+# Custom Documentation Deployment Server
+
+Complete guide for setting up and configuring custom deployment servers for mdBook documentation.
+
+## Overview
+
+VAPORA supports multiple custom deployment methods:
+
+- **SSH/SFTP** — Direct file synchronization to remote servers
+- **HTTP** — API-based deployment with REST endpoints
+- **Docker** — Container registry deployment
+- **AWS S3** — Cloud object storage with CloudFront CDN
+- **Google Cloud Storage** — GCS with cache control
+
+## 🔐 Prerequisites
+
+### Repository Secrets Setup
+
+Add these secrets to GitHub repository (**Settings** → **Secrets and variables** → **Actions**):
+
+#### Core Secrets (all methods)
+```
+DOCS_DEPLOY_METHOD        # ssh, sftp, http, docker, s3, gcs
+```
+
+#### SSH/SFTP Method
+```
+DOCS_DEPLOY_HOST          # docs.your-domain.com
+DOCS_DEPLOY_USER          # docs (remote user)
+DOCS_DEPLOY_PATH          # /var/www/vapora-docs
+DOCS_DEPLOY_KEY           # SSH private key (base64 encoded)
+```
+
+#### HTTP Method
+```
+DOCS_DEPLOY_ENDPOINT      # https://deploy.your-domain.com/api/deploy
+DOCS_DEPLOY_TOKEN         # Authentication bearer token
+```
+
+#### AWS S3 Method
+```
+AWS_ACCESS_KEY_ID
+AWS_SECRET_ACCESS_KEY
+AWS_DOCS_BUCKET           # vapora-docs-prod
+AWS_REGION                # us-east-1
+```
+
+#### Google Cloud Storage Method
+```
+GCS_CREDENTIALS_FILE      # Service account JSON (base64 encoded)
+GCS_DOCS_BUCKET           # vapora-docs-prod
+```
+
+#### Docker Registry Method
+```
+DOCKER_REGISTRY           # registry.your-domain.com
+DOCKER_USERNAME
+DOCKER_PASSWORD
+```
+
+---
+
+## 📝 Deployment Script
+
+The deployment script is located at: `.scripts/deploy-docs.sh`
+
+### Script Features
+
+- ✅ Supports 6 deployment methods
+- ✅ Pre-flight validation (connectivity, required files)
+- ✅ Automatic backups (SSH/SFTP)
+- ✅ Post-deployment verification
+- ✅ Detailed logging
+- ✅ Rollback capability (SSH)
+
+### Configuration Files
+
+```
+.scripts/
+├── deploy-docs.sh                (Main deployment script)
+├── .deploy-config.production     (Production config)
+└── .deploy-config.staging        (Staging config)
+```
+
+### Running Locally
+
+```bash
+# Build locally first
+cd docs && mdbook build
+
+# Deploy to production
+bash .scripts/deploy-docs.sh production
+
+# Deploy to staging
+bash .scripts/deploy-docs.sh staging
+
+# View logs
+tail -f /tmp/docs-deploy-*.log
+```
+
+---
+
+## 🔧 SSH/SFTP Deployment Setup
+
+### 1. Create Deployment User on Remote Server
+
+```bash
+# SSH into your server
+ssh user@docs.your-domain.com
+
+# Create docs user
+sudo useradd -m -d /var/www/vapora-docs -s /bin/bash docs
+
+# Set up directory
+sudo mkdir -p /var/www/vapora-docs/backups
+sudo chown -R docs:docs /var/www/vapora-docs
+sudo chmod 755 /var/www/vapora-docs
+```
+
+### 2. Configure SSH Key
+
+```bash
+# On your deployment server
+sudo -u docs mkdir -p /var/www/vapora-docs/.ssh
+sudo -u docs chmod 700 /var/www/vapora-docs/.ssh
+
+# Create authorized_keys
+sudo -u docs touch /var/www/vapora-docs/.ssh/authorized_keys
+sudo -u docs chmod 600 /var/www/vapora-docs/.ssh/authorized_keys
+```
+
+### 3. Add Public Key to Server
+
+```bash
+# Locally, generate key (if needed)
+ssh-keygen -t ed25519 -f ~/.ssh/vapora-docs -N ""
+
+# Add to server's authorized_keys
+cat ~/.ssh/vapora-docs.pub | ssh user@docs.your-domain.com \
+  "sudo -u docs tee -a /var/www/vapora-docs/.ssh/authorized_keys"
+
+# Test connection
+ssh -i ~/.ssh/vapora-docs docs@docs.your-domain.com "ls -la"
+```
+
+### 4. Add to GitHub Secrets
+
+```bash
+# Encode private key (base64)
+cat ~/.ssh/vapora-docs | base64 -w0 | pbcopy
+
+# Paste into GitHub Secrets:
+# Settings → Secrets → New repository secret
+# Name: DOCS_DEPLOY_KEY
+# Value: [paste base64-encoded key]
+```
+
+### 5. Add SSH Configuration Secrets
+
+```
+DOCS_DEPLOY_METHOD    = ssh
+DOCS_DEPLOY_HOST      = docs.your-domain.com
+DOCS_DEPLOY_USER      = docs
+DOCS_DEPLOY_PATH      = /var/www/vapora-docs
+DOCS_DEPLOY_KEY       = [base64-encoded private key]
+```
+
+### 6. Set Up Web Server
+
+```bash
+# On remote server, configure nginx
+sudo tee /etc/nginx/sites-available/vapora-docs > /dev/null << 'EOF'
+server {
+    listen 80;
+    server_name docs.your-domain.com;
+    root /var/www/vapora-docs/docs;
+
+    location / {
+        index index.html;
+        try_files $uri $uri/ /index.html;
+    }
+
+    location ~ \.(js|css|fonts|images)$ {
+        expires 1h;
+        add_header Cache-Control "public, immutable";
+    }
+}
+EOF
+
+# Enable site
+sudo ln -s /etc/nginx/sites-available/vapora-docs \
+  /etc/nginx/sites-enabled/vapora-docs
+
+# Test and reload
+sudo nginx -t && sudo systemctl reload nginx
+```
+
+---
+
+## 🌐 HTTP API Deployment Setup
+
+### 1. Create Deployment Endpoint
+
+Implement an HTTP endpoint that accepts deployments:
+
+```python
+# Example: Flask deployment API
+from flask import Flask, request, jsonify
+import tarfile
+import os
+from pathlib import Path
+
+app = Flask(__name__)
+
+DOCS_PATH = "/var/www/vapora-docs"
+BACKUP_PATH = f"{DOCS_PATH}/backups"
+
+@app.route('/api/deploy', methods=['POST'])
+def deploy():
+    # Verify token
+    token = request.headers.get('Authorization', '').replace('Bearer ', '')
+    if not verify_token(token):
+        return {'error': 'Unauthorized'}, 401
+
+    # Check for archive
+    if 'archive' not in request.files:
+        return {'error': 'No archive provided'}, 400
+
+    archive = request.files['archive']
+
+    # Create backup
+    os.makedirs(BACKUP_PATH, exist_ok=True)
+    backup_name = f"backup_{int(time.time())}"
+    os.rename(f"{DOCS_PATH}/current",
+              f"{BACKUP_PATH}/{backup_name}")
+
+    # Extract archive
+    os.makedirs(f"{DOCS_PATH}/current", exist_ok=True)
+    with tarfile.open(fileobj=archive) as tar:
+        tar.extractall(f"{DOCS_PATH}/current")
+
+    # Update symlink
+    os.symlink(f"{DOCS_PATH}/current", f"{DOCS_PATH}/docs")
+
+    return {'status': 'deployed', 'backup': backup_name}, 200
+
+@app.route('/health', methods=['GET'])
+def health():
+    return {'status': 'healthy'}, 200
+
+def verify_token(token):
+    # Implement your token verification
+    return token == os.getenv('DEPLOY_TOKEN')
+
+if __name__ == '__main__':
+    app.run(host='127.0.0.1', port=5000)
+```
+
+### 2. Configure Nginx Reverse Proxy
+
+```nginx
+upstream deploy_api {
+    server 127.0.0.1:5000;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name deploy.your-domain.com;
+
+    ssl_certificate /etc/letsencrypt/live/deploy.your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/deploy.your-domain.com/privkey.pem;
+
+    # API endpoint
+    location /api/deploy {
+        proxy_pass http://deploy_api;
+        client_max_body_size 100M;
+    }
+
+    # Health check
+    location /health {
+        proxy_pass http://deploy_api;
+    }
+}
+```
+
+### 3. Add GitHub Secrets
+
+```
+DOCS_DEPLOY_METHOD      = http
+DOCS_DEPLOY_ENDPOINT    = https://deploy.your-domain.com/api/deploy
+DOCS_DEPLOY_TOKEN       = your-secure-token
+```
+
+---
+
+## ☁️ AWS S3 Deployment Setup
+
+### 1. Create S3 Bucket and IAM User
+
+```bash
+# Create bucket
+aws s3 mb s3://vapora-docs-prod --region us-east-1
+
+# Create IAM user
+aws iam create-user --user-name vapora-docs-deployer
+
+# Create access key
+aws iam create-access-key --user-name vapora-docs-deployer
+
+# Create policy
+cat > /tmp/s3-policy.json << 'EOF'
+{
+  "Version": "2012-10-17",
+  "Statement": [
+    {
+      "Effect": "Allow",
+      "Action": [
+        "s3:GetObject",
+        "s3:PutObject",
+        "s3:DeleteObject",
+        "s3:ListBucket"
+      ],
+      "Resource": [
+        "arn:aws:s3:::vapora-docs-prod",
+        "arn:aws:s3:::vapora-docs-prod/*"
+      ]
+    }
+  ]
+}
+EOF
+
+# Attach policy
+aws iam put-user-policy \
+  --user-name vapora-docs-deployer \
+  --policy-name S3Access \
+  --policy-document file:///tmp/s3-policy.json
+```
+
+### 2. Configure CloudFront (Optional)
+
+```bash
+# Create distribution
+aws cloudfront create-distribution \
+  --origin-domain-name vapora-docs-prod.s3.amazonaws.com \
+  --default-root-object index.html
+```
+
+### 3. Add GitHub Secrets
+
+```
+DOCS_DEPLOY_METHOD      = s3
+AWS_ACCESS_KEY_ID       = AKIAIOSFODNN7EXAMPLE
+AWS_SECRET_ACCESS_KEY   = wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
+AWS_DOCS_BUCKET         = vapora-docs-prod
+AWS_REGION              = us-east-1
+```
+
+---
+
+## 🐳 Docker Registry Deployment Setup
+
+### 1. Create Docker Registry
+
+```bash
+# Using Docker Registry (self-hosted)
+docker run -d \
+  -p 5000:5000 \
+  --restart always \
+  --name registry \
+  -e REGISTRY_STORAGE_DELETE_ENABLED=true \
+  registry:2
+
+# Or use managed: AWS ECR, Docker Hub, etc.
+```
+
+### 2. Configure Registry Authentication
+
+```bash
+# Create credentials
+echo "username:$(openssl passwd -crypt password)" > /auth/htpasswd
+
+# Docker login
+docker login registry.your-domain.com \
+  -u username -p password
+```
+
+### 3. Add GitHub Secrets
+
+```
+DOCS_DEPLOY_METHOD      = docker
+DOCKER_REGISTRY         = registry.your-domain.com
+DOCKER_USERNAME         = username
+DOCKER_PASSWORD         = password
+```
+
+---
+
+## 🔔 Webhooks & Notifications
+
+### Slack Notification
+
+Add webhook URL to secrets:
+
+```
+NOTIFICATION_WEBHOOK = https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXX
+```
+
+Workflow sends JSON payload:
+
+```json
+{
+  "status": "success",
+  "environment": "production",
+  "commit": "abc123...",
+  "branch": "main",
+  "timestamp": "2026-01-12T14:30:00Z",
+  "run_url": "https://github.com/vapora-platform/vapora/actions/runs/123"
+}
+```
+
+### Custom Webhook Handler
+
+```python
+@app.route('/webhook/deployment', methods=['POST'])
+def deployment_webhook():
+    data = request.json
+
+    if data['status'] == 'success':
+        send_slack_message(f"✅ Docs deployed: {data['commit']}")
+    else:
+        send_slack_message(f"❌ Deployment failed: {data['commit']}")
+
+    return {'ok': True}
+```
+
+---
+
+## 🔄 Deployment Workflow

+
+---
+
+## 🆘 Troubleshooting
+
+### SSH Deployment Fails
+
+**Error**: `Permission denied (publickey)`
+
+**Fix**:
+```bash
+# Verify key is in authorized_keys
+cat ~/.ssh/vapora-docs.pub | ssh user@server \
+  "sudo -u docs cat >> /var/www/vapora-docs/.ssh/authorized_keys"
+
+# Test connection
+ssh -i ~/.ssh/vapora-docs -v docs@server.com
+```
+
+### HTTP Deployment Fails
+
+**Error**: `HTTP 401 Unauthorized`
+
+**Fix**:
+- Verify token in GitHub Secrets matches server
+- Check HTTPS certificate validity
+- Verify endpoint is reachable
+
+```bash
+curl -H "Authorization: Bearer $TOKEN" https://deploy.server.com/health
+```
+
+### S3 Deployment Fails
+
+**Error**: `NoSuchBucket`
+
+**Fix**:
+- Verify bucket name in secrets
+- Check IAM policy allows the action
+- Verify AWS credentials
+
+```bash
+aws s3 ls s3://vapora-docs-prod/
+```
+
+### Docker Deployment Fails
+
+**Error**: `unauthorized: authentication required`
+
+**Fix**:
+- Verify credentials in secrets
+- Test Docker login locally
+
+```bash
+docker login registry.your-domain.com
+```

+
+## 🚀 Quick Start (5 Minutes)
+
+### Fastest Way: GitHub Pages
+
+```bash
+# 1. Repository → Settings → Pages
+# 2. Select: GitHub Actions
+# 3. Save
+# 4. Push any docs/ change
+# Done!
+```
+
+### Fastest Way: SSH to Existing Server
+
+```bash
+# Generate SSH key
+ssh-keygen -t ed25519 -f ~/.ssh/vapora-docs -N ""
+
+# Add to server
+ssh-copy-id -i ~/.ssh/vapora-docs user@your-server.com
+
+# Add GitHub secrets (Settings → Secrets → Actions)
+# DOCS_DEPLOY_METHOD = ssh
+# DOCS_DEPLOY_HOST = your-server.com
+# DOCS_DEPLOY_USER = user
+# DOCS_DEPLOY_PATH = /var/www/docs
+# DOCS_DEPLOY_KEY = [base64: cat ~/.ssh/vapora-docs | base64]
+```
+
+---
+
+## 📦 Deployment Methods Comparison
+
+| Method | Setup | Speed | Cost | Best For |
+|--------|-------|-------|------|----------|
+| **GitHub Pages** | 2 min | Fast | Free | Public docs |
+| **SSH** | 10 min | Medium | Server | Private docs, full control |
+| **S3 + CloudFront** | 5 min | Fast | $1-5/mo | Global scale |
+| **Docker** | 15 min | Medium | Varies | Container orchestration |
+| **HTTP API** | 20 min | Medium | Server | Custom deployment logic |
+| **GCS** | 5 min | Fast | $0.02/GB | Google Cloud users |
+
+---
+
+## 🔐 Security
+
+### SSH Key Management
+
+```bash
+# Generate key securely
+ssh-keygen -t ed25519 -f ~/.ssh/vapora-docs -N "strong-passphrase"
+
+# Encode for GitHub (base64)
+cat ~/.ssh/vapora-docs | base64 -w0 > /tmp/key.b64
+
+# Add to GitHub Secrets (do NOT commit key anywhere)
+# Settings → Secrets and variables → Actions → DOCS_DEPLOY_KEY
+```
+
+### Principle of Least Privilege
+
+```bash
+# Create restricted deployment user
+sudo useradd -m -d /var/www/docs -s /bin/false docs
+
+# Grant only necessary permissions
+sudo chmod 755 /var/www/docs
+sudo chown docs:www-data /var/www/docs
+
+# SSH key permissions (on server)
+sudo -u docs chmod 700 ~/.ssh
+sudo -u docs chmod 600 ~/.ssh/authorized_keys
+```
+
+### Secrets Rotation
+
+**Recommended**: Rotate deployment secrets quarterly
+
+```bash
+# Generate new key
+ssh-keygen -t ed25519 -f ~/.ssh/vapora-docs-new -N ""
+
+# Update on server
+ssh-copy-id -i ~/.ssh/vapora-docs-new user@your-server.com
+
+# Update GitHub secret
+# Settings → Secrets → DOCS_DEPLOY_KEY → Update
+
+# Remove old key from server
+ssh user@your-server.com
+sudo -u docs nano ~/.ssh/authorized_keys
+# Delete old key, save
+```

+## 🆘 Common Issues
+
+### Issue: "Cannot connect to server"
+
+**Cause**: SSH connectivity problem
+
+**Fix**:
+```bash
+# Test SSH directly
+ssh -vvv -i ~/.ssh/vapora-docs user@your-server.com
+
+# Check GitHub secret encoding
+cat ~/.ssh/vapora-docs | base64 | wc -c
+# Should be long string
+
+# Verify server firewall
+ssh -p 22 user@your-server.com echo "ok"
+```
+
+### Issue: "rsync: command not found"
+
+**Cause**: rsync not installed on server
+
+**Fix**:
+```bash
+ssh user@your-server.com
+sudo apt-get install rsync  # Debian/Ubuntu
+# OR
+sudo yum install rsync      # RedHat/CentOS
+```
+
+### Issue: "Permission denied" on server
+
+**Cause**: docs user doesn't have write permission
+
+**Fix**:
+```bash
+ssh user@your-server.com
+sudo chown -R docs:docs /var/www/docs
+sudo chmod -R 755 /var/www/docs
+```
+
+### Issue: Documentation not appearing on site
+
+**Cause**: nginx not configured or files not updated
+
+**Fix**:
+```bash
+# Check nginx config
+sudo nginx -T | grep root
+
+# Verify files are there
+sudo ls -la /var/www/docs/index.html
+
+# Reload nginx
+sudo systemctl reload nginx
+
+# Check nginx logs
+sudo tail -f /var/log/nginx/error.log
+```
+
+### Issue: GitHub Actions fails with "No secrets found"
+
+**Cause**: Secrets not configured
+
+**Fix**:
+```bash
+# Settings → Secrets and variables → Actions
+# Verify all required secrets are present
+# Check spelling matches deployment script
+```
+
+---
+
+## 📈 Performance Monitoring
+
+### Workflow Performance
+
+Track metrics after each deployment:
+
+```
+Build Time:     ~2-3 seconds
+Deploy Time:    ~10-30 seconds (method-dependent)
+Total Time:     ~1-2 minutes
+```
+
+### Site Performance
+
+Monitor after deployment:
+
+```bash
+# Page load time
+curl -w "Time: %{time_total}s\n" https://docs.your-domain.com/
+
+# Lighthouse audit
+lighthouse https://docs.your-domain.com
+
+# Cache headers
+curl -I https://docs.your-domain.com/ | grep Cache-Control
+```
+
+### Artifact Management
+
+Default: 30 days retention
+
+```bash
+# View artifacts
+GitHub → Actions → Workflow run → Artifacts
+
+# Manual cleanup
+# (GitHub handles auto-cleanup after 30 days)
+```
+
+---
+
+## 🔄 Disaster Recovery
+
+### Rollback Procedure (SSH)
+
+```bash
+# SSH into server
+ssh -i ~/.ssh/vapora-docs user@your-server.com
+
+# List backups
+ls -la /var/www/docs/backups/
+
+# Restore from backup
+sudo -u docs mv /var/www/docs/current /var/www/docs/current-failed
+sudo -u docs mv /var/www/docs/backups/backup_20260112_143000 \
+                /var/www/docs/current
+sudo -u docs ln -sfT /var/www/docs/current /var/www/docs/docs
+```
+
+### Manual Deployment (No GitHub Actions)
+
+```bash
+# Build locally
+cd docs
+mdbook build
+
+# Deploy using script
+DOCS_DEPLOY_METHOD=ssh \
+DOCS_DEPLOY_HOST=your-server.com \
+DOCS_DEPLOY_USER=docs \
+DOCS_DEPLOY_PATH=/var/www/docs \
+bash .scripts/deploy-docs.sh production

+
+---
+
+## 🚀 Deployment Options
+
+### Option 1: GitHub Pages (GitHub.com)
+
+**Best for**: Public documentation, free hosting
+
+**Setup**:
+
+1. Go to repository **Settings** → **Pages**
+2. Under **Build and deployment**:
+   - Source: **GitHub Actions**
+   - (Leave branch selection empty)
+3. Save settings
+
+**Deployment Process**:
+
+```bash
+# Make documentation changes
+git add docs/
+git commit -m "docs: update content"
+git push origin main
+
+# Automatic workflow triggers:
+# 1. mdBook Build & Deploy starts
+# 2. Builds documentation
+# 3. Uploads to GitHub Pages
+# 4. Available at: https://username.github.io/repo-name/
+```
+
+**Verify Deployment**:
+
+1. Go to **Settings** → **Pages**
+2. Look for **Your site is live at: https://...**
+3. Click link to verify
+4. Hard refresh if needed (Ctrl+Shift+R)
+
+**Custom Domain** (optional):
+
+1. Settings → Pages → **Custom domain**
+2. Enter domain: `docs.vapora.io`
+3. Add DNS record (CNAME):
+   ```
+   docs.vapora.io CNAME username.github.io
+   ```
+4. Wait 5-10 minutes for DNS propagation
+
+---
+
+### Option 2: Custom Server / Self-Hosted
+
+**Best for**: Private documentation, custom deployment
+
+**Setup**:
+
+1. Create deployment script (e.g., `deploy.sh`):
+
+```bash
+#!/bin/bash
+# .scripts/deploy-docs.sh
+
+cd docs
+mdbook build
+
+# Copy to web server
+scp -r book/ user@server:/var/www/docs/
+
+echo "Documentation deployed!"
+```
+
+2. Add to workflow `.github/workflows/mdbook-publish.yml`:
+
+```yaml
+- name: Deploy to custom server
+  run: bash .scripts/deploy-docs.sh
+  env:
+    DEPLOY_HOST: ${{ secrets.DEPLOY_HOST }}
+    DEPLOY_USER: ${{ secrets.DEPLOY_USER }}
+    DEPLOY_KEY: ${{ secrets.DEPLOY_KEY }}
+```
+
+3. Add secrets in **Settings** → **Secrets and variables** → **Actions**
+
+---
+
+### Option 3: Docker & Container Registry
+
+**Best for**: Containerized deployment
+
+**Dockerfile**:
+
+```dockerfile
+FROM nginx:alpine
+
+# Install mdBook
+RUN apk add --no-cache curl && \
+    curl -L https://github.com/rust-lang/mdBook/releases/download/v0.4.36/mdbook-v0.4.36-x86_64-unknown-linux-gnu.tar.gz | tar xz -C /usr/local/bin
+
+# Copy docs
+COPY docs /docs
+
+# Build
+WORKDIR /docs
+RUN mdbook build
+
+# Serve with nginx
+FROM nginx:alpine
+COPY --from=0 /docs/book /usr/share/nginx/html
+
+EXPOSE 80
+CMD ["nginx", "-g", "daemon off;"]
+```
+
+**Build & Push**:
+
+```bash
+docker build -t myrepo/vapora-docs:latest .
+docker push myrepo/vapora-docs:latest
+```
+
+---
+
+### Option 4: CDN & Cloud Storage
+
+**Best for**: High availability, global distribution
+
+#### AWS S3 + CloudFront
+
+```yaml
+- name: Deploy to S3
+  run: |
+    aws s3 sync docs/book s3://my-docs-bucket/docs \
+      --delete --region us-east-1
+  env:
+    AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
+    AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
+```
+
+#### Google Cloud Storage
+
+```yaml
+- name: Deploy to GCS
+  run: |
+    gsutil -m rsync -d -r docs/book gs://my-docs-bucket/docs
+  env:
+    GCLOUD_SERVICE_KEY: ${{ secrets.GCLOUD_SERVICE_KEY }}
+```
+
+---
+
+## 🔄 Automated Deployment Workflow
+
+### Push to Main
+
+```
+Your Changes
+    ↓
+git push origin main
+    ↓
+GitHub Triggers Workflows
+    ↓
+mdBook Build & Deploy Starts
+    ├─ Checkout code
+    ├─ Install mdBook
+    ├─ Build documentation
+    ├─ Validate quality
+    ├─ Upload artifact
+    └─ Deploy to Pages (or custom)
+    ↓
+Documentation Live
+```
+
+### Manual Artifact Deployment
+
+For non-automated deployments:
+
+1. Trigger workflow manually (if configured):
+   ```
+   Actions → mdBook Build & Deploy → Run workflow
+   ```
+
+2. Wait for completion
+
+3. Download artifact:
+   ```
+   Click run → Artifacts → mdbook-site-{sha}
+   ```
+
+4. Extract and deploy:
+   ```bash
+   unzip mdbook-site-abc123.zip
+   scp -r book/* user@server:/var/www/docs/
+   ```
+
+---
+
+## 🔐 Security Considerations
+
+### Secrets Management
+
+Never commit API keys or credentials. Use GitHub Secrets:
+
+```bash
+# Add secret
+Settings → Secrets and variables → Actions → New repository secret
+
+Name: DEPLOY_TOKEN
+Value: your-token-here
+```
+
+Reference in workflow:
+```yaml
+env:
+  DEPLOY_TOKEN: ${{ secrets.DEPLOY_TOKEN }}
+```
+
+### Branch Protection
+
+Prevent direct pushes to main:
+
+```
+Settings → Branches → Add rule
+├─ Branch name pattern: main
+├─ Require pull request reviews: 1
+├─ Dismiss stale PR approvals: ✓
+├─ Require status checks to pass: ✓
+└─ Include administrators: ✓
+```
+
+### Access Control
+
+Limit who can deploy:
+
+1. Settings → Environments → Create new
+2. Name: `docs` or `production`
+3. Under "Required reviewers": Add team/users
+4. Deployments require approval
+
+---
+
+## 📊 Monitoring Deployment
+
+### GitHub Actions Dashboard
+
+**View all deployments**:
+```
+Actions → All workflows → mdBook Build & Deploy
+```
+
+**Check individual run**:
+- Status (✅ Success, ❌ Failed)
+- Execution time
+- Log details
+- Artifact details
+
+### Health Checks
+
+Monitor deployed documentation:
+
+```bash
+# Check if site is live
+curl -I https://docs.vapora.io
+
+# Expected: 200 OK
+# Check content
+curl https://docs.vapora.io | grep "VAPORA"
+```
+
+### Performance Monitoring
+
+1. **Lighthouse** (local):
+   ```bash
+   lighthouse https://docs.vapora.io
+   ```
+
+2. **GitHub Pages Analytics** (if enabled)
+
+3. **Custom monitoring**:
+   - Check response time
+   - Monitor 404 errors
+   - Track page views
+
+---
+
+## 🔍 Troubleshooting Deployment
+
+### Issue: GitHub Pages shows 404
+
+**Cause**: Pages not configured or build failed
+
+**Fix**:
+```
+1. Settings → Pages → Verify source is "GitHub Actions"
+2. Check Actions tab for build failures
+3. Hard refresh browser (Ctrl+Shift+R)
+4. Wait 1-2 minutes if just deployed
+```
+
+### Issue: Custom domain not resolving
+
+**Cause**: DNS not propagated or CNAME incorrect
+
+**Fix**:
+```bash
+# Check DNS resolution
+nslookup docs.vapora.io
+
+# Should show correct IP
+# Wait 5-10 minutes if just created
+# Check CNAME record:
+dig docs.vapora.io CNAME
+```
+
+### Issue: Old documentation still showing
+
+**Cause**: Browser cache or CDN cache
+
+**Fix**:
+```bash
+# Hard refresh in browser
+Ctrl+Shift+R (Windows/Linux)
+Cmd+Shift+R (Mac)
+
+# Or clear entire browser cache
+# Settings → Privacy → Clear browsing data
+
+# For CDN: Purge cache
+AWS CloudFront: Go to Distribution → Invalidate
+```
+
+### Issue: Deployment workflow fails
+
+**Check logs**:
+
+1. Go to Actions → Failed run
+2. Click job name
+3. Expand failed step
+4. Look for error message
+
+**Common errors**:
+
+| Error | Fix |
+|-------|-----|
+| `mdbook: command not found` | First run takes time to install |
+| `Cannot find file` | Check SUMMARY.md relative paths |
+| `Permission denied` | Check deployment secrets/keys |
+| `Network error` | Check firewall/connectivity |
+
+---

+# GitHub Actions Setup for mdBook Documentation
+
+## Overview
+
+Three automated workflows have been configured to manage mdBook documentation:
+
+1. **mdBook Build & Deploy** — Builds documentation and validates quality
+2. **mdBook Publish & Sync** — Handles downstream deployment notifications
+3. **Documentation Lint & Validation** — Validates markdown and configuration
+
+## 📋 Workflows
+
+### 1. mdBook Build & Deploy
+
+**File**: `.github/workflows/mdbook-build-deploy.yml`
+
+**Triggers**:
+- Push to `main` branch when `docs/**` or workflow file changes
+- Pull requests to `main` when `docs/**` changes
+
+**Jobs**:
+
+#### Build Job
+- ✅ Installs mdBook (`cargo install mdbook`)
+- ✅ Builds documentation (`mdbook build`)
+- ✅ Validates HTML output (checks for essential files)
+- ✅ Counts generated pages
+- ✅ Uploads artifact (retained 30 days)
+- ✅ Provides build summary
+
+**Outputs**:
+```
+docs/book/
+├── index.html
+├── print.html
+├── css/
+├── js/
+├── fonts/
+└── ... (all mdBook assets)
+```
+
+**Artifact**: `mdbook-site-{commit-sha}`
+
+#### Quality Check Job
+- ✅ Verifies content (VAPORA in index.html)
+- ✅ Checks for empty files
+- ✅ Validates CSS files
+- ✅ Generates file statistics
+- ✅ Reports total size and file counts
+
+#### GitHub Pages Deployment Job
+- ✅ Runs on push to `main` only (skips PRs)
+- ✅ Sets up GitHub Pages environment
+- ✅ Uploads artifact to Pages
+- ✅ Deploys to GitHub Pages (if configured)
+- ✅ Continues on error (handles non-GitHub deployments)
+
+**Key Features**:
+- Concurrent runs on same ref are cancelled
+- Artifact retained for 30 days
+- Supports GitHub Pages or custom deployments
+- Detailed step summaries in workflow run
+
+### 2. mdBook Publish & Sync
+
+**File**: `.github/workflows/mdbook-publish.yml`
+
+**Triggers**:
+- Runs after `mdBook Build & Deploy` workflow completes successfully
+- Only on `main` branch
+
+**Jobs**:
+
+#### Download & Publish Job
+- ✅ Finds mdBook build artifact
+- ✅ Creates deployment record
+- ✅ Provides deployment summary
+
+**Use Cases**:
+- Trigger custom deployment scripts
+- Send notifications to deployment services
+- Update documentation registry
+- Sync to content CDN
+
+### 3. Documentation Lint & Validation
+
+**File**: `.github/workflows/docs-lint.yml`
+
+**Triggers**:
+- Push to `main` when `docs/**` changes
+- All pull requests when `docs/**` changes
+
+**Jobs**:
+
+#### Markdown Lint Job
+- ✅ Installs markdownlint-cli
+- ✅ Validates markdown formatting
+- ✅ Reports formatting issues
+- ✅ Non-blocking (doesn't fail build)
+
+**Checked Rules**:

+## 🔧 Configuration
+
+### Enable GitHub Pages Deployment
+
+**For GitHub.com repositories**:
+
+1. Go to repository **Settings** → **Pages**
+2. Select:
+   - **Source**: GitHub Actions
+   - **Branch**: main
+3. Optional: Add custom domain
+
+**Workflow will then**:
+- Auto-deploy to GitHub Pages on every push to `main`
+- Available at: `https://username.github.io/repo-name`
+- Or custom domain if configured
+
+### Custom Deployment (Non-GitHub)
+
+For repositories on custom servers:
+
+1. GitHub Pages deployment will be skipped (non-blocking)
+2. Artifact will be uploaded and retained 30 days
+3. Download from workflow run → Artifacts section
+4. Use `mdbook-publish.yml` to trigger custom deployment
+
+**To add custom deployment script**:
+
+Add to `.github/workflows/mdbook-publish.yml`:
+
+```yaml
+- name: Deploy to custom server
+  run: |
+    # Add your deployment script here
+    curl -X POST https://your-docs-server/deploy \
+      -H "Authorization: Bearer ${{ secrets.DEPLOY_TOKEN }}" \
+      -F "artifact=@docs/book.zip"
+```
+
+### Access Control
+
+**Permissions configured**:
+```yaml
+permissions:
+  contents: read        # Read repository contents
+  pages: write          # Write to GitHub Pages
+  id-token: write       # For OIDC token
+  deployments: write    # Write deployment records
+```

+
+## 🚨 Troubleshooting
+
+### Build Fails: "mdBook not found"
+
+**Fix**: mdBook is installed via `cargo install`
+- Requires Rust toolchain
+- First run takes ~60 seconds
+- Subsequent runs cached
+
+### Build Fails: "SUMMARY.md not found"
+
+**Fix**: Ensure `docs/src/SUMMARY.md` exists
+
+```bash
+ls -la docs/src/SUMMARY.md
+```
+
+### Build Fails: "Broken link in SUMMARY.md"
+
+**Error message**: `Cannot find file '../section/file.md'`
+
+**Fix**:
+1. Verify file exists
+2. Check relative path spelling
+3. Use `../` for parent directory
+
+### GitHub Pages shows 404
+
+**Issue**: Site deployed but pages not accessible
+
+**Fix**:
+1. Go to **Settings** → **Pages**
+2. Verify **Source** is set to **GitHub Actions**
+3. Wait 1-2 minutes for deployment
+4. Hard refresh browser (Ctrl+Shift+R)
+
+### Artifact Not Uploaded
+
+**Issue**: Workflow completed but no artifact
+
+**Fix**:
+1. Check build job output for errors
+2. Verify `docs/book/` directory exists
+3. Check artifact upload step logs

+
+## 📝 Content Guidelines
+
+### File Naming
+- Root markdown: **UPPERCASE** (README.md)
+- Content markdown: **lowercase** (setup-guide.md)
+- Multi-word: **kebab-case** (setup-guide.md)
+
+### Markdown Standards
+1. **Code Blocks**: Language specified (bash, rust, toml)
+2. **Lists**: Blank line before and after
+3. **Headings**: Proper hierarchy (h2 → h3 → h4)
+4. **Links**: Relative paths only (`../section/file.md`)
+
+### Internal Links Pattern
+
+```markdown
+# Correct (relative paths)
+- [Setup Guide](../setup/setup-guide.md)
+- [ADR 0001](../adrs/0001-cargo-workspace.md)
+
+# Incorrect (absolute or wrong format)
+- [Setup Guide](/docs/setup/setup-guide.md)
+- [ADR 0001](setup-guide.md)
+```
+
+## 🔧 Maintenance
+
+### Adding New Documentation
+
+1. Create markdown file in appropriate subdirectory
+2. Add entry to `docs/src/SUMMARY.md` in correct section
+3. Use relative path: `../section/filename.md`
+4. Run `mdbook build` to generate updated site
+
+Example:
+```markdown
+# In docs/src/SUMMARY.md
+## Tutorials
+- [My New Tutorial](../tutorials/my-tutorial.md)
+```
+
+### Updating Existing Documentation
+
+1. Edit markdown file directly
+2. mdBook automatically picks up changes
+3. Run `mdbook serve` to preview locally
+4. Run `mdbook build` to generate static site
+
+### Fixing Broken Links
+
+mdBook will fail to build if referenced files don't exist. Check error output:
+
+```
+Error: Cannot find file '../nonexistent/file.md'
+```
+
+Verify the file exists and update the link path.
+
+## 📦 Deployment
+
+### Local Preview
+```bash
+mdbook serve
+# Open http://localhost:3000
+```
+
+### GitHub Pages
+```bash
+mdbook build
+git add docs/book/
+git commit -m "docs: update mdBook"
+git push origin main
+```
+
+Configure repository:
+- Settings → Pages
+- Source: `main` branch
+- Path: `docs/book/`
+- Custom domain: `docs.vapora.io` (optional)
+
+### Docker (CI/CD)
+```dockerfile
+FROM rust:latest
+RUN cargo install mdbook
+
+WORKDIR /docs
+COPY . .
+RUN mdbook build
+
+# Output: /docs/book/
+```
+
+### GitHub Actions
+Add workflow file `.github/workflows/docs.yml`:
+
+```yaml
+name: Documentation Build
+
+on:
+  push:
+    paths: ['docs/**']
+    branches: [main]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: peaceiris/actions-mdbook@v4
+      - run: mdbook build
+      - uses: peaceiris/actions-gh-pages@v3
+        with:
+          github_token: ${{ secrets.GITHUB_TOKEN }}
+          publish_dir: ./docs/book
+```
+
+## 🐛 Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| **Broken links in built site** | Use relative paths: `../file.md` not `/file.md` |
+| **Search not working** | Rebuild with `mdbook build` |
+| **Build fails silently** | Run `mdbook build` with `-v` flag for verbose output |
+| **Theme not applying** | Remove `docs/book/` and rebuild |
+| **Port 3000 in use** | Change port: `mdbook serve --port 3001` |
+| **Missing file error** | Check file exists and update SUMMARY.md path |
+
+## ✅ Verification
+
+**Confirm successful setup:**
+
+```bash
+cd /Users/Akasha/Development/vapora/docs
+
+# Build test
+mdbook build
+# Output: book/ directory created with 7.4 MB of files
+
+# Check structure
+ls -la book/index.html     # Should exist
+ls -la src/SUMMARY.md      # Should exist
+ls -la theme/vapora-custom.css  # Should exist
+
+# Serve test
+mdbook serve &
+# Should output: Serving on http://0.0.0.0:3000

+
+### Building the Documentation
+
+**Install mdBook (if not already installed):**
 
 ```bash
+cargo install mdbook
+```
+
+**Build the static site:**
+
+```bash
+cd docs
 mdbook build
+```
+
+Output will be in `docs/book/` directory.
+
+**Serve locally for development:**
+
+```bash
+cd docs
 mdbook serve
 ```
 
