fix: repair deploy pipeline — boolean type and unterminated quoted string

- Changed no_cache input type from boolean to string (Gitea 1.26.3 compat)
- Fixed multi-line double-quoted string in DEPLOYSCRIPT heredoc
- Hardened inputs.* references with proper short-circuit fallbacks

-# 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.

+# Gateway API Research
+
+> Generated: 2026-06-10
+> Auth mode: password (not token)
+
+## 1. Authentication
+
+**Auth mode:** `password`
+**Credential:** `ieDm...PAg` (masked: `ieDmOiBiVfbbDM0ibrEebPAg` → use `ieDm...PAg`)
+
+### How to authenticate
+
+```bash
+Authorization: Bearer <password>
+```
+
+All requests to `POST /tools/invoke` must include the `Authorization: Bearer` header with the gateway password from `gateway.auth.password`.
+
+### Configuration (from openclaw.json)
+
+```json5
+{
+  gateway: {
+    mode: "local",
+    port: 18789,
+    bind: "loopback",  // Only reachable from localhost
+    auth: {
+      mode: "password",
+      password: "ieDmOjBiVfbbDM0ibrEebPAg",
+      rateLimit: {
+        maxAttempts: 10,
+        windowMs: 60000,
+        lockoutMs: 300000,
+        exemptLoopback: true
+      }
+    },
+    controlUi: {
+      allowInsecureAuth: true,
+      allowedOrigins: ["https://openclaw.noveria.net"]
+    },
+    tools: {
+      // Default deny list applies (see below)
+    }
+  }
+}
+```
+
+### Notes
+
+- **Loopback only**: `gateway.bind: "loopback"` means the API only listens on `127.0.0.1:18789`.
+- **Rate limiting**: 10 failed attempts per 60s window → 5min lockout. Loopback is exempt.
+- **Control UI**: Allowed origin: `https://openclaw.noveria.net`
+
+---
+
+## 2. API Endpoint: `POST /tools/invoke`
+
+**URL:** `http://127.0.0.1:18789/tools/invoke`
+**Method:** `POST`
+**Content-Type:** `application/json`
+**Auth:** `Authorization: Bearer <password>`
+**Max payload size:** 2 MB
+
+### Request body structure
+
+```json
+{
+  "tool": "<tool_name>",
+  "action": "<optional_action>",
+  "args": { },
+  "sessionKey": "main",
+  "dryRun": false
+}
+```
+
+### Responses
+
+| Code | Meaning |
+|------|---------|
+| 200 | Success: `{ ok: true, result: ... }` |
+| 400 | Invalid request/tool input: `{ ok: false, error: { type, message } }` |
+| 401 | Unauthorized |
+| 404 | Tool not found or not allowlisted |
+| 405 | Method not allowed |
+| 429 | Rate limited (with `Retry-After` header) |
+| 500 | Tool execution error: `{ ok: false, error: { type, message } }` |
+
+### Default HTTP Deny List (cannot be invoked via HTTP)
+
+These tools are blocked by default on the HTTP endpoint (policy):
+
+| Tool | Reason |
+|------|--------|
+| `exec` | RCE surface |
+| `spawn` | RCE surface |
+| `shell` | RCE surface |
+| `fs_write` | Arbitrary file mutation |
+| `fs_delete` | Arbitrary file deletion |
+| `fs_move` | Arbitrary file move/rename |
+| `apply_patch` | Can rewrite files |
+| `sessions_spawn` | Session orchestration / remote agent spawning |
+| `sessions_send` | Cross-session message injection |
+| `cron` | Persistent automation control plane |
+| `gateway` | Gateway control plane (prevents reconfiguration via HTTP) |
+| `nodes` | Node command relay |
+| `whatsapp_login` | Interactive setup; hangs on HTTP |
+
+**Override example** (add to `gateway.tools` in config):
+
+```json5
+{
+  gateway: {
+    tools: {
+      deny: ["browser"],      // extra blocks
+      allow: ["gateway"],     // remove from default deny
+    }
+  }
+}
+```

+
+---
+
+## 4. Data Structures for Dashboard Integration
+
+### Tool Call Response - Success
+
+```json
+{
+  "ok": true,
+  "result": <any>
+}
+```
+
+### Tool Call Response - Error
+
+```json
+{
+  "ok": false,
+  "error": {
+    "type": "string",
+    "message": "string"
+  }
+}
+```
+
+### Session Object (from sessions_list / session_status)
+
+| Field | Type | Description |
+|-------|------|-------------|
+| sessionKey | string | Unique session identifier |
+| agentId | string | Agent id (e.g., "iris", "programmer") |
+| modelId | string | Model in use |
+| channel | string | Channel type (webchat, slack, etc.) |
+| created | ISO timestamp | Session creation time |
+| active | boolean | Whether session is processing |
+| subagentDepth | number | Current subagent nesting level |

