+# DocFast Backup & Disaster Recovery Procedures
+
+## Overview
+DocFast now uses BorgBackup for full disaster recovery backups. The system backs up all critical components needed to restore the service on a new server.
+
+## What is Backed Up
+- **PostgreSQL database** - Full database dump with schema and data
+- **Docker volumes** - Application data and files
+- **Nginx configuration** - Web server configuration
+- **SSL certificates** - Let's Encrypt certificates and keys
+- **Crontabs** - Scheduled tasks
+- **OpenDKIM keys** - Email authentication keys
+- **DocFast application files** - docker-compose.yml, .env, scripts
+- **System information** - Installed packages, enabled services, disk usage
+
+## Backup Location & Schedule
+
+### Current Setup (Local)
+- **Location**: `/opt/borg-backups/docfast`
+- **Schedule**: Daily at 03:00 UTC
+- **Retention**: 7 daily + 4 weekly + 3 monthly backups
+- **Compression**: LZ4 (fast compression/decompression)
+- **Encryption**: repokey mode (encrypted with passphrase)
+
+### Security
+- **Passphrase**: `docfast-backup-YYYY` (where YYYY is current year)
+- **Key backup**: Stored in `/opt/borg-backups/docfast-key-backup.txt`
+- **⚠️ IMPORTANT**: Both passphrase AND key are required for restore!
+
+## Scripts
+
+### Backup Script: `/opt/docfast-borg-backup.sh`
+- Automated backup creation
+- Runs via cron daily at 03:00 UTC
+- Logs to `/var/log/docfast-backup.log`
+- Auto-prunes old backups
+
+### Restore Script: `/opt/docfast-borg-restore.sh`
+- List available backups: `./docfast-borg-restore.sh list`
+- Restore specific backup: `./docfast-borg-restore.sh restore docfast-YYYY-MM-DD_HHMM`
+- Restore latest backup: `./docfast-borg-restore.sh restore latest`
+
+## Manual Backup Commands
+
+```bash
+# Run backup manually
+/opt/docfast-borg-backup.sh
+
+# List all backups
+export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
+borg list /opt/borg-backups/docfast
+
+# Show repository info
+borg info /opt/borg-backups/docfast
+
+# Show specific backup contents
+borg list /opt/borg-backups/docfast::docfast-2026-02-15_1103
+```
+
+## Disaster Recovery Procedure
+
+### Complete Server Rebuild
+If the entire server is lost, follow these steps on a new server:
+
+1. **Install dependencies**:
+   ```bash
+   apt update && apt install -y docker.io docker-compose postgresql-16 nginx borgbackup
+   systemctl enable postgresql docker
+   ```
+
+2. **Copy backup data**:
+   - Transfer `/opt/borg-backups/` directory to new server
+   - Transfer `/opt/borg-backups/docfast-key-backup.txt`
+
+3. **Import Borg key**:
+   ```bash
+   export BORG_PASSPHRASE="docfast-backup-2026"
+   borg key import /opt/borg-backups/docfast /opt/borg-backups/docfast-key-backup.txt
+   ```
+
+4. **Restore latest backup**:
+   ```bash
+   /opt/docfast-borg-restore.sh restore latest
+   ```
+
+5. **Follow manual restore steps** (shown by restore script):
+   - Stop services
+   - Restore database
+   - Restore configuration files
+   - Set permissions
+   - Start services
+
+### Database-Only Recovery
+If only the database needs restoration:
+
+```bash
+# Stop DocFast
+cd /opt/docfast && docker-compose down
+
+# Restore database
+export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
+cd /tmp
+borg extract /opt/borg-backups/docfast::docfast-YYYY-MM-DD_HHMM
+sudo -u postgres dropdb docfast
+sudo -u postgres createdb -O docfast docfast
+export PGPASSFILE="/root/.pgpass"
+pg_restore -d docfast /tmp/tmp/docfast-backup-*/docfast-db.dump
+
+# Restart DocFast
+cd /opt/docfast && docker-compose up -d
+```
+
+## Migration to Off-Site Storage
+
+### Option 1: Hetzner Storage Box (Recommended)
+Manual setup required (Hetzner Storage Box API not available):
+
+1. **Purchase Hetzner Storage Box**
+   - Minimum 10GB size
+   - Enable SSH access in Hetzner Console
+
+2. **Configure SSH access**:
+   ```bash
+   # Generate SSH key for storage box
+   ssh-keygen -t ed25519 -f /root/.ssh/hetzner-storage-box
+   
+   # Add public key to storage box in Hetzner Console
+   cat /root/.ssh/hetzner-storage-box.pub
+   ```
+
+3. **Update backup script**:
+   Change `BORG_REPO` in `/opt/docfast-borg-backup.sh`:
+   ```bash
+   BORG_REPO="ssh://uXXXXXX@uXXXXXX.your-storagebox.de:23/./docfast-backups"
+   ```
+
+4. **Initialize remote repository**:
+   ```bash
+   export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
+   borg init --encryption=repokey ssh://uXXXXXX@uXXXXXX.your-storagebox.de:23/./docfast-backups
+   ```
+
+### Option 2: AWS S3/Glacier
+Use rclone + borg for S3 storage (requires investor approval for AWS costs).
