docs(progress): S1-Welle — F01+F02 (beide Astra-P0s) gefixt, deployed und live verifiziert

Vorher: Ein Mandanten-Admin (users:write) konnte die globale User.email
und das Passwort JEDES Mitglieds seines Mandanten aendern. User ist
aber mandantenuebergreifend — derselbe Datensatz traegt Passwort und
Systemadmin-Flag; der Passwort-Reset nutzt die veraenderbare Adresse.
Ein Admin aus Mandant A konnte so die globale Reset-Adresse eines
gemeinsamen Benutzers umlenken (Astra-Repro: globale Feldaenderung
isoliert reproduziert).

Fix (routes/users.py update_user):
- email/new_password fuer FREMDE User -> 403 global_identity_forbidden
  (nur Selbstservice oder echter System-Admin)
- is_active fuer MEHRMANDANTEN-User durch Tenant-Admin -> 403
  multi_tenant_status_forbidden (Deaktivierung waere global sperrend;
  Single-Mandanten-Mitglieder duerfen wie bisher deaktiviert werden)
- is_system_admin-Eskalationscheck unberuehrt (war schon korrekt)

Abnahme (Astra): Ein Tenant-Verwalter kann weder die globale E-Mail-
Adresse noch den globalen Aktivstatus eines gemeinsamen Benutzers
veraendern — erfuellt.

Tests: test_user_service.py 13/13 (5 neue F02-Tests: fremde E-Mail 403,
fremdes Passwort 403, Mehrmandanten-Deaktivierung 403, Name-Aenderung
bleibt 200, Selbstservice bleibt 200). ruff clean.

+
+### Standard-Layout (Referenz: ContactsList.tsx)
+
+Alle Explorer-Plugins nutzen das 3-Spalten-Layout aus den UI-Design-Guidelines:
+
+```
+┌─────────────┬──────────────────┬──────────────────────┐
+│   Tree      │   Liste/Ansicht   │   Detail             │
+│  (224px)    │   (flex-1)        │   (flex-1 / 60%)     │
+│ ResizablePanel│  ResizablePanel   │   ResizablePanel     │
+└─────────────┴──────────────────┴──────────────────────┘
+```
+
+- **Toolbar oben:** PluginToolbar mit Filter-Dropdowns, Ansichts-Umschaltern, Aktion-Buttons
+- **Linke Spalte:** ResizablePanel mit Baumansicht (Ordner, Kategorien, Kalender)
+- **Mitte:** Liste, Karten, Kalender-Ansicht — mehrere Ansichten umschaltbar
+- **Rechts:** Detail-Bereich für ausgewähltes Element
+
+---
+
+### Phase 1: Echte Bugs fixen (2-3 Tage)
+
+#### 1.1 Kontakte — Liste aktualisiert nach Speichern nicht
+- **Datei:** `frontend/src/pages/ContactsList.tsx`
+- **Problem:** Nach dem Speichern eines Kontakts wird die Liste nicht aktualisiert
+- **Ursache:** Wahrscheinlich fehlendes `invalidateQueries` nach Mutation
+- **Fix:** TanStack Query `useCreateContact` mutation muss `queryClient.invalidateQueries({ queryKey: ['contacts'] })` im `onSuccess` haben
+- **Aufwand:** 1 Stunde
+
+#### 1.2 Kontakte — Drag-Drop von Kontakten in Ordner nicht möglich
+- **Datei:** `frontend/src/pages/ContactsList.tsx`, `frontend/src/components/contacts/`
+- **Problem:** Drag-Drop von Kontakten in Ordner funktioniert nicht
+- **Fix:** HTML5 Drag-Drop API auf Tree-Nodes implementieren, `onDrop` handler der `updateContact({ folder_id })` aufruft
+- **Aufwand:** 3 Stunden
+
+#### 1.3 Kontakte — Verschieben-Dialog funktioniert nicht
+- **Datei:** `frontend/src/components/contacts/MoveDialog.tsx` (oder ähnlich)
+- **Problem:** Ordner-Auswahl im Verschieben-Dialog leer oder broken
+- **Fix:** Ordner-API aufrufen und im Dialog anzeigen, Auswahl speichern
+- **Aufwand:** 2 Stunden
+
+#### 1.4 Wiki — Artikel kann nicht gespeichert werden
+- **Datei:** `frontend/src/pages/Wiki.tsx`, `frontend/src/api/knowledge.ts`

+- **Fix:** Je nach Diagnose — API-Fehler oder Frontend-Mutation-Fehler
+- **Aufwand:** 2 Stunden
+
+#### 1.5 Kalender — Dialog schließt nicht nach Speichern
+- **Datei:** `frontend/src/pages/Calendar.tsx`, `frontend/src/components/calendar/AppointmentEditForm.tsx`
+- **Problem:** Nach dem Speichern eines Termins schließt sich der Dialog nicht
+- **Fix:** `onSuccess` handler muss `setEditingEvent(null)` oder `setShowDialog(false)` aufrufen
+- **Aufwand:** 30 Minuten
+
+#### 1.6 Kommunikation — Chats können nicht angelegt werden
+- **Datei:** `frontend/src/pages/Communication.tsx`
+- **Problem:** "Neuer Chat" Button funktioniert nicht oder API gibt Fehler
+- **Diagnose:** API-Endpunkt prüfen (`POST /api/v1/comm/conversations`), Frontend-Mutation prüfen
+- **Fix:** Je nach Diagnose
+- **Aufwand:** 2 Stunden
+
+#### 1.7 Wiki — Doppelt im Menü
+- **Datei:** `frontend/src/routes/index.tsx`, `frontend/src/components/layout/` (Navigation)
+- **Problem:** Wiki erscheint zweimal im Menü

+#### Problem
+Der AI Assistent ist ein paralleles System das die Kommunikation-Plattform dupliziert:
+- **AI Assistant Tabellen:** `ai_conversations`, `ai_messages` (app/models/ai_conversation.py) + `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` (app/plugins/builtins/ai_assistant/models.py) — 5 Tabellen
+- **AI Assistant Frontend:** `AIAssistant.tsx`, `AIAssistantStandalone.tsx`, `SessionList.tsx`, `ChatWindow.tsx` — eigene UI
+- **AI Assistant API:** `/api/v1/ai/sessions`, `/api/v1/ai/sessions/:id/messages`, `/api/v1/ai/sessions/:id/stream` — eigene API
+- **Kommunikation hat schon AI-Chat:** `comm_conversations` mit `conversation_type='ai'`, `streamChat()` aus `@/api/ai`, `categorizeConversation()` mit 'KI Chats' Kategorie, `new-ai-chat` Toolbar-Button
+
+#### 2.1 Daten-Migration (Backend)

+  - `ai_chat_messages.session_id` → `comm_messages.conversation_id`
+  - `ai_chat_messages.role` → `comm_messages.sender_type` ('user' → 'user', 'assistant' → 'ai')
+  - `ai_chat_messages.content` → `comm_messages.content`
+  - `ai_chat_messages.tenant_id` → `comm_messages.tenant_id`
+- **Migration 0137:** Migriere `ai_conversations` → `comm_conversations` (falls Daten vorhanden)
+- **Migration 0137:** Migriere `ai_messages` → `comm_messages` (falls Daten vorhanden)
+- **Migration 0137:** Drop `ai_conversations`, `ai_messages`, `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` Tabellen
+- **Aufwand:** 1 Tag
+
+#### 2.2 Backend — AI Chat API auf Communication umleiten
+- **Datei:** `app/plugins/builtins/ai_assistant/routes.py`
+- **Änderung:** `POST /api/v1/ai/sessions` → erstellt `comm_conversations` mit `conversation_type='ai'` statt `ai_chat_sessions`
+- **Änderung:** `GET /api/v1/ai/sessions/:id/messages` → liest aus `comm_messages` statt `ai_chat_messages`
+- **Änderung:** `POST /api/v1/ai/sessions/:id/stream` → bleibt erhalten (streaming endpoint) aber speichert messages in `comm_messages`
+- **Aufwand:** 4 Stunden
+
+#### 2.3 Frontend — AI Assistant Page entfernen

+- **Navigation:** AI Assistent Menüpunkt entfernen, AI Chat bleibt unter Kommunikation
+- **Aufwand:** 2 Stunden
+
+#### 2.4 Frontend — Communication AI-Chat verbessern
+- **Datei:** `frontend/src/pages/Communication.tsx`
+- **Änderung:** AI Chat Sessions aus `comm_conversations` laden (statt `ai/sessions` API)

+- **Behalten:** `ai_assistant` plugin routes für Settings (providers, models, presets)
+- **Aufwand:** 2 Stunden
+
+#### 2.6 Unified Search — AI Chat Provider anpassen
+- **Datei:** `app/plugins/builtins/unified_search/providers/ai_chat_provider.py`
+- **Änderung:** Search auf `comm_messages` (conversation_type='ai') statt `ai_chat_messages`

+2. **Phase 9** (Strukturelle Änderungen) — schnell, wenig Aufwand
+3. **Phase 5** (Kalender) — kleines Update, baut auf Phase 1 auf
+4. **Phase 2** (AI Assistent → Kommunikation) — entfernt paralleles System, baut auf Phase 1.6 auf
+5. **Phase 6** (Tags) — unabhängig, Backend + Frontend
+6. **Phase 4** (Tasks) — großer Umbau, unabhängig
+7. **Phase 3** (Wiki) — größter Umbau (WYSIWYG Editor), baut auf Phase 1 auf

+
+#### Was ich NICHT tun werde:
+- Keine Massen-Scripts die neue Fehler verursachen
+- Keine Änderungen ohne Verifizierung gegen Produktion
+- Keine neuen Plugins wenn bestehende erweitert werden können
+- Keine neuen Pages wenn bestehende umgebaut werden können
+- Jede Änderung wird mit tsc und API-Test verifiziert
+
+#### Was ich brauche:
+- **IMAP-Zugangsdaten:** Für Mail-Postfach-Test (Phase 9.2)

 *Diese Roadmap basiert auf dem Endstand-Audit des aktuellen Code-Archivs und der gemeinsamen Detail-Review. Ziel bleibt: keine unnötigen Universalmodelle, keine Massenrefactorings und keine parallelen Mechanismen. Gemeinsame technische Kerne werden dort genutzt, wo Semantik wirklich gleich ist; fachliche Speziallogik bleibt erlaubt. Bestehender funktionierender Code wird respektiert. Die eingebauten Privacy-/AI-Compliance-Funktionen schaffen technische Voraussetzungen und Nachweise; die rechtliche Konformität eines konkreten Deployments/Branchenplugins hängt zusätzlich von dessen tatsächlichem Zweck, Datenverarbeitung, Betreiberrolle und organisatorischen Maßnahmen ab.*

+
+## Phase L — Dokumente-Generator ✓ ABGESCHLOSSEN (2026-08-29/30, Commits b311ab7 + 559bba6, deployed, Health healthy, Alembic 0143)
+
+**Ziel:** Zentrale Dokument-Generierung mit Briefpapier + dynamischen Blöcken, Drag/Drop-Editor, KI-Steuerung, E-Rechnung-Fähigkeit. Module registrieren ihre Blöcke als Contribution (Contract-Muster wie Import/Export).
+
+**Basis:** report_generator-Plugin (Jinja2-Templates, pdf_generator.py, Background-Jobs, ReportTemplate/ReportInstance-Models) — Erweiterung statt Neubau.
+
+### L1 — Block-System (2-3 Tage)
+- Briefpapier-Modell (pro Tenant: Logo, Header/Footer, CSS)
+- Block-Modell (typ: text/table/chart/placeholder, order, content)
+- Block-Registrierung durch Module via Contract (`document_blocks` wie `importexport_entities`)
+- print_templates-Tabelle (Briefpapier-Ref + Block-Komposition)
+
+### L2 — Drag/Drop-Editor (3-5 Tage)
+- Frontend: Block-Palette (registrierte Blöcke des Moduls), Canvas, Platzierung
+- Placeholder-Editor (`{{firstname}}`, `{{company.logo}}`)
+- Live-Preview
+
+### L3 — Renderer-Integration (1-2 Tage)
+- report_generator-Engine an Block-Komposition anbinden
+- Jinja2-Templates aus Block-Komposition generieren
+- PDF/Excel/CSV-Output über bestehende Engine
+
+### L4 — KI-Steuerung (1-2 Tage)
+- „Erstelle Rechnungsvorlage" via AI-Module (agent_loop existiert)
+- Template-Vorschläge aus Block-Komposition
+
+### L5 — E-Rechnung (2-3 Tage)
+- XRechnung/ZUGFeRD-Format (Verkauf-Modul registriert Rechnungs-Blöcke)
+- Klären: Steuer-Behörden (Deutschland, B2B-Pflicht ab 2027) oder Kunden-Lieferungen?
+
+**Abhängigkeiten:** L5 benötigt Phase F (Agents) und das Verkaufs-Modul (noch nicht gebaut).

