+# CLAUDE.md
+
+## Project
+
+`go-p2p` is the P2P networking layer for the Lethean network. Module path: `forge.lthn.ai/core/go-p2p`
+
+## Commands
+
+```bash
+go test ./...                    # Run all tests
+go test -run TestName ./...      # Single test
+go test -cover ./node            # Coverage for node package
+go test -bench . ./...           # Benchmarks
+go vet ./...                     # Static analysis
+```
+
+## Architecture
+
+Three packages:
+
+### node/ — P2P Mesh
+- **identity.go**: Ed25519 keypair, PEM serialisation, X25519 ECDH, challenge-response auth
+- **transport.go**: Encrypted WebSocket (gorilla/websocket + Borg SMSG), handshake, keepalive, dedup, rate limiting
+- **peer.go**: Registry with KD-tree scoring (Poindexter), persistence, auth modes (open/allowlist)
+- **message.go**: 15 typed protocol messages (handshake, ping, stats, miner, deploy, logs, error)
+- **protocol.go**: Response handler with validation and typed parsing
+- **worker.go**: Command handlers (ping, stats, miner start/stop, deploy, logs)
+- **controller.go**: Remote node operations (connect, command, disconnect)
+- **dispatcher.go**: UEPS packet routing skeleton (STUB — needs implementation)
+- **bundle.go**: TIM encryption, tarball extraction with Zip Slip defence
+
+### ueps/ — Wire Protocol (RFC-021)
+- **packet.go**: PacketBuilder with TLV encoding and HMAC-SHA256 signing
+- **reader.go**: Stream parser with integrity verification
+- TLV tags: 0x01-0x05 (header), 0x06 (HMAC), 0xFF (payload marker)
+- Header: Version (0x09), CurrentLayer, TargetLayer, IntentID, ThreatScore
+
+### logging/ — Structured Logger
+- Levelled (DEBUG/INFO/WARN/ERROR) with key-value pairs and component scoping
+
+## Dependencies
+
+- `github.com/Snider/Borg` — STMF crypto, SMSG encryption, TIM
+- `github.com/Snider/Poindexter` — KD-tree for peer selection
+- `github.com/Snider/Enchantrix` — Secure environment (via Borg)
+- `github.com/gorilla/websocket` — WebSocket transport
+- `github.com/google/uuid` — Peer/message IDs
+- Lethean codenames: Borg (Secure/Blob), Poindexter (Secure/Pointer), Enchantrix (Secure/Environment)
+
+## Coding Standards
+
+- UK English (colour, organisation, centre)
+- All types annotated
+- Tests use `testify` assert/require
+- Licence: EUPL-1.2
+- Security-first: HMAC on all wire traffic, challenge-response auth, Zip Slip defence, rate limiting
+
+## Test Conventions
+
+Use table-driven subtests with `t.Run()`.