+
+## Monitoring & Maintenance
+
+### Check Backup Status
+```bash
+# View recent backup logs
+tail -f /var/log/docfast-backup.log
+
+# Check repository size and stats
+export BORG_PASSPHRASE="docfast-backup-$(date +%Y)"
+borg info /opt/borg-backups/docfast
+```
+
+### Manual Cleanup
+```bash
+# Prune old backups manually
+borg prune --keep-daily 7 --keep-weekly 4 --keep-monthly 3 /opt/borg-backups/docfast
+
+# Compact repository
+borg compact /opt/borg-backups/docfast
+```
+
+### Repository Health Check
+```bash
+# Check repository consistency
+borg check --verify-data /opt/borg-backups/docfast
+```
+
+## Important Notes
+
+1. **Test restores regularly** - Run restore test monthly
+2. **Monitor backup logs** - Check for failures in `/var/log/docfast-backup.log`
+3. **Keep key safe** - Store `/opt/borg-backups/docfast-key-backup.txt` securely off-site
+4. **Update passphrase annually** - Change to new year format when year changes
+5. **Local storage limit** - Current server has ~19GB available, monitor usage
+
+## Migration Timeline
+- **Immediate**: Local BorgBackup operational (✅ Complete)
+- **Phase 2**: Off-site storage setup (requires Storage Box purchase or AWS approval)
+- **Phase 3**: Automated off-site testing and monitoring

+# DocFast CI/CD Pipeline Setup - COMPLETED ✅
+
+## What Was Implemented
+
+### ✅ Forgejo Actions Workflow
+- **File**: `.forgejo/workflows/deploy.yml`
+- **Trigger**: Push to `main` branch
+- **Process**: 
+  1. SSH to production server (167.235.156.214)
+  2. Pull latest code from git
+  3. Tag current Docker image for rollback (`rollback-YYYYMMDD-HHMMSS`)
+  4. Build new Docker image with `--no-cache`
+  5. Stop current services (30s graceful timeout)
+  6. Start new services with `docker compose up -d`
+  7. Health check at `http://127.0.0.1:3100/health` (30 attempts, 5s intervals)
+  8. **Auto-rollback** if health check fails
+  9. Cleanup old rollback images (keeps last 5)
+
+### ✅ Rollback Mechanism
+- **Automatic**: Built into the deployment workflow
+- **Manual Script**: `scripts/rollback.sh` for emergency use
+- **Image Tagging**: Previous images tagged with timestamps
+- **Auto-cleanup**: Removes old rollback images automatically
+
+### ✅ Documentation
+- **`DEPLOYMENT.md`**: Complete deployment guide
+- **`CI-CD-SETUP-COMPLETE.md`**: This summary
+- **Inline comments**: Detailed workflow documentation
+
+### ✅ Git Integration
+- Repository: `git@git.cloonar.com:openclawd/docfast.git` 
+- SSH access configured with key: `/home/openclaw/.ssh/docfast`
+- All CI/CD files committed and pushed successfully
+
+## What Needs Manual Setup (5 minutes)
+
+### 🔧 Repository Secrets
+Go to: https://git.cloonar.com/openclawd/docfast/settings/actions/secrets
+
+Add these 3 secrets:
+1. **SERVER_HOST**: `167.235.156.214`
+2. **SERVER_USER**: `root`  
+3. **SSH_PRIVATE_KEY**: (copy content from `/home/openclaw/.ssh/docfast`)
+
+### 🧪 Test the Pipeline
+1. Once secrets are added, push any change to main branch
+2. Check Actions tab: https://git.cloonar.com/openclawd/docfast/actions
+3. Watch deployment progress
+4. Verify with: `curl http://127.0.0.1:3100/health`
+
+## How to Trigger Deployments
+
+- **Automatic**: Any push to `main` branch
+- **Manual**: Push a trivial change (already prepared: VERSION file)
+
+## How to Rollback
+
+### Automatic Rollback
+- Happens automatically if new deployment fails health checks
+- No manual intervention required
+
+### Manual Rollback Options
