+# 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
+[Unit]
+Description=Superball Thrower Daemon (C Implementation)
+Documentation=https://git.laantungir.net/laantungir/super_ball_thrower
+After=network-online.target
+Wants=network-online.target
+
+[Service]
+Type=simple
+User=superball-thrower
+Group=superball-thrower
+WorkingDirectory=/usr/local/bin/super_ball_thrower
+ExecStart=/usr/local/bin/super_ball_thrower/superball_thrower /usr/local/bin/super_ball_thrower/config.json
+Restart=always
+RestartSec=10
+StandardOutput=journal
+StandardError=journal
+SyslogIdentifier=superball-thrower
+
+# Security settings

+PrivateTmp=true
+ProtectSystem=strict
+ProtectHome=true
+ReadWritePaths=/var/log/superball-thrower /usr/local/bin/super_ball_thrower

+
+# Resource limits
+LimitNOFILE=65536
+LimitNPROC=4096
+
+[Install]
+WantedBy=multi-user.target
+```
+
+### 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
+#!/bin/bash
+# Deployment script for Superball Thrower to lt server
+# This script builds the binary locally and deploys it to the server
+
+set -e
+
+echo "=== Superball Thrower Deployment Script ==="

+# Colors for output
+RED='\033[0;31m'
+GREEN='\033[0;32m'
+YELLOW='\033[1;33m'
+NC='\033[0m' # No Color
+
+# Step 1: Clean previous build
+echo -e "${YELLOW}[1/6] Cleaning previous build...${NC}"
+make clean || true
+
+# Step 2: Build the project
+echo -e "${YELLOW}[2/6] Building superball_thrower...${NC}"

+    echo -e "${RED}Error: Build failed - binary not found${NC}"
+    exit 1
+fi
+
+echo -e "${GREEN}Build successful!${NC}"
+
+# Step 3: Stop the service on the server
+echo -e "${YELLOW}[3/6] Stopping service on server...${NC}"
+ssh $SERVER "sudo systemctl stop $SERVICE_NAME" || echo "Service not running or doesn't exist yet"
+
+# Step 4: Deploy binary to server
+echo -e "${YELLOW}[4/6] Deploying binary to server...${NC}"
+scp $BINARY_NAME $SERVER:/tmp/$BINARY_NAME
+
+# Step 5: Move binary to final location with proper permissions
+echo -e "${YELLOW}[5/6] Installing binary...${NC}"
+ssh $SERVER "sudo mv /tmp/$BINARY_NAME $DEPLOY_DIR/$BINARY_NAME && \
+             sudo chown superball-thrower:superball-thrower $DEPLOY_DIR/$BINARY_NAME && \
+             sudo chmod 755 $DEPLOY_DIR/$BINARY_NAME"
+
+# Step 6: Restart the service
+echo -e "${YELLOW}[6/6] Starting service...${NC}"
+ssh $SERVER "sudo systemctl start $SERVICE_NAME"
+
+# Wait a moment for service to start
+sleep 2
+
+# Check service status
+echo ""
+echo -e "${YELLOW}Service Status:${NC}"
+ssh $SERVER "sudo systemctl status $SERVICE_NAME --no-pager" || true
+
+echo ""
+echo -e "${GREEN}=== Deployment Complete ===${NC}"
+echo ""
+echo "Useful commands:"
+echo "  View logs:    ssh $SERVER 'sudo journalctl -u $SERVICE_NAME -f'"
+echo "  Check status: ssh $SERVER 'sudo systemctl status $SERVICE_NAME'"
+echo "  Restart:      ssh $SERVER 'sudo systemctl restart $SERVICE_NAME'"
+echo "  Stop:         ssh $SERVER 'sudo systemctl stop $SERVICE_NAME'"
+```
+
+## 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": {
+    "privateKey": "0000000000000000000000000000000000000000000000000000000000000002",

+```
+
+### 3. Multi-Hop Test (3 Throwers)
+
+**Setup Thrower A, B, C:**
+```bash
+# Terminal 1 - Thrower A
+cd ..
+./superball_thrower config_test_a.json
+
+# Terminal 2 - Thrower B (create config first)

+
+**Run Tests:**
+```bash
+# Terminal 4
+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

+# 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
+```

+
+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)

+
+**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.
+
+## Interpreting Results
+
+### Success Output
+
+```
+=== Superball Protocol Test Suite ===
+Starting at Mon Dec 10 14:00:00 UTC 2025
+
+Running: test_single_hop
+✓ PASSED: test_single_hop (12s)
+
+Running: test_multi_hop
+✓ PASSED: test_multi_hop (38s)
+
+...
+
+=== Test Summary ===
+Passed:  7
+Failed:  0
+Skipped: 0
+Total:   7
+```
+
+### 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.
+
