release-train: develop -> staging - #462

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>

Automated promotion by the release train (RFC-0008 D14). Head is the train-managed
release-train/to-stagingbranch (a mirror ofdevelop), so it never collides with a human PR. Merged only when the fr-gate is green.Note
Low Risk
CI-only reference changes with no application or release logic changes; behavior should match the same action versions already in use.
Overview
Pins third-party GitHub Actions across CI workflows from mutable version tags (e.g.
@v7) to immutable commit SHAs, with the original version kept in an inline comment for readability.Affected actions include
actions/checkout,actions/setup-go,actions/setup-python,actions/upload-artifact,actions/download-artifact,actions/add-to-project, andactions/stale, touching build, release, e2e, drift checks, vulncheck, mutation, kanban, and stale-backlog workflows. Workflow triggers, job logic, and secrets usage are unchanged—only theuses:references are hardened against tag-moving supply-chain risk.Reviewed by Cursor Bugbot for commit 6830dd0.