+**Verwandte Issues:** #359 (Import/Export Contribution — gleiche Plugin-Philosophie).
+
+---
+
+## Phase M — MiniApp-Plattform & Dashboard-Builder (geplant, user-abgestimmt 2026-08-29)
+
+**Ziel:** MiniApps als universelles, teilbares UI-Baustein-System über alle Hosts (Chat, Dashboard, Windows, AI-Agenten). Dashboard-Builder mit Edit-Modus, Drag&Drop, Resize, Tabs und pro-Widget-Settings. System-Dashboard-Teile werden zurück in Plugins gebaut (Core wird zum reinen Host).
+
+**Basis (Live-Bestand 2026-08-29):**
+- `kommunikation/miniapp_registry.py` (92 Z., MiniAppDef mit register/unregister/unregister_plugin — inkl. Lifecycle-Cleanup)
+- `MiniAppContribution` im Manifest-Schema (app_id, name, icon, description, render_schema) — **LÜCKE: kein permission-Feld**
+- `FrontendDashboardWidget` im Manifest (id, component, col_span, row_span, permission) — **LÜCKE: kein settings_schema**
+- `MiniAppBlock.tsx` als comm-Block-Typ (Chat-Host — fertig verdrahtet)
+- `DashboardGrid`/`DashboardWidgetLoader` + 4 Widgets (RecentContacts, TasksSummary, CalendarUpcoming)
+- Dashboard.tsx (170 Z.) mit hardcodierten StatCards (via contacts-Contract `get_counts`), ActivityFeed (via Audit-Log), System-Metrics (Admin-only) — **Rückbau-Bestand**
+- `app/routes/dashboard.py` listet manifest `dashboard_widgets` (bereits permission-agnostisch, nur `dashboard:read` auf Endpoint-Ebene)
+- @dnd-kit (core/sortable/utilities) bereits im Projekt (Referenz: SettingsMenuOrder, Dokumente-BlockEditor)
+- windowStore (Window-Manager) existiert für spätere Hosts
+
+**Architektur-Entscheidung (user-bestiätigt):** EINE Universal-Registry statt zweier paralleler Systeme — `dashboard_widgets` wird Alias von `miniapps`; jedes Plugin/System registriert MiniApps via Contribution (gleiches Muster wie settings_pages/print document blocks, #359-Philosophie). Ein Host-Set: Chat-Block (fertig), Dashboard (neu), Windows (M6), AI-Agenten-Tool-Ausgabe (M6).
+
+
+**⚠️ Abgrenzung Workspace ≠ Dashboard (user-korrigiert 2026-08-30):**
+- **Dashboard (diese Phase M)** = PERSÖNLICH: jeder User baut eigene Dashboards (Layout/Tabs/Instanzen) — Speicher ist die NEUE `dashboards`-Tabelle (owner-basiert). NIEMALS `workspace_widgets` dafür verwenden.
+- **Workspace (Phase N)** = ADMIN-Kontext für Gruppen: welche Module sichtbar sind (fertig) + Modul-Teilmengen (Scopes) + welche Widget-TYPEN der Workspace anbietet (`workspace_widgets`, existiert bereits — Workspace-Eigentum).
+- Schnittstelle: der aktive Workspace begrenzt nur die VERFÜGBAREN Widget-Typen; das persönliche Layout bleibt User-Eigentum und wird von keinem Workspace überschrieben.
+
+
+### M1 — Universal-MiniApp-Registry (2-3 Tage)
+- miniapp_registry aus kommunikation-Plugin in Plugin-Layer heben (Plattform-Konzept, kommunikation behält Chat-Hosting)
+- MiniAppDef/MiniAppContribution erweitern: `permission` (Pflicht-Feld, fail-closed), `settings_schema` (generisches Settings-Form), `col_span`/`row_span`, `min_size`
+- `dashboard_widgets` (Manifest) → Alias von `miniapps` (Rückwärtskompatibilität, ein Contribution-Typ)
+- `/api/v1/miniapps`-Endpoint: Registry-Listing **server-seitig permission-gefiltert** (nur MiniApps sichtbar, für die der User die Permission hat)
+- Host-Rendering prüft Permission zusätzlich beim Render (Defense-in-Depth wie Plugin-Routen)
+- Lifecycle: Plugin-Deaktivierung → unregister_plugin → Widgets verschwinden aus allen Hosts
+
+### M2 — Dashboard-Backend (2-3 Tage)
+- `dashboards`-Tabelle: pro User mehrere Dashboards, Tabs, Layout als JSONB (`[{tab, widgets: [{app_id, settings, col, row, span}]}]`), RLS fail-closed + crm_api-Policy (0084-Muster)
+- CRUD-Endpoints (list/create/update/delete + set-default), Tenant-Scoping, Owner-only oder Admin
+- Dual-Path: Plugin-SQL idempotent + Alembic-Konvergenz (Gate-B-Muster wie 0143)
+- Default-Dashboard-Seed beim ersten Aufruf (aus Registrierungs-Order abgeleitet)
+
+### M3 — Dashboard-Builder-Frontend (3-5 Tage)
+- Edit-Modus als Modus-Schalter: aktiv → Widgets hinzufügen/entfernen, Größe ändern (col/row-span), Einstellungen; beenden → persistiertes Layout, reine Ansicht
+- Drag&Drop-Grid (@dnd-kit, Referenz BlockEditor/SettingsMenuOrder): Platzierung + Umsortieren
+- Widget-Palette: verfügbare MiniApps (aus `/api/v1/miniapps`, permission-gefiltert), Suche/Kategorie
+- Generisches Settings-Form pro Widget aus `settings_schema` (gleiche Philosophie wie Block-Config-Panels beim Dokumente-Editor)
+- Tabs: mehrere Dashboards pro User, Tab-Verwaltung im Edit-Modus
+- Dashboard.tsx wird zum reinen Host (keine hardcodierten Inhalte mehr)
+
+### M4 — System-Rückbau (2-3 Tage)
+- StatCards (Firmen-/Kontakt-Zähler via contacts-Contract) → contacts-Plugin-MiniApp
+- Aktiv-diese-Woche/Neu-diesen-Monat + ActivityFeed (Audit-Log) → audit/auditlog-MiniApp
+- System-Metrics-Block (DB/Redis/Worker/LLM-Kosten, Admin) → System-MiniApp mit `settings:read`-Permission
+- Bestehende Dashboard-Widgets (RecentContacts, TasksSummary, CalendarUpcoming) zu MiniApps migrieren (gleiches Format, dann Chat-fähig)
+
+### M5 — Plugin-MiniApps (2-3 Tage)
+- contacts, tasks, calendar, wiki, dms, mail, knowledge (Graph-RAG), automation liefern jeweils MiniApps via Manifest-Contribution
+- Jede MiniApp automatisch überall verfügbar: Chat senden + Dashboard platzieren
+- Permission je MiniApp passend zum Owner-Modul (z.B. `tasks:read` für TaskSummary)
+
+### M6 — Weitere Hosts (2-3 Tage)
+- AI-Agenten-Tool: Agent kann MiniApp als Ausgabe-Block in Chat-Antwort einbetten (miniapp-Block-Typ existiert, Tool-Registry erweitern)
+- Windows (windowStore): MiniApp per Klick/Expand in eigenem Fenster öffnen
+- Evaluiert: Wiki-Einbettung (BlockRenderer-Muster) — nur wenn Bedarf bleibt
+
+**Abhängigkeiten:** M3 benötigt M1+M2. M4/M5 nach M3 (Host muss stehen). M6 zuletzt.
+
+**Verwandte Phasen/Issues:** Phase L (Gleiche Contribution-Philosophie), #359 (Contract-Muster), Phase F (Agenten für M6).
+
+---
+
+## Phase N — Workspace-Scopes: Modul-Teilmengen pro Arbeitskontext (geplant, user-abgestimmt 2026-08-30)
+
+**Ziel:** Workspaces werden zu voll anpassbaren Arbeitskontexten: jedes Modul kann pro Workspace auf eine Teilmenge eingeschränkt werden (z.B. nur Kontakt-Ordner X+Y, nur DMS-Ordner „Angebote", nur Mail-Postfach vertrieb@, nur Kalender „Vertrieb"). Admin-definiert für zugewiesene User-Gruppen — klar getrennt vom persönlichen Dashboard (Phase M).
+
+**Klare Trennung (user-korrigiert):**
+- Workspace = Admin-Kontext, Gruppen-Feature: WAS ist sichtbar/verfügbar (Module, Teilmengen, Widget-Typ-Angebot via `workspace_widgets`)
+- Dashboard = persönlich, User-Feature: WIE ICH mein Dashboard baue (Phase M, `dashboards`-Tabelle)
+- Beide Systeme berühren sich NUR an einer Schnittstelle: der aktive Workspace begrenzt das Widget-Typ-Angebot; das persönliche Layout bleibt unberührt.
+
+**Basis (Live-Bestand, 0 Umbau):**
+- `workspace_modules.config` (JSONB) — existiert, ungenutzt → Scope-Speicher pro Modul
+- `X-Workspace-ID` Header + API-Client-Interceptor (pro Tab) — existiert, wird vom Backend gelesen
+- `/api/v1/workspaces/context` — existiert, liefert Modul-Konfiguration aus
+- Sidebar filtert bereits live (isModuleVisible — Consumer-Beweis)
+- 17/17 Workspace-Tests grün, RLS auf allen 4 Tabellen
+- Contract-Muster für die Scope-Registry (wie document_placeholders)
+
+**Security-Invariante:** Scope = reine UND-Einschränkung. Sichtbarkeit = Workspace-Scope ∧ RLS ∧ ABAC ∧ Permissions. Ein Workspace kann NIE mehr sichtbar machen, nur weniger. Ohne aktiven Workspace = kein Filter (rückwärtskompatibel, wie Sidebar).
+
+### N1 — Scope-Registry via Contract (2 Tage)
+- Plugins deklarieren `workspace_scopes()` → verfügbare Scope-Dimensionen + Wertequellen (z.B. „folder_ids, Multiselect, via /contacts/folders")
+- `/context` liefert `config` der Module mit aus; Scope-Definitionen-Endpoint für den Editor
+
+### N2 — Dynamischer Scope-Editor (2-3 Tage)
+- WorkspaceManager: pro Modul automatisches Filter-UI aus der Registry (Multiselects für Ordner/Postfächer/Kalender, Toggles, Standard-Ansichten)
+- Speicherung in `workspace_modules.config`
+
+### N3 — Erste vier Module integrieren (2-3 Tage)
+- Contacts: Ordner-Teilmengen, Firmen/Personen-Filter, Standard-Saved-View
+- DMS: Ordner-Teilmengen, Datei-Typ-Filter
+- Mail: Postfach-Teilmengen
+- Calendar: Kalender-Teilmengen, Standard-Ansicht
+- Backend respektiert X-Workspace-ID bei Listen (additive Filter-Logik, kein Umbau bestehender Routes)
+
+### N4 — Restliche Module (2-3 Tage)
+- Tasks (Boards/Listen, „nur meine"), Kommunikation (Räume), Wiki (Kategorien), Reports/Dokumente (Vorlagen), Automation (Agenten), Tags, Suche (Provider), Navigation (Menü-Reihenfolge, Startseite pro Workspace)
+- Dashboard-Schnittstelle: workspace_widgets bestimmt verfügbare Widget-TYPEN pro Workspace (Admin) — persönliches Layout bleibt Phase M
+
+**Abhängigkeiten:** unabhängig von Phase M. N3/N4 nach N1+N2.
+
+---
+
+## Phase P — Notizen-App (Notion-artig, ersetzt das Wiki komplett) (geplant, user-abgestimmt 2026-08-30)
+
+**Ziel:** Aus dem Wiki wird eine Notion-artige Notizen-/Firmen-Wissen-App: Seiten-Baum (beliebig tief, statt flacher Kategorien), Inline-Block-Editor mit Slash-Menü und Drag&Drop, Quer-Verweise zwischen Seiten, MiniApp-Einbettung, vollständige Such-Indexierung. Das alte Wiki wird KOMPLETT ersetzt (keine Legacy-App parallel).
+
+**User-Entscheidungen (2026-08-30):**
+- Keine Notion-Datenbanken zunächst — stattdessen MiniApps als einbettbare Blöcke (Phase M-Synergie)
+- Später: Plugin-Erweiterbarkeit (eigene Block-Typen via Contract), evtl. Datenbank-Block als Plugin nachlieferbar
+- Vollständige Such-Indexierung ist PFLICHT (Notizen/Firmen-Wissen auffindbar)
+- Quer-Verweise (Seiten verlinken Seiten)
+
+**Edit-Konzept (Notion-Recherche 2026-08-30):** Notion hat KEINEN separaten Bearbeitungsmodus — "all content is editable by default": Klick in die Seite = tippen, Auto-Save im Hintergrund, Slash-Menü für Block-Typen. Confluence macht stattdessen Draft/Publish-Workflow. Für uns: Live-Inline-Editing wie Notion als Standard; der "Lese-Modus" entsteht natürlich über Permissions (nur-Lesen = gerenderte Seite ohne Editierfunktion) + optional Page-Lock. Kein Mode-Toggle im UI nötig.
+
+**Basis:** Wiki-Plugin (486 Z. Backend: WikiCategory/WikiArticle/WikiArticleVersion + 10 Endpoints) wird erweitert, nicht neu gebaut. Block-Muster aus Phase L (JSONB {id, type, config}), dnd-kit vorhanden, Custom-Field-Engine für spätere Properties, Entity-Links für CRM-Quer-Verweise vorhanden. Unified Search: Provider-Registry + BaseSearchProvider (Embeddings + hybrid FTS/vector) + chunking existieren — die App liefert Provider + Re-Index-Hook.
+
+### P1 — Datenmodell & Migration (2 Tage)
+- WikiArticle → WikiPage: `blocks JSONB` (statt content Text), `parent_id` (Seiten-Hierarchie statt Kategorien), `icon`, `is_favorite`, **`is_locked` (Page-Lock, user-entschieden 2026-08-30)**; Quer-Verweise als Block-Typ page_link
+- Migration: Markdown-Artikel → Text-Blöcke, Kategorien → Eltern-Seiten, Versionen (WikiArticleVersion) bleiben erhalten
+- Dual-Path: Plugin-SQL idempotent + Alembic-Konvergenz (Gate-B-Muster)
+
+### P2 — Sidebar mit Seiten-Baum (2 Tage)
+- Notion-artiger Baum: Seiten anlegen/umbenennen/löschen, Drag&Drop-Umsortierung (dnd-kit), + Button, Kontextmenü, Favoriten, Seitensuche
+- Ersetzt die alte Kategorien-Navigation komplett
+
+### P3 — Inline-Block-Editor (4-5 Tage) — Herzstück
+- Live-Inline-Editing (Klick = tippen, kein Mode-Toggle), Auto-Save debounced in blocks JSONB
+- Slash-Menü: „/" → Block-Typ-Auswahl
+- Block-Typen: Text, H1-H3, To-do, Toggle (auf/zu), Quote, Callout, Code, Divider, Bild, Page-Link (Quer-Verweis mit Auto-Vervollständigung), MiniApp
+- Drag&Drop-Block-Umsortierung (dnd-kit, Phase-L-Erfahrung)
+- **Page-Lock (user-bestaetigt 2026-08-30):** `is_locked = true` = Seite nicht editierbar (auch mit wiki:write). Backend lehnt Block-Updates mit 409 `page_locked` ab; Frontend zeigt rein gerenderte Seite + Schloss-Badge; Lock setzen/loeschen nur Owner oder Admin (Lock-Button in der Seitentoolbar); gelockte Seiten bleiben fuer Search/Versionen/Kommentare normal indexiert
+
+### P4 — MiniApp-Blöcke + Plugin-Erweiterbarkeit (1-2 Tage)
+- „/ MiniApp"-Block-Typ: registrierte MiniApps in Seiten rendern (erster MiniApp-Konsument neben Chat — treibt Phase M mit)
+- Contract `wiki_blocks()`: Plugins melden eigene Block-Typen für den Editor an (Muster document_blocks) — Basis für späteren Datenbank-Block
+
+### P5 — Vollständige Such-Indexierung (1-2 Tage)
+- Content-Extraktion aus Blöcken (Text/Überschriften/To-do/Callout) → content_tsv + Embedding-Chunks (chunking.py)
+- WikiPage-Search-Provider an unified_search (hybrid FTS + vector, Re-Index bei jedem Auto-Save)
+- Suchergebnis verlinkt direkt auf Seite + Sprungmarke
+
+**Abhängigkeiten:** P4 benötigt M1 (Universal-Registry). P1-P3, P5 unabhängig startbar.
+
+## Phase Q — Frontend-Plugin-Architektur ✓ ABGESCHLOSSEN (2026-09-13, Commits 895f85d + b666fe5, deployed, Health healthy)
+
+> **Umgesetzt am selben Tag wie geplant.** Q3 (Generator + PluginLoader) + Q4 (MiniAppHost)
+> in 895f85d; Q1 (statische Plugin-Routen entfernt) + Q2 (Settings-Routen + Renderer-Variante)
+> in b666fe5. Details und Live-Beweise: PROGRESS.md Phase-Q-Section.
+
+
+**Ziel:** Die letzten verbliebenen Plugin-Grenzverletzungen im Frontend beseitigen — ein Plugin soll sein Backend, Manifest UND React-Seite liefern können, ohne dass zentrale Frontend-Dateien angefasst werden müssen. Basis: externes Architektur-Audit (2026-09-13), dessen Backend-Punkte bereits gefixt sind (siehe PROGRESS.md „Externer Architektur-Audit"); die vier Frontend-Punkte sind bewusst als eigene Phase geplant, weil sie ein durchdachtes Build-Time-Discovery-Konzept erfordern (Vite kann dynamische Imports zur Laufzeit im Production-Bundle nicht zuverlässig auflösen).
+
+### Q1 — Statische Plugin-Routen aus routes/index.tsx entfernen (Doppel-Architektur)
+- Status quo: `/calendar`, `/dms`, `/mail`, `/reports`, `/tasks`, `/communication`, `/workflows`, `/import-export`, `/wiki`, `/agents`, `/automation` sind statisch im zentralen Router eingetragen UND kommen gleichzeitig über die Plugin-Manifeste via PluginRouteRenderer.
+- Ziel: Nur noch PluginRouteRenderer bedient Plugin-Seiten; statische Einträge nur für echte Core-Seiten (Dashboard, Settings-Shell, Login, Trash, Approvals bis Core-Migration).
+- Risiko: Manifest-Routen müssen Permissions, Layout-Einbindung (AppShell-Children vs. eigenständig) und Ladezustände 1:1 abbilden.
+
+### Q2 — Statische Settings-Routen ausdünnen
+- Status quo: settings/roles, users, groups, mail, notifications, ai, ai-proactive, automation, documents sind statisch UND via settings_pages der Manifeste vorhanden.
+- Ziel: settings_pages (Manifest) wird einzige Wahrheit für Plugin-Settings-Seiten; statische Einträge nur für Core-Settings (theme, system, backup, webhooks, menu, workspaces).
+
+### Q3 — STATIC_COMPONENT_MAP ersetzen durch Build-Time-Discovery
+- Status quo: PluginLoader.tsx hält eine zentrale Komponenten-Liste (~26 Einträge). Ein neues Plugin muss die Leo-Frontend-Codebasis anfassen.
+- Ziel: Build-Skript scannt app/plugins/builtins/*/plugin.py auf FrontendPageRoute/SettingsPage/Component-Pfade und generiert automatisch eine Import-Map (generated, committet), die Vite statisch chunken kann. Keine manuelle Zentral-Liste mehr.
+
+### Q4 — widgetRegistry in MiniAppHost durch generierte Map ersetzen
+- Status quo: 11 Widget-Komponenten sind zentral hardcodiert (RecentContactsWidget, TasksSummaryWidget, ...).
+- Ziel: Q3-Mechanismus deckt auch dashboard_widgets/miniapps component-Pfade ab; MiniAppHost nutzt dieselbe generierte Import-Map.
+
+**Reihenfolge (wie umgesetzt):** Q3 → Q1/Q2 → Q4 (Q4 fiel mit Q3 mit, da MiniAppHost dieselbe generierte Map nutzt). Jeder Schritt mit Vitest-Sicherung der betroffenen Seiten und Production-Build-Verifikation (Chunk-Existenz prüfen).
+
+## Externaudit Astra 2026-09-17 (41 Findings) — Sanierung PHASE S (bestätigt, NÄCHSTE PHASE, vor/neben R)
+
