Error Handling:
- Fix silent Write() error in WebSocket (events.go)
- Add error context to transport handshake messages
- Check os.MkdirAll error in zip extraction (miner.go)
- Explicitly ignore io.Copy errors on drain with comments
- Add retry logic (2 attempts) for transient stats collection failures
Resource Lifecycle:
- Add shutdown mechanism to DigestAuth goroutine
- Call Service.Stop() on context cancellation
- Add NodeService transport cleanup to Service.Stop()
- Fix WriteStdin goroutine leak on timeout with non-blocking send
API Design:
- Add profile validation (name, miner type required)
- Return 404 instead of 500 for missing profile PUT
- Make DELETE profile idempotent (return success if not found)
- Standardize error responses in node_service.go handlers
Observability:
- Add logging for P2P GetAllStats failures
- Add request ID correlation helper for handler logs
- Add logging for miner process exits (xmrig_start.go)
- Rate limit debug logs in transport hot path (1 in 100)
- Add metrics infrastructure with /metrics endpoint

WebSocket Real-Time Events:
- Add EventHub for broadcasting miner events to connected clients
- New event types: miner.starting/started/stopping/stopped/stats/error
- WebSocket endpoint at /ws/events with auto-reconnect support
- Angular WebSocketService with RxJS event streams and fallback to polling
Simulation Mode (miner-ctrl simulate):
- SimulatedMiner generates realistic hashrate data for UI development
- Supports presets: cpu-low, cpu-medium, cpu-high, gpu-ethash, gpu-kawpow
- Features: variance, sine-wave fluctuation, 30s ramp-up, 98% share rate
- XMRig-compatible stats format for full UI compatibility
- NewManagerForSimulation() skips autostart of real miners
Miners Page Redesign:
- Featured cards for installed/recommended miners with gradient styling
- "Installed" (green) and "Recommended" (gold) ribbon badges
- Placeholder cards for 8 planned miners with "Coming Soon" badges
- Algorithm badges, GitHub links, and license info for each miner
- Planned miners: T-Rex, lolMiner, Rigel, BzMiner, SRBMiner, TeamRedMiner, GMiner, NBMiner
Chart Improvements:
- Hybrid data approach: live in-memory data while active, database historical when inactive
- Smoother transitions between data sources
Documentation:
- Updated DEVELOPMENT.md with simulation mode usage
- Updated ARCHITECTURE.md with WebSocket, simulation, and supported miners table