+```bash
+# Option 1: Use the rollback script
+ssh root@167.235.156.214
+cd /root/docfast  
+./scripts/rollback.sh
+
+# Option 2: Manual Docker commands
+ssh root@167.235.156.214
+docker compose down
+docker images | grep rollback  # Find latest rollback image
+docker tag docfast-docfast:rollback-YYYYMMDD-HHMMSS docfast-docfast:latest
+docker compose up -d
+```
+
+## Monitoring Commands
+
+```bash
+# Health check
+curl http://127.0.0.1:3100/health
+
+# Service status  
+docker compose ps
+
+# View logs
+docker compose logs -f docfast
+
+# Check rollback images available
+docker images | grep docfast-docfast
+```
+
+## Files Added/Modified
+
+```
+.forgejo/workflows/deploy.yml    # Main deployment workflow
+scripts/rollback.sh             # Emergency rollback script
+scripts/setup-secrets.sh        # Helper script (API had auth issues)
+DEPLOYMENT.md                   # Deployment documentation  
+CI-CD-SETUP-COMPLETE.md        # This summary
+VERSION                         # Test file for pipeline testing
+```
+
+## Next Steps
+
+1. **Set up secrets** in Forgejo (5 minutes)
+2. **Test deployment** by making a small change
+3. **Verify** the health check endpoint works
+4. **Document** any environment-specific adjustments needed
+
+## Success Criteria ✅
+
+- [x] Forgejo Actions available and configured
+- [x] Deployment workflow created and tested (syntax)
+- [x] Rollback mechanism implemented (automatic + manual)
+- [x] Health check integration (`/health` endpoint)  
+- [x] Git repository integration working
+- [x] Documentation complete
+- [x] Test change ready for pipeline verification
+
+**Ready for production use once secrets are configured!** 🚀

+# DocFast CI/CD Deployment
+
+This repository uses Forgejo Actions for automated deployment to production.
+
+## Setup Instructions
+
+### 1. Repository Secrets
+
+Go to repository settings → Actions → Secrets and add these secrets:
+
+- **SERVER_HOST**: `167.235.156.214`
+- **SERVER_USER**: `root`
+- **SSH_PRIVATE_KEY**: The private SSH key content from `/home/openclaw/.ssh/docfast`
+
+### 2. How Deployment Works
+
+**Trigger**: Push to `main` branch
+**Process**:
+1. SSH to production server
+2. Pull latest code from git
+3. Tag current Docker image for rollback
+4. Build new Docker image
+5. Stop current services
+6. Start new services
+7. Health check at `http://127.0.0.1:3100/health`
+8. Rollback automatically if health check fails
+
+### 3. Rollback Procedure
+
+**Automatic Rollback**:
+- Happens automatically if deployment fails health checks
+- Reverts to the previously tagged image
+
+**Manual Rollback**:
+```bash
+# On the production server
+cd /root/docfast
+./scripts/rollback.sh
+```
+
+**Emergency Rollback via SSH**:
+```bash
+ssh root@167.235.156.214
+cd /root/docfast
+docker compose down
+docker tag docfast-docfast:rollback-YYYYMMDD-HHMMSS docfast-docfast:latest
+docker compose up -d
+```
+
+### 4. Monitoring
+
+- **Health Check**: `curl http://127.0.0.1:3100/health`
+- **Service Status**: `docker compose ps`
+- **Logs**: `docker compose logs -f`
+
+### 5. File Structure
+
+```
+.forgejo/workflows/deploy.yml  # Main deployment workflow
+scripts/rollback.sh           # Manual rollback script  
+scripts/setup-secrets.sh      # Helper for setting up secrets
+DEPLOYMENT.md                 # This documentation
+```
+
+### 6. Testing the Pipeline
+
+1. Make a small change (e.g., bump version comment)
+2. Commit and push to main branch
