docs: update README, changelog, phases — remove Ollama/NVIDIA refs, current model config, migration history

- AgentsController.SaveConfigFile: catch UnauthorizedAccessException and IOException
  instead of letting them bubble up unhandled; return clean 500 with logged message
- compose.yaml: add deploy.resources.limits.memory and reservations.memory for
  api (512M/128M), web (128M/32M), postgres (256M/64M)

-# Trigger CI
+
+## CI/CD
+
+### CI — Automatic
+
+Every push to `main` triggers `.gitea/workflows/ci.yaml`:
+- **Backend**: .NET restore → build → test
+- **Frontend**: pnpm install → type-check → test → build
+- **Security**: Scan for hardcoded secrets in source code
+
+CI must never break. If it does, Reviewer fixes.
+
+### CD — Auto + Manual (CD v3)
+
+Deployment can happen automatically or manually:
+
+#### Auto-Deploy (after successful CI on main)
+
+- Triggered by `workflow_run` after `CI - Build & Test` succeeds on `main`
+- Uses safe defaults: `patch` bump, all services, main ref
+- Skips automatically if the triggering commit contains `[skip ci]` (version-bump commits)
+- The version-bump commit itself uses `[skip ci]` → no infinite CI→Deploy→Bump→CI loops
+
+#### Manual Deploy (`workflow_dispatch`)
+
+1. DevOps triggers `Deploy to Production` in Gitea Actions (or Iris auto-approves)
+2. Chooses version bump type: patch (default) / minor / major
+3. Optionally scopes to a single service or specific git ref
+4. Workflow bumps VERSION, creates git tag, builds and deploys
+5. Health check + smoke test verify the deployment
+
+#### Rollback (`workflow_dispatch`)
+
+1. DevOps triggers `Rollback to Previous Version` in Gitea Actions
+2. Enters target git tag (e.g. `v0.2.49`) + confirmation `ROLLBACK`
+3. Workflow checks out the tag, rebuilds with `--no-cache`, redeploys
+4. Health check + smoke test verify the rollback
+
+#### Database Backup (`workflow_dispatch`)
+
+1. DevOps triggers `Database Backup` in Gitea Actions
+2. Optionally also copies backup to a host path (`/home/projekte_bao/backups`)
+3. Workflow dumps PostgreSQL via `pg_dumpall`, gzips, and uploads as a Gitea artifact
+4. Artifacts are retained for 90 days (configurable)
+5. Optional nightly schedule (uncomment the cron trigger in `backup.yaml`)
+
+#### Failure Handling
+
+When deploy or rollback fails:
+- **DevOps (Architekt)** analyses the error
+- **Reviewer (Code-Fixer)** fixes the problem
+- **DevOps** re-deploys to verify the fix
+
+The workflow outputs a formatted handoff message with the job URL.

 # Deployment
 
-> Letzte Aktualisierung: 2026-06-09
-> Status: ✅ Deployment abgeschlossen
+> Letzte Aktualisierung: 2026-06-13
+> Status: ✅ CD v3 (Auto + Manual)
 > Live-URL: https://nexus.noveria.net
 
-## Ziel
+## CD-Philosophie (v3)
 
