 ### vendored-mirror-unpinned-actions
 - description: Unpinned `uses:` refs inside `9-archive/rhodium-standard-repositories/**` -- the vendored mirror of the RSR canon (gitlab.com/hyperpolymath/rhodium-standard-repositories). These are OTHER repositories' workflows reproduced here as templates, and this repo's own CI lock gate (.github/workflows/actions-lock-gate.yml -> .githooks/validate-actions-lock.sh) covers only the root .github tree, so `.githooks/validate-sha-pins.sh` matches that scope and skips the mirror rather than silently passing it. Re-pinning the mirror here fixes no live runner and desynchronises the copy; it is fixed upstream, or the mirror retires. MEASURED 2026-09-21 by the probe.