+Then open `http://localhost:3000` in your browser. Changes to markdown files will automatically rebuild.
+
+### Documentation Guidelines
+
+#### File Naming
+- **Root markdown**: UPPERCASE (README.md, CHANGELOG.md)
+- **Content markdown**: lowercase (getting-started.md, setup-guide.md)
+- **Multi-word files**: kebab-case (setup-guide.md, disaster-recovery.md)
+
+#### Structure Requirements
+- Each subdirectory **must** have a README.md
+- Use relative paths for internal links: `[link](../other-file.md)`
+- Add proper heading hierarchy: Start with h2 (##) in content files
+
+#### Markdown Compliance (markdownlint)
+1. **Code Blocks (MD031, MD040)**
+   - Add blank line before and after fenced code blocks
+   - Always specify language: \`\`\`bash, \`\`\`rust, \`\`\`toml
+   - Use \`\`\`text for output/logs
+
+2. **Lists (MD032)**
+   - Add blank line before and after lists
+
+3. **Headings (MD022, MD001, MD026, MD024)**
+   - Add blank line before and after headings
+   - Heading levels increment by one
+   - No trailing punctuation
+   - No duplicate heading names
+
+### mdBook Configuration (book.toml)
+
+Key settings:
+
+```toml
+[book]
+title = "VAPORA Platform Documentation"
+src = "src"                    # Where mdBook reads SUMMARY.md
+build-dir = "book"             # Where output is generated
+
+[output.html]
+theme = "theme"                # Path to custom theme
+default-theme = "light"
+edit-url-template = "https://github.com/.../edit/main/docs/{path}"
+```
+
+### Custom Theme
+
+**Location**: `docs/theme/`
+
+- `index.hbs` — HTML template
+- `vapora-custom.css` — Custom styling with VAPORA branding
+
+Features:
+- Professional blue/violet color scheme
+- Responsive design (mobile-friendly)
+- Dark mode support
+- Custom syntax highlighting
+- Print-friendly styles
+
+### Content Organization
+
+The `src/SUMMARY.md` file automatically indexes all documentation:
+
+```
+# VAPORA Documentation
+
+## [Introduction](../README.md)
+
+## Getting Started
+- [Quick Start](../getting-started.md)
+- [Quickstart Guide](../quickstart.md)
+
+## Setup & Deployment
+- [Setup Overview](../setup/README.md)
+- [Setup Guide](../setup/setup-guide.md)
+...
+```
+
+**No manual updates needed** — SUMMARY.md structure remains constant as new docs are added to existing sections.
+
+### Deployment
+
+**GitHub Pages:**
+
+```bash
+# Build the book
+mdbook build
+
+# Commit and push
+git add docs/book/
+git commit -m "chore: update documentation"
+git push origin main
+```
+
+Configure GitHub repository settings:
+- Source: `main` branch
+- Path: `docs/book/`
+- Custom domain: docs.vapora.io (optional)
+
+**Docker (for CI/CD):**
+
+```dockerfile
+FROM rust:latest
+RUN cargo install mdbook
+
+WORKDIR /docs
+COPY . .
+RUN mdbook build
+
+# Output in /docs/book/
+```
+
+### Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Links broken in mdBook | Use relative paths: `../file.md` not `file.md` |
+| Theme not applying | Ensure `theme/` directory exists, run `mdbook build --no-create-missing` |
+| Search not working | Rebuild with `mdbook build` |
+| Build fails | Check for invalid TOML in `book.toml` |
+
+### Quality Assurance
+
+**Before committing documentation:**
+
+```bash
+# Lint markdown
+markdownlint docs/**/*.md
+
+# Build locally
+cd docs && mdbook build
+
+# Verify structure
+cd docs && mdbook serve
+# Open http://localhost:3000 and verify navigation
+```
+
+### CI/CD Integration
+
+Add to `.github/workflows/docs.yml`:
+
+```yaml
+name: Documentation
+
+on:
+  push:
+    paths:
+      - 'docs/**'
+    branches: [main]
+
+jobs:
+  build:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - uses: peaceiris/actions-mdbook@v4
+      - run: cd docs && mdbook build
+      - uses: peaceiris/actions-gh-pages@v3
+        with:
+          github_token: ${{ secrets.GITHUB_TOKEN }}
+          publish_dir: ./docs/book
+```
+
+---
+
+## Content Standards
+
 Ensure all documents follow:
 - Lowercase filenames (except README.md)
 - Kebab-case for multi-word files
 - Each subdirectory has README.md
+- Proper heading hierarchy
+- Clear, concise language
+- Code examples when applicable
+- Cross-references to related docs

+<ol>
+<li><strong>Separation of Concerns</strong>: Each crate owns a distinct architectural layer (backend API, agents, routing, knowledge graph, etc.)</li>
+<li><strong>Independent Testing</strong>: 218+ tests can run in parallel across crates without cross-dependencies</li>
+<li><strong>Code Reusability</strong>: Common utilities (<code>vapora-shared</code>) used by all crates without circular dependencies</li>
+<li><strong>Team Parallelization</strong>: Multiple teams can develop on different crates simultaneously</li>
+<li><strong>Dependency Clarity</strong>: Explicit <code>Cargo.toml</code> dependencies prevent accidental coupling</li>
+<li><strong>Version Management</strong>: Centralized in root <code>Cargo.toml</code> via workspace dependencies prevents version skew</li>

+<h3 id="-monolithic-single-crate"><a class="header" href="#-monolithic-single-crate">❌ Monolithic Single Crate</a></h3>
+<ul>
+<li>All code in <code>/src/</code> directory</li>
+<li><strong>Pros</strong>: Simpler build, familiar structure</li>
+<li><strong>Cons</strong>: Tight coupling, slow compilation, testing all-or-nothing, hard to parallelize development</li>
+</ul>
+<h3 id="-multi-repository"><a class="header" href="#-multi-repository">❌ Multi-Repository</a></h3>
+<ul>
+<li>Separate Git repos for each component</li>

+<li><strong>Cons</strong>: Complex synchronization, dependency management nightmare, monorepo benefits lost (atomic commits)</li>
+</ul>

+<h2 id="trade-offs"><a class="header" href="#trade-offs">Trade-offs</a></h2>
+<p><strong>Pros</strong>:</p>
+<ul>
+<li>✅ Clear architectural boundaries prevent accidental coupling</li>
+<li>✅ Parallel compilation and testing (cargo builds independent crates concurrently)</li>
+<li>✅ 218+ tests distributed across crates, faster feedback</li>
+<li>✅ Atomic commits across multiple components</li>
+<li>✅ Single CI/CD pipeline, shared version management</li>
+<li>✅ Easy debugging: each crate is independently debuggable</li>
+</ul>
+<p><strong>Cons</strong>:</p>
+<ul>
+<li>⚠️ Workspace compilation overhead: must compile all dependencies even if using one crate</li>
+<li>⚠️ Slightly steeper learning curve for developers new to workspaces</li>
+<li>⚠️ Publishing to crates.io requires publishing each crate individually (not a concern for internal project)</li>

+# ADR-001: Cargo Workspace con 13 Crates Especializados
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: VAPORA Architecture Team
+**Technical Story**: Determining optimal project structure for multi-agent orchestration platform
+
+---
+
+## Decision
+
+Adoptar un **Cargo workspace monorepo con 13 crates especializados** en lugar de un monolito único o multi-repositorio.
+
+```text
+crates/
+├── vapora-shared/           # Core models, types, errors
+├── vapora-backend/          # REST API (40+ endpoints)
+├── vapora-agents/           # Agent orchestration + learning
+├── vapora-llm-router/       # Multi-provider LLM routing
+├── vapora-swarm/            # Swarm coordination + metrics
+├── vapora-knowledge-graph/  # Temporal KG + learning curves
+├── vapora-frontend/         # Leptos WASM UI
+├── vapora-mcp-server/       # MCP protocol gateway
+├── vapora-tracking/         # Task/project storage abstraction
+├── vapora-telemetry/        # OpenTelemetry integration
+├── vapora-analytics/        # Event pipeline + usage stats
+├── vapora-worktree/         # Git worktree management
+└── vapora-doc-lifecycle/    # Documentation management
+```
+
+---
+
+## Rationale
+
+1. **Separation of Concerns**: Each crate owns a distinct architectural layer (backend API, agents, routing, knowledge graph, etc.)
+2. **Independent Testing**: 218+ tests can run in parallel across crates without cross-dependencies
+3. **Code Reusability**: Common utilities (`vapora-shared`) used by all crates without circular dependencies
+4. **Team Parallelization**: Multiple teams can develop on different crates simultaneously
+5. **Dependency Clarity**: Explicit `Cargo.toml` dependencies prevent accidental coupling
+6. **Version Management**: Centralized in root `Cargo.toml` via workspace dependencies prevents version skew
+
+---
+
+## Alternatives Considered
+
+### ❌ Monolithic Single Crate
+- All code in `/src/` directory
+- **Pros**: Simpler build, familiar structure
+- **Cons**: Tight coupling, slow compilation, testing all-or-nothing, hard to parallelize development
+
+### ❌ Multi-Repository
+- Separate Git repos for each component
+- **Pros**: Independent CI/CD, clear boundaries
+- **Cons**: Complex synchronization, dependency management nightmare, monorepo benefits lost (atomic commits)
+
+### ✅ Workspace Monorepo (CHOSEN)
+- 13 crates in single Git repo
+- **Pros**: Best of both worlds—clear boundaries + atomic commits + shared workspace config
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Clear architectural boundaries prevent accidental coupling
+- ✅ Parallel compilation and testing (cargo builds independent crates concurrently)
+- ✅ 218+ tests distributed across crates, faster feedback
+- ✅ Atomic commits across multiple components
+- ✅ Single CI/CD pipeline, shared version management
+- ✅ Easy debugging: each crate is independently debuggable
+
+**Cons**:
+- ⚠️ Workspace compilation overhead: must compile all dependencies even if using one crate
+- ⚠️ Slightly steeper learning curve for developers new to workspaces
+- ⚠️ Publishing to crates.io requires publishing each crate individually (not a concern for internal project)
+
+---
+
+## Implementation
+
+**Cargo.toml Workspace Configuration**:
+```toml
+[workspace]
+resolver = "2"
+
+members = [
+    "crates/vapora-backend",
+    "crates/vapora-frontend",
+    "crates/vapora-shared",
+    "crates/vapora-agents",
+    "crates/vapora-llm-router",
+    "crates/vapora-mcp-server",
+    "crates/vapora-tracking",
+    "crates/vapora-worktree",
+    "crates/vapora-knowledge-graph",
+    "crates/vapora-analytics",
+    "crates/vapora-swarm",
+    "crates/vapora-telemetry",
+]
+
+[workspace.package]
+version = "1.2.0"
+edition = "2021"
+rust-version = "1.75"
+```
+
+**Shared Dependencies** (defined once, inherited by all crates):
+```toml
+[workspace.dependencies]
+tokio = { version = "1.48", features = ["rt-multi-thread", "macros"] }
+serde = { version = "1.0", features = ["derive"] }
+surrealdb = { version = "2.3", features = ["kv-mem"] }
+```
+
+**Key Files**:
+- Root: `/Cargo.toml` (workspace definition)
+- Per-crate: `/crates/*/Cargo.toml` (individual dependencies)
+
+---
+
+## Verification
+
+```bash
+# Build entire workspace (runs in parallel)
+cargo build --workspace
+
+# Run all tests across workspace
+cargo test --workspace
+
+# Check dependency graph
+cargo tree
+
+# Verify no circular dependencies
+cargo tree --duplicates
+
+# Build single crate (to verify independence)
+cargo build -p vapora-backend
+cargo build -p vapora-agents
+cargo build -p vapora-llm-router
+```
+
+**Expected Output**:
+- All 13 crates compile without errors
+- 218+ tests pass
+- No circular dependency warnings
+- Each crate can be built independently
+
+---
+
+## Consequences
+
+### Short-term
+- Initial setup requires understanding workspace structure
+- Developers must navigate between crates
+- Testing must run across multiple crates (slower than single tests, but faster than monolith)
+
+### Long-term
+- Easy to add new crates as features grow (already added doc-lifecycle, mcp-server in later phases)
+- Scaling to multiple teams: each team owns 2-3 crates with clear boundaries
+- Maintenance: updating shared types in `vapora-shared` propagates to all dependent crates automatically
+
+### Maintenance
+- **Dependency Updates**: Update in `[workspace.dependencies]` once, all crates use new version
+- **Breaking Changes**: Require coordination across crates if shared types change
+- **Documentation**: Each crate should document its dependencies and public API
+
+---
+
+## References
+
+- [Cargo Workspace Documentation](https://doc.rust-lang.org/cargo/reference/workspaces.html)
+- Root `Cargo.toml`: `/Cargo.toml`
+- Crate list: `/crates/*/Cargo.toml`
+- CI validation: `.github/workflows/rust-ci.yml` (builds `--workspace`)

+# ADR-002: Axum como Backend Framework
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Backend Architecture Team
+**Technical Story**: Selecting REST API framework with optimal async/middleware composition for Tokio ecosystem
+
+---
+
+## Decision
+
+Usar **Axum 0.8.6** como framework REST API (no Actix-Web, no Rocket) para exponer 40+ endpoints de VAPORA.
+
+---
+
+## Rationale
+
+1. **Composable Middleware**: Tower ecosystem provides first-class composable middleware patterns
+2. **Type-Safe Routing**: Router defined as strong types (not string-based paths)
+3. **Tokio Ecosystem**: Built directly on Tokio (not abstraction layer), enabling precise async control
+4. **Extractors**: Powerful extractor system (`Json`, `State`, `Path`, custom extractors) reduces boilerplate
+5. **Performance**: Zero-copy response bodies, streaming support, minimal overhead
+
+---
+
+## Alternatives Considered
+
+### ❌ Actix-Web
+- Mature framework with larger ecosystem
+- **Cons**: Actor model adds complexity, different async patterns than Tokio, harder to integrate with Tokio primitives
+
+### ❌ Rocket
+- Developer-friendly API
+- **Cons**: Synchronous-first (async as afterthought), less composable, worse error handling
+
+### ✅ Axum (CHOSEN)
+- Minimal abstraction over Tokio/Tower
+- **Pros**: Composable, type-safe, Tokio-native, growing ecosystem
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Composable middleware (Tower trait-based)
+- ✅ Type-safe routing with strong types
+- ✅ Zero-cost abstractions, excellent performance
+- ✅ Perfect integration with Tokio async ecosystem
+- ✅ Streaming responses, WebSocket support built-in
+
+**Cons**:
+- ⚠️ Smaller ecosystem than Actix-Web
+- ⚠️ Steeper learning curve (requires understanding Tower traits)
+- ⚠️ Fewer third-party integrations available
+
+---
+
+## Implementation
+
+**Router Definition**:
+```rust
+let app = Router::new()
+    .route("/api/v1/projects", post(create_project).get(list_projects))
+    .route("/api/v1/projects/:id", get(get_project).put(update_project))
+    .route("/metrics", get(metrics_handler))
+    .layer(TraceLayer::new_for_http())
+    .layer(CorsLayer::permissive())
+    .layer(Extension(Arc::new(app_state)));
+
+let listener = TcpListener::bind("0.0.0.0:8001").await?;
+axum::serve(listener, app).await?;
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/main.rs:126-259` (router setup)
+- `/crates/vapora-backend/src/api/` (handlers)
+- `/crates/vapora-backend/Cargo.toml` (dependencies)
+
+---
+
+## Verification
+
+```bash
+# Build backend
+cargo build -p vapora-backend
+
+# Test API endpoints
+cargo test -p vapora-backend -- --nocapture
+
+# Run server and check health
+cargo run -p vapora-backend &
+curl http://localhost:8001/health
+curl http://localhost:8001/metrics
+```
+
+**Expected**: 40+ endpoints accessible, health check responds 200 OK, metrics endpoint returns Prometheus format
+
+---
+
+## Consequences
+
+- All HTTP handling must use Axum extractors (learning curve for team)
+- Request/response types must be serializable (integration with serde)
+- Middleware stacking order matters (defensive against bugs)
+- Easy to add WebSocket support later (Axum has built-in support)
+
+---

+# ADR-003: Leptos CSR-Only para Frontend
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Frontend Architecture Team
+**Technical Story**: Selecting WASM framework for client-side Kanban board UI
+
+---
+
+## Decision
+
+Usar **Leptos 0.8.12 en modo Client-Side Rendering (CSR)** para frontend WASM, sin SSR.
+
+---
+
+## Rationale
+
+1. **Fine-Grained Reactivity**: Similar to SolidJS (not virtual DOM), updates only affected nodes
+2. **WASM Performance**: Compiles to optimized WebAssembly
+3. **Deployment Simplicity**: CSR = static files + API, no server-side rendering complexity
+4. **VAPORA is a Platform**: Not a content site, so no SEO requirement
+
+---
+
+## Alternatives Considered
+
+### ❌ Yew
+- Virtual DOM model (slower updates)
+- Larger bundle size
+
+### ❌ Dioxus
+- Promising but less mature ecosystem
+
+### ✅ Leptos CSR (CHOSEN)
+- Fine-grained reactivity, excellent performance
+- No SEO needed for platform
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Excellent WASM performance
+- ✅ Simple deployment (static files)
+- ✅ UnoCSS integration for glassmorphism styling
+- ✅ Strong type safety in templates
+
+**Cons**:
+- ⚠️ No SEO (not applicable for platform)
+- ⚠️ Smaller ecosystem than React/Vue
+- ⚠️ Leptos SSR available but adds complexity
+
+---
+
+## Implementation
+
+**Leptos Component Example**:
+```rust
+#[component]
+fn ProjectBoard() -> impl IntoView {
+    let (projects, set_projects) = create_signal(vec![]);
+
+    view! {
+        <div class="grid grid-cols-3 gap-4">
+            <For each=projects key=|p| p.id let:project>
+                <ProjectCard project />
+            </For>
+        </div>
+    }
+}
+```
+
+**Key Files**:
+- `/crates/vapora-frontend/src/main.rs` (app root)
+- `/crates/vapora-frontend/src/pages/` (page components)
+- `/crates/vapora-frontend/Cargo.toml` (dependencies)
+
+---
+
+## Verification
+
+```bash
+# Build WASM
+trunk build --release
+
+# Serve and test
+trunk serve
+
+# Check bundle size
+ls -lh dist/index_*.wasm
+```
+
+**Expected**: WASM bundle < 500KB, components render reactively
+
+---
+
+## Consequences
+
+- Team must learn Leptos reactive system
+- SSR not available (acceptable trade-off)
+- Maintenance: Leptos updates follow Rust ecosystem
+
+---
+
+## References
+
+- [Leptos Documentation](https://leptos.dev/)
+- `/crates/vapora-frontend/src/` (source code)

+# ADR-004: SurrealDB como Database Único
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Backend Architecture Team
+**Technical Story**: Selecting unified multi-model database for relational, graph, and document workloads
+
+---
+
+## Decision
+
+Usar **SurrealDB 2.3** como base de datos única (no PostgreSQL + Neo4j, no MongoDB puro).
+
+---
+
+## Rationale
+
+1. **Multi-Model en una sola DB**: Relational (SQL), graph (queries), document (JSON) sin múltiples conexiones
+2. **Multi-Tenancy Nativa**: SurrealDB scopes permiten aislamiento a nivel de database sin lógica en aplicación
+3. **WebSocket Connection**: Soporte nativo de conexiones bidireccionales (vs REST)
+4. **SurrealQL**: Sintaxis SQL-like + graph traversal en una sola query language
+5. **VAPORA Requirements**: Almacena projects (relational), agent relationships (graph), execution history (document)
+
+---
+
+## Alternatives Considered
+
+### ❌ PostgreSQL + Neo4j (Two Database Approach)
+- **Pros**: Maduro, comunidad grande, especializados
+- **Cons**: Sincronización entre dos DBs, dos conexiones, transacciones distribuidas complejas
+
+### ❌ MongoDB Puro (Document Only)
+- **Pros**: Flexible, escalable
+- **Cons**: Sin soporte graph nativo, requiere aplicación para traversal, sin SQL
+
+### ✅ SurrealDB (CHOSEN)
+- Unifica relational + graph + document
+- Multi-tenancy built-in
+- WebSocket para real-time
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Una sola DB para todos los modelos de datos
+- ✅ Scopes para isolamiento de tenants (no en aplicación)
+- ✅ Transactions ACID
+- ✅ SurrealQL es SQL + graph en una query
+- ✅ WebSocket bidireccional
+
+**Cons**:
+- ⚠️ Ecosistema más pequeño que PostgreSQL
+- ⚠️ Drivers/herramientas menos maduras
+- ⚠️ Soporte de clusters más limitado (vs Postgres)
+
+---
+
+## Implementation
+
+**Database Connection**:
+```rust
+// crates/vapora-backend/src/main.rs:48-59
+let db = surrealdb::Surreal::new::<surrealdb::engine::remote::ws::Ws>(
+    &config.database.url
+).await?;
+
+db.signin(surrealdb::opt::auth::Root {
+    username: "root",
+    password: "root",
+}).await?;
+
+db.use_ns("vapora").use_db("main").await?;
+```
+
+**Scope-Based Multi-Tenancy**:
+```rust
+// All queries use scope for tenant isolation
+db.query("SELECT * FROM projects WHERE tenant_id = $tenant_id")
+    .bind(("tenant_id", tenant_id))
+    .await?
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/main.rs:45-59` (connection setup)
+- `/crates/vapora-backend/src/services/` (query implementations)
+- `/crates/vapora-shared/src/models.rs` (Project, Task, Agent models with tenant_id)
+
+---
+
+## Verification
+
+```bash
+# Connect to SurrealDB
+surreal sql --conn ws://localhost:8000 --user root --pass root
+
+# Verify namespace and database exist
+USE ns vapora db main;
+INFO FOR DATABASE;
+
+# Test multi-tenant query
+SELECT * FROM projects WHERE tenant_id = 'workspace:123';
+
+# Test graph traversal
+SELECT
+    *,
+    ->assigned_to->agents AS assigned_agents
+FROM tasks
+WHERE project_id = 'project:123';
+
+# Run backend tests with SurrealDB
+cargo test -p vapora-backend -- --nocapture
+```
+
+**Expected Output**:
+- SurrealDB connects via WebSocket
+- Projects table exists and is queryable
+- Graph relationships (->assigned_to) resolve
+- Multi-tenant queries filter correctly
+- 79+ backend tests pass
+
+---
+
+## Consequences
+
+### Data Model Changes
+- All tables must include `tenant_id` field for scoping
+- Relations use SurrealDB's `->` edge syntax for graph queries
+- No foreign key constraints (SurrealDB uses references instead)
+
+### Query Patterns
+- Services layer queries must include tenant_id filter (defense-in-depth)
+- SurrealQL instead of raw SQL learning curve for team
+- Graph traversal enables efficient knowledge graph queries
+
+### Scaling Considerations
+- Horizontal scaling requires clustering (vs Postgres replication)
+- Backup/recovery different from traditional databases (see ADR-020)

+# ADR-005: NATS JetStream para Agent Coordination
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Agent Architecture Team
+**Technical Story**: Selecting persistent message broker for reliable agent task queuing
+
+---
+
+## Decision
+
+Usar **async-nats 0.45 con JetStream** para coordinación de agentes (no Redis Pub/Sub, no RabbitMQ).
+
+---
+
+## Rationale
+
+1. **At-Least-Once Delivery**: JetStream garantiza persistencia + retries (vs Redis Pub/Sub que pierde mensajes)
+2. **Lightweight**: Ninguna dependencia pesada (vs RabbitMQ/Kafka setup)
+3. **Async Native**: Diseñado para Tokio (mismo runtime que VAPORA)
+4. **VAPORA Use Case**: Coordinar tareas entre múltiples agentes con garantías de entrega
+
+---
+
+## Alternatives Considered
+
+### ❌ Redis Pub/Sub
+- **Pros**: Simple, fast
+- **Cons**: Sin persistencia, mensajes perdidos si broker cae
+
+### ❌ RabbitMQ
+- **Pros**: Maduro, confiable
+- **Cons**: Pesado, require seperate server, más complejidad operacional
+
+### ✅ NATS JetStream (CHOSEN)
+- At-least-once delivery
+- Lightweight
+- Tokio-native async
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Persistencia garantizada (JetStream)
+- ✅ Retries automáticos
+- ✅ Bajo overhead operacional
+- ✅ Integración natural con Tokio
+
+**Cons**:
+- ⚠️ Cluster setup requiere configuración adicional
+- ⚠️ Menos tooling que RabbitMQ
+- ⚠️ Fallback a in-memory si NATS cae (degrada a at-most-once)
+
+---
+
+## Implementation
+
+**Task Publishing**:
+```rust
+// crates/vapora-agents/src/coordinator.rs
+let client = async_nats::connect(&nats_url).await?;
+let jetstream = async_nats::jetstream::new(client);
+
+// Publish task assignment
+jetstream.publish("tasks.assigned", serde_json::to_vec(&task_msg)?).await?;
+```
+
+**Agent Subscription**:
+```rust
+// Subscribe to task queue
+let subscriber = jetstream
+    .subscribe_durable("tasks.assigned", "agent-consumer")
+    .await?;
+
+// Process incoming tasks
+while let Some(message) = subscriber.next().await {
+    let task: TaskMessage = serde_json::from_slice(&message.payload)?;
+    process_task(task).await?;
+    message.ack().await?; // Acknowledge after successful processing
+}
+```
+
+**Key Files**:
+- `/crates/vapora-agents/src/coordinator.rs:53-72` (message dispatch)
+- `/crates/vapora-agents/src/messages.rs` (message types)
+- `/crates/vapora-backend/src/api/` (task creation publishes to JetStream)
+
+---
+
+## Verification
+
+```bash
+# Start NATS with JetStream support
+docker run -d -p 4222:4222 nats:latest -js
+
+# Create stream and consumer
+nats stream add TASKS --subjects 'tasks.assigned' --storage file

+# Monitor message throughput
+nats sub 'tasks.assigned' --raw
+
+# Test agent coordination
+cargo test -p vapora-agents -- --nocapture
+
+# Check message processing
+nats stats
+```
+
+**Expected Output**:
+- JetStream stream created with persistence
+- Messages published to `tasks.assigned` persisted
+- Agent subscribers receive and acknowledge messages
+- Retries work if agent processing fails
+- All agent tests pass
+
+---
+
+## Consequences
+
+### Message Queue Management
+- Streams must be pre-created (infra responsibility)
+- Retention policies configured per stream (age, size limits)
+- Consumer groups enable load-balanced processing
+
+### Failure Modes
+- If NATS unavailable: Agents fallback to in-memory queue (graceful degradation)
+- Lost messages only if dual failure (server down + no backup)
+- See disaster recovery plan for NATS clustering
+
+### Scaling
+- Multiple agents subscribe to same consumer group (load balancing)
+- One message processed by one agent (exclusive delivery)
+- Ordering preserved within subject

+# ADR-006: Rig Framework para LLM Agent Orchestration
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: LLM Architecture Team
+**Technical Story**: Selecting Rust-native framework for LLM agent tool calling and streaming
+
+---
+
+## Decision
+
+Usar **rig-core 0.15** para orquestación de agentes LLM (no LangChain, no SDKs directos de proveedores).
+
+---
+
+## Rationale
+
+1. **Rust-Native**: Sin dependencias Python, compila a binario standalone
+2. **Tool Calling Support**: First-class abstraction para function calling
+3. **Streaming**: Built-in streaming de respuestas
+4. **Minimal Abstraction**: Wrapper thin sobre APIs de proveedores (no over-engineering)
+5. **Type Safety**: Schemas automáticos para tool definitions
+
+---
+
+## Alternatives Considered
+
+### ❌ LangChain (Python Bridge)
+- **Pros**: Muy maduro, mucho tooling
+- **Cons**: Requiere Python runtime, complejidad de IPC
+
+### ❌ Direct Provider SDKs (Claude, OpenAI, etc.)
+- **Pros**: Control total
+- **Cons**: Reimplementar tool calling, streaming, error handling múltiples veces
+
+### ✅ Rig Framework (CHOSEN)
+- Rust-native, thin abstraction
+- Tool calling built-in
+- Streaming support
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Rust-native (no Python dependency)
+- ✅ Tool calling abstraction reducida
+- ✅ Streaming responses
+- ✅ Type-safe schemas
+- ✅ Minimal memory footprint
+
+**Cons**:
+- ⚠️ Comunidad más pequeña que LangChain
+- ⚠️ Menos ejemplos/tutorials disponibles
+- ⚠️ Actualización menos frecuente que alternatives
+
+---
+
+## Implementation
+
+**Agent with Tool Calling**:
+```rust
+// crates/vapora-llm-router/src/providers.rs
+use rig::client::Client;
+use rig::completion::Prompt;
+
+let client = rig::client::OpenAIClient::new(&api_key);
+
+// Define tool schema
+let calculate_tool = rig::tool::Tool {
+    name: "calculate".to_string(),
+    description: "Perform arithmetic calculation".to_string(),
+    schema: json!({
+        "type": "object",
+        "properties": {
+            "expression": {"type": "string"}
+        }
+    }),
+};
+
+// Call with tool
+let response = client
+    .post_chat()
+    .preamble("You are a helpful assistant")
+    .user_message("What is 2 + 2?")
+    .tool(calculate_tool)
+    .call()
+    .await?;
+```
+
+**Streaming Responses**:
+```rust
+// Stream chunks as they arrive
+let mut stream = client
+    .post_chat()
+    .user_message(prompt)
+    .stream()
+    .await?;
+
+while let Some(chunk) = stream.next().await {
+    match chunk {
+        Ok(text) => println!("{}", text),
+        Err(e) => eprintln!("Error: {:?}", e),
+    }
+}
+```
+
+**Key Files**:
+- `/crates/vapora-llm-router/src/providers.rs` (provider implementations)
+- `/crates/vapora-llm-router/src/router.rs` (routing logic)
+- `/crates/vapora-agents/src/executor.rs` (agent task execution)
+
+---
+
+## Verification
+
+```bash
+# Test tool calling
+cargo test -p vapora-llm-router test_tool_calling
+
+# Test streaming
+cargo test -p vapora-llm-router test_streaming_response
+
+# Integration test with real provider
+cargo test -p vapora-llm-router test_agent_execution -- --nocapture
+
+# Benchmark tool calling latency
+cargo bench -p vapora-llm-router bench_tool_response_time
+```
+
+**Expected Output**:
+- Tools invoked correctly with parameters
+- Streaming chunks received in order
+- Agent executes tasks and returns results
+- Latency < 100ms per tool call
+
+---
+
+## Consequences
+
+### Developer Workflow
+- Tool schemas defined in code (type-safe)
+- No Python bridge debugging complexity
+- Single-language stack (all Rust)
+
+### Performance
+- Minimal latency (direct to provider APIs)
+- Streaming reduces perceived latency
+- Tool calling has <50ms overhead
+
+### Future Extensibility
+- Adding new providers: implement `LLMClient` trait
+- Custom tools: define schema + handler in Rust
+- See ADR-007 (Multi-Provider Support)
+
+---

+<hr />
+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Cost Optimization</strong>: Barato (Ollama) → Rápido (Gemini) → Confiable (Claude/GPT-4)</li>
+<li><strong>Resilience</strong>: Si un provider falla, fallback automático al siguiente</li>
+<li><strong>Task-Specific Selection</strong>:
+<ul>
+<li>Architecture → Claude Opus (mejor reasoning)</li>
+<li>Code generation → GPT-4 (mejor código)</li>
+<li>Quick queries → Gemini Flash (más rápido)</li>
+<li>Development/testing → Ollama (gratis)</li>
+</ul>
+</li>
+<li><strong>Avoid Vendor Lock-in</strong>: Múltiples proveedores previene dependencia única</li>

+<h3 id="-single-provider-only-claude"><a class="header" href="#-single-provider-only-claude">❌ Single Provider Only (Claude)</a></h3>
+<ul>
+<li><strong>Pros</strong>: Simplidad</li>

+# ADR-007: Multi-Provider LLM Support (Claude, OpenAI, Gemini, Ollama)
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: LLM Architecture Team
+**Technical Story**: Enabling fallback across multiple LLM providers with cost optimization
+
+---
+
+## Decision
+
+Soporte para **4 providers: Claude, OpenAI, Gemini, Ollama** via abstracción `LLMClient` trait con fallback chain automático.
+
+---
+
+## Rationale
+
+1. **Cost Optimization**: Barato (Ollama) → Rápido (Gemini) → Confiable (Claude/GPT-4)
+2. **Resilience**: Si un provider falla, fallback automático al siguiente
+3. **Task-Specific Selection**:
+   - Architecture → Claude Opus (mejor reasoning)
+   - Code generation → GPT-4 (mejor código)
+   - Quick queries → Gemini Flash (más rápido)
+   - Development/testing → Ollama (gratis)
+4. **Avoid Vendor Lock-in**: Múltiples proveedores previene dependencia única
+
+---
+
+## Alternatives Considered
+
+### ❌ Single Provider Only (Claude)
+- **Pros**: Simplidad
+- **Cons**: Vendor lock-in, sin fallback si servicio cae, costo alto
+
+### ❌ Custom API Abstraction (DIY)
+- **Pros**: Control total
+- **Cons**: Maintenance pesada, re-implementar streaming/errors/tokens para cada provider
+
+### ✅ Multiple Providers with Fallback (CHOSEN)
+- Flexible, resiliente, cost-optimized
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Fallback automático si provider primario no disponible
+- ✅ Cost efficiency: Ollama $0, Gemini barato, Claude premium
+- ✅ Resilience: No single point of failure
+- ✅ Task-specific selection: Usar mejor tool para cada job
+- ✅ No vendor lock-in
+
+**Cons**:
+- ⚠️ Múltiples API keys a gestionar (secrets management)
+- ⚠️ Complicación de testing (mocks para múltiples providers)
+- ⚠️ Latency variance (diferentes speeds entre providers)
+
+---
+
+## Implementation
+
+**Provider Trait Abstraction**:
+```rust
+// crates/vapora-llm-router/src/providers.rs
+pub trait LLMClient: Send + Sync {
+    async fn complete(&self, prompt: &str) -> Result<String>;
+    async fn stream_complete(&self, prompt: &str) -> Result<BoxStream<String>>;
+    fn provider_name(&self) -> &str;
+    fn cost_per_token(&self) -> f64;
+}
+
+// Implementations
+impl LLMClient for ClaudeClient { /* ... */ }
+impl LLMClient for OpenAIClient { /* ... */ }
+impl LLMClient for GeminiClient { /* ... */ }
+impl LLMClient for OllamaClient { /* ... */ }
+```
+
+**Fallback Chain Router**:
+```rust
+// crates/vapora-llm-router/src/router.rs
+pub async fn route_task(task: &Task) -> Result<String> {
+    let providers = vec![
+        select_primary_provider(&task),  // Task-specific: Claude/GPT-4/Gemini
+        "gemini".to_string(),             // Fallback: Gemini
+        "openai".to_string(),             // Fallback: OpenAI
+        "ollama".to_string(),             // Last resort: Local
+    ];
+
+    for provider_name in providers {
+        match self.clients.get(provider_name).complete(&prompt).await {
+            Ok(response) => {
+                metrics::increment_provider_success(&provider_name);
+                return Ok(response);
+            }
+            Err(e) => {
+                tracing::warn!("Provider {} failed: {:?}, trying next", provider_name, e);
+                metrics::increment_provider_failure(&provider_name);
+            }
+        }
+    }
+    Err(VaporaError::AllProvidersFailed)
+}
+```
+
+**Configuration**:
+```toml
+# config/llm-routing.toml
+[[providers]]
+name = "claude"
+model = "claude-3-opus-20240229"
+api_key_env = "ANTHROPIC_API_KEY"
+priority = 1
+cost_per_1k_tokens = 0.015
+
+[[providers]]
+name = "openai"
+model = "gpt-4"
+api_key_env = "OPENAI_API_KEY"
+priority = 2
+cost_per_1k_tokens = 0.03
+
+[[providers]]
+name = "gemini"
+model = "gemini-2.0-flash"
+api_key_env = "GOOGLE_API_KEY"
+priority = 3
+cost_per_1k_tokens = 0.005
+
+[[providers]]
+name = "ollama"
+url = "http://localhost:11434"
+model = "llama2"
+priority = 4
+cost_per_1k_tokens = 0.0
+
+[[routing_rules]]
+pattern = "architecture"
+provider = "claude"
+
+[[routing_rules]]
+pattern = "code_generation"
+provider = "openai"
+
+[[routing_rules]]
+pattern = "quick_query"
+provider = "gemini"
+```
+
+**Key Files**:
+- `/crates/vapora-llm-router/src/providers.rs` (trait implementations)
+- `/crates/vapora-llm-router/src/router.rs` (routing logic + fallback)
+- `/crates/vapora-llm-router/src/cost_tracker.rs` (token counting per provider)
+
+---
+
+## Verification
+
+```bash
+# Test each provider individually
+cargo test -p vapora-llm-router test_claude_provider
+cargo test -p vapora-llm-router test_openai_provider
+cargo test -p vapora-llm-router test_gemini_provider
+cargo test -p vapora-llm-router test_ollama_provider
+
+# Test fallback chain
+cargo test -p vapora-llm-router test_fallback_chain
+
+# Benchmark costs and latencies
+cargo run -p vapora-llm-router --bin benchmark -- --providers all --samples 100
+
+# Test task routing
+cargo test -p vapora-llm-router test_task_routing
+```
+
+**Expected Output**:
+- All 4 providers respond correctly when available
+- Fallback triggers when primary provider fails
+- Cost tracking accurate per provider
+- Task routing selects appropriate provider
+- Claude used for architecture, GPT-4 for code, etc.
+
+---
+
+## Consequences
+
+### Operational
+- 4 API keys required (managed via secrets)
+- Cost monitoring per provider (see ADR-015, Budget Enforcement)
+- Provider status pages monitored for incidents
+
+### Metrics & Monitoring
+- Track success rate per provider
+- Track latency per provider
+- Alert if primary provider consistently fails
+- Report costs broken down by provider
+
+### Development
+- Mocking tests for each provider
+- Integration tests with real providers (limited to avoid costs)
+- Provider selection logic well-documented
+

+# ADR-008: Tokio Multi-Threaded Runtime
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Runtime Architecture Team
+**Technical Story**: Selecting async runtime for I/O-heavy workload (API, DB, LLM calls)
+
+---
+
+## Decision
+
+Usar **Tokio multi-threaded runtime** con configuración default (no single-threaded, no custom thread pool).
+
+---
+
+## Rationale
+
+1. **I/O-Heavy Workload**: VAPORA hace many concurrent calls (SurrealDB, NATS, LLM APIs, WebSockets)
+2. **Multi-Core Scalability**: Multi-threaded distributes work across cores eficientemente
+3. **Production-Ready**: Tokio es de-facto estándar en Rust async ecosystem
+4. **Minimal Config Overhead**: Default settings tuned para la mayoría de casos
+
+---
+
+## Alternatives Considered
+
+### ❌ Single-Threaded Tokio (`tokio::main` single_threaded)
+- **Pros**: Simpler to debug, predictable ordering
+- **Cons**: Single core only, no scaling, inadequate for concurrent workload
+
+### ❌ Custom ThreadPool
+- **Pros**: Full control
+- **Cons**: Manual scheduling, error-prone, maintenance burden
+
+### ✅ Tokio Multi-Threaded (CHOSEN)
+- Production-ready, well-tuned, scales across cores
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Scales across all CPU cores
+- ✅ Efficient I/O multiplexing (epoll on Linux, kqueue on macOS)
+- ✅ Proven in production systems
+- ✅ Built-in task spawning with `tokio::spawn`
+- ✅ Graceful shutdown handling
+
+**Cons**:
+- ⚠️ More complex debugging (multiple threads)
+- ⚠️ Potential data race if `Send/Sync` bounds not respected
+- ⚠️ Memory overhead (per-thread stacks)
+
+---
+
+## Implementation
+
+**Runtime Configuration**:
+```rust
+// crates/vapora-backend/src/main.rs:26
+#[tokio::main]
+async fn main() -> Result<()> {
+    // Default: worker threads = num_cpus(), stack size = 2MB
+    // Equivalent to:
+    // let rt = tokio::runtime::Builder::new_multi_thread()
+    //     .worker_threads(num_cpus::get())
+    //     .enable_all()
+    //     .build()?;
+}
+```
+
+**Async Task Spawning**:
+```rust
+// Spawn independent task (runs concurrently on available worker)
+tokio::spawn(async {
+    let result = expensive_operation().await;
+    handle_result(result).await;
+});
+```
+
+**Blocking Code in Async Context**:
+```rust
+// Block sync code without blocking entire executor
+let result = tokio::task::block_in_place(|| {
+    // CPU-bound work or blocking I/O (file system, etc)
+    expensive_computation()
+});
+```
+
+**Graceful Shutdown**:
+```rust
+// Listen for Ctrl+C
+let shutdown = tokio::signal::ctrl_c();
+
+tokio::select! {
+    _ = shutdown => {
+        info!("Shutting down gracefully...");
+        // Cancel in-flight tasks, drain channels, close connections
+    }
+    _ = run_server() => {}
+}
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/main.rs:26` (Tokio main)
+- `/crates/vapora-agents/src/bin/server.rs` (Agent server with Tokio)
+- `/crates/vapora-llm-router/src/router.rs` (Concurrent LLM calls via tokio::spawn)
+
+---
+
+## Verification
+
+```bash
+# Check runtime worker threads at startup
+RUST_LOG=tokio=debug cargo run -p vapora-backend 2>&1 | grep "worker"
+
+# Monitor CPU usage across cores
+top -H -p $(pgrep -f vapora-backend)
+
+# Test concurrent task spawning
+cargo test -p vapora-backend test_concurrent_requests
+
+# Profile thread behavior
+cargo flamegraph --bin vapora-backend -- --profile cpu
+
+# Stress test with load generator
+wrk -t 4 -c 100 -d 30s http://localhost:8001/health
+
+# Check task wakeups and efficiency
+cargo run -p vapora-backend --release
+# In another terminal:
+perf record -p $(pgrep -f vapora-backend) sleep 5
+perf report | grep -i "wakeup\|context"
+```
+
+**Expected Output**:
+- Worker threads = number of CPU cores
+- Concurrent requests handled efficiently
+- CPU usage distributed across cores
+- Low context switching overhead
+- Latency p99 < 100ms for simple endpoints
+
+---
+
+## Consequences
+
+### Concurrency Model
+- Use `Arc<>` for shared state (cheap clones)
+- Use `tokio::sync::RwLock`, `Mutex`, `broadcast` for synchronization
+- Avoid blocking operations in async code (use `block_in_place`)
+
+### Error Handling
+- Panics in spawned tasks don't kill runtime (captured via `JoinHandle`)
+- Use `.await?` for proper error propagation
+- Set panic hook for graceful degradation
+
+### Monitoring
+- Track task queue depth (available via `tokio-console`)
+- Monitor executor CPU usage
+- Alert if thread starvation detected
+
+### Performance Tuning
+- Default settings adequate for most workloads
+- Only customize if profiling shows bottleneck
+- Typical: num_workers = num_cpus, stack size = 2MB