+3. Check Actions tab in Forgejo to see deployment progress
+4. Verify service is running with `curl http://127.0.0.1:3100/health`
+
+## Troubleshooting
+
+- **SSH Issues**: Ensure SSH key is properly added to secrets
+- **Docker Build Issues**: Check server has enough disk space and memory
+- **Health Check Fails**: Check if service is binding to correct port (3100)
+- **Permission Issues**: Ensure user has Docker privileges on server

+## Open
+
+### BUG-030: Email change backend not implemented
+- **Severity:** High
+- **Found:** 2026-02-14 QA session
+- **Description:** Frontend UI for email change is deployed (modal, form, JS handlers), but no backend routes exist. Frontend calls `/v1/email-change` and `/v1/email-change/verify` which return 404.
+- **Impact:** Users see "Change Email" link in footer but the feature doesn't work.
+- **Fix:** Implement `src/routes/email-change.ts` with verification code flow similar to signup/recover.
+
+### BUG-031: Stray file "\001@" in repository
+- **Severity:** Low
+- **Found:** 2026-02-14
+- **Description:** An accidental file named `\001@` was committed to the repo.
+- **Fix:** `git rm "\001@"` and commit.
+
+### BUG-032: Swagger UI content not rendered via web_fetch
+- **Severity:** Low (cosmetic)
+- **Found:** 2026-02-14
+- **Description:** /docs page loads (200) and has swagger-ui assets, but content is JS-rendered so web_fetch can't verify full render. Needs browser-based QA for full verification.

+# DocFast Decisions Log
+
+## 2026-02-14: Mandatory QA After Every Deployment
+
+**Rule:** Every deployment MUST be followed by a full QA session. No exceptions.
+
+**QA Checklist:**
+- Landing page loads, zero console errors
+- Signup flow works (email verification)
+- Key recovery flow works
+- Email change flow works (when backend is implemented)
+- Swagger UI loads at /docs
+- API endpoints work (HTML→PDF, Markdown→PDF, URL→PDF)
+- Health endpoint returns ok
+- All previous features still working
+
+**Rationale:** Code was deployed to production without verification multiple times, leading to broken features being live. QA catches regressions before users do.
+
+## 2026-02-14: Code Must Be Committed Before Deployment
+
+Changes were found uncommitted on the production server. All code changes must be committed and pushed to Forgejo before deploying.

+# DocFast Infrastructure Guide
+
+Complete disaster recovery and deployment guide for DocFast.
+
+## Quick Start (New Server Deployment)
+
+### 1. Prerequisites
+
+- Fresh Ubuntu 24.04 LTS server
+- Root access
+- Domain name pointing to server IP
+- Stripe account with webhook configured
+
+### 2. Automated Setup
+
+```bash
+# Clone the repository
+git clone ssh://forgejo@git.cloonar.com/openclawd/docfast.git
+cd docfast/infrastructure
+
+# Run the setup script as root
+chmod +x setup.sh
+./setup.sh
+
+# Follow the post-setup instructions
+```
+
+### 3. Manual Configuration Required
+
+After running `setup.sh`, complete these manual steps:
+
+#### SSL Certificate
+```bash
+certbot --nginx -d docfast.dev -d www.docfast.dev
+```
+
+#### DKIM DNS Record
+Add this TXT record to your DNS:
+```
+mail._domainkey.docfast.dev
+```
+Get the value from: `/etc/opendkim/keys/docfast.dev/mail.txt`
+
+#### Environment Variables
+```bash
+cd /opt/docfast
+cp infrastructure/.env.template .env
+# Edit .env with real values
+```
+
+#### Start the Application
+```bash
+cd /opt/docfast
+cp infrastructure/docker-compose.yml .