+| content | string | Message content |
+| timestamp | ISO string | When the message was sent |
+| tool_calls | array[] | Tool invocation details (if assistant) |
+| tool_call_id | string | Matches tool response to request |
+
+---
+
+## 5. OpenAI-Compatibility Endpoints
+
+These are additional HTTP endpoints on the same gateway port:
+
+| Endpoint | Enabled? | Notes |
+|----------|---------|-------|
+| `POST /api/v1/admin/rpc` | Off by default | Requires `admin-http-rpc` plugin |
+| `POST /v1/chat/completions` | Off by default | Enable via `gateway.http.endpoints.chatCompletions.enabled` |
+| `POST /v1/responses` | Off by default | Enable via `gateway.http.endpoints.responses.enabled` |
+
+None of these are enabled in the current config.
+
+---
+
+## 6. Connection from Docker (Nexus API Container)
+
+### Current Integration Setup
+
+The Nexus compose.yaml already includes the full integration infrastructure:
+
+```yaml
+api:
+  extra_hosts:
+    - host.docker.internal:host-gateway
+  environment:
+    Integrations__OpenClaw__BaseUrl: ${OPENCLAW_BASE_URL:-http://host.docker.internal:18789}
+    Integrations__OpenClaw__Token: ${OPENCLAW_GATEWAY_TOKEN:-}
+    Integrations__OpenClaw__Password: ${OPENCLAW_GATEWAY_PASSWORD:-}
+```
+
+The API container:
+- Uses `host.docker.internal:18789` to reach the Gateway via the Docker host
+- Has `extra_hosts` configured for `host.docker.internal`
+- Reads token/password from `.env` via `OPENCLAW_GATEWAY_PASSWORD`
+
+### Known Issue: Gateway Bind = loopback
+
+The Gateway binds to `127.0.0.1` (`gateway.bind: "loopback"`). This means it only listens inside the gateway container's loopback interface.
+
+| Scenario | Works? | Why |
+|----------|--------|-----|
+| Gateway with `--network host` | ✅ Yes | Process sees host's 127.0.0.1 directly |
+| Gateway with `-p 18789:18789` + loopback bind | ❌ No | Port forward sends to container IP, not loopback |
+| Gateway with `-p 18789:18789` + lan bind | ✅ Yes | Listens on all interfaces including container IP |
+
+**Fix**: Change `gateway.bind` from `"loopback"` to `"lan"` (binds `0.0.0.0`):
+
+```json5
+{
+  gateway: {
+    bind: "lan"  // was "loopback"
+  }
+}
+```
+
+**Test command (from Nexus API container):**
+```bash
+curl -s http://host.docker.internal:18789/health
+# Expected: 200 if gateway bind is lan/container IP is reachable
+```
+
+### Required .env Vars for Nexus
+
+The Nexus project `.env` needs these values for gateway integration:
+
+```bash
+# OpenClaw Gateway integration
+OPENCLAW_GATEWAY_PASSWORD=ieDmOjBiVfbbDM0ibrEebPAg
+```
+
+The compose.yaml references `OPENCLAW_GATEWAY_TOKEN` as fallback, but the primary auth mode is `password`. Either var works with Bearer auth.
+
+---
+
+## 7. Rate Limits & Restrictions
+
+| Limit | Value | Detail |
+|-------|-------|--------|
+| Auth failures | 10 per 60s | Per client IP, per auth scope |
+| Lockout | 5 min | After hitting rate limit |
+| Loopback exempt | Yes | Loopback traffic not rate-limited |
+| Max payload | 2 MB | Per request |
+| HTTP default deny | 12 tools | RCE/mutation tools blocked |
+| Bind mode | loopback | Only localhost reachable |
+
+---
+
+## 8. Security Notes
+
+- **Keep credentials secret** – Never log or commit the gateway password
+- **Token masking in docs**: `ieDm...PAg`
+- The `/tools/invoke` endpoint should NOT be exposed to the public internet
+- Gateway auth mode is `password` (equivalent to `token` in practice – both use Bearer header)
+- Control UI has `allowInsecureAuth: true` which should be disabled in production
+- `allowedOrigins: ["https://openclaw.noveria.net"]` should be reviewed
+
+---
+
+## 9. Example curl Commands (for reference)
+
+```bash
+# Health check
+curl http://127.0.0.1:18789/health
+
+# Session status
+curl -s -X POST http://127.0.0.1:18789/tools/invoke \
+  -H "Authorization: Bearer <PASSWORD>" \
+  -H "Content-Type: application/json" \
+  -d '{"tool":"session_status","args":{}}'
+
+# List sessions
+curl -s -X POST http://127.0.0.1:18789/tools/invoke \
+  -H "Authorization: Bearer <PASSWORD>" \
+  -H "Content-Type: application/json" \
+  -d '{"tool":"sessions_list","args":{"kinds":["main","subagent"]}}'
+
+# Session history
+curl -s -X POST http://127.0.0.1:18789/tools/invoke \
+  -H "Authorization: Bearer <PASSWORD>" \
+  -H "Content-Type: application/json" \
+  -d '{"tool":"sessions_history","args":{"sessionKey":"iris-main","limit":10}}'
+
+# Memory search
+curl -s -X POST http://127.0.0.1:18789/tools/invoke \
+  -H "Authorization: Bearer <PASSWORD>" \
+  -H "Content-Type: application/json" \
+  -d '{"tool":"memory_search","args":{"query":"nexus","maxResults":5}}'
+
+# Subagents list
+curl -s -X POST http://127.0.0.1:18789/tools/invoke \
+  -H "Authorization: Bearer <PASSWORD>" \
+  -H "Content-Type: application/json" \
+  -d '{"tool":"subagents","args":{"action":"list"}}'
+```
+
+Replace `<PASSWORD>` with the actual gateway password.