+# ADR-009: Istio Service Mesh para Kubernetes
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Kubernetes Architecture Team
+**Technical Story**: Adding zero-trust security and traffic management for microservices in K8s
+
+---
+
+## Decision
+
+Usar **Istio** como service mesh para mTLS, traffic management, rate limiting, y observability en Kubernetes.
+
+---
+
+## Rationale
+
+1. **mTLS Out-of-Box**: Automático TLS entre servicios sin código cambios
+2. **Zero-Trust**: Enforced mutual TLS por defecto
+3. **Traffic Management**: Circuit breakers, retries, timeouts sin lógica en aplicación
+4. **Observability**: Tracing automático, metrics collection
+5. **VAPORA Multiservice**: 4 deployments (backend, agents, LLM router, frontend) necesitan seguridad inter-service
+
+---
+
+## Alternatives Considered
+
+### ❌ Plain Kubernetes Networking
+- **Pros**: Simpler setup, fewer components
+- **Cons**: No mTLS, no traffic policies, manual observability
+
+### ❌ Linkerd (Minimal Service Mesh)
+- **Pros**: Lighter weight than Istio
+- **Cons**: Less feature-rich, smaller ecosystem
+
+### ✅ Istio (CHOSEN)
+- Industry standard, feature-rich, VAPORA deployment compatible
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Automatic mTLS between services
+- ✅ Declarative traffic policies (no code changes)
+- ✅ Circuit breakers and retries built-in
+- ✅ Integrated observability (tracing, metrics)
+- ✅ Gradual rollout support (canary deployments)
+- ✅ Rate limiting and authentication policies
+
+**Cons**:
+- ⚠️ Operational complexity (data plane + control plane)
+- ⚠️ Memory overhead per pod (sidecar proxy)
+- ⚠️ Debugging complexity (multiple proxy layers)
+- ⚠️ Certification/certificate rotation management
+
+---
+
+## Implementation
+
+**Installation**:
+```bash
+# Install Istio
+istioctl install --set profile=production -y
+
+# Enable sidecar injection for namespace
+kubectl label namespace vapora istio-injection=enabled
+
+# Verify installation
+kubectl get pods -n istio-system
+```
+
+**Service Mesh Configuration**:

+
+**Key Files**:
+- `/kubernetes/platform/istio-config.yaml` (Istio configuration)
+- `/kubernetes/base/` (Deployment manifests with sidecar injection)
+- `istioctl` commands for traffic management
+
+---
+
+## Verification
+
+```bash
+# Check sidecar injection
+kubectl get pods -n vapora -o jsonpath='{.items[*].spec.containers[*].name}' | grep istio-proxy
+
+# List virtual services
+kubectl get virtualservices -n vapora
+
+# Check mTLS status
+istioctl analyze -n vapora
+
+# Monitor traffic between services
+kubectl logs -n vapora deployment/vapora-backend -c istio-proxy --tail 20

+
+# Check metrics collection
+kubectl port-forward -n istio-system svc/prometheus 9090:9090
+# Open http://localhost:9090 and query: rate(istio_request_total[1m])
+```
+
+**Expected Output**:
+- All pods have istio-proxy sidecar
+- VirtualServices and DestinationRules configured
+- mTLS enabled between services
+- Circuit breaker protects against cascading failures
+- Authorization policies enforce least-privilege access
+- Metrics collected for all inter-service traffic
+
+---
+
+## Consequences
+
+### Operational
+- Certificate rotation automatic (Istio CA)
+- Service-to-service debugging requires understanding proxy layers
+- Traffic policies applied without code redeployment
+
+### Performance
+- Sidecar proxy adds ~5-10ms latency per call
+- Memory per pod: +50MB for proxy container
+- Worth the security/observability trade-off
+
+### Debugging
+- Use `istioctl analyze` to diagnose issues
+- Envoy proxy logs in sidecar containers
+- Distributed tracing via Jaeger/Zipkin integration
+
+### Scaling
+- Automatic load balancing via DestinationRule
+- Circuit breaker prevents thundering herd
+- Support for canary rollouts via traffic splitting

+<p><strong>Status</strong>: Accepted | Implemented
+<strong>Date</strong>: 2024-11-01
+<strong>Deciders</strong>: Security Architecture Team
+<strong>Technical Story</strong>: Implementing declarative RBAC with audit-friendly policies</p>
+<hr />
+<h2 id="decision"><a class="header" href="#decision">Decision</a></h2>
+<p>Usar <strong>Cedar policy engine</strong> para autorización declarativa (no custom RBAC, no Casbin).</p>
+<hr />
+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Declarative Policies</strong>: Separar políticas de autorización de lógica de código</li>
+<li><strong>Auditable</strong>: Políticas versionables en Git, fácil de revisar</li>
+<li><strong>AWS Proven</strong>: Usado internamente en AWS, production-proven</li>
+<li><strong>Type Safe</strong>: Schemas para resources y principals</li>
+<li><strong>No Vendor Lock-in</strong>: Open source, portable</li>
+</ol>

+<h2 id="alternatives-considered"><a class="header" href="#alternatives-considered">Alternatives Considered</a></h2>
+<h3 id="-custom-rbac-implementation"><a class="header" href="#-custom-rbac-implementation">❌ Custom RBAC Implementation</a></h3>
+<ul>
+<li><strong>Pros</strong>: Full control</li>
+<li><strong>Cons</strong>: Mantenimiento pesada, fácil de introducir vulnerabilidades</li>
+</ul>
+<h3 id="-casbin-policy-engine"><a class="header" href="#-casbin-policy-engine">❌ Casbin (Policy Engine)</a></h3>
+<ul>

+<hr />
+<h2 id="trade-offs"><a class="header" href="#trade-offs">Trade-offs</a></h2>
+<p><strong>Pros</strong>:</p>
+<ul>
+<li>✅ Declarative policies separate from code</li>
+<li>✅ Easy to audit and version control</li>
+<li>✅ Type-safe schema validation</li>
+<li>✅ AWS production-proven</li>
+<li>✅ Support for complex hierarchies (teams, orgs)</li>
+</ul>
+<p><strong>Cons</strong>:</p>
+<ul>
+<li>⚠️ Learning curve (new policy language)</li>
+<li>⚠️ Policies must be pre-compiled for performance</li>
+<li>⚠️ Smaller community than Casbin</li>

+# ADR-010: Cedar Policy Engine para Authorization
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Security Architecture Team
+**Technical Story**: Implementing declarative RBAC with audit-friendly policies
+
+---
+
+## Decision
+
+Usar **Cedar policy engine** para autorización declarativa (no custom RBAC, no Casbin).
+
+---
+
+## Rationale
+
+1. **Declarative Policies**: Separar políticas de autorización de lógica de código
+2. **Auditable**: Políticas versionables en Git, fácil de revisar
+3. **AWS Proven**: Usado internamente en AWS, production-proven
+4. **Type Safe**: Schemas para resources y principals
+5. **No Vendor Lock-in**: Open source, portable
+
+---
+
+## Alternatives Considered
+
+### ❌ Custom RBAC Implementation
+- **Pros**: Full control
+- **Cons**: Mantenimiento pesada, fácil de introducir vulnerabilidades
+
+### ❌ Casbin (Policy Engine)
+- **Pros**: Flexible
+- **Cons**: Menos maduro en Rust ecosystem que Cedar
+
+### ✅ Cedar (CHOSEN)
+- Declarative, auditable, production-proven, AWS-backed
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Declarative policies separate from code
+- ✅ Easy to audit and version control
+- ✅ Type-safe schema validation
+- ✅ AWS production-proven
+- ✅ Support for complex hierarchies (teams, orgs)
+
+**Cons**:
+- ⚠️ Learning curve (new policy language)
+- ⚠️ Policies must be pre-compiled for performance
+- ⚠️ Smaller community than Casbin
+
+---
+
+## Implementation
+
+**Policy Definition**:
+```cedar
+// policies/authorization.cedar
+
+// Allow owners full access to projects
+permit(
+    principal,
+    action,
+    resource
+)
+when {
+    principal.role == "owner"
+};
+
+// Allow members to create tasks
+permit(
+    principal in [User],
+    action == Action::"create_task",
+    resource in [Project]
+)
+when {
+    principal.team_id == resource.team_id &&
+    principal.role in ["owner", "member"]
+};
+
+// Deny editing completed tasks
+forbid(
+    principal,
+    action == Action::"update_task",
+    resource in [Task]
+)
+when {
+    resource.status == "done"
+};
+
+// Allow viewing with viewer role
+permit(
+    principal,
+    action == Action::"read",
+    resource
+)
+when {
+    principal.role == "viewer"
+};
+```
+
+**Authorization Check in Backend**:
+```rust
+// crates/vapora-backend/src/api/projects.rs
+use cedar_policy::{Authorizer, Request, Entity, Entities};
+
+async fn get_project(
+    State(app_state): State<AppState>,
+    Path(project_id): Path<String>,
+) -> Result<Json<Project>, ApiError> {
+    let user = get_current_user()?;
+
+    // Create authorization request
+    let request = Request::new(
+        user.into_entity(),
+        action("read"),
+        resource("project", &project_id),
+        None,
+    )?;
+
+    // Load policies and entities
+    let policies = app_state.cedar_policies();
+    let entities = app_state.cedar_entities();
+
+    // Authorize
+    let authorizer = Authorizer::new();
+    let response = authorizer.is_authorized(&request, &policies, &entities)?;
+
+    match response.decision {
+        Decision::Allow => {
+            let project = app_state
+                .project_service
+                .get_project(&user.tenant_id, &project_id)
+                .await?;
+            Ok(Json(project))
+        }
+        Decision::Deny => Err(ApiError::Forbidden),
+    }
+}
+```
+
+**Entity Schema**:
+```rust
+// crates/vapora-backend/src/auth/entities.rs
+pub struct User {
+    pub id: String,
+    pub role: UserRole,
+    pub tenant_id: String,
+}
+
+pub struct Project {
+    pub id: String,
+    pub tenant_id: String,
+    pub status: ProjectStatus,
+}
+
+// Convert to Cedar entities
+impl From<User> for cedar_policy::Entity {
+    fn from(user: User) -> Self {
+        // Serialized to Cedar format
+    }
+}
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/auth/` (Cedar integration)
+- `/crates/vapora-backend/src/api/` (authorization checks)
+- `/policies/authorization.cedar` (policy definitions)
+
+---
+
+## Verification
+
+```bash
+# Validate policy syntax
+cedar validate --schema schemas/schema.json --policies policies/authorization.cedar
+
+# Test authorization decision
+cedar evaluate \
+  --schema schemas/schema.json \
+  --policies policies/authorization.cedar \
+  --entities entities.json \
+  --request '{"principal": "User:alice", "action": "Action::read", "resource": "Project:123"}'
+
+# Run authorization tests
+cargo test -p vapora-backend test_cedar_authorization
+
+# Test edge cases
+cargo test -p vapora-backend test_forbidden_access
+cargo test -p vapora-backend test_hierarchical_permissions
+```
+
+**Expected Output**:
+- Policies validate without syntax errors
+- Owners have full access
+- Members can create tasks in their team
+- Viewers can only read
+- Completed tasks cannot be edited
+- All tests pass
+
+---
+
+## Consequences
+
+### Authorization Model
+- Three roles: Owner, Member, Viewer
+- Hierarchical teams (can nest permissions)
+- Resource-scoped access (per project, per task)
+- Audit trail of policy decisions
+
+### Policy Management
+- Policies versioned in Git
+- Policy changes require code review
+- Centralized policy repository
+- No runtime policy compilation (pre-compiled)
+
+### Performance
+- Policy evaluation cached (policies don't change often)
+- Entity resolution cached per request
+- Negligible latency overhead (<1ms)
+
+### Scaling
+- Policies apply across all services
+- Cedar policies portable to other services
+- Centralized policy management
+

+# ADR-011: SecretumVault para Secrets Management
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Security Architecture Team
+**Technical Story**: Securing API keys and credentials with post-quantum cryptography
+
+---
+
+## Decision
+
+Usar **SecretumVault** para gestión de secrets con criptografía post-quantum (no HashiCorp Vault, no plain K8s secrets).
+
+---
+
+## Rationale
+
+1. **Post-Quantum Cryptography**: Protege contra ataques futuros con quantum computers
+2. **Rust-Native**: Sin dependencias externas, compila a binario standalone
+3. **API Key Security**: Encriptación at-rest para LLM API keys
+4. **Audit Logging**: Todas las operaciones de secretos registradas
+5. **Future-Proof**: Prepara a VAPORA para amenazas de seguridad del futuro
+
+---
+
+## Alternatives Considered
+
+### ❌ HashiCorp Vault
+- **Pros**: Maduro, enterprise-grade
+- **Cons**: Externa dependencia, operacional overhead, no post-quantum
+
+### ❌ Kubernetes Secrets
+- **Pros**: Built-in, simple
+- **Cons**: Almacenamiento by default sin encripción, no audit logging
+
+### ✅ SecretumVault (CHOSEN)
+- Post-quantum cryptography, Rust-native, audit-friendly
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Post-quantum resistance for future threats
+- ✅ Built-in audit logging of secret access
+- ✅ Rust-native (no external dependencies)
+- ✅ Encryption at-rest for API keys
+- ✅ Fine-grained access control
+
+**Cons**:
+- ⚠️ Smaller community than HashiCorp Vault
+- ⚠️ Fewer integrations with external tools
+- ⚠️ Post-quantum crypto adds computational overhead
+
+---
+
+## Implementation
+
+**Secret Storage**:
+```rust
+// crates/vapora-backend/src/secrets.rs
+use secretumvault::SecretStore;
+
+let secret_store = SecretStore::new()?;
+
+// Store API key with encryption
+secret_store.store_secret(
+    "anthropic_api_key",
+    "sk-ant-...",
+    SecretMetadata {
+        encrypted: true,
+        pq_algorithm: "ML-KEM-768",  // Post-quantum algorithm
+        owner: "llm-router",
+        created_at: Utc::now(),
+    }
+)?;
+```
+
+**Secret Retrieval**:
+```rust
+// Retrieve and decrypt
+let api_key = secret_store
+    .get_secret("anthropic_api_key")?
+    .decrypt()
+    .audit_log("anthropic_api_key_access", &user_id)?;
+```
+
+**Audit Log**:
+```rust
+// All secret operations logged
+secret_store.audit_log().query()
+    .secret("anthropic_api_key")
+    .since(Duration::days(1))
+    .await?
+    // Returns: Who accessed what secret when
+```
+
+**Configuration**:
+```toml
+# config/secrets.toml
+[secretumvault]
+store_path = "/etc/vapora/secrets.db"
+pq_algorithm = "ML-KEM-768"  # Post-quantum
+rotation_days = 90
+audit_retention_days = 365
+
+[[secret_categories]]
+name = "api_keys"
+encryption = true
+rotation_required = true
+
+[[secret_categories]]
+name = "database_credentials"
+encryption = true
+rotation_required = true
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/secrets.rs` (secret management)
+- `/crates/vapora-llm-router/src/providers.rs` (uses secrets to load API keys)
+- `/config/secrets.toml` (configuration)
+
+---
+
+## Verification
+
+```bash
+# Test secret storage and retrieval
+cargo test -p vapora-backend test_secret_storage
+
+# Test encryption/decryption
+cargo test -p vapora-backend test_secret_encryption
+
+# Verify audit logging
+cargo test -p vapora-backend test_audit_logging
+
+# Test key rotation
+cargo test -p vapora-backend test_secret_rotation
+
+# Verify post-quantum algorithms
+cargo test -p vapora-backend test_pq_algorithms
+
+# Integration test: load API key from secret store
+cargo test -p vapora-llm-router test_provider_auth -- --nocapture
+```
+
+**Expected Output**:
+- Secrets stored encrypted with post-quantum algorithm
+- Decryption works correctly
+- All secret access logged with timestamp, user, resource
+- Key rotation works automatically
+- API keys loaded securely in providers
+- No keys leak in logs or error messages
+
+---
+
+## Consequences
+
+### Security Operations
+- Secret rotation automated every 90 days
+- Audit logs accessible for compliance investigations
+- Break-glass procedures for emergency access (logged)
+- All secret operations require authentication
+
+### Performance
+- Secret retrieval cached (policies don't change)
+- Decryption overhead < 1ms per secret
+- Audit logging asynchronous (doesn't block requests)
+
+### Maintenance
+- Post-quantum algorithms updated as standards evolve
+- Audit logs must be retained per compliance policy
+- Key rotation scheduled and tracked
+
+### Compliance
+- Audit trail for regulatory investigations
+- Encryption meets security standards
+- Post-quantum protection for long-term security

+# ADR-012: Three-Tier LLM Routing (Rules + Dynamic + Override)
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: LLM Architecture Team
+**Technical Story**: Balancing predictability (static rules) with flexibility (dynamic selection) in provider routing
+
+---
+
+## Decision
+
+Implementar **three-tier routing system** para seleción de LLM providers: Rules → Dynamic → Override.
+
+---
+
+## Rationale
+
+1. **Rules-Based**: Predictable routing para tareas conocidas (Architecture → Claude Opus)
+2. **Dynamic**: Runtime selection basado en availability, latency, budget
+3. **Override**: Manual selection con audit logging para troubleshooting/testing
+4. **Balance**: Combinación de determinismo y flexibilidad
+
+---
+
+## Alternatives Considered
+
+### ❌ Static Rules Only
+- **Pros**: Predictable, simple
+- **Cons**: No adaptación a provider failures, no dynamic cost optimization
+
+### ❌ Dynamic Only
+- **Pros**: Flexible, adapts to runtime conditions
+- **Cons**: Unpredictable routing, harder to debug, cold-start problem
+
+### ✅ Three-Tier Hybrid (CHOSEN)
+- Predictable baseline + flexible adaptation + manual override
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Predictable baseline (rules)
+- ✅ Automatic adaptation (dynamic)
+- ✅ Manual control when needed (override)
+- ✅ Audit trail of decisions
+- ✅ Graceful degradation
+
+**Cons**:
+- ⚠️ Added complexity (3 selection layers)
+- ⚠️ Rule configuration maintenance
+- ⚠️ Override can introduce inconsistency if overused
+
+---
+
+## Implementation
+
+**Tier 1: Rules-Based Routing**:
+```rust
+// crates/vapora-llm-router/src/router.rs
+pub struct RoutingRules {
+    rules: Vec<(Pattern, ProviderId)>,
+}
+
+impl RoutingRules {
+    pub fn apply(&self, task: &Task) -> Option<ProviderId> {
+        for (pattern, provider) in &self.rules {
+            if pattern.matches(&task.description) {
+                return Some(provider.clone());
+            }
+        }
+        None
+    }
+}
+
+// Example rules
+let rules = vec![
+    (Pattern::contains("architecture"), "claude-opus"),
+    (Pattern::contains("code generation"), "gpt-4"),
+    (Pattern::contains("quick query"), "gemini-flash"),
+    (Pattern::contains("test"), "ollama"),
+];
+```
+
+**Tier 2: Dynamic Selection**:
+```rust
+pub async fn select_dynamic(
+    task: &Task,
+    providers: &[LLMClient],
+) -> Result<&LLMClient> {
+    // Score providers by: availability, latency, cost
+    let scores: Vec<(ProviderId, f64)> = providers
+        .iter()
+        .map(|p| {
+            let availability = check_availability(p).await;
+            let latency = estimate_latency(p).await;
+            let cost = get_cost_per_token(p);
+
+            let score = availability * 0.5
+                      - latency_penalty(latency) * 0.3
+                      - cost_penalty(cost) * 0.2;
+            (p.id.clone(), score)
+        })
+        .collect();
+
+    // Select highest scoring provider
+    scores
+        .into_iter()
+        .max_by(|a, b| a.1.partial_cmp(&b.1).unwrap())
+        .ok_or(Error::NoProvidersAvailable)
+}
+```
+
+**Tier 3: Manual Override**:
+```rust
+pub async fn route_task(
+    task: &Task,
+    override_provider: Option<ProviderId>,
+) -> Result<String> {
+    let provider_id = if let Some(override_id) = override_provider {
+        // Tier 3: Manual override (log for audit)
+        audit_log::log_override(&task.id, &override_id, &current_user())?;
+        override_id
+    } else if let Some(rule_provider) = apply_routing_rules(task) {
+        // Tier 1: Rules-based
+        rule_provider
+    } else {
+        // Tier 2: Dynamic selection
+        select_dynamic(task, &self.providers).await?.id.clone()
+    };
+
+    self.clients
+        .get(&provider_id)
+        .complete(&task.prompt)
+        .await
+}
+```
+
+**Configuration**:
+```toml
+# config/llm-routing.toml
+
+# Tier 1: Rules
+[[routing_rules]]
+pattern = "architecture"
+provider = "claude"
+model = "claude-opus"
+
+[[routing_rules]]
+pattern = "code_generation"
+provider = "openai"
+model = "gpt-4"
+
+[[routing_rules]]
+pattern = "quick_query"
+provider = "gemini"
+model = "gemini-flash"
+
+[[routing_rules]]
+pattern = "test"
+provider = "ollama"
+model = "llama2"
+
+# Tier 2: Dynamic scoring weights
+[dynamic_scoring]
+availability_weight = 0.5
+latency_weight = 0.3
+cost_weight = 0.2
+
+# Tier 3: Override audit settings
+[override_audit]
+log_all_overrides = true
+require_reason = true
+```
+
+**Key Files**:
+- `/crates/vapora-llm-router/src/router.rs` (routing logic)
+- `/crates/vapora-llm-router/src/config.rs` (rule definitions)
+- `/crates/vapora-backend/src/audit.rs` (override logging)
+
+---
+
+## Verification
+
+```bash
+# Test rules-based routing
+cargo test -p vapora-llm-router test_rules_routing
+
+# Test dynamic scoring
+cargo test -p vapora-llm-router test_dynamic_scoring
+
+# Test override with audit logging
+cargo test -p vapora-llm-router test_override_audit
+
+# Integration test: task routing through all tiers
+cargo test -p vapora-llm-router test_full_routing_pipeline
+
+# Verify audit trail
+cargo run -p vapora-backend -- audit query --type llm_override --limit 50
+```
+
+**Expected Output**:
+- Rules correctly match task patterns
+- Dynamic scoring selects best available provider
+- Overrides logged with user and reason
+- Fallback to next tier if previous fails
+- All three tiers functional and audited
+
+---
+
+## Consequences
+
+### Operational
+- Routing rules maintained in Git (versioned)
+- Dynamic scoring requires provider health checks
+- Overrides tracked in audit trail for compliance
+
+### Performance
+- Rule matching: O(n) patterns (pre-compiled for speed)
+- Dynamic scoring: Concurrent provider checks (~50ms)
+- Override bypasses both: immediate execution
+
+### Monitoring
+- Track which tier was used per request
+- Alert if dynamic tier used frequently (rules insufficient)
+- Report override usage patterns (identify gaps in rules)
+
+### Debugging
+- Audit trail shows exact routing decision
+- Reason recorded for overrides
+- Helps identify rule gaps or misconfiguration
+

+<ol>
+<li><strong>Collective Learning</strong>: Agentes aprenden de experiencia compartida (no solo individual)</li>
+<li><strong>Temporal History</strong>: Histórico de 30/90 días permite identificar tendencias</li>
+<li><strong>Causal Relationships</strong>: Graph permite rastrear raíces de problemas y soluciones</li>
+<li><strong>Similarity Search</strong>: Encontrar soluciones pasadas para tareas similares</li>

+# ADR-013: Knowledge Graph Temporal con SurrealDB
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Architecture Team
+**Technical Story**: Enabling collective agent learning through temporal execution history
+
+---
+
+## Decision
+
+Implementar **Knowledge Graph temporal** en SurrealDB con historia de ejecución, curvas de aprendizaje, y búsqueda de similaridad.
+
+---
+
+## Rationale
+
+1. **Collective Learning**: Agentes aprenden de experiencia compartida (no solo individual)
+2. **Temporal History**: Histórico de 30/90 días permite identificar tendencias
+3. **Causal Relationships**: Graph permite rastrear raíces de problemas y soluciones
+4. **Similarity Search**: Encontrar soluciones pasadas para tareas similares
+5. **SurrealDB Native**: Graph queries integradas en mismo DB que relacional
+
+---
+
+## Alternatives Considered
+
+### ❌ Event Log Only (No Graph)
+- **Pros**: Simple
+- **Cons**: Sin relaciones causales, búsqueda ineficiente
+
+### ❌ Separate Graph DB (Neo4j)
+- **Pros**: Optimizado para graph
+- **Cons**: Duplicación de datos, sincronización complexity
+
+### ✅ SurrealDB Temporal KG (CHOSEN)
+- Unificado, temporal, graph queries integradas
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Temporal data (30/90 day retention)
+- ✅ Causal relationships traceable
+- ✅ Similarity search for solution discovery
+- ✅ Learning curves identify improvement trends
+- ✅ Single database (no sync issues)
+
+**Cons**:
+- ⚠️ Graph queries more complex than relational
+- ⚠️ Storage overhead for full history
+- ⚠️ Retention policy trade-off: longer history = more storage
+
+---
+
+## Implementation
+
+**Temporal Data Model**:
+```rust
+// crates/vapora-knowledge-graph/src/models.rs
+pub struct ExecutionRecord {
+    pub id: String,
+    pub agent_id: String,
+    pub task_id: String,
+    pub task_type: String,
+    pub success: bool,
+    pub quality_score: f32,
+    pub latency_ms: u32,
+    pub cost_cents: u32,
+    pub timestamp: DateTime<Utc>,
+    pub daily_window: String,  // YYYY-MM-DD for aggregation
+}
+
+pub struct LearningCurve {
+    pub id: String,
+    pub agent_id: String,
+    pub task_type: String,
+    pub day: String,           // YYYY-MM-DD
+    pub success_rate: f32,
+    pub avg_quality: f32,
+    pub trend: TrendDirection, // Improving, Stable, Declining
+}
+```
+
+**SurrealDB Schema**:
+```surql
+-- Define execution records table
+DEFINE TABLE executions;
+DEFINE FIELD agent_id ON TABLE executions TYPE string;
+DEFINE FIELD task_id ON TABLE executions TYPE string;
+DEFINE FIELD task_type ON TABLE executions TYPE string;
+DEFINE FIELD success ON TABLE executions TYPE boolean;
+DEFINE FIELD quality_score ON TABLE executions TYPE float;
+DEFINE FIELD timestamp ON TABLE executions TYPE datetime;
+DEFINE FIELD daily_window ON TABLE executions TYPE string;
+
+-- Define temporal index for efficient time-range queries
+DEFINE INDEX idx_execution_temporal ON TABLE executions
+    COLUMNS timestamp, daily_window;
+
+-- Define learning curves table
+DEFINE TABLE learning_curves;
+DEFINE FIELD agent_id ON TABLE learning_curves TYPE string;
+DEFINE FIELD task_type ON TABLE learning_curves TYPE string;
+DEFINE FIELD day ON TABLE learning_curves TYPE string;
+DEFINE FIELD success_rate ON TABLE learning_curves TYPE float;
+DEFINE FIELD trend ON TABLE learning_curves TYPE string;
+```
+
+**Temporal Query (30-Day Learning Curve)**:
+```rust
+// crates/vapora-knowledge-graph/src/learning.rs
+pub async fn compute_learning_curve(
+    db: &Surreal<Ws>,
+    agent_id: &str,
+    task_type: &str,
+    days: u32,
+) -> Result<Vec<LearningCurve>> {
+    let since = (Utc::now() - Duration::days(days as i64))
+        .format("%Y-%m-%d")
+        .to_string();
+
+    let query = format!(
+        r#"
+        SELECT
+            day,
+            count(id) as total_tasks,
+            count(id WHERE success = true) / count(id) as success_rate,
+            avg(quality_score) as avg_quality,
+            (avg(quality_score) - LAG(avg(quality_score)) OVER (ORDER BY day)) as trend
+        FROM executions
+        WHERE agent_id = {} AND task_type = {} AND daily_window >= {}
+        GROUP BY daily_window
+        ORDER BY daily_window ASC
+        "#,
+        agent_id, task_type, since
+    );
+
+    db.query(query).await?
+        .take::<Vec<LearningCurve>>(0)?
+        .ok_or(Error::NotFound)
+}
+```
+
+**Similarity Search (Find Past Solutions)**:
+```rust
+pub async fn find_similar_tasks(
+    db: &Surreal<Ws>,
+    task: &Task,
+    limit: u32,
+) -> Result<Vec<(ExecutionRecord, f32)>> {
+    // Compute embedding similarity for task description
+    let similarity_threshold = 0.85;
+
+    let query = r#"
+        SELECT
+            executions.*,
+            <similarity_score> as score
+        FROM executions
+        WHERE similarity_score > {} AND success = true
+        ORDER BY similarity_score DESC
+        LIMIT {}
+    "#;
+
+    db.query(query)
+        .bind(("similarity_score", similarity_threshold))
+        .bind(("limit", limit))
+        .await?
+        .take::<Vec<(ExecutionRecord, f32)>>(0)?
+        .ok_or(Error::NotFound)
+}
+```
+
+**Causal Graph (Problem Resolution)**:
+```rust
+pub async fn trace_solution_chain(
+    db: &Surreal<Ws>,
+    problem_task_id: &str,
+) -> Result<Vec<ExecutionRecord>> {
+    let query = format!(
+        r#"
+        SELECT
+            ->(resolved_by)->executions AS solutions
+        FROM tasks
+        WHERE id = {}
+        "#,
+        problem_task_id
+    );
+
+    db.query(query)
+        .await?
+        .take::<Vec<ExecutionRecord>>(0)?
+        .ok_or(Error::NotFound)
+}
+```
+
+**Key Files**:
+- `/crates/vapora-knowledge-graph/src/learning.rs` (learning curve computation)
+- `/crates/vapora-knowledge-graph/src/persistence.rs` (DB persistence)
+- `/crates/vapora-knowledge-graph/src/models.rs` (temporal models)
+- `/crates/vapora-backend/src/services/` (uses KG for task recommendations)
+
+---
+
+## Verification
+
+```bash
+# Test learning curve computation
+cargo test -p vapora-knowledge-graph test_learning_curve_30day
+
+# Test similarity search
+cargo test -p vapora-knowledge-graph test_similarity_search
+
+# Test causal graph traversal
+cargo test -p vapora-knowledge-graph test_causal_chain
+
+# Test retention policy (30-day window)
+cargo test -p vapora-knowledge-graph test_retention_policy
+
+# Integration test: full KG workflow
+cargo test -p vapora-knowledge-graph test_full_kg_lifecycle
+
+# Query performance test
+cargo bench -p vapora-knowledge-graph bench_temporal_queries
+```
+
+**Expected Output**:
+- Learning curves computed correctly
+- Similarity search finds relevant past executions
+- Causal chains traceable
+- Retention policy removes old records
+- Temporal queries perform well (<100ms)
+
+---
+
+## Consequences
+
+### Data Management
+- Storage grows ~1MB per 1000 executions (depends on detail level)
+- Retention policy: 30 days (users), 90 days (enterprise)
+- Archival strategy for historical analysis
+
+### Agent Learning
+- Agents access KG to find similar past solutions
+- Learning curves inform agent selection (see ADR-014)
+- Improvement trends visible for monitoring
+
+### Observability
+- Full audit trail of agent decisions
+- Trending analysis for capacity planning
+- Incident investigation via causal chains
+
+### Scalability
+- Graph queries optimized with indexes
+- Temporal queries use daily windows (efficient partition)
+- Similarity search scales to millions of records
+
+---

+# ADR-014: Learning Profiles con Recency Bias
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Agent Architecture Team
+**Technical Story**: Tracking per-task-type agent expertise with recency-weighted learning
+
+---
+
+## Decision
+
+Implementar **Learning Profiles per-task-type con exponential recency bias** para adaptar selección de agentes a capacidad actual.
+
+---
+
+## Rationale
+
+1. **Recency Bias**: Últimos 7 días pesados 3× más alto (agentes mejoran rápidamente)
+2. **Per-Task-Type**: Un perfil por tipo de tarea (architecture vs code gen vs review)
+3. **Avoid Stale Data**: No usar promedio histórico (puede estar desactualizado)
+4. **Confidence Score**: Requiere 20+ ejecuciones antes de confianza completa
+
+---
+
+## Alternatives Considered
+
+### ❌ Simple Average (All-Time)
+- **Pros**: Simple
+- **Cons**: Histórico antiguo distorsiona, no adapta a mejoras actuales
+
+### ❌ Sliding Window (Last N Executions)
+- **Pros**: More recent data
+- **Cons**: Artificial cutoff, perder contexto histórico
+
+### ✅ Exponential Recency Bias (CHOSEN)
+- Pesa natural según antigüedad, mejor refleja capacidad actual
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Adapts to agent capability improvements quickly
+- ✅ Exponential decay is mathematically sound
+- ✅ 20+ execution confidence threshold prevents overfitting
+- ✅ Per-task-type specialization
+
+**Cons**:
+- ⚠️ Cold-start: new agents start with low confidence
+- ⚠️ Requires 20 executions to reach full confidence
+- ⚠️ Storage overhead (per agent × per task type)
+
+---
+
+## Implementation
+
+**Learning Profile Model**:

+
+impl TaskTypeLearning {
+    /// Recency weight formula: 3.0 * e^(-days_ago / 7.0) for recent

+                let weight = Self::compute_recency_weight(days_ago);
+                (r.quality_score as f64) * weight
+            })
+            .sum();

+            .map(|r| {
+                let days_ago = (now - r.timestamp).num_days() as f64;
+                Self::compute_recency_weight(days_ago)
+            })
+            .sum();
+
+        (weighted_sum / weight_sum) as f32
+    }
+
+    /// Confidence score: min(1.0, executions / 20)
+    pub fn confidence(&self) -> f32 {
+        std::cmp::min(1.0, (self.executions_total as f32) / 20.0)
+    }
+
+    /// Final score combines expertise × confidence
+    pub fn score(&self) -> f32 {
+        self.expertise_score() * self.confidence()
+    }
+}
+```
+
+**Recording Execution**:
+```rust
+pub async fn record_execution(
+    db: &Surreal<Ws>,
+    agent_id: &str,
+    task_type: &str,
+    success: bool,
+    quality: f32,
+) -> Result<()> {
+    let record = ExecutionRecord {
+        agent_id: agent_id.to_string(),
+        task_type: task_type.to_string(),
+        success,
+        quality_score: quality,
+        timestamp: Utc::now(),
+    };
+
+    // Store in KG
+    db.create("executions").content(&record).await?;
+
+    // Update learning profile
+    let profile = db.query(
+        "SELECT * FROM task_type_learning \
+         WHERE agent_id = $1 AND task_type = $2"
+    )
+    .bind((agent_id, task_type))
+    .await?;
+
+    // Update counters (incremental)
+    // If new profile, create with initial values
+    Ok(())
+}
+```
+
+**Agent Selection Using Profiles**:
+```rust
+pub async fn select_agent_for_task(
+    db: &Surreal<Ws>,
+    task_type: &str,
+) -> Result<AgentId> {
+    let profiles = db.query(
+        "SELECT agent_id, expertise_score(), confidence(), score() \
+         FROM task_type_learning \
+         WHERE task_type = $1 \
+         ORDER BY score() DESC \
+         LIMIT 1"
+    )
+    .bind(task_type)
+    .await?;
+
+    let best_agent = profiles
+        .take::<TaskTypeLearning>(0)?
+        .ok_or(Error::NoAgentsAvailable)?;
+
+    Ok(best_agent.agent_id)
+}
+```
+
+**Scoring Formula**:
+```
+expertise_score = Σ(quality_score_i × recency_weight_i) / Σ(recency_weight_i)
+recency_weight_i = {
+    3.0 × e^(-days_ago / 7.0)  if days_ago ≤ 7 days  (3× recent bias)
+    e^(-days_ago / 7.0)         if days_ago > 7 days  (exponential decay)
+}
+confidence = min(1.0, total_executions / 20)
+final_score = expertise_score × confidence
+```
+
+**Key Files**:
+- `/crates/vapora-agents/src/learning_profile.rs` (profile computation)
+- `/crates/vapora-agents/src/scoring.rs` (score calculations)
+- `/crates/vapora-agents/src/selector.rs` (agent selection logic)
+
+---
+
+## Verification
+
+```bash
+# Test recency weight calculation
+cargo test -p vapora-agents test_recency_weight
+
+# Test expertise score with mixed recent/old executions
+cargo test -p vapora-agents test_expertise_score
+
+# Test confidence with <20 and >20 executions
+cargo test -p vapora-agents test_confidence_score
+
+# Integration: record executions and verify profile updates
+cargo test -p vapora-agents test_profile_recording
+
+# Integration: select best agent using profiles
+cargo test -p vapora-agents test_agent_selection_by_profile
+
+# Verify cold-start (new agent has low score)
+cargo test -p vapora-agents test_cold_start_bias
+```
+
+**Expected Output**:
+- Recent executions (< 7 days) weighted 3× higher
+- Older executions gradually decay exponentially
+- New agents (< 20 executions) have lower confidence
+- Agents with 20+ executions reach full confidence
+- Best agent selected based on recency-weighted score
+- Profile updates recorded in KG
+
+---
+
+## Consequences
+
+### Agent Dynamics
+- Agents that improve rapidly rise in selection order
+- Poor-performing agents decline even with historical success
+- Learning profiles encourage agent improvement (recent success rewarded)
+
+### Data Management
+- One profile per agent × per task type
+- Last 100 executions per profile retained (rest in archive)
+- Storage: ~50KB per profile
+
+### Monitoring
+- Track which agents are trending up/down
+- Identify agents with cold-start problem
+- Alert if all agents for task type below threshold
+
+### User Experience
+- Best agents selected automatically
+- Selection adapts to agent improvements
+- Users see faster task completion over time

