Step 2: Rebuild completion status port - New runtime.RebuildCompletionStatus + DeriveRebuildCommitted: reusable shaping logic for post-rebuild snapshot → RebuildCommitted event - block_recovery.go OnRebuildCompleted: delegates to DeriveRebuildCommitted, host only reads raw snapshot via readRebuildStatus (thin binding) - Removed 15 lines of inline flushedLSN/checkpointLSN/achievedLSN computation Step 3: Recovery bundle factory - New buildRecoveryBundle: shared host-side setup for both catch-up and rebuild (creates Reader + Pinner + StorageAdapter + Executor + RecoveryDriver) - runCatchUp and runRebuild both use buildRecoveryBundle instead of duplicating the WithVolume → NewReader → NewPinner → NewStorageAdapter → NewExecutor → RecoveryDriver chain - runCatchUp/runRebuild are now thin host-shell methods Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
