Johnathan Corgan	4ff1762434	Add MTU fields to lookup packets for path MTU discovery ... Add min_mtu (u16) to LookupRequest and path_mtu (u16) to LookupResponse, enabling the discovery system to report transport MTU capability along the lookup path. LookupRequest carries min_mtu (origin's minimum MTU requirement, default 0 = no requirement). LookupResponse carries path_mtu (initialized to u16::MAX by the target, reduced by transit nodes via min(path_mtu, outgoing_link_mtu) on the reverse path). path_mtu is a transit annotation like SessionDatagram.path_mtu and is NOT included in the proof signature. The originator stores the discovered path_mtu in CacheEntry alongside cached coordinates. Wire format: +2 bytes each for LookupRequest and LookupResponse.	2026-02-22 21:52:08 +00:00
Johnathan Corgan	930f139787	Split cache.rs and config.rs into directory modules, create utils/ ... Module reorganization for three large single-file modules: cache.rs (792 lines) split into cache/ directory: - cache/mod.rs: CacheError, CacheStats, re-exports - cache/entry.rs: CacheEntry with TTL/LRU tracking - cache/coord_cache.rs: CoordCache (address-to-coordinate mappings) - cache/route_cache.rs: RouteCache + CachedCoords (discovery routes) - Added 22 new tests filling coverage gaps across all submodules config.rs (1318 lines) split into config/ directory: - config/mod.rs: ConfigError, IdentityConfig, Config struct with file loading/merge logic, all 24 integration tests - config/node.rs: NodeConfig + 9 subsection structs (Limits, RateLimit, Retry, Cache, Discovery, Tree, Bloom, Session, Buffers) - config/transport.rs: TransportInstances<T>, TransportsConfig, UdpConfig - config/peer.rs: ConnectPolicy, PeerAddress, PeerConfig DnsConfig and TunConfig moved to upper/config.rs to co-locate with the upper layer components they configure (TUN interface, DNS responder). index.rs moved to utils/index.rs as cross-cutting infrastructure that serves both node and peer layers.	2026-02-15 17:56:32 +00:00