+<p>Implementar <strong>three-tier budget enforcement</strong> con dual time windows (monthly + weekly) y automatic fallback a Ollama.</p>
+<hr />
+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Dual Windows</strong>: Previene tanto overspend a largo plazo (monthly) como picos (weekly)</li>
+<li><strong>Three States</strong>: Normal → Near-threshold → Exceeded (progressive restriction)</li>
+<li><strong>Auto-Fallback</strong>: Usar Ollama ($0) cuando budget exceeded (graceful degradation)</li>
+<li><strong>Per-Role Limits</strong>: Budget distinto por rol (arquitecto vs developer vs reviewer)</li>
+</ol>

+<h2 id="alternatives-considered"><a class="header" href="#alternatives-considered">Alternatives Considered</a></h2>
+<h3 id="-monthly-only"><a class="header" href="#-monthly-only">❌ Monthly Only</a></h3>
+<ul>

+<h3 id="-weekly-only"><a class="header" href="#-weekly-only">❌ Weekly Only</a></h3>

+<p><strong>Pros</strong>:</p>
+<ul>
+<li>✅ Protection against both spike and gradual overspend</li>
+<li>✅ Progressive alerts (normal → near → exceeded)</li>
+<li>✅ Automatic fallback prevents hard stops</li>
+<li>✅ Per-role customization</li>
+<li>✅ Quality degrades gracefully</li>
+</ul>
+<p><strong>Cons</strong>:</p>
+<ul>
+<li>⚠️ Alert fatigue possible if thresholds set too tight</li>

+# ADR-015: Three-Tier Budget Enforcement con Auto-Fallback
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Cost Architecture Team
+**Technical Story**: Preventing LLM spend overruns with dual time windows and graceful degradation
+
+---
+
+## Decision
+
+Implementar **three-tier budget enforcement** con dual time windows (monthly + weekly) y automatic fallback a Ollama.
+
+---
+
+## Rationale
+
+1. **Dual Windows**: Previene tanto overspend a largo plazo (monthly) como picos (weekly)
+2. **Three States**: Normal → Near-threshold → Exceeded (progressive restriction)
+3. **Auto-Fallback**: Usar Ollama ($0) cuando budget exceeded (graceful degradation)
+4. **Per-Role Limits**: Budget distinto por rol (arquitecto vs developer vs reviewer)
+
+---
+
+## Alternatives Considered
+
+### ❌ Monthly Only
+- **Pros**: Simple
+- **Cons**: Allow weekly spikes, late-month overspend
+
+### ❌ Weekly Only
+- **Pros**: Catches spikes
+- **Cons**: No protection for slow bleed, fragmented budget
+
+### ✅ Dual Windows + Auto-Fallback (CHOSEN)
+- Protege contra ambos spikes y long-term overspend
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Protection against both spike and gradual overspend
+- ✅ Progressive alerts (normal → near → exceeded)
+- ✅ Automatic fallback prevents hard stops
+- ✅ Per-role customization
+- ✅ Quality degrades gracefully
+
+**Cons**:
+- ⚠️ Alert fatigue possible if thresholds set too tight
+- ⚠️ Fallback to Ollama may reduce quality
+- ⚠️ Configuration complexity (two threshold sets)
+
+---
+
+## Implementation
+
+**Budget Configuration**:
+```toml
+# config/budget.toml
+
+[[role_budgets]]
+role = "architect"
+monthly_budget_usd = 1000
+weekly_budget_usd = 250
+
+[[role_budgets]]
+role = "developer"
+monthly_budget_usd = 500
+weekly_budget_usd = 125
+
+[[role_budgets]]
+role = "reviewer"
+monthly_budget_usd = 200
+weekly_budget_usd = 50
+
+# Enforcement thresholds
+[enforcement]
+normal_threshold = 0.80       # < 80%: Use optimal provider
+near_threshold = 1.0          # 80-100%: Cheaper providers
+exceeded_threshold = 1.0      # > 100%: Fallback to Ollama
+
+[alerts]
+near_threshold_alert = true
+exceeded_alert = true
+alert_channels = ["slack", "email"]
+```
+
+**Budget Tracking Model**:
+```rust
+// crates/vapora-llm-router/src/budget.rs
+pub struct BudgetState {
+    pub role: String,
+    pub monthly_spent_cents: u32,
+    pub monthly_budget_cents: u32,
+    pub weekly_spent_cents: u32,
+    pub weekly_budget_cents: u32,
+    pub last_reset_week: Week,
+}
+
+#[derive(Debug, Clone, Copy, PartialEq, Eq)]
+pub enum EnforcementState {
+    Normal,           // < 80%: Use optimal provider
+    NearThreshold,    // 80-100%: Prefer cheaper
+    Exceeded,         // > 100%: Fallback to Ollama
+}
+
+impl BudgetState {
+    pub fn monthly_percentage(&self) -> f32 {
+        (self.monthly_spent_cents as f32) / (self.monthly_budget_cents as f32)
+    }
+
+    pub fn weekly_percentage(&self) -> f32 {
+        (self.weekly_spent_cents as f32) / (self.weekly_budget_cents as f32)
+    }
+
+    pub fn enforcement_state(&self) -> EnforcementState {
+        let monthly_pct = self.monthly_percentage();
+        let weekly_pct = self.weekly_percentage();
+
+        // Use more restrictive of two
+        let most_restrictive = monthly_pct.max(weekly_pct);
+
+        if most_restrictive < 0.80 {
+            EnforcementState::Normal
+        } else if most_restrictive < 1.0 {
+            EnforcementState::NearThreshold
+        } else {
+            EnforcementState::Exceeded
+        }
+    }
+}
+```
+
+**Budget Enforcement in Router**:
+```rust
+pub async fn route_with_budget(
+    task: &Task,
+    user_role: &str,
+    budget_state: &mut BudgetState,
+) -> Result<String> {
+    // Check budget state
+    let enforcement = budget_state.enforcement_state();
+
+    match enforcement {
+        EnforcementState::Normal => {
+            // Use optimal provider (Claude, GPT-4)
+            let provider = select_optimal_provider(task).await?;
+            execute_with_provider(task, &provider, budget_state).await
+        }
+        EnforcementState::NearThreshold => {
+            // Alert user, prefer cheaper providers
+            alert_near_threshold(user_role, budget_state)?;
+            let provider = select_cheap_provider(task).await?;
+            execute_with_provider(task, &provider, budget_state).await
+        }
+        EnforcementState::Exceeded => {
+            // Alert, fallback to Ollama
+            alert_exceeded(user_role, budget_state)?;
+            let provider = "ollama"; // Free
+            execute_with_provider(task, provider, budget_state).await
+        }
+    }
+}
+
+async fn execute_with_provider(
+    task: &Task,
+    provider: &str,
+    budget_state: &mut BudgetState,
+) -> Result<String> {
+    let response = call_provider(task, provider).await?;
+    let cost_cents = estimate_cost(&response, provider)?;
+
+    // Update budget
+    budget_state.monthly_spent_cents += cost_cents;
+    budget_state.weekly_spent_cents += cost_cents;
+
+    // Log for audit
+    log_budget_usage(task.id, provider, cost_cents)?;
+
+    Ok(response)
+}
+```
+
+**Reset Logic**:
+```rust
+pub async fn reset_budget_weekly(db: &Surreal<Ws>) -> Result<()> {
+    let now = Utc::now();
+    let current_week = week_number(now);
+
+    let budgets = db.query(
+        "SELECT * FROM role_budgets WHERE last_reset_week < $1"
+    )
+    .bind(current_week)
+    .await?;
+
+    for mut budget in budgets {
+        budget.weekly_spent_cents = 0;
+        budget.last_reset_week = current_week;
+        db.update(&budget.id).content(&budget).await?;
+    }
+
+    Ok(())
+}
+```

+
+## Verification
+
+```bash
+# Test budget percentage calculation
+cargo test -p vapora-llm-router test_budget_percentage
+
+# Test enforcement states
+cargo test -p vapora-llm-router test_enforcement_states
+
+# Test normal → near-threshold transition
+cargo test -p vapora-llm-router test_near_threshold_alert
+
+# Test exceeded → fallback to Ollama
+cargo test -p vapora-llm-router test_budget_exceeded_fallback
+
+# Test weekly reset
+cargo test -p vapora-llm-router test_weekly_budget_reset
+
+# Integration: full budget lifecycle
+cargo test -p vapora-llm-router test_budget_full_cycle
+```
+
+**Expected Output**:
+- Budget percentages calculated correctly
+- Enforcement state transitions as budget fills
+- Near-threshold alerts triggered at 80%
+- Fallback to Ollama when exceeded 100%
+- Weekly reset clears weekly budget
+- Monthly budget accumulates across weeks
+- All transitions logged for audit
+
+---
+
+## Consequences
+
+### Financial
+- Predictable monthly costs (bounded by monthly_budget)
+- Alert on near-threshold prevents surprises
+- Auto-fallback protects against runaway spend
+
+### User Experience
+- Quality degrades gracefully (not hard stop)
+- Users can continue working (Ollama fallback)
+- Alerts notify of budget status
+
+### Operations
+- Budget resets automated (weekly)
+- Per-role customization allows differentiation
+- Cost reports broken down by role
+
+### Monitoring
+- Track which roles consuming most budget
+- Identify unusual spend patterns
+- Forecast end-of-month spend

+# ADR-016: Cost Efficiency Ranking Algorithm
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Cost Architecture Team
+**Technical Story**: Ranking LLM providers by quality-to-cost ratio to prevent cost overfitting
+
+---
+
+## Decision
+
+Implementar **Cost Efficiency Ranking** con fórmula `efficiency = (quality_score * 100) / (cost_cents + 1)`.
+
+---
+
+## Rationale
+
+1. **Prevents Cost Overfitting**: No preferir siempre provider más barato (quality importa)
+2. **Balances Quality and Cost**: Fórmula explícita que combina ambas dimensiones
+3. **Handles Zero-Cost**: `+ 1` evita division-by-zero para Ollama ($0)
+4. **Normalized Scale**: Scores comparables entre providers
+
+---
+
+## Alternatives Considered
+
+### ❌ Quality Only (Ignore Cost)
+- **Pros**: Highest quality
+- **Cons**: Unbounded costs
+
+### ❌ Cost Only (Ignore Quality)
+- **Pros**: Lowest cost
+- **Cons**: Poor quality results
+
+### ✅ Quality/Cost Ratio (CHOSEN)
+- Balances both dimensions mathematically
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Single metric for comparison
+- ✅ Prevents cost overfitting
+- ✅ Prevents quality overfitting
+- ✅ Handles zero-cost providers
+- ✅ Easy to understand and explain
+
+**Cons**:
+- ⚠️ Formula is simplified (assumes linear quality/cost)
+- ⚠️ Quality scores must be comparable across providers
+- ⚠️ May not capture all cost factors (latency, tokens)
+
+---
+
+## Implementation
+

+
+**Cost Efficiency Calculation**:
+```rust
+pub struct CostEfficiency {
+    provider: String,
+    quality_score: f32,
+    cost_cents: u32,
+    efficiency_score: f32,
+}
+
+impl CostEfficiency {
+    pub fn calculate(
+        provider: &str,
+        quality: f32,
+        cost_cents: u32,
+    ) -> f32 {
+        (quality * 100.0) / ((cost_cents as f32) + 1.0)
+    }
+
+    pub fn from_provider(
+        provider: &str,
+        quality: f32,
+        cost_cents: u32,
+    ) -> Self {
+        let efficiency = Self::calculate(provider, quality, cost_cents);
+
+        Self {
+            provider: provider.to_string(),
+            quality_score: quality,
+            cost_cents,
+            efficiency_score: efficiency,
+        }
+    }
+}
+
+// Examples:
+// Claude Opus: quality=0.95, cost=50¢ → efficiency = (0.95*100)/(50+1) = 1.86
+// GPT-4:       quality=0.92, cost=30¢ → efficiency = (0.92*100)/(30+1) = 2.97
+// Gemini:      quality=0.88, cost=5¢  → efficiency = (0.88*100)/(5+1) = 14.67
+// Ollama:      quality=0.75, cost=0¢  → efficiency = (0.75*100)/(0+1) = 75.0
+```
+
+**Ranking by Efficiency**:
+```rust
+pub async fn rank_providers_by_efficiency(
+    providers: &[LLMClient],
+    task_type: &str,
+) -> Result<Vec<(String, f32)>> {
+    let mut efficiencies = Vec::new();
+
+    for provider in providers {
+        let quality = get_quality_for_task(&provider.id, task_type)?;
+        let cost_per_token = provider.cost_per_token();
+        let estimated_tokens = estimate_tokens_for_task(task_type);
+        let total_cost_cents = (cost_per_token * estimated_tokens as f64) as u32;
+
+        let efficiency = CostEfficiency::calculate(
+            &provider.id,
+            quality,
+            total_cost_cents,
+        );
+
+        efficiencies.push((provider.id.clone(), efficiency));
+    }
+
+    // Sort by efficiency descending
+    efficiencies.sort_by(|a, b| {
+        b.1.partial_cmp(&a.1).unwrap_or(std::cmp::Ordering::Equal)
+    });
+
+    Ok(efficiencies)
+}
+```
+
+**Provider Selection with Efficiency**:
+```rust
+pub async fn select_best_provider_by_efficiency(
+    task: &Task,
+    available_providers: &[LLMClient],
+) -> Result<&'_ LLMClient> {
+    let ranked = rank_providers_by_efficiency(available_providers, &task.task_type).await?;
+
+    // Return highest efficiency
+    ranked
+        .first()
+        .and_then(|(provider_id, _)| {
+            available_providers.iter().find(|p| p.id == *provider_id)
+        })
+        .ok_or(Error::NoProvidersAvailable)
+}
+```
+
+**Efficiency Metrics**:
+```rust
+pub async fn report_efficiency(
+    db: &Surreal<Ws>,
+) -> Result<String> {
+    // Query: execution history with cost and quality
+    let query = r#"
+        SELECT
+            provider,
+            avg(quality_score) as avg_quality,
+            avg(cost_cents) as avg_cost,
+            (avg(quality_score) * 100) / (avg(cost_cents) + 1) as avg_efficiency
+        FROM executions
+        WHERE timestamp > now() - 1d  -- Last 24 hours
+        GROUP BY provider
+        ORDER BY avg_efficiency DESC
+    "#;
+
+    let results = db.query(query).await?;
+    Ok(format_efficiency_report(results))
+}
+```

+**Key Files**:
+- `/crates/vapora-llm-router/src/cost_ranker.rs` (efficiency calculations)

+
+## Verification
+
+```bash
+# Test efficiency calculation with various costs
+cargo test -p vapora-llm-router test_cost_efficiency_calculation
+
+# Test zero-cost handling (Ollama)
+cargo test -p vapora-llm-router test_zero_cost_efficiency
+
+# Test provider ranking by efficiency
+cargo test -p vapora-llm-router test_provider_ranking_efficiency
+
+# Test efficiency comparison across providers
+cargo test -p vapora-llm-router test_efficiency_comparison
+
+# Integration: select best provider by efficiency
+cargo test -p vapora-llm-router test_select_by_efficiency
+```
+
+**Expected Output**:
+- Claude Opus ranked well despite higher cost (quality offset)
+- Ollama ranked very high (zero cost, decent quality)
+- Gemini ranked between (good efficiency)
+- GPT-4 ranked based on balanced cost/quality
+- Rankings consistent across multiple runs
+
+---
+
+## Consequences
+
+### Cost Optimization
+- Prevents pure cost minimization (quality matters)
+- Prevents pure quality maximization (cost matters)
+- Balanced strategy emerges
+
+### Provider Selection
+- No single provider always selected (depends on task)
+- Ollama used frequently (high efficiency)
+- Premium providers used for high-quality tasks only
+
+### Reporting
+- Efficiency metrics tracked over time
+- Identify providers underperforming cost-wise
+- Guide budget allocation
+
+### Monitoring
+- Alert if efficiency drops for any provider
+- Track efficiency trends
+- Recommend provider switches if efficiency improves

+# ADR-017: Confidence Weighting en Learning Profiles
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Agent Architecture Team
+**Technical Story**: Preventing new agents from being preferred on lucky first runs
+
+---
+
+## Decision
+
+Implementar **Confidence Weighting** con fórmula `confidence = min(1.0, total_executions / 20)`.
+
+---
+
+## Rationale
+
+1. **Prevents Overfitting**: Agentes nuevos con 1 éxito no deben ser preferred
+2. **Statistical Significance**: 20 ejecuciones proporciona confianza estadística
+3. **Gradual Increase**: Confianza sube mientras agente ejecuta más tareas
+4. **Prevents Lucky Streaks**: Requiere evidencia antes de preferencia
+
+---
+
+## Alternatives Considered
+
+### ❌ No Confidence Weighting
+- **Pros**: Simple
+- **Cons**: New agent with 1 success could be selected
+
+### ❌ Higher Threshold (e.g., 50 executions)
+- **Pros**: More statistical rigor
+- **Cons**: Cold-start problem worse, new agents never selected
+
+### ✅ Confidence = min(1.0, executions/20) (CHOSEN)
+- Reasonable threshold, balances learning and avoiding lucky streaks
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Prevents overfitting on single success
+- ✅ Reasonable learning curve (20 executions)
+- ✅ Simple formula
+- ✅ Transparent and explainable
+
+**Cons**:
+- ⚠️ Cold-start: new agents take 20 runs to full confidence
+- ⚠️ Not adaptive (same threshold for all task types)
+- ⚠️ May still allow lucky streaks (before 20 runs)
+
+---
+
+## Implementation
+
+**Confidence Model**:
+```rust
+// crates/vapora-agents/src/learning_profile.rs
+
+impl TaskTypeLearning {
+    /// Confidence score: how much to trust this agent's score
+    /// min(1.0, executions / 20) = 0.05 at 1 execution, 1.0 at 20+
+    pub fn confidence(&self) -> f32 {
+        std::cmp::min(
+            1.0,
+            (self.executions_total as f32) / 20.0
+        )
+    }
+
+    /// Adjusted score: expertise * confidence
+    /// Even with perfect expertise, low confidence reduces score
+    pub fn adjusted_score(&self) -> f32 {
+        let expertise = self.expertise_score();
+        let confidence = self.confidence();
+        expertise * confidence
+    }
+
+    /// Confidence progression examples:
+    /// 1 exec:  confidence = 0.05 (5%)
+    /// 5 exec:  confidence = 0.25 (25%)
+    /// 10 exec: confidence = 0.50 (50%)
+    /// 20 exec: confidence = 1.0 (100%)
+}
+```
+
+**Agent Selection with Confidence**:
+```rust
+pub async fn select_best_agent_with_confidence(
+    db: &Surreal<Ws>,
+    task_type: &str,
+) -> Result<String> {
+    // Query all agents for this task type
+    let profiles = db.query(
+        "SELECT agent_id, executions_total, expertise_score(), confidence() \
+         FROM task_type_learning \
+         WHERE task_type = $1 \
+         ORDER BY (expertise_score * confidence) DESC \
+         LIMIT 5"
+    )
+    .bind(task_type)
+    .await?;
+
+    let best = profiles
+        .take::<TaskTypeLearning>(0)?
+        .first()
+        .ok_or(Error::NoAgentsAvailable)?;
+
+    // Log selection with confidence for debugging
+    tracing::info!(
+        "Selected agent {} with confidence {:.2}% (after {} executions)",
+        best.agent_id,
+        best.confidence() * 100.0,
+        best.executions_total
+    );
+
+    Ok(best.agent_id.clone())
+}
+```
+
+**Preventing Lucky Streaks**:
+```rust
+// Example: Agent with 1 success but 5% confidence
+let agent_1_success = TaskTypeLearning {
+    agent_id: "new-agent-1".to_string(),
+    task_type: "code_generation".to_string(),
+    executions_total: 1,
+    executions_successful: 1,
+    avg_quality_score: 0.95,  // Perfect on first try!
+    records: vec![ExecutionRecord { /* ... */ }],
+};
+
+// Expertise would be 0.95, but confidence is only 0.05
+let score = agent_1_success.adjusted_score();  // 0.95 * 0.05 = 0.0475
+// This agent scores much lower than established agent with 0.80 expertise, 0.50 confidence
+// 0.80 * 0.50 = 0.40 > 0.0475
+
+// Agent needs ~20 successes before reaching full confidence
+let agent_20_success = TaskTypeLearning {
+    executions_total: 20,
+    executions_successful: 20,
+    avg_quality_score: 0.95,
+    /* ... */
+};
+
+let score = agent_20_success.adjusted_score();  // 0.95 * 1.0 = 0.95
+```
+
+**Confidence Visualization**:
+```rust
+pub fn confidence_ramp() -> Vec<(u32, f32)> {
+    (0..=40)
+        .map(|execs| {
+            let confidence = std::cmp::min(1.0, (execs as f32) / 20.0);
+            (execs, confidence)
+        })
+        .collect()
+}
+
+// Output:
+// 0 execs:  0.00
+// 1 exec:   0.05
+// 2 execs:  0.10
+// 5 execs:  0.25
+// 10 execs: 0.50
+// 20 execs: 1.00  ← Full confidence reached
+// 30 execs: 1.00  ← Capped at 1.0
+// 40 execs: 1.00  ← Still capped

+
+**Expected Output**:

+- 5 executions: confidence = 0.25 (25%)
+- 10 executions: confidence = 0.50 (50%)
+- 20 executions: confidence = 1.0 (100%)
+- New agent with 1 success not selected over established agent
+- Confidence gradually increases as agent executes more
+- Adjusted score properly combines expertise and confidence

+
+## Consequences
+
+### Agent Cold-Start
+- New agents require ~20 successful executions before reaching full score
+- Longer ramp-up but prevents bad deployments
+- Users understand why new agents aren't immediately selected
+
+### Agent Ranking
+- Established agents (20+ executions) ranked by expertise only
+- Developing agents (< 20 executions) ranked by expertise * confidence
+- Creates natural progression for agent improvement
+
+### Learning Curve
+- First 20 executions critical for agent adoption
+- After 20, confidence no longer a limiting factor
+- Encourages testing new agents early
+
+### Monitoring
+- Track which agents reach 20 executions
+- Identify agents stuck below 20 (poor performance)
+- Celebrate agents reaching full confidence

+<hr />
+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Success Rate</strong>: Seleccionar agentes que han tenido éxito en tareas similares</li>
+<li><strong>Load Factor</strong>: Balancear entre expertise y disponibilidad (no sobrecargar)</li>
+<li><strong>Single Formula</strong>: Combina ambas dimensiones en una métrica comparable</li>
+<li><strong>Prevents Concentration</strong>: Evitar que todos los tasks vayan a un solo agent</li>

+# ADR-018: Swarm Load-Balanced Task Assignment
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Swarm Coordination Team
+**Technical Story**: Distributing tasks across agents considering both capability and current load
+
+---
+
+## Decision
+
+Implementar **load-balanced task assignment** con fórmula `assignment_score = success_rate / (1 + load)`.
+
+---
+
+## Rationale
+
+1. **Success Rate**: Seleccionar agentes que han tenido éxito en tareas similares
+2. **Load Factor**: Balancear entre expertise y disponibilidad (no sobrecargar)
+3. **Single Formula**: Combina ambas dimensiones en una métrica comparable
+4. **Prevents Concentration**: Evitar que todos los tasks vayan a un solo agent
+
+---
+
+## Alternatives Considered
+
+### ❌ Success Rate Only
+- **Pros**: Selecciona best performer
+- **Cons**: Concentra todas las tasks, agent se sobrecarga
+
+### ❌ Round-Robin (Equal Distribution)
+- **Pros**: Simple, fair distribution
+- **Cons**: No considera capability, bad agents get same load
+
+### ✅ Success Rate / (1 + Load) (CHOSEN)
+- Balancea expertise con availability
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Considers both capability and availability
+- ✅ Simple, single metric for comparison
+- ✅ Prevents overloading high-performing agents
+- ✅ Encourages fair distribution
+
+**Cons**:
+- ⚠️ Formula is simplified (linear load penalty)
+- ⚠️ May sacrifice quality for load balance
+- ⚠️ Requires real-time load tracking
+
+---
+
+## Implementation
+
+**Agent Load Tracking**:
+```rust
+// crates/vapora-swarm/src/coordinator.rs
+
+pub struct AgentState {
+    pub id: String,
+    pub role: AgentRole,
+    pub status: AgentStatus,  // Ready, Busy, Offline
+    pub in_flight_tasks: u32,
+    pub max_concurrent: u32,
+    pub success_rate: f32,     // [0.0, 1.0]
+    pub avg_latency_ms: u32,
+}
+
+impl AgentState {
+    /// Current load (0.0 = idle, 1.0 = at capacity)
+    pub fn current_load(&self) -> f32 {
+        (self.in_flight_tasks as f32) / (self.max_concurrent as f32)
+    }
+
+    /// Assignment score: success_rate / (1 + load)
+    /// Higher = better candidate for task
+    pub fn assignment_score(&self) -> f32 {
+        self.success_rate / (1.0 + self.current_load())
+    }
+}
+```
+
+**Task Assignment Logic**:
+```rust
+pub async fn assign_task_to_best_agent(
+    task: &Task,
+    agents: &[AgentState],
+) -> Result<String> {
+    // Filter eligible agents (matching role, online)
+    let eligible: Vec<_> = agents
+        .iter()
+        .filter(|a| {
+            a.status == AgentStatus::Ready || a.status == AgentStatus::Busy
+        })
+        .collect();
+
+    if eligible.is_empty() {
+        return Err(Error::NoAgentsAvailable);
+    }
+
+    // Score each agent
+    let mut scored: Vec<_> = eligible
+        .iter()
+        .map(|agent| {
+            let score = agent.assignment_score();
+            (agent.id.clone(), score)
+        })
+        .collect();
+
+    // Sort by score descending
+    scored.sort_by(|a, b| {
+        b.1.partial_cmp(&a.1).unwrap_or(std::cmp::Ordering::Equal)
+    });
+
+    // Assign to highest scoring agent
+    let selected_agent_id = scored[0].0.clone();
+
+    // Increment in-flight counter
+    if let Some(agent) = agents.iter_mut().find(|a| a.id == selected_agent_id) {
+        agent.in_flight_tasks += 1;
+    }
+
+    Ok(selected_agent_id)
+}
+```
+
+**Load Calculation Examples**:
+```
+Agent A: success_rate = 0.95, in_flight = 2, max_concurrent = 5
+  load = 2/5 = 0.4
+  score = 0.95 / (1 + 0.4) = 0.95 / 1.4 = 0.68
+
+Agent B: success_rate = 0.85, in_flight = 0, max_concurrent = 5
+  load = 0/5 = 0.0
+  score = 0.85 / (1 + 0.0) = 0.85 / 1.0 = 0.85 ← Selected
+
+Agent C: success_rate = 0.90, in_flight = 5, max_concurrent = 5
+  load = 5/5 = 1.0
+  score = 0.90 / (1 + 1.0) = 0.90 / 2.0 = 0.45
+```
+
+**Real-Time Metrics**:
+```rust
+pub async fn collect_swarm_metrics(
+    agents: &[AgentState],
+) -> SwarmMetrics {
+    SwarmMetrics {
+        total_agents: agents.len(),
+        idle_agents: agents.iter().filter(|a| a.in_flight_tasks == 0).count(),
+        busy_agents: agents.iter().filter(|a| a.in_flight_tasks > 0).count(),
+        offline_agents: agents.iter().filter(|a| a.status == AgentStatus::Offline).count(),
+        total_in_flight: agents.iter().map(|a| a.in_flight_tasks).sum::<u32>(),
+        avg_success_rate: agents.iter().map(|a| a.success_rate).sum::<f32>() / agents.len() as f32,
+        avg_load: agents.iter().map(|a| a.current_load()).sum::<f32>() / agents.len() as f32,
+    }
+}
+```
+
+**Prometheus Metrics**:
+```rust
+// Register metrics
+lazy_static::lazy_static! {
+    static ref TASK_ASSIGNMENTS: Counter = Counter::new(
+        "vapora_task_assignments_total",
+        "Total task assignments"
+    ).unwrap();
+
+    static ref AGENT_LOAD: Gauge = Gauge::new(
+        "vapora_agent_current_load",
+        "Current agent load (0-1)"
+    ).unwrap();
+
+    static ref ASSIGNMENT_SCORE: Histogram = Histogram::new(
+        "vapora_assignment_score",
+        "Assignment score distribution"
+    ).unwrap();
+}
+
+// Record metrics
+TASK_ASSIGNMENTS.inc();
+AGENT_LOAD.set(best_agent.current_load());
+ASSIGNMENT_SCORE.observe(best_agent.assignment_score());
+```
+

+
+## Verification
+
+```bash
+# Test assignment score calculation
+cargo test -p vapora-swarm test_assignment_score_calculation
+
+# Test load factor impact
+cargo test -p vapora-swarm test_load_factor_impact
+
+# Test best agent selection
+cargo test -p vapora-swarm test_select_best_agent
+
+# Test fair distribution (no concentration)
+cargo test -p vapora-swarm test_fair_distribution
+
+# Integration: assign multiple tasks sequentially
+cargo test -p vapora-swarm test_assignment_sequence
+
+# Load balancing under stress
+cargo test -p vapora-swarm test_load_balancing_stress
+```
+
+**Expected Output**:
+- Agents with high success_rate + low load selected first
+- Load increases after each assignment
+- Fair distribution across agents
+- No single agent receiving all tasks
+- Metrics tracked accurately
+- Scores properly reflect trade-off
+
+---
+
+## Consequences
+
+### Fairness
+- High-performing agents get more tasks (deserved)
+- Overloaded agents get fewer tasks (protection)
+- Fair distribution emerges automatically
+
+### Performance
+- Task latency depends on agent load (may queue)
+- Peak throughput = sum of all agent max_concurrent
+- SLA contracts respect per-agent limits
+
+### Scaling
+- Adding agents increases total capacity
+- Load automatically redistributes
+- Horizontal scaling works naturally
+
+### Monitoring
+- Track assignment distribution
+- Alert if concentration detected
+- Identify bottleneck agents

+# ADR-019: Temporal Execution History con Daily Windowing
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Knowledge Graph Team
+**Technical Story**: Tracking agent execution history with daily aggregation for learning curves
+
+---
+
+## Decision
+
+Implementar **temporal execution history** con daily windowed aggregations para computar learning curves.
+
+---
+
+## Rationale
+
+1. **Learning Curves**: Daily aggregations permiten ver trends (improving/stable/declining)
+2. **Causal Reasoning**: Histórico permite rastrear problemas a raíz
+3. **Temporal Analysis**: Comparer performance across days/weeks
+4. **Efficient Queries**: Daily windows permiten group-by queries eficientes
+
+---
+
+## Alternatives Considered
+
+### ❌ Per-Execution Only (No Aggregation)
+- **Pros**: Maximum detail
+- **Cons**: Queries slow, hard to identify trends
+
+### ❌ Monthly Aggregation Only
+- **Pros**: Compact
+- **Cons**: Misses weekly trends, loses detail
+
+### ✅ Daily Windows (CHOSEN)
+- Good balance: detail + trend visibility
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Trends visible at daily granularity
+- ✅ Learning curves computable
+- ✅ Efficient aggregation queries
+- ✅ Retention policy compatible
+
+**Cons**:
+- ⚠️ Storage overhead (daily windows)
+- ⚠️ Intra-day trends hidden (needs hourly for detail)
+- ⚠️ Rollup complexity
+
+---
+
+## Implementation
+
+**Execution Record Model**:
+```rust
+// crates/vapora-knowledge-graph/src/models.rs
+
+pub struct ExecutionRecord {
+    pub id: String,

+**Key Files**:
+- `/crates/vapora-knowledge-graph/src/models.rs` (models)
+- `/crates/vapora-knowledge-graph/src/aggregation.rs` (daily aggregation)
+- `/crates/vapora-knowledge-graph/src/learning.rs` (learning curves)
+

+
+## Verification
+
+```bash
+# Test execution recording with daily window
+cargo test -p vapora-knowledge-graph test_execution_recording
+
+# Test daily aggregation
+cargo test -p vapora-knowledge-graph test_daily_aggregation
+
+# Test learning curve computation (7 days)
+cargo test -p vapora-knowledge-graph test_learning_curve_7day
+
+# Test trend detection
+cargo test -p vapora-knowledge-graph test_trend_detection
+
+# Integration: full lifecycle
+cargo test -p vapora-knowledge-graph test_temporal_history_lifecycle
+```
+
+**Expected Output**:
+- Executions recorded with daily_window set
+- Daily aggregations computed correctly
+- Learning curves show trends
+- Trends detected accurately (improving/stable/declining)
+- Queries efficient with daily windows
+
+---
+
+## Consequences
+
+### Data Retention
+- Daily aggregations permanent (minimal storage)
+- Individual execution records archived after 30 days
+- Trend analysis available indefinitely
+
+### Trend Visibility
+- Daily trends visible immediately
+- Week-over-week comparisons possible
+- Month-over-month trends computable
+
+### Performance
+- Aggregation queries use indexes (efficient)
+- Daily rollup automatic (background task)
+- No real-time overhead
+
+### Monitoring
+- Trends inform agent selection decisions
+- Declining agents flagged for investigation
+- Improving agents promoted
+
+---

+# ADR-020: Audit Trail para Compliance
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Security & Compliance Team
+**Technical Story**: Logging all significant workflow events for compliance and incident investigation
+
+---
+
+## Decision
+
+Implementar **comprehensive audit trail** con logging de todos los workflow events, queryable por workflow/actor/tipo.
+
+---
+
+## Rationale
+
+1. **Compliance**: Regulaciones requieren audit trail (HIPAA, SOC2, etc.)
+2. **Incident Investigation**: Reconstruir qué pasó cuando
+3. **Event Sourcing Ready**: Audit trail puede ser base para event sourcing architecture
+4. **User Accountability**: Track quién hizo qué cuándo
+
+---
+
+## Alternatives Considered
+
+### ❌ Logs Only (No Structured Audit)
+- **Pros**: Simple
+- **Cons**: Hard to query, no compliance value
+
+### ❌ Application-Embedded Logging
+- **Pros**: Close to business logic
+- **Cons**: Fragmented, easy to miss events
+
+### ✅ Centralized Audit Trail (CHOSEN)
+- Queryable, compliant, comprehensive
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Queryable by workflow, actor, event type
+- ✅ Compliance-ready
+- ✅ Incident investigation support
+- ✅ Event sourcing ready
+
+**Cons**:
+- ⚠️ Storage overhead (every event logged)
+- ⚠️ Query performance depends on indexing
+- ⚠️ Retention policy tradeoff
+
+---
+
+## Implementation
+
+**Audit Event Model**:
+```rust
+// crates/vapora-backend/src/audit.rs
+
+pub struct AuditEvent {
+    pub id: String,
+    pub timestamp: DateTime<Utc>,
+    pub actor: String,                // User ID or service name
+    pub action: AuditAction,          // Create, Update, Delete, Execute
+    pub resource_type: String,        // Project, Task, Agent, Workflow
+    pub resource_id: String,
+    pub details: serde_json::Value,   // Action-specific details
+    pub outcome: AuditOutcome,        // Success, Failure, PartialSuccess
+    pub error: Option<String>,        // Error message if failed
+}
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub enum AuditAction {
+    Create,
+    Update,
+    Delete,
+    Execute,
+    Assign,
+    Complete,
+    Override,
+    QuerySecret,
+    ViewAudit,
+}
+
+#[derive(Debug, Clone, Copy, PartialEq, Eq)]
+pub enum AuditOutcome {
+    Success,
+    Failure,
+    PartialSuccess,
+}
+```
+
+**Logging Events**:
+```rust
+pub async fn log_event(
+    db: &Surreal<Ws>,
+    actor: &str,
+    action: AuditAction,
+    resource_type: &str,
+    resource_id: &str,
+    details: serde_json::Value,
+    outcome: AuditOutcome,
+) -> Result<String> {
+    let event = AuditEvent {
+        id: uuid::Uuid::new_v4().to_string(),
+        timestamp: Utc::now(),
+        actor: actor.to_string(),
+        action,
+        resource_type: resource_type.to_string(),
+        resource_id: resource_id.to_string(),
+        details,
+        outcome,
+        error: None,
+    };
+
+    let id = db
+        .create("audit_events")
+        .content(&event)
+        .await?
+        .id
+        .unwrap();
+
+    Ok(id)
+}
+
+pub async fn log_event_with_error(
+    db: &Surreal<Ws>,
+    actor: &str,
+    action: AuditAction,
+    resource_type: &str,
+    resource_id: &str,
+    error: String,
+) -> Result<String> {
+    let event = AuditEvent {
+        id: uuid::Uuid::new_v4().to_string(),
+        timestamp: Utc::now(),
+        actor: actor.to_string(),
+        action,
+        resource_type: resource_type.to_string(),
+        resource_id: resource_id.to_string(),
+        details: json!({}),
+        outcome: AuditOutcome::Failure,
+        error: Some(error),
+    };
+
+    let id = db
+        .create("audit_events")
+        .content(&event)
+        .await?
+        .id
+        .unwrap();
+
+    Ok(id)
+}
+```
+
+**Audit Integration in Handlers**:
+```rust
+// In task creation handler
+pub async fn create_task(
+    State(app_state): State<AppState>,
+    Path(project_id): Path<String>,
+    Json(req): Json<CreateTaskRequest>,
+) -> Result<Json<Task>, ApiError> {
+    let user = get_current_user()?;
+
+    // Create task
+    let task = app_state
+        .task_service
+        .create_task(&user.tenant_id, &project_id, &req)
+        .await?;
+
+    // Log audit event
+    app_state.audit_log(
+        &user.id,
+        AuditAction::Create,
+        "task",
+        &task.id,
+        json!({
+            "project_id": &project_id,
+            "title": &task.title,
+            "priority": &task.priority,
+        }),
+        AuditOutcome::Success,
+    ).await.ok();  // Don't fail if audit logging fails
+
+    Ok(Json(task))
+}
+```
+
+**Querying Audit Trail**:
+```rust
+pub async fn query_audit_trail(
+    db: &Surreal<Ws>,
+    filters: AuditQuery,
+) -> Result<Vec<AuditEvent>> {
+    let mut query = String::from(
+        "SELECT * FROM audit_events WHERE 1=1"
+    );
+
+    if let Some(workflow_id) = filters.workflow_id {
+        query.push_str(&format!(" AND resource_id = '{}'", workflow_id));
+    }
+    if let Some(actor) = filters.actor {
+        query.push_str(&format!(" AND actor = '{}'", actor));
+    }
+    if let Some(action) = filters.action {
+        query.push_str(&format!(" AND action = '{:?}'", action));
+    }
+    if let Some(since) = filters.since {
+        query.push_str(&format!(" AND timestamp > '{}'", since));
+    }
+
+    query.push_str(" ORDER BY timestamp DESC LIMIT 1000");
+
+    let events = db.query(&query).await?
+        .take::<Vec<AuditEvent>>(0)?
+        .unwrap_or_default();
+
+    Ok(events)
+}
+```
+
+**Compliance Report**:
+```rust
+pub async fn generate_compliance_report(
+    db: &Surreal<Ws>,
+    start_date: Date,
+    end_date: Date,
+) -> Result<ComplianceReport> {
+    // Query all events in date range
+    let events = db.query(
+        "SELECT COUNT() as event_count, actor, action \
+         FROM audit_events \
+         WHERE timestamp >= $1 AND timestamp < $2 \
+         GROUP BY actor, action"
+    )
+    .bind((start_date, end_date))
+    .await?;
+
+    // Generate report with statistics
+    Ok(ComplianceReport {
+        period: (start_date, end_date),
+        total_events: events.len(),
+        unique_actors: /* count unique */,
+        actions_by_type: /* aggregate */,
+        failures: /* filter failures */,
+    })
+}
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/audit.rs` (audit implementation)
+- `/crates/vapora-backend/src/api/` (audit logging in handlers)
+- `/crates/vapora-backend/src/services/` (audit logging in services)
+