-Nach Phase 1 soll das Mission-Control-Board deployt und die Infrastruktur so gesetzt sein, dass Bao direkt draufkommen kann.
+- **CI läuft automatisch** bei jedem Push → darf nie brechen
+- **CD auto + manuell**: Automaticher Deploy nach CI-Success auf main (patch default), manueller Deploy mit voller Kontrolle via `workflow_dispatch`
+- **Loop-Schutz**: Version-Bump-Commits enthalten `[skip ci]` — kein Re-Trigger der CI, kein Infinite-Loop
+- **Main-Deploys** duerfen VERSION bumpen und einen Git-Tag setzen
+- **Nicht-Main-Deploys** (anderer `git_ref`) deployen read-only und mutieren Git nicht
+- **Rollback** als eigener Workflow, manuell triggerbar
+- **Database-Backup** als eigener Workflow, manuell triggerbar (optionaler Nightly-Schedule)
+
+## Workflows
+
+### Deploy (`.gitea/workflows/deploy.yaml`)
+
+**Trigger**:
+- **Automatisch**: Nach erfolgreicher CI (`workflow_run` auf `CI - Build & Test`)
+  → Default-Parameter: patch bump, all services, main ref
+- **Manuell**: Via Gitea Actions → `workflow_dispatch`
+
+**Loop-Schutz**:
+- Version-Bump-Commits enthalten `[skip ci]` → Gitea startet keine neue CI
+- Auto-Deploy prüft zusätzlich `github.event.workflow_run.head_commit.message` auf `[skip ci]`
+- Beide Mechanismen zusammen verhindern Endlosschleife: CI → Deploy → Bump → CI …
+
+**Inputs** (nur bei `workflow_dispatch`):
+| Input | Typ | Default | Beschreibung |
+|---|---|---|---|
+| `version_bump` | choice (patch/minor/major) | patch | Version-Bump-Typ |
+| `service` | string | (all) | Einzelner Service oder alle |
+| `no_cache` | boolean | false | Docker-Build-Cache deaktivieren |
+| `git_ref` | string | main | Branch/Tag/Commit zum Deployen |
+
+**Ablauf**:
+1. Job-Level-Guard: Auto-Deploys fuer `[skip ci]`-Commits werden gar nicht gestartet
+2. Checkout des gewählten Git-Refs
+3. Wenn `git_ref = main`: Version-Bump + Git-Tag + Push
+4. Wenn `git_ref != main`: VERSION nur lesen, kein Push, kein Tag
+5. **Safe Secret Handling**: `.env` wird aus Secret-Umgebungsvariablen in `/tmp/nexus-deploy-env` geschrieben (mode 600), **NICHT** im Workspace
+6. Code-Sync zum Host-Deploy-Pfad
+7. `docker compose build && up -d --wait --force-recreate`
+8. `.env`-Tempfile wird mit `shred` gelöscht
+9. Health-Check (exponentieller Backoff, 6 Versuche)
+10. Smoke-Test (`/dashboard`, `/health`, `/api/v1/operations/snapshot` erwartet `401`)
+11. Bei Fehler: Reviewer-Handoff-Meldung mit Job-URL
+
+### Backup (`.gitea/workflows/backup.yaml`)
+
+**Trigger**: Manuell via Gitea Actions → `workflow_dispatch` (optional: Nightly-Schedule via Cron)
+
+**Inputs**:
+| Input | Typ | Default | Beschreibung |
+|---|---|---|---|
+| `keep_on_host` | boolean | false | Backup auch auf Host-Pfad kopieren |
+| `host_backup_path` | string | `/opt/openclaw/backups` | Host-Zielpfad |
+
+**Ablauf**:
+1. Backup-ID generieren (Timestamp-basiert)
+2. `docker exec nexus-postgres-1 pg_dumpall -U nexus` → gzip
+3. Upload als Gitea-Artifact (90 Tage Retention, bereits komprimiert)
+4. Optional: Kopie auf Host-Pfad via Docker-Volume-Mount
+5. Integritäts-Check: gzip-Test + SQL-Header-Validierung
+6. Backup-Summary mit Restore-Befehl
+
+**Restore (manuell auf dem Host)**:
+```bash
+# Aus Gitea-Artifact herunterladen oder von Host-Pfad:
+zcat nexus-backup-YYYY-MM-DDTHHMMSSZ.sql.gz | docker exec -i nexus-postgres-1 psql -U nexus -d postgres
+# Danach Stack neu starten:
+cd /opt/openclaw/data/openclaw/workspace/nexus
+docker compose up -d --wait
+```
+
+**Nightly-Schedule aktivieren**:
+In `backup.yaml` die Zeilen auskommentieren:
+```yaml
+schedule:
+  - cron: '0 3 * * *'  # Jede Nacht um 03:00 UTC
+```
+
+### Rollback (`.gitea/workflows/rollback.yaml`)
+
+**Trigger**: Manuell via Gitea Actions → `workflow_dispatch`
+
+**Inputs**:
+| Input | Typ | Beschreibung |
+|---|---|---|
+| `target_tag` | string | Git-Tag zum Zurückrollen (z.B. `v0.2.49`) |
+| `confirm` | string | Muss exakt `ROLLBACK` sein (Safety-Gate) |
+
+**Ablauf**:
+1. Safety-Gate: Bestätigungstext muss `ROLLBACK` sein
+2. Checkout des Target-Tags
+3. Tag-Validierung (existiert? welcher Commit?)
+4. Safe Secret Handling (gleiches Tempfile-Pattern)
+5. Code-Sync des alten Stands zum Host
+6. `docker compose build --no-cache && up -d --wait --force-recreate`
+7. Health-Check + Smoke-Test (`/dashboard`, `/health`, `/api/v1/operations/snapshot` erwartet `401`)
+8. Bei Fehler: Reviewer-Handoff mit manueller Rollback-Anleitung
+
+**DB-Migration bei Rollback**: Die API führt `MigrateAsync` beim Start aus. Wenn die Migrationen des Rollback-Tags ein Prefix der aktuellen DB sind (Normalfall), läuft EF Core sie als No-Op. Wenn ein Rollback-Tag vor einer destruktiven Migration liegt, ist manuelles DB-Intervention nötig — ein Edge Case, der DevOps signalisiert wird.
 
