sec(ci): pin actions/* refs to commit SHAs (backend#1491, D10) - #461
Merged
Conversation
Pin every actions/* ref to the full 40-char commit SHA it currently resolves to, with a trailing exact-version comment (D10, RFC-BACKEND-1405). Behaviour-preserving: no version changes, only removal of silent tag mutation. tracebloc/* refs stay on @main by design; third-party refs were pinned under backend#1490. Part of tracebloc/backend#1491. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

FR on staging → Ready for prod (staging FR sweep, 2026-08-06). Basis: CI/tooling-only change with no product runtime surface — verified green through code review + Bugbot on develop and the fr-gated staging promotion. No product-behavior verification required for this class. |

Note
Low Risk
Mechanical, behavior-preserving CI ref pinning with no runtime or application code changes; workflow logic and action versions are unchanged.
Overview
CI supply-chain hardening (D10): Every
actions/*step that used floating tags (@v7,@v11, etc.) now references the same release via a 40-character commit SHA, with a trailing# vX.Y.Zcomment—matching the repo’s third-party pinning policy. No action versions change; only tag mutation risk is removed.Scope: 41 call sites across 13 workflow files—
checkout,setup-go,setup-python,upload-artifact,download-artifact,add-to-project, andstale. Third-party actions (e.g.azure/setup-helm,sigstore/cosign-installer) were already SHA-pinned and are untouched;tracebloc/*refs stay on@mainby design.Reviewed by Cursor Bugbot for commit 39fdeda.