+
+## Verification
+
+```bash
+# Test audit event creation
+cargo test -p vapora-backend test_audit_event_logging
+
+# Test audit trail querying
+cargo test -p vapora-backend test_query_audit_trail
+
+# Test filtering by actor/action/resource
+cargo test -p vapora-backend test_audit_filtering
+
+# Test error logging
+cargo test -p vapora-backend test_audit_error_logging
+
+# Integration: full workflow with audit
+cargo test -p vapora-backend test_audit_full_workflow
+
+# Compliance report generation
+cargo test -p vapora-backend test_compliance_report_generation
+```
+
+**Expected Output**:
+- All significant events logged
+- Queryable by workflow/actor/action
+- Timestamps accurate
+- Errors captured with messages
+- Compliance reports generated correctly
+
+---
+
+## Consequences
+
+### Data Management
+- Audit events retained per compliance policy
+- Separate archive for long-term retention
+- Immutable logs (append-only)
+
+### Performance
+- Audit logging should not block main operation
+- Async logging to avoid latency impact
+- Indexes on (resource_id, timestamp) for queries
+
+### Privacy
+- Sensitive data (passwords, keys) not logged
+- PII handled per data protection regulations
+- Access to audit trail restricted
+
+### Compliance
+- Supports HIPAA, SOC2, GDPR requirements
+- Incident investigation support
+- Regulatory audit trail available

+<strong>Deciders</strong>: Frontend Architecture Team
+<strong>Technical Story</strong>: Enabling real-time workflow progress updates to multiple clients</p>
+<hr />
+<h2 id="decision"><a class="header" href="#decision">Decision</a></h2>
+<p>Implementar <strong>real-time WebSocket updates</strong> usando <code>tokio::sync::broadcast</code> para pub/sub de workflow progress.</p>
+<hr />
+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Real-Time UX</strong>: Usuarios ven cambios inmediatos (no polling)</li>
+<li><strong>Broadcast Efficiency</strong>: <code>broadcast</code> channel permite fan-out a múltiples clientes</li>
+<li><strong>No State Tracking</strong>: No mantener per-client state, channel maneja distribución</li>
+<li><strong>Async-Native</strong>: <code>tokio::sync</code> integrado con Tokio runtime</li>
+</ol>
+<hr />
+<h2 id="alternatives-considered"><a class="header" href="#alternatives-considered">Alternatives Considered</a></h2>
+<h3 id="-http-long-polling"><a class="header" href="#-http-long-polling">❌ HTTP Long-Polling</a></h3>
+<ul>
+<li><strong>Pros</strong>: Simple, no WebSocket complexity</li>

+<h3 id="-server-sent-events-sse"><a class="header" href="#-server-sent-events-sse">❌ Server-Sent Events (SSE)</a></h3>
+<ul>

+<h2 id="trade-offs"><a class="header" href="#trade-offs">Trade-offs</a></h2>
+<p><strong>Pros</strong>:</p>
+<ul>
+<li>✅ Real-time updates (sub-100ms latency)</li>
+<li>✅ Efficient broadcast (no per-client loops)</li>
+<li>✅ Bidirectional communication</li>
+<li>✅ Lower bandwidth than polling</li>
+</ul>
+<p><strong>Cons</strong>:</p>

+# ADR-021: Real-Time WebSocket Updates via Broadcast
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Frontend Architecture Team
+**Technical Story**: Enabling real-time workflow progress updates to multiple clients
+
+---
+
+## Decision
+
+Implementar **real-time WebSocket updates** usando `tokio::sync::broadcast` para pub/sub de workflow progress.
+
+---
+
+## Rationale
+
+1. **Real-Time UX**: Usuarios ven cambios inmediatos (no polling)
+2. **Broadcast Efficiency**: `broadcast` channel permite fan-out a múltiples clientes
+3. **No State Tracking**: No mantener per-client state, channel maneja distribución
+4. **Async-Native**: `tokio::sync` integrado con Tokio runtime
+
+---
+
+## Alternatives Considered
+
+### ❌ HTTP Long-Polling
+- **Pros**: Simple, no WebSocket complexity
+- **Cons**: High latency, resource-intensive
+
+### ❌ Server-Sent Events (SSE)
+- **Pros**: HTTP-based, simpler than WebSocket
+- **Cons**: Unidirectional only (server→client)
+
+### ✅ WebSocket + Broadcast (CHOSEN)
+- Bidirectional, low latency, efficient fan-out
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Real-time updates (sub-100ms latency)
+- ✅ Efficient broadcast (no per-client loops)
+- ✅ Bidirectional communication
+- ✅ Lower bandwidth than polling
+
+**Cons**:
+- ⚠️ Connection state management complex
+- ⚠️ Harder to scale beyond single server
+- ⚠️ Client reconnection handling needed
+
+---
+
+## Implementation
+
+**Broadcast Channel Setup**:
+```rust
+// crates/vapora-backend/src/main.rs
+
+use tokio::sync::broadcast;
+
+// Create broadcast channel (buffer size = 100 messages)
+let (tx, _rx) = broadcast::channel(100);
+
+// Share broadcaster in app state
+let app_state = AppState::new(/* ... */)
+    .with_broadcast_tx(tx.clone());
+```
+
+**Workflow Progress Event**:
+```rust
+// crates/vapora-backend/src/workflow.rs
+
+#[derive(Debug, Clone, Serialize, Deserialize)]
+pub struct WorkflowUpdate {
+    pub workflow_id: String,
+    pub status: WorkflowStatus,
+    pub current_step: u32,
+    pub total_steps: u32,
+    pub message: String,
+    pub timestamp: DateTime<Utc>,
+}
+
+pub async fn update_workflow_status(
+    db: &Surreal<Ws>,
+    tx: &broadcast::Sender<WorkflowUpdate>,
+    workflow_id: &str,
+    status: WorkflowStatus,
+) -> Result<()> {
+    // Update database
+    let updated = db
+        .query("UPDATE workflows SET status = $1 WHERE id = $2")
+        .bind((status, workflow_id))
+        .await?;
+
+    // Broadcast update to all subscribers
+    let update = WorkflowUpdate {
+        workflow_id: workflow_id.to_string(),
+        status,
+        current_step: 0,  // Fetch from DB if needed
+        total_steps: 0,
+        message: format!("Workflow status changed to {:?}", status),
+        timestamp: Utc::now(),
+    };
+
+    // Ignore if no subscribers (channel will be dropped)
+    let _ = tx.send(update);
+
+    Ok(())
+}
+```
+
+**WebSocket Handler**:
+```rust
+// crates/vapora-backend/src/api/websocket.rs
+
+use axum::extract::ws::{WebSocket, WebSocketUpgrade};
+use futures::{sink::SinkExt, stream::StreamExt};
+
+pub async fn websocket_handler(
+    ws: WebSocketUpgrade,
+    State(app_state): State<AppState>,
+    Path(workflow_id): Path<String>,
+) -> impl IntoResponse {
+    ws.on_upgrade(|socket| handle_socket(socket, app_state, workflow_id))
+}
+
+async fn handle_socket(
+    socket: WebSocket,
+    app_state: AppState,
+    workflow_id: String,
+) {
+    let (mut sender, mut receiver) = socket.split();
+
+    // Subscribe to workflow updates
+    let mut rx = app_state.broadcast_tx.subscribe();
+
+    // Task 1: Forward broadcast updates to WebSocket client
+    let workflow_id_clone = workflow_id.clone();
+    let send_task = tokio::spawn(async move {
+        while let Ok(update) = rx.recv().await {
+            // Filter: only send updates for this workflow
+            if update.workflow_id == workflow_id_clone {
+                if let Ok(msg) = serde_json::to_string(&update) {
+                    if sender.send(Message::Text(msg)).await.is_err() {
+                        break;  // Client disconnected
+                    }
+                }
+            }
+        }
+    });
+
+    // Task 2: Listen for client messages (if any)
+    let mut recv_task = tokio::spawn(async move {
+        while let Some(Ok(msg)) = receiver.next().await {
+            match msg {
+                Message::Close(_) => break,
+                Message::Ping(data) => {
+                    // Respond to ping (keep-alive)
+                    let _ = receiver.send(Message::Pong(data)).await;
+                }
+                _ => {}
+            }
+        }
+    });
+
+    // Wait for either task to complete (client disconnect or broadcast end)
+    tokio::select! {
+        _ = &mut send_task => {},
+        _ = &mut recv_task => {},
+    }
+}
+```
+
+**Frontend Integration (Leptos)**:
+```rust
+// crates/vapora-frontend/src/api/websocket.rs
+
+use leptos::*;
+
+#[component]
+pub fn WorkflowProgressMonitor(workflow_id: String) -> impl IntoView {
+    let (progress, set_progress) = create_signal::<Option<WorkflowUpdate>>(None);
+
+    create_effect(move |_| {
+        let workflow_id = workflow_id.clone();
+
+        spawn_local(async move {
+            match create_websocket_connection(&format!(
+                "ws://localhost:8001/api/workflows/{}/updates",
+                workflow_id
+            )) {
+                Ok(ws) => {
+                    loop {
+                        match ws.recv().await {
+                            Ok(msg) => {
+                                if let Ok(update) = serde_json::from_str::<WorkflowUpdate>(&msg) {
+                                    set_progress(Some(update));
+                                }
+                            }
+                            Err(_) => break,
+                        }
+                    }
+                }
+                Err(e) => eprintln!("WebSocket error: {:?}", e),
+            }
+        });
+    });
+
+    view! {
+        <div class="workflow-progress">
+            {move || {
+                progress().map(|update| {
+                    view! {
+                        <div class="progress-item">
+                            <p>{&update.message}</p>
+                            <progress
+                                value={update.current_step}
+                                max={update.total_steps}
+                            />
+                        </div>
+                    }
+                })
+            }}
+        </div>
+    }
+}
+```
+
+**Connection Management**:
+```rust
+pub async fn connection_with_reconnect(
+    ws_url: &str,
+    max_retries: u32,
+) -> Result<WebSocket> {
+    let mut retries = 0;
+
+    loop {
+        match connect_websocket(ws_url).await {
+            Ok(ws) => return Ok(ws),
+            Err(e) if retries < max_retries => {
+                retries += 1;
+                let backoff_ms = 100 * 2_u64.pow(retries);
+                tokio::time::sleep(Duration::from_millis(backoff_ms)).await;
+            }
+            Err(e) => return Err(e),
+        }
+    }
+}
+```

+**Key Files**:
+- `/crates/vapora-backend/src/api/websocket.rs` (WebSocket handler)
+- `/crates/vapora-backend/src/workflow.rs` (broadcast events)
+- `/crates/vapora-frontend/src/api/websocket.rs` (Leptos client)
+

+
+## Verification
+
+```bash
+# Test broadcast channel basic functionality
+cargo test -p vapora-backend test_broadcast_basic
+
+# Test multiple subscribers
+cargo test -p vapora-backend test_broadcast_multiple_subscribers
+
+# Test filtering (only send relevant updates)
+cargo test -p vapora-backend test_broadcast_filtering
+
+# Integration: full WebSocket lifecycle
+cargo test -p vapora-backend test_websocket_full_lifecycle
+
+# Connection stability test
+cargo test -p vapora-backend test_websocket_disconnection_handling
+
+# Load test: multiple concurrent connections
+cargo test -p vapora-backend test_websocket_concurrent_connections
+```
+
+**Expected Output**:
+- Updates broadcast to all subscribers
+- Only relevant workflow updates sent per subscription
+- Client disconnections handled gracefully
+- Reconnection with backoff works
+- Latency < 100ms
+- Scales to 100+ concurrent connections
+
+---
+
+## Consequences
+
+### Scalability
+- Single server: broadcast works well
+- Multiple servers: need message broker (Redis, NATS)
+- Load balancer: sticky sessions or server-wide broadcast
+
+### Connection Management
+- Automatic cleanup on client disconnect
+- Backpressure handling (dropped messages if queue full)
+- Per-connection state minimal
+
+### Frontend
+- Real-time UX without polling
+- Automatic disconnection handling
+- Graceful degradation if WebSocket unavailable
+
+### Monitoring
+- Track concurrent WebSocket connections
+- Monitor broadcast channel depth
+- Alert on high message loss

+# ADR-022: Two-Tier Error Handling (thiserror + HTTP Wrapper)
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Backend Architecture Team
+**Technical Story**: Separating domain errors from HTTP response concerns
+
+---
+
+## Decision
+
+Implementar **two-tier error handling**: `thiserror` para domain errors, `ApiError` wrapper para HTTP responses.
+
+---
+
+## Rationale
+
+1. **Separation of Concerns**: Domain logic no conoce HTTP (reusable en CLI, libraries)
+2. **Reusability**: Mismo error type usado por backend, frontend (via API), agents
+3. **Type Safety**: Compiler ensures all error cases handled
+4. **HTTP Mapping**: Clean mapping from domain errors to HTTP status codes
+
+---
+
+## Alternatives Considered
+
+### ❌ Single Error Type (Mixed Domain + HTTP)
+- **Pros**: Simple
+- **Cons**: Domain logic coupled to HTTP, not reusable
+
+### ❌ Error Strings Only
+- **Pros**: Simple, flexible
+- **Cons**: No type safety, easy to forget cases
+
+### ✅ Two-Tier (Domain + HTTP wrapper) (CHOSEN)
+- Clean separation, reusable, type-safe
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Domain logic independent of HTTP
+- ✅ Error types reusable in different contexts
+- ✅ Type-safe error handling
+- ✅ Explicit HTTP status code mapping
+
+**Cons**:
+- ⚠️ Two error types to maintain
+- ⚠️ Conversion logic between layers
+- ⚠️ Slightly more verbose
+
+---
+
+## Implementation
+
+**Domain Error Type**:
+```rust
+// crates/vapora-shared/src/error.rs
+
+use thiserror::Error;
+
+#[derive(Error, Debug)]
+pub enum VaporaError {
+    #[error("Project not found: {0}")]
+    ProjectNotFound(String),
+
+    #[error("Task not found: {0}")]
+    TaskNotFound(String),
+
+    #[error("Unauthorized access to resource: {0}")]
+    Unauthorized(String),
+
+    #[error("Agent {agent_id} failed with: {reason}")]
+    AgentExecutionFailed { agent_id: String, reason: String },
+
+    #[error("Budget exceeded for role {role}: spent ${spent}, limit ${limit}")]
+    BudgetExceeded { role: String, spent: u32, limit: u32 },
+
+    #[error("Database error: {0}")]
+    DatabaseError(#[from] surrealdb::Error),
+
+    #[error("External service error: {service}: {message}")]
+    ExternalServiceError { service: String, message: String },
+
+    #[error("Invalid request: {0}")]
+    ValidationError(String),
+
+    #[error("Internal server error: {0}")]
+    Internal(String),

+        .map_err(ApiError::from)?;  // Convert to HTTP error
+
+    Ok(Json(project))
+}
+```
+
+**Usage in Services**:
+```rust

+
+pub async fn get_project(

+**Key Files**:
+- `/crates/vapora-shared/src/error.rs` (domain errors)
+- `/crates/vapora-backend/src/api/error.rs` (HTTP wrapper)
+- `/crates/vapora-backend/src/api/` (handlers using errors)
+- `/crates/vapora-backend/src/services/` (services using errors)

+
+## Verification
+
+```bash
+# Test error creation and conversion
+cargo test -p vapora-backend test_error_conversion
+
+# Test HTTP status code mapping
+cargo test -p vapora-backend test_error_status_codes
+
+# Test error propagation with ?
+cargo test -p vapora-backend test_error_propagation
+
+# Test API responses with errors
+cargo test -p vapora-backend test_api_error_response
+
+# Integration: full error flow
+cargo test -p vapora-backend test_error_full_flow
+```
+
+**Expected Output**:
+- Domain errors created correctly
+- Status codes mapped appropriately
+- Error messages clear and helpful
+- HTTP responses valid JSON
+- Error propagation with ? works
+
+---
+
+## Consequences
+
+### Error Handling Pattern
+- Use `?` operator for propagation
+- Convert at HTTP boundary only
+- Domain logic error-agnostic
+
+### Maintainability
+- Errors centralized in shared crate
+- HTTP mapping documented in one place
+- Easy to add new error types
+
+### Reusability
+- Same error type in CLI tools
+- Agents can use domain errors
+- Frontend consumes HTTP errors
+

+# ADR-023: Multi-Layer Testing Strategy
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Quality Assurance Team
+**Technical Story**: Building confidence through unit, integration, and real-database tests
+
+---
+
+## Decision
+
+Implementar **multi-layer testing**: unit tests (inline), integration tests (tests/ dir), real DB connections.
+
+---
+
+## Rationale
+
+1. **Unit Tests**: Fast feedback on logic changes
+2. **Integration Tests**: Verify components work together
+3. **Real DB Tests**: Catch database schema/query issues
+4. **218+ Tests**: Comprehensive coverage across 13 crates
+
+---
+
+## Alternatives Considered
+
+### ❌ Unit Tests Only
+- **Pros**: Fast
+- **Cons**: Miss integration bugs, schema issues
+
+### ❌ Integration Tests Only
+- **Pros**: Comprehensive
+- **Cons**: Slow, harder to debug
+
+### ✅ Multi-Layer (CHOSEN)
+- All three layers catch different issues
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Fast feedback (unit)
+- ✅ Integration validation (integration)
+- ✅ Real-world confidence (real DB)
+- ✅ 218+ tests total coverage
+
+**Cons**:
+- ⚠️ Slow full test suite (~5 minutes)
+- ⚠️ DB tests require test environment
+- ⚠️ More test code to maintain
+
+---
+
+## Implementation
+
+**Unit Tests (Inline)**:
+```rust
+// crates/vapora-agents/src/learning_profile.rs
+
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_expertise_score_empty() {
+        let profile = TaskTypeLearning {
+            agent_id: "test".to_string(),
+            task_type: "architecture".to_string(),
+            executions_total: 0,
+            records: vec![],
+            ..Default::default()
+        };
+
+        assert_eq!(profile.expertise_score(), 0.0);
+    }
+
+    #[test]
+    fn test_confidence_weighting() {
+        let profile = TaskTypeLearning {
+            executions_total: 20,
+            ..Default::default()
+        };
+        assert_eq!(profile.confidence(), 1.0);
+
+        let profile_partial = TaskTypeLearning {
+            executions_total: 10,
+            ..Default::default()
+        };
+        assert_eq!(profile_partial.confidence(), 0.5);
+    }
+}
+```
+
+**Integration Tests**:
+```rust
+// crates/vapora-backend/tests/integration_tests.rs
+
+#[tokio::test]
+async fn test_create_project_full_flow() {
+    // Setup: create test database
+    let db = setup_test_db().await;
+    let app_state = create_test_app_state(db.clone()).await;
+
+    // Execute: create project via HTTP
+    let response = app_state
+        .handle_request(
+            "POST",
+            "/api/projects",
+            json!({
+                "title": "Test Project",
+                "description": "A test",
+            }),
+        )
+        .await;
+
+    // Verify: response is 201 Created
+    assert_eq!(response.status(), 201);
+
+    // Verify: project in database
+    let project = db
+        .query("SELECT * FROM projects LIMIT 1")
+        .await
+        .unwrap()
+        .take::<Project>(0)
+        .unwrap()
+        .unwrap();
+
+    assert_eq!(project.title, "Test Project");
+}
+```
+
+**Real Database Tests**:
+```rust
+// crates/vapora-backend/tests/database_tests.rs
+
+#[tokio::test]
+async fn test_multi_tenant_isolation() {
+    let db = setup_real_surrealdb().await;
+
+    // Create projects for two tenants
+    let project_1 = db
+        .create("projects")
+        .content(Project {
+            tenant_id: "tenant:1".to_string(),
+            title: "Project 1".to_string(),
+            ..Default::default()
+        })
+        .await
+        .unwrap();
+
+    let project_2 = db
+        .create("projects")
+        .content(Project {
+            tenant_id: "tenant:2".to_string(),
+            title: "Project 2".to_string(),
+            ..Default::default()
+        })
+        .await
+        .unwrap();
+
+    // Query: tenant 1 should only see their project
+    let results = db
+        .query("SELECT * FROM projects WHERE tenant_id = 'tenant:1'")
+        .await
+        .unwrap()
+        .take::<Vec<Project>>(0)
+        .unwrap();
+
+    assert_eq!(results.len(), 1);
+    assert_eq!(results[0].title, "Project 1");
+}
+```
+
+**Test Utilities**:
+```rust
+// crates/vapora-backend/tests/common/mod.rs
+
+pub async fn setup_test_db() -> Surreal<Mem> {
+    let db = Surreal::new::<surrealdb::engine::local::Mem>()
+        .await
+        .unwrap();
+
+    db.use_ns("vapora").use_db("test").await.unwrap();
+
+    // Initialize schema
+    init_schema(&db).await.unwrap();
+
+    db
+}
+
+pub async fn setup_real_surrealdb() -> Surreal<Ws> {
+    // Connect to test SurrealDB instance
+    let db = Surreal::new::<Ws>("ws://localhost:8000")
+        .await
+        .unwrap();
+
+    db.signin(/* test credentials */).await.unwrap();
+    db.use_ns("test").use_db("test").await.unwrap();
+
+    db
+}
+```
+
+**Running Tests**:
+```bash
+# Run all tests
+cargo test --workspace
+
+# Run unit tests only (fast)
+cargo test --workspace --lib
+
+# Run integration tests
+cargo test --workspace --test "*"
+
+# Run with output
+cargo test --workspace -- --nocapture
+
+# Run specific test
+cargo test -p vapora-backend test_multi_tenant_isolation
+
+# Coverage report
+cargo tarpaulin --workspace --out Html
+```
+
+**Key Files**:
+- `crates/*/src/` (unit tests inline)
+- `crates/*/tests/` (integration tests)
+- `crates/*/tests/common/` (test utilities)
+
+---
+
+## Verification
+
+```bash
+# Count tests across workspace
+cargo test --workspace -- --list | grep "test " | wc -l
+
+# Run all tests with statistics
+cargo test --workspace 2>&1 | grep -E "^test |passed|failed"
+
+# Coverage report
+cargo tarpaulin --workspace --out Html
+# Output: coverage/index.html
+```
+
+**Expected Output**:
+- 218+ tests total
+- All tests passing
+- Coverage > 70%
+- Unit tests < 5 seconds
+- Integration tests < 60 seconds
+
+---
+
+## Consequences
+
+### Testing Cadence
+- Pre-commit: run unit tests
+- PR: run all tests
+- CI/CD: run all tests + coverage
+
+### Test Environment
+- Unit tests: in-memory databases
+- Integration: SurrealDB in-memory
+- Real DB: Docker container (CI/CD only)
+
+### Debugging
+- Unit test failure: easy to debug (isolated)
+- Integration failure: check component interaction
+- DB failure: verify schema and queries
+
+---

+# ADR-024: Service-Oriented Module Architecture
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Backend Architecture Team
+**Technical Story**: Separating HTTP concerns from business logic via service layer
+
+---
+
+## Decision
+
+Implementar **service-oriented architecture**: API layer (thin) delega a service layer (thick).
+
+---
+
+## Rationale
+
+1. **Separation of Concerns**: HTTP != business logic
+2. **Testability**: Services testable without HTTP layer
+3. **Reusability**: Same services usable from CLI, agents, other services
+4. **Maintainability**: Clear responsibility boundaries
+
+---
+
+## Alternatives Considered
+
+### ❌ Handlers Directly Query Database
+- **Pros**: Simple, fewer files
+- **Cons**: Business logic in HTTP layer, not reusable, hard to test
+
+### ❌ Anemic Service Layer (Just CRUD)
+- **Pros**: Simple
+- **Cons**: Business logic still in handlers
+
+### ✅ Service-Oriented with Thick Services (CHOSEN)
+- Services encapsulate business logic
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Clear separation HTTP ≠ business logic
+- ✅ Services independently testable
+- ✅ Reusable across contexts
+- ✅ Easy to add new endpoints
+
+**Cons**:
+- ⚠️ More files (API + Service)
+- ⚠️ Slight latency from extra layer
+- ⚠️ Coordination between layers
+
+---
+
+## Implementation
+
+**API Layer (Thin)**:
+```rust
+// crates/vapora-backend/src/api/projects.rs
+
+pub async fn create_project(
+    State(app_state): State<AppState>,
+    Json(req): Json<CreateProjectRequest>,
+) -> Result<(StatusCode, Json<Project>), ApiError> {
+    // 1. Extract user context
+    let user = get_current_user()?;
+
+    // 2. Delegate to service
+    let project = app_state
+        .project_service
+        .create_project(
+            &user.tenant_id,
+            &req.title,
+            &req.description,
+        )
+        .await
+        .map_err(ApiError::from)?;
+
+    // 3. Return HTTP response
+    Ok((StatusCode::CREATED, Json(project)))
+}
+
+pub async fn get_project(
+    State(app_state): State<AppState>,
+    Path(project_id): Path<String>,
+) -> Result<Json<Project>, ApiError> {
+    let user = get_current_user()?;
+
+    // Delegate to service
+    let project = app_state
+        .project_service
+        .get_project(&user.tenant_id, &project_id)
+        .await
+        .map_err(ApiError::from)?;
+
+    Ok(Json(project))
+}
+```
+
+**Service Layer (Thick)**:
+```rust
+// crates/vapora-backend/src/services/project_service.rs
+
+pub struct ProjectService {
+    db: Surreal<Ws>,
+}
+
+impl ProjectService {
+    pub fn new(db: Surreal<Ws>) -> Self {
+        Self { db }
+    }
+
+    /// Create new project with validation and defaults
+    pub async fn create_project(
+        &self,
+        tenant_id: &str,
+        title: &str,
+        description: &Option<String>,
+    ) -> Result<Project> {
+        // 1. Validate input
+        if title.is_empty() {
+            return Err(VaporaError::ValidationError("Title cannot be empty".into()));
+        }
+        if title.len() > 255 {
+            return Err(VaporaError::ValidationError("Title too long".into()));
+        }
+
+        // 2. Create project
+        let project = Project {
+            id: uuid::Uuid::new_v4().to_string(),
+            tenant_id: tenant_id.to_string(),
+            title: title.to_string(),
+            description: description.clone(),
+            status: ProjectStatus::Active,
+            created_at: Utc::now(),
+            updated_at: Utc::now(),
+            ..Default::default()
+        };
+
+        // 3. Persist to database
+        self.db
+            .create("projects")
+            .content(&project)
+            .await?;
+
+        // 4. Audit log
+        audit_log::log_project_created(tenant_id, &project.id, title)?;
+
+        Ok(project)
+    }
+
+    /// Get project with permission check
+    pub async fn get_project(
+        &self,
+        tenant_id: &str,
+        project_id: &str,
+    ) -> Result<Project> {
+        // 1. Query database
+        let project = self.db
+            .query("SELECT * FROM projects WHERE id = $1 AND tenant_id = $2")
+            .bind((project_id, tenant_id))
+            .await?
+            .take::<Option<Project>>(0)?
+            .ok_or_else(|| VaporaError::ProjectNotFound(project_id.to_string()))?;
+
+        // 2. Permission check (implicit via tenant_id query)
+        Ok(project)
+    }
+
+    /// List projects for tenant with pagination
+    pub async fn list_projects(
+        &self,
+        tenant_id: &str,
+        limit: u32,
+        offset: u32,
+    ) -> Result<(Vec<Project>, u32)> {
+        // 1. Get total count
+        let total = self.db
+            .query("SELECT count(id) FROM projects WHERE tenant_id = $1")
+            .bind(tenant_id)
+            .await?
+            .take::<Option<u32>>(0)?
+            .unwrap_or(0);
+
+        // 2. Get paginated results
+        let projects = self.db
+            .query(
+                "SELECT * FROM projects \
+                 WHERE tenant_id = $1 \
+                 ORDER BY created_at DESC \
+                 LIMIT $2 START $3"
+            )
+            .bind((tenant_id, limit, offset))
+            .await?
+            .take::<Vec<Project>>(0)?
+            .unwrap_or_default();
+
+        Ok((projects, total))
+    }
+}
+```
+
+**AppState (Depends On Services)**:
+```rust
+// crates/vapora-backend/src/api/state.rs
+
+pub struct AppState {
+    pub project_service: ProjectService,
+    pub task_service: TaskService,
+    pub agent_service: AgentService,
+    // Other services...
+}
+
+impl AppState {
+    pub fn new(
+        project_service: ProjectService,
+        task_service: TaskService,
+        agent_service: AgentService,
+    ) -> Self {
+        Self {
+            project_service,
+            task_service,
+            agent_service,
+        }
+    }
+}
+```
+
+**Testable Services**:
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[tokio::test]
+    async fn test_create_project() {
+        let db = setup_test_db().await;
+        let service = ProjectService::new(db);
+
+        let result = service
+            .create_project("tenant:1", "My Project", &None)
+            .await;
+
+        assert!(result.is_ok());
+        let project = result.unwrap();
+        assert_eq!(project.title, "My Project");
+    }
+
+    #[tokio::test]
+    async fn test_create_project_empty_title() {
+        let db = setup_test_db().await;
+        let service = ProjectService::new(db);
+
+        let result = service
+            .create_project("tenant:1", "", &None)
+            .await;
+
+        assert!(result.is_err());
+    }
+}
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/api/` (thin API handlers)
+- `/crates/vapora-backend/src/services/` (thick service logic)
+- `/crates/vapora-backend/src/api/state.rs` (AppState)
+
+---
+
+## Verification
+
+```bash
+# Test service logic independently
+cargo test -p vapora-backend test_service_logic
+
+# Test API handlers
+cargo test -p vapora-backend test_api_handlers
+
+# Verify separation (API shouldn't directly query DB)
+grep -r "\.query(" crates/vapora-backend/src/api/ 2>/dev/null | grep -v service
+
+# Check service reusability (used in multiple places)
+grep -r "ProjectService::" crates/vapora-backend/src/
+```
+
+**Expected Output**:
+- API layer contains only HTTP logic
+- Services contain business logic
+- Services independently testable
+- No direct DB queries in API layer
+
+---
+
+## Consequences
+
+### Code Organization
+- `/api/` for HTTP concerns
+- `/services/` for business logic
+- Clear separation of responsibilities
+
+### Testing
+- API tests mock services
+- Service tests use real database
+- Fast unit tests + integration tests
+
+### Maintainability
+- Business logic changes in one place
+- Adding endpoints: just add API handler
+- Reusing logic: call service from multiple places
+
+### Extensibility
+- CLI tool can use same services
+- Agents can use same services
+- No duplication of business logic
+
+---

+# ADR-025: SurrealDB Scope-Based Multi-Tenancy
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Security & Architecture Team
+**Technical Story**: Implementing defense-in-depth tenant isolation with database scopes
+
+---
+
+## Decision
+
+Implementar **multi-tenancy via SurrealDB scopes + tenant_id fields** para defense-in-depth isolation.
+
+---
+
+## Rationale
+
+1. **Defense-in-Depth**: Tenants isolated en dos niveles (scopes + queries)
+2. **Database-Level**: SurrealDB scopes enforced en DB (no app bugs can leak)
+3. **Application-Level**: Services validate tenant_id (redundant safety)
+4. **Performance**: Scope filtering efficient (pushes down to DB)
+
+---
+
+## Alternatives Considered
+
+### ❌ Application-Level Only
+- **Pros**: Works with any database
+- **Cons**: Bugs in app code can leak data
+
+### ❌ Database-Level Only (Hard Partitioning)
+- **Pros**: Very secure
+- **Cons**: Hard to query across tenants (analytics), complex schema
+
+### ✅ Dual-Level (Scopes + Validation) (CHOSEN)
+- Both layers + application simplicity
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Tenant data isolated at DB level (SurrealDB scopes)
+- ✅ Application-level checks prevent mistakes
+- ✅ Flexible querying (within tenant)
+- ✅ Analytics possible (aggregate across tenants)
+
+**Cons**:
+- ⚠️ Requires discipline (always filter by tenant_id)
+- ⚠️ Complexity in schema (every model has tenant_id)
+- ⚠️ SurrealDB scope syntax to learn
+
+---
+
+## Implementation
+
+**Model Definition with tenant_id**:
+```rust
+// crates/vapora-shared/src/models.rs
+
+pub struct Project {
+    pub id: String,
+    pub tenant_id: String,  // ← Mandatory field
+    pub title: String,
+    pub description: Option<String>,
+    pub created_at: DateTime<Utc>,
+    pub updated_at: DateTime<Utc>,
+}
+
+pub struct Task {
+    pub id: String,
+    pub tenant_id: String,  // ← Mandatory field
+    pub project_id: String,
+    pub title: String,
+    pub status: TaskStatus,
+    pub created_at: DateTime<Utc>,
+}
+```
+
+**SurrealDB Scope Definition**:
+```sql
+-- Create scope for tenant isolation
+DEFINE SCOPE tenant_scope
+    SESSION 24h
+    SIGNUP (
+        CREATE user SET
+            email = $email,

+        tenant_id: tenant_id.to_string(),

+}
+```
+
+**API Handler with Tenant Validation**:
+```rust
+pub async fn get_project(
+    State(app_state): State<AppState>,
+    Path(project_id): Path<String>,
+    request: Request,
+) -> Result<Json<Project>, ApiError> {
+    // 1. Extract tenant from JWT
+    let tenant = extract_tenant_context(&request)?;
+
+    // 2. Call service (tenant passed explicitly)
+    let project = app_state
+        .project_service
+        .get_project(&tenant.tenant_id, &project_id)
+        .await
+        .map_err(ApiError::from)?;
+
+    Ok(Json(project))
+}
+```
+
+**Key Files**:
+- `/crates/vapora-shared/src/models.rs` (models with tenant_id)
+- `/crates/vapora-backend/src/services/` (tenant validation in queries)
+- `/crates/vapora-backend/src/auth/` (tenant context extraction)
+
+---
+
+## Verification
+
+```bash
+# Test tenant isolation (can't access other tenant's data)
+cargo test -p vapora-backend test_tenant_isolation
+
+# Test service enforces tenant_id
+cargo test -p vapora-backend test_service_tenant_check
+
+# Integration: create projects in two tenants, verify isolation
+cargo test -p vapora-backend test_multi_tenant_integration
+
+# Verify database permissions enforced
+# (Run manual query as one tenant, try to access another tenant's data)
+surreal sql --conn ws://localhost:8000
+> USE ns vapora db main;
+> CREATE project SET tenant_id = 'other:tenant', title = 'Hacked';  // Should fail
+```
+
+**Expected Output**:
+- Tenant cannot access other tenant's projects
+- Database permissions block cross-tenant access
+- Service validation catches tenant mismatches
+- Only authenticated user's tenant_id usable
+
+---
+
+## Consequences
+
+### Schema Design
+- Every model must have tenant_id field
+- Queries always include tenant_id filter
+- Indexes on (tenant_id, id) for performance
+
+### Query Patterns
+- Services always filter by tenant_id
+- No queries without WHERE tenant_id = $1
+- Lint/review to enforce
+
+### Data Isolation
+- Tenant data completely isolated
+- No risk of accidental leakage
+- Safe for multi-tenant SaaS
+
+### Scaling
+- Can shard by tenant_id if needed
+- Analytics queries group by tenant
+- Compliance: data export per tenant simple

+# ADR-026: Arc-Based Shared State Management
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Backend Architecture Team
+**Technical Story**: Managing thread-safe shared state across async Tokio handlers
+
+---
+
+## Decision
+
+Implementar **Arc-wrapped shared state** con `RwLock` (read-heavy) y `Mutex` (write-heavy) para coordinación inter-handler.
+
+---
+
+## Rationale
+
+1. **Cheap Clones**: `Arc` enables sharing without duplication
+2. **Thread-Safe**: `RwLock`/`Mutex` provide safe concurrent access
+3. **Async-Native**: Works with Tokio async/await
+4. **Handler Distribution**: Each handler gets Arc clone (scales across threads)
+
+---
+
+## Alternatives Considered
+
+### ❌ Direct Shared References
+- **Pros**: Simple
+- **Cons**: Borrow checker issues in async, unsafe
+
+### ❌ Message Passing Only (Channels)
+- **Pros**: Avoids shared state
+- **Cons**: Overkill for read-heavy state, latency
+
+### ✅ Arc<RwLock<>> / Arc<Mutex<>> (CHOSEN)
+- Right balance of simplicity and safety
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Cheap clones via Arc
+- ✅ Type-safe via Rust borrow checker
+- ✅ Works seamlessly with async/await
+- ✅ RwLock for read-heavy workloads (multiple readers)
+- ✅ Mutex for write-heavy/simple cases
+
+**Cons**:
+- ⚠️ Lock contention possible under high concurrency
+- ⚠️ Deadlock risk if not careful (nested locks)
+- ⚠️ Poisoned lock handling needed
+
+---
+
+## Implementation
+
+**Shared State Definition**:
+```rust
+// crates/vapora-backend/src/api/state.rs
+
+pub struct AppState {
+    pub project_service: Arc<ProjectService>,
+    pub task_service: Arc<TaskService>,
+    pub agent_service: Arc<AgentService>,
+
+    // Shared mutable state
+    pub task_queue: Arc<Mutex<Vec<Task>>>,
+    pub agent_registry: Arc<RwLock<HashMap<String, AgentState>>>,
+    pub metrics: Arc<RwLock<Metrics>>,
+}
+
+impl AppState {
+    pub fn new(
+        project_service: ProjectService,
+        task_service: TaskService,
+        agent_service: AgentService,
+    ) -> Self {
+        Self {
+            project_service: Arc::new(project_service),
+            task_service: Arc::new(task_service),
+            agent_service: Arc::new(agent_service),
+            task_queue: Arc::new(Mutex::new(Vec::new())),
+            agent_registry: Arc::new(RwLock::new(HashMap::new())),
+            metrics: Arc::new(RwLock::new(Metrics::default())),
+        }
+    }
+}
+```
+
+**Using Arc in Handlers**:
+```rust
+// Handlers receive State which is Arc already
+pub async fn create_task(
+    State(app_state): State<AppState>,  // AppState is Arc<AppState>
+    Json(req): Json<CreateTaskRequest>,
+) -> Result<Json<Task>, ApiError> {
+    let task = app_state
+        .task_service
+        .create_task(&req)
+        .await?;
+
+    // Push to shared queue
+    let mut queue = app_state.task_queue.lock().await;
+    queue.push(task.clone());
+
+    Ok(Json(task))
+}
+```
+
+**RwLock Pattern (Read-Heavy)**:
+```rust
+// crates/vapora-backend/src/swarm/registry.rs
+
+pub async fn get_agent_status(
+    app_state: &AppState,
+    agent_id: &str,
+) -> Result<AgentStatus> {
+    // Multiple concurrent readers can hold read lock
+    let registry = app_state.agent_registry.read().await;
+
+    let agent = registry
+        .get(agent_id)
+        .ok_or(VaporaError::NotFound)?;
+
+    Ok(agent.status)
+}
+
+pub async fn update_agent_status(
+    app_state: &AppState,
+    agent_id: &str,
+    new_status: AgentStatus,
+) -> Result<()> {
+    // Exclusive write lock
+    let mut registry = app_state.agent_registry.write().await;
+
+    if let Some(agent) = registry.get_mut(agent_id) {
+        agent.status = new_status;
+        Ok(())
+    } else {
+        Err(VaporaError::NotFound)
+    }
+}
+```
+
+**Mutex Pattern (Write-Heavy)**:
+```rust
+// crates/vapora-backend/src/api/task_queue.rs
+
+pub async fn dequeue_task(
+    app_state: &AppState,
+) -> Option<Task> {
+    let mut queue = app_state.task_queue.lock().await;
+    queue.pop()
+}
+
+pub async fn enqueue_task(
+    app_state: &AppState,
+    task: Task,
+) {
+    let mut queue = app_state.task_queue.lock().await;
+    queue.push(task);
+}
+```
+
+**Avoiding Deadlocks**:
+```rust
+// ✅ GOOD: Single lock acquisition
+pub async fn safe_operation(app_state: &AppState) {
+    let mut registry = app_state.agent_registry.write().await;
+    // Do work
+    // Lock automatically released when dropped
+}
+
+// ❌ BAD: Nested locks (can deadlock)
+pub async fn unsafe_operation(app_state: &AppState) {
+    let mut registry = app_state.agent_registry.write().await;
+    let mut queue = app_state.task_queue.lock().await;  // Risk: lock order inversion
+    // If another task acquires locks in opposite order, deadlock!
+}
+
+// ✅ GOOD: Consistent lock order prevents deadlocks
+// Always acquire: agent_registry → task_queue
+pub async fn safe_nested(app_state: &AppState) {
+    let mut registry = app_state.agent_registry.write().await;
+    let mut queue = app_state.task_queue.lock().await;  // Same order everywhere
+    // Safe from deadlock
+}
+```
+
+**Poisoned Lock Handling**:
+```rust
+pub async fn handle_poisoned_lock(
+    app_state: &AppState,
+) -> Result<Vec<Task>> {
+    match app_state.task_queue.lock().await {
+        Ok(queue) => Ok(queue.clone()),
+        Err(poisoned) => {
+            // Lock was poisoned (panic inside lock)
+            // Recover by using inner value
+            let queue = poisoned.into_inner();
+            Ok(queue.clone())
+        }
+    }
+}
+```
+
+**Key Files**:
+- `/crates/vapora-backend/src/api/state.rs` (state definition)
+- `/crates/vapora-backend/src/main.rs` (state creation)
+- `/crates/vapora-backend/src/api/` (handlers using Arc)
+