+docker-compose up -d
+```
+
+## Complete Manual Setup (Step by Step)
+
+If the automated script fails or you prefer manual setup:
+
+### System Packages
+```bash
+apt update && apt upgrade -y
+apt install -y nginx postfix opendkim opendkim-tools certbot \
+    python3-certbot-nginx ufw docker.io docker-compose-plugin \
+    git sqlite3 postgresql postgresql-contrib
+```
+
+### Firewall Configuration
+```bash
+ufw --force enable
+ufw default deny incoming
+ufw default allow outgoing
+ufw allow ssh
+ufw allow 80/tcp
+ufw allow 443/tcp
+ufw allow from 172.16.0.0/12 to any port 25 comment "Docker SMTP relay"
+ufw allow from 172.16.0.0/12 to any port 5432 comment "Docker PostgreSQL"
+```
+
+### PostgreSQL Setup
+```bash
+sudo -u postgres createuser -D -A -P docfast
+sudo -u postgres createdb -O docfast docfast
+
+# Edit /etc/postgresql/16/main/postgresql.conf
+echo "listen_addresses = '*'" >> /etc/postgresql/16/main/postgresql.conf
+
+# Edit /etc/postgresql/16/main/pg_hba.conf
+echo "host docfast docfast 172.17.0.0/16 md5" >> /etc/postgresql/16/main/pg_hba.conf
+echo "host docfast docfast 172.18.0.0/16 md5" >> /etc/postgresql/16/main/pg_hba.conf
+
+systemctl restart postgresql
+```
+
+### Nginx Configuration
+```bash
+cp nginx/docfast.dev /etc/nginx/sites-available/
+ln -s /etc/nginx/sites-available/docfast.dev /etc/nginx/sites-enabled/
+rm /etc/nginx/sites-enabled/default
+nginx -t
+systemctl reload nginx
+```
+
+### Postfix & OpenDKIM
+```bash
+cp postfix/main.cf /etc/postfix/
+cp postfix/opendkim.conf /etc/opendkim.conf
+cp postfix/TrustedHosts /etc/opendkim/
+
+# Generate DKIM keys
+mkdir -p /etc/opendkim/keys/docfast.dev
+cd /etc/opendkim/keys/docfast.dev
+opendkim-genkey -s mail -d docfast.dev
+chown opendkim:opendkim mail.private mail.txt
+chmod 600 mail.private
+
+systemctl restart postfix opendkim
+```
+
+### Application Deployment
+```bash
+useradd -r -m -s /bin/bash docfast
+usermod -aG docker docfast
+mkdir -p /opt/docfast
+chown docfast:docfast /opt/docfast
+
+cd /opt/docfast
+# Copy your source code here
+cp infrastructure/docker-compose.yml .
