cannot modify status of DONE build %s

Error message

cannot modify status of DONE build %s

What it means

HCP registry guard from Bucket.UpdateBuildStatus: the target build is already DONE and HCP does not allow modifying a completed build's status, so the update is rejected to avoid corrupting the finished build.

Solutions

1. Skip status updates for builds already marked DONE
2. Create a new version/fingerprint for further changes instead of mutating the completed build
