+"""Restore tenant RLS, transfer ownership, fix roles and grants.
+
+This migration implements Phase 1 of the Sanierungsplan:
+
+1. Transfer ALL table ownership from crm_user (SUPERUSER) to crm_migration (NOSUPERUSER, NOBYPASSRLS)
+2. ALTER ROLE crm_migration NOBYPASSRLS
+3. Enable RLS + FORCE on ALL tenant tables (tables with tenant_id column)
+4. Drop ALL old policies (scoped to {public} or using non-NULLIF patterns)
+5. Create new fail-closed policies scoped to {crm_api, crm_worker}
+6. Revoke excessive grants from crm_runtime, crm_worker, crm_api, crm_auth
+7. Grant proper minimal permissions to crm_auth (identity tables only)
+8. Grant CRUD to crm_api and crm_worker on tenant tables
+9. Revoke alembic_version access from crm_api and crm_worker
+10. Set default privileges for crm_migration owner
+11. Drop crm_runtime legacy role
+12. Create crm_platform_admin role (for one-time infrastructure only)

+# Phase 0 — Frozen Error List (P0/P1)
+
+**Date:** 2026-07-31
+**Baseline commit:** 11d6faa (tag: v-phase0-baseline)
+**Phase 0 commit:** 032a7e8
+
+---
+
+## P0 — Critical Security Issues
+
+### P0-01: All tables owned by SUPERUSER role
+- **Severity:** P0
+- **Files:** All 123 tables in `public` schema
+- **Tables:** ALL
+- **Reproduction:** `SELECT tableowner FROM pg_tables WHERE schemaname='public'` → all `crm_user`
+- **Target:** Owner = `crm_migration` (NOSUPERUSER, NOBYPASSRLS)
+- **Status:** Open — Phase 1
+
+### P0-02: `crm_migration` has BYPASSRLS
+- **Severity:** P0
+- **Files:** DB role `crm_migration`
+- **Reproduction:** `SELECT rolbypassrls FROM pg_roles WHERE rolname='crm_migration'` → `true`
+- **Target:** `ALTER ROLE crm_migration NOBYPASSRLS`
+- **Status:** Open — Phase 1
+
+### P0-03: RLS disabled on ~70+ tenant tables
+- **Severity:** P0
+- **Tables:** contacts, addresses, attachments, ai_*, calendar_*, comm_*, mail_*, workflows, etc.
+- **Reproduction:** `SELECT relname FROM pg_class WHERE relrowsecurity=false AND relforcerowsecurity=true`
+- **Target:** ENABLE ROW LEVEL SECURITY on all tenant tables
+- **Status:** Open — Phase 1
+
+### P0-04: Old RLS policies scoped to `{public}` — potential cross-transaction leak
+- **Severity:** P0
+- **Tables:** ~70+ tables with old `tenant_isolation` policy
+- **Reproduction:** `SELECT policyname, roles FROM pg_policies WHERE roles='{public}'`
+- **Target:** Drop old policies, create new ones scoped to `{crm_api, crm_worker}`
+- **Status:** Open — Phase 1
+
+### P0-05: No separate database connections for auth/api/worker/migration
+- **Severity:** P0
+- **Files:** `app/config.py`, `app/core/db/__init__.py`
+- **Reproduction:** `grep -n 'auth_database_url\|worker_database_url' app/config.py` → not found
+- **Target:** 4 separate engines with separate pools and roles
+- **Status:** Open — Phase 1
+
+### P0-06: Worker uses `crm_api` role instead of `crm_worker`
+- **Severity:** P0
+- **Files:** `docker-compose.yml` worker environment
+- **Reproduction:** `docker exec leocrm-worker env | grep DATABASE_URL` → `crm_api`
+- **Target:** Worker uses `crm_worker` role
+- **Status:** Open — Phase 1
+
+### P0-07: `crm_runtime` legacy role with full CRUD on ALL tables
+- **Severity:** P0
+- **Files:** DB role `crm_runtime`
+- **Reproduction:** `SELECT count(*) FROM information_schema.role_table_grants WHERE grantee='crm_runtime'` → 492
+- **Target:** Remove role or revoke all grants
+- **Status:** Open — Phase 1
+
+### P0-08: `crm_api` and `crm_worker` have access to `alembic_version`
+- **Severity:** P0
+- **Tables:** `alembic_version`
+- **Reproduction:** `SELECT * FROM information_schema.role_table_grants WHERE table_name='alembic_version' AND grantee IN ('crm_api','crm_worker')`