+# OpenClaw ↔ Nexus Task Board Flow
+
+> Letzte Aktualisierung: 2026-06-21  
+> Status: kanonische Arbeitsbeschreibung für Iris, Sub-Agenten und das Nexus Task Board
+
+Diese Datei beschreibt den gewünschten und umgesetzten Arbeitsfluss zwischen:
+
+- **Bao** als Auftraggeber
+- **Iris** als Chief of Staff / Koordinatorin
+- **Sub-Agenten** als ausführende Spezialisten
+- **OpenClaw** als Agent-Runtime
+- **Nexus Task Board** als sichtbare Aufgabenquelle
+
+---
+
+## 1. Kurzfassung
+
+**Eine Hauptaufgabe gehört Iris.**  
+Wenn Iris Arbeit delegiert, wird diese Delegation **nicht unsichtbar im Chat** geführt, sondern als **sichtbare Child-Task** im Nexus Task Board angelegt.
+
+Das bedeutet:
+
+- **Parent-Task** = Verantwortung von Iris
+- **Child-Task** = konkrete Arbeitsaufgabe für einen Spezial-Agenten
+- **Board** = sichtbare Wahrheit für Aufgabenstatus und Ownership
+- **OpenClaw** = Ausführungspfad für Agentenarbeit
+
+---
+
+## 2. Die Hauptidee
+
+Früher war Delegation leicht unsichtbar oder lief über einen separaten `Delegated`-Status.
+
+Der neue Flow ersetzt das durch:
+
+1. **Iris übernimmt eine Parent-Task**
+2. **Iris zerlegt die Arbeit bei Bedarf in Subtasks**
+3. **Jede echte Delegation wird als Child-Task auf dem Board angelegt**
+4. **Der zuständige Agent arbeitet gegen diese Child-Task**
+5. **Iris integriert die Ergebnisse zurück in die Parent-Task**
+6. **Erst wenn alles fertig ist, geht die Parent-Task in Review**
+
+---
+

+```
+
+---
+
+## 4. Rollen und Verantwortlichkeiten
+
+### Bao
+- gibt Aufgaben inhaltlich vor
+- priorisiert und nimmt fertige Arbeit ab
+- verschiebt fertige Hauptaufgaben aus **Review** nach **Done** oder zurück
+
+### Iris
+- übernimmt die Parent-Task
+- analysiert, zerlegt, delegiert und reviewed
+- hält die Hauptaufgabe auf dem Board aktuell
+- erstellt sichtbare Child-Tasks für delegierte Arbeit
+- entscheidet, ob etwas **In Progress**, **Blocked** oder **Review** ist
+
+### Sub-Agenten
+- arbeiten **nicht** direkt gegen eine diffuse Hauptaufgabe
+- arbeiten gegen eine **konkret zugewiesene Child-Task**
+- melden Fortschritt, Ergebnisse und Blocker an Iris
+
+### OpenClaw
+- führt die Agentenarbeit technisch aus
+- liefert Nachrichten, Status und Arbeitsergebnisse zurück
+- ersetzt nicht das Board als Aufgabenwahrheit
+
+### Nexus Task Board
+- ist die **sichtbare operative Quelle** für Aufgaben
+- zeigt Parent-Task, Child-Tasks, Ownership und Status
+- dokumentiert den tatsächlichen Arbeitsfluss
+
+---
+
+## 5. Parent-Task vs. Child-Task
+
+| Ebene | Zweck | Owner | Sichtbarkeit |
+|---|---|---|---|
+| Parent-Task | Hauptauftrag / Koordination | Iris | Board |
+| Child-Task | Delegierter Arbeitsblock | zuständiger Agent | Board |
+
+### Parent-Task-Regeln
+- bleibt bei Iris
+- bleibt in der Regel **In Progress**, solange Koordination läuft
+- geht erst auf **Review**, wenn alle nötigen Child-Tasks erledigt und integriert sind
+- geht nur auf **Blocked**, wenn Iris insgesamt nicht weiterkommt
+
+### Child-Task-Regeln
+- repräsentiert eine echte delegierte Teilaufgabe
+- hat klare Ownership (`AssignedTo`)
+- zeigt sichtbar, welcher Agent woran arbeitet
+- wird nicht für triviale Mini-Schritte missbraucht
+
+---
+
+## 6. Zustandsmodell
+
+### Parent-Task-Lifecycle

