I rewrote a private Bitbucket Cloud repository’s history to remove 19 large historical image blobs—about 228 MB—and force-pushed the cleaned main branch. A fresh mirror of the reachable history is about 243 MB, but Bitbucket still reports roughly 665 MB and the workspace is over 800 MB.
There are no pull requests, tags, or pipelines. Could Atlassian staff trigger server-side garbage collection and remove any hidden references? Please contact me privately for the workspace and repository identifiers.
