 ## Phase 6 – WebUI-Fundament (Status: abgeschlossen, manuell bestätigt)
 
+- OAuth/Sessions, Settings-Framework, Layout, Modul-Toggles, Access-Rules
+- Login manuell bestätigt (`WEBUI_URL=http://10.111.0.65:3000`)
+
+## Phase 7 – WebUI Modul-Seiten + Owner-Panel (Status: implementiert, manuelle Tests ausstehend)
+
 ### Abgeschlossen
 
-- `apps/webui` als `@nexumi/webui` (Next.js 15 App Router, Tailwind 4, React 19)
-- Discord-OAuth2 + Redis-Sessions; Cookie-Fix für HTTP (`Secure` nur bei HTTPS; Set-Cookie am Redirect-Response)
-- Settings-Framework, Layout, Shared Zod-API, Modul-Toggles, Access-Rules, Dashboard-Audit
-- Deploy: bot+webui healthy; Login manuell bestätigt (`WEBUI_URL=http://10.111.0.65:3000`)
+- **Batch A:** Moderation, Automod, Logging, Welcome, Verification, Leveling, Economy, Fun + Prisma Owner-Modelle (`20260722190000_phase7_owner`)
+- **Batch B:** Tickets, Giveaways, SelfRoles, Tags, Starboard, Suggestions, Birthdays, TempVoice, Stats, Feeds, Scheduler, Backup, Commands-Seite, Overview-Aktivität; BullMQ-Anbindung WebUI↔Bot
+- **Batch C (Owner-Panel):** `/owner` Übersicht, Guilds (Leave/Blacklist), User-Blacklist, Feature-Flags, Presence (+ Bot-Job `presence` + Wartungsmodus in `routeCommand`), Team, Jobs/Migrationen, Changelog, Owner-Audit; Auth über `OWNER_USER_IDS` + `OwnerTeamMember`
+- Shared: `dashboard.ts`, `owner.ts` + Tests
+- Checks: shared 46 Tests, webui typecheck/lint, bot typecheck grün
 
-## Phase 7 – WebUI Modul-Seiten + Owner-Panel (Status: in Arbeit)
+### Manuell testen
 
