Security: - Add HTTP Basic/Digest authentication middleware (enable via MINING_API_AUTH env) - Fix WebSocket origin check with proper URL parsing - Add max limit (10000) to remote log lines request - Improve CLI args validation with stricter patterns Networking: - Fix WebSocket double-close with sync.Once in PeerConnection - Add 10s dial timeout for WebSocket connections - Reset write deadline after failed sends - Fix handler race in Transport.OnMessage with RWMutex - Make EventHub.Stop() idempotent, buffer channels to prevent goroutine leaks Code Simplification: - Extract AtomicWriteFile helper to reduce duplication across 4 files - Remove redundant MinerTypeRegistry, use MinerFactory instead - Register simulated miner in MinerFactory - Remove dead portToString() code from manager.go Documentation: - Add Advanced API Authentication section to FUTURE_IDEAS.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