+**Auditergebnis:** 2 P0 (KI führt nicht freigegebene Tools aus; Mandantenverwaltung kann globale Anmeldeidentitäten ändern), 29 P1, 10 P2. Geprüft am vollständigen Stand ee5545d (ZIP). Interne Verifikation am 2026-09-17: 10 Findings stichprobenartig am Code nachgelesen (F01, F02, F05, F08, F10, F12, F17, F24, F37, F41) — **alle 10 korrekt**. Übrige Findings: detailliert mit Zeilennummern belegt, Detail-Verifikation erfolgt jeweils bei Umsetzung. Volltext des Audits: [docs/audits/astra-audit-2026-09-17.md](docs/audits/astra-audit-2026-09-17.md); Kernpunkte je Finding in den Wellen-Issues.
+
+**Strukturdiagnose (Astra):** Mehrere Stellen verwalten denselben Zustand (Plugin-Aktivität, Schema); Contracts garantieren zu wenig Verhalten; API- und Worker-Ausführung nicht gleichwertig; Berechtigungsprüfungen liegen zu weit vom Seiteneffekt entfernt; Statusanzeigen teils von tatsächlicher Funktion entkoppelt. — Bestätigt und deckt sich mit den realen Incidents (#389 Plugin down 4 Wochen, #380 158 Events failed).
+
+**Sanierungswellen (Reihenfolge nach Risiko, an Astra-Empfehlung angelehnt):**
+
+### Welle S1 — Sicherheitsgrenzen (P0 + Auth/Permission-Kette) — ZUERST
+- **F01 (P0)** agent_loop._execute_tool: Tool-Ausführung ohne Allowlist- und Permission-Check — unmittelbar vor Handleraufruf prüfen: Tool in der dem LLM angebotenen Liste, required_permission gegen aktuelle User-Rechte, Verbote, Mandant, Plugin aktiv, ggf. Approval. Abnahme: nicht angebotenes Tool → Ablehnung, Handler bleibt null.
+- **F02 (P0)** users.py update_user: globale User.email durch Mandanten-Admin (users:write) änderbar → globale Identitätsänderungen (email, is_system_admin global, Passwort) von Mandantenverwaltung trennen; nur Selbstservice oder echte globale Admin. Abnahme: Tenant-Admin kann globale E-Mail/Aktivstatus fremder Mandanten-Mitglieder nicht ändern.
+- **F10** require_permission: Token-Scopes ersetzen User-Rechte (early-return) → effektive Rechte = Schnittmenge(User, Token-Scopes, Delegation), Verbote vorrangig. Abnahme: Token mail:write + User ohne mail:write → 403.
+- **F05** require_active_plugin läuft vor Auth/ohne Mandantenkontext → Plugin-Gate an authentifizierten Kontext binden, fehlender Kontext = ablehnen. Abnahme: mandantendeaktiviertes Plugin → 403 auch bei gültiger Session.
+- **F03** Session-Widerruf: Deaktivierung/Austritt/Löschen/Passwortwechsel müssen in Redis- UND DB-Fallback-Sessionpfaden wirken; Widerruf dauerhaft speichern. Abnahme: Widerruf wirkt auch bei Redis-Ausfall.
+- **F11** Approval-Resolution: approver_id/Ablauf/Gruppe/Atomarität prüfen, Entscheider getrennt speichern, Approval an Aktion+Argumente+Revision binden.
+- **F15** Workflow-HTTP: aufgelöste IPv4/6-Ziele gegen Privatnetz prüfen, Verbindung an geprüfte Auflösung binden, Redirects prüfen.
+- **F20** prestart überschreibt gezielte Rechte-Entzüge (0100) mit pauschalem GRANT DELETE → Tabellenschutz nur migrieren; keine Rechteanhebung beim Start.
+- **F21** test_migrations.sh: MIGRATION_DATABASE_URL überschreiben + Zielidentität vor DDL prüfen (sonst Gefahr für echte DB).
+- **F23** Tenant-Backup-API triggert datenbankweiten Restore → Gesamtrestore als globale Betriebsoperation mit separater Berechtigung.
+- **F30** Admin-Standardpasswort bei unkonfiguriertem Start → verpflichtendes Secret oder sicherer Einmal-Generierung.
+
+### Welle S2 — Ausführung verbinden (Worker, Jobs, Contracts, Migrationen)
+- **F06** Worker registriert keine der 44 Plugin-Event-Handler (BasePlugin.register_event_handlers ist leer) → API und Worker dieselbe idempotente Registrierung; Abnahme über echten Outbox-Durchgriff (Kontakt anlegen → Worker → Suchindex).
+- **F07** Hintergrundjobs verlieren Mandantenkontext/Transaktionen → Mandant+Auftraggeber im Job-Payload Pflicht; Kontext vor erstem SQL; fachliche Änderung+Audit+Outbox gemeinsam committen.
+- **F08** External-Agent-API: require_permission an Cookie-Auth gebunden (Bearer nie erreicht) + get_db() ist kein Contextmanager (TypeError) → gemeinsamer geprüfter Auth-Kontext für Cookie+Token; Session-Factory statt get_db.
+- **F09** CRM-/MCP-Tools senden nicht anerkannte interne Header → Delegationsmechanismus (delegation_token.py) einbinden; UI und Agent gleiche Rechte-Antwort.
+- **F12** Workflow approve/reject: approval["id"] auf ORM-Objekt (TypeError) + falsche resolve-Signatur → an zentralen Vertrag anpassen, wartende Freigabe auflösen statt Selbst-Genehmigung.
+- **F13** Workflow-Engine: acquire_lock ohne Aufrufer, Idempotenz unvollständig, Resume ungesperrt → Engine als verbindlichen Zustandsübergang; Abnahme: Worker-Neustart + parallele Resume → keine Doppel-Mails.
+- **F14** enforce_data_policy lässt Strings ungefiltert + läuft nur vor der Schleife mit db=None → strukturierte Filterung vor Serialisierung; JEDE LLM-Anfrage (inkl. Tool-Antworten) durch Policy; nicht ladbare Policy = Versand-Stop.
+- **F16** Plugin-Lifecycle: prestart reaktiviert absichtlich deaktivierte Plugins; Aktivierungsfehler lassen DB-Zustand aktiv → gewünschten Zustand von Installation/Mandantenfreigabe/Laufzeitgesundheit trennen; Abnahme: Deaktivierung überlebt Neustart.
+- **F17** 6 Produktionsstellen rufen ContractRegistry.get() auf (existiert nicht; nur get_contract) → Aufrufer fixen; Abnahme über reale Einstiegspunkte (Miniapp-Tools, proaktive Hinweise, Report-Jobs).
+- **F18** Drei Schema-Verfahren (Alembic/Plugin-SQL/sync_plugin_schema) mit Sync-Verlust bei Unique/Partial-Indizes → einen Migrationsbesitzer pro Objekt; Startup-Sync als lesender Driftbericht.
+- **F19** alembic/env.py lädt nur app.models (46/129 Tabellen; Sortierung scheitert) → deterministische vollständige Modelldiscovery.
+- **F31** Provider-Registry vs. Reindex-Listen divergieren → Plugin-Beiträge als gemeinsame Quelle; Abnahme: neuer Provider wird vollständig indiziert.
+- **F37** SMTP-Env-Namen (SMTP_USER vs smtp_username u.a.) → Compose/Config/Doku angleichen; Abnahme: Reset-/Alarm-Mail authentifiziert.
+- **F40** Plugin-Migrationen nur Dateiname-Tracking → Hashes speichern und prüfen; Sollzustand vorhandener Tabellen (Spalten/FKs/Policies) vergleichen.
+- **F41** Agenten-Stundenlimit zählt ab jetzt() statt letzte Stunde → timedelta(hours=1); Kontingent atomar reservieren.
+
+### Welle S3 — Fachliche Integrität (Daten- und UI-Korrektheit)
+- **F25** CSV-Import: Rollback vernichtet frühere Zeilen, Zähler behalten Erfolge, RLS-Kontext weg → Savepoints pro Zeile, Original-Zeilennummern; Zähler = Persistenz.
+- **F26** DMS-Dedup vermischft Identität (fremder Datensatz statt eigener Upload) → Content-Storage vs. Fachobjekt trennen; jeder Upload eigene Identität/Rechte.
+- **F27** Kalender: SQL-Filter wirft Serien weg bevor Wiederholungen berechnet werden; end_at-Dauer; Mehrtagesüberlappung → Serie nach Laufzeit selektieren, Wiederholungen im Fenster erzeugen.
+- **F28** Import/Export ohne Fachrechte (import_export:write ≠ contacts:write; Export ohne Feldrechte) → Fachrechte UND Importrecht; Feldfilter vor Dateierzeugung.
+- **F32** Suche: entity_types=[] = alle (soll 0), Filter nach Top-N, Offset unwirksam, before_search zu spät → None/[] unterscheiden; Filter vor Limit; Hook vor Parametern.
+- **F33** Workspace-Wechsel invalidiert fachliche Querykeys nicht → Workspace in Query-Identität oder kontrolliert verwerfen.
+- **F34** Mandantenwechsel: alte Daten bis Refetch sichtbar → kontrollierter Kontextwechsel (Abbrechen, Caches leeren, Header synchronisieren).
+- **F38** pluginStore-Fehler → Dauerspinner (loaded bleibt false) → Fehler/Leer/Erfolg getrennt rendern, Retry anbieten.
+- **F39** Office-Edit-Session verweist auf /preview (PDF-only) + Callback-Route existiert nicht → funktionsfähigen Ablauf anbinden oder Feature als nicht-betriebsbereit kennzeichnen.
+
+### Welle S4 — Betriebsfreigabe (inkl. korrigierter Phase R)
+- **F22** Backup im Container nicht betriebsfähig (pg_dump fehlt, Pfade nicht persistiert, Kontext-/User-Bugs) → dokumentierter Ablauf mit Programmen, Rechten, persistiertem Ziel.
+- **F24** /health/ready liefert 200 bei not_ready; Worker-Check meldet up ohne Worker → korrekte HTTP-Codes (503), Heartbeat-Alter statt Queue-Länge.
+- **F29** CI ohne Lockfiles/Testdienste/tatsächliches Artefakt → reproduzierbare Pipeline gegen eigenes Image.
+- **F36** Komponenten-Map-Generator nicht verbindlich im Build → Check an npm-Build/Dockerfile/CI hängen.
+- **F04** Suche: autocomplete/similar ohne Objekt-/Feldrechte; Snippet/Titel unfiltert zur LLM → ein Schutzpfad für ALLE Suchvarianten vor Snippet- und LLM-Übergabe.
+- **F35** PWA abgeschaltet, aber Offline-Banner verspricht Schreibspeicherung → PWA wiederherstellen ODER Banner an Realität anpassen.
+- Phase-R-Korrektur (siehe unten, bereits eingearbeitet).
+
+**Abnahmeszenarien quer über alle Wellen (Astra-Vorschlag, verbindlich):**
+1. Kontaktanlage → Audit/Outbox → separater Worker → Suchindex → erlaubte KI-Abfrage (F06, F07, F17, F04)
+2. Mailentwurf → Freigabe → einmaliger Versand → nachvollziehbares Ergebnis (F11, F12, F13)
+
+**Reihenfolge-Logik:** S1 zuerst (jede nicht autorisierte Aktion verboten), S2 parallel startbar nach S1-P0s, S3/S4 danach. Nach S1+S2 verifizierter Welle: Aufwand neu schätzen (Astra-Hinweis: die 9-14 Tage aus Phase R sind keine Schätzung für 41 Findings).
+
+## Phase R — Betriebssicherheit & 95%-Produktionsreife (geplant, user-abgestimmt 2026-09-16 — läuft in S4 auf; korrigiert 2026-09-17 nach Astra-Kritik)
+
+**Ziel:** Von „Produktion läuft stabil" zu „Produktion verlässlich": stille Ausfälle werden automatisch erkannt und alarmiert (Minuten statt Wochen), die Test-Suite wird zum vertrauenswürdigen Regressionsschutz, Schema-Drift wird automatisch erkannt, Kernprozesse werden nach jedem Deploy regressionsgetestet, Backups sind nachweislich wiederherstellbar.
+
+**Warum diese Phase (Evidenz aus realen Incidents):**
+- KI-Chat war 4 Wochen still down — ai_assistant migration_failed seit 2026-08-21, entdeckt am 2026-09-16 nur durch Zufall (#389)
+- External-API war durch CSRF-Middleware für externe Systeme unbrauchbar (fix b91ee5b)
+- Outbox: 158 failed Events wochenlang unbemerkt (#380)
+- Suite-Isolation und alembic-check-Blockade verhindern verlässliche Regressionsschutz-Gates
+
+**95%-Definition (korrigiert 2026-09-17 nach Astra-Kritik):** Die fünf Kriterien sind kein mathematischer Reifegrad, sondern **konkrete Freigabekriterien**. Dokumentiert wird: erfüllte Kriterien, verbleibende Risiken und bekannte Grenzen (Battle-Testing im Echtbetrieb). „95 %" = Zustand, in dem jeder Ausfall laut statt still wird; die restlichen ~5 % sind Echtbetriebs-Edge-Cases, die nur echte Nutzung findet.
+
+**Astra-Kritik an Phase R (8 Punkte, 2026-09-17) — eingearbeitet:**
+1. ARQ-Heartbeat überwacht sich nicht selbst → zusätzlich externe Überwachung außerhalb der ARQ/Redis-Ausfallkette (z.B. Cron auf Host oder externer Uptime-Check gegen /health/ready).
+2. „Installiert aber inaktiv"-Alarm trifft absichtliche Deaktivierung → **Sollzustand** (DB desired state) mit tatsächlicher Betriebsbereitschaft vergleichen; nur Abweichung alarmiert.
+3. Leere Queue ≠ laufender Worker → Worker-Heartbeat-ALTER und Verarbeitungsnachweis messen, nicht Queue-Länge.
+4. Komplette Suite grün reicht nicht (Mocks/Admin-Tests können Rechtefehler verdecken) → zusätzlich echte API-/Worker-Prozesse mit tatsächlichen Laufzeitrollen prüfen.
+5. Ein FK-Fix + Migrationshash genügt nicht → vollständige Modelldiscovery (F19) und eindeutige Schema-Verantwortung (F18) sind Voraussetzung; R3 hängt an S2.
+6. E2E-Normalfälle prüfen Rechteentzug/Neustart nicht → Mehrmandanten-, Rollen-, Fehler- und Wiederaufnahme-Szenarien ergänzen.
+7. Monatlicher Restorejob beweist keine sichere Zielwahl → isoliertes Ziel und tatsächliche DB-+Datei-Wiederherstellung nach Containerersatz nachweisen.
+8. „95 % Produktionsreife" ist keine messbare Zahl → konkrete Freigabekriterien + verbleibende Risiken dokumentieren (siehe oben).
+
+**Aufwandskorrektur (Astra):** Die 9-14 Tage gelten NICHT für die Behebung aller 41 Audit-Findings (Phase S). Neue Schätzung nach Abschluss von S1+S2.
+
+### R1 — Stille-Ausfälle-Wächter + Alerting (2-3 Tage) — PRIORITY 1, größter Risikoreduktor
+- ARQ-Heartbeat-Job (alle 5 Min) prüft: (a) /api/v1/plugins — installiert aber nicht active → ALARM (exakt der #389-Fall), (b) /health/ready — DB/Redis/Storage/Worker, (c) Outbox-DLQ — failed > 0 (#380-Klasse), (d) Worker-Queue-Länge
+- Alarm-Kanal: E-Mail über bestehende Mail-Infra (SMTP) an Admins; Alarm-Zustand zusätzlich als rote Badge im Admin-UI (System-Dashboard)
+- Abnahme live: Plugin absichtlich deaktivieren → Alarm muss nachweislich auslösen (Chaos-Test)
+- Bestand, auf dem aufgebaut wird (kein Neubau): /health/ready (docs/monitoring.md), ARQ-Worker (app/core/worker.py), Mail-Plugin (SMTP), System-Dashboard-Routen
+
+### R2 — Test-Suite verlässlich machen (2-3 Tage)
+- Suite-Isolation fixen: Combo-Runs quaken mit „relation users does not exist" (Solo grün) — conftest.py-DB-Setup deterministisch machen
+- Vitest-Worker-OOM fixen (Worker-/Fork-Konfiguration)
+- Abnahme: `python -m pytest` kompletter Lauf grün + `npx vitest run` kompletter Lauf grün — erst DANACH gilt die Suite als verbindliches DoD-Gate
+
+### R3 — Schema-Integrität automatisieren (1-2 Tage)
+- entity_attachments-FK fixen → `alembic check` läuft als Schema-Drift-Gate
+- Migration-Runner: Hash-Check ergänzen — geänderte getrackte Migration = Alarm statt stiller Skip (verhindert die #389-Bugklasse systemisch)
+- scripts/schema_drift_check.py + scripts/check_migration_hashes.py in scripts/ci_pipeline.sh integrieren
+
+### R4 — E2E-Kernprozess-Regression (2-3 Tage)
+- Playwright-Suite über Kern-Flows: Login, Kontakte-CRUD, Mail senden/lesen, DMS upload/download, Kalender-Termin, KI-Chat-Antwort, Workflow-Ausführung, Gäste einladen
+- Automatischer Run nach jedem Full-Deploy (fast-deploy.sh-Erweiterung)
+- Bestand: Playwright-Setup existiert (frontend/e2e/, Login-E2E bewiesen funktioniert)
+
+### R5 — Backup-/Restore-Nachweis (1-2 Tage)
+- scripts/restore_drill.sh monatlich per ARQ-Job/Cron ausführen + Ergebnis alarmieren
+- RTO/RPO messen und dokumentieren (scripts/backup.py, scripts/restore.py, restore_test.sh existieren)
+
+### R6 — Ops-Runbook & Alarm-Kette final (1 Tag)
+- Eskalationskette: Wer wird wie alarmiert (E-Mail/Handy), wer reagiert
+- docs/incident-response-runbook.md um die realen Ausfallklassen ergänzen (Plugin-inactive, DLQ-Vollauf, Migration-Crash, CSRF/Auth-Layer, Worker-Stillstand) — jede mit Schritt-für-Schritt-Fix aus dem echten Incident
+
+**Aufwand gesamt: ~9-14 Arbeitstage.** R1 zuerst (unabhängig startbar), R2 parallel, R3 nach R2, R4 nach R1, R5/R6 unabhängig. Kann mit Phase O/P verzahnt werden — aber R1-R3 vor neuen Features.
+
+**Definition of Done Phase R:** Alle 5 Abnahmekriterien live gemessen und grün + ein dokumentierter Chaos-Test (absichtlicher Ausfall → Alarm in < 30 Min). Pro Task ein Forgejo-Issue mit Milestone „Phase R — Betriebssicherung" (AGENTS.md §9).
+
+## UI-Backlog — Backend-Module ohne UI (laufend seit 2026-09-08, Source of Truth: PROGRESS.md-Tabelle)
+
+**Kontext:** Frontend-Backend-Gegenüberstellung (2026-09-01) ergab 16 Backend-Module ohne UI (~64 Ops). User-Entscheidung: Module einzeln mit UI ausstatten, priorisiert nach Business-Nutzen. Jedes Modul folgt derselben Verifikationskette: Vitest → tsc → Production-Build → Deploy → Live-API-Check → Forgejo-Issue → PROGRESS.md-Update.
+
+**Status 2026-09-16: 16/16 erledigt — UI-BACKLOG KOMPLETT.**
+- Erledigt: 1 Approvals, 2 Delegations, 3 API-Tokens, 4 Tenants, 5 Marketplace, 6 Permission-Templates, 7 Skills, 8 Agent-Memory, 9 Outbox, 10 Policies, 11 Graph-RAG, 12 Companies, 13 Public-Share, 14 Guests, 15 External-Agent, 16 Ownership-Transfer (Commits + Issues #369, #372-#388 in PROGRESS.md-Tabelle)
+- Alle 16 Backend-Module haben jetzt UI. Bei neuen Backend-Modulen ohne UI: analog verfahren.
+
+**Architektur-Regel (seit Phase Q):** Plugin-Module (wie Marketplace, Skills, Agent-Memory) werden AUSSCHLIESSLICH via Plugin-Manifest registriert (page_routes + menu_items + Komponenten-Map-Generator) — routes/index.tsx und Sidebar.tsx bleiben unangetastet. Core-Module (wie Delegations, API-Tokens, Tenants, Permission-Templates) laufen als statische Core-Routen + Settings-Nav.
+
+**Muster:** Jedes Modul = api/<modul>.ts (TanStack-Hooks) + pages/<Modul>.tsx (Karten/Dialoge/Permission-Gating) + i18n de/en + Vitest-Tests + Registrierung. Referenz-Implementierungen: Approvals (Core) und Marketplace (Plugin/Phase Q).

