# Audit Fix-Plan — LeoCRM Architektur-Audit

**Basis:** `docs/audit-consolidated-errors.md` (153 eindeutige Fehler)
**Datum:** 2026-08-15

---

## Prinzipien

1. **P0 zuerst** — Runtime Crashes müssen sofort behoben werden
2. **Kein neues Architekturmodell** — vorhandene Interfaces nutzen
3. **Deklarierte Plugin→Plugin-Abhängigkeiten sind erlaubt**
4. **Minimal focused changes** — bestehenden Style beibehalten
5. **Jeder Fix wird verifiziert** — Tests laufen, App startet

---

## Phase 1: P0 Runtime Crashes (8 Fixes, ~2h)

### 1.1 hooks.py:83 — unregister() _filters 2-tuple CRASH
**Datei:** `app/core/hooks.py:83`
**Änderung:** `register_filter` speichert 3-tuple `(priority, callback, owner_tag)`, aber `unregister()` unpackt nur 2-tuple. Fix: `unregister()` auf 3-tuple unpacking aktualisieren.
**Verifikation:** `pytest tests/test_hooks.py -v`

### 1.2 trigger_dispatcher.py:127 — AutomationDefinition nicht importiert
**Datei:** `app/core/trigger_dispatcher.py:127`
**Änderung:** `AutomationDefinition` wird in Query verwendet aber nie importiert. Fix: Import hinzufügen (via Contract oder lazy import).
**Verifikation:** `pytest tests/test_trigger_core.py -v`

### 1.3 contacts/plugin.py:88-90 — clear_actions() statt unregister_actions_by_owner()
**Datei:** `app/plugins/builtins/contacts/plugin.py:88-90`
**Änderung:** `clear_actions()` entfernt Hooks ALLER Plugins. Fix: `unregister_actions_by_owner("contacts")` verwenden.
**Verifikation:** `pytest tests/test_contacts_lifecycle.py -v`

### 1.4-1.8 Test P0s — check_permission mocked + hardcoded DB credential
**Dateien:** `tests/test_external_agent_api.py`, `tests/test_graph_rag.py`, `tests/test_agent_memory.py`, `tests/test_marketplace.py`, `tests/test_cross_tenant_standalone.py`
**Änderung:**
- 4 Dateien: `patch("check_permission", return_value=True)` entfernen, echte Permission-Setup verwenden
- 1 Datei: Hardcoded DB credential durch env var ersetzen
**Verifikation:** `pytest tests/test_external_agent_api.py tests/test_graph_rag.py tests/test_agent_memory.py tests/test_marketplace.py tests/test_cross_tenant_standalone.py -v`

## Verifikation nach jeder Phase

1. `python -m pytest -v --tb=short` — alle Tests grün
2. `cd frontend && npx tsc --noEmit` — TypeScript kompiliert
3. `python -c "from app.main import app; print(len(app.routes))"` — App startet
4. `python scripts/check_cross_plugin_imports.py` — 0 Verstöße

## Reihenfolge

1. **Phase 1** — P0 Runtime Crashes (sofort, blockiert alles)
2. **Phase 2** — P1 Funktionale Fehler (nach P0)
3. **Phase 3** — P2 Architekturfehler (nach P1, kann parallel)
4. **Phase 4** — P3 Code Quality (nach P3, kann parallel)
