 # ADR-015: Backup/Restore Streaming Architecture
 
+> **Status update (ADR-102, 2026):** the client-controlled streaming model decided
+> here is live. **Phase 1 (backup download)** ships as
+> `api/app/lib/backup_streaming.py` + `backup_archive.py`. **Phase 2 (restore upload)**,
+> tracked below as "🚧 IN PROGRESS", was *delivered* by
+> [ADR-102](ADR-102-portable-backup-and-restore-with-clone-merge-semantics.md) — the
+> portable `kg-backup/2` format with clone/merge/restamp restore semantics, epoch
+> reconciliation, and the async `restore_worker`. ADR-102 builds **on** this ADR's
+> streaming foundation rather than replacing it, so ADR-015 remains Accepted; the
+> Phase-2 progress markers below are historical (read them as "done, see ADR-102").

 ## Overview
 
 Think about how you back up photos from your phone. The photos live on your device, not on some cloud server. You initiate the backup, your phone sends the files where you want them, and you can restore them whenever needed. Now imagine if instead, all your photos were "backed up" to a folder on Apple's servers that you couldn't even access - that would be pretty useless, right?