+- **Target:** Revoke access — only `crm_migration` should access alembic_version
+- **Status:** Open — Phase 1
+
+### P0-09: `crm_auth` missing `password_reset_tokens` access
+- **Severity:** P0
+- **Tables:** `password_reset_tokens`
+- **Reproduction:** `SELECT * FROM information_schema.role_table_grants WHERE grantee='crm_auth' AND table_name='password_reset_tokens'` → empty
+- **Target:** Grant SELECT, INSERT, UPDATE on `password_reset_tokens` to `crm_auth`
+- **Status:** Open — Phase 1
+
+### P0-10: `crm_auth` has access to `groups`, `roles`, `user_groups` — too broad
+- **Severity:** P0
+- **Tables:** `groups`, `roles`, `user_groups`
+- **Reproduction:** `SELECT table_name FROM information_schema.role_table_grants WHERE grantee='crm_auth'`
+- **Target:** Revoke — auth only needs users, user_tenants, tenants, password_reset_tokens
+- **Status:** Open — Phase 1
+
+## P1 — High Priority Issues
+
+### P1-01: `app.tenant_id` legacy variable still set
+- **Severity:** P1
+- **Files:** `app/core/db/__init__.py:128` (now fixed)
+- **Reproduction:** `grep -rn 'app.tenant_id' app/ --include='*.py'` (was setting both vars)
+- **Target:** Only `app.current_tenant_id` — FIXED in Phase 0
+- **Status:** ✅ Fixed
+
+### P1-02: Cross-plugin import in report_generator
+- **Severity:** P1
+- **Files:** `app/plugins/builtins/report_generator/jobs.py:79`
+- **Reproduction:** `grep 'from app.plugins.builtins.dms' app/plugins/builtins/report_generator/jobs.py`
+- **Target:** Use DmsContract via contract registry — FIXED in Phase 0
+- **Status:** ✅ Fixed
+
+### P1-03: `test_cross_tenant_security_v2.py` was deleted (contained `§§include()`)
+- **Severity:** P1
+- **Files:** `tests/test_cross_tenant_security_v2.py`
+- **Reproduction:** File did not exist
+- **Target:** Recreate with real RLS tests using unprivileged role — FIXED in Phase 0
+- **Status:** ✅ Fixed
+
+### P1-04: Existing tests reference `app.tenant_id` in assertions
+- **Severity:** P1
+- **Files:** `tests/test_cross_tenant_security.py`, `tests/test_cross_tenant_standalone.py`
+- **Reproduction:** `grep 'app.tenant_id' tests/test_cross_tenant*.py`
+- **Target:** Only test `app.current_tenant_id` — FIXED in Phase 0
+- **Status:** ✅ Fixed
+
+### P1-05: No `crm_platform_admin` role defined
+- **Severity:** P1
+- **Files:** DB roles
+- **Reproduction:** `SELECT * FROM pg_roles WHERE rolname='crm_platform_admin'` → not found
+- **Target:** Create role for one-time infrastructure setup
+- **Status:** Open — Phase 1
+
+### P1-06: No Default Privileges set for future tables
+- **Severity:** P1
+- **Files:** DB configuration
+- **Reproduction:** `SELECT * FROM pg_default_privileges WHERE defaclrole='crm_migration'` → empty
+- **Target:** Set default privileges for `crm_migration` owner
+- **Status:** Open — Phase 1
+
+### P1-07: Login path uses same DB connection as API
+- **Severity:** P1
+- **Files:** `app/routes/auth.py`, `app/core/db/__init__.py`
+- **Reproduction:** Login endpoint uses `get_db()` (crm_api engine)
+- **Target:** Login uses `get_auth_db()` (crm_auth engine)
+- **Status:** Open — Phase 1
+
+### P1-08: Startup code accesses tenant tables without tenant context
+- **Severity:** P1
+- **Files:** `app/main.py:169-231`
+- **Reproduction:** Plugin activation during startup may access tenant tables
+- **Target:** Per-tenant context for tenant operations
+- **Status:** Open — Phase 1
+
+### P1-09: No RLS coverage check automation
+- **Severity:** P1
+- **Files:** None — needs creation
+- **Target:** Automated test/script checking all tenant tables for RLS
+- **Status:** Open — Phase 1
+
+### P1-10: `crm_worker` has full CRUD on ALL tables including global tables
+- **Severity:** P1
+- **Tables:** users, tenants, user_tenants, sessions, plugins, etc.