-### Abgeschlossen (Batch A)
-
-- Prisma-Grundlage für Owner-Features: `CommandOverride`, `OwnerTeamMember`, `GlobalUserBlacklist`, `GuildBlacklist`, `FeatureFlag`, `BotPresenceConfig`, `ChangelogEntry`, `OwnerAuditLog` inkl. Migration `20260722190000_phase7_owner`
-- Shared Zod-Schemas für Dashboard-Module in `packages/shared/src/dashboard.ts` (Moderation, Automod, Logging, Welcome, Verification, Leveling, Economy, Fun, Cases, Warnings) + Tests
-- `OWNER_USER_IDS`-Env-Variable (WebUI-Env-Schema + `.env.example`), noch ohne Owner-Panel-Nutzung
-- API-Routen (GET+PATCH) für: `moderation`, `automod`, `logging`, `welcome`, `verification`, `leveling`, `economy`, `fun`; zusätzlich GET `cases` und `warnings`
-- Funktionierende Dashboard-Seiten (Formular + Speichern über SettingsForm/SaveBar, echte Daten, keine Platzhalter) für alle acht Batch-A-Module, inkl. Cases-Tabelle auf der Moderation-Seite
-- i18n-Keys `modulePages.*` in `de.json` und `en.json` ergänzt
-- Platzhalter-Route `dashboard/[guildId]/[module]/page.tsx` greift nur noch für die verbleibenden Batch-B/C-Module (Batch-A-Routen haben eigene Ordner mit Vorrang)
-- Verifiziert: `pnpm --filter @nexumi/shared build+test`, `pnpm --filter @nexumi/webui typecheck+lint`, `pnpm --filter @nexumi/bot typecheck+lint+test` grün; `next build` kompiliert und rendert alle Seiten (inkl. neue Batch-A-Routen) erfolgreich – einzige Auffälligkeit ist ein bekanntes Windows-only `EPERM`-Symlink-Problem bei `output: standalone` außerhalb von Docker, ohne Auswirkung auf den Linux-Container-Build
-
-### Abgeschlossen (Batch B)
-
-- Shared Zod-Schemas in `packages/shared/src/dashboard.ts` für alle restlichen Module ergänzt: Tickets (Config + Kategorien), Giveaways (+ Create/Action), SelfRoles, Tags, Starboard, Suggestions (Config + Liste + Action), Birthdays, TempVoice, Stats, SocialFeeds, Scheduler, GuildBackups, CommandOverrides, `ActivityStatSummary`, `KNOWN_COMMAND_NAMES` – inkl. neuer Tests in `dashboard.test.ts`
-- WebUI-BullMQ-Infrastruktur (`apps/webui/src/lib/queues.ts`): eigene `Queue`/`QueueEvents`-Instanzen für `giveaways`, `schedules`, `guild-backups`, `suggestions` (dieselben Queue-Namen wie im Bot), plus `addJobAndAwait`-Helper für bounded-wait auf Bot-Jobs
-- `BOT_TOKEN` zusätzlich im WebUI-Env-Schema (`apps/webui/src/lib/env.ts`) für schmale Discord-REST-Aufrufe (Guild-Backup-Snapshot) und BullMQ-Jobs
-- Bot-seitige Erweiterungen für Dashboard-Aktionen, die einen laufenden discord.js-Client brauchen:
-  - `giveaways`: neuer `giveawayCreate`-Job (`runGiveawayCreateJob`) für Dashboard-Erstellung, Worker in `apps/bot/src/jobs.ts` erweitert
-  - `suggestions`: neue Queue `suggestions` + Job `suggestionStatusUpdate` (`runSuggestionStatusUpdateJob`) für Dashboard-Staff-Actions (Approve/Deny/Consider/Implement inkl. Embed-Move + Autor-DM)
-  - `guildbackup`: Restore weiterhin über bestehende `guild-backups`-Queue (`restoreGuildBackup`), jetzt auch von der WebUI aus angestoßen
-- Modul-Configs (`apps/webui/src/lib/module-configs/*`) + API-Routen (`apps/webui/src/app/api/guilds/[guildId]/...`) + Formulare/Manager (`apps/webui/src/components/modules/*`) + Seiten/Loading (`apps/webui/src/app/dashboard/[guildId]/<href>/`) für: `tickets`, `giveaways`, `selfroles`, `tags`, `starboard`, `suggestions`, `birthdays`, `tempvoice`, `stats`, `feeds`, `scheduler`, `backup` (Href für `guildbackup`)
-  - Guild-Backup: Liste/Info/Download/Delete direkt über Prisma; Create via schmalem Discord-REST-Snapshot (`apps/webui/src/lib/guild-backup.ts`); Restore nur für den Discord-Server-Owner (Check über OAuth-Guild-Liste `guild.owner`), mit doppelter Bestätigung im UI
-  - Scheduler: Dashboard-Erstellung spiegelt exakt die Job-Optionen von `apps/bot/src/modules/scheduler/service.ts` (`schedule-{id}`-JobId, `scheduleSend`-Jobname, gleiche Queue) – kein separater Bot-seitiger Reconciler nötig
-- `/dashboard/[guildId]/commands` (CommandOverride-CRUD auf Basis von `KNOWN_COMMAND_NAMES`, Toggle + Cooldown + Rollen-/Kanal-Listen), Sidebar-Eintrag im Settings-Bereich ergänzt
-- Overview-Seite um 7-Tage-`ActivityStat`-Aggregate erweitert (Nachrichten, Voice-Minuten, aktive Mitglieder) via `apps/webui/src/lib/activity.ts`
-- Platzhalter-Route `dashboard/[guildId]/[module]/page.tsx` entfernt (alle Module haben jetzt eigene Ordner)
-- i18n-Keys `modulePages.*` für alle Batch-B-Module + `nav.commands` + `common.optional` + `dashboard.overview.activity*` in `de.json` und `en.json` ergänzt
-- Verifiziert: `pnpm --filter @nexumi/shared build+test`, `pnpm --filter @nexumi/webui typecheck+lint`, `pnpm --filter @nexumi/bot typecheck+lint+test` grün
-
-### Offen (Batch C)
-
-- Owner-Panel-UI (Übersicht, Guilds, User-Blacklist, Feature-Flags, Präsenz, Team, Jobs, Changelog, Audit) auf Basis der in Batch A angelegten Prisma-Modelle
-- Manuelle Tests der Batch-B-Seiten im laufenden Stack (Docker: bot + webui + Redis + Postgres), insbesondere: Giveaway-Create/End über BullMQ, Suggestion-Staff-Actions, Guild-Backup-Restore (Owner-Check), Scheduler-Job-Aufnahme durch den Bot-Worker
+1. `OWNER_USER_IDS=<deine Discord-User-ID>` in `.env` setzen, Stack neu starten
+2. Dashboard-Modul-Seiten speichern (Settings/Module/Cases etc.)
+3. Owner-Panel: `/owner` → Presence, Flags, Team, Jobs
+4. Giveaway/Suggestion/Backup-Aktionen aus dem Dashboard (BullMQ)
 
 ## Nächster geplanter Schritt
 
-- Batch C (Owner-Panel-UI) umsetzen, danach Phase 7 komplett manuell freigeben, anschließend Phase 8 (Landing, Status, Rechtsseiten).
+- Nach Freigabe Phase 8 (Landing Page, Status-Seite, Rechtsseiten-Gerüst).