+
+## Key Interfaces
+
+```go
+// MinerManager — decoupled miner control (worker.go)
+type MinerManager interface {
+    StartMiner(config map[string]any) error
+    StopMiner(id string) error
+    GetStats() map[string]any
+    GetLogs(id string, lines int) ([]string, error)
+}
+
+// ProfileManager — deployment profiles (worker.go)
+type ProfileManager interface {
+    ApplyProfile(name string, data []byte) error
+}
+```

+# Findings
+
+## Code Quality
+
+- **76 tests in node/, all pass** — but only 42% statement coverage
+- **logging/ fully tested** (12 tests, 100% coverage)
+- **UEPS has ZERO tests** — 262 lines of crypto wire protocol completely untested
+- **`go vet` clean** — no static analysis warnings
+- **Zero TODOs/FIXMEs** in codebase
+
+## Security Posture (Strong)
+
+- X25519 ECDH key exchange with Borg STMF
+- Challenge-response authentication (HMAC-SHA256)
+- TLS 1.2+ with hardened cipher suites
+- Message deduplication (5-min TTL, prevents amplification)
+- Per-peer rate limiting (100 burst, 50 msg/sec)
+- Tarball extraction: Zip Slip defence, 100 MB per-file limit, symlink/hardlink rejection
+- Peer auth modes: open or public-key allowlist
+
+## Architecture Strengths
+
+- Clean separation: identity / transport / peers / protocol / worker / controller
+- KD-tree peer selection via Poindexter: [PingMS × 1.0, Hops × 0.7, GeoKM × 0.2, (100-Score) × 1.2]
+- Debounced persistence (5s coalesce window for peer registry)
+- Buffer pool for JSON encoding (reduces GC pressure)
+- Decoupled MinerManager/ProfileManager interfaces
+
+## Critical Test Gaps
+
+| File | Lines | Tests | Coverage |
+|------|-------|-------|----------|
+| identity.go | 290 | 5 tests | Good |
+| peer.go | 708 | 19 tests | Good |
+| message.go | 237 | 8 tests | Good |
+| worker.go | 402 | 10 tests | Good |
+| bundle.go | 355 | 9 tests | Good |
+| protocol.go | 88 | 5 tests | Good |
+| **transport.go** | **934** | **0 tests** | **NONE** |
+| **controller.go** | **327** | **0 tests** | **NONE** |
+| **dispatcher.go** | **39** | **stub** | **N/A** |
+| **ueps/packet.go** | **124** | **0 tests** | **NONE** |
+| **ueps/reader.go** | **138** | **0 tests** | **NONE** |
+
+## Known Issues
+
+1. **dispatcher.go is a stub** — Contains commented-out UEPS routing code. Threat circuit breaker and intent routing not implemented.
+2. **UEPS 0xFF payload length ambiguous** — Relies on external TCP framing, not self-delimiting. Comments note this but no solution implemented.
+3. **Potential race in controller.go** — `transport.OnMessage(c.handleResponse)` called during init; if message arrives before pending map ready, could theoretically panic (unlikely in practice).
+4. **No resource cleanup on some error paths** — transport.handleWSUpgrade doesn't clean up on handshake timeout; transport.Connect doesn't clean up temp connection on error.
+5. **Threat score semantics undefined** — Referenced in dispatcher stub and UEPS header but no scoring/routing logic exists.

+# TODO
+
+## High Priority — Test Coverage (currently 42%)
+
+- [ ] **UEPS packet tests** — Zero tests for wire protocol. Need: builder round-trip, HMAC verification, malformed packet rejection, empty payload, oversized payload, max ThreatScore boundary.
+- [ ] **Transport tests** — 934 lines untested. Need: WebSocket handshake (accept + reject), SMSG encryption round-trip, connection lifecycle, keepalive timeout, rate limiting, deduplication, protocol version mismatch.
+- [ ] **Controller tests** — 327 lines untested. Need: request-response correlation, timeout handling, auto-connect, concurrent requests, GetAllStats parallel execution.
+
+## Medium Priority — Coverage Target 70%+
+
+- [ ] **Dispatcher implementation** — Currently a commented-out stub. Implement UEPS packet routing with threat circuit breaker (drop ThreatScore > 50000) and intent-based dispatch.
+- [ ] **Integration test** — Full node-to-node handshake over localhost WebSocket with encrypted message exchange.
+- [ ] **Benchmarks** — Peer scoring (KD-tree), UEPS marshal/unmarshal, identity key generation, message serialisation.
+- [ ] **bufpool.go tests** — Buffer reuse verification, large buffer handling.
+
+## Low Priority
+
+- [ ] **Logging package tests** — Simple but should have coverage for completeness.
+- [ ] **Peer discovery** — Currently manual peer registration. Add mDNS or DHT-based discovery.
+- [ ] **Connection pooling** — Transport creates fresh connections; add pool for controller reuse.
+- [ ] **Error recovery tests** — Handshake timeouts, protocol version mismatch, allowlist rejection, connection drop/reconnect.
