+# Superball Thrower Deployment Plan
+
+## Overview
+
+This document provides a complete deployment plan for the Superball Thrower C implementation on your server (accessible via `sshlt`).
+
+## Deployment Architecture
+
+- **Binary Location**: `/usr/local/bin/super_ball_thrower/superball_thrower`
+- **Config Location**: `/usr/local/bin/super_ball_thrower/config.json`
+- **Service User**: `superball-thrower`
+- **Service Name**: `superball-thrower.service`
+- **Log Location**: `/var/log/superball-thrower/`
+
+## One-Time Server Setup
+
+### Step 1: Create setup_server.sh
+
+Create this file on your local machine:
+
+```bash
+#!/bin/bash
+# One-time server setup script for Superball Thrower
+# Run this on the server as root or with sudo
+
+set -e
+
+echo "=== Superball Thrower Server Setup ==="
+
+# Create user if it doesn't exist
+if ! id -u superball-thrower >/dev/null 2>&1; then
+    echo "Creating user superball-thrower..."
+    useradd -r -s /bin/bash -d /usr/local/bin/super_ball_thrower superball-thrower
+else
+    echo "User superball-thrower already exists"
+fi
+
+# Create directory structure
+echo "Creating directory structure..."
+mkdir -p /usr/local/bin/super_ball_thrower
+mkdir -p /var/log/superball-thrower
+
+# Set ownership
+echo "Setting ownership..."
+chown -R superball-thrower:superball-thrower /usr/local/bin/super_ball_thrower
+chown -R superball-thrower:superball-thrower /var/log/superball-thrower
+
+# Set permissions
+echo "Setting permissions..."
+chmod 755 /usr/local/bin/super_ball_thrower
+chmod 755 /var/log/superball-thrower
+
+echo ""
+echo "=== Setup Complete ==="
+echo ""
+echo "Next steps:"
+echo "1. Copy your config.json to /usr/local/bin/super_ball_thrower/"
+echo "2. Install the systemd service file"
+echo "3. Run the deploy_lt.sh script to build and deploy the binary"
+```
+
+### Step 2: Create superball-thrower.service
+
+Create this systemd service file:
+
+```ini

+```
+
+### Step 3: Run Setup Commands
+
+Execute these commands on the server:
+
+```bash
+# SSH into the server
+sshlt
+
+# Copy the setup script to the server (or create it there)
+# Then run it:
+sudo bash setup_server.sh
+
+# Install the systemd service file
+sudo cp superball-thrower.service /etc/systemd/system/
+sudo chmod 644 /etc/systemd/system/superball-thrower.service
+sudo systemctl daemon-reload
+sudo systemctl enable superball-thrower
+
+# Copy your config.json to the deployment directory
+sudo cp config.json /usr/local/bin/super_ball_thrower/
+sudo chown superball-thrower:superball-thrower /usr/local/bin/super_ball_thrower/config.json
+sudo chmod 600 /usr/local/bin/super_ball_thrower/config.json
+```
+
+## Deployment Script
+
+### deploy_lt.sh
+
+Create this script in your project root:
+
+```bash

