Phase 7: Plugin-Gate, Event-Envelope, Pro-Handler Outbox-Verarbeitung
7.1 Plugin-Gate korrigiert: - require_active_plugin nutzt current_user fuer tenant_id statt current_setting() - Keine neue DB-Session mehr — nutzt bestehende get_db Dependency - Fail-closed bei Fehlern 7.4 Einheitlicher Event-Envelope: - Sauberes Envelope mit event_id, event_name, tenant_id, aggregate_type, aggregate_id, occurred_at, correlation_id, schema_version, data - Keine _-Praefixe mehr im payload - Handler empfangen envelope statt rohes payload 7.6 Verarbeitung pro Handler: - Globaler consumer_inbox Check entfernt - Pro-Handler Idempotency: outbox_deliveries pruefen ob Handler bereits erfolgreich - Bereits erfolgreiche Handler werden uebersprungen - consumer_inbox pro Handler geschrieben 7.7 no_handlers: Bereits implementiert (terminaler Status) 7.8 Cron-Jobs: Bereits mit Redis SET NX Locking implementiert Tests: 23/23 Outbox-Tests bestanden
