v0.0.38: FC-P4 complete — session versioning, wire envelope, auto-backup
FC-P4-T1: Session State Versioning
- RatchetState serialize/deserialize with [MAGIC:0xFC][VERSION:1][bincode]
- Legacy (raw bincode) still loads — backward compatible
- Client + WASM both use versioned format
- 2 new tests: roundtrip + legacy compat
FC-P4-T2: WireMessage Versioning Envelope
- Format: [WZ magic][version:u8][length:u32 BE][bincode payload]
- Server + client + WASM accept both envelope and legacy on receive
- Client still sends raw bincode (server handles both)
- Future version → "update required" error instead of crash
- 3 new tests: roundtrip, legacy compat, future version rejection
FC-P4-T3: Periodic Auto-Backup
- Every 5 minutes, encrypts sessions+contacts+sender_keys to ~/.warzone/backups/
- HKDF-derived key from seed, ChaCha20-Poly1305 AEAD
- Atomic writes (temp file + rename), rotates to keep last 3
- /backup command for manual trigger
127 tests passing (was 122)

Scaffold Rust workspace: warzone-protocol, server, client, mule
4 crates, all compile. 16/17 tests pass.
warzone-protocol (core crypto):
- Seed-based identity (Ed25519 + X25519 from 32-byte seed via HKDF)
- BIP39 mnemonic encode/decode (24 words)
- Fingerprint type (SHA-256 truncated, displayed as xxxx:xxxx:xxxx:xxxx)
- ChaCha20-Poly1305 AEAD encrypt/decrypt with random nonce
- HKDF-SHA256 key derivation
- Pre-key bundle generation with Ed25519 signatures
- X3DH key exchange (simplified, needs X25519 identity key in bundle)
- Double Ratchet: full implementation with DH ratchet, chain ratchet,
out-of-order message handling via skipped keys cache
- Message format (WarzoneMessage envelope + RatchetHeader)
- Session type with ratchet state
- Storage trait definitions (PreKeyStore, SessionStore, MessageQueue)
warzone-server (axum):
- sled database (keys, messages, one-time pre-keys)
- Routes: /v1/health, /v1/keys/register, /v1/keys/{fp},
/v1/messages/send, /v1/messages/poll/{fp}, /v1/messages/{id}/ack
warzone-client (CLI):
- `warzone init` — generate seed, show mnemonic, save to ~/.warzone/
- `warzone recover <words>` — restore from mnemonic
- `warzone info` — show fingerprint and keys
- Seed storage at ~/.warzone/identity.seed (600 perms)
- Stubs for send, recv, chat commands
warzone-mule: Phase 4 placeholder
Known issue: X3DH test fails (initiate/respond use different DH ops
due to missing X25519 identity key in bundle). Fix in next step.