+cp infrastructure/.env.template .env
+# Edit .env with real values
+
+docker-compose up -d
+```
+
+### Backup System
+```bash
+# Install BorgBackup
+apt install -y borgbackup
+
+# Create backup directories
+mkdir -p /opt/docfast-backups /opt/borg-backups
+
+# Copy backup scripts
+cp scripts/docfast-backup.sh /opt/
+cp scripts/borg-backup.sh /opt/
+cp scripts/borg-restore.sh /opt/
+cp scripts/rollback.sh /opt/
+chmod +x /opt/docfast-backup.sh /opt/borg-backup.sh /opt/borg-restore.sh /opt/rollback.sh
+
+# Add to root crontab
+echo "0 */6 * * * /opt/docfast-backup.sh >> /var/log/docfast-backup.log 2>&1" | crontab -
+echo "0 3 * * * /opt/borg-backup.sh >> /var/log/borg-backup.log 2>&1" | crontab -
+```
+
+## Backup Strategy
+
+DocFast uses a two-tier backup strategy for comprehensive data protection:
+
+### 1. SQLite Database Backups (Every 6 hours)
+- **Script**: `/opt/docfast-backup.sh`
+- **Frequency**: Every 6 hours via cron
+- **Retention**: 7 days of backups (28 files), plus 4 weekly copies
+- **Storage**: `/opt/docfast-backups/`
+- **Method**: SQLite `.backup` command with integrity verification
+
+### 2. Complete System Backups (Daily)
+- **Script**: `/opt/borg-backup.sh` 
+- **Frequency**: Daily at 03:00 UTC via cron
+- **Retention**: 7 daily + 4 weekly + 3 monthly
+- **Storage**: `/opt/borg-backups/docfast`
+- **Includes**:
+  - PostgreSQL database dump
+  - Docker volumes (complete application data)
+  - Nginx configuration
+  - SSL certificates (Let's Encrypt)
+  - OpenDKIM keys and configuration
+  - Cron jobs and system configurations
+  - Application files (.env, docker-compose.yml)
+  - System information (packages, services)
+
+### Backup Management Commands
+```bash
+# List available Borg backups
+/opt/borg-restore.sh list
+
+# Restore from latest backup (creates restore directory)
+/opt/borg-restore.sh restore latest
+
+# Restore from specific backup
+/opt/borg-restore.sh restore docfast-2026-02-15_0300
+
+# Quick rollback (Docker image only)
+/opt/rollback.sh
+```
+
+## Disaster Recovery Procedures
+
+### Complete Server Failure
+
+1. **Provision new server** with same OS version
+2. **Run setup script** from this repository
+3. **Restore DNS** records to point to new server
+4. **Copy backups** from off-site storage to `/opt/docfast-backups/`
+5. **Restore database**:
+   ```bash
+   docker-compose down
+   docker volume rm docfast_docfast-data
+   docker volume create docfast_docfast-data
+   cp /opt/docfast-backups/docfast-weekly-LATEST.db \
+      /var/lib/docker/volumes/docfast_docfast-data/_data/docfast.db
+   docker-compose up -d
+   ```
+6. **Verify SSL certificates** with `certbot certificates`
+7. **Test email delivery** and DKIM signing
+
+### Database Corruption
+
+```bash
+cd /opt/docfast
+docker-compose down
+
+# Find latest good backup
+ls -la /opt/docfast-backups/
+
+# Restore from backup
+cp /opt/docfast-backups/docfast-daily-LATEST.db \
+   /var/lib/docker/volumes/docfast_docfast-data/_data/docfast.db
+
+docker-compose up -d
+```
+
+### Email Delivery Issues
+
+Check DKIM setup:
+```bash
+# Verify DKIM key is readable
+sudo -u opendkim cat /etc/opendkim/keys/docfast.dev/mail.private
+
+# Check OpenDKIM is signing
+tail -f /var/log/mail.log
+
+# Test email sending
+echo "Test email" | mail -s "Test" test@example.com
+```
+
+### SSL Certificate Issues
+
+```bash
+# Check certificate status
+certbot certificates
+
+# Renew if needed
+certbot renew --dry-run
+certbot renew
+
+# Fix nginx config if needed
+nginx -t
+systemctl reload nginx
+```
+
+## Monitoring & Maintenance
+
+### Daily Checks
+- [ ] Application health: `curl https://docfast.dev/health`
+- [ ] Docker containers: `docker ps`
+- [ ] Disk space: `df -h`
+- [ ] Backup status: `ls -la /opt/docfast-backups/`
+
+### Weekly Checks
+- [ ] SSL certificate expiry: `certbot certificates`
+- [ ] Email delivery test
+- [ ] System updates: `apt list --upgradable`
+- [ ] Log rotation: `du -sh /var/log/`
+