+
+## Verification
+
+```bash
+# Test concurrent access to shared state
+cargo test -p vapora-backend test_concurrent_state_access
+
+# Test RwLock read-heavy performance
+cargo test -p vapora-backend test_rwlock_concurrent_reads
+
+# Test Mutex write-heavy correctness
+cargo test -p vapora-backend test_mutex_exclusive_writes
+
+# Integration: multiple handlers accessing shared state
+cargo test -p vapora-backend test_shared_state_integration
+
+# Stress test: high concurrency
+cargo test -p vapora-backend test_shared_state_stress
+```
+
+**Expected Output**:
+- Concurrent reads successful (RwLock)
+- Exclusive writes correct (Mutex)
+- No data races (Rust guarantees)
+- Deadlock-free (consistent lock ordering)
+- High throughput under load
+
+---
+
+## Consequences
+
+### Performance
+- Read locks: low contention (multiple readers)
+- Write locks: exclusive (single writer)
+- Mutex: simple but may serialize
+
+### Concurrency Model
+- Handlers clone Arc (cheap, ~8 bytes)
+- Multiple threads access same data
+- Lock guards released when dropped
+
+### Debugging
+- Data races impossible (Rust compiler)
+- Deadlocks prevented by discipline
+- Poisoned locks rare (panic handling)
+
+### Scaling
+- Per-core scalability excellent (read-heavy)
+- Write contention bottleneck (if heavy)
+- Sharding option for write-heavy

+<h2 id="rationale"><a class="header" href="#rationale">Rationale</a></h2>
+<ol>
+<li><strong>Session Work ≠ Permanent Docs</strong>: Claude Code sessions are temporary, not product docs</li>
+<li><strong>Clear Boundaries</strong>: Different audiences (devs, users, operations)</li>
+<li><strong>Git Structure</strong>: Natural organization via directories</li>

+
+**Date**: January 10, 2026
+**Status**: ✅ COMPLETE
+**Task**: Refactor agent coordinator to reduce latency
+
+---
+
+## What Was Done
+
+1. Analyzed current coordinator performance
+2. Identified bottleneck: sequential task assignment
+3. Implemented parallel task dispatch
+4. Benchmarked: 50ms → 15ms latency
+
+---
+
+## Key Decisions
+
+- Use `tokio::spawn` for parallel dispatch
+- Keep single source of truth (still in Arc&lt;RwLock&gt;)
+
+## Next Steps
+
+(User's choice)

+# ADR-027: Three-Layer Documentation System
+
+**Status**: Accepted | Implemented
+**Date**: 2024-11-01
+**Deciders**: Documentation & Architecture Team
+**Technical Story**: Separating session work from permanent documentation to avoid confusion
+
+---
+
+## Decision
+
+Implementar **three-layer documentation system**: `.coder/` (session), `.claude/` (operational), `docs/` (product).
+
+---
+
+## Rationale
+
+1. **Session Work ≠ Permanent Docs**: Claude Code sessions are temporary, not product docs
+2. **Clear Boundaries**: Different audiences (devs, users, operations)
+3. **Git Structure**: Natural organization via directories
+4. **Maintainability**: Easy to distinguish what's authoritative
+
+---
+
+## Alternatives Considered
+
+### ❌ Single Documentation Folder
+- **Pros**: Simple
+- **Cons**: Session files mixed with product docs, confusion
+
+### ❌ Documentation Only (No Session Tracking)
+- **Pros**: Clean product docs
+- **Cons**: No record of how decisions were made
+
+### ✅ Three Layers (CHOSEN)
+- Separates concerns, clear boundaries
+
+---
+
+## Trade-offs
+
+**Pros**:
+- ✅ Clear separation of concerns
+- ✅ Session files don't pollute product docs
+- ✅ Different retention/publication policies
+- ✅ Audit trail of decisions
+
+**Cons**:
+- ⚠️ More directories to manage
+- ⚠️ Naming conventions required
+- ⚠️ NO cross-layer links allowed (complexity)
+
+---
+
+## Implementation
+
+**Layer 1: Session Files (`.coder/`)**:
+```
+.coder/
+├── 2026-01-10-agent-coordinator-refactor.plan.md
+├── 2026-01-10-agent-coordinator-refactor.done.md
+├── 2026-01-11-bug-analysis.info.md
+├── 2026-01-12-pr-review.review.md
+└── 2026-01-12-backup-recovery-automation.done.md
+```
+
+**Naming Convention**: `YYYY-MM-DD-description.{plan|done|info|review}.md`
+
+**Content**: Claude Code interaction records, not product documentation.
+
+```markdown
+# Agent Coordinator Refactor - COMPLETED
+
+**Date**: January 10, 2026
+**Status**: ✅ COMPLETE
+**Task**: Refactor agent coordinator to reduce latency
+
+---
+
+## What Was Done
+
+1. Analyzed current coordinator performance
+2. Identified bottleneck: sequential task assignment
+3. Implemented parallel task dispatch
+4. Benchmarked: 50ms → 15ms latency
+
+---
+
+## Key Decisions
+
+- Use `tokio::spawn` for parallel dispatch
+- Keep single source of truth (still in Arc<RwLock>)
+
+## Next Steps
+
+(User's choice)
+```
+
+**Layer 2: Operational Files (`.claude/`)**:
+```

+# VAPORA Architecture Overview
+
+This is permanent product documentation.
+
+## Core Components
+
+- Backend: Axum REST API
+- Frontend: Leptos WASM
+- Database: SurrealDB
+```
+
+**Linking Rules**:
+```
+✅ ALLOWED:
+- docs/ → docs/ (internal links)
+- docs/ → external sites
+- .claude/ → .claude/
+- .coder/ → .coder/
+
+❌ FORBIDDEN:
+- docs/ → .coder/ (product docs can't reference session files)
+- docs/ → .claude/ (product docs shouldn't reference operational files)
+- .coder/ → docs/ (session files can reference product docs though)
+```
+
+**Files and Locations**:
+```rust
+// crates/vapora-backend/src/lib.rs
+//! Product documentation in docs/
+//! Operational guidelines in .claude/guidelines/
+//! Session work in .coder/
+
+// Example in code:
+// See: docs/adrs/0002-axum-backend.md (✅ OK: product doc)
+// See: .claude/guidelines/rust.md (✅ OK: within operational layer)
+// See: .coder/2026-01-10-notes.md (❌ WRONG: session file in product context)
+```
+
+**Documentation Naming**:
+```
+docs/
+├── README.md                  ← UPPERCASE (GitHub convention)
+├── guides/
+│   ├── README.md

+```
+
+**Key Files**:
+- `.claude/CLAUDE.md` (project instructions)
+- `.claude/guidelines/` (language guidelines)
+- `docs/README.md` (documentation index)
+- `docs/adrs/README.md` (ADRs index)
+- `.coder/` (session files)
+
+---
+
+## Verification
+
+```bash
+# Check for broken doc layer links
+grep -r "\.coder" docs/ 2>/dev/null  # Should be empty (❌ if not)
+grep -r "\.claude" docs/ 2>/dev/null # Should be empty (❌ if not)
+
+# Verify session files don't pollute docs/
+ls docs/ | grep -E "^[0-9]"  # Should be empty (❌ if not)
+
+# Check documentation structure
+[ -f docs/README.md ] && echo "✅ docs/README.md exists"
+[ -f .claude/CLAUDE.md ] && echo "✅ .claude/CLAUDE.md exists"
+[ -d .coder ] && echo "✅ .coder directory exists"
+
+# Verify naming conventions
+ls .coder/ | grep -v "^[0-9][0-9][0-9][0-9]-"  # Check format
+```
+
+**Expected Output**:
+- No links from docs/ to .coder/ or .claude/
+- No session files in docs/
+- All documentation layers present
+- Naming conventions followed
+
+---
+
+## Consequences
+
+### Documentation Maintenance
+- Session files: temporary (can be archived/deleted)
+- Operational files: stable (part of Claude Code config)
+- Product docs: permanent (published via mdBook)
+
+### Publication
+- Only `docs/` published to users
+- `.claude/` and `.coder/` never published
+- mdBook builds from docs/ only
+
+### Collaboration
+- Team knows where to find what
+- No confusion between session work and permanent docs
+- Clear ownership: product docs vs operational
+
+### Scaling
+- Add new documents naturally
+- Layer separation doesn't break as project grows
+- mdBook generation automatic
+
+---

+
+## Documentation by Category
+
+### 🗄️ Database & Persistence
+
+- **SurrealDB**: Multi-model database (relational + graph + document) unifies all VAPORA data needs with native multi-tenancy support via scopes
+
+### 🏗️ Core Architecture
+
+- **Workspace**: Monorepo structure with 13 specialized crates enables independent testing, parallel development, code reuse
+- **Backend**: Axum provides composable middleware, type-safe routing, direct Tokio ecosystem integration
+- **Frontend**: Leptos CSR enables fine-grained reactivity and WASM performance (no SEO needed for platform)
+- **LLM Framework**: Rig enables tool calling and streaming with minimal abstraction
+- **Runtime**: Tokio multi-threaded optimized for I/O-heavy workloads (API, DB, LLM calls)
+- **Knowledge Graph**: Temporal history with learning curves enables collective agent learning via SurrealDB
+
+### 🔄 Agent Coordination & Messaging
+
+- **NATS JetStream**: Provides persistent, reliable at-least-once delivery for agent task coordination
+- **Multi-Provider LLM**: Support 4 providers (Claude, OpenAI, Gemini, Ollama) with automatic fallback chain
+
+### ☁️ Infrastructure & Security
+
+- **Istio Service Mesh**: Provides zero-trust security (mTLS), traffic management, observability for inter-service communication
+- **Cedar Authorization**: Declarative, auditable RBAC policies for fine-grained access control
+- **SecretumVault**: Post-quantum cryptography future-proofs API key and credential storage
+- **Three-Tier LLM Routing**: Balances predictability (rules-based) with flexibility (dynamic scoring) and manual override capability
+
+### 🚀 Innovations Unique to VAPORA
+
+- **Learning Profiles**: Recency-biased expertise tracking (3× weight for last 7 days) adapts agent selection to current capability
+- **Budget Enforcement**: Dual time windows (monthly + weekly) with three enforcement states + auto-fallback prevent both long-term and short-term overspend
+- **Cost Efficiency Ranking**: Quality-to-cost formula `(quality_score * 100) / (cost_cents + 1)` prevents overfitting to cheap providers
+- **Confidence Weighting**: `min(1.0, executions/20)` prevents new agents from being selected on lucky streaks
+- **Swarm Load Balancing**: `success_rate / (1 + load)` balances agent expertise with availability
+- **Temporal Execution History**: Daily windowed aggregations identify improvement trends and enable collective learning
+- **Audit Trail**: Complete event logging for compliance, incident investigation, and event sourcing potential
+- **Real-Time WebSocket Updates**: Broadcast channels for efficient multi-client workflow progress updates
+
+### 🔧 Development Patterns
+
+- **Two-Tier Error Handling**: Domain errors (`VaporaError`) separate from HTTP responses (`ApiError`) for reusability
+- **Multi-Layer Testing**: Unit tests (inline) + Integration tests (tests/ dir) + Real database connections = 218+ tests
+- **Service-Oriented Architecture**: Thin API layer delegates to thick services layer containing business logic
+- **Scope-Based Multi-Tenancy**: `tenant_id` fields + SurrealDB scopes provide defense-in-depth tenant isolation
+- **Arc-Based Shared State**: `Arc<RwLock<>>` for read-heavy, `Arc<Mutex<>>` for write-heavy state management
+- **Three-Layer Documentation**: `.coder/` (session) + `.claude/` (operational) + `docs/` (product) separates concerns
+

+
+## How to Use These ADRs
+
+### For Team Members
+
+1. **Understanding Architecture**: Start with Core Architecture ADRs (001-013) to understand technology choices
+2. **Learning VAPORA's Unique Features**: Read Innovations ADRs (014-021) to understand what makes VAPORA different
+3. **Writing New Code**: Reference relevant ADRs in Patterns section (022-027) when implementing features
+
+### For New Hires
+
+1. Read Core Architecture (001-013) first - ~30 minutes to understand the stack
+2. Read Innovations (014-021) - ~45 minutes to understand VAPORA's differentiators
+3. Reference Patterns (022-027) as you write your first contributions
+
+### For Architectural Decisions
+
+When making new architectural decisions:
+
+1. Check existing ADRs to understand previous choices and trade-offs
+2. Create a new ADR following the Custom VAPORA format
+3. Reference existing ADRs that influenced your decision
+4. Get team review before implementation
+
+### For Troubleshooting
+
+When debugging or optimizing:
+
+1. Find the ADR for the relevant component
+2. Review the "Implementation" section for key files
+3. Check "Verification" for testing commands
+4. Review "Consequences" for known limitations
+
+---
+
+## Format
+
+Each ADR follows the Custom VAPORA format:
+
+```markdown
+# ADR-XXX: [Title]
+
+**Status**: Accepted | Implemented
+**Date**: YYYY-MM-DD
+**Deciders**: [Team/Role]
+**Technical Story**: [Context/Issue]
+
+---
+
+## Decision
+[Descripción clara de la decisión]

+
+## References
+[Links a docs, código, issues]
+```
+
+---
+
+## Integration with Project Documentation
+
+- **docs/operations/**: Deployment, disaster recovery, operational runbooks
+- **docs/disaster-recovery/**: Backup strategy, recovery procedures, business continuity
+- **.claude/guidelines/**: Development conventions (Rust, Nushell, Nickel)
+- **.claude/CLAUDE.md**: Project-specific constraints and patterns
+
+---
+
+## Maintenance
+
+### When to Update ADRs
+
+- ❌ Do NOT create new ADRs for minor code changes
+- ✅ DO create ADRs for significant architectural decisions (framework changes, new patterns, major refactoring)
+- ✅ DO update ADRs if a decision changes (mark as "Superseded" and create new ADR)
+
+### Review Process
+
+- ADRs should be reviewed before major architectural changes
+- Use ADRs as reference during code reviews to ensure consistency
+- Update ADRs if they don't reflect current reality (source of truth = code)
+
+### Quarterly Review
+
+- Review all ADRs quarterly to ensure they're still accurate
+- Update "Date" field if reviewed and still valid
+- Mark as "Superseded" if implementation has changed
+
+---
+
+## Statistics
+
+- **Total ADRs**: 27
+- **Core Architecture**: 13 (48%)
+- **Innovations**: 8 (30%)
+- **Patterns**: 6 (22%)
+- **Production Status**: All Accepted and Implemented

+</ul>
+<h3 id="-core-architecture"><a class="header" href="#-core-architecture">🏗️ Core Architecture</a></h3>
+<ul>
+<li><strong>Workspace</strong>: Monorepo structure with 13 specialized crates enables independent testing, parallel development, code reuse</li>
+<li><strong>Backend</strong>: Axum provides composable middleware, type-safe routing, direct Tokio ecosystem integration</li>
+<li><strong>Frontend</strong>: Leptos CSR enables fine-grained reactivity and WASM performance (no SEO needed for platform)</li>
+<li><strong>LLM Framework</strong>: Rig enables tool calling and streaming with minimal abstraction</li>
+<li><strong>Runtime</strong>: Tokio multi-threaded optimized for I/O-heavy workloads (API, DB, LLM calls)</li>

+<h3 id="-innovations-unique-to-vapora"><a class="header" href="#-innovations-unique-to-vapora">🚀 Innovations Unique to VAPORA</a></h3>
+<ul>
+<li><strong>Learning Profiles</strong>: Recency-biased expertise tracking (3× weight for last 7 days) adapts agent selection to current capability</li>
+<li><strong>Budget Enforcement</strong>: Dual time windows (monthly + weekly) with three enforcement states + auto-fallback prevent both long-term and short-term overspend</li>
+<li><strong>Cost Efficiency Ranking</strong>: Quality-to-cost formula <code>(quality_score * 100) / (cost_cents + 1)</code> prevents overfitting to cheap providers</li>
+<li><strong>Confidence Weighting</strong>: <code>min(1.0, executions/20)</code> prevents new agents from being selected on lucky streaks</li>

+<li><strong>Audit Trail</strong>: Complete event logging for compliance, incident investigation, and event sourcing potential</li>
+<li><strong>Real-Time WebSocket Updates</strong>: Broadcast channels for efficient multi-client workflow progress updates</li>
+</ul>
+<h3 id="-development-patterns"><a class="header" href="#-development-patterns">🔧 Development Patterns</a></h3>
+<ul>
+<li><strong>Two-Tier Error Handling</strong>: Domain errors (<code>VaporaError</code>) separate from HTTP responses (<code>ApiError</code>) for reusability</li>
+<li><strong>Multi-Layer Testing</strong>: Unit tests (inline) + Integration tests (tests/ dir) + Real database connections = 218+ tests</li>
+<li><strong>Service-Oriented Architecture</strong>: Thin API layer delegates to thick services layer containing business logic</li>
+<li><strong>Scope-Based Multi-Tenancy</strong>: <code>tenant_id</code> fields + SurrealDB scopes provide defense-in-depth tenant isolation</li>
+<li><strong>Arc-Based Shared State</strong>: <code>Arc&lt;RwLock&lt;&gt;&gt;</code> for read-heavy, <code>Arc&lt;Mutex&lt;&gt;&gt;</code> for write-heavy state management</li>

+<h3 id="adr-template"><a class="header" href="#adr-template">ADR Template</a></h3>
+<pre><code class="language-markdown"># ADR-042: Learning-Based Agent Selection
+
+## Context
+
+Previous agent assignment used simple load balancing (min tasks),
+ignoring historical performance data. This led to poor agent-task matches.
+
+## Decision
+
+Implement per-task-type learning profiles with recency bias.
+
+### Key Points
+- Success rate weighted by recency (7-day window, 3× weight)
+- Confidence scoring prevents small-sample overfitting
+- Supports adaptive recovery from temporary degradation
+
+## Consequences
+
+**Positive**:
+- 30-50% improvement in task success rate
+- Agents improve continuously
+
+**Negative**:
+- Requires KG data collection (startup period)
+- Learning period ~20 tasks per task-type
+
+## Alternatives Considered
+
+1. Rule-based routing (rejected: no learning)
+2. Pure random assignment (rejected: no improvement)
+3. Rolling average (rejected: no recency bias)
+
+## Decision Made
+
+Option A: Learning profiles with recency bias

+   - Load balancing (success_rate / (1 + load))
+   - Scoring: 0.3*load + 0.5*expertise + 0.2*confidence

+
+## Common Questions
+
+### Q: How often are backups taken
+
+**A**: Hourly for database (1-hour RPO), daily for configs/IaC. Monthly restore tests verify backups work.
+
+### Q: How long does recovery take
+
+**A**: Depends on scenario. Pod restart: 2-3 min. Database recovery: 15-60 min. Full cluster: 2-4 hours.
+
+### Q: How much data can we lose
+
+**A**: Maximum 1 hour (RPO = 1 hour). Worst case: lose transactions from last hour.
+
+### Q: Are backups encrypted
+
+**A**: Yes. All backups use AES-256 encryption at rest. Stored in S3 with separate access keys.
+
+### Q: How do we know backups work
+
+**A**: Monthly restore tests. We download a backup, restore to test database, and verify data integrity.
+
+### Q: What if the backup location fails
+
+**A**: We have secondary backups in different region. Plus monthly archive copies to cold storage.
+
+### Q: Who runs the disaster recovery
+
+**A**: Incident Commander (assigned during incident) directs response. Team follows procedures in runbooks.
+
+### Q: When is the next DR drill
+
+**A**: Quarterly on last Friday of each quarter at 02:00 UTC. See [Business Continuity Plan § Test Schedule](./business-continuity-plan.md).
+

+
+## Support & Escalation
+
+### If You Find an Issue
+
+1. **Document the problem**
+   - What happened?
+   - When did it happen?
+   - How did you find it?
+
+2. **Check the runbooks**
+   - Is it covered in procedures?
+   - Try recommended solution
+
+3. **Escalate if needed**
+   - Ask in #incident-critical
+   - Page on-call engineer for critical issues
+
+4. **Update documentation**
+   - If procedure unclear, suggest improvement
+   - Submit PR to update runbooks

+# VAPORA Backup Strategy
+
+Comprehensive backup and data protection strategy for VAPORA infrastructure.
+
+---
+
+## Overview
+
+**Purpose**: Protect against data loss, corruption, and service interruptions
+
+**Coverage**:
+- Database backups (SurrealDB)
+- Configuration backups (ConfigMaps, Secrets)
+- Application state
+- Infrastructure-as-Code
+- Container images
+
+**Success Metrics**:
+- RPO (Recovery Point Objective): 1 hour (lose at most 1 hour of data)
+- RTO (Recovery Time Objective): 4 hours (restore service within 4 hours)
+- Backup availability: 99.9% (backups always available when needed)
+- Backup validation: 100% (all backups tested monthly)
+
+---
+
+## Backup Architecture
+
+### What Gets Backed Up
+
+```
+VAPORA Backup Scope
+
+Critical (Daily):
+├── Database
+│   ├── SurrealDB data
+│   ├── User data
+│   ├── Project/task data
+│   └── Audit logs
+├── Configuration
+│   ├── ConfigMaps
+│   ├── Secrets
+│   └── Deployment manifests
+└── Infrastructure Code
+    ├── Provisioning/Nickel configs
+    ├── Kubernetes manifests
+    └── Scripts
+
+Important (Weekly):
+├── Application logs
+├── Metrics data
+└── Documentation updates
+
+Optional (As-needed):
+├── Container images
+├── Build artifacts
+└── Development configurations
+```
+
+### Backup Storage Strategy
+
+```
+PRIMARY BACKUP LOCATION
+├── Storage: Cloud object storage (S3/GCS/Azure Blob)
+├── Frequency: Hourly for database, daily for configs
+├── Retention: 30 days rolling window
+├── Encryption: AES-256 at rest
+└── Redundancy: Geo-replicated to different region
+
+SECONDARY BACKUP LOCATION (for critical data)
+├── Storage: Different cloud provider or on-prem
+├── Frequency: Daily
+├── Retention: 90 days
+├── Purpose: Protection against primary provider outage
+└── Testing: Restore tested weekly
+
+ARCHIVE LOCATION (compliance/long-term)
+├── Storage: Cold storage (Glacier, Azure Archive)
+├── Frequency: Monthly
+├── Retention: 7 years (adjust per compliance needs)
+├── Purpose: Compliance & legal holds
+└── Accessibility: ~4 hours to retrieve
+```
+
+---
+
+## Database Backup Procedures
+
+### SurrealDB Backup
+
+**Backup Method**: Full database dump via SurrealDB export
+
+```bash
+# Export full database
+kubectl exec -n vapora surrealdb-pod -- \
+  surreal export --conn ws://localhost:8000 \
+  --user root \
+  --pass "$DB_PASSWORD" \
+  --output backup-$(date +%Y%m%d-%H%M%S).sql
+
+# Expected size: 100MB-1GB (depending on data)
+# Expected time: 5-15 minutes
+```
+
+**Automated Backup Setup**
+
+```bash
+# Create backup script: provisioning/scripts/backup-database.nu
+def backup_database [output_dir: string] {
+  let timestamp = (date now | format date %Y%m%d-%H%M%S)
+  let backup_file = $"($output_dir)/vapora-db-($timestamp).sql"
+
+  print $"Starting database backup to ($backup_file)..."
+
+  # Export database
+  kubectl exec -n vapora deployment/vapora-backend -- \
+    surreal export \
+      --conn ws://localhost:8000 \
+      --user root \
+      --pass $env.DB_PASSWORD \
+      --output $backup_file
+
+  # Compress
+  gzip $backup_file
+
+  # Upload to S3
+  aws s3 cp $"($backup_file).gz" \
+    s3://vapora-backups/database/$(date +%Y-%m-%d)/ \
+    --sse AES256
+
+  print $"Backup complete: ($backup_file).gz"
+}
+```
+
+**Backup Schedule**
+
+```yaml
+# Kubernetes CronJob for hourly backups
+apiVersion: batch/v1
+kind: CronJob
+metadata:
+  name: database-backup
+  namespace: vapora
+spec:
+  schedule: "0 * * * *"  # Every hour
+  jobTemplate:
+    spec:
+      template:
+        spec:
+          containers:
+          - name: backup
+            image: vapora/backup-tools:latest
+            command:
+            - /scripts/backup-database.sh
+            env:
+            - name: DB_PASSWORD
+              valueFrom:
+                secretKeyRef:
+                  name: db-credentials
+                  key: password
+            - name: AWS_ACCESS_KEY_ID
+              valueFrom:
+                secretKeyRef:
+                  name: aws-credentials
+                  key: access-key
+          restartPolicy: OnFailure
+```
+
+### Backup Retention Policy
+
+```
+Hourly backups (last 24 hours):
+├── Keep: All hourly backups
+├── Purpose: Granular recovery options
+└── Storage: Standard (fast access)
+
+Daily backups (last 30 days):
+├── Keep: 1 per day at midnight UTC
+├── Purpose: Daily recovery options
+└── Storage: Standard (fast access)
+
+Weekly backups (last 90 days):
+├── Keep: 1 per Sunday at midnight UTC
+├── Purpose: Medium-term recovery
+└── Storage: Standard
+
+Monthly backups (7 years):
+├── Keep: 1 per month on 1st at midnight UTC
+├── Purpose: Compliance & long-term recovery
+└── Storage: Archive (cold storage)
+```
+
+### Backup Verification
+
+```bash
+# Daily backup verification
+def verify_backup [backup_file: string] {
+  print $"Verifying backup: ($backup_file)"
+
+  # 1. Check file integrity
+  if (not (file exists $backup_file)) {

+  }
+
+  # 3. Check file header (should contain SQL dump)
+  let header = (open -r $backup_file | first 10)
+  if (not ($header | str contains "SURREALDB")) {
+    error make {msg: "Invalid backup format"}
+  }
+
+  print "✓ Backup verified successfully"

+
+  # 5. Cleanup test database
+  kubectl delete pod -n vapora test-db
+
+  print "✓ Restore test passed"
+}
+```
+
+---
+
+## Configuration Backup
+
+### ConfigMap & Secret Backups
+
+```bash
+# Backup all ConfigMaps
+kubectl get configmap -n vapora -o yaml > configmaps-backup-$(date +%Y%m%d).yaml
+
+# Backup all Secrets (encrypted)
+kubectl get secret -n vapora -o yaml | \
+  openssl enc -aes-256-cbc -salt -out secrets-backup-$(date +%Y%m%d).yaml.enc
+
+# Upload to S3
+aws s3 sync . s3://vapora-backups/k8s-configs/$(date +%Y-%m-%d)/ \
+  --exclude "*" --include "*.yaml" --include "*.yaml.enc" \
+  --sse AES256
+```
+
+**Automated Nushell Script**
+
+```nushell
+def backup_k8s_configs [output_dir: string] {
+  let timestamp = (date now | format date %Y%m%d)
+  let config_dir = $"($output_dir)/k8s-configs-($timestamp)"
+
+  mkdir $config_dir
+
+  # Backup ConfigMaps
+  kubectl get configmap -n vapora -o yaml > $"($config_dir)/configmaps.yaml"
+
+  # Backup Secrets (encrypted)
+  kubectl get secret -n vapora -o yaml | \
+    openssl enc -aes-256-cbc -salt -out $"($config_dir)/secrets.yaml.enc"
+
+  # Backup Deployments
+  kubectl get deployments -n vapora -o yaml > $"($config_dir)/deployments.yaml"
+
+  # Backup Services
+  kubectl get services -n vapora -o yaml > $"($config_dir)/services.yaml"
+
+  # Backup all to archive
+  tar -czf $"($config_dir).tar.gz" $config_dir
+
+  # Upload

+    s3://vapora-backups/configs/ \
+    --sse AES256
+
+  print "✓ K8s configs backed up"
+}
+```
+
+---
+
+## Infrastructure-as-Code Backups
+
+### Git Repository Backups
+
+**Primary**: GitHub (with backup organization)
+
+```bash
+# Mirror repository to backup location
+git clone --mirror https://github.com/your-org/vapora.git \
+  vapora-mirror.git
+
+# Push to backup location
+cd vapora-mirror.git
+git push --mirror https://backup-git-server/vapora-mirror.git
+```
+
+**Backup Schedule**
+
+```yaml
+# Daily mirror push
+*/6 * * * * /scripts/backup-git-repo.sh
+```
+
+### Provisioning Code Backups
+
+```bash
+# Backup Nickel configs & scripts
+def backup_provisioning_code [output_dir: string] {
+  let timestamp = (date now | format date %Y%m%d)
+
+  # Create backup
+  tar -czf $"($output_dir)/provisioning-($timestamp).tar.gz" \
+    provisioning/schemas \
+    provisioning/scripts \
+    provisioning/templates
+
+  # Upload
+  aws s3 cp $"($output_dir)/provisioning-($timestamp).tar.gz" \
+    s3://vapora-backups/provisioning/ \
+    --sse AES256
+}
+```
+
+---
+
+## Application State Backups
+
+### Persistent Volume Backups
+
+If using persistent volumes for data:
+
+```bash
+# Backup PersistentVolumeClaims
+def backup_pvcs [namespace: string] {
+  let pvcs = (kubectl get pvc -n $namespace -o json | from json).items
+
+  for pvc in $pvcs {
+    let pvc_name = $pvc.metadata.name
+    let volume_size = $pvc.spec.resources.requests.storage
+
+    print $"Backing up PVC: ($pvc_name) (($volume_size))"
+
+    # Create snapshot (cloud-specific)
+    aws ec2 create-snapshot \
+      --volume-id $pvc_name \
+      --description $"VAPORA backup $(date +%Y-%m-%d)"
+  }
+}
+```
+
+### Application Logs
+
+```bash
+# Export logs for archive
+def backup_application_logs [output_dir: string] {
+  let timestamp = (date now | format date %Y%m%d)
+
+  # Export last 7 days of logs
+  kubectl logs deployment/vapora-backend -n vapora \
+    --since=168h > $"($output_dir)/backend-logs-($timestamp).log"
+
+  kubectl logs deployment/vapora-agents -n vapora \
+    --since=168h > $"($output_dir)/agents-logs-($timestamp).log"
+
+  # Compress and upload
+  gzip $"($output_dir)/*.log"
+  aws s3 sync $output_dir s3://vapora-backups/logs/ \
+    --exclude "*" --include "*.log.gz" \
+    --sse AES256
+}
+```
+
+---
+
+## Container Image Backups
+
+### Docker Image Registry
+
+```bash
+# Tag images for backup
+docker tag vapora/backend:latest vapora/backend:backup-$(date +%Y%m%d)
+docker tag vapora/agents:latest vapora/agents:backup-$(date +%Y%m%d)
+docker tag vapora/llm-router:latest vapora/llm-router:backup-$(date +%Y%m%d)

+### Backup Health Checks
+
+```bash
+# Daily backup status check
+def check_backup_status [] {
+  print "=== Backup Status Report ==="
+
+  # 1. Check latest database backup
+  let latest_db = (aws s3 ls s3://vapora-backups/database/ \

+```
+
+### Backup Alerts
+
+Configure alerts for:
+
+```yaml
+Backup Failures:
+  - Threshold: Backup not completed in 2 hours
+  - Action: Alert operations team
+  - Severity: High
+
+Backup Staleness:
+  - Threshold: Latest backup > 24 hours old
+  - Action: Alert operations team
+  - Severity: High
+
+Storage Capacity:
+  - Threshold: Backup storage > 80% full
+  - Action: Alert & plan cleanup
+  - Severity: Medium
+
+Restore Test Failures:
+  - Threshold: Monthly restore test fails
+  - Action: Alert & investigate
+  - Severity: Critical
+```
+
+---
+
+## Backup Testing & Validation
+
+### Monthly Restore Test
+
+**Schedule**: First Sunday of each month at 02:00 UTC
+
+```bash
+def monthly_restore_test [] {
+  print "Starting monthly restore test..."
+
+  # 1. Select random recent backup
+  let backup_date = (date now | date delta -d 7d | format date %Y-%m-%d)
+
+  # 2. Download backup
+  aws s3 cp s3://vapora-backups/database/$backup_date/ \
+    ./test-backups/ \
+    --recursive
+
+  # 3. Restore to test environment
+  # (See Database Recovery Procedures)
+
+  # 4. Verify data integrity
+  # - Count records match
+  # - No data corruption
+  # - All tables present
+
+  # 5. Verify application works
+  # - Can query database
+  # - Can perform basic operations
+
+  # 6. Document results
+  # - Success/failure
+  # - Any issues found
+  # - Time taken
+
+  print "✓ Restore test completed"
+}
+```
+
+### Backup Audit Report
+
+**Quarterly**: Generate backup audit report
+
+```bash
+def quarterly_backup_audit [] {
+  print "=== Quarterly Backup Audit Report ==="
+  print $"Report Date: (date now | format date %Y-%m-%d)"
+  print ""
+
+  print "1. Backup Coverage"

+  print "   Configs: Daily ✓"
+  print "   IaC: Daily ✓"
+  print ""
+
+  print "2. Restore Tests (Last Quarter)"
+  print "   Tests Performed: 3"
+  print "   Tests Passed: 3"
+  print "   Average Restore Time: 2.5 hours"
+  print ""
+
+  print "3. Storage Usage"
+  # Calculate storage per category

+}
+```
+

+
+## Backup Security
+
+### Encryption
+
+- ✅ All backups encrypted at rest (AES-256)
+- ✅ All backups encrypted in transit (HTTPS/TLS)
+- ✅ Encryption keys managed by cloud provider or KMS
+- ✅ Separate keys for database and config backups
+
+### Access Control
+
+```
+Backup Access Policy:
+
+Read Access:
+  - Operations team
+  - Disaster recovery team
+  - Compliance/audit team
+
+Write Access:
+  - Automated backup system only
+  - Require 2FA for manual backups
+
+Delete/Modify Access:
+  - Require 2 approvals
+  - Audit logging enabled
+  - 24-hour delay before deletion
+```
+
+### Audit Logging
+
+```bash
+# All backup operations logged
+- Backup creation: When, size, hash
+- Backup retrieval: Who, when, what
+- Restore operations: When, who, from where
+- Backup deletion: When, who, reason
+
+# Logs stored separately and immutable
+# Example: CloudTrail, S3 access logs, custom logging
+```
+
+---
+
+## Backup Disaster Scenarios
+
+### Scenario 1: Single Database Backup Fails
+
+**Impact**: 1-hour data loss risk
+
+**Prevention**:
+- Backup redundancy (multiple copies)
+- Multiple backup methods
+- Backup validation after each backup
+
+**Recovery**:
+- Use previous hour's backup
+- Restore to test environment first
+- Validate data integrity
+- Restore to production if good
+
+### Scenario 2: Backup Storage Compromised
+
+**Impact**: Data loss + security breach
+
+**Prevention**:
+- Encryption with separate keys
+- Geographic redundancy
+- Backup verification signing
+- Access control restrictions
+
+**Recovery**:
+- Activate secondary backup location
+- Restore from archive backups
+- Full security audit
+
+### Scenario 3: Ransomware Infection
+
+**Impact**: All recent backups encrypted
+
+**Prevention**:
+- Immutable backups (WORM)
+- Air-gapped backups (offline)
+- Archive-only old backups
+- Regular backup verification
+
+**Recovery**:
+- Use air-gapped backup
+- Restore to clean environment
+- Full security remediation
+
+### Scenario 4: Accidental Data Deletion
+
+**Impact**: Data loss from point of deletion
+
+**Prevention**:
+- Frequent backups (hourly)
+- Soft deletes in application
+- Audit logging
+
+**Recovery**:
+- Restore from backup before deletion time
+- Point-in-time recovery if available
+
+---
+

+# VAPORA Business Continuity Plan
+
+Strategic plan for maintaining business operations during and after disaster events.
+
+---
+
+## Purpose & Scope
+
+**Purpose**: Minimize business impact during service disruptions
+
+**Scope**:
+- Service availability targets
+- Incident response procedures
+- Communication protocols
+- Recovery priorities
+- Business impact assessment
+
+**Owner**: Operations Team
+**Review Frequency**: Quarterly
+**Last Updated**: 2026-01-12
+
+---
+
+## Business Impact Analysis
+
+### Service Criticality
+
+**Tier 1 - Critical**:
+- Backend API (projects, tasks, agents)
+- SurrealDB (all user data)
+- Authentication system
+- Health monitoring
+
+**Tier 2 - Important**:
+- Frontend UI
+- Agent orchestration
+- LLM routing
+
+**Tier 3 - Optional**:
+- Analytics
+- Logging aggregation
+- Monitoring dashboards
+
+### Recovery Priorities
+
+**Phase 1** (First 30 minutes):
+1. Backend API availability
+2. Database connectivity
+3. User authentication
+
+**Phase 2** (Next 30 minutes):
+4. Frontend UI access
+5. Agent services
+6. Core functionality
+
+**Phase 3** (Next 2 hours):
+7. All features
+8. Monitoring/alerting
+9. Analytics/logging
+
+---
+
+## Service Level Targets

