Build run verification unavailable

typehttps://docs.frem.sh/reference/api/errors/build-run-verification-unavailable
HTTP status503 Service Unavailable

What it means

You sent build_run_id, and this deployment cannot reach the Actions database to verify it.

The attestation was not signed. fremforge refuses to sign a run reference it cannot verify, because an unverified run reference looks like build provenance while being only the caller’s word.

What to do

Retry, or omit build_run_id to get an attestation without a verified build-run reference.

Response shape

All fremforge API errors are RFC 9457 problem+json:

{
  "type": "https://docs.frem.sh/reference/api/errors/build-run-verification-unavailable",
  "title": "Service Unavailable",
  "status": 503,
  "detail": "..."
}

Branch on type, not on title or detail - those are human-readable and may be reworded.