 # LeoPlatform — Fortschritts-Tracking
 
-> **Letztes Update:** 2026-08-21
-> **Status:** Phase A-K done (261/261 Tasks), 25 Plugins aktiv, Alembic 0136, 2174 Tests
+## Externer Architektur-Audit — 13 Backend-Fixes verifiziert & umgesetzt (2026-09-13, Commit 4a25ac1, [#370](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/370)) ✅
+
+**Ausgangslage:** Externes KI-Audit (leocrm-full.zip, Stand 86cea5d) meldete 17 Findings. Verifikation gegen den echten Code: **alle 17 BESTÄTIGT** (inkl. exakt der 12 gemeldeten fehlenden Permission-Keys — per AST-Scan 1:1 reproduziert). 13 Backend-/Lifecycle-Punkte sofort gefixt; die 4 Frontend-Plugin-Architektur-Punkte sind als **Phase Q** in die Roadmap eingeplant (Begründung dort).
+
+**Fixes (alle mit Live-Verifikation, `tests/test_audit_architecture_fixes.py` 17/17):**
+
+| # | Finding | Fix | Verifikation |
+|---|---|---|---|
+| P1 | `GET /workspaces` lieferte `modules: []` → Workspace-Editor überschrieb Konfig | `list_workspaces()` lädt Module+User-Counts gebündelt (2 Queries statt N+1) | test_f1: modules mit is_visible-Flags 1:1 |
+| P1 | `/plugins/active-manifests` ignorierte Tenant-Deaktivierung (UI zeigte 403-Menüs) | Registry/Service/Route tragen `tenant_id` durch, filtern `tenant_plugin_activation.is_active=false` | test_f2: Plugin im Manifest ohne Filter, gefiltert mit Tenant-Eintrag |
+| P1 | `uninstall()` umging PluginService-Cleanup (stale Permissions/Entity-Models) | `uninstall_plugin()` ruft `deactivate_plugin()` VOR `registry.uninstall()` | test_f3: Quellcode-Verifikation + Lifecycle-Verhalten |
+| P1 | Contract-Lazy-Loading kannte DB-Aktivstatus nicht (Restart-Edge-Case) | Startup markiert `active=False`-Plugins (`mark_db_inactive`), Guard in `get_contract()`, Re-Activate cleart | test_f4: fail-closed + reopen |
+| P1/P2 | `register_field_definitions()` ohne Unregister, nicht im Runtime-Lifecycle | `unregister_field_definitions()` + Aktivierung/Deaktivierung registrieren/entfernen Field-Defs | test_f5: voller Lifecycle über PluginService |
+| P1/P2 | 39 Contact-Felddefinitionen lagen im Core (`CORE_FIELD_DEFINITIONS`) | Verschoben ins ContactsPlugin-Manifest (`field_definitions=`); Core behält nur users-Felder; `sensitive_data.py` nutzt jetzt die Registry-Gesamtsicht | test_f10: Core ohne contacts-Module, Plugin mit 39 Defs, Sensitivities erhalten |
+| P1 | 12 verwendete Permission-Keys nicht registriert | 9 in CORE_PERMISSIONS (automation:admin, bank-accounts:*, delegations:*, policies:*, templates:*), 2 im permissions-Plugin (permissions:read/admin), 1 im forgejo-Reporter (system:read) | AST-Re-Scan: 146 Keys, **0 fehlend**; test_f9 |
+| P2 | `contact_folder` als Core-Entity | Ins ContactsPlugin verschoben; `register_entity_model(..., plugin_name=...)` befüllt jetzt ENTITY_PLUGIN_OWNERS (war tot) | test_f15: `get_entity_read_permission('contact_folder') == 'contacts:read'` via Owner |
+| P2 | Entity-Permission-Fallback `contacts:read` | Fail-closed Sentinel `__unmapped__:read` (nicht grantbar → 403); unbekannte Entities werden vorher via 422 abgelehnt | test_f15 |
+| P2 | Forgejo-Error-Reporter `is_core=True` trotz „test/staging only" | `is_core=False` (deaktivierbar) | test_f11 |
+| P1/P2 | Core-FK `entity_attachments.files` vs. „DMS = Plugin" Widerspruch | **ADR-020:** DMS als Plattform-Core-Plugin deklariert (`is_core=True`) — FK-Richtung ist damit legitim, Registry erzwingt Nicht-Deaktivierbarkeit | test_f12 |
+| P2 | Core-Worker importierte Contact für Trash-Cleanup | `cleanup_contacts_trash` ins Contacts-Plugin ausgelagert (jobs.py, `get_job_modules()`-Discovery wie knowledge), Cron 04:15 | test_f13: kein `app.models.contact`-Import im Worker + Job registriert |
+| P1/P2 | DSGVO-Export doppelt (Legacy-Route kannte Contacts direkt) | `GET /dsgvo-export` delegiert an `_dsar_collect_user_data` (autoritativer DSAR-Collector, Plugin-Contracts) | test_f14: Delegation, kein Contact-Import |
+| P2 | False-green Tests (`or True`, irreführender Name, veraltete >100-Routes-Assertion) | 3 Assertions durch echte Prüfungen ersetzt; Test umbenannt (`_simulated`); Route-Count-Assertion auf Plugin-Architektur umgestellt (vorher schon auf HEAD rot — pre-existing) | Suite grün |
+
+**Nicht als Code-Fix, sondern als Phase Q geplant** (Roadmap „Phase Q“, user-pending): statische Plugin-Routen + Settings-Routen im zentralen Router (Doppel-Architektur), STATIC_COMPONENT_MAP, widgetRegistry — benötigt Build-Time-Discovery-Konzept.
+
+**Beweis Suite-Isolation (nicht durch Fixes verursacht):** test_m4_system_miniapps solo 7/7 grün (mit UND ohne Fixes), test_n4_scope_declarations solo 18/18 grün — Combo-Failures sind das bekannte „relation users does not exist“-Problem.
+
+**Regressionen:** test_contacts_lifecycle 8/8, test_custom_field_definitions, test_contacts_entity_registry 3/3, test_contacts_model_ownership, test_workspace_scopes 18/18, test_rbac_comprehensive, test_plugin_lifecycle_service, test_einvoice_generator — alles grün. Cross-Plugin-Checker: 497 Dateien, 0 verbotene Imports. compileall sauber. Ruff auf 7-Error-Baseline.
+
+**Deployiert & live bewiesen (Commits 4a25ac1 + 1b80090, 2x Full Deploy SUCCESS, Health healthy, Worker up):**
+- GET /workspaces: Standard-Workspace liefert modules=24 (vorher []) — Editor-Overwrite-Bug behoben
+- GET /plugins/active-manifests: 26 Manifeste
+- GET /roles/permissions: 141 Keys, 12/12 neue Keys sichtbar (erste Deploy-Runde nur 11/12 — system:read fehlte, weil der ursprüngliche Patch die permissions-Liste versehentlich in PluginRouteDef-kwargs platziert hatte; in 1b80090 korrekt auf Manifest-Ebene, Test f9 prüft jetzt echte Manifeste statt manueller Registrierung — Live-Check ist DoD-Pflicht)
+- field_definitions: contacts=39 (Plugin), users=4 (Core) — Ownership-Verschiebung live bestätigt
+
+## Phase Q — Frontend-Plugin-Architektur vollendet (2026-09-13) ✅ — PHASE Q KOMPLETT
+
+**Ausgangslage:** Die 4 Frontend-Findings des externen Audits (Doppel-Architektur
+Routen/Settings, STATIC_COMPONENT_MAP, widgetRegistry) wurden als Phase Q geplant
+und jetzt vollständig umgesetzt. Ein Plugin meldet ab sofort Backend, Manifest
+UND React-Komponenten über sein Manifest — keine zentrale Frontend-Datei muss
+mehr angefasst werden.
+
+**Q3+Q4 (Commit 895f85d) — Build-Time-Discovery statt Zentral-Listen:**
+- `scripts/generate_component_map.py`: scannt alle builtin-Manifeste +
+  system_miniapps.py, generiert `frontend/src/generated/pluginComponents.generated.ts`
+  (37 Komponenten). Fail-Hard bei Ghost-Komponenten (bewiesen: exit 1), erkennt
+  default- vs. named-exports, deterministisch, `--check`-Modus für CI.
+- PluginLoader.tsx: STATIC_COMPONENT_MAP (26 Einträge) GELÖSCHT → generierte Map.
+- MiniAppHost.tsx: widgetRegistry (11 Einträge) GELÖSCHT → generierte Map (löst Q4 mit).
+- Contacts-Manifest: DedupMergePage-Pfad-Alias auf echte Datei korrigiert.
+
+**Q1+Q2 (Commit b666fe5) — Manifeste = einzige Routen-Quelle:**
+- routes/index.tsx: 14 statische AppShell-Plugin-Routen + 9 statische
+  Settings-Routen + 20 tote Lazy-Imports entfernt. Nur noch Core-Routen + die
+  StartLayout-Hub-Bäume (/agents, /automation, /logs, /help — verschachtelte
+  Sub-Navigation) bleiben statisch (bewusste Entscheidung: Layout-Routen mit
+  Sub-Navigation werden von flachen Manifest-Einträgen nicht abgebildet).
+- PluginRouteRenderer: neue `variant`-Prop — 'pages' (absolute Pfade, AppShell-
+  Catch-all) vs. 'settings' (bare Sub-Segmente, Descendant-Matching im
+  /settings-Subtree). Getrennte Entry-Listen verhindern Pfad-Kollisionen.
+- Manifeste ergänzt: Calendar +/calendar/kanban, Tags +/tags (+ Menü-Item),
+  Automation: /workflows auf workflows:read (Parität zur ersetzten statischen
+  Route), tote flache /agents-+/automation-Einträge entfernt.
+
+**Verifikation (jeder Schritt live gemessen):**
+- tsc --noEmit exit 0 (nach Q3 und nach Q1/Q2) · production build exit 0 (2×)
+- Ghost-Fail-Hard: Generator exit 1 mit Fehlermeldung bei eingepflanzter Ghost-Komponente
+- Vitest: Dashboard + MiniAppWindow 17/17, pluginStore 18/18, kombiniert 35/35
+- Backend-Regressionen: Route-Order, M5-MiniApps, N4-Scope, N3-Filtering 49/49
+- compileall sauber · Cross-Plugin-Checker 497/0 · ruff clean
+- Full Deploy SUCCESS · Health healthy · Live-Manifest-Checks: /calendar/kanban,
+  /tags, workflows:read, keine toten Einträge — alle OK · SPA-Routen 200
+
+**Nächster Schritt (Roadmap):** Re-Audit durch den externen Prüfer — alle 17
+Audit-Findings sind behoben (13 Backend + 4 Frontend). Danach Phase O UI-Overhaul,
+Phase P Notizen-App oder UI-Backlog-Module 2-16.
+
+
+## Weitermachen (2026-09-15, Übergabe — für das nächste Modell/jede KI)
+
+**Produktion läuft stabil** (HEAD b91ee5b = origin/main, 0 ungepushte Commits, Health healthy, Alembic 0144, RLS 113 Tabellen, Worker up). Alle Forgejo-Issues bis #389 geschlossen. Outbox sauber: 158 Events published (Webhook-Fix #380).
+
+**2026-09-13 bis 16 abgeschlossen:** (1) Externer Architektur-Audit verifiziert — alle 17 Findings bestätigt, 13 Backend-Fixes (Commit 4a25ac1, #370). (2) PHASE Q KOMPLETT — Frontend-Plugin-Architektur: generierte Komponenten-Map (scripts/generate_component_map.py, jetzt 43 Eintraege, Fail-Hard bei Ghosts) ersetzt STATIC_COMPONENT_MAP + widgetRegistry; Plugin-Routen/Settings nur noch aus Manifesten via PluginRouteRenderer (variant pages/settings). (3) Drei Produktions-Bugfixes 2026-09-14 (siehe Bugfix-Tabelle unten): Webhook-JSONB-Containment (#380), Zustands-Selector-Spinner-Hang (#381), Consumer-Registry-qualname. (4) ZWEI weitere Produktions-Bugfixes 2026-09-16 (Bugfix-Tabelle): ai_assistant-Reaktivierung (#389 — KI-Chat war seit 0137 down) + CSRF-Bearer-Skip (External-API fuer Integrationen). (5) **UI-BACKLOG 16/16 KOMPLETT** — alle 16 Backend-Module haben jetzt UI (Commits + Issues #369, #372-#388, siehe Tabelle): Module 11-13 an einem Tag (2026-09-15), Module 14-16 am 2026-09-16 (Guests #386, External-Agent #387 inkl. 2 Backend-Fixes, Ownership-Transfer #388).
+
+**OFFENE THREADS (alles Weitere hängt hier, nichts geht verloren):**
+1. **Re-Audit ausstehend:** Externer Prüfer prueft leocrm-reaudit.zip (Stand b58c96f, liegt beim User). Bei neuen Findings: erst die fixen. Hinweis: ZIP enthaelt NICHT die UI-Module 2-16 — bei Bedarf frischen ZIP erstellen (git archive HEAD).
+2. **Traefik no-cache-Header fuer index.html** (User-Angebot offen, prevents stale JS-Chunks nach Deploys). HINWEIS: Der "Dashboard loads forever"-Incident wurde 2026-09-14 aufgeklaert — es war der Zustands-Selector-Bug (#381), kein Caching-Problem. Der no-cache-Header bleibt trotzdem sinnvoll gegen stale Chunks nach Deploys.
+3. **Server-Entlastung** (User-Thema offen): Cron gegen alte Browser-Prozesse (Incident: 3 Zombie-Chromium, 500+ h CPU) und/oder VPS-Upgrade-Diskussion (22 Container auf 7,6 GB).
+4. **Phase O UI-Overhaul:** offen 1.2 Kontakte-Drag-Drop in Ordner, 1.3 MoveDialog.
+5. **Phase P Notizen-App** (P1-P5, user-abgestimmt, Roadmap-Details stehen).
+6. **Vorbestands-Findings (nicht blockierend):** entity_attachments-FK blockiert alembic check; Suite-Isolation (Combo-Runs "relation users does not exist", Solo gruen); Vitest-Worker-OOM.
+7. **Marketplace ist leer:** Keine Listings in der DB (API 200, listings=0). Demo-Listings koennen via Admin-API (MarketplaceListingCreate, marketplace:admin) angelegt werden — User fragen.
+
+**Offene Roadmap-Phasen (user-abgestimmt, startklar):**
+- **Phase S** — Astra-Sanierung (S1-S4, bestätigt 2026-09-17). **NÄCHSTE PHASE.** Externaudit Astra: 41 Findings (2 P0, 29 P1, 10 P2), 10 stichprobenartig intern verifiziert — alle korrekt. Volltext: [docs/audits/astra-audit-2026-09-17.md](docs/audits/astra-audit-2026-09-17.md). Wellen: S1 Sicherheitsgrenzen [#396](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/396) (**F01 ✓ Commit f2a7206: KI-Tool-Guard an allen Ausführungspfaden, Allowlist+required_permission fail-closed, 18/18 Tests; F02 ✓ Commit 824686c: globale Identität (email/passwort/mehrmandanten-is_active) gegen Mandantenverwaltung geschützt, 13/13 Tests; beide deployed+live-verifiziert; offen: F03, F05, F10, F11, F15, F20, F21, F23, F30**), S2 Ausführung verbinden [#397](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/397) (F06-F09, F12-F19, F31, F37, F40, F41), S3 Fachliche Integrität [#398](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/398) (F25-F28, F32-F35, F38, F39), S4 Betriebsfreigabe [#399](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/399) (F04, F22, F24, F29, F36 + korrigierte Phase R). Milestone 16. Abnahmen quer: Kontaktanlage→Outbox→Worker→Suchindex→KI-Abfrage; Mailentwurf→Freigabe→einmaliger Versand. Neue Aufwandsschätzung nach S1+S2.
+- **Phase R** — Betriebssicherheit & 95%-Produktionsreife (R1-R6, user-abgestimmt 2026-09-16). Läuft in Phase S Welle 4 auf; korrigiert 2026-09-17 nach Astra-Kritik (8 Punkte in Roadmap eingearbeitet). R1 Alerting gegen stille Ausfälle [#390](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/390) (PRIORITY 1 — Evidenz: KI-Chat 4 Wochen still down #389), R2 Suite verlässlich [#391](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/391), R3 Schema-Integrität [#392](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/392), R4 E2E-Kernflows [#393](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/393), R5 Backup-Restore-Drill [#394](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/394), R6 Ops-Runbook [#395](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/395). Milestone 15. 5 messbare Abnahmekriterien = die 95%-Definition (Details + DoD: Roadmap Phase R).
+- **Phase M** — MiniApp-Plattform & Dashboard-Builder (M1-M6). **M1 ✓** (Universal-Registry, `/api/v1/miniapps`), **M2 ✓** (persönliche Dashboards: Tabelle, CRUD, Seed, RLS), **M3 ✓** (Dashboard-Builder: Edit-Modus, Drag&Drop, Palette, Tabs), **M4 ✓** (System-Rückbau, Core = reiner Host), **M5 ✓** (Plugin-MiniApps), **M6 ✓ erledigt — PHASE M KOMPLETT** (Windows-Host + AI-Agenten-Tool send_miniapp — siehe Phase-M6-Section).
+- **Phase N** — Workspace-Scopes (N1-N4). **N1 ✓** (Scope-Registry via Contract), **N2 ✓** (Dynamischer Scope-Editor), **N3 ✓** (Backend-Filterung contacts/dms/mail/calendar + Frontend-Defaults), **N4 ✓ erledigt — PHASE N KOMPLETT** (7 weitere Module: Tasks nur-meine, Kommunikation-Räume, Wiki-Kategorien-Subtree, Reports-Vorlagen, Agents, Tags, Search-Entity-Types + Navigation Startseite/Menü-Reihenfolge + Dashboard-Schnittstelle — siehe Phase-N4-Section). **Nächster Schritt:** Phase O UI-Overhaul (offen: 1.2 Kontakte-Drag-Drop in Ordner, 1.3 MoveDialog) oder Phase P Notizen-App (P1-P5).
+- **Phase O** — UI-Overhaul (umbenannt von Doppel-L, Bug-Verifikation steht im Roadmap-Eintrag: 5/7 Bugs bereits erledigt, offen: 1.2 Kontakte-Drag-Drop in Ordner, 1.3 MoveDialog)
+
+**Vorbestands-Findings (nicht blockierend, dokumentiert):**
+1. `entity_attachments.dms_file_id → files` (Core-FK auf DMS-Tabelle) blockiert `alembic check`
+2. Suite-Isolation: kombinierte Test-Runs quicken mit "relation users does not exist" (Solo-Runs grün)
+3. AppShell vitest worker OOM bei Solo/Combo-Runs
+
+**Modul-Bauplan (bewaehrtes Muster, Module 14-16 direkt anwendbar):** Backend lesen (Routes/Schemas/Permissions) → `api/<modul>.ts` (TanStack-Hooks) oder bestehenden Client erweitern → `pages/<Modul>.tsx` → Registrierung (Plugin: manifest plugin.py page_routes+menu_items + generate_component_map.py + ICON_MAP-Icon; Core: routes/index.tsx + Settings.tsx; oeffentlich: statische Route ausserhalb ProtectedRoute) → i18n de/en (Python-Patch-Skript, JSON-Roundtrip pruefen) → Vitest → tsc → Build → Deploy (frontend-only wenn kein plugin.py; full bei plugin.py) → Live-Verifikation (API curl + echter-Login Playwright DOM-Check) → Forgejo-Issue (Label 5=task, danach schliessen) → PROGRESS.md + Roadmap-Zeile.
+
+**Session-Lektionen fuer Tests/Implementation (2026-09-15, wiederkehrende Stolperfallen):**
+- Vitest: Mutation-Mocks mit `vi.hoisted()` definieren (Top-Level const = ReferenceError durch Hoisting)
+- TanStack Query v5 ruft `mutationFn(variable, context)` — Assertion auf `mock.calls[0][0]`, nicht `toHaveBeenCalledWith(...)`
+- Query-Ergebnisse asynchron: `await screen.findByTestId(...)` statt synchronem getByTestId
+- `window.confirm`: Direkt-Zuweisung im beforeEach (`window.confirm = () => true`), spyOn nur in-Test
+- Hook-Mocks (`useXxx: () => (...)`) sind robuster als queryFn-Mocks — synchron, kein isLoading-Handling
+- text_editor verschluckt gelegentlich JSX-Kommentar-Schliessungen (`*/` ohne `}`): vor tsc mit `grep '{/*'` pruefen
+- Frontend-Catch: der Client-Interceptor wirft `ApiError` mit `.status` auf Top-Level — NICHT `err.response.status` lesen
+- i18n: Block ggf. bereits vorhanden (ungenutzte Alt-Keys) — nur fehlende Keys mergen, nicht ueberschreiben
+- Oeffentliche Seiten (ohne Login): statische Route analog `/guest/*`, NIEMALS in die AppShell/ProtectedRoute
+
+**Wichtig:** AGENTS.md-Regeln zuerst lesen (§0.0 Sub-Agents nur für einfache Jobs, §0.2 auf bestehendem Code aufbauen, §10 'PROGRESS.md als Source of Truth').

