 - [Phase ?]: TenderTriage (neu, per-user, kein forTenant/RLS) + favOnly-Sentinel-ID '__none__' für garantierten Zero-Match statt versehentlich ungefilterter Liste
 - [Phase ?]: TenderSavedSearch hat keinen Tender-FK — speichert nur Filterkriterien, unkritisch bei Retention.
 - [Phase ?]: page/tender-URL-Params bewusst aus dem Suchprofil-Payload ausgeschlossen (Navigations-/View-State, kein Filter-State).
+- [Phase ?]: Single notifiedAt field (not two per-channel timestamps) as the matched-vs-notified eligibility gate (12-01, D-06)
+- [Phase ?]: Delta-only matching (no backfill/suppression table) structurally prevents backfill-flood for new saved-search profiles (12-01, D-07)
