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

Security fixes:
- Remove hardcoded wallet address from CLI defaults (start.go, serve.go)
Pool and wallet are now required flags or must be provided explicitly
- Change file permissions from 0644 to 0600 for sensitive config files
Affects: xmrig config, profiles, settings, config cache
- Fix path traversal in untar() - now returns error instead of silently skipping
Concurrency fix:
- Fix race condition in GetStats() - was using RLock while writing m.FullStats
Changed to Lock/Unlock in both xmrig_stats.go and ttminer_stats.go