+|---|---|---|---|
+| Plugin ai_assistant seit Alembic 0137 (2026-08-21) migration_failed/inactive — KI-Chat und /api/v1/ai/* in Produktion down (403 plugin_inactive); Migration 0003 exec ALTER TABLE ai_chat_sessions crashte bei jedem Container-Start (Tabelle von 0137 gedroppt) | [#389](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/389) | Migrationen 0001-0003 von Referenzen auf gedroppte ai_chat-Tabellen befreit (0003: nur ai_chat_folders behalten; 0001: Ghost-CREATEs entfernt; 0002: attachments+ALTER entfernt).

+## W4c — Custom-Fields-Routen in ContactsPlugin migriert (2026-08-28) ✅
+
+**Verify-first:** `app/routes/custom_fields.py` war 100% Contact-spezifisch (importiert Contact, nutzt contacts:read/write, Route /{contact_id}/custom-fields) — lag aber als scheinbar generischer Core-Service (Kritikpunkt 14).
+
+**Fix (c6decf5):** Die komplette Logik (2 Endpoints GET/PATCH, `_collect_custom_field_definitions`, `_merge_definitions_with_values`, `CustomFieldUpdateRequest`) wandert in `app/plugins/builtins/contacts/routes.py` (gleicher Router-Prefix /api/v1/contacts, bereits via manifest.routes gemounted). `app/routes/custom_fields.py` gelöscht, main.py bereinigt. Der generische `custom_field_definitions.py`-Endpoint bleibt im Core.
+
+**Verifikation:** tests/test_custom_fields.py **11/11 passed** (Funktionserhalt) · create_app OK · ruff grün · Full Deploy SUCCESS · Health healthy
+
+## Phase L1-L3 — Dokumente-Generator Backend+Editor (2026-08-29) ✅
+
+**Scope:** Briefpapier (letterheads) + Druckvorlagen (print_templates) + Assets (document_assets) + Block-Registry + Contract-Beiträge + Drag&Drop-Editor + globaler Dokument-Dialog. Erweiterung des report_generator-Plugins (kein Neubau).
+
+**Umgesetzt:**
+- Backend: `documents.py` (13 Endpoints), `document_blocks.py` (Registry: text/image/shape/table/spacer/divider/placeholder/pagebreak + Modul-Beiträge via `document_blocks()`-Contract), `document_renderer.py` (Blocks→HTML→PDF, WeasyPrint data:-URI-only SSRF-Policy, Briefpapier-@page-Frame mit running header/footer)
+- Contract-Beitrag contacts: `document_placeholders(entity_type)`, `document_data(db, tenant_id, entity_id, entity_type)` (#359-Muster wie importexport_entities)
+- Migration: Plugin-SQL 0003 (idempotent) + Alembic 0143 (Dual-Path-Konvergenz, RLS fail-closed nach 0084-Muster)
+- Frontend: `api/documents.ts` + `DocumentSettings`-Page (Settings→Dokumente, eigener Menüpunkt via settings_pages) + `BlockEditor` (@dnd-kit: Palette/Canvas/Config-Panel/Live-Preview-iframe) + `LetterheadEditor` + `PrintTemplateEditor` + `DocumentGenerationDialog` (global für Module, integriert in ContactDetailPage)
+- i18n de/en vollständig
+
+**Verifiziert:**
+- ✅ tests/test_documents_generator.py: 32/32 (CRUD, Tenant-Isolation, RBAC 403, Block-Validierung 422, Preview, Render-PDF `%PDF`, Assets, Contract-Unit)
+- ✅ Regression: test_report_generator.py + test_plugin_route_order.py 9/9
+- ✅ tsc --noEmit Exit 0; Production-Build OK (2.79s)
+- ✅ Alembic-Fresh-DB: 0001→0143 komplett, letterheads/print_templates/document_assets mit RLS+FORCE+crm_api-Policy bewiesen (Scratch-DB wieder gedroppt)
+- ✅ ruff check clean; check_migration_hashes 93/93 OK
+- ⚠️ Bekannt: Router-Reihenfolge im Manifest — documents-Router muss VOR routes stehen (/{report_id}-Catch-all)
+
+**Offen (Folgepakete):**
+- L4: KI-Steuerung („Erstelle Rechnungsvorlage") via agent_loop
+- L5: E-Rechnung XRechnung/ZUGFeRD (benötigt Verkaufs-Modul)
+- Weitere Module können Blöcke/Platzhalter beisteuern (Contract-Muster dokumentiert in plugin-development-guide.md)
+
+## Phase L4-L5 — KI-Vorschlag + XRechnung-Format-Layer (2026-08-29) ✅
+
+**User-Klärung:** Verkaufsmodul kommt später — aber das XRechnung-FORMAT ist jetzt implementiert (reiner Format-Layer, kein Rechnungs-CRUD).
+
+**Umgesetzt:**
+- L5 Format-Layer: `einvoice.py` — EN16931/XRechnung CII-XML-Generator (ElementTree, XML-Escaping gratis), Pflichtfeld-Validierung mit BT/BG-Codes (BT-1/2/3/5, BT-10, BT-27, BT-31/32, BG-25, BT-126/146), Decimal-kommerzielles Rounding, Header-Tax-Breakdown pro VAT-Satz, Profile en16931|xrechnung (Guideline urn:xoev-de:kosit:standard:xrechnung_3.0)
+- Endpoints: `/einvoice/render` (inline → XML), `/einvoice/validate` (422 mit Fehlliste), `/einvoice/render-for` (Contract-Resolver `einvoice_data()` — Andockpunkt Verkaufsmodul, ohne Beitrag 404 no_data_source)
+- L4 KI-Steuerung: `/documents/suggest` — natürliche Sprache → Block-Komposition via zentralem llm_complete (gpt-4o-mini, Cost-Tracking, Tenant-Budget), Registry-Sanitizing (ungültige KI-Blöcke gefiltert, IDs serverseitig), Code-Fence-Stripping, 502 ai_unavailable/invalid_ai_response
+- Frontend: KI-Vorschlag-Panel im PrintTemplateEditor (Sparkles, Prompt-Textarea, Vorschläge werden an Blöcke angehängt), i18n de/en
+
+**Verifiziert:**
+- ✅ TDD: Rot 25 failed → ✅ Grün **25/25** (tests/test_einvoice_generator.py: Validierung 6 Unit, XML-Struktur 5 Unit inkl. Escaping/Profil/Summen, Contract-Resolution 2 mit Mock-Registry, API 6: 200-XML/422-BT-Codes/403/404, Suggest 6: Mock-LLM/Filter/Fence/502/403)
+- ✅ tsc exit 0 (useMutation-Typisierung SuggestResult,Error,SuggestInput), Production-Build BUILD_EXIT=0
+- ✅ ruff clean
+
+**Offen:** Verkaufsmodul dockt später via `einvoice_data()` an — Contract + Doku (plugin-development-guide.md) fertig.
+
+
+## Phase M — MiniApp-Plattform & Dashboard-Builder (2026-08-29 geplant, user-abgestimmt)
+
+**User-Vision:** Universelle MiniApps (Chat + Dashboard + Windows + AI-Agenten), Dashboard-Builder mit Edit-Modus/Drag&Drop/Resize/Tabs/pro-Widget-Settings, System-Dashboard-Teile zurück in Plugins (Core = reiner Host), Permission-Integration fail-closed.
+
+**Status:** done — M1–M6 alle erledigt (siehe Sections unten). Phase-Gate: alle Tasks implementiert, getestet (TDD), deployed und auf Produktion verifiziert (live curl-Beweise je Section).
+
+**Live-Bestand analysiert (2026-08-29):** miniapp_registry (kommunikation, 92 Z.), MiniAppContribution (LÜCKE: kein permission-Feld), FrontendDashboardWidget (LÜCKE: kein settings_schema), MiniAppBlock.tsx (Chat-Host fertig), DashboardGrid + 4 Widgets, Dashboard.tsx (170 Z.) mit hardcodierten StatCards/ActivityFeed/System-Metrics (Rückbau-Bestand für M4), @dnd-kit vorhanden.
+
+## Phase M1 — Universal-MiniApp-Registry (2026-08-30) ✅
+
+**Umgesetzt:**
+- `app/plugins/miniapp_registry.py` (154 Z.): Registry in den Plugin-Layer gehoben (Plattform-Konzept). MiniAppDef erweitert um `permission` (fail-closed, leer = jeder), `settings_schema`, `col_span`/`row_span`, `hosts` (chat/dashboard/window), `component`, `order`, `builtin`.
+- Kompatibilitäts-Brücke: `kommunikation/miniapp_registry.py` re-exportiert die Universal-Registry — alle Bestands-Importer (kommunikation contracts, automation routes, tests) unverändert lauffähig.
+- Lifecycle: `BasePlugin.on_activate` registriert Manifest-Beiträge automatisch (miniapps + dashboard_widgets-Alias mit component/spans/permission — ein Contribution-Typ, #359-Philosophie); `on_deactivate` entfernt per `unregister_plugin` nur die eigenen Apps.
+- Manifest-Schema: `MiniAppContribution` + `FrontendDashboardWidget` um M1-Felder erweitert (settings_schema, hosts etc.).
+- API: `GET /api/v1/miniapps` (Server-seitig permission-gefiltert, ?host=), `GET /api/v1/miniapps/{app_id}` (403 fail-closed / 404).
+
+**Verifiziert (2026-08-30):**
+- TDD: Rot 16 errors/failed → ✅ Grün **16/16** (tests/test_miniapp_registry.py: Registry-Unit 6, Bridge-Import 1, Manifest-Registrierung+Lifecycle 3, API 6 inkl. Viewer-Filter-Beweis + Host-Filter + 403/404)
+- ✅ Regression: test_contracts.py 23/23, plugin_lifecycle + route_order 4/4, create_app OK
+- ✅ ruff clean (M1-Dateien); 2 Ruff-Funde in automation/knowledge = per Stash bewiesener Vorbestand
+- ✅ Doku: api-documentation.md (2 Endpoints), plugin-development-guide.md (MiniApp-Beitrag-Muster)
+
+**Offen in Phase M:** — (Phase M abgeschlossen).
+
+## UI-Backlog: Frontend-Backend-Gap (2026-09-08 laufend)
+
+**Kontext:** Frontend-Backend-Gegenüberstellung (2026-09-01) ergab 16 Backend-Module ohne UI (~64 Ops) bei 76-84% Business-UI-Coverage. User-Entscheidung: Module einzeln mit UI ausstatten, priorisiert nach Business-Nutzen.

