Full-stack Go monolith with embedded React frontend for orchestrating rsync-over-SSH file synchronization with Wake-on-LAN support. Features: - JWT auth (HS256) with bcrypt password hashing - CRUD for machines (with WoL config) and sync_pairs - Ed25519 SSH key generation and known_hosts management - WoL magic packet sender + TCP-connect waiter with backoff - Sync engine: rsync subprocess, per-pair job queue, progress parsing - Homebrew cron parser for scheduled syncs - SSE stream for live job status (queued/waking_up/running/success/failed) - React+TS+Vite+Tailwind SPA embedded via embed.FS - Debian packaging with systemd unit, postinst/prerm/postrm Tech stack: - Go 1.22+ (CGO_ENABLED=0, pure SQLite via modernc.org/sqlite) - chi router for HTTP API - TypeScript + React 18 + Tailwind CSS frontend - Cross-compiled to Linux amd64 for Proxmox LXC deployment Tests: wol (MAC parsing, magic packet), syncengine/queue, scheduler/cron
