- Updated package dependencies to include `@sentry/node` for error tracking.
- Refactored command routing to incorporate user and guild blacklisting checks, improving command execution safety.
- Enhanced health server metrics to include queue waiting times, providing better insights into system performance.

+## Post-Phase – Harden (Sharding / Gates / Observability) (Status: implementiert)
+
+### Abgeschlossen (Code)
+
+- Confirmations (Moderation + Guildbackup) in Redis mit TTL statt Prozess-`Map`
+- Command-Registrierung einmal im Manager (Redis-Lock); Recurring Jobs einmal (Primary-Shard + Lock)
+- Modul-Toggles + FeatureFlags + User-/Guild-Blacklists im Bot erzwungen (`routeCommand`, Events, GuildCreate leave)
+- Moderation: Hierarchy-Checks, Duration vor Ban-Confirm, Timeout-Cap 28d, warn remove guild-scoped, atomare Case-Nummern, Temp-Ban Job-Dedup + UNBAN-Case, `setDefaultMemberPermissions`
+- Sentry (`@sentry/node`) in Bot + WebUI (`instrumentation.ts`); echte Prometheus-Metrics (`/metrics`)
+- Interaction-Registry statt if-Kette; Unit-Tests für Duration, Confirm-Store, Module-Gates, Metrics
+
+### Manuell testen
+
+- [ ] Ban mit Dauer: Confirm auf anderem Shard / nach Restart innerhalb TTL
+- [ ] Dashboard: Modul Moderation aus → `/ban` antwortet „Modul deaktiviert“
+- [ ] Owner: User-Blacklist → Interactions blockiert; Guild-Blacklist → Bot verlässt Server
+- [ ] `/metrics` mit Bearer-Token: Counters + Shard-Ping
+- [ ] Temp-Ban ablaufen → Unban + Case `UNBAN`
+
+### Bewusst offen
+
+- Musik- und KI-Modul (nur auf Zuruf)
+- Premium-Zahlungsanbindung
+- P4-UX (Server-Lock, Ban deleteMessageSeconds) bewusst nachgelagert
+
 ## Nächster geplanter Schritt
 
 - Deploy auf Traefik-Server manuell verifizieren; danach ggf. `deploy` → `main` mergen (nur auf Freigabe).