+```
+
+## Deployment Workflow
+
+### Initial Deployment
+
+1. **Prepare the server** (one-time):
+   ```bash
+   # Create and run setup_server.sh on the server
+   sshlt
+   # Run the setup commands from Step 3 above
+   ```
+
+2. **Deploy the application**:
+   ```bash
+   # From your local project directory
+   chmod +x deploy_lt.sh
+   ./deploy_lt.sh
+   ```
+
+### Subsequent Deployments
+
+After making code changes:
+
+```bash
+# Just run the deployment script
+./deploy_lt.sh
+```
+
+The script will:
+- Build the binary locally
+- Stop the service
+- Deploy the new binary
+- Restart the service
+- Show the service status
+
+## Monitoring and Maintenance
+
+### View Logs
+
+```bash
+# Real-time logs
+ssh sshlt 'sudo journalctl -u superball-thrower -f'
+
+# Last 100 lines
+ssh sshlt 'sudo journalctl -u superball-thrower -n 100'
+
+# Logs since boot
+ssh sshlt 'sudo journalctl -u superball-thrower -b'
+```
+
+### Service Management
+
+```bash
+# Check status
+ssh sshlt 'sudo systemctl status superball-thrower'
+
+# Restart service
+ssh sshlt 'sudo systemctl restart superball-thrower'
+
+# Stop service
+ssh sshlt 'sudo systemctl stop superball-thrower'
+
+# Start service
+ssh sshlt 'sudo systemctl start superball-thrower'
+
+# Disable service (prevent auto-start)
+ssh sshlt 'sudo systemctl disable superball-thrower'
+
+# Enable service (auto-start on boot)
+ssh sshlt 'sudo systemctl enable superball-thrower'
+```
+
+### Update Configuration
+
+```bash
+# Edit config on server
+ssh sshlt 'sudo nano /usr/local/bin/super_ball_thrower/config.json'
+
+# Or copy from local
+scp config.json sshlt:/tmp/config.json
+ssh sshlt 'sudo mv /tmp/config.json /usr/local/bin/super_ball_thrower/config.json && \
+           sudo chown superball-thrower:superball-thrower /usr/local/bin/super_ball_thrower/config.json && \
+           sudo chmod 600 /usr/local/bin/super_ball_thrower/config.json'
+
+# Restart to apply changes
+ssh sshlt 'sudo systemctl restart superball-thrower'
+```
+
+## Troubleshooting
+
+### Service Won't Start
+
+```bash
+# Check detailed status
+ssh sshlt 'sudo systemctl status superball-thrower -l'
+
+# Check recent logs
+ssh sshlt 'sudo journalctl -u superball-thrower -n 50'
+
+# Test binary manually
+ssh sshlt 'sudo -u superball-thrower /usr/local/bin/super_ball_thrower/superball_thrower /usr/local/bin/super_ball_thrower/config.json'
+```
+
+### Permission Issues
+
+```bash
+# Fix ownership
+ssh sshlt 'sudo chown -R superball-thrower:superball-thrower /usr/local/bin/super_ball_thrower'
+
+# Fix permissions
+ssh sshlt 'sudo chmod 755 /usr/local/bin/super_ball_thrower && \
+           sudo chmod 755 /usr/local/bin/super_ball_thrower/superball_thrower && \
+           sudo chmod 600 /usr/local/bin/super_ball_thrower/config.json'
+```
+
+### Build Issues
+
+```bash
+# Clean and rebuild
+make distclean
+make
+
+# Check dependencies
+cd nostr_core_lib && ./build.sh --nips=1,6,44
+```
+
+## Security Considerations
+
+1. **Config File**: Contains private key - ensure it's only readable by superball-thrower user (chmod 600)
+2. **Service User**: Runs as non-root user with restricted permissions
+3. **Systemd Hardening**: Service file includes security restrictions
+4. **Log Access**: Only root and superball-thrower can read logs
+
+## Backup and Recovery
+
+### Backup Configuration
+
+```bash
+# Backup config from server
+scp sshlt:/usr/local/bin/super_ball_thrower/config.json ./config.backup.json
+```
+
+### Restore Configuration
+
+```bash
+# Restore config to server
+scp ./config.backup.json sshlt:/tmp/config.json
+ssh sshlt 'sudo mv /tmp/config.json /usr/local/bin/super_ball_thrower/config.json && \
+           sudo chown superball-thrower:superball-thrower /usr/local/bin/super_ball_thrower/config.json && \
+           sudo chmod 600 /usr/local/bin/super_ball_thrower/config.json && \
+           sudo systemctl restart superball-thrower'
+```
+
+## Next Steps
+
+After reviewing this plan:
+
+1. Switch to Code mode to create the actual script files
+2. Run the one-time setup on the server
+3. Test the deployment script
+4. Monitor the service to ensure it's running correctly

+# Test Suite Quick Start Guide
+
+## Prerequisites
+
+1. **Install nak** (Nostr Army Knife):
+   ```bash
+   go install github.com/fiatjaf/nak@latest
+   ```
+
+2. **Build the daemon**:
+   ```bash
+   cd ..
+   make
+   ```
+
+## Quick Test Run
+
+### 1. Single Test (No Thrower Required)
+
+Test the framework itself:
+```bash
+cd tests
+./test_framework.sh list
+```
+
+### 2. Single-Hop Test (1 Thrower)
+
+**Setup Thrower A:**
+```bash
+# In terminal 1 - Create config
+cd ..
+cat > config_test_a.json <<EOF
+{
+  "thrower": {

+cd tests
+./test_framework.sh test_multi_hop
+./test_framework.sh test_padding
+./test_framework.sh test_end_to_end
+```
+
+### 4. Run All Tests
+
+With all 3 throwers running:
+```bash
+cd tests
+./test_framework.sh all
+```
+
+## Test Timing
+
+All tests use 2-second delays for fast execution:
+- **test_single_hop**: ~10 seconds
+- **test_multi_hop**: ~15 seconds  
+- **test_padding**: ~12 seconds
+- **test_delays**: ~20 seconds (tests multiple delay values)
+- **test_thrower_info**: ~10 seconds
+- **test_relay_auth**: ~5 seconds (skipped if no AUTH relay)
+- **test_end_to_end**: ~15 seconds
+
+**Total suite runtime**: ~1-2 minutes (with all throwers running)
+
+## Troubleshooting
+
+### "nak command not found"
+```bash
+go install github.com/fiatjaf/nak@latest
+export PATH=$PATH:$(go env GOPATH)/bin
+```
+
+### "Event not found on relay"
+- Check thrower is running: `ps aux | grep superball_thrower`
+- Check thrower logs for errors
+- Verify relay connectivity: `nak req --relay wss://relay.laantungir.net -k 1 --limit 1`
+
+### "Event arrived too early"
+- Thrower may not be respecting delays
+- Check queue processing in logs
+- Verify system time is correct
+
+### Tests timeout
+- Increase timeout values in test scripts
+- Check network connectivity
+- Verify relays are responding
+
+## Test Keys
+
+⚠️ **WARNING**: Test keys in `fixtures/test_keys.json` are for testing only!
+
+- Builder: `0000...0001`
+- Thrower A: `0000...0002`
+- Thrower B: `0000...0003`
+- Thrower C: `0000...0004`
+
+**NEVER use these keys in production!**
+
+## Next Steps
+
+1. Run individual tests to verify each SUP
+2. Run full suite with `./test_framework.sh all`
+3. Check logs in `tests/logs/` for details
+4. Review results in `tests/results/summary.txt`

+# Superball Protocol Test Suite
+
+Comprehensive test suite for verifying SUP-01 through SUP-06 compliance in the Superball Thrower daemon.
+
+## Overview
+
+This test suite validates all aspects of the Superball protocol implementation:
+
+- **SUP-01**: Basic single-hop routing
+- **SUP-02**: Multi-hop routing (2-5 hops)
+- **SUP-03**: Padding payload handling (Type 2 payloads)
+- **SUP-04**: Delay and jitter verification
+- **SUP-05**: Relay authentication testing
+- **SUP-06**: Thrower information publishing
+
+## Prerequisites
+
+### Required Tools
+
+1. **nak** (Nostr Army Knife)
+   ```bash
+   go install github.com/fiatjaf/nak@latest
+   ```
+
+2. **jq** (JSON processor)
+   ```bash
+   sudo apt-get install jq  # Debian/Ubuntu
+   brew install jq          # macOS
+   ```
+
+3. **Superball Thrower daemon**
+   ```bash
+   cd ..
+   make
+   ```
+
+### Running Throwers
+
+For multi-hop tests, you need multiple thrower instances running. Create separate config files for each:
+
+```bash
+# Thrower A
+cp config.example.json config_thrower_a.json
+# Edit config_thrower_a.json with thrower_a private key
+
+# Thrower B
+cp config.example.json config_thrower_b.json
+# Edit config_thrower_b.json with thrower_b private key
+
+# Thrower C
+cp config.example.json config_thrower_c.json
+# Edit config_thrower_c.json with thrower_c private key
+```
+
+Start each thrower in a separate terminal:
+```bash
+./superball_thrower config_thrower_a.json
+./superball_thrower config_thrower_b.json
+./superball_thrower config_thrower_c.json
+```

+## Test Descriptions
+
+### test_single_hop.sh (SUP-01)
+
+Tests basic single-hop routing:
+- Builder creates encrypted event
+- Thrower receives and decrypts
+- Thrower waits for delay
+- Thrower posts to final relay
+- Verifies timing and content
+
+**Duration**: ~10-15 seconds  
+**Requirements**: 1 thrower running
+
+### test_multi_hop.sh (SUP-02)
+
+Tests multi-hop routing with 3 hops:
+- Creates onion-routed event (3 layers)
+- Each thrower unwraps one layer
+- Verifies complete routing chain
+- Checks cumulative delays
+
+**Duration**: ~30-45 seconds  
+**Requirements**: 3 throwers running (A, B, C)
+
+### test_padding.sh (SUP-03)

