Incremental sync (v2)
The companion now uploads only changed loot entries instead of the full history on every sync:
- Delta upload — only entries whose content changed are sent.
- Manifest reconciliation — a daily/at-startup safety net that self-heals any drift with the server.
- Persisted sync state — restarting the app no longer re-uploads the whole history.
Requires the matching backend (live) and the v2 addon (1.2.0+) for delta syncing; older addons keep working via the v1 path. Auto-update will bring existing installs to this version.
