nx_netquant.nx

nx_netquant.nx -- sovereign BIT-LEVEL quantized + delta player-state codec for adverse networks (the "girl on a bad mobile network plays seamlessly with a boy in Texas" problem). Composes nx_bitio (MSB-first bit writer/reader). 100% nx, no syscalls -> wasm-friendly AND daemon-reusable. NO logic ever leaves for JS -- the host only moves the resulting bytes. Two frame kinds (the keyframe+delta model, like video I/P frames or Quake3/Source snapshots): FULL (keyframe): every field at minimal fixed width -> 88 bits = 11 bytes (raw was 28). Lossless for in-range values (positions are integer voxels; yaw stored mod 360 in 9 bits; pitch +bias in 8). Sent on join / periodic resync. DELTA (vs a baseline): a 10-bit change-mask + zig-zag VARINT for each changed field. Stationary peer -> ~2 bytes; a small walk -> a few bytes. This is the low-bandwidth win that keeps the bad-network player smooth. Fields f[0..9] = x,y,z,yaw,pitch, species,caught,action,anim, flags x,z: signed voxel (bias +131072, 18 bits each => +/-131071 lossless) y: 0..4095 (12 bits) yaw: 0..359 mod 360 (9 bits) pitch: -85..85 (+128, 8 bits) species 3b, caught 7b, action 3b, anim 6b, flags 4b license_tier: ORIGINAL