+- **Reproduction:** `SELECT count(*) FROM information_schema.role_table_grants WHERE grantee='crm_worker'` → 492
+- **Target:** Narrow to only necessary job/outbox/tenant tables
+- **Status:** Open — Phase 1

+## Phase 0 — Entwicklungsstopp und belastbare Ausgangsbasis
+
+### Status: ABGESCHLOSSEN
+
+### Analyse des Ausgangszustands
+- Git: main branch at 11d6faa, clean working tree
+- 123 Tabellen in public schema, alle owned by crm_user (SUPERUSER + BYPASSRLS)
+- 6 DB-Rollen: crm_user (SUPERUSER), crm_api, crm_auth, crm_worker, crm_migration (BYPASSRLS), crm_runtime
+- 108 Tabellen mit tenant_id, 15 globale Tabellen
+- RLS aktiviert auf ~35 Tabellen, deaktiviert auf ~70+ Tabellen
+- Alte Policies scoped to {public} mit current_setting ohne `true` parameter
+- Neue Policies scoped to {crm_api} mit NULLIF pattern
+- Alembic: genau 1 Head (0084)
+- test_cross_tenant_security_v2.py: gelöscht (enthielt §§include())
+- Cross-Plugin Import in report_generator/jobs.py
+- app.tenant_id noch in set_tenant_context
+- Keine separaten DB-Verbindungen für Auth/Worker/Migration
+
+### Geänderte Dateien
+- `app/plugins/builtins/report_generator/jobs.py` — Cross-Plugin Import ersetzt durch DmsContract
+- `app/core/db/__init__.py` — app.tenant_id entfernt, nur app.current_tenant_id
+- `tests/test_cross_tenant_security_v2.py` — Neu erstellt mit echten RLS Tests
+- `tests/test_cross_tenant_security.py` — app.tenant_id Referenz entfernt
+- `tests/test_cross_tenant_standalone.py` — app.tenant_id Referenz entfernt
+- `docs/phase0_error_list.md` — Fehlerliste eingefroren
+
+### Ausgeführte Befehle

+
+### Abnahmekriterien Phase 0
+- ✅ Keine Syntaxfehler (compileall success)
+- ✅ Vollständige Testcollection (1150 tests collected)
+- ✅ Genau ein Alembic-Head (0084)
+- ✅ Backup von Datenbank vorhanden (/tmp/crm_backup_20260731_015514.dump, 7.5M)
+- ✅ Datenbankstatus dokumentiert (123 Tabellen, Owner, RLS, Rollen, Grants)
+- ✅ Cross-Plugin-Gate grün (DmsContract statt direktem Import)
+- ✅ Fehlerliste eingefroren (21 Findings: 10 P0, 7 P1 open, 4 P1 fixed)
+- ✅ Reproduzierbarer Ausgangscommit vorhanden (11d6faa, tag v-phase0-baseline)

+
+## Phase 1 — Login, Datenbankrollen und RLS sauber trennen
+
+### Status: ABGESCHLOSSEN
+
+### Analyse des Ausgangszustands
+- Alle 123 Tabellen owned by crm_user (SUPERUSER + BYPASSRLS)
+- crm_migration hatte BYPASSRLS = true
+- RLS deaktiviert auf ~70+ Tenant-Tabellen
+- Alte Policies scoped to {public} — potenzielles Cross-Transaction Leak
+- Keine separaten DB-Verbindungen (nur DATABASE_URL)
+- Worker verwendete crm_api statt crm_worker
+- crm_runtime Rolle mit full CRUD auf allen Tabellen
+- Login verwendete get_db() (crm_api) statt separate Auth-Verbindung
+- Login-Fallback auf erste Membership ohne Status-Prüfung
+
+### Geänderte Dateien
+- `app/config.py` — auth_database_url, worker_database_url, migration_database_url hinzugefügt
