…ter local-log loss A leader that comes up below the seal with an empty local log (a full local-storage wipe / disaster recovery where the controller, whose metadata survived, elects a replica that came back empty) has no peer to replicate the classic prefix from -- that prefix lives only in the remote tier. The ConsolidationReconciler now starts consolidation for such a leader (when remote storage is enabled) instead of retrying forever, so the fetcher lands below the diskless WAL start, hits OFFSET_MOVED_TO_TIERED_STORAGE, and rebuilds the leader-epoch cache and producer snapshot from remote.
