Developer e91308720b feat: identity hashing for ActorAddress hot-path optimization (Cycle 20) ... Replace SipHash with identity hasher on all hot-path HashMaps keyed by ActorAddress. Since addresses are crypto-random, the first 8 bytes serve as an excellent hash directly. Microbenchmarks show 1.9-4.6x lookup speedup depending on map size. - Custom Hash impl for ActorAddress (8-byte write_u64 instead of 32) - AddrHasher/AddrBuildHasher identity hasher in delivery.rs - AddrMap<V>/AddrSet type aliases used in 7 HashMap sites - Stop-requests is_empty() short-circuit in tick_all inner loop - 3 new behavioral tests, component microbenchmarks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>		2026-02-12 18:01:30 +00:00