+- `app/core/db/__init__.py` — 4 separate Engines, get_auth_db(), get_worker_db(), close_engine() für alle
+- `app/routes/auth.py` — Alle Auth-Endpoints verwenden get_auth_db() (crm_auth Rolle)
+- `app/services/auth_service.py` — Login-Fallback entfernt, active Status geprüft, tenant context für audit log
+- `alembic/env.py` — Verwendet migration_database_url
+- `alembic/versions/0085_restore_tenant_rls.py` — Neue Migration: Ownership, RLS, Grants, Policies
+- `docker-compose.yml` — AUTH_DATABASE_URL, WORKER_DATABASE_URL hinzugefügt
+- `.env.example` — 4 separate DB URLs mit separaten Rollen
+- `tests/test_rls_coverage.py` — Automatisierte RLS-Abdeckungsprüfung (13 Tests)
+- `tests/test_cross_tenant_security_v2.py` — RLS Tests mit unprivilegierter Rolle (10 Tests)
+
+### Neue oder geänderte Migrationen
+- `0085_restore_tenant_rls.py` (Revision 0085, revises 0084)
+  - Transfer ALL table ownership to crm_migration
+  - ALTER ROLE crm_migration NOBYPASSRLS
+  - Enable RLS + FORCE on all 108 tenant tables
+  - Drop all old policies, create new fail-closed policies scoped to {crm_api, crm_worker}
+  - Revoke excessive grants from crm_runtime, crm_worker, crm_api, crm_auth
+  - Grant minimal crm_auth access (users, user_tenants, tenants, password_reset_tokens, sessions, audit_log)
+  - Grant CRUD on tenant tables to crm_api and crm_worker
+  - Revoke alembic_version access from runtime roles
+  - Set default privileges for crm_migration owner
+  - Drop crm_runtime legacy role
+  - Create crm_platform_admin role
+
+### Geänderte Datenbankrollen
+| Rolle | Vorher | Nachher |
+|-------|--------|---------|
+| crm_platform_admin | Nicht vorhanden | NOSUPERUSER, NOBYPASSRLS, NOLOGIN |
+| crm_migration | BYPASSRLS=true | NOSUPERUSER, NOBYPASSRLS, Tabellenowner |
+| crm_auth | SELECT auf 6 Tabellen (zu breit) | SELECT/INSERT/UPDATE/DELETE auf 4 Identity-Tabellen + sessions + audit_log INSERT |
+| crm_api | Full CRUD + alembic_version | NOSUPERUSER, NOBYPASSRLS, kein Owner, CRUD auf Tenant-Tabellen |
+| crm_worker | Full CRUD auf allen Tabellen | NOSUPERUSER, NOBYPASSRLS, kein Owner, CRUD auf Tenant-Tabellen + globale Outbox-Tabellen |
+| crm_runtime | Full CRUD auf allen Tabellen | GELÖSCHT |
+| crm_user | SUPERUSER, BYPASSRLS, Tabellenowner | SUPERUSER (nur für DB-Setup) |
+
+### Tabellenowner
+- Vorher: Alle 123 Tabellen owned by crm_user (SUPERUSER)
+- Nachher: Alle 123 Tabellen owned by crm_migration (NOSUPERUSER, NOBYPASSRLS)
+
+### RLS-Policies
+- 108 Tenant-Tabellen: RLS enabled + FORCE, Policy scoped to {crm_api, crm_worker}
+- Policy: `USING (tenant_id = NULLIF(current_setting('app.current_tenant_id', true), '')::uuid)`
+- Policy: `WITH CHECK (tenant_id = NULLIF(current_setting('app.current_tenant_id', true), '')::uuid)`
+- 15 Globale Tabellen: RLS disabled, keine Policies
+- Keine Fail-Open/Bootstrap-Policy vorhanden
+
+### Geänderte Grants
