+- **Webhook and import success now means the source data is durable.** moodLog
+  writes before acknowledging delivery, while Withings ECG callbacks enter a
+  durable queue with bounded retry and replay-safe processing. WHOOP backfills
+  commit bounded chunks without advancing failed resource cursors, and legacy

+  processes stable measurement IDs in bounded batches, and preserves recovery

 - **Device and mood edits no longer lose related state.** Same-user APNs
   registrations merge transactionally without crossing account boundaries,
   refresh-token bindings follow the surviving device, and mood edits preserve
