Verifiziert: useDeleteNotification und useAgentSkills haben NULL Komponenten-Importeure (nur Definitionsdateien). Die echten Komponenten nutzen andere Hooks (useNotifications, useMarkNotificationRead, useUnreadNotificationCount; useAgentTools/useAgentToolsFull). Nach AGENTS.md 0.2 keine Backend-Shims fuer tote Calls: beide Hooks entfernt, ungenutztes apiDelete-Import in notifications.ts bereinigt.
Damit sind alle 12 API-Braeche aus dem D5-Triage abgeschlossen: ai/sessions x5 (3e5f13f), policies x4 (86c96f0), mail x4 (86c96f0), notifications DELETE (hier), agents/skills (hier). tsc exit=0.
Root-Cause: Frontend-Komponenten (SignatureManager, LabelManager) rufen Endpunkte auf die das Backend nie hatte (404/405 in Production). Anders als ai/sessions sind diese Funktionen ECHT in Komponenten eingebunden -> Backend-Routen nachbestellt statt Frontend-Calls zu loeschen:
(1) PATCH+DELETE /mail/signatures/{id}: MailSignatureUpdate-Schema neu, Tenant-Scoped + Owner-Check (403 bei fremder Signatur), is_default-Exklusivitaet beim Setzen. (2) DELETE /mail/labels/{id}: gleicher Stil. (3) updateDraft Frontend: apiPatch -> apiPut (Backend hat PUT /drafts/{id} bereits). Beweistest tests/test_mail_sig_label_routes.py 5/5 gruen (PATCH-Werte, DELETE+Liste-leer, 404-Faelle).
Verifikation: create_app registriert beide neuen Routen (563 total); ruff clean; tsc exit=0.
Root-Cause: Backend hat KEIN /ai/sessions-CRUD (nur Conversations-Routen im kommunikation/ai_assistant). Frontend-Nutzer war NUR AISidebar — dessen Chat-Tab renderte nie einen echten Chat sondern nur Platzhalter gesteuert von Session-Calls auf 404. Nach AGENTS.md 0.2/0.3 keine Backend-Shims gebaut: (1) Geister-Tests ChatWindow.test.tsx + SessionList.test.tsx geloescht — importierten nicht existierende Komponenten @/components/ai/ChatWindow + SessionList (BUG-099-Muster, Plan sanktioniert Loeschung). (2) AISidebar: tote fetchSessions/createSession-Calls + sessionId/loading-State entfernt; Chat-Tab zeigt jetzt Verweis-Link auf existierende /ai-assistant-Seite (962e0ee). (3) api/ai.ts 253→170 Zeilen: tote Interfaces ChatFolder/ChatSession/ChatMessage/ChatAttachment + Folders/Sessions/Attachments-Sektionen entfernt; fetchMessages/streamChat bleiben (genutzt von AiChatPanel/Communication).
Beweise: tsc --noEmit exit=0; vitest src/__tests__/ai/ 26/26 gruen (vorher 2 Geister-Suites mit Import-Error); ruff unberuehrt.
- Complete rebuild of Tasks.tsx with 3-column explorer layout
- Left: TaskTree with status/priority grouping, expandable sections
- Middle: List view or Kanban board (switchable via toolbar)
- Right: TaskDetail panel with status selector, edit/delete actions
- PluginToolbar registration with new-task button and view-mode selector
- ResizablePanel for tree and detail columns
- Mobile responsive with single-pane view switching
- Search bar in list view
- Kanban board with 4 status columns (Offen, In Bearbeitung, Blockiert, Erledigt)
tsc clean
5.1: Toolbar already has PluginToolbar with navigation, view mode, actions — no changes needed
5.2: Calendar visibility toggle fix:
- calendarStore.setCalendars now initializes visibleCalendarIds with all calendar IDs
- CalendarTree.tsx visibility check simplified to visibleCalendarIds.has(cal.id)
- No more empty-set-means-all-visible confusion
tsc clean
Migration 0137: Drop AI chat tables (ai_chat_sessions, ai_chat_messages, ai_chat_attachments, ai_conversations, ai_messages)
Backend:
- Remove AIChatSession, AIChatMessage, AIChatAttachment models from ai_assistant/models.py
- Remove AIConversation, AIMessage from app/models/__init__.py
- Remove session/message/stream/attachment routes from ai_assistant/routes.py
- Add new streaming route POST /ai/conversations/{conversation_id}/stream using comm tables
- Add new messages route GET /ai/conversations/{conversation_id}/messages using comm tables
- Add stream_chat_comm, get_comm_messages, save_comm_message to services.py
- Update external_api.py to use CommConversation/CommMessage instead of AIChatSession/AIChatMessage
- Update unified_search ai_chat_provider to search comm_messages with conversation_type=ai
- Remove ai_copilot router from main.py and routes/__init__.py
- Remove ai_conversation from entity_permissions.py and owner_transfer_service.py
- Update ai_assistant/plugin.py get_entity_models to remove AIChatSession
- Guard ai_copilot_service.py imports with try/except
Frontend:
- Remove AIAssistant.tsx, AIAssistantStandalone.tsx, SessionList.tsx, ChatWindow.tsx
- Remove AI Assistant routes from routes/index.tsx
- Update api/ai.ts: streamChat uses /ai/conversations/{id}/stream, fetchMessages uses /ai/conversations/{id}/messages
- Update Communication.tsx: use convId for AI streaming, remove aiSessionId, use fetchAiMessages for AI conversations
- Update AiChatPanel.tsx: create comm conversation instead of AI session, use new fetchMessages
- Update AISidebar.tsx: remove ChatWindow import, show placeholder
tsc clean, build successful, backend import OK
Replace direct {error} JSX rendering with typeof check + .message fallback.
When error is an object (not a string), React showed [object Object].
Now renders error.message or fallback string.