+
+## Scenario 1: Pod Restart (Most Common)
+
+**Cause**: Node maintenance, resource limits, health check failure
+
+**Duration**: 2-3 minutes
+**Data Loss**: None
+
+### Recovery Procedure
+
+```bash
+# Most of the time, just restart the pod
+
+# 1. Delete the pod
+kubectl delete pod -n vapora surrealdb-0
+
+# 2. Pod automatically restarts (via StatefulSet)
+kubectl get pods -n vapora -w
+
+# 3. Verify it's Ready
+kubectl get pod surrealdb-0 -n vapora
+# Should show: 1/1 Running
+
+# 4. Verify database is accessible
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT 1"
+
+# 5. Check data integrity
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+# Should return non-zero count
+```
+
+---
+
+## Scenario 2: Pod CrashLoop (Container Issue)
+
+**Cause**: Application crash, memory issues, corrupt index
+
+**Duration**: 5-10 minutes
+**Data Loss**: None (usually)
+
+### Recovery Procedure
+
+```bash
+# 1. Examine pod logs to identify issue
+kubectl logs surrealdb-0 -n vapora --previous
+# Look for: "panic", "fatal", "out of memory"
+
+# 2. Increase resource limits if memory issue
+kubectl patch statefulset surrealdb -n vapora --type='json' \
+  -p='[{"op": "replace", "path": "/spec/template/spec/containers/0/resources/limits/memory", "value":"2Gi"}]'
+
+# 3. If corrupt index, rebuild
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal query "REBUILD INDEX"
+
+# 4. If persistent issue, try volume snapshot
+kubectl delete pod -n vapora surrealdb-0
+# Use previous snapshot (if available)
+
+# 5. Monitor restart
+kubectl get pods -n vapora -w
+```
+
+---
+
+## Scenario 3: Corrupted Database (Detected via Queries)
+
+**Cause**: Unclean shutdown, disk issue, data corruption
+
+**Duration**: 15-30 minutes
+**Data Loss**: Minimal (last hour of transactions)
+
+### Detection
+
+```bash
+# Symptoms to watch for
+✗ Queries return error: "corrupted database"
+✗ Disk check shows corruption
+✗ Checksums fail
+✗ Integrity check fails
+
+# Verify corruption
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal query "INFO FOR DB"
+# Look for any error messages
+
+# Try repair
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal query "REBUILD INDEX"
+```
+
+### Recovery: Option A - Restart and Repair (Try First)
+
+```bash
+# 1. Delete pod to force restart
+kubectl delete pod -n vapora surrealdb-0
+
+# 2. Watch restart
+kubectl get pods -n vapora -w
+# Should restart within 30 seconds
+
+# 3. Verify database accessible
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+
+# 4. If successful, done
+# If still errors, proceed to Option B
+```
+
+### Recovery: Option B - Restore from Recent Backup
+
+```bash
+# 1. Stop database pod
+kubectl scale statefulset surrealdb --replicas=0 -n vapora
+
+# 2. Download latest backup
+aws s3 cp s3://vapora-backups/database/ ./ --recursive
+# Get most recent .sql.gz file
+
+# 3. Clear corrupted data
+kubectl delete pvc -n vapora surrealdb-data-surrealdb-0
+
+# 4. Recreate pod (will create new PVC)
+kubectl scale statefulset surrealdb --replicas=1 -n vapora
+
+# 5. Wait for pod to be ready
+kubectl wait --for=condition=Ready pod/surrealdb-0 \
+  -n vapora --timeout=300s
+
+# 6. Restore backup
+# Extract and import
+gunzip vapora-db-*.sql.gz
+kubectl cp vapora-db-*.sql vapora/surrealdb-0:/tmp/
+
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal import \
+    --conn ws://localhost:8000 \
+    --user root \
+    --pass $DB_PASSWORD \
+    --input /tmp/vapora-db-*.sql
+
+# 7. Verify restored data
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+# Should match pre-corruption count
+```
+
+---
+
+## Scenario 4: Storage Failure (PVC Issue)
+
+**Cause**: Storage volume corruption, node storage failure
+
+**Duration**: 20-30 minutes
+**Data Loss**: None with backup
+
+### Recovery Procedure
+
+```bash
+# 1. Detect storage issue
+kubectl describe pvc -n vapora surrealdb-data-surrealdb-0
+# Look for: "Pod pending", "volume binding failure"
+
+# 2. Check if snapshot available (cloud)
+aws ec2 describe-snapshots \
+  --filters "Name=tag:database,Values=vapora" \
+  --query 'Snapshots[].{SnapshotId:SnapshotId,StartTime:StartTime}' \
+  --sort-by StartTime | tail -10
+
+# 3. Create new PVC from snapshot
+kubectl apply -f - << EOF
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: surrealdb-data-surrealdb-0-restore
+  namespace: vapora
+spec:
+  accessModes:
+    - ReadWriteOnce
+  dataSource:
+    kind: VolumeSnapshot
+    apiGroup: snapshot.storage.k8s.io
+    name: surrealdb-snapshot-latest
+  resources:
+    requests:
+      storage: 100Gi
+EOF
+
+# 4. Update StatefulSet to use new PVC
+kubectl patch statefulset surrealdb -n vapora --type='json' \
+  -p='[{"op": "replace", "path": "/spec/volumeClaimTemplates/0/metadata/name", "value":"surrealdb-data-surrealdb-0-restore"}]'
+
+# 5. Delete old pod to force remount
+kubectl delete pod -n vapora surrealdb-0
+
+# 6. Verify new pod runs
+kubectl get pods -n vapora -w
+
+# 7. Test database
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+```
+
+---
+
+## Scenario 5: Complete Data Loss (Restore from Backup)
+
+**Cause**: User delete, accidental truncate, security incident
+
+**Duration**: 30-60 minutes
+**Data Loss**: Up to 1 hour
+
+### Pre-Recovery Checklist
+
+```
+Before restoring, verify:
+□ What data was lost? (specific tables or entire DB?)
+□ When was it lost? (exact time if possible)
+□ Is it just one table or entire database?
+□ Do we have valid backups from before loss?
+□ Has the backup been tested before?
+```
+
+### Recovery Procedure
+
+```bash
+# 1. Stop the database
+kubectl scale statefulset surrealdb --replicas=0 -n vapora
+sleep 10
+
+# 2. Identify backup to restore
+# Look for backup from time BEFORE data loss
+aws s3 ls s3://vapora-backups/database/ --recursive | sort
+# Example: surrealdb-2026-01-12-230000.sql.gz
+# (from 11 PM, before 12 AM loss)
+
+# 3. Download backup
+aws s3 cp s3://vapora-backups/database/2026-01-12-surrealdb-230000.sql.gz ./
+
+gunzip surrealdb-230000.sql
+
+# 4. Verify backup integrity before restoring
+# Extract first 100 lines to check format
+head -100 surrealdb-230000.sql
+
+# 5. Delete corrupted PVC
+kubectl delete pvc -n vapora surrealdb-data-surrealdb-0
+
+# 6. Restart database pod (will create new PVC)
+kubectl scale statefulset surrealdb --replicas=1 -n vapora
+
+# 7. Wait for pod to be ready and listening
+kubectl wait --for=condition=Ready pod/surrealdb-0 \
+  -n vapora --timeout=300s
+sleep 10
+
+# 8. Copy backup to pod
+kubectl cp surrealdb-230000.sql vapora/surrealdb-0:/tmp/
+
+# 9. Restore backup
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal import \
+    --conn ws://localhost:8000 \
+    --user root \
+    --pass $DB_PASSWORD \
+    --input /tmp/surrealdb-230000.sql
+
+# Expected output:
+# Imported 1500+ records...
+# This should take 5-15 minutes depending on backup size
+
+# 10. Verify data restored
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql \
+    --conn ws://localhost:8000 \
+    --user root \
+    --pass $DB_PASSWORD \
+    "SELECT COUNT(*) as project_count FROM projects"
+
+# Should match pre-loss count
+```
+
+### Data Loss Assessment
+
+```bash
+# After restore, compare with lost version
+
+# 1. Get current record count
+RESTORED_COUNT=$(kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects")
+
+# 2. Get pre-loss count (from logs or ticket)
+PRE_LOSS_COUNT=1500
+
+# 3. Calculate data loss
+if [ "$RESTORED_COUNT" -lt "$PRE_LOSS_COUNT" ]; then
+  LOSS=$(( PRE_LOSS_COUNT - RESTORED_COUNT ))
+  echo "Data loss: $LOSS records"
+  echo "Data loss duration: ~1 hour"
+  echo "Restore successful but incomplete"
+else
+  echo "Data loss: 0 records"
+  echo "Full recovery complete"
+fi
+```
+
+---
+
+## Scenario 6: Backup Verification Failed
+
+**Cause**: Corrupt backup file, incompatible format
+
+**Duration**: 30-120 minutes (fallback to older backup)
+**Data Loss**: 2+ hours possible
+
+### Recovery Procedure
+
+```bash
+# 1. Identify backup corruption
+# During restore, if backup fails import:
+
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal import \
+    --conn ws://localhost:8000 \
+    --user root \
+    --pass $DB_PASSWORD \
+    --input /tmp/backup.sql
+
+# Error: "invalid SQL format" or similar
+
+# 2. Check backup file integrity
+file vapora-db-backup.sql
+# Should show: ASCII text
+
+head -5 vapora-db-backup.sql
+# Should show: SQL statements or surreal export format
+
+# 3. If corrupt, try next-oldest backup
+aws s3 ls s3://vapora-backups/database/ --recursive | sort | tail -5
+# Get second-newest backup
+
+# 4. Retry restore with older backup
+aws s3 cp s3://vapora-backups/database/2026-01-12-210000/ ./
+gunzip backup.sql.gz
+
+# 5. Repeat restore procedure with older backup
+# (As in Scenario 5, steps 8-10)
+```
+
+---
+
+## Scenario 7: Database Size Growing Unexpectedly
+
+**Cause**: Accumulation of data, logs not rotated, storage leak
+
+**Duration**: Varies (prevention focus)
+**Data Loss**: None
+
+### Detection
+
+```bash
+# Monitor database size
+kubectl exec -n vapora surrealdb-0 -- du -sh /var/lib/surrealdb/
+
+# Check disk usage trend
+# (Should be ~1-2% growth per week)
+
+# If sudden spike:
+kubectl exec -n vapora surrealdb-0 -- \
+  find /var/lib/surrealdb/ -type f -exec ls -lh {} + | sort -k5 -h | tail -20
+```
+
+### Cleanup Procedure
+
+```bash
+# 1. Identify large tables
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT table, count(*) FROM meta::tb GROUP BY table ORDER BY count DESC"
+
+# 2. If logs table too large
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "DELETE FROM audit_logs WHERE created_at < now() - 90d"
+
+# 3. Rebuild indexes to reclaim space
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal query "REBUILD INDEX"
+
+# 4. If still large, delete old records from other tables
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "DELETE FROM tasks WHERE status = 'archived' AND updated_at < now() - 1y"
+
+# 5. Monitor size after cleanup
+kubectl exec -n vapora surrealdb-0 -- du -sh /var/lib/surrealdb/
+```
+
+---
+
+## Scenario 8: Replication Lag (If Using Replicas)
+
+**Cause**: Replica behind primary, network latency
+
+**Duration**: Usually self-healing (seconds to minutes)
+**Data Loss**: None
+
+### Detection
+
+```bash
+# Check replica lag
+kubectl exec -n vapora surrealdb-replica -- \
+  surreal sql "SHOW REPLICATION STATUS"
+
+# Look for: "Seconds_Behind_Master" > 5 seconds
+```
+
+### Recovery
+
+```bash
+# Usually self-healing, but if stuck:
+
+# 1. Check network connectivity
+kubectl exec -n vapora surrealdb-replica -- ping surrealdb-primary -c 5
+
+# 2. Restart replica
+kubectl delete pod -n vapora surrealdb-replica
+
+# 3. Monitor replica catching up
+kubectl logs -n vapora surrealdb-replica -f
+
+# 4. Verify replica status
+kubectl exec -n vapora surrealdb-replica -- \
+  surreal sql "SHOW REPLICATION STATUS"
+```
+
+---
+
+## Database Health Checks
+
+### Pre-Recovery Verification
+
+```bash
+def verify_database_health [] {
+  print "=== Database Health Check ==="
+
+  # 1. Connection test
+  let conn = (try (
+    exec "surreal sql --conn ws://localhost:8000 \"SELECT 1\""
+  ) catch {error make {msg: "Cannot connect to database"}})
+
+  # 2. Data integrity test
+  let integrity = (exec "surreal sql \"REBUILD INDEX\"")
+  print "✓ Integrity check passed"
+
+  # 3. Performance test
+  let perf = (exec "surreal sql \"SELECT COUNT(*) FROM projects\"")
+  print "✓ Performance acceptable"
+
+  # 4. Replication lag (if applicable)
+  # let lag = (exec "surreal sql \"SHOW REPLICATION STATUS\"")
+  # print "✓ No replication lag"
+
+  print "✓ All health checks passed"
+}
+```
+
+### Post-Recovery Verification
+
+```bash
+def verify_recovery_success [] {
+  print "=== Post-Recovery Verification ==="
+
+  # 1. Database accessible
+  kubectl exec -n vapora surrealdb-0 -- \
+    surreal sql "SELECT 1"
+  print "✓ Database accessible"
+
+  # 2. All tables present
+  kubectl exec -n vapora surrealdb-0 -- \
+    surreal sql "SELECT table FROM meta::tb"
+  print "✓ All tables present"
+
+  # 3. Record counts reasonable
+  kubectl exec -n vapora surrealdb-0 -- \
+    surreal sql "SELECT table, count(*) FROM meta::tb"
+  print "✓ Record counts verified"
+
+  # 4. Application can connect
+  kubectl logs -n vapora deployment/vapora-backend --tail=5 | grep -i connected
+  print "✓ Application connected"
+
+  # 5. API operational
+  curl http://localhost:8001/api/projects
+  print "✓ API operational"
+}
+```
+
+---
+
+## Database Recovery Checklist
+
+### Before Recovery
+
+```
+□ Documented failure symptoms
+□ Determined root cause
+□ Selected appropriate recovery method
+□ Located backup to restore
+□ Verified backup integrity
+□ Notified relevant teams
+□ Have runbook available
+□ Test environment ready (for testing)
+```
+
+### During Recovery
+
+```
+□ Followed procedure step-by-step
+□ Monitored each step completion
+□ Captured any error messages
+□ Took notes of timings
+□ Did NOT skip verification steps
+□ Had backup plans ready
+```
+
+### After Recovery
+
+```
+□ Verified database accessible
+□ Verified data integrity
+□ Verified application can connect
+□ Checked API endpoints working
+□ Monitored error rates
+□ Waited for 30 min stability check
+□ Documented recovery procedure
+□ Identified improvements needed
+□ Updated runbooks if needed
+```
+
+---
+
+## Recovery Troubleshooting
+
+### Issue: "Cannot connect to database after restore"
+
+**Cause**: Database not fully recovered, network issue
+
+**Solution**:
+```bash
+# 1. Wait longer (import can take 15+ minutes)
+sleep 60 && kubectl exec -n vapora surrealdb-0 -- surreal sql "SELECT 1"
+
+# 2. Check pod logs
+kubectl logs -n vapora surrealdb-0 | tail -50
+
+# 3. Restart pod
+kubectl delete pod -n vapora surrealdb-0
+
+# 4. Check network connectivity
+kubectl exec -n vapora surrealdb-0 -- ping localhost
+```
+
+### Issue: "Import corrupted data" error
+
+**Cause**: Backup file corrupted or wrong format
+
+**Solution**:
+```bash
+# 1. Try different backup
+aws s3 ls s3://vapora-backups/database/ | sort | tail -5
+
+# 2. Verify backup format
+file vapora-db-backup.sql
+# Should show: text
+
+# 3. Manual inspection
+head -20 vapora-db-backup.sql
+# Should show SQL format
+
+# 4. Try with older backup
+```
+
+### Issue: "Database running but data seems wrong"
+
+**Cause**: Restored wrong backup or partial restore
+
+**Solution**:
+```bash
+# 1. Verify record counts
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal sql "SELECT table, count(*) FROM meta::tb"
+
+# 2. Compare to pre-loss baseline
+# (from documentation or logs)
+
+# If counts don't match:
+# - Used wrong backup
+# - Restore incomplete
+# - Try again with correct backup
+```
+
+---
+
+## Database Recovery Reference
+
+**Recovery Procedure Flowchart**:
+
+```
+Database Issue Detected
+    ↓
+Is it just a pod restart?
+  YES → kubectl delete pod surrealdb-0
+  NO → Continue
+    ↓
+Can queries connect and run?
+  YES → Continue with application recovery
+  NO → Continue
+    ↓
+Is data corrupted (errors in queries)?
+  YES → Try REBUILD INDEX
+  NO → Continue
+    ↓
+Still errors?
+  YES → Scale replicas=0, clear PVC, restore from backup
+  NO → Success, monitor for 30 min
+```

+# Disaster Recovery Runbook
+
+Step-by-step procedures for recovering VAPORA from various disaster scenarios.
+
+---
+
+## Disaster Severity Levels
+
+### Level 1: Critical 🔴
+**Complete Service Loss** - Entire VAPORA unavailable
+
+Examples:
+- Complete cluster failure
+- Complete data center outage
+- Database completely corrupted
+- All backups inaccessible
+
+RTO: 2-4 hours
+RPA: Up to 1 hour of data loss possible
+
+### Level 2: Major 🟠
+**Partial Service Loss** - Some services unavailable
+
+Examples:
+- Single region down
+- Database corrupted but backups available
+- One service completely failed
+- Primary storage unavailable
+
+RTO: 30 minutes - 2 hours
+RPA: Minimal data loss
+
+### Level 3: Minor 🟡
+**Degraded Service** - Service running but with issues
+
+Examples:
+- Performance issues
+- One pod crashed
+- Database connection issues
+- High error rate
+
+RTO: 5-15 minutes
+RPA: No data loss
+
+---
+
+## Disaster Assessment (First 5 Minutes)
+
+### Step 1: Declare Disaster State
+
+When any of these occur, declare a disaster:
+
+```bash
+# Q1: Is the service accessible?
+curl -v https://api.vapora.com/health
+
+# Q2: How many pods are running?
+kubectl get pods -n vapora
+
+# Q3: Can we access the database?
+kubectl exec -n vapora pod/<name> -- \
+  surreal query "SELECT * FROM projects LIMIT 1"
+
+# Q4: Are backups available?
+aws s3 ls s3://vapora-backups/
+```
+
+**Decision Tree**:
+```
+Can access service normally?
+  YES → No disaster, escalate to incident response
+  NO → Continue
+
+Can reach any pods?
+  YES → Partial disaster (Level 2-3)
+  NO → Likely total disaster (Level 1)
+
+Can reach database?
+  YES → Application issue, not data issue
+  NO → Database issue, need restoration
+
+Are backups accessible?
+  YES → Recovery likely possible
+  NO → Critical situation, activate backup locations
+```
+
+### Step 2: Severity Assignment
+
+Based on assessment:
+
+```bash
+# Level 1 Criteria (Critical)
+- 0 pods running in vapora namespace
+- Database completely unreachable
+- All backup locations inaccessible
+- Service down >30 minutes
+
+# Level 2 Criteria (Major)
+- <50% pods running
+- Database reachable but degraded
+- Primary backups inaccessible but secondary available
+- Service down 5-30 minutes
+
+# Level 3 Criteria (Minor)
+- >75% pods running
+- Database responsive but with errors
+- Backups accessible
+- Service down <5 minutes
+
+Assignment: Level ___
+
+If Level 1: Activate full DR plan
+If Level 2: Activate partial DR plan
+If Level 3: Use normal incident response
+```
+
+### Step 3: Notify Key Personnel
+
+```bash
+# For Level 1 (Critical) DR
+send_message_to = [
+  "@cto",
+  "@ops-manager",
+  "@database-team",
+  "@infrastructure-team",
+  "@product-manager"
+]
+
+message = """

+
+## Disaster Scenario Procedures
+
+### Scenario 1: Complete Cluster Failure
+
+**Symptoms**:
+- kubectl commands time out or fail
+- No pods running in any namespace
+- Nodes unreachable
+- All services down
+
+**Recovery Steps**:
+
+#### Step 1: Assess Infrastructure (5 min)
+
+```bash
+# Try basic cluster operations
+kubectl cluster-info
+# If: "Unable to connect to the server"
+
+# Check cloud provider status
+# AWS: Check AWS status page, check EC2 instances
+# GKE: Check Google Cloud console
+# On-prem: Check infrastructure team
+
+# Determine: Is infrastructure failed or just connectivity?
+```
+
+#### Step 2: If Infrastructure Failed
+
+**Activate Secondary Infrastructure** (if available):
+
+```bash
+# 1. Access backup/secondary infrastructure
+export KUBECONFIG=/path/to/backup/kubeconfig
+
+# 2. Verify it's operational
+kubectl cluster-info
+kubectl get nodes
+
+# 3. Prepare for database restore
+# (See: Scenario 2 - Database Recovery)
+```
+
+**If No Secondary**: Activate failover to alternate region
+
+```bash
+# 1. Contact cloud provider
+# AWS: Open support case - request emergency instance launch
+# GKE: Request cluster creation in different region
+
+# 2. While infrastructure rebuilds:
+# - Retrieve backups
+# - Prepare restore scripts
+# - Brief team on ETA
+```
+
+#### Step 3: Restore Database (See Scenario 2)
+
+#### Step 4: Deploy Services
+
+```bash
+# Once infrastructure ready and database restored
+
+# 1. Apply ConfigMaps
+kubectl apply -f vapora-configmap.yaml
+
+# 2. Apply Secrets
+kubectl apply -f vapora-secrets.yaml
+
+# 3. Deploy services
+kubectl apply -f vapora-deployments.yaml
+
+# 4. Wait for pods to start
+kubectl rollout status deployment/vapora-backend -n vapora --timeout=10m
+
+# 5. Verify health
+curl http://localhost:8001/health
+```
+
+#### Step 5: Verification
+
+```bash
+# 1. Check all pods running
+kubectl get pods -n vapora
+# All should show: Running, 1/1 Ready
+
+# 2. Verify database connectivity
+kubectl logs deployment/vapora-backend -n vapora | tail -20
+# Should show: "Successfully connected to database"
+
+# 3. Test API
+curl http://localhost:8001/api/projects
+# Should return project list
+
+# 4. Check data integrity
+# Run validation queries:
+SELECT COUNT(*) FROM projects;          # Should > 0
+SELECT COUNT(*) FROM users;             # Should > 0
+SELECT COUNT(*) FROM tasks;             # Should > 0
+```
+
+---
+
+### Scenario 2: Database Corruption/Loss
+
+**Symptoms**:
+- Database queries return errors
+- Data integrity issues
+- Corruption detected in logs
+
+**Recovery Steps**:
+
+#### Step 1: Assess Database State (10 min)
+
+```bash
+# 1. Try to connect
+kubectl exec -n vapora pod/surrealdb-0 -- \
+  surreal sql --conn ws://localhost:8000 \
+  --user root --pass "$DB_PASSWORD" \
+  "SELECT COUNT(*) FROM projects"
+
+# 2. Check for error messages
+kubectl logs -n vapora pod/surrealdb-0 | tail -50 | grep -i error
+
+# 3. Assess damage
+# Is it:
+# - Connection issue (might recover)
+# - Data corruption (need restore)
+# - Complete loss (restore from backup)
+```
+
+#### Step 2: Backup Current State (for forensics)
+
+```bash
+# Before attempting recovery, save current state
+
+# Export what's remaining
+kubectl exec -n vapora pod/surrealdb-0 -- \
+  surreal export --conn ws://localhost:8000 \
+  --user root --pass "$DB_PASSWORD" \
+  --output /tmp/corrupted-export.sql
+
+# Download for analysis
+kubectl cp vapora/surrealdb-0:/tmp/corrupted-export.sql \
+  ./corrupted-export-$(date +%Y%m%d-%H%M%S).sql
+```
+
+#### Step 3: Identify Latest Good Backup
+
+```bash
+# Find most recent backup before corruption
+aws s3 ls s3://vapora-backups/database/ --recursive | sort
+
+# Latest backup timestamp
+# Should be within last hour
+
+# Download backup
+aws s3 cp s3://vapora-backups/database/2026-01-12/vapora-db-010000.sql.gz \
+  ./vapora-db-restore.sql.gz
+
+gunzip vapora-db-restore.sql.gz
+```
+
+#### Step 4: Restore Database
+
+```bash
+# Option A: Restore to same database (destructive)
+# WARNING: This will overwrite current database
+
+kubectl exec -n vapora pod/surrealdb-0 -- \
+  rm -rf /var/lib/surrealdb/data.db
+
+# Restart pod to reinitialize
+kubectl delete pod -n vapora surrealdb-0
+# Pod will restart with clean database
+
+# Import backup
+kubectl exec -n vapora pod/surrealdb-0 -- \
+  surreal import --conn ws://localhost:8000 \
+  --user root --pass "$DB_PASSWORD" \
+  --input /tmp/vapora-db-restore.sql
+
+# Wait for import to complete (5-15 minutes)
+```
+
+**Option B: Restore to temporary database (safer)**
+
+```bash
+# 1. Create temporary database pod
+kubectl run -n vapora restore-test --image=surrealdb/surrealdb:latest \
+  -- start file:///tmp/restore-test
+
+# 2. Restore to temporary
+kubectl cp ./vapora-db-restore.sql vapora/restore-test:/tmp/
+kubectl exec -n vapora restore-test -- \
+  surreal import --conn ws://localhost:8000 \
+  --user root --pass "$DB_PASSWORD" \
+  --input /tmp/vapora-db-restore.sql
+
+# 3. Verify restored data
+kubectl exec -n vapora restore-test -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+
+# 4. If good: Restore production
+kubectl delete pod -n vapora surrealdb-0
+# Wait for pod restart
+kubectl cp ./vapora-db-restore.sql vapora/surrealdb-0:/tmp/
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal import --conn ws://localhost:8000 \
+  --user root --pass "$DB_PASSWORD" \
+  --input /tmp/vapora-db-restore.sql
+
+# 5. Cleanup test pod
+kubectl delete pod -n vapora restore-test
+```
+
+#### Step 5: Verify Recovery
+
+```bash
+# 1. Database responsive
+kubectl exec -n vapora pod/surrealdb-0 -- \
+  surreal sql "SELECT COUNT(*) FROM projects"
+
+# 2. Application can connect
+kubectl logs deployment/vapora-backend -n vapora | tail -5
+# Should show successful connection
+
+# 3. API working
+curl http://localhost:8001/api/projects
+
+# 4. Data valid
+# Check record counts match pre-backup
+# Check no corruption in key records
+```
+
+---
+
+### Scenario 3: Configuration Corruption
+
+**Symptoms**:
+- Application misconfigured
+- Pods failing to start
+- Wrong values in environment
+
+**Recovery Steps**:
+
+#### Step 1: Identify Bad Configuration
+
+```bash
+# 1. Get current ConfigMap
+kubectl get configmap -n vapora vapora-config -o yaml > current-config.yaml
+
+# 2. Compare with known-good backup
+aws s3 cp s3://vapora-backups/configs/2026-01-12/configmaps.yaml .
+
+# 3. Diff to find issues
+diff configmaps.yaml current-config.yaml
+```
+
+#### Step 2: Restore Previous Configuration
+
+```bash
+# 1. Get previous ConfigMap from backup
+aws s3 cp s3://vapora-backups/configs/2026-01-11/configmaps.yaml ./good-config.yaml
+
+# 2. Apply previous configuration
+kubectl apply -f good-config.yaml
+
+# 3. Restart pods to pick up new config
+kubectl rollout restart deployment/vapora-backend -n vapora
+kubectl rollout restart deployment/vapora-agents -n vapora
+
+# 4. Monitor restart
+kubectl get pods -n vapora -w
+```
+
+#### Step 3: Verify Configuration
+
+```bash
+# 1. Pods should restart and become Running
+kubectl get pods -n vapora
+# All should show: Running, 1/1 Ready
+
+# 2. Check pod logs
+kubectl logs deployment/vapora-backend -n vapora | tail -10
+# Should show successful startup
+
+# 3. API operational
+curl http://localhost:8001/health
+```
+
+---
+
+### Scenario 4: Data Center/Region Outage
+
+**Symptoms**:
+- Entire region unreachable
+- Multiple infrastructure components down
+- Network connectivity issues
+
+**Recovery Steps**:
+
+#### Step 1: Declare Regional Failover
+
+```bash
+# 1. Confirm region is down
+ping production.vapora.com
+# Should fail
+
+# Check status page
+# Cloud provider should report outage
+
+# 2. Declare failover
+declare_failover_to_region("us-west-2")
+```
+
+#### Step 2: Activate Alternate Region
+
+```bash
+# 1. Switch kubeconfig to alternate region
+export KUBECONFIG=/path/to/backup-region/kubeconfig
+
+# 2. Verify alternate region up
+kubectl cluster-info
+
+# 3. Download and restore database
+aws s3 cp s3://vapora-backups/database/latest/ . --recursive
+
+# 4. Restore services (as in Scenario 1, Step 4)
+```
+
+#### Step 3: Update DNS/Routing
+
+```bash
+# Update DNS to point to alternate region
+aws route53 change-resource-record-sets \
+  --hosted-zone-id Z123456 \
+  --change-batch '{
+    "Changes": [{
+      "Action": "UPSERT",
+      "ResourceRecordSet": {
+        "Name": "api.vapora.com",
+        "Type": "A",
+        "AliasTarget": {
+          "HostedZoneId": "Z987654",
+          "DNSName": "backup-region-lb.elb.amazonaws.com",
+          "EvaluateTargetHealth": false
+        }
+      }
+    }]
+  }'
+
+# Wait for DNS propagation (5-10 minutes)
+```
+
+#### Step 4: Verify Failover
+
+```bash
+# 1. DNS resolves to new region
+nslookup api.vapora.com
+
+# 2. Services accessible
+curl https://api.vapora.com/health
+
+# 3. Data intact
+curl https://api.vapora.com/api/projects
+```
+
+#### Step 5: Communicate Failover
+
+```
+Post to #incident-critical:
+
+✅ FAILOVER TO ALTERNATE REGION COMPLETE
+
+Primary Region: us-east-1 (Down)
+Active Region: us-west-2 (Restored)
+
+Status:
+- All services running: ✓
+- Database restored: ✓
+- Data integrity verified: ✓
+- Partial data loss: ~30 minutes of transactions
+
+Estimated Data Loss: 30 minutes (11:30-12:00 UTC)
+Current Time: 12:05 UTC
+
+Next steps:
+- Monitor alternate region closely
+- Begin investigation of primary region
+- Plan failback when primary recovered

+
+## Post-Disaster Recovery
+
+### Phase 1: Stabilization (Ongoing)
+
+```bash
+# Continue monitoring for 4 hours minimum
+
+# Checks every 15 minutes:
+✓ All pods Running
+✓ API responding
+✓ Database queries working
+✓ Error rates normal
+✓ Performance baseline
+```
+
+### Phase 2: Root Cause Analysis
+
+**Start within 1 hour of service recovery**:
+
+```
+Questions to answer:
+
+1. What caused the disaster?
+   - Hardware failure
+   - Software bug
+   - Configuration error
+   - External attack
+   - Human error
+
+2. Why wasn't it detected earlier?
+   - Monitoring gap
+   - Alert misconfiguration
+   - Alert fatigue
+
+3. How did backups perform?
+   - Were they accessible?
+   - Restore time as expected?
+   - Data loss acceptable?
+
+4. What took longest in recovery?
+   - Finding backups
+   - Restoring database
+   - Redeploying services
+   - Verifying integrity
+
+5. What can be improved?
+   - Faster detection
+   - Faster recovery
+   - Better documentation
+   - More automated recovery
+```
+
+### Phase 3: Recovery Documentation
+
+```
+Create post-disaster report:
+
+Timeline:
+- 11:30 UTC: Disaster detected
+- 11:35 UTC: Database restore started
+- 11:50 UTC: Services redeployed
+- 12:00 UTC: All systems operational
+- Duration: 30 minutes
+
+Impact:
+- Users affected: [X]
+- Data lost: [X] transactions
+- Revenue impact: $[X]
+
+Root cause: [Description]
+
+Contributing factors:
+1. [Factor 1]
+2. [Factor 2]
+
+Preventive measures:
+1. [Action] by [Owner] by [Date]
+2. [Action] by [Owner] by [Date]
+
+Lessons learned:
+1. [Lesson 1]
+2. [Lesson 2]
+```
+
+### Phase 4: Improvements Implementation
+
+**Due date: Within 2 weeks**
+
+```
+Checklist for improvements:
+
+□ Update backup strategy (if needed)

+  print $"Date: (date now | format date %Y-%m-%d %H:%M:%S UTC)"
+  print ""
+
+  # 1. Simulate database corruption
+  print "1. Simulating database corruption..."
+  # Create test database, introduce corruption
+
+  # 2. Test restore procedure
+  print "2. Testing restore from backup..."
+  # Download backup, restore to test database
+
+  # 3. Measure restore time
+  let start_time = (date now)
+  # ... restore process ...
+  let end_time = (date now)
+  let duration = $end_time - $start_time
+  print $"Restore time: ($duration)"
+
+  # 4. Verify data integrity
+  print "3. Verifying data integrity..."
+  # Check restored data matches pre-backup
+
+  # 5. Document results
+  print "4. Documenting results..."
+  # Record in DR drill log

+2. `02-documentation-generation` - $989/month savings
+3. `03-issue-triage` - $997/month savings
+
+**Takeaway**: VAPORA saves $2,474/month for typical usage
+
+**Time**: 40-50 minutes
+
+---
+
+## Running Examples with Parameters
+
+Some examples support command-line arguments:
+
+```bash
+# Budget enforcement with custom budget
+cargo run --example 02-budget-enforcement -p vapora-llm-router -- \
+  --monthly-budget 50000 --verbose
+
+# Learning profile with custom sample size
+cargo run --example 02-learning-profile -p vapora-agents -- \
+  --sample-size 100
+```
+
+Check example documentation for available options:
+
+```bash
+# View example header
+head -20 crates/vapora-agents/examples/02-learning-profile.rs
+```
+
+---
+
+## Troubleshooting
+
+### "example not found"
+
+Ensure you're running from workspace root:
+
+```bash
+cd /path/to/vapora
+cargo run --example 01-simple-agent -p vapora-agents
+```
+
+---
+
+### "Cannot find module"
+
+Ensure workspace is synced:
+
+```bash
+cargo update
+cargo build --examples --workspace
+```
+
+---
+
+### Example fails at runtime
+
+Check prerequisites:
+
+**Backend examples** require:
+```bash
+# Terminal 1: Start SurrealDB
+docker run -d -p 8000:8000 surrealdb/surrealdb:latest
+
+# Terminal 2: Start backend
+cd crates/vapora-backend && cargo run
+
+# Terminal 3: Run example
+cargo run --example 01-health-check -p vapora-backend
+```
+
+---
+
+### Want verbose output
+
+Set logging:
+
+```bash
+RUST_LOG=debug cargo run --example 02-learning-profile -p vapora-agents
+```
+
+---
+
+## Next Steps
+
+After exploring examples:
+
+1. **Read tutorials**: `docs/tutorials/README.md` - step-by-step guides
+2. **Study code snippets**: `docs/examples/` - quick reference
+3. **Explore source**: `crates/*/src/` - understand implementations
+4. **Run tests**: `cargo test --workspace` - verify functionality
+5. **Build projects**: Create your first VAPORA integration
+
+---
+
+## Quick Reference
+
+### Build all examples
+
+```bash
+cargo build --examples --workspace
+```
+
+### Run specific example
+
+```bash
+cargo run --example <name> -p <crate>
+```
+
+### Clean build artifacts
+
+```bash
+cargo clean
+cargo build --examples
+```
+
+### List examples in crate
+
+```bash
+ls -la crates/<crate>/examples/
+```
+
+### View example documentation
+
+```bash
+head -30 crates/<crate>/examples/<name>.rs
+```
+
+### Run with output
+
+```bash
+cargo run --example <name> -- 2>&1 | tee output.log

+<p><strong>Version</strong>: 0.1.0
+<strong>Status</strong>: Specification (VAPORA v1.0 Integration)
+<strong>Purpose</strong>: Integration of doc-lifecycle-manager as both VAPORA component AND standalone tool</p>
+<hr />
+<h2 id="-objetivo"><a class="header" href="#-objetivo">🎯 Objetivo</a></h2>
+<p><strong>doc-lifecycle-manager</strong> funciona de dos formas:</p>
+<ol>
+<li><strong>Como agente VAPORA</strong>: Documenter role usa doc-lifecycle internally</li>
+<li><strong>Como sistema standalone</strong>: Proyectos sin VAPORA usan doc-lifecycle solo</li>
+</ol>
+<p>Permite adopción gradual: empezar con doc-lifecycle solo, migrar a VAPORA después.</p>

