Prerequisites

Docker (for ISO building)
pnpm (package manager)
Deno v2.x (for daemon development)
QEMU (for testing)

Commands

# Build the full ISO (auto-rebuilds daemon first)
pnpm run build

# Test ISO in QEMU virtual machine
pnpm run test

# Take screenshot of running VM
pnpm run test:screenshot

# Stop the QEMU VM
pnpm run test:stop

# Clean all build artifacts
pnpm run clean

# Daemon development (watch mode)
pnpm run daemon:dev

# Bundle daemon to standalone binary
pnpm run daemon:bundle

# Type-check daemon code
pnpm run daemon:typecheck

🖥️ Management UI

The daemon exposes a management interface at http://localhost:3006 (or the device's IP on port 3006).

Seamless Upgrade — Downloads new daemon binary, replaces, and restarts service
Manual Override — Force immediate upgrade via UI or API
Version Tracking — UI auto-reloads when daemon version changes

🧪 Testing

QEMU Virtual Machine

# Start VM (creates disk, boots ISO)
pnpm run test

# Take screenshots to monitor progress
pnpm run test:screenshot

# Screenshot loop (every 5 seconds)
pnpm run test:screenshot:loop

# Stop VM
pnpm run test:stop

# Clean and restart fresh
pnpm run test:clean && pnpm run test

Serial Console

For debugging without graphics:

socat - UNIX-CONNECT:.nogit/vm/serial.sock
# Login: ecouser / ecouser
# Root: sudo -i

📦 Release Assets

Each release includes:
