+## [0.1.9] - 2026.08.28
+### Added
+- `runDailyAlertSearch` selects today's unused delegated JWT from the stored batch timezone, runs `runAlertSearchCycle`, and consumes that JWT only when both Endorser and Partner complete (`success` or `empty`)
+
+
 ## [0.1.8] - 2026.08.27
 ### Added
 - `runAlertSearchCycle` integration of cursor load, alertSearch retrieve, and independent cursor advance

 The **delegated** JWT is sent as `Authorization: Bearer`. Pass independent `endorserAfterId` / `partnerAfterDate` (or omit them on first run). Nearby search uses the alertSearch bbox (`minLocLat`, `maxLocLat`, `minLocLon`, `maxLocLon`).
 
-`loadAlertSearchCursors` / `retrieveAlertSearch` / `advanceAlertSearchCursors` (or `runAlertSearchCycle`) persist those bounds per user DID in SQLite. Cursors advance only after a complete `success` retrieval (not `empty`, `pagination`, or errors). A Partner page of 50 rows that share the oldest `updatedAt` is `pagination` because exclusive `beforeDate` cannot drain timestamp ties. They are not wired to the scheduler yet.

+
+`runDailyAlertSearch(userId, now?)` is a callable daily orchestrator (not a cron job). It uses the latest batch's stored IANA timezone to pick today's unused delegated JWT, runs `runAlertSearchCycle` with that JWT, and marks that specific JWT consumed only when both Endorser and Partner complete (`success` or `empty`, including both empty). Pagination or source failures leave the JWT unused so the same day can be retried. An invalid stored timezone is an error; there is no fallback to the server timezone. This is not wired to the existing FCM scheduler.