+### Monthly Tasks
+- [ ] Review backup retention
+- [ ] Update system packages
+- [ ] Review firewall rules: `ufw status`
+- [ ] Check for failed login attempts: `grep "Failed password" /var/log/auth.log`
+
+## Environment Variables Reference
+
+| Variable | Required | Description | Example |
+|----------|----------|-------------|---------|
+| `STRIPE_SECRET_KEY` | ✅ | Stripe API secret key | `sk_live_...` |
+| `STRIPE_WEBHOOK_SECRET` | ✅ | Stripe webhook endpoint secret | `whsec_...` |
+| `BASE_URL` | ✅ | Application base URL | `https://docfast.dev` |
+| `API_KEYS` | ✅ | Comma-separated API keys | `key1,key2,key3` |
+| `PRO_KEYS` | ✅ | Comma-separated pro API keys | `prokey1,prokey2` |
+| `DATABASE_PASSWORD` | ✅ | PostgreSQL password | `secure_password_123` |
+
+## DNS Records Required
+
+| Type | Name | Value | TTL |
+|------|------|-------|-----|
+| A | docfast.dev | SERVER_IP | 300 |
+| A | www.docfast.dev | SERVER_IP | 300 |
+| TXT | mail._domainkey.docfast.dev | DKIM_PUBLIC_KEY | 300 |
+| MX | docfast.dev | docfast.dev | 300 |
+| TXT | docfast.dev | v=spf1 mx ~all | 300 |
+
+## Stripe Configuration
+
+Required webhook events:
+- `checkout.session.completed`
+- `invoice.payment_succeeded`
+- `customer.subscription.created`
+- `customer.subscription.updated`
+- `customer.subscription.deleted`
+
+Webhook URL: `https://docfast.dev/api/stripe/webhook`
+
+## Security Considerations
+
+- Server runs on non-standard SSH port (change from 22)
+- Fail2ban recommended for brute force protection
+- Regular security updates via unattended-upgrades
+- Database backups encrypted at rest
+- API keys rotated regularly
+- Monitor application logs for suspicious activity
+
+## Troubleshooting
+
+### Common Issues
+
+**Container won't start**: Check logs with `docker-compose logs -f`
+
+**Database connection errors**: Verify PostgreSQL is running and Docker networks are configured
+
+**Email not sending**: Check postfix logs: `tail -f /var/log/mail.log`
+
+**SSL certificate errors**: Verify domain DNS and run `certbot --nginx`
+
+**High memory usage**: Monitor with `docker stats` and adjust container limits
+
+### Log Locations
+- Application: `docker-compose logs`
+- Nginx: `/var/log/nginx/`
+- Postfix: `/var/log/mail.log`
+- System: `/var/log/syslog`
+- Backups: `/var/log/docfast-backup.log`

+# DocFast Sessions Log
+
+## 2026-02-14 22:14 UTC — Deployment + QA Session
+
+**Trigger:** Latest code changes (Swagger UI, key recovery UI, email change) were not deployed despite being in the working tree.
+
+**Actions:**
+1. SSH'd into server (167.235.156.214)
+2. Found uncommitted changes in working tree (email change UI, Swagger UI, key recovery link)
+3. Committed all changes: `d859e9f` — "feat: email change UI, Swagger UI improvements, key recovery link on landing page"
+4. Pushed to Forgejo (openclawd/docfast)
+5. Rebuilt container with `docker compose build --no-cache`
+6. Restarted: `docker compose up -d`
+7. Verified server healthy: 15-page browser pool, version 0.2.1
+
+**QA Results:**
+| Test | Result |
+|------|--------|
+| Landing page loads | ✅ 200 OK |
+| Key recovery link on landing | ✅ Present |
+| Email change link in footer | ✅ Present |
+| Swagger UI at /docs | ✅ 200 OK |
+| Signup endpoint | ✅ Works (verification_required) |
+| Key recovery endpoint | ✅ Works (recovery_sent) |
+| Email change backend | ❌ NOT IMPLEMENTED (BUG-030) |
+| HTML→PDF conversion | ✅ Valid PDF |
+| Markdown→PDF conversion | ✅ Valid PDF |
+| URL→PDF conversion | ✅ Valid PDF |
+| Health endpoint | ✅ Pool: 15 pages, 0 active |
+| Browser pool | ✅ 1 browser × 15 pages |
+
+**Bugs Found:**
+- BUG-030: Email change backend not implemented (frontend-only)
+- BUG-031: Stray `\001@` file in repo
+- BUG-032: Swagger UI needs browser QA for full verification
+
+**Note:** Browser-based QA not available (openclaw browser service unreachable). Console error check, mobile responsive test, and full Swagger UI render verification deferred.
