- Use a dedicated migration marker (_blobstore/.migrated) instead of the heuristic blob-count sentinel in upgradeToGlobalBlobstore; this correctly skips the upgrade scan on fresh installs where the blobstore is empty and has never had blobs. - Remove the stale gc.CleanRepo ShouldNotBeNil assertion in local_test.go that had no state change between calls and was incorrect once CleanRepo became idempotent for missing blobs. - Accept HTTP 409 Conflict (bucket already exists) as a success case in the three S3 bucket-creation panics in controller_test.go, preventing test flakiness when the S3 mock retains bucket state across Convey blocks.