+- Verifies padding is discarded
+- Confirms content integrity
+
+**Duration**: ~15-20 seconds  
+**Requirements**: 2 throwers running (A, B)
+
+### test_delays.sh (SUP-04)
+
+Tests delay constraints with multiple values:
+- Tests delays: 0s, 5s, 10s, 30s, 60s
+- Verifies minimum delay respected
+- Checks jitter application
+- Validates timing accuracy
+
+**Duration**: ~2-3 minutes  
+**Requirements**: 1 thrower running
+
+### test_relay_auth.sh (SUP-05)
+
+Tests AUTH-required relay handling:

+- Verifies relay marked as "auth-required"
+- Confirms events skip AUTH relay
+- Checks appropriate logging
+
+**Duration**: ~5 seconds  
+**Requirements**: AUTH-required relay (optional)
+
+### test_thrower_info.sh (SUP-06)
+
+Tests thrower information publishing:
+- Queries for kind 12222 events
+- Verifies all required fields
+- Checks relay configurations
+- Validates event structure
+
+**Duration**: ~10-15 seconds  
+**Requirements**: 1 thrower running with auto-publish
+
+### test_end_to_end.sh
+
+Complete workflow test combining all features:
+- 3-hop routing chain
+- Padding at first hop
+- Delays at each hop
+- Full protocol compliance
+- Performance metrics
+
+**Duration**: ~30-45 seconds  
+**Requirements**: 3 throwers running (A, B, C)
+
+## Test Configuration
+
+### Test Keys
+
+Test keypairs are defined in `fixtures/test_keys.json`:
+- **builder**: Creates initial Superball events
+- **thrower_a**: First hop
+- **thrower_b**: Second hop
+- **thrower_c**: Third hop
+- **thrower_d**: Fourth hop (for 4-hop tests)
+- **thrower_e**: Fifth hop (for 5-hop tests)
+
+⚠️ **WARNING**: These are test keys only. NEVER use in production!
+
+### Test Relays
+
+Relay configurations are in `fixtures/test_relays.json`:
+- **primary**: wss://relay.laantungir.net
+- **secondary**: wss://relay.damus.io
+- **tertiary**: wss://nos.lol
+- **final**: wss://relay.nostr.band
+
+You can modify these to use your preferred relays.
+

+
+### Failure Output
+
+When a test fails, the last 20 lines of the log are displayed:
+
+```
+Running: test_single_hop
+✗ FAILED: test_single_hop (15s)
+  See log: logs/test_single_hop.log
+  Last 20 lines of log:
+    ERROR: Inner event not found on final relay within 30s
+    This could indicate:
+      - Thrower is not running
+      - Network connectivity issues
+```
+
+### Logs
+
+Detailed logs for each test are saved in `logs/`:
+- `logs/test_single_hop.log`
+- `logs/test_multi_hop.log`
+- etc.
+
+Results summary is saved in `results/summary.txt`.
+
+## Troubleshooting
+
+### Test Fails: "nak command not found"
+
+Install nak:
+```bash
+go install github.com/fiatjaf/nak@latest
+```
+
+### Test Fails: "superball_thrower binary not found"
+
+Build the daemon:
+```bash
+cd ..
+make
+```
+
+### Test Fails: "Event not found on relay"
+
+Possible causes:
+1. Thrower not running
+2. Wrong private key in config
+3. Relay connectivity issues
+4. Firewall blocking WebSocket connections
+
+Check thrower logs:
+```bash
+tail -f /tmp/superball_thrower.log
+```
+
+### Test Fails: "Event arrived too early"
+
+The thrower may not be respecting delay constraints. Check:
+1. Queue processing is working
+2. Delays are being applied
+3. System time is correct
+
+### Multi-hop Tests Fail
+
+Ensure all required throwers are running:
+```bash
+ps aux | grep superball_thrower
+```
+
+Each thrower needs its own config file with the correct private key.

