Implemented the 'peer ping' command by establishing an IPC mechanism between the CLI and the running 'node serve' process.
- Added 'ControlService' in 'pkg/node' exposing RPC methods over a Unix socket.
- Implemented 'MessageDispatcher' to route P2P messages to 'Controller' (responses) or 'Worker' (requests).
- Updated 'node serve' to start the IPC server and use the dispatcher.
- Updated 'peer ping' to use the IPC client to request pings from the running node.
- Fixed broken 'pkg/node/dispatcher.go' file.
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

Networking/Protocol fixes:
- Add HTTP server timeouts (Read/Write/Idle/ReadHeader) in service.go
- Fix CORS address parsing to use net.SplitHostPort safely
- Add request body size limit middleware (1MB max)
- Enforce MaxConns limit in WebSocket upgrade handler
- Fix WebSocket origin validation to only allow localhost
- Add read/write deadlines to WebSocket connections
Memory leak fixes:
- Add sync.Once to Manager.Stop() to prevent double-close panic
- Fix controller pending map leak by closing response channel
- Add memory reallocation for hashrate history slices when oversized
- Fix LogBuffer to truncate long lines and force reallocation on trim
- Add process wait timeout to prevent goroutine leaks on zombie processes
- Drain HTTP response body on copy error to allow connection reuse
Segfault/panic prevention:
- Add nil check in GetTotalHashrate for stats pointer
- Fix hashrate history slice reallocation to prevent capacity bloat

Implement secure peer-to-peer communication between Mining CLI instances
for remote control of mining rigs. Uses Borg library for encryption
(SMSG, STMF, TIM) and Poindexter for KD-tree based peer selection.
Features:
- Node identity management with X25519 keypairs
- Peer registry with multi-factor optimization (ping/hops/geo/score)
- WebSocket transport with SMSG encryption
- Controller/Worker architecture for remote operations
- TIM/STIM encrypted bundles for profile/miner deployment
- CLI commands: node, peer, remote
- REST API endpoints for node/peer/remote operations
- Docker support for P2P testing with multiple nodes