+
+## Phase N4 — Restliche Module (2026-09-01) ✅ — PHASE N KOMPLETT
+
+**Spec:** [#368](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/368) | **Roadmap:** Phase N, N4 (letzter Task) | **Milestone:** Phase N — Workspace-Scopes (#14)
+
+**Umgesetzt:**
+- **Scope-Deklarationen (7 Plugins):** tasks only_mine-Toggle („nur meine"), kommunikation conversation_ids (Räume), wiki category_ids (Subtree — NEUE contracts.py, wiki hatte zuvor keinen Contract), report_generator template_ids (Vorlagen), automation agent_ids (module_key agents — page route ohne Menüeintrag), tags tag_ids (Root-Array), unified_search entity_types DYNAMISCH aus Provider-Registry (13 Entity-Types, Live-Set + deterministischer Klassen-Fallback).
+- **Core-Beiträge (Aggregator):** navigation default_route (Startseite pro Workspace, Optionen aus CORE_PERMISSIONS + bekannten Frontend-Routen) + dashboard widget_app_ids (begrenzt das Widget-TYP-Angebot — workspace_widgets-Boundary; persönliches Layout bleibt Phase M).
+- **Backend-Filter (additive UND, kein Umbau):** GET /tasks (assigned_to OR created_by), GET /comm/conversations (Subset), GET /wiki/articles + /categories (expand_folder_scope-Subtree), GET /reports/print-templates (Subset), GET /agents (Subset), GET /tags (Subset), GET+POST /search (apply_entity_type_scope: requested ∧ scope), GET /miniapps?host=dashboard (widget_app_ids begrenzt NUR Dashboard-Angebot, chat/window unberührt).
+- **Frontend-Navigation:** WorkspaceSwitcher navigiert nach default_route beim Wechsel (Validierung: muss mit / beginnen); Sidebar sortiert nach workspace menu_order als Admin-Default (persönliche savedOrder bleibt Override); workspaceStore moduleMenuOrder()-Helper.
+
+**Verifiziert (2026-09-01):**
+- TDD: Deklarationen **18/18** (rot: 18 failed → Implementation → grün), Filter **11/11** (rot: 8 failed + 1 error → grün; inkl. Dashboard-Boundary: scoped {w1} vs. unscoped Superset, chat unberührt)
+- ✅ Frontend: Vitest Switcher-Navigation 2/2, Store 18/18 (moduleMenuOrder +2), tsc clean, Build OK
+- ✅ Kombi-Regression (N1+N3+N4-Dateien): 64 passed / 4 failed — alle 4 per Solo-Lauf als Suite-Isolation bewiesen (N1 solo 18/18, N3-Test solo grün — bekannter Vorbestand, unterschiedliche Plugin-Fixtures in einem Prozess)
+- ✅ Cross-Plugin-Checker: 0 Verstöße; Ruff: 7 Fehler = exakt Vorbestand (Stash-Beweis: clean HEAD identisch 7)
+
+**Phase N Gesamtbilanz:** Workspace-Scopes komplett — Registry via Contract (N1), dynamischer Editor (N2), Backend-Filterung für alle 11 Module (N3: contacts/dms/mail/calendar + N4: tasks/communication/wiki/reports/agents/tags/search) + Navigation (Startseite, Menü-Reihenfolge) + Dashboard-Schnittstelle (widget_app_ids). Security-Invariante durchgehend: Scope = reine UND-Einschränkung, Exemptions nur System-Admin + configure_modules-Inhaber (Editor-Deadlock). Issues #365-#368 alle geschlossen.
+
+## Phase N3 — Erste vier Module integrieren (2026-09-01) ✅
+
+**Spec:** [#367](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/367) | **Roadmap:** Phase N, N3 | **Milestone:** Phase N — Workspace-Scopes (#14)
+
+**Umgesetzt:**
+- **Core-Resolver** `resolve_workspace_scope()` (workspace_scope_service.py): X-Workspace-ID → Workspace aktiv/Tenant → User-Zuweisung → Modul-config; leere Dimensionswerte fallen weg. Exemptions: System-Admins + `workspaces:configure_modules`-Inhaber — löst den Editor-Deadlock (N2-Scope-Editor lädt Wertoptionen über dieselben Endpoints).
+- **FastAPI-Dependency** `require_workspace_scope(module_key)` (deps.py) — Header-Parsing gekapselt, einzeilige Nutzung pro Route.
+- **Ordner-Subtree** `expand_folder_scope()`: self + descendants (zyklensicher) für ContactFolder + DMS Folder — Ordner-Scopes gelten inkl. Unterordnern. `scope_uuid_set()`: fail-closed (garbage UUIDs → leere Menge).
+- **Listen-Filter (additive UND-Einschränkung, kein Umbau):** contacts (folder_ids-Subtree + contact_types auf GET /contacts; List-Cache bei aktivem Scope deaktiviert — Cross-Workspace-Leak-Gefahr beseitigt), dms (folder_ids-Subtree + file_types auf GET /files, Baum-Reduktion auf GET /folders; semantische Typ-Matcher pdf/image/spreadsheet/word/other), mail (account_ids auf GET /mails, /threads, /accounts-Picker), calendar (calendar_ids auf GET /calendar/entries + /calendars-Picker).
+- **Frontend-Defaults:** `getModuleConfig(moduleKey)` im workspaceStore; ContactsList wendet `default_saved_view_id` beim Mount an (admin-definierte Standard-Ansicht), Calendar setzt `default_view` (day/week/month/range) bei Workspace-Wechsel.
+
+**Verifiziert (2026-09-01):**
+- TDD: Rot (7 ImportError + 14 Fixture-Errors) → ✅ Grün **21/21** (Resolver 7, Contacts 5 mit Cache-Bypass-Beweis + scharfem AND-Beweis (Beta=Person im Ordner-Scope fällt raus), DMS 3, Mail 3, Calendar 3 inkl. Admin-Bypass)
+- ✅ Regression: N1 + N2 + Workspaces + test_mail **81 passed**
+- ✅ Cross-Plugin-Checker: 0 Verstöße; Ruff: nur per Stash bewiesener Vorbestand (N806/UP017)
+- ✅ Frontend: tsc clean, Vitest (workspaceStore 16/16, CalendarPage, ContactsList) grün, Production-Build OK
+
+**Offen in Phase N:** N4 restliche Module (Tasks „nur meine", Kommunikation-Räume, Wiki-Kategorien, Reports-Vorlagen, Automation-Agenten, Tags, Search-Provider, Navigation-Defaults) + Dashboard-Schnittstelle (workspace_widgets begrenzt Widget-TYP-Angebot).
+
+## Phase N2 — Dynamischer Scope-Editor (2026-09-01) ✅
+
+**Spec:** [#366](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/366) | **Roadmap:** Phase N, N2 | **Milestone:** Phase N — Workspace-Scopes (#14)
+
+**Umgesetzt:**
+- **WorkspaceScopeEditor.tsx** (neu): generisches Filter-UI aus /scope-definitions — multiselect (statische Options ODER value_source-Fetch), select (mit 'Keine Einschränkung'-Placeholder), toggle. WidgetSettingsForm-Philosophie (M3): die Komponente kennt keine spezifischen Module, Plugins deklarieren via Contracts.
+- **resolveScopeItems** (api/hooks/workspaces.ts): Wertequellen-Auflösung für alle N1-Formate — items-Wrapper (contact-folders), Root-Listen (mail/accounts, calendars, saved-views), DMS-Ordner-Baum (children-Flattening). Nie-crashend: defekte Responses → leere Liste.
+- **Hooks:** useWorkspaceScopeDefinitions (queryKey workspace-scope-definitions) + useScopeValues (endpoint-spezifisch, staleTime 60s).
+- **WorkspaceManager:** JSON-Textarea-Editor ENTFERNT — dynamischer Scope-Editor inline pro sichtbarem Modul; Speicherung unverändert über POST /{id}/modules in workspace_modules.config.
+- **i18n:** workspaces.scopeEditor.* 5 Keys (de/en) — hint (Security-Invariante im UI), noRestriction, noDimensions, noValues, loadError.
+
+**Verifiziert (2026-09-01):**
+- TDD: Rot 4 failed → ✅ Grün **21/21** (WorkspaceScopeEditor 17: resolveScopeItems-Unit 4, Rendering 7, onChange 6; WorkspaceManager-Integration 4: Textarea weg + Scope-Fields da, Config-Roundtrip checked, Save-Payload config korrekt, No-Dimensions-Hinweis nach Toggle)
+- ✅ npx tsc --noEmit: clean (0 Errors)
+- ✅ Production-Build: OK (vite build, nur Chunk-Size-Warnung Vorbestand)
+- ✅ Frontend-only-Deploy + Bundle live verifiziert
+
+**Offen in Phase N:** N3 Backend-Listen-Filterung via X-Workspace-ID (additive UND-Einschränkung: contacts Ordner/Typen/View, dms Ordner/Typen, mail Postfächer, calendar Kalender/View), N4 restliche Module.
+
+## Phase N1 — Scope-Registry via Contract (2026-08-31) ✅
+
+**Spec:** [#365](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/365) | **Roadmap:** Phase N, N1 | **Milestone:** Phase N — Workspace-Scopes (#14)
+
+**Umgesetzt:**
+- **Contract-Hook `workspace_scopes()`** (document_placeholders-Muster, #359-Philosophie): Plugins deklarieren Scope-Dimensionen ihres Moduls inkl. Wertequellen; der generische Editor bleibt modul-agnostisch.
+- **Deklarationen (4 N3-Module):** contacts (folder_ids via /api/v1/contact-folders, contact_types Firmen/Personen, default_saved_view_id via /api/v1/saved-views?entity_type=contact), dms (folder_ids via /api/v1/dms/folders, file_types PDF/Bilder/Tabellen/Dokumente/Sonstige), mail (account_ids via /api/v1/mail/accounts), calendar (calendar_ids via /api/v1/calendars, default_view Tag/Woche/Monat/Zeitraum — Frontend-Ansichten live abgeglichen).
+- **Pydantic fail-closed** (app/schemas/workspace.py): ScopeOption, ScopeValueSource (nur interne /api/v1/-Pfade — SSRF-sicher per Konstruktion; Validator), WorkspaceScopeDimension (multiselect/select ohne options UND value_source → ValidationError), WorkspaceModuleScopes (module_key + min. 1 Dimension).
+- **Aggregator** (app/services/workspace_scope_service.py): iteriert discovered Plugins, lazy-loadet Contracts, ARCH-014-safe (deaktivierte bleiben weg), Crash-sicher pro Plugin, ungültige Deklarationen verworfen (Warning-Log).
+- **Endpoint** `GET /api/v1/workspaces/scope-definitions` (workspaces:configure_modules — Admin-Kontext) — VOR /{workspace_id} registriert (Route-Order-Falle, test_plugin_route_order-Klasse).
+
+**Verifiziert (2026-08-31):**
+- TDD: Rot (ImportError) → ✅ Grün **18/18** (tests/test_workspace_scopes.py: Pydantic-Unit 4, Contract-Deklarationen 8, Aggregator fail-closed 1, HTTP-Endpoint 2 (Admin bekommt alle 4 Module, Viewer-403), Route-Order 1, Value-Endpoint-Existenz via OpenAPI 1 (431 Pfade, app.routes enthält nur _IncludedRouter-Wrapper — isinstance-Scan versagt, OpenAPI kanonisch), /context-config-Regression 1)
+- ✅ Regression: test_workspaces.py **17/17**
+- ✅ Cross-Plugin-Checker: 0 Verstöße (495 Dateien)
+- ✅ Ruff clean (alle 8 geänderten Dateien; UP037-Quote-Fix)
+
+**Offen in Phase N:** N2 Dynamischer Scope-Editor (WorkspaceManager rendert Filter-UI aus /scope-definitions, Speicherung in workspace_modules.config), N3 Listen-Filterung via X-Workspace-ID (additive UND-Einschränkung), N4 restliche Module.
+
+## Phase M6 — Weitere Hosts (2026-08-30) ✅ — PHASE M KOMPLETT
+
+**Spec:** [#364](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/364) | **Roadmap:** Phase M, M6 (letzter Task)
+
+**Umgesetzt:**
+- **Windows-Host:** `openMiniAppWindow`-Helper + `MiniAppWindowContent` (windowStore, schwebende/verschiebbare Fenster, kompakte Default-Größe 520×480). Öffnen-Buttons: Chat-Block (MiniAppBlock, ExternalLink-Icon) und Dashboard-Widget (DashboardBuilder, auch View-Modus).
+- **AI-Agenten-Host:** Core-Tool `send_miniapp` (app/ai/miniapp_tools.py) — Agent bettet MiniApp als interaktiven Ausgabe-Block (block_type miniapp, approval_request-Präzedenz) in seinen Chat-Raum ein. Permission fail-closed gegen den aufrufenden User pro App (resolve_permissions + check_permission); Registrierung im lifespan-Startup.
+- **agent_loop:** tool_context um agent_name erweitert (Raum-Auflösung "Agent: {name}").
+- **Fix:** MiniAppBlock nutzt jetzt useMiniapps (universelle Registry MIT component-Feld) statt Legacy /comm/miniapps — der Fenster-Button erscheint damit erstmals zuverlässig.
+- **Fix (Vorbestand, live gemessen):** /api/v1/agents/tools rief registry.list_tools() auf (Methode existiert nicht → 500) — auf list_for_api() mit korrektem Feld-Mapping umgestellt + Regressionstest gesichert.
+
+**Verifiziert (2026-08-30):**
+- TDD: Rot 7 failed → ✅ Grün **8/8** (tests/test_m6_miniapp_hosts.py: Tool-Registrierung 1, Handler 5 (unknown/nie-posten/Permission-deny/Block-Posting mit exakter block_data/no-room-degradation), agent_name-Kontext 1, list_for_api-Regression 1)
+- ✅ Backend-Regression: M6 + M5 + Phase-F-Agenten **57/57**
+- ✅ Frontend: Vitest **26/26** (4 neue Window-Tests: MiniAppWindowContent-Rendering + openMiniAppWindow-Store-Integration, Typ/Title); `npx tsc --noEmit` clean; Production-Build OK (2.74s)
+- ✅ Deploy (335762d + 04e9279, Full): Health healthy, Alembic 0144, RLS 113 Tabellen
+- ✅ Produktions-Verifikation (curl): /api/v1/agents/tools listet **send_miniapp live** (18 Tools total, plugin system) — Vorbestands-500 gefixt; neuer Frontend-Bundle live
+
+**Phase M Gesamtbilanz:** MiniApp-Plattform komplett — universelle Registry (M1), persönliche Dashboards mit RLS (M2), Builder mit Drag&Drop/Tabs/Settings (M3), Core als reiner Host (M4), 8 Plugins + 2 System-Apps liefern Widgets (M5), Chat + Dashboard + Fenster + AI-Agenten als Hosts (M6). 17 Apps, 11 renderbar, in Produktion live.
+
+## Phase M5 — Plugin-MiniApps (2026-08-30) ✅
+
+**Spec:** [#363](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/363) | **Roadmap:** Phase M, M5
+
+**Umgesetzt:**
+- 5 Manifest-Beiträge (MiniAppContribution, gleiche Philosophie wie contacts_stats):
+  - dms: `dms_folders` (dms:read, Ordner mit Dateizählern, Settings max_items)
+  - mail: `mail_unread` (mail:read, ungelesene Mails je Ordner, Settings max_items)
+  - wiki: `wiki_recent` (wiki:read, zuletzt aktualisierte Artikel, Settings max_items)
+  - graph_rag: `graph_overview` (graph:read, Beziehungsübersicht, Settings max_items)
+  - automation: `automation_status` (automation:read, aktive/inaktive Automationen, Settings max_items)
+- 5 Frontend-Widgets auf bestehenden API-Clients (keine neuen Backend-Endpoints, §0.2): DmsFoldersWidget (fetchFolders), MailUnreadWidget (fetchAccounts+fetchFolders/unread_count), WikiRecentWidget (fetchWikiArticles), GraphOverviewWidget (fetchGraphRelationships), AutomationStatusWidget (useAutomations). MiniAppHost-Registry +5.
+- **Bug gefunden & gefixt (live gemessen):** automation/plugin.py on_activate re-registrierte Manifest-MiniApps in einem Legacy-Block OHNE component/permission — überschrieb die korrekte M1-Registrierung aus super().on_activate(). Legacy-Block entfernt + Regressionstest gesichert (test_automation_legacy_reregistration_removed).
+- ruff: wiki I001 Import-Sortierung gefixt.
+
+**Verifiziert (2026-08-30):**
+- TDD: Rot 7 failed → ✅ Grün **8/8** (tests/test_m5_plugin_miniapps.py: Manifest-Felder 5, Lifecycle-component-Beweis 1, settings_schema 1, Legacy-Regressionstest 1)
+- ✅ Backend-Regression: M5 + Registry + M4 + M2 **53/53**; nach automation-Fix: M5 + lifecycle + registry **26/26**
+- ✅ Frontend: Vitest **22/22**; `npx tsc --noEmit` clean; Production-Build OK
+- ✅ Deploy (7ed5349 + cd34bab, Full): Health healthy, Alembic 0144, RLS 113 Tabellen
+- ✅ Produktions-Verifikation (curl): /api/v1/miniapps?host=dashboard liefert **17 Apps, 11 renderable** — alle 5 neuen Apps live mit component und Permission (automation_status nach Fix: comp=YES, perm=automation:read)
+
+## Phase M4 — System-Rückbau (2026-08-30) ✅
+
+**Spec:** [#362](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/362) | **Roadmap:** Phase M, M4
+
+**Umgesetzt:**
+- `app/core/system_miniapps.py`: Core-eigene MiniApps — `audit_activity` (Aktivitäten, audit:read, settings_schema max_items 1-50, Standard 10) + `system_metrics` (DB/Redis/Worker/API, settings:read; Endpoint /system/dashboard bleibt require_admin, Widget zeigt ohne Admin-Rechte kompakten Hinweis). Registrierung im lifespan-Startup (main.py), unabhängig von Plugin-Aktivierung.
+- **base.py-Fix (M1-Lücke):** native Manifest-MiniApps reichen jetzt `component` an die Registry durch (vorher nur der dashboard_widgets-Alias — Ursache, warum Chat-Apps kein component hatten).
+- **contacts-Manifest:** `contacts_stats` als native MiniApp (ContactsStatsWidget, contacts:read, settings: show_companies/show_persons) — Nachfolger der StatCards.
+- **Seed-Fix (routes/dashboards.py):** Dashboard-Seed platziert nur renderbare Apps (component vorhanden) — Chat-Interaktions-Apps ohne Frontend-Component bleiben aus Layouts raus (Produktions-Messung M2: 9 Widgets, nur 3 renderbar → jetzt gefiltert).
+- **Frontend-Widgets:** ContactsStatsWidget (Firmen-/Personen-Zähler), AuditActivityWidget (ActivityFeed-Nachfolger, max_items), SystemMetricsWidget (DB/Redis/Worker/API-Karten) — alle mit WidgetComponentProps (settings). MiniAppHost-Registry +3.
+- `Dashboard.tsx` ist reiner Host (26 Z.): keine hardcodierten Inhalte mehr — StatCards/ActivityFeed/SystemMetrics existieren ausschließlich als persönliche MiniApp-Instanzen.
+- i18n: systemMetricsNoAccess (de/en). M2-Seed-Tests auf renderbare Apps umgestellt (neue Seed-Spezifikation).
+
+**Verifiziert (2026-08-30):**
+- TDD: Rot 7 errors → ✅ Grün **7/7** (tests/test_m4_system_miniapps.py: System-App-Definitionen 4, API-Permission-Filter 2, Seed-component-Filter 1)
+- ✅ Backend-Regression: M4 + M2 (angepasst) + MiniApp-Registry **46/46** — base.py-Fix und Seed-Änderung brechen keine Bestandstests
+- ✅ Frontend: Vitest **22/22** (Builder 13, Page-Pure-Host 4 neu geschrieben, i18n 5); `npx tsc --noEmit` clean; Production-Build OK
+- ✅ Deploy (3c496f4, Full): Health healthy, Alembic 0144, RLS 113 Tabellen
+- ✅ Produktions-Verifikation (curl): /api/v1/miniapps?host=dashboard liefert **12 Apps, 6 renderable** (vorher 3) — contacts_stats/audit_activity/system_metrics live mit component; Chat-Apps korrekt comp=NONE
+
+## Phase M3 — Dashboard-Builder-Frontend (2026-08-30) ✅
+
+**Spec:** [#361](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/361) | **Roadmap:** Phase M, M3
+
+**Umgesetzt:**
+- `api/miniapps.ts` + `api/dashboards.ts`: TanStack-Query-Hooks (M2-Backend + M1-Registry, Query-Keys + Invalidation nach documents.ts-Muster); `renderableDashboardApps()` filtert Apps ohne component (6 der 9 Bestands-Apps sind Chat-Interaktions-Apps ohne Frontend-Component).
+- `MiniAppHost.tsx`: ersetzt DashboardWidgetLoader (P2-F17-Erbe) — Lazy-Component-Registry + settings-Props an Widget-Komponenten; Apps ohne Component renderen render_schema-Karte (MiniAppBlock-Präzedenz).
+- `DashboardBuilder.tsx` (605 Z.): View/Edit-Modus-Schalter; @dnd-kit-Sortable-Grid (rectSortingStrategy) mit 12-Spalten-Flow-Repositionierung (identisch zum Server-Seed); Palette (permission-gefiltert via /api/v1/miniapps?host=dashboard, nur renderbare Apps); Resize (col/row ±, geclamped 1-12); Tab-Verwaltung (Add/Remove/Rename, min 1); Dashboard-CRUD + Set-Default; Dirty-Check (Save disabled bei unverändertem Layout); Settings-Modal pro Widget.
+- `WidgetSettingsForm.tsx`: generisches Form aus settings_schema (text/number/boolean/select, MiniAppField-Typ).
+- Bestands-Widgets auf settings-Props umgestellt (RecentContacts nutzt settings.limit, geclamped 1-50; Tasks/Calendar kompatibel optional).
+- `Dashboard.tsx`: Builder als Hauptinhalt (reiner Host-Pattern); StatCards/SystemMetrics/ActivityFeed bleiben sichtbar bis M4-Rückbau (kein Funktionsverlust).
+- Legacy `DashboardGrid.tsx` + `DashboardWidgetLoader.tsx` gelöscht; Geister-Test ersetzt (§10: UI-Änderung → Test-Nachzug).
+- i18n: dashboard.builder.* 22 Keys (de+en).
+
+**Verifiziert (2026-08-30):**
+- ✅ Vitest: DashboardBuilder-Tests **13/13** (Render, Tabs, View/Edit-Schalter, Palette-Add, Save-Flow-Koordinaten-Beweis {col:3,row:0}, Dirty-Disabled, Resize→col_span 3, Tab-Add/Remove, Settings-Modal mit Schema-Feld, Dashboard-Wechsel, Create-Modal, Empty-State) — TDD-äquivalent: 2 anfängliche Test-Bugs (multiple elements) gefixt, dann grün
+- ✅ Page-Regression: dashboard/Dashboard.test.tsx **11/11** (Builder-Mocks ergänzt); i18n-Test grün (de/en)
+- ✅ `npx tsc --noEmit` clean; Production-Build **OK** (2.98s)
+- ⚠️ Sidebar-Test-Run: Worker-OOM (0 Tests ausgeführt) = PROGRESS.md Finding #3 Vorbestand (identisch bei AppShell-Runs vor M3)
+- ✅ Frontend-Deploy (26948fd, ~20s): neuer Bundle live (index-BGuPWW7I.js), Health healthy, Login 200; /api/v1/miniapps?host=dashboard liefert 3 renderbare Apps von 9 (component-Filter greift: 6 Chat-Interaktions-Apps ohne Frontend-Component)
+
+## Phase M2 — Dashboard-Backend (2026-08-30) ✅
+
+**Spec:** [#360](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/360) | **Roadmap:** Phase M, M2
+
+**Umgesetzt:**
+- `app/models/dashboard.py`: `dashboards`-Tabelle (persönlich, saved_views-Präzedenz: user_id NOT NULL CASCADE, TenantMixin, kein OwnedMixin). Layout JSONB, `is_default`, partial unique index (tenant, user, name) WHERE deleted_at IS NULL — soft-deleted Boards geben Namen frei (Verbesserung ggü. saved_views-Wart).
+- `app/schemas/dashboard.py`: DashboardLayout/Tab/Widget (12-Spalten-Grid: col/row ≥ 0, Spans 1-12) → 422 auf invalide Layouts, bevor persistiert wird.
+- `app/routes/dashboards.py` (313 Z.): 6 Endpoints — GET (Liste + lazy Seed), POST (409 dup, erstes = default, ein leerer Start-Tab), GET/{id}, PUT/{id} (Name/Layout, db.refresh gegen MissingGreenlet), DELETE/{id} (Soft-Delete, Default-Promotion), POST/{id}/set-default (exakt ein Default). Owner-only (tenant + user_id Filter, fremde = 404), Audit-Log bei allen Mutationen.
+- Lazy Default-Seed: erste GET-Abrufung erzeugt „Mein Dashboard“ aus MiniApp-Registry (permission-gefiltert via geteiltem `user_permits`, Registry-Order, 12-Spalten-Flow mit Wrap).
+- `user_permits()` in miniapp_registry.py als geteilter Fail-Closed-Filter (miniapps.py behält `_user_permits`-Alias).
+- CORE_PERMISSIONS: `dashboard:read`/`dashboard:write` — **fixt Phantom-Permission** (app/routes/dashboard.py verlangte dashboard:read, nirgends registriert → Nicht-Admins konnten sie nie erhalten).
+- Migration `0144_personal_dashboards.py`: dashboards-Tabelle + RLS im 0090-Muster (**crm_api + crm_worker**) + **konvergenter Fix der 3 Phase-L-Policies** (letterheads/print_templates/document_assets waren `TO crm_api`-only — live auf Produktion gemessen, s. Verifikation). Plugin-SQL 0003 ebenfalls auf beide Rollen korrigiert.
+- Doku: api-documentation.md (neue Core-Section dashboards, 6 Endpoints).
+
+**Verifiziert (2026-08-30):**
+- TDD: Rot 21 failed/1 passed → ✅ Grün **23/23** (tests/test_dashboards_backend.py: Model/Permission-Unit 3, Layout-Validation 5, CRUD 9, Ownership/Isolation 4, RLS-Konvergenz 2)
+- ✅ Live-Messung (psql): Produktion vor Fix — 3 Policies `{crm_api}`-only (letterheads, print_templates, document_assets); lokal nach 0144 — alle 4 Tabellen `{crm_api,crm_worker}`
+- ✅ Regression: rls_coverage + miniapp_registry + dashboard + lifecycle + route_order 37/38 — 1 Failure (test_dashboard cross-tenant, POST /companies 405) = **per Stash bewiesener Vorbestand** (identischer Failure auf clean HEAD); solo 5/5 grün
+- ✅ Regression Welle 2: rbac_comprehensive + arch_block_a **125/125**
+- ✅ ruff clean (alle M2-Dateien inkl. Testdatei); create_app OK (85 Router-Routen)
+- ✅ Deploy (b3e259f, Full-Deploy): Health healthy, Alembic 0144, RLS 113 Tabellen
+- ✅ Produktions-Verifikation (psql + curl, 2026-08-30): alle 4 Policies {crm_api,crm_worker}, 0 fehlende Rollen; GET /api/v1/dashboards liefert Lazy-Seed („Mein Dashboard", default, 1 Tab, 9 Widgets aus Registry)
+
+## Phase N — Workspace-Scopes (2026-08-30 geplant, user-abgestimmt)
+
+**User-Vision:** Workspaces als voll anpassbare Arbeitskontexte — jedes Modul pro Workspace auf Teilmengen einschränkbar (z.B. nur Kontakt-Ordner X+Y, nur DMS-Ordner "Angebote", nur Mail-Postfach vertrieb@, nur Kalender "Vertrieb"). Admin-definiert, für zugewiesene User-Gruppen.
+
+**WICHTIG — Klarstellung Workspace ≠ Dashboard (user-korrigiert):** Zwei getrennte Systeme. Workspace = Admin-Kontext (WAS ist sichtbar/verfügbar, Gruppen-Feature). Dashboard = persönlich (WIE ICH mein Dashboard baue, Phase M). workspace_widgets bleibt Workspace-Eigentum (verfügbare Widget-TYPEN), dashboards-Tabelle (Phase M2) bleibt User-Eigentum (persönliches Layout). Kein Überbau, keine Vermischung.
+
+**Status:** not_started — Phase N (N1-N4) in PLATFORM_ROADMAP.md verankert. 0 Umbau nötig: Speicher (workspace_modules.config JSONB), Transport (X-Workspace-ID-Interceptor), Context-Endpoint und Sidebar-Consumer existieren bereits; N3/N4 = additive Scope-Anwendung in Modul-Listen (kein Refactoring).
+
+**Security-Invariante:** Scope = reine UND-Einschränkung (Workspace-Scope ∧ RLS ∧ ABAC ∧ Permissions). Workspace kann NIE mehr sichtbar machen, nur weniger. Ohne Workspace = kein Filter (rückwärtskompatibel).
+
+## Phase P — Notizen-App (Notion-artig, ersetzt Wiki) (2026-08-30 geplant, user-abgestimmt)
+
+**User-Entscheidung:** Wiki wird komplett ersetzt durch Notion-artige Notizen-/Firmen-Wissen-App. Keine Legacy-App, keine Notion-Datenbanken erstmal — MiniApp-Blöcke stattdessen. Quer-Verweise + vollständige Such-Indexierung Pflicht. Edit-Konzept: Live-Inline-Editing wie Notion (kein Mode-Toggle, Auto-Save), Lese-Modus entsteht über Permissions + optional Page-Lock.
+
+**Status:** not_started — Phase P (P1-P5) in PLATFORM_ROADMAP.md verankert. P1-P3+P5 unabhängig startbar; P4 braucht M1 (MiniApp-Registry).
+
+## W3b — Settings Contribution-Wahrheit (2026-08-28) ✅
+
+**Verify-first (Live-Messung):** 7 Plugins liefern `settings_pages` via Manifest (mail, ai_assistant, ai_proactive, automation, permissions ×3, system_notif) — die hardcoded Items in `Settings.tsx` für mail/ai/notifications waren identische Duplikate.
+
+**Fix (b1a7551):** hardcodedNavItems auf 7 echte Core-Settings reduziert (stammdaten, user-management, system, custom-fields, webhooks, workspaces, backup) — Plugin-Settings kommen ausschließlich via pluginNavItems. Path-Dedup bleibt als Sicherheitsnetz.
+
+**Dashboard-Verify (Kritikpunkt 20a):** Dashboard.tsx lädt Widgets bereits dynamisch via `useDashboardWidgets()` API (Manifest-Contributions von calendar/contacts/tasks) → DashboardWidgetLoader ist nur der Vite-Code-Splitting-Renderer, **keine fachliche Doppelquelle** — Kritikpunkt 20a teilweise widerlegt.
+
+**Verifikation:** Vitest 90/90 (13 Dateien inkl. settings + dialog + permissions) · tsc exit 0 · frontend-only Deploy FE_EXIT=0
+
+## Suite-Isolation (2026-08-28) ✅
+
+**Mechanismus (Live-Messung):** `close_engine()` in der rbac `mail_app`-Fixture disposiert UND setzt alle globalen Engines auf None — 12 ACL-Batch-Failures (`relation "users" does not exist`) in Nachfolger-Suiten.
+
+**Fix (b691dd3):** `reset_engine_for_testing(engine)` nach `close_engine()` im Teardown — conftest-Engine wird als globale Engine wiederhergestellt (Produktions-Bootstrap-Spiegelung).
+
+**Verifikation:** ACL-Batch vorher 12 failed/118 passed → nachher **130 passed** (alle 12 behoben).
+
+**Nur tests/ geändert — kein Production-Deploy nötig.**
+
+## W4a — Import/Export Contribution-Architektur (2026-08-27, SPECS final)
+
+**Spec:** [#359](https://forgejo.media-on.de/Leopoldadmin/leocrm/issues/359) (user-abgestimmt)
+
+**Kernentscheidungen:** Zentraler Dialog (Modal lg/xl) geöffnet per Toolbar-Button in jeder Modulliste, deren Plugin Import/Export anbietet; /import-export-Seite wird zur Übersicht aller Angebote (Variante b). Formate als Plugins (CSV/JSON/XLSX bundled; PDF später separat). Module = Contributors via Contract (`importexport_meta`); Core = Orchestrator + Sicherheits-Policy-Layer (Sensitive-Filter, Tenant-Scoping, Audit unabhängig vom Modul erzwungen). Modul-native Formate (ICS/EML/ZIP) registrieren sich nur anzeigend.
+
+**Abgelöst:** `export_service.py` (78 Z., CSV-only, alter /export-Endpoint) + contact-spezifische Logik in `import_export_service.py` (504 Z.) — der bewiesene Doppel-Weg wird konsolidiert.
+
+### Phase 1 — Backend-Kern ✅ (cd8ef75, deployed 21:14)
+
+- Format-Registry `app/core/importexport_registry.py` (FormatHandler-Protokoll, `available_for()` Schnittmenge)
+- `importexport_formats`-Plugin (csv/json/xlsx), lifecycle-korrekt (on_activate registriert, on_deactivate entfernt)
+- ContactsContract `importexport_entities()` + `ie_*`-Methoden (Columns, Validatoren, Normalizer, Fetch, Persist mit Audit)
+- `import_export_service.py` generische Engine — iteriert über `registry.list_discovered()`, keine hartcodierten Plugin-Namen
+- **Funktionserhalt: 45/45 import_export-Suite passed** (inkl. Fehler-Multiplizität: 2 failed rows → 3 total_errors via ie_required + ie_row_valid-Trennung; Zwischenstand mit 2 Failures live gefangen und korrigiert)
+
+### Phase 2 — Frontend-Dialog ✅ (38df597, deployed 21:34)
+
+- `ImportExportDialog.tsx` (neu): Modal lg/xl, Export-Tab (1 Schritt) + Import-Tab (4 Schritte: Datei → Mapping-Editor → Dry-Run → Ausführung+Report inkl. Background-Job-Polling)
+- 24 `importexport.*`-i18n-Keys (de + en, keine hardcoded Strings)
+- ContactsList: Toolbar-Button (contacts:read-Gate, Upload-Icon, entityType vorgewählt) über pluginToolbarStore
+- **Verifikation: Vitest 12/12** (importExportDialog 6/6 + routePermissions 6/6) · tsc exit 0 · Production-Build exit 0 · 6 contacts/shell-Failures per Stash-Test als Vorbestand bewiesen (identisch auf clean HEAD) · frontend-only Deploy FE_EXIT=0
+
+### Phase 3 — PDF (separat, offen)
+
+PDF als weiteres Format-Plugin — eigener Design-Baustein (Library-Choice, Templates pro Modul).

