Session 39: Protocol traffic flow design document
Add comprehensive design doc for FIPS protocol message flow covering:
- DNS-based identity cache priming (npub.fips format)
- TUN reader processing pipeline
- Crypto session (Noise KK with secp256k1) vs routing session distinction
- Combined establishment model (routing + crypto in single round-trip)
- Noise KK pattern with ChaCha20-Poly1305, AEAD-only authentication
- Route discovery via bloom filters and LookupRequest flooding
- Crossing hellos handling with deterministic tie-breaker (lower npub wins)
Includes reconciliation section tracking alignment with existing design docs
(fips-routing.md terminology updates pending).
