch rules before reporting them

For every successful rules query, paginated wraps each API page in an outer array, so a one-page response such as [rule1, rule2] is reported as rules: [[rule1, rule2]]; multiple pages add further sibling arrays. The gh api --paginate documentation confirms that each page is emitted as a separate JSON array or object, and jq -s therefore preserves page boundaries. Normalize this endpoint's pages into one rule array, otherwise downstream consumers cannot iterate .rules[] as rule objects despite the report claiming to expose effective branch rules.

P2 Badge Include startup failures in zero-job detection

When GitHub concludes a zero-job run as startup_failure, the jobs are fetched because the run is non-successful, but this equality check excludes it from zero_job_failures. startup_failure is an explicitly supported run result in the gh run list status set, and it is precisely the non-execution condition this collector is intended to surface, so accept it alongside failure when the completed run has no jobs.

P2 Badge Trigger the owner guard for secret-scanner workflow edits

Adding secret-scanner-reusable to this guard does not actually protect later edits to that workflow: the language-gates-self-test.yml push and PR path filters omit .github/workflows/secret-scanner-reusable.yml, while secret-scanner-self-test.yml never invokes tests/gate-action-owners.sh. Consequently, a PR that only adds an unpinned or policy-disallowed uses: reference to the scanner reusable will not run the owner guard at all; add the workflow to both path-filter lists or invoke the guard from the scanner self-test.