Begründung des Owners: Er ist der einzige, der je Zugriff auf das Repo hatte (Single-Operator); Git-Historie-Kompromittierung ist ohne Dritte kein aktuelles Risiko. Rest-Risiken akzeptiert: Server-Compromise, Backup-Leaks, künftige Mitwirkende müssten bei Onboarding neu bewertet werden | ✅ Entscheidung dokumentiert; Rotations-Anleitung bleibt in deploy-guide.md für den Fall eines späteren Team-Onboardings oder Verdachtsfalls; E7 CI-Gate überwacht künftig keine Credentials mehr in Dateien (Secrets-Hygiene bleibt) | — |

+| I-B | Cross-Tenant-Suite v2: Vakuum-Tests zu echter RLS-Verifikation — crm_api-Rolle NOBYPASSRLS, RLS auf 117 Tenant-Tabellen + tenant_isolation-Policies im conftest, seed_data commit + Teardown-Cleanup, admin_session ohne externe Transaktion, UUID/String-Normalisierung, discount_* NOT NULL im Raw-INSERT | ✅ 10/10 grün; Regression: v1-Suite 8/8, ruff=0, Cross-Plugin 0 Verstöße, Migration-Hashes OK | 5d8c48a |
+| I-D-1 | ai/sessions ×5: Backend hat KEIN Sessions-CRUD; einziger Nutzer AISidebar renderte nur Platzhalter von 404-Calls gesteuert; Geister-Tests ChatWindow/SessionList importierten nicht existierende Komponenten | ✅ Geister-Tests gelöscht (BUG-099-Muster); AISidebar Chat-Tab zeigt Verweis auf /ai-assistant-Seite; api/ai.ts 253→170 Zeilen tote Exports entfernt; tsc=0, vitest ai 26/26 | 3e5f13f |
+| I-D-2 | policies ×4: policies.ts + policyHooks.ts hatten NULL Importeure im gesamten Frontend (tote Kette seit Erstellung) — Nested-Routen /policies/{type}/{id} existieren nicht | ✅ Beide Dateien gelöscht statt Backend-Shims zu bauen; tsc=0 beweist keine versteckten Abhängigkeiten | 86c96f0 |

+| I-E-1 | Mail-Suite: 35 Timeouts + 1 Failure in 18:29min — Root-Cause: test_delete_folder trigger imap_delete_folder → echter IMAP-Connect zu imap.example.com blockiert und vergiftet Event-Loop für alle Folge-Tests (Kaskade ab 12. Test) | ✅ **46/46 grün in 94.41s**; autouse mock_imap_connections-Fixture im conftest (deterministischer Fake-IMAP-Client via monkeypatch); dabei 2 echte Bugs behoben: create_mail_account setzt jetzt owner_id (403 bei assign_shared_users — Production-Bug), /mail/threads gibt Array statt {items,total} (konsistent mit Geschwister-Routen + fetchThreads-Typing); test_download_attachment auf produktionskonformen relativen storage_path umgestellt (Path-Traversal-Guard hatte korrekt gearbeitet) | c291a6e |
+| I-E-2 | PluginLoader ×5: Tests erwarten 'Failed to load plugin: {name}' + text-red-600 am alert-Container, Loader zeigte deutsche Hardcode-Texte ohne Plugin-Namen | ✅ **6/6 grün**; Fallback auf getesteten Contract umgestellt statt Tests zu biegen; tsc=0 | 9e1d202 |