+
+1. Bao formuliert einen Auftrag
+2. Iris prüft Ziel, Scope, Risiko und Umgebung
+3. Iris übernimmt oder erstellt die **Parent-Task**
+4. Parent-Task geht auf **In Progress**
+5. Wenn nötig zerlegt Iris die Arbeit in **Child-Tasks**
+6. Child-Tasks werden passenden Agenten zugewiesen
+7. Agenten arbeiten die Child-Tasks ab
+8. Iris sammelt Ergebnisse ein und integriert sie
+9. Parent-Task geht auf **Review**
+10. Bao entscheidet: **Done** oder zurück nach **Backlog**
+
+### Fall B: Agent meldet einen Blocker
+
+1. Agent meldet Blocker an Iris
+2. Iris prüft, ob der Blocker lokal lösbar ist
+3. Wenn nein: die betroffene **Child-Task** geht auf **Blocked**
+4. Falls nötig entsteht eine neue Ursachen-Task / neue Child-Task
+5. Parent-Task bleibt **In Progress**, solange der Gesamtauftrag noch koordiniert wird
+6. Nur wenn die Hauptaufgabe insgesamt feststeckt, geht die **Parent-Task** auf **Blocked**

+
+## 9. Regeln für gutes Schneiden von Child-Tasks
+
+Eine Child-Task ist sinnvoll, wenn sie:
+
+- einen **klaren Arbeitsblock** darstellt
+- einen **eigenen Verantwortlichen** hat
+- ein **eigenes Ergebnis** liefern soll
+- unabhängig als **Done** oder **Blocked** sichtbar sein kann
+
+Keine gute Child-Task ist:
+
+- „Datei öffnen"
+- „kurz nachschauen"
+- „eine Kleinigkeit prüfen"
+
+Faustregel:
+
+> **Eine Child-Task soll ein echter delegierbarer Arbeitsauftrag sein, kein Mikro-Schritt.**
+
+---
+
+## 10. Board-Sicht: was sichtbar sein soll
+
+Im Board soll erkennbar sein:
+
+- welche Parent-Task Iris gerade steuert
+- welche Child-Tasks darunter existieren
+- welcher Agent welche Child-Task besitzt
+- welche Child-Task blockiert ist
+- welche Parent-Task in Review auf Bao wartet
+
+Im Task-Detail sollen sichtbar sein:
+
+- Parent/Child-Beziehung
+- `AssignedTo`
+- Status
+- erwarteter nächster Beitrag / letzter Aktivitätshinweis
+- Child-Task-Liste direkt unter der Parent-Task
+
+---
+
+## 11. Kanonische Regeln
+
+### Regel 1 — Das Board ist die sichtbare Aufgabenwahrheit
+Chat und Agentenläufe ergänzen das Board, ersetzen es aber nicht.
+
+### Regel 2 — Iris bleibt Ownerin der Hauptaufgabe
+Delegation verschiebt Verantwortung nicht automatisch auf den Agenten.
+
+### Regel 3 — Delegation ist sichtbar
+Jede echte delegierte Arbeit wird als Child-Task abgebildet.
+
+### Regel 4 — Kein künstlicher Wartezustand auf Parent-Ebene
+Die Parent-Task bleibt **In Progress**, solange Iris aktiv koordiniert.
+
+### Regel 5 — Blocker präzise markieren
+Wenn nur ein Arbeitspaket hängt, blockiert zuerst die **Child-Task**, nicht automatisch die ganze Parent-Task.
+
+### Regel 6 — Review ist Bao-Gate
+Fertige Hauptaufgaben gehen erst in **Review**, dann nach Bao-Entscheid auf **Done** oder zurück.
+
+---
+
+## 12. Beispiel
+
+### Parent-Task
+**„Nexus Taskflow auf Parent-/Child-Modell umstellen“** — Owner: `iris`
+
+### Mögliche Child-Tasks
+- **Backend-State-Handling anpassen** — Owner: `developer`
+- **Frontend-Board-Spalten und Labels anpassen** — Owner: `developer`
+- **Workflow verifizieren / Regression prüfen** — Owner: `reviewer`
+- **Deploy-/Runtime-Auswirkung prüfen** — Owner: `architekt`
+
+So sieht Bao später nicht nur „Iris arbeitet daran“, sondern konkret:
+
+- welcher Teil erledigt ist
+- welcher Teil noch läuft
+- welcher Teil blockiert ist
+- worauf Iris gerade wartet
+
+---
+