 ## Secrets und Konfiguration
 
-- [x] `.env.template` mit allen erforderlichen Variablen erstellt
-- [x] Produktions-`.env` mit starken, getrennten Secrets angelegt
-- [x] Migration des Produktionsstacks getestet
+### Secrets in Gitea
+
+Folgende Secrets sind in Gitea (Repo → Settings → Actions → Secrets) konfiguriert:
+
+| Secret | Verwendung |
+|---|---|
+| `ENV_POSTGRES_PASSWORD` | PostgreSQL-Passwort |
+| `ENV_JWT_KEY` | JWT-Signing-Key (min. 32 Bytes) |
+| `ENV_OWNER_PASSWORD` | Owner-Account-Passwort |
+| `ENV_OPENCLAW_TOKEN` | OpenClaw Gateway Token |
+
+### Safe Secret Handling (v3)
+
+**Vorher (unsicher)**: Secrets wurden via `${{ secrets.X }}` direkt in eine Datei im Workspace interpoliert, die dann zum Host synct wurde. Das `.env` lag potenziell lesbar im Workspace und auf dem Host-Dateisystem.
+
+**Jetzt (sicher)**:
+1. Secrets werden als Step-Environment aus Gitea Secrets bezogen und erst dann in `/tmp/nexus-deploy-env` (mode 600) geschrieben
+2. Die Temp-Datei wird via `docker run -v` als read-only ins Compose-Environment gemountet
+3. Nach Deploy/Rollback wird die Datei mit `shred -u` gelöscht
+4. Das `.env` erscheint **nie** im Workspace oder auf dem Host-Deploy-Pfad

+## Incident-Hinweis (2026-06-14)
+
+- Verifizierter Ausfallpfad: `api` konnte wegen DB-Passwort-Mismatch nicht healthy werden; dadurch blieb `web` per `depends_on: service_healthy` im Status `Created`.
+- Nach einem isolierten API-Fix startet `web` nicht automatisch nach. Sicherer Minimalpfad:
+  1. `docker compose ps`
+  2. `curl http://127.0.0.1:18880/health`
+  3. Falls `health=200`, aber `/dashboard` noch nicht `200` und `web` auf `Created` steht: `docker compose up -d web`
+  4. Danach extern `/dashboard`, `/health` und `/api/v1/operations/snapshot` erneut prüfen
+- Der manuelle Helper [`ops/deploy.sh`](/home/node/.openclaw/workspace/nexus/ops/deploy.sh) verifiziert deshalb jetzt nicht mehr nur `/health`, sondern auch `/dashboard` und den Auth-Schutz der Operations-API.
+
 ## Offene Arbeit
 
-- [ ] Backup-Strategie fuer Produktionsdaten definieren
+- [ ] Docker-Socket-Risiko im CD-Workflow final adressieren (kommt spaeter)
 - [ ] Docker-Logs und Container-Health-Monitoring einrichten
-- [ ] `.gitignore` final pruefen
+- [ ] Restore-Drill fuer Backup/Recovery einmal realistisch durchspielen und dokumentieren
+- [ ] Direkt-Pushes auf `main` waehrend eines Main-Deploys organisatorisch vermeiden oder spaeter technisch haerter absichern

+### Deploy-Trigger-Actor (2026-06-14)
+
+- Deploy-Trigger werden durch DevOps (nicht Iris) ausgelöst
+- Git-Remote origin verwendet DevOps-Token → Gitea zeigt devops als Actor
+- Workflow-Dispatch API-Calls mit DevOps-Token authentifizieren