Mehrkomponenten-Dateien (17 Dateien nachgezogen, ObjectPattern-Deklarationserkennung), Re-Parse-Gate je Datei, 423 neue de.json-Keys (Fallback en→de per fallbackLng). Beweise: tsc --noEmit exit=0, Produktionsbuild OK, Vitest 20F **byte-identisch zur Clean-Tree-Stash-Baseline** (alle Vorbestand); v1-Batch (Import-Slice-Bug) vollständig revertiert, nie committed | 4cb5298 |
+| I-H-Test | Verifikationslauf aller gemeldeten Vorbestand-Failures: pytest BUG-093–098 (cross_tenant/api_audit/commands/auth/rls = 66 passed), test_mail 46 passed, phase_g+spike_i 46 passed — ALLE bereits grün; npm audit live 0 vulnerabilities; dazu echter Render-Loop-Bug in Tasks/Reports/Communication gefunden und behoben (zustand Whole-Store-Destructuring → Selektor-Pattern, wie Dms/Mail es schon richtig machen); 17 Vitest-Failures nachgezogen (Tasks 3-Spalten-Layout, MiniApp async, Router QueryClient, Toast flache API, automation mockResolvedValue); 5 Geister-Tests gelöscht (Komponenten weg seit db4701b); Playwright-Specs aus Vitest exkludiert; dump.rdb-Hygiene (G3). Beweise: 7 Suiten 107/107 grün, tsc=0, Build OK; AppShell-4-Failures bleiben bewusst auf Baseline (Mock-Versuch induziert Worker-Hang — Clean-Tree-Beweis per Stash, Root-Cause-Doku folgt) | 1a24e3e..cfb2bfe |
+| I-G-Rest | God Objects: 35 Python-Dateien >500 Z. — Plan verlangt Hotspot-priorisierte Splits mit eigenem Commit je Datei, NICHT Big-Bang | ✅ **Pilot ABGESCHLOSSEN**: mail/services.py 3087→~170 Z. (**−95%**) — reine Re-Export-Fassade mit __all__, Implementierung komplett in 12 Sub-Modulen (accounts/crypto/drafts_sync/imap_ops/imap_sync/pgp/rules_vacation/sanitize/serializers/smtp_send/text_utils/attachments). Fixes während Extraktion: get_account_password async-Fix, aiosmtplib-Modulattribut für Test-Mocks, conftest-Mock-Pfad auf imap_sync, test_mail SMTP-Mock-Pfade auf smtp_send, Fassaden-Re-Exports ergänzt (MAX_ATTACHMENT_SIZE/_sanitize_filename/imap_create_folder/imap_delete_folder/mail_to_response). Beweise: mail+sig_label_routes **51/51 passed**; alle 13 Sub-Module Import-OK; Symbol-Auflösung MISSING:NONE; ruff clean | a1d5e56, be81fe5, 6702d69, fce17aa, ea6c9e7 |
+| I-G-Rest | God Objects: zweitgrößter Python-Hotspot dms/routes.py (1492 Z., 24 Routen) | ✅ **Split ABGESCHLOSSEN**: routes.py 1492→650 Z. (**−56%**) — neu: common.py (alle Safety-/Storage-Helper + Konstanten, exakte Original-Implementierung), folders_routes.py / sharing_routes.py / search_bulk_routes.py je eigener prefix-loser Router; routes.py behält den File-Lifecycle-Kern physisch (erhält die test_dms_coverage MAX_FILE_SIZE-Patch-Semantik auf Modul-Globals) und dient als Re-Export-Fassade + include_router ×3. Beweise: DMS-Suite **129 Tests = 125 passed + 4 identische Vorbestand-Failures** (Baseline vor dem Split 1:1 reproduziert, 249s→249s); **20/20 Routen** via Router-Introspection (9 Core-APIRoutes + 3 _IncludedRouter mit 4/3/4 Routen) bei unverändertem Prefix /api/v1/dms; ruff clean; plugin.py-Ladepfad (module=…routes, router_attr=router) unangetastet; keine Test-Edits | f445aa6 |
+| I-G-Rest | God Objects: drittgrößter Hotspot kommunikation/services.py (1364 Z., 28 Funktionen) | ✅ **Split ABGESCHLOSSEN**: services.py → Re-Export-Fassade (~70 Z.) + 6 Sub-Module (serializers/conversations/participants/messages/interactions/plugin_rooms) mit azyklischer Schichtung (serializers ← interactions ← conversations ← messages ← plugin_rooms); MAX_TRIGGER_DEPTH nur noch in messages; Fassade exportiert alle 27 Symbole + Konstante (routes.py/contracts.py/test_notification_migration.py unverändert). Beweise: Comm-Suite **132P/1F/6E identisch zur Pre-Split-Baseline** (FAILED/ERROR-Liste byte-identisch), ruff clean (F821/F401/F811/I001), 24/24 Routen intakt, notifications.py-Delegation OK | 5680179 |
+| I-G-Rest | DMS Vorbestand-Failures ×4 (shared_with_me empty/multiple_files, Streaming CHUNK_SIZE ×2) | ✅ **ALLE 4 BEHOBEN**: Suite 125 grün + 4 failed → **129/129 PASSED** (253s). (1) shared_with_me Leerpfad: self-inconsistent (Erfolgspfad pures Array, Leerpfad Envelope {items,total}, Schwester-/search Array) → konsistentes []; Frontend dms.ts Z.196 vertraegt beide Shapes. (2+3) CHUNK_SIZE historischer Kontrakt gerissen: Originaltest importierte CHUNK_SIZE aus routes (727d866), a614ab3 entfernte den Import statt das fehlende Symbol zu liefern → NameError ×2; Fix: oeffentliche Konstante in common.py + Re-Export + restaurierte Importzeile (keine Assertion angefasst). (4) multiple_files: KEIN Codebug — content_hash-Dedup ist bewusstes Produktionsfeature (routes.py Z.145-160); Test lud 3x byteidentischen Inhalt und verletzte docs/test-strategy.md-Konvention (unterschiedlicher Inhalt je Upload); User-freigegebener minimaler Test-Edit (PDF_CONTENT + str(i).encode()), Dedup bleibt vollstaendig aktiv | e025541, 84061fd |
+| G2 | Session-Revocation bei Passwortänderung — Befund differenzierter als Plan annahm: Reset-via-Token (confirm_password_reset) revocierte Sessions bereits korrekt (Redis scan_iter session:*), aber Profil-/Admin-Pfad (users.py PATCH → update_user mit new_password) liess alle anderen Sessions aktiv — Angreifer mit gestohlener Session blieb aktiv | ✅ **120/120 grün** (auth+user_service+rbac_comprehensive in 144s); revoke_user_redis_sessions(user_id)-Helper in auth.py extrahiert (never-raises), von beiden Pfaden genutzt; Postgres sessions-Tabelle unberührt (Audit-Trail by Design) | 0baec27 |
+| G1-a | DSGVO Art. 17 Löschung **nicht funktionsfähig**: POST /dsar/{user_id} queued einen process_dsar-Job der nirgends implementiert war (grep: nur die Route referenziert ihn) — DSAR-Requests verschwanden im Nirvana; Art. 15 Auskunft lieferte nur 3 statt aller versprochenen Kategorien | ✅ **4/4 grün** (test_g1_dsar): _dsar_collect_user_data sammelt profile+contacts+audit_log+notifications (Art. 15/20); _dsar_execute_deletion führt Art. 17 aus — contacts soft-delete (Audit-/Aufbewahrungspflichten respektiert), notifications hard-delete, User anonymisiert + deaktiviert mit FK-Integrität für Audit-Zeilen, dsar_erasure-Audit-Eintrag; process_dsar dispatcht access/deletion/rectification (rectification = manuelle Bearbeitung via Systemnachricht) | f4a5937 |
+| G1-b | dsgvo-export-Endpoint-Docstring versprach Mail-Accounts/Tasks/Calendar/Comm-Messages — geliefert wurden nie welche (Docstring-Fiktion) | ✅ Export auf 8 Kategorien erweitert (2d17746); zusätzlich Frontend-DSGR-UI nachgereicht: 4. ComplianceTab-SubTab 'DSGVO-Anfragen' mit Typ-Wahl Art.15/17/16, Personen-Auswahl (useUsers), direktem GDPR-Export-Download (Blob) und zweistufiger Löschbestätigung; nutzt vorhandene /system-settings/dsar + /dsgvo-export Endpoints; tsc=0, Build OK | 05bc1e2 |

+- ~~Cross-Tenant v1/v2 Doppel-Suiten~~ ✅ Konsolidiert: v1 bleibt als 8-Test-Basis-Suite grün (8/8), v2 ist die echte RLS-Verifikation (10/10) — beide haben unterschiedliche Scopes, keine Duplikate.
+- ~~5 PluginLoader-Test-Failures~~ → I-E (Tests erwarten UI-Text 'Failed to load plugin', Loader zeigt deutsche Texte).
+- ~~BUG-099~~: workstream.py gelöscht, Tests importieren es noch (~4 Failures) → I-E (Tests löschen/umbauen; Modul ist Phase-2-Roadmap). Teilweise erledigt: Geister-Tests ChatWindow/SessionList bereits in I-D-1 gelöscht.

-# LeoCRM UI-Overhaul-Plan (v2)
-
-> **Erstellt:** 2026-08-21
-> **Aktualisiert:** 2026-08-21 — AI Assistent Integration hinzugefügt
-> **Status:** Planung — nicht gestartet
-> **Leitlinie:** Auf bestehendem Code aufbauen, 3-Spalten-Explorer-Layout als Standard, keine parallelen Systeme
-
----
-
-## Standard-Layout (Referenz: ContactsList.tsx)
-
-Alle Explorer-Plugins nutzen das 3-Spalten-Layout aus den UI-Design-Guidelines:
-
-```
-┌─────────────┬──────────────────┬──────────────────────┐
-│   Tree      │   Liste/Ansicht   │   Detail             │
-│  (224px)    │   (flex-1)        │   (flex-1 / 60%)     │
-│ ResizablePanel│  ResizablePanel   │   ResizablePanel     │
-└─────────────┴──────────────────┴──────────────────────┘
-```
-
-- **Toolbar oben:** PluginToolbar mit Filter-Dropdowns, Ansichts-Umschaltern, Aktion-Buttons
-- **Linke Spalte:** ResizablePanel mit Baumansicht (Ordner, Kategorien, Kalender)
-- **Mitte:** Liste, Karten, Kalender-Ansicht — mehrere Ansichten umschaltbar
-- **Rechts:** Detail-Bereich für ausgewähltes Element
-
----
-
-## Phase 1: Echte Bugs fixen (2-3 Tage)
-
-### 1.1 Kontakte — Liste aktualisiert nach Speichern nicht
-- **Datei:** `frontend/src/pages/ContactsList.tsx`
-- **Problem:** Nach dem Speichern eines Kontakts wird die Liste nicht aktualisiert
-- **Ursache:** Wahrscheinlich fehlendes `invalidateQueries` nach Mutation
-- **Fix:** TanStack Query `useCreateContact` mutation muss `queryClient.invalidateQueries({ queryKey: ['contacts'] })` im `onSuccess` haben
-- **Aufwand:** 1 Stunde
-
-### 1.2 Kontakte — Drag-Drop von Kontakten in Ordner nicht möglich
-- **Datei:** `frontend/src/pages/ContactsList.tsx`, `frontend/src/components/contacts/`
-- **Problem:** Drag-Drop von Kontakten in Ordner funktioniert nicht
-- **Fix:** HTML5 Drag-Drop API auf Tree-Nodes implementieren, `onDrop` handler der `updateContact({ folder_id })` aufruft
-- **Aufwand:** 3 Stunden
-
-### 1.3 Kontakte — Verschieben-Dialog funktioniert nicht
-- **Datei:** `frontend/src/components/contacts/MoveDialog.tsx` (oder ähnlich)
-- **Problem:** Ordner-Auswahl im Verschieben-Dialog leer oder broken
-- **Fix:** Ordner-API aufrufen und im Dialog anzeigen, Auswahl speichern
-- **Aufwand:** 2 Stunden
-
-### 1.4 Wiki — Artikel kann nicht gespeichert werden
-- **Datei:** `frontend/src/pages/Wiki.tsx`, `frontend/src/api/knowledge.ts`
-- **Problem:** Speichern-Button funktioniert nicht oder API gibt Fehler zurück
-- **Diagnose:** API-Endpunkt prüfen (`POST /api/v1/wiki/articles` oder `PATCH /api/v1/wiki/articles/:id`), Frontend-Mutation prüfen
-- **Fix:** Je nach Diagnose — API-Fehler oder Frontend-Mutation-Fehler
-- **Aufwand:** 2 Stunden
-
-### 1.5 Kalender — Dialog schließt nicht nach Speichern
-- **Datei:** `frontend/src/pages/Calendar.tsx`, `frontend/src/components/calendar/AppointmentEditForm.tsx`
-- **Problem:** Nach dem Speichern eines Termins schließt sich der Dialog nicht
-- **Fix:** `onSuccess` handler muss `setEditingEvent(null)` oder `setShowDialog(false)` aufrufen
-- **Aufwand:** 30 Minuten
-
-### 1.6 Kommunikation — Chats können nicht angelegt werden
-- **Datei:** `frontend/src/pages/Communication.tsx`
-- **Problem:** "Neuer Chat" Button funktioniert nicht oder API gibt Fehler
-- **Diagnose:** API-Endpunkt prüfen (`POST /api/v1/comm/conversations`), Frontend-Mutation prüfen
-- **Fix:** Je nach Diagnose
-- **Aufwand:** 2 Stunden
-
-### 1.7 Wiki — Doppelt im Menü
-- **Datei:** `frontend/src/routes/index.tsx`, `frontend/src/components/layout/` (Navigation)

----
-
-## Phase 2: AI Assistent in Kommunikation integrieren (2-3 Tage)
-
-### Problem
-Der AI Assistent ist ein paralleles System das die Kommunikation-Plattform dupliziert:
-- **AI Assistant Tabellen:** `ai_conversations`, `ai_messages` (app/models/ai_conversation.py) + `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` (app/plugins/builtins/ai_assistant/models.py) — 5 Tabellen
-- **AI Assistant Frontend:** `AIAssistant.tsx`, `AIAssistantStandalone.tsx`, `SessionList.tsx`, `ChatWindow.tsx` — eigene UI
-- **AI Assistant API:** `/api/v1/ai/sessions`, `/api/v1/ai/sessions/:id/messages`, `/api/v1/ai/sessions/:id/stream` — eigene API
-- **Kommunikation hat schon AI-Chat:** `comm_conversations` mit `conversation_type='ai'`, `streamChat()` aus `@/api/ai`, `categorizeConversation()` mit 'KI Chats' Kategorie, `new-ai-chat` Toolbar-Button
-
-### 2.1 Daten-Migration (Backend)
-- **Migration 0137:** Migriere `ai_chat_sessions` → `comm_conversations` (conversation_type='ai')
-  - `ai_chat_sessions.id` → `comm_conversations.id`
-  - `ai_chat_sessions.title` → `comm_conversations.title`
-  - `ai_chat_sessions.tenant_id` → `comm_conversations.tenant_id`
-  - `ai_chat_sessions.user_id` → `comm_conversations.owner_id`
-  - `ai_chat_sessions.agent_id` → `comm_conversations.metadata.agent_id`
-  - `ai_chat_sessions.created_at` → `comm_conversations.created_at`
-- **Migration 0137:** Migriere `ai_chat_messages` → `comm_messages`
-  - `ai_chat_messages.id` → `comm_messages.id`
-  - `ai_chat_messages.session_id` → `comm_messages.conversation_id`
-  - `ai_chat_messages.role` → `comm_messages.sender_type` ('user' → 'user', 'assistant' → 'ai')
-  - `ai_chat_messages.content` → `comm_messages.content`
-  - `ai_chat_messages.tenant_id` → `comm_messages.tenant_id`
-- **Migration 0137:** Migriere `ai_conversations` → `comm_conversations` (falls Daten vorhanden)
-- **Migration 0137:** Migriere `ai_messages` → `comm_messages` (falls Daten vorhanden)
-- **Migration 0137:** Drop `ai_conversations`, `ai_messages`, `ai_chat_sessions`, `ai_chat_messages`, `ai_chat_attachments` Tabellen
-- **Aufwand:** 1 Tag
-
-### 2.2 Backend — AI Chat API auf Communication umleiten
-- **Datei:** `app/plugins/builtins/ai_assistant/routes.py`
-- **Änderung:** `POST /api/v1/ai/sessions` → erstellt `comm_conversations` mit `conversation_type='ai'` statt `ai_chat_sessions`
-- **Änderung:** `GET /api/v1/ai/sessions/:id/messages` → liest aus `comm_messages` statt `ai_chat_messages`
-- **Änderung:** `POST /api/v1/ai/sessions/:id/stream` → bleibt erhalten (streaming endpoint) aber speichert messages in `comm_messages`
-- **Aufwand:** 4 Stunden
-
-### 2.3 Frontend — AI Assistant Page entfernen
-- **Entfernen:** `frontend/src/pages/AIAssistant.tsx`
-- **Entfernen:** `frontend/src/pages/AIAssistantStandalone.tsx`

-- **Entfernen:** `frontend/src/components/ai/ChatWindow.tsx`
-- **Route anpassen:** `/ai-assistant` → **gelöscht** (kein Redirect nötig)
-- **Route anpassen:** `/ai-assistant-standalone` → **gelöscht** (kein Redirect nötig)
-- **Navigation:** AI Assistent Menüpunkt entfernen, AI Chat bleibt unter Kommunikation
-- **Aufwand:** 2 Stunden
-
-### 2.4 Frontend — Communication AI-Chat verbessern
-- **Datei:** `frontend/src/pages/Communication.tsx`
-- **Änderung:** AI Chat Sessions aus `comm_conversations` laden (statt `ai/sessions` API)
-- **Änderung:** `streamChat()` bleibt erhalten aber Session-ID ist jetzt `comm_conversation_id`
-- **Änderung:** AI Chat Messages aus `comm_messages` laden
-- **Aufwand:** 4 Stunden
-
-### 2.5 Backend — ai_assistant plugin models aufräumen
-- **Entfernen:** `AIChatSession`, `AIChatMessage`, `AIChatAttachment` Models aus `app/plugins/builtins/ai_assistant/models.py`
-- **Entfernen:** `AIConversation`, `AIMessage` Models aus `app/models/ai_conversation.py`
-- **Behalten:** `AIProvider`, `AIModel`, `AIPreset`, `AIChatFolder` Models (für Settings)

-- **Aufwand:** 2 Stunden
-
-### 2.6 Unified Search — AI Chat Provider anpassen
-- **Datei:** `app/plugins/builtins/unified_search/providers/ai_chat_provider.py`
-- **Änderung:** Search auf `comm_messages` (conversation_type='ai') statt `ai_chat_messages`

-### Reihenfolge:
-1. **Phase 1** (Bugs) — zuerst, damit grundlegende Funktionen arbeiten
-2. **Phase 9** (Strukturelle Änderungen) — schnell, wenig Aufwand
-3. **Phase 5** (Kalender) — kleines Update, baut auf Phase 1 auf
-4. **Phase 2** (AI Assistent → Kommunikation) — entfernt paralleles System, baut auf Phase 1.6 auf
-5. **Phase 6** (Tags) — unabhängig, Backend + Frontend
-6. **Phase 4** (Tasks) — großer Umbau, unabhängig
-7. **Phase 3** (Wiki) — größter Umbau (WYSIWYG Editor), baut auf Phase 1 auf
-8. **Phase 7** (Reports) — großer Umbau, unabhängig
-9. **Phase 8** (Kommunikation) — baut auf Phase 2 auf
-
-### Migrationen:
-- **0137:** AI Assistent Tabellen → comm_conversations/comm_messages + Drop alte Tabellen
-- **0138:** Tags: parent_id, applicable_to, icon Spalten
-- **0139:** Reports: folder_id Spalte
-- **0140:** Communication: comm_conversation_folders Tabelle oder folder_id in comm_conversations
-
-### Was ich NICHT tun werde:
-- Keine Massen-Scripts die neue Fehler verursachen
-- Keine Änderungen ohne Verifizierung gegen Produktion
-- Keine neuen Plugins wenn bestehende erweitert werden können
-- Keine neuen Pages wenn bestehende umgebaut werden können
-- Jede Änderung wird mit tsc und API-Test verifiziert
-
-### Was ich brauche:
-- **IMAP-Zugangsdaten:** Für Mail-Postfach-Test (Phase 9.2)

-Based on Rentman's contact model: a single table with type field
-('company' or 'person'). ContactPerson is a 1:N child for
-ansprechpartner (company employees / contact persons).
+The physical home of Contact/ContactPerson moved to the ContactsPlugin:
+    app/plugins.builtins.contacts.models
+
+This module re-exports both classes lazily (PEP 562 ``__getattr__``) so every
+existing import keeps working - ``from app.models.contact import Contact``
+resolves at attribute-access time:
+    - alembic/env.py (``from app.models import *`` -> Base.metadata stays
+      complete; Autogenerate never sees the tables as removed)
+    - Core services (worker.py, jobs.py, address_service.py, ...)
+    - 19 test files and scripts
+
+Why LAZY and not a top-level import: app/models/__init__.py is imported very
+early (app.core.auth imports app.models.session). A top-level plugin import
+here would pull in app.plugins -> registry -> service_container -> cache ->
+app.core.auth while app.core.auth is still initializing -> circular ImportError
+(proven in the Paket 6 red run). With PEP 562 the plugin framework is only
+touched when Contact is actually accessed, long after app.models finished
+initializing - every entry order is cycle-free.
+
+The cross-plugin checker (scripts/check_cross_plugin_imports.py) lists this
+file in EXEMPT_PATHS: the re-export is the deliberate, documented bridge -
+the plugin OWNS the model; the core only mirrors it for import stability.
