 - [Phase ?]: Delta-only matching (no backfill/suppression table) structurally prevents backfill-flood for new saved-search profiles (12-01, D-07)
 - [Phase ?]: TenderMailService swallows missing-SmtpConfig and send-failure into a single boolean (never throws) so the digest cron gets one clean success signal for stamping notifiedAt
 - [Phase ?]: TenderDigestScheduler.runDigest(now) takes an injectable clock parameter for testable Monday-only weekly-digest gating
+- [Phase ?]: Instant-Dispatch filtert die bereits geladenen savedSearches (kein zweiter Query); notifiedAt/channel='instant' nur nach Erfolg gestempelt — identisches Gate wie Digest (D-06)