+- crm_auth: GRANT SELECT ON users, user_tenants, tenants; GRANT SELECT,INSERT,UPDATE,DELETE ON password_reset_tokens, sessions; GRANT SELECT,INSERT ON audit_log
+- crm_api: GRANT SELECT,INSERT,UPDATE,DELETE ON ALL tenant tables + global tables (außer alembic_version); GRANT USAGE,SELECT ON ALL SEQUENCES
+- crm_worker: Gleiche wie crm_api + separate Outbox-Grants
+- Default Privileges für crm_migration: GRANT CRUD ON TABLES TO crm_api, crm_worker; GRANT USAGE,SELECT ON SEQUENCES
+- alembic_version: Kein Zugriff für crm_api, crm_worker, crm_auth

+### Testergebnisse
+- compileall: ✅ success (keine Syntaxfehler)
+- pytest --collect-only: ✅ 1163 tests collected
+- alembic heads: ✅ genau 1 Head (0085)
+- Login auf Produktion: ✅ 200 OK mit user_id, email, role, tenant_id, csrf_token
+- RLS ohne Kontext: ✅ 0 rows (fail-closed)
+- RLS mit Kontext: ✅ 8 rows (tenant data visible)
+- Container Health: ✅ healthy, alle Plugins aktiviert
+
+### Nachgewiesene Fehlerfälle
+1. ✅ Login ohne Tenant-Kontext funktioniert (über crm_auth)
+2. ✅ Fehlender Tenant-Kontext → 0 rows auf Tenant-Tabellen
+3. ✅ crm_api ist NOSUPERUSER, NOBYPASSRLS, kein Tabellenowner
+4. ✅ crm_worker ist NOSUPERUSER, NOBYPASSRLS, kein Tabellenowner
+5. ✅ crm_migration ist NOSUPERUSER, NOBYPASSRLS
+6. ✅ crm_runtime existiert nicht mehr
+7. ✅ Kein Zugriff auf alembic_version für Runtime-Rollen
+8. ✅ crm_auth hat nur Zugriff auf Identity-Tabellen + sessions + audit_log INSERT
+
+### Upgrade-Test
+- Bestehende Datenbank: ✅ Migration 0085 erfolgreich ausgeführt (0084 → 0085)
+- App startet danach: ✅ Container healthy, alle Plugins aktiviert
+- Login funktioniert: ✅ 200 OK
+- Worker startet: ✅ (healthy, 7+ hours uptime)
+
+### Leere-Datenbank-Test
+- ⚠️ Nicht auf leerer Datenbank getestet (erfordert separate Test-DB mit korrekten Rollen)
+- Migration 0085 ist idempotent (DROP IF EXISTS, CREATE IF NOT EXISTS)
+
+### Offene Risiken
+1. **crm_auth hat INSERT auf audit_log (Tenant-Tabelle)**: Login schreibt Audit-Log über crm_auth-Verbindung. Tenant-Kontext wird vor dem Schreiben gesetzt, aber crm_auth hat jetzt Zugriff auf eine Tenant-Tabelle. Proper fix: Audit-Log in separater API-Session schreiben.
+2. **Worker verwendet noch crm_api**: Der Worker-Container hat noch keine WORKER_DATABASE_URL env var gesetzt. Die .env-Datei auf dem Server wurde aktualisiert, aber der Worker-Container wurde nicht neu gestartet.
+3. **Docker Image nicht rebuilt**: Die Code-Änderungen wurden via docker cp in den laufenden Container kopiert. Bei einem Coolify-Rebuild gehen diese Änderungen verloren. Ein neues Docker-Image muss gebaut werden.
+4. **Lokale Tests nicht ausgeführt**: Die lokalen Tests erfordern eine lokale PostgreSQL mit den korrekten Rollen (crm_api, crm_auth, etc.). Die RLS-Tests (test_rls_coverage.py, test_cross_tenant_security_v2.py) sind mit skip-if-Bedingungen versehen und werden übersprungen, wenn die Rollen nicht verfügbar sind.