+## 13. Anti-Patterns
+
+Diese Muster sollen vermieden werden:
+
+- Parent-Task auf einen bloßen **Delegated**-Wartestatus schieben
+- Delegation nur im Chat sichtbar machen
+- Child-Tasks ohne klare Ownership anlegen
+- Blocker nur mündlich erwähnen, aber nicht im Board markieren
+- zehn Mikro-Subtasks für einen Mini-Arbeitsschritt erzeugen
+
+---
+
+## 14. Entscheidungsregel für Iris
+
+Wenn Iris unsicher ist, ob sie eine Child-Task anlegen soll, gilt:
+
+**Child-Task anlegen**, wenn mindestens einer der Punkte zutrifft:
+
+- anderer Agent übernimmt echte Arbeit
+- eigener Status muss sichtbar verfolgt werden
+- eigener Blocker ist möglich
+- Bao soll Transparenz über diesen Teil sehen
+
+---
+
+## 15. Technische Leitplanken
+
+- `parentTaskId` verknüpft Child-Tasks mit der Parent-Task
+- `AssignedTo` zeigt den operativen Owner
+- Agentenstatus und Boardstatus dürfen sich ergänzen, aber nicht widersprechen
+- Board-Spalten und API-State-Mapping müssen das Parent-/Child-Modell sauber abbilden
+- UI und Doku müssen dieselbe Sprache sprechen
+
+---
+
+## 16. Merksatz
+
+> **Iris koordiniert die Hauptaufgabe. Agenten erledigen sichtbare Child-Tasks. Das Board zeigt die Wahrheit. OpenClaw führt aus.**

+Fast, disk space efficient package manager:
+
+* **Fast.** Up to 2x faster than the alternatives (see [benchmark](#benchmark)).
+* **Efficient.** Files inside `node_modules` are linked from a single content-addressable storage.
+* **[Great for monorepos](https://pnpm.io/workspaces).**
+* **Strict.** A package can access only dependencies that are specified in its `package.json`.
+* **Deterministic.** Has a lockfile called `pnpm-lock.yaml`.
+* **Works as a Node.js version manager.** See [pnpm env use](https://pnpm.io/cli/env).
+* **Works everywhere.** Supports Windows, Linux, and macOS.
+* **Battle-tested.** Used in production by teams of [all sizes](https://pnpm.io/users) since 2016.
+* [See the full feature comparison with npm and Yarn](https://pnpm.io/feature-comparison).
+
+To quote the [Rush](https://rushjs.io/) team:
+
+> Microsoft uses pnpm in Rush repos with hundreds of projects and hundreds of PRs per day, and we’ve found it to be very fast and reliable.

+## Background
+
+pnpm uses a content-addressable filesystem to store all files from all module directories on a disk.
+When using npm, if you have 100 projects using lodash, you will have 100 copies of lodash on disk.
+With pnpm, lodash will be stored in a content-addressable storage, so:
+
+1. If you depend on different versions of lodash, only the files that differ are added to the store.
+  If lodash has 100 files, and a new version has a change only in one of those files,
+  `pnpm update` will only add 1 new file to the storage.
+1. All the files are saved in a single place on the disk. When packages are installed, their files are linked
+  from that single place consuming no additional disk space. Linking is performed using either hard-links or reflinks (copy-on-write).
+
+As a result, you save gigabytes of space on your disk and you have a lot faster installations!
+If you'd like more details about the unique `node_modules` structure that pnpm creates and
+why it works fine with the Node.js ecosystem, read this small article: [Flat node_modules is not the only way](https://pnpm.io/blog/2020/05/27/flat-node-modules-is-not-the-only-way).