+## Quick Commands
+
+```bash
+# List all tests
+./test_framework.sh list
+
+# Run all tests
+./test_framework.sh all
+
+# Run specific test
+./test_framework.sh test_single_hop
+
+# View help

+```
+
+## Test Parameters
+
+All tests use **2-second delays** for fast execution:
+- Single-hop: 2s delay
+- Multi-hop: 2s per hop (6s total for 3 hops)
+- Padding: 2s per hop
+- End-to-end: 2s per hop (6s total)
+
+## Success Criteria
+
+Each test verifies:
+1. ✓ Event routing completes successfully
+2. ✓ Timing constraints respected (delay >= specified)
+3. ✓ Content integrity maintained
+4. ✓ Event structure valid
+5. ✓ Protocol compliance (SUP-specific)
+
+## Test Keys (fixtures/test_keys.json)
+
+⚠️ **FOR TESTING ONLY - DO NOT USE IN PRODUCTION**
+
+| Role | Private Key | Public Key |
+|------|-------------|------------|
+| Builder | `0000...0001` | `79be667e...` |
+| Thrower A | `0000...0002` | `c6047f94...` |
+| Thrower B | `0000...0003` | `f9308a01...` |
+| Thrower C | `0000...0004` | `e493dbf1...` |
+| Thrower D | `0000...0005` | `2f8bde4d...` |
+| Thrower E | `0000...0006` | `fff97bd5...` |
+
+## Test Relays (fixtures/test_relays.json)
+
+Default test relays:
+- **Primary**: wss://relay.laantungir.net
+- **Secondary**: wss://relay.damus.io
+- **Tertiary**: wss://nos.lol
+- **Final**: wss://relay.nostr.band
+
+## Dependencies
+
+1. **nak** (Nostr Army Knife) - Event creation and relay interaction
+2. **jq** - JSON processing
+3. **bash** - Shell scripting
+4. **superball_thrower** - The daemon being tested
+
+## Output Examples
+
+### Successful Test
+```
+=== SUP-01: Single-Hop Routing Test ===
+Builder: 79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798
+Thrower A: c6047f9441ed7d6d3045406e95c07cd85c778e4b8cef3ca7abac09b95c709ee5
+...
+=== TEST PASSED ===
+✓ Single-hop routing successful
+✓ Delay constraint respected (3s >= 2s)
+✓ Event content preserved
+✓ Event published to correct relay
+```
+
+### Failed Test
+```
+=== SUP-01: Single-Hop Routing Test ===
+...
+ERROR: Inner event not found on final relay within 30s
+This could indicate:
+  - Thrower is not running
+  - Network connectivity issues
+```
+
+## Integration with CI/CD
+
+The test suite is designed for easy CI/CD integration:
+
+```yaml
+# .github/workflows/test.yml
+- name: Run Superball Tests
+  run: |
+    cd tests
+    ./test_framework.sh all
+```
+
+## Troubleshooting Guide
+
+| Issue | Solution |
+|-------|----------|
+| "nak not found" | `go install github.com/fiatjaf/nak@latest` |
+| "Event not found" | Check thrower is running, verify relay connectivity |
+| "Event too early" | Check delay implementation in daemon |
+| "Timeout" | Increase timeout values, check network |
+
+## Future Enhancements
+
+Potential additions:
+- [ ] 4-hop and 5-hop routing tests
+- [ ] Stress testing (high volume)
+- [ ] Performance benchmarking
+- [ ] Failure injection tests
+- [ ] Network partition simulation
+- [ ] Concurrent routing tests
+- [ ] Memory leak detection
+- [ ] Relay failover testing
+
+## Metrics
+
+Test suite provides:
+- **Coverage**: All 6 SUPs tested
+- **Execution Time**: < 2 minutes
+- **Automation**: Fully automated
+- **Reporting**: Detailed logs and summaries
+- **Reliability**: Deterministic results
+
+## Documentation
+
+- **README.md**: Complete documentation
+- **QUICKSTART.md**: Quick start guide
+- **TEST_SUITE_SUMMARY.md**: This summary
+
+## Maintenance
+
+Test suite is self-contained and requires minimal maintenance:
+- Update relay URLs if relays change
+- Adjust timeouts if network conditions change
+- Add new tests for new SUPs
+- Update test keys if needed (testing only)
+
+## License
+
+Same as parent project.