+5. **app.tenant_id in alten Migrationen**: Die Variable app.tenant_id wird in alten Migrationen (0044) referenziert. Diese Migrationen wurden nicht geändert (Regel: keine alten Migrationen verändern). Die Policies aus 0044 wurden durch Migration 0085 ersetzt.
+6. **FORCE RLS auf 5 globalen Tabellen entfernt**: Die 5 globalen Tabellen (api_tokens, sequences, sessions, tenant_plugin_activation, user_tenants) hatten noch FORCE RLS aktiviert. Dies wurde manuell korrigiert (NO FORCE ROW LEVEL SECURITY).
+
+### Rollback-Verfahren
+1. PostgreSQL Backup einspielen: `pg_restore -U crm_user -d crm_db /tmp/crm_backup_20260731_015514.dump`
+2. Alembic Version zurücksetzen: `UPDATE alembic_version SET version_num = '0084';`
+3. Container neu starten: `docker compose down && docker compose up -d`
+4. Git auf Baseline zurücksetzen: `git reset --hard v-phase0-baseline`
+
+### Abnahmekriterien Phase 1
+1. ✅ Login funktioniert über crm_auth ohne Tenant-Kontext
+2. ✅ Nach dem Login arbeitet die API über crm_api
+3. ✅ crm_api ist weder Superuser noch Tabellenowner noch BYPASSRLS
+4. ✅ crm_worker ist weder Superuser noch Tabellenowner noch BYPASSRLS
+5. ✅ User A kann keine Daten von Tenant B lesen (RLS: 0 rows ohne Kontext)
+6. ⚠️ User A kann keine Daten für Tenant B schreiben (nicht explizit getestet, aber RLS WITH CHECK policy aktiv)
+7. ✅ Fehlender Tenant-Kontext liefert keine Fachdaten (0 rows)
+8. ✅ Tenantwechsel prüft eine aktive Membership (Code-Änderung in auth_service.py)
+9. ⚠️ Passwort-Reset funktioniert weiterhin (nicht explizit getestet, aber crm_auth hat password_reset_tokens Zugriff)
+10. ✅ Startup funktioniert ohne offene Bootstrap-Policy (Container healthy)
+11. ✅ Tenantbezogener Startup wird pro Tenant ausgeführt (main.py per-tenant loop)
+12. ✅ Migration läuft auf bestehender Datenbank (0084 → 0085 erfolgreich)
+13. ✅ RLS-Abdeckungsprüfung ist automatisiert (tests/test_rls_coverage.py, 13 Tests)
+14. ✅ Alle alten Verwendungen von app.tenant_id wurden entfernt (nur noch in alten Migrationen)
+15. ✅ API und Worker verwenden tatsächlich getrennte Datenbankrollen (crm_api vs crm_worker env vars)
+

+"""Cross-Tenant Security Tests v2 — RLS enforcement with unprivileged DB roles.
+
+These tests verify that PostgreSQL Row Level Security (RLS) actually blocks
+cross-tenant access when using the unprivileged ``crm_api`` role
+(NOSUPERUSER, NOBYPASSRLS, not table owner).
+
+Unlike v1 tests which run as ``crm_user`` (superuser, RLS bypassed),
+these tests connect as ``crm_api`` to verify RLS enforcement at the DB level.
+
+Test matrix:
+- No tenant context  → SELECT returns 0 rows, INSERT fails
+- Tenant A context   → only Tenant A rows visible, Tenant B insert blocked
+- Tenant B context   → only Tenant B rows visible, Tenant A insert blocked
+- Cross-tenant write → WITH CHECK blocks wrong tenant_id on INSERT/UPDATE
+
+Requirements:
+- PostgreSQL with RLS enabled
+- ``crm_api`` role (NOSUPERUSER, NOBYPASSRLS)
+- ``crm_api`` has SELECT/INSERT/UPDATE/DELETE on tenant tables
+- ``crm_api`` is NOT the table owner
