fix(ci): SHA-pinned Security Scan callee + re-key CodeQL lock entry - #399
Merged
Merged
Conversation
echidna sets sha_pinning_required, so the panic-attack reusable it called at 27b3d93 was refused at startup: that callee's steps were tag refs. The callee now pins its steps by SHA (hyperpolymath/panic-attack#209, merged as 5ee2565).

codeql.yml uses github/codeql-action@v4.38.1, but its actions.lock entry still pinned v4.38.0, so every CodeQL run died at startup. Re-keyed by hand to the dereferenced tag commit 1c5b6756 (gh actions-lock write mode de-pins). --no-fix findings for codeql.yml: 3 -> 0; all other findings unchanged.

Priority: ➖ Normal Estimated code review effort: 1 (Trivial) | ~5 minutes Change: Bug fix Merge Risk: 🔵 Low · up to This change restores the Security Scan workflow by pointing it at a reusable workflow version that meets SHA pinning requirements. It can be merged. The owner should know that the scanner itself still installs from a moving branch. The owner should also know that, once the dispatch token is configured, that token is exposed to the same runner as the scanner. Both should be addressed upstream in panic-attack. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The workflow remains SHA-pinned and its normal repository-token permission remains read-only. However, the scanner executes code selected from a mutable upstream branch and shares a job with token-bearing dispatch. Restoring execution could activate these existing risks. Actual dispatch-token availability, authority, and before-and-after runtime behavior remain unconfirmed. Retained concerns

Review comments at @.github/workflows/security-scan.yml:
- Line 27: Update the reusable workflow reference for panic-attack so the Cargo
installation uses a reviewed, immutable commit rather than the moving main
branch; keep the scanner source pin aligned with the workflow’s pinned revision.
- Line 27: Update the reusable scan workflow so “Send to verisimdb-data” runs in
a separate job on a clean runner from “Run scan,” transferring only the scan
result between jobs and keeping VERISIMDB_PAT confined to the dispatch job.

Why
Security Scan. echidna sets
sha_pinning_required: true. The panic-attack reusable it called, at27b3d93, had tag-ref steps, so every Security Scan run ended instartup_failure.hyperpolymath/panic-attack#209 SHA-pins those steps. It merged as
5ee2565, a signed and verified commit. This PR moves the callee pin to that commit.VERISIMDB_PATis stillrequired: falsein the callee. Without the secret, the callee skips the cross-repo dispatch and emits a::notice::, so the scan itself can pass.CodeQL (second commit).
codeql.ymlusesgithub/codeql-action@v4.38.1, butactions.lockstill pinnedv4.38.0. So CodeQL has ended instartup_failureonmain(the 2026-10-01 scheduled run) and on every PR.I re-keyed the entry by hand to the dereferenced tag commit
1c5b6756.gh actions-lockwrite mode de-pins SHAs, so I did not use it. The same fix restored panic-attack's CodeQL: its run on5ee2565concludedsuccess.Verification
gh actions-lock --no-fix --json:Not fixed here (owner action)

Pre-existing reds (deferred)
These fail identically on
main(ba373a8). Each failing check context is deferred to #401:Dependency audit(#401),governance / Workflow security linter(#401),governance / Validate Hypatia Baseline(#401, #314),lint-workflows(#401). On this head, CodeQL goes fromstartup_failuretosuccess, and the requiredscan / gitleaks,scan / rust-secretsandscan / shell-secretsall pass. Security Scan runs only on push and schedule, so the callee pin is proved by its firstmainrun after merge.