+
+## Monitoring & Alerting
+
+### Essential Dashboards
+
+These should be visible during deployments and always on-call:
+
+1. **Kubernetes Dashboard**
+   - Pod status
+   - Node health
+   - Event logs
+
+2. **Grafana Dashboards** (if available)
+   - Request rate and latency
+   - Error rate
+   - CPU/Memory usage
+   - Pod restart counts
+
+3. **Application Logs** (Elasticsearch, CloudWatch, etc.)
+   - Error messages
+   - Stack traces
+   - Performance logs
+
+### Alert Triggers & Responses
+
+| Alert | Severity | Response |
+|-------|----------|----------|
+| Pod CrashLoopBackOff | 1 | Check logs, likely config issue |
+| Error rate >10% | 1 | Check recent deployment, consider rollback |
+| All pods pending | 1 | Node issue or resource exhausted |
+| High memory usage >90% | 2 | Check for memory leak or scale up |
+| High latency (2x normal) | 2 | Check database, external services |
+| Single pod failed | 3 | Monitor, likely transient |
+
+### Health Check Commands
+
+Quick commands to verify everything is working:
+
+```bash
+# Cluster health
+kubectl cluster-info
+kubectl get nodes        # All should be Ready
+
+# Service health
+kubectl get pods -n vapora
+# All should be Running, 1/1 Ready
+
+# Quick endpoints test
+curl http://localhost:8001/health
+curl http://localhost:3000
+
+# Pod resources
+kubectl top pods -n vapora
+
+# Recent issues
+kubectl get events -n vapora | grep Warning
+kubectl logs deployment/vapora-backend -n vapora --tail=20
+```
+
+---
+
+## Common Failure Scenarios
+
+### Pod CrashLoopBackOff
+
+**Symptoms**: Pod keeps restarting repeatedly
+
+**Diagnosis**:
+```bash
+kubectl logs <pod> -n vapora --previous  # See what crashed
+kubectl describe pod <pod> -n vapora    # Check events
+```
+
+**Solutions**:
+1. If config error: Fix ConfigMap, restart pod
+2. If code error: Rollback deployment
+3. If resource issue: Increase limits or scale out
+
+**Runbook**: [Rollback Runbook](./rollback-runbook.md) or [Incident Response](./incident-response-runbook.md)
+
+### Pod Stuck in Pending
+
+**Symptoms**: Pod won't start, stuck in "Pending" state
+
+**Diagnosis**:
+```bash
+kubectl describe pod <pod> -n vapora  # Check "Events" section
+```
+
+**Common causes**:
+- Insufficient CPU/memory on nodes
+- Node disk full
+- Pod can't be scheduled
+- Persistent volume not available
+
+**Solutions**:
+1. Scale down other workloads
+2. Add more nodes
+3. Fix persistent volume issues
+4. Check node disk space
+
+**Runbook**: [On-Call Procedures](./on-call-procedures.md) → "Common Questions"
+
+### Service Unresponsive (Connection Refused)
+
+**Symptoms**: `curl: (7) Failed to connect to localhost port 8001`
+
+**Diagnosis**:
+```bash
+kubectl get pods -n vapora      # Are pods even running?
+kubectl get service vapora-backend -n vapora  # Does service exist?
+kubectl get endpoints -n vapora # Do endpoints exist?
+```
+
+**Common causes**:
+- Pods not running (restart loops)
+- Service missing or misconfigured
+- Port incorrect
+- Network policy blocking traffic
+
+**Solutions**:
+1. Verify pods running: `kubectl get pods`
+2. Verify service exists: `kubectl get svc`
+3. Check endpoints: `kubectl get endpoints`
+4. Port-forward if issue with routing: `kubectl port-forward svc/vapora-backend 8001:8001`
+
+**Runbook**: [Incident Response](./incident-response-runbook.md)
+
+### High Error Rate
+
+**Symptoms**: Dashboard shows >5% 5xx errors
+
+**Diagnosis**:
+```bash
+# Check which endpoint
+kubectl logs deployment/vapora-backend -n vapora | grep "ERROR\|500"
+
+# Check recent deployment
+git log -1 --oneline provisioning/
+
+# Check dependencies
+curl http://localhost:8001/health  # is it healthy?
+```
+
+**Common causes**:
+- Recent bad deployment
+- Database connectivity issue
+- Configuration error
+- Dependency service down
+
+**Solutions**:
+1. If recent deployment: Consider rollback
+2. Check ConfigMap for typos
+3. Check database connectivity
+4. Check external service health
+
+**Runbook**: [Rollback Runbook](./rollback-runbook.md) or [Incident Response](./incident-response-runbook.md)
+
+### Resource Exhaustion (CPU/Memory)
+
+**Symptoms**: `kubectl top pods` shows pod at 100% usage or "limits exceeded"
+
+**Diagnosis**:
+```bash
+kubectl top nodes              # Overall node usage
+kubectl top pods -n vapora     # Per-pod usage
+kubectl get pod <pod> -o yaml | grep limits -A 10  # Check limits
+```
+
+**Solutions**:
+1. Increase pod resource limits (requires redeployment)
+2. Scale out (add more replicas)
+3. Scale down other workloads
+4. Investigate memory leak if growing
+
+**Runbook**: [Deployment Runbook](./deployment-runbook.md) → Phase 4 (Verification)
+
+### Database Connection Errors
+
+**Symptoms**: `ERROR: could not connect to database`
+
+**Diagnosis**:
+```bash
+# Check database is running
+kubectl get pods -n <database-namespace>
+
+# Check credentials in ConfigMap
+kubectl get configmap vapora-config -n vapora -o yaml | grep -i "database\|password"
+
+# Test connectivity
+kubectl exec <pod> -n vapora -- psql $DATABASE_URL
+```
+
+**Solutions**:
+1. If credentials wrong: Fix in ConfigMap, restart pods
+2. If database down: Escalate to DBA
+3. If network issue: Network team investigation
+4. If permissions: Update database user
+
+**Runbook**: [Incident Response](./incident-response-runbook.md) → "Root Cause: Database Issues"

+<p>Automated backup and recovery procedures using Nushell scripts and Kubernetes CronJobs. Supports both direct S3 backups and Restic-based incremental backups.</p>
+<hr />
+<h2 id="overview"><a class="header" href="#overview">Overview</a></h2>
+<p><strong>Backup Strategy</strong>:</p>
+<ul>
+<li>Hourly: Database export + Restic backup (1-hour RPO)</li>
+<li>Daily: Kubernetes config backup + Restic backup</li>
+<li>Monthly: Cleanup old snapshots and archive</li>
+</ul>
+<p><strong>Dual Backup Approach</strong>:</p>
+<ul>
+<li><strong>S3 Direct</strong>: Simple file upload for quick recovery</li>
+<li><strong>Restic</strong>: Incremental, deduplicated backups with integrated encryption</li>
+</ul>
+<p><strong>Recovery Procedures</strong>:</p>
+<ul>
+<li>One-command restore from S3 or Restic</li>
+<li>Verification before committing to production</li>
+<li>Automated database readiness checks</li>

+# VAPORA Automated Backup & Recovery Automation
+
+Automated backup and recovery procedures using Nushell scripts and Kubernetes CronJobs. Supports both direct S3 backups and Restic-based incremental backups.
+
+---
+
+## Overview
+
+**Backup Strategy**:
+- Hourly: Database export + Restic backup (1-hour RPO)
+- Daily: Kubernetes config backup + Restic backup
+- Monthly: Cleanup old snapshots and archive
+
+**Dual Backup Approach**:
+- **S3 Direct**: Simple file upload for quick recovery
+- **Restic**: Incremental, deduplicated backups with integrated encryption
+
+**Recovery Procedures**:
+- One-command restore from S3 or Restic
+- Verification before committing to production
+- Automated database readiness checks
+
+---
+
+## Files and Components
+
+### Backup Scripts
+
+All scripts follow NUSHELL_GUIDELINES.md (0.109.0+) strictly.
+
+#### `scripts/backup/database-backup.nu`
+
+Direct S3 backup of SurrealDB with encryption.
+
+```bash
+nu scripts/backup/database-backup.nu \
+  --surreal-url "ws://localhost:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS" \
+  --s3-bucket "vapora-backups" \
+  --s3-prefix "backups/database" \
+  --encryption-key "$ENCRYPTION_KEY_FILE"
+```
+
+**Process**:
+1. Export SurrealDB to SQL
+2. Compress with gzip
+3. Encrypt with AES-256
+4. Upload to S3 with metadata
+5. Verify upload completed
+
+**Output**: `s3://vapora-backups/backups/database/database-YYYYMMDD-HHMMSS.sql.gz.enc`
+
+#### `scripts/backup/config-backup.nu`
+
+Backup Kubernetes resources (ConfigMaps, Secrets, Deployments).
+
+```bash
+nu scripts/backup/config-backup.nu \
+  --namespace "vapora" \
+  --s3-bucket "vapora-backups" \
+  --s3-prefix "backups/config"
+```
+
+**Process**:
+1. Export ConfigMaps from namespace
+2. Export Secrets
+3. Export Deployments, Services, Ingress
+4. Compress all to tar.gz
+5. Upload to S3
+
+**Output**: `s3://vapora-backups/backups/config/configs-YYYYMMDD-HHMMSS.tar.gz`
+
+#### `scripts/backup/restic-backup.nu`
+
+Incremental, deduplicated backup using Restic.
+
+```bash
+nu scripts/backup/restic-backup.nu \
+  --repo "s3:s3.amazonaws.com/vapora-backups/restic" \
+  --password "$RESTIC_PASSWORD" \
+  --database-dir "/tmp/vapora-db-backup" \
+  --k8s-dir "/tmp/vapora-k8s-backup" \
+  --iac-dir "provisioning" \
+  --backup-db \
+  --backup-k8s \
+  --backup-iac \
+  --verify \
+  --cleanup \
+  --keep-daily 7 \
+  --keep-weekly 4 \
+  --keep-monthly 12
+```
+
+**Features**:
+- Incremental backups (only changed data stored)
+- Deduplication across snapshots
+- Built-in compression and encryption
+- Automatic retention policies
+- Repository health verification
+
+**Output**: Tagged snapshots in Restic repository with metadata
+
+#### `scripts/orchestrate-backup-recovery.nu`
+
+Coordinates all backup types (S3 + Restic).
+
+```bash
+# Full backup cycle
+nu scripts/orchestrate-backup-recovery.nu \
+  --operation backup \
+  --mode full \
+  --surreal-url "ws://localhost:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS" \
+  --namespace "vapora" \
+  --s3-bucket "vapora-backups" \
+  --s3-prefix "backups/database" \
+  --encryption-key "$ENCRYPTION_KEY_FILE" \
+  --restic-repo "s3:s3.amazonaws.com/vapora-backups/restic" \
+  --restic-password "$RESTIC_PASSWORD" \
+  --iac-dir "provisioning"
+```
+
+**Modes**:
+- `full`: Database export → S3 + Restic
+- `database-only`: Database export only
+- `config-only`: Kubernetes config only
+
+### Recovery Scripts
+
+#### `scripts/recovery/database-recovery.nu`
+
+Restore SurrealDB from S3 backup (with decryption).
+
+```bash
+nu scripts/recovery/database-recovery.nu \
+  --s3-location "s3://vapora-backups/backups/database/database-20260112-010000.sql.gz.enc" \
+  --encryption-key "$ENCRYPTION_KEY_FILE" \
+  --surreal-url "ws://localhost:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS" \
+  --namespace "vapora" \
+  --statefulset "surrealdb" \
+  --pvc "surrealdb-data-surrealdb-0" \
+  --verify
+```
+
+**Process**:
+1. Download encrypted backup from S3
+2. Decrypt backup file
+3. Decompress backup
+4. Scale down StatefulSet (for PVC replacement)
+5. Delete current PVC
+6. Scale up StatefulSet (creates new PVC)
+7. Wait for pod readiness
+8. Import backup to database
+9. Verify data integrity
+
+**Output**: Restored database at specified SurrealDB URL
+
+#### `scripts/orchestrate-backup-recovery.nu` (Recovery Mode)
+
+One-command recovery from backup.
+
+```bash
+nu scripts/orchestrate-backup-recovery.nu \
+  --operation recovery \
+  --s3-location "s3://vapora-backups/backups/database/database-20260112-010000.sql.gz.enc" \
+  --encryption-key "$ENCRYPTION_KEY_FILE" \
+  --surreal-url "ws://localhost:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS"
+```
+
+### Verification Scripts
+
+#### `scripts/verify-backup-health.nu`
+
+Health check for backup infrastructure.
+
+```bash
+# Basic health check
+nu scripts/verify-backup-health.nu \
+  --s3-bucket "vapora-backups" \
+  --s3-prefix "backups/database" \
+  --restic-repo "s3:s3.amazonaws.com/vapora-backups/restic" \
+  --restic-password "$RESTIC_PASSWORD" \
+  --surreal-url "ws://localhost:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS" \
+  --max-age-hours 25
+```
+
+**Checks Performed**:
+- ✓ S3 backups exist and have content
+- ✓ Restic repository accessible and has snapshots
+- ✓ Database connectivity verified
+- ✓ Backup freshness (< 25 hours old)
+- ✓ Backup rotation policy (daily, weekly, monthly)
+- ✓ Restore test (if `--full-test` specified)
+
+**Output**: Pass/fail for each check with detailed status
+

+
+## Kubernetes Automation
+
+### CronJob Configuration
+
+File: `kubernetes/09-backup-cronjobs.yaml`
+
+Defines four automated CronJobs:
+
+#### 1. Hourly Database Backup
+
+```yaml
+schedule: "0 * * * *"  # Every hour
+timeout: 1800 seconds  # 30 minutes
+```
+
+Runs `orchestrate-backup-recovery.nu --operation backup --mode full`
+
+**Backups**:
+- SurrealDB to S3 (encrypted)
+- SurrealDB to Restic (incremental)
+- IaC to Restic
+
+#### 2. Daily Configuration Backup
+
+```yaml
+schedule: "0 2 * * *"  # 02:00 UTC daily
+timeout: 3600 seconds  # 60 minutes
+```
+
+Runs `config-backup.nu` for Kubernetes resources.
+
+#### 3. Daily Health Verification
+
+```yaml
+schedule: "0 3 * * *"  # 03:00 UTC daily
+timeout: 900 seconds   # 15 minutes
+```
+
+Runs `verify-backup-health.nu` to verify backup infrastructure.
+
+**Alerts if**:
+- No S3 backups found
+- Restic repository inaccessible
+- Database unreachable
+- Backups older than 25 hours
+- Rotation policy violated
+
+#### 4. Monthly Backup Rotation
+
+```yaml
+schedule: "0 4 1 * *"  # First day of month, 04:00 UTC
+timeout: 3600 seconds
+```
+
+Cleans up old Restic snapshots per retention policy:
+- Keep: 7 daily, 4 weekly, 12 monthly
+- Prune: Remove unreferenced data
+
+### Environment Configuration
+
+CronJobs require these secrets and ConfigMaps:
+
+**ConfigMap: `vapora-config`**
+
+```yaml
+backup_s3_bucket: "vapora-backups"
+restic_repo: "s3:s3.amazonaws.com/vapora-backups/restic"
+aws_region: "us-east-1"
+```
+
+**Secret: `vapora-secrets`**
+
+```yaml
+surreal_password: "<database-password>"
+restic_password: "<restic-encryption-password>"
+```
+
+**Secret: `vapora-aws-credentials`**
+
+```yaml
+access_key_id: "<aws-access-key>"
+secret_access_key: "<aws-secret-key>"
+```
+
+**Secret: `vapora-encryption-key`**
+
+```yaml
+# File containing AES-256 encryption key
+encryption.key: "<binary-key-data>"
+```
+
+### Deployment
+
+1. **Create secrets** (if not existing):
+
+```bash
+kubectl create secret generic vapora-secrets \
+  --from-literal=surreal_password="$SURREAL_PASS" \
+  --from-literal=restic_password="$RESTIC_PASSWORD" \
+  -n vapora
+
+kubectl create secret generic vapora-aws-credentials \
+  --from-literal=access_key_id="$AWS_ACCESS_KEY_ID" \
+  --from-literal=secret_access_key="$AWS_SECRET_ACCESS_KEY" \
+  -n vapora
+
+kubectl create secret generic vapora-encryption-key \
+  --from-file=encryption.key=/path/to/encryption.key \
+  -n vapora
+```
+
+2. **Deploy CronJobs**:
+
+```bash
+kubectl apply -f kubernetes/09-backup-cronjobs.yaml
+```
+
+3. **Verify CronJobs**:
+
+```bash
+kubectl get cronjobs -n vapora
+kubectl describe cronjob vapora-backup-database-hourly -n vapora
+```
+
+4. **Monitor scheduled runs**:
+
+```bash
+# Watch CronJob executions
+kubectl get jobs -n vapora -l job-type=backup --watch
+
+# View logs from backup job
+kubectl logs -n vapora -l backup-type=database --tail=100 -f
+```
+
+---
+
+## Setup Instructions
+
+### Prerequisites
+
+- Kubernetes 1.18+ with CronJob support
+- Nushell 0.109.0+
+- AWS CLI v2+
+- Restic installed (or container image with restic)
+- SurrealDB CLI (`surreal` command)
+- `kubectl` with cluster access
+
+### Local Testing
+
+1. **Setup environment variables**:
+
+```bash
+export SURREAL_URL="ws://localhost:8000"
+export SURREAL_USER="root"
+export SURREAL_PASS="password"
+export S3_BUCKET="vapora-backups"
+export ENCRYPTION_KEY_FILE="/path/to/encryption.key"
+export RESTIC_REPO="s3:s3.amazonaws.com/vapora-backups/restic"
+export RESTIC_PASSWORD="restic-password"
+export AWS_REGION="us-east-1"
+export AWS_ACCESS_KEY_ID="your-key"
+export AWS_SECRET_ACCESS_KEY="your-secret"
+```
+
+2. **Run backup**:
+
+```bash
+nu scripts/orchestrate-backup-recovery.nu \
+  --operation backup \
+  --mode full \
+  --surreal-url "$SURREAL_URL" \
+  --surreal-user "$SURREAL_USER" \
+  --surreal-pass "$SURREAL_PASS" \
+  --s3-bucket "$S3_BUCKET" \
+  --s3-prefix "backups/database" \
+  --encryption-key "$ENCRYPTION_KEY_FILE" \
+  --restic-repo "$RESTIC_REPO" \
+  --restic-password "$RESTIC_PASSWORD" \
+  --iac-dir "provisioning"
+```
+
+3. **Verify backup**:
+
+```bash
+nu scripts/verify-backup-health.nu \
+  --s3-bucket "$S3_BUCKET" \
+  --s3-prefix "backups/database" \
+  --restic-repo "$RESTIC_REPO" \
+  --restic-password "$RESTIC_PASSWORD" \
+  --surreal-url "$SURREAL_URL" \
+  --surreal-user "$SURREAL_USER" \
+  --surreal-pass "$SURREAL_PASS"
+```
+
+4. **Test recovery**:
+
+```bash
+# First, list available backups
+aws s3 ls s3://$S3_BUCKET/backups/database/
+
+# Then recover from latest backup
+nu scripts/orchestrate-backup-recovery.nu \
+  --operation recovery \
+  --s3-location "s3://$S3_BUCKET/backups/database/database-20260112-010000.sql.gz.enc" \
+  --encryption-key "$ENCRYPTION_KEY_FILE" \
+  --surreal-url "$SURREAL_URL" \
+  --surreal-user "$SURREAL_USER" \
+  --surreal-pass "$SURREAL_PASS"
+```
+
+### Production Deployment
+
+1. **Create S3 bucket** for backups:
+
+```bash
+aws s3 mb s3://vapora-backups --region us-east-1
+```
+
+2. **Enable bucket versioning** for protection:
+
+```bash
+aws s3api put-bucket-versioning \
+  --bucket vapora-backups \
+  --versioning-configuration Status=Enabled
+```
+
+3. **Set lifecycle policy** for Glacier archival (optional):
+
+```bash
+# 30 days to standard-IA, 90 days to Glacier
+aws s3api put-bucket-lifecycle-configuration \
+  --bucket vapora-backups \
+  --lifecycle-configuration file://s3-lifecycle-policy.json
+```
+
+4. **Create Restic repository**:
+
+```bash
+export RESTIC_REPO="s3:s3.amazonaws.com/vapora-backups/restic"
+export RESTIC_PASSWORD="your-restic-password"
+
+restic init
+```
+
+5. **Deploy to Kubernetes**:
+
+```bash
+# 1. Create namespace
+kubectl create namespace vapora
+
+# 2. Create secrets
+kubectl create secret generic vapora-secrets \
+  --from-literal=surreal_password="$SURREAL_PASS" \
+  --from-literal=restic_password="$RESTIC_PASSWORD" \
+  -n vapora
+
+# 3. Create ConfigMap
+kubectl create configmap vapora-config \
+  --from-literal=backup_s3_bucket="vapora-backups" \
+  --from-literal=restic_repo="s3:s3.amazonaws.com/vapora-backups/restic" \
+  --from-literal=aws_region="us-east-1" \
+  -n vapora
+
+# 4. Deploy CronJobs
+kubectl apply -f kubernetes/09-backup-cronjobs.yaml
+```
+
+6. **Monitor**:
+
+```bash
+# Watch CronJobs
+kubectl get cronjobs -n vapora --watch
+
+# View backup logs
+kubectl logs -n vapora -l backup-type=database -f
+
+# Check health status
+kubectl get jobs -n vapora -l job-type=health-check -o wide
+```
+
+---
+
+## Emergency Recovery
+
+### Complete Database Loss
+
+If production database is lost, restore from backup:
+
+```bash
+# 1. Scale down StatefulSet
+kubectl scale statefulset surrealdb --replicas=0 -n vapora
+
+# 2. Delete current PVC
+kubectl delete pvc surrealdb-data-surrealdb-0 -n vapora
+
+# 3. Run recovery
+nu scripts/orchestrate-backup-recovery.nu \
+  --operation recovery \
+  --s3-location "s3://vapora-backups/backups/database/database-LATEST.sql.gz.enc" \
+  --encryption-key "/path/to/encryption.key" \
+  --surreal-url "ws://surrealdb:8000" \
+  --surreal-user "root" \
+  --surreal-pass "$SURREAL_PASS"
+
+# 4. Verify database restored
+kubectl exec -n vapora surrealdb-0 -- \
+  surreal query \
+    --conn ws://localhost:8000 \
+    --user root \
+    --pass "$SURREAL_PASS" \
+    "SELECT COUNT() FROM projects"
+```
+
+### Backup Verification Failed
+
+If health check fails:
+
+1. **Check Restic repository**:
+
+```bash
+export RESTIC_PASSWORD="$RESTIC_PASSWORD"
+restic -r "s3:s3.amazonaws.com/vapora-backups/restic" check
+```
+
+2. **Force full verification** (slow):
+
+```bash
+restic -r "s3:s3.amazonaws.com/vapora-backups/restic" check --read-data
+```
+
+3. **List recent snapshots**:
+
+```bash
+restic -r "s3:s3.amazonaws.com/vapora-backups/restic" snapshots --max 10
+```
+
+---
+
+## Troubleshooting
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| **CronJob not running** | Schedule incorrect | Check `kubectl get cronjobs` and verify schedule format |
+| **Backup file too large** | Database growing | Check for old data that can be cleaned up |
+| **S3 upload fails** | Credentials invalid | Verify `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY` |
+| **Restic backup slow** | First backup or network latency | Expected on first run; use `--keep-*` flags to limit retention |
+| **Recovery fails** | Database already running | Scale down StatefulSet before recovery |
+| **Encryption key missing** | Secret not created | Create `vapora-encryption-key` secret in namespace |

+# Deployment Runbook
+
+Step-by-step procedures for deploying VAPORA to staging and production environments.
+
+---
+
+## Quick Start
+
+For experienced operators:
+
+```bash
+# Validate in CI/CD
+# Download artifacts
+# Review dry-run
+# Apply: kubectl apply -f configmap.yaml deployment.yaml
+# Monitor: kubectl logs -f deployment/vapora-backend -n vapora
+# Verify: curl http://localhost:8001/health
+```
+
+For complete steps, continue reading.
+
+---
+
+## Before Starting
+
+✅ **Prerequisites Completed**:
+- [ ] Pre-deployment checklist completed
+- [ ] Artifacts generated and validated
+- [ ] Staging deployment verified
+- [ ] Team ready and monitoring
+- [ ] Maintenance window announced
+
+✅ **Access Verified**:
+- [ ] kubectl configured for target cluster
+- [ ] Can list nodes: `kubectl get nodes`
+- [ ] Can access namespace: `kubectl get namespace vapora`
+
+❌ **If any prerequisite missing**: Go back to pre-deployment checklist
+
+---
+
+## Phase 1: Pre-Flight (5 minutes)
+
+### 1.1 Verify Current State
+
+```bash
+# Set context
+export CLUSTER=production  # or staging
+export NAMESPACE=vapora
+
+# Verify cluster access
+kubectl cluster-info
+kubectl get nodes
+
+# Output should show:
+# NAME     STATUS   ROLES    AGE
+# node-1   Ready    worker   30d
+# node-2   Ready    worker   25d
+```
+
+**What to look for:**
+- ✓ All nodes in "Ready" state
+- ✓ No "NotReady" or "Unknown" nodes
+- If issues: Don't proceed, investigate node health
+
+### 1.2 Check Current Deployments
+
+```bash
+# Get current deployment status
+kubectl get deployments -n $NAMESPACE -o wide
+kubectl get pods -n $NAMESPACE
+
+# Output example:
+# NAME                READY   UP-TO-DATE   AVAILABLE
+# vapora-backend      3/3     3            3
+# vapora-agents       2/2     2            2
+# vapora-llm-router   2/2     2            2
+```
+
+**What to look for:**
+- ✓ All deployments showing correct replica count
+- ✓ All pods in "Running" state
+- ❌ If pods in "CrashLoopBackOff" or "Pending": Investigate before proceeding
+
+### 1.3 Record Current Versions
+
+```bash
+# Get current image versions (baseline for rollback)
+kubectl get deployments -n $NAMESPACE -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.template.spec.containers[0].image}{"\n"}{end}'
+
+# Expected output:
+# vapora-backend      vapora/backend:v1.2.0
+# vapora-agents       vapora/agents:v1.2.0
+# vapora-llm-router   vapora/llm-router:v1.2.0
+```
+
+**Record these for rollback**: Keep this output visible
+
+### 1.4 Get Current Revision Numbers
+
+```bash
+# For each deployment, get rollout history
+for deployment in vapora-backend vapora-agents vapora-llm-router; do
+  echo "=== $deployment ==="
+  kubectl rollout history deployment/$deployment -n $NAMESPACE | tail -5
+done
+
+# Output example:
+# REVISION  CHANGE-CAUSE
+# 42        Deployment rolled out
+# 43        Deployment rolled out
+# 44        (current)
+```
+
+**Record the highest revision number for each** - this is your rollback reference
+
+### 1.5 Check Cluster Resources
+
+```bash
+# Verify cluster has capacity for new deployment
+kubectl top nodes
+kubectl describe nodes | grep -A 5 "Allocated resources"
+
+# Example - check memory/CPU availability
+# Requested:     8200m (41%)
+# Limits:        16400m (82%)
+```
+
+**What to look for:**
+- ✓ Less than 80% resource utilization
+- ❌ If above 85%: Insufficient capacity, don't proceed
+
+---
+
+## Phase 2: Configuration Deployment (3 minutes)
+
+### 2.1 Apply ConfigMap
+
+The ConfigMap contains all application configuration.
+
+```bash
+# First: Dry-run to verify no syntax errors
+kubectl apply -f configmap.yaml --dry-run=server -n $NAMESPACE
+
+# Should output:
+# configmap/vapora-config configured (server dry run)
+
+# Check for any warnings or errors in output
+# If errors, stop and fix the YAML before proceeding
+```
+
+**Troubleshooting**:
+- "error validating": YAML syntax error - fix and retry
+- "field is immutable": Can't change certain ConfigMap fields - delete and recreate
+- "resourceQuotaExceeded": Namespace quota exceeded - contact cluster admin
+
+### 2.2 Apply ConfigMap for Real
+
+```bash
+# Apply the actual ConfigMap
+kubectl apply -f configmap.yaml -n $NAMESPACE
+
+# Output:
+# configmap/vapora-config configured
+
+# Verify it was applied
+kubectl get configmap -n $NAMESPACE vapora-config -o yaml | head -20
+
+# Check for your new values in the output
+```
+
+**Verify ConfigMap is correct**:
+```bash
+# Extract specific values to verify
+kubectl get configmap vapora-config -n $NAMESPACE -o jsonpath='{.data.vapora\.toml}' | grep "database_url" | head -1
+
+# Should show the correct database URL
+```
+
+### 2.3 Annotate ConfigMap
+
+Record when this config was deployed for audit trail:
+
+```bash
+kubectl annotate configmap vapora-config \
+  -n $NAMESPACE \
+  deployment.timestamp="$(date -u +'%Y-%m-%dT%H:%M:%SZ')" \
+  deployment.commit="$(git rev-parse HEAD | cut -c1-8)" \
+  deployment.branch="$(git rev-parse --abbrev-ref HEAD)" \
+  --overwrite
+
+# Verify annotation was added
+kubectl get configmap vapora-config -n $NAMESPACE -o yaml | grep "deployment\."
+```
+
+---
+
+## Phase 3: Deployment Update (5 minutes)
+
+### 3.1 Dry-Run Deployment
+
+Always dry-run first to catch issues:
+
+```bash
+# Run deployment dry-run
+kubectl apply -f deployment.yaml --dry-run=server -n $NAMESPACE
+
+# Output should show what will be updated:
+# deployment.apps/vapora-backend configured (server dry run)
+# deployment.apps/vapora-agents configured (server dry run)
+# deployment.apps/vapora-llm-router configured (server dry run)
+```
+
+**Check for warnings**:
+- "imagePullBackOff": Docker image doesn't exist
+- "insufficient quota": Resource limits exceeded
+- "nodeAffinity": Pod can't be placed on any node
+
+### 3.2 Apply Deployments
+
+```bash
+# Apply the actual deployments
+kubectl apply -f deployment.yaml -n $NAMESPACE
+
+# Output:
+# deployment.apps/vapora-backend configured
+# deployment.apps/vapora-agents configured
+# deployment.apps/vapora-llm-router configured
+```
+
+**Verify deployments updated**:
+```bash
+# Check that new rollout was initiated
+kubectl get deployments -n $NAMESPACE -o jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.status.observedGeneration}{"\n"}{end}'
+
+# Compare with recorded versions - should be incremented
+```
+
+### 3.3 Monitor Rollout Progress
+
+Watch the deployment rollout status:
+
+```bash
+# For each deployment, monitor the rollout
+for deployment in vapora-backend vapora-agents vapora-llm-router; do
+  echo "Waiting for $deployment..."
+  kubectl rollout status deployment/$deployment \
+    -n $NAMESPACE \
+    --timeout=5m
+  echo "$deployment ready"
+done
+```
+
+**What to look for** (per pod update):
+```
+Waiting for rollout to finish: 2 of 3 updated replicas are available...
+Waiting for rollout to finish: 2 of 3 updated replicas are available...
+Waiting for rollout to finish: 3 of 3 updated replicas are available...
+deployment "vapora-backend" successfully rolled out
+```
+
+**Expected time: 2-3 minutes per deployment**
+
+### 3.4 Watch Pod Updates (in separate terminal)
+
+While rollout completes, monitor pods:
+
+```bash
+# Watch pods being updated in real-time
+kubectl get pods -n $NAMESPACE -w
+
+# Output shows updates like:
+# NAME                              READY   STATUS
+# vapora-backend-abc123-def45       1/1     Running
+# vapora-backend-xyz789-old-pod     1/1     Running  ← old pod still running
+# vapora-backend-abc123-new-pod     0/1     Pending  ← new pod starting
+# vapora-backend-abc123-new-pod     0/1     ContainerCreating
+# vapora-backend-abc123-new-pod     1/1     Running  ← new pod ready
+# vapora-backend-xyz789-old-pod     1/1     Terminating  ← old pod being removed
+```
+
+**What to look for:**
+- ✓ New pods starting (Pending → ContainerCreating → Running)
+- ✓ Each new pod reaches Running state
+- ✓ Old pods gradually terminating
+- ❌ Pod stuck in "CrashLoopBackOff": Stop, check logs, might need rollback
+
+---
+
+## Phase 4: Verification (5 minutes)
+
+### 4.1 Verify All Pods Running
+
+```bash
+# Check all pods are ready
+kubectl get pods -n $NAMESPACE
+
+# Expected output:
+# NAME                              READY   STATUS
+# vapora-backend-<hash>-1           1/1     Running
+# vapora-backend-<hash>-2           1/1     Running
+# vapora-backend-<hash>-3           1/1     Running
+# vapora-agents-<hash>-1            1/1     Running
+# vapora-agents-<hash>-2            1/1     Running
+# vapora-llm-router-<hash>-1        1/1     Running
+# vapora-llm-router-<hash>-2        1/1     Running
+```
+
+**Verification**:
+```bash
+# All pods should show READY=1/1
+# All pods should show STATUS=Running
+# No pods should be in Pending, CrashLoopBackOff, or Error state
+
+# Quick check:
+READY=$(kubectl get pods -n $NAMESPACE -o jsonpath='{range .items[*]}{.status.conditions[?(@.type=="Ready")].status}{"\n"}{end}' | grep -c "True")
+TOTAL=$(kubectl get pods -n $NAMESPACE --no-headers | wc -l)
+
+echo "Ready pods: $READY / $TOTAL"
+
+# Should show: Ready pods: 7 / 7 (or your expected pod count)
+```
+
+### 4.2 Check Pod Logs for Errors
+
+```bash
+# Check logs from the last minute for errors
+for pod in $(kubectl get pods -n $NAMESPACE -o name); do
+  echo "=== $pod ==="
+  kubectl logs $pod -n $NAMESPACE --since=1m 2>&1 | grep -i "error\|exception\|fatal" | head -3
+done
+
+# If errors found:
+# 1. Note which pods have errors
+# 2. Get full log: kubectl logs <pod> -n $NAMESPACE
+# 3. Decide: can proceed or need to rollback
+```
+
+### 4.3 Verify Service Endpoints
+
+```bash
+# Check services are exposing pods correctly
+kubectl get endpoints -n $NAMESPACE
+
+# Expected output:
+# NAME              ENDPOINTS
+# vapora-backend    10.1.2.3:8001,10.1.2.4:8001,10.1.2.5:8001
+# vapora-agents     10.1.2.6:8002,10.1.2.7:8002
+# vapora-llm-router 10.1.2.8:8003,10.1.2.9:8003
+```
+
+**Verification**:
+- ✓ Each service has multiple endpoints (not empty)
+- ✓ Endpoints match running pods
+- ❌ If empty endpoints: Service can't route traffic
+
+### 4.4 Health Check Endpoints
+
+```bash
+# Port-forward to access services locally
+kubectl port-forward -n $NAMESPACE svc/vapora-backend 8001:8001 &
+
+# Wait a moment for port-forward to establish
+sleep 2
+
+# Check backend health
+curl -v http://localhost:8001/health
+
+# Expected response:
+# HTTP/1.1 200 OK
+# {...healthy response...}
+
+# Check other endpoints
+curl http://localhost:8001/api/projects -H "Authorization: Bearer test-token"
+```
+
+**Expected responses**:
+- `/health`: 200 OK with health data
+- `/api/projects`: 200 OK with projects list
+- `/metrics`: 200 OK with Prometheus metrics
+
+**If connection refused**:
+```bash
+# Check if port-forward working
+ps aux | grep "port-forward"
+
+# Restart port-forward
+pkill -f "port-forward svc/vapora-backend"
+kubectl port-forward -n $NAMESPACE svc/vapora-backend 8001:8001 &
+```
+
+### 4.5 Check Metrics
+
+```bash
+# Monitor resource usage of deployed pods
+kubectl top pods -n $NAMESPACE
+
+# Expected output:
+# NAME                           CPU(cores)   MEMORY(Mi)
+# vapora-backend-abc123          250m         512Mi
+# vapora-backend-def456          280m         498Mi
+# vapora-agents-ghi789           300m         256Mi
+```
+
+**Verification**:
+- ✓ CPU usage within expected range (typically 100-500m per pod)
+- ✓ Memory usage within expected range (typically 200-512Mi)
+- ❌ If any pod at 100% CPU/Memory: Performance issue, monitor closely
+
+---
+
+## Phase 5: Validation (3 minutes)
+
+### 5.1 Run Smoke Tests (if available)
+
+```bash
+# If your project has smoke tests:
+kubectl exec -it deployment/vapora-backend -n $NAMESPACE -- \
+  sh -c "curl http://localhost:8001/health && echo 'Health check passed'"
+
+# Or run from your local machine:
+./scripts/smoke-tests.sh --endpoint http://localhost:8001
+```
+
+### 5.2 Check for Errors in Logs
+
+```bash
+# Look at logs from all pods since deployment started
+for deployment in vapora-backend vapora-agents vapora-llm-router; do
+  echo "=== Checking $deployment ==="
+  kubectl logs deployment/$deployment -n $NAMESPACE --since=5m 2>&1 | \
+    grep -i "error\|exception\|failed" | wc -l
+done
+
+# If any errors found:
+# 1. Get detailed logs
+# 2. Determine if critical or expected errors
+# 3. Decide to proceed or rollback
+```
+
+### 5.3 Compare Against Baseline Metrics
+
+Compare current metrics with pre-deployment baseline:
+
+```bash
+# Current metrics
+echo "=== Current ==="
+kubectl top nodes
+kubectl top pods -n $NAMESPACE | head -5
+
+# Compare with recorded baseline
+# If similar: ✓ Good
+# If significantly higher: ⚠️ Watch for issues
+# If error rates high: ❌ Consider rollback
+```
+
+### 5.4 Check for Recent Events/Warnings
+
+```bash
+# Look for any cluster events in the last 5 minutes
+kubectl get events -n $NAMESPACE --sort-by='.lastTimestamp' | tail -20
+
+# Watch for:
+# - Warning: FailedScheduling (pod won't fit)
+# - Warning: PullImageError (image doesn't exist)
+# - Warning: ImagePullBackOff (can't download image)
+# - Error: ExceededQuota (resource limits)
+```
+

+- [ ] Post in #product: "Backend updated to v1.2.1, new features available"
+- [ ] Update ticket/issue with deployment completion time and status
+
+---
+
+## Phase 7: Post-Deployment Monitoring (Ongoing)
+
+### 7.1 First 5 Minutes: Watch Closely
+
+```bash
+# Keep watching for any issues
+watch kubectl get pods -n $NAMESPACE
+watch kubectl top pods -n $NAMESPACE
+watch kubectl logs -f deployment/vapora-backend -n $NAMESPACE
+```
+
+**Watch for:**
+- Pod restarts (RESTARTS counter increasing)
+- Increased error logs
+- Resource usage spikes
+- Service unreachability
+
+### 7.2 First 30 Minutes: Monitor Dashboard
+
+Keep dashboard visible showing:
+- Pod health status
+- CPU/Memory usage per pod
+- Request latency (if available)
+- Error rate
+- Recent logs
+
+**Alert triggers for immediate action:**
+- Any pod restarting repeatedly
+- Error rate above 5%
+- Latency above 2x normal
+- Pod stuck in Pending state
+
+### 7.3 First 2 Hours: Regular Checks
+
+```bash
+# Every 10 minutes:
+1. kubectl get pods -n $NAMESPACE
+2. kubectl top pods -n $NAMESPACE
+3. Check error logs: grep -i error from recent logs
+4. Check alerts dashboard
+```
+
+**If issues detected**, proceed to Incident Response Runbook
+
+### 7.4 After 2 Hours: Normal Monitoring
+
+Return to standard monitoring procedures. Deployment complete.
+
+---
+
+## If Issues Detected: Quick Rollback
+
+If problems occur at any point:
+
+```bash
+# IMMEDIATE: Rollback (1 minute)
+for deployment in vapora-backend vapora-agents vapora-llm-router; do
+  kubectl rollout undo deployment/$deployment -n $NAMESPACE &
+done
+wait
+
+# Verify rollback completing:
+kubectl rollout status deployment/vapora-backend -n $NAMESPACE --timeout=5m
+
+# Confirm services recovering:
+curl http://localhost:8001/health
+
+# Post to #deployments:
+# 🔙 ROLLBACK EXECUTED
+# Issue detected, services rolled back to previous version
+# All pods should be recovering now
+```
+
+See [Rollback Runbook](./rollback-runbook.md) for detailed procedures.
+
+---
+
+## Common Issues & Solutions
+
+### Issue: Pod stuck in ImagePullBackOff
+
+**Cause**: Docker image doesn't exist or can't be downloaded
+
+**Solution**:
+```bash
+# Check pod events
+kubectl describe pod <pod-name> -n $NAMESPACE
+
+# Check image registry access
+kubectl get secret -n $NAMESPACE
+
+# Either:
+1. Verify image name is correct in deployment.yaml
+2. Push missing image to registry
+3. Rollback deployment
+```
+
+### Issue: Pod stuck in CrashLoopBackOff
+
+**Cause**: Application crashing on startup
+
+**Solution**:
+```bash
+# Get pod logs
+kubectl logs <pod-name> -n $NAMESPACE --previous
+
+# Fix typically requires config change:
+1. Fix ConfigMap issue
+2. Re-apply ConfigMap: kubectl apply -f configmap.yaml
+3. Trigger pod restart: kubectl rollout restart deployment/<name>
+
+# Or rollback if unclear
+```
+
+### Issue: Pod in Pending state
+
+**Cause**: Node doesn't have capacity or resources
+
+**Solution**:
+```bash
+# Describe pod to see why
+kubectl describe pod <pod-name> -n $NAMESPACE
+
+# Check for "Insufficient cpu", "Insufficient memory"
+kubectl top nodes
+
+# Either:
+1. Scale down other workloads
+2. Increase node count
+3. Reduce resource requirements in deployment.yaml and redeploy
+```
+
+### Issue: Service endpoints empty
+
+**Cause**: Pods not passing health checks
+
+**Solution**:
+```bash
+# Check pod logs for errors
+kubectl logs <pod-name> -n $NAMESPACE
+
+# Check pod readiness probe failures
+kubectl describe pod <pod-name> -n $NAMESPACE | grep -A 5 "Readiness"
+
+# Fix configuration or rollback
+```
