about
nx_room_interframe.nx -- the FIX for the measured 9fps (nx_room_bw_measure: full-frame JPEG saturates
the uplink; inter-frame coding -> 31fps). Sovereign inter-frame (P-frame) codec CORE, ready to wire
onto the live media plane: encode(prev,cur) -> per-block {SKIP if unchanged | quantized WHT residual},
decode(prev,stream) -> cur'. Skip blocks copy prev EXACTLY (zero bytes); changed blocks carry only the
residual. 4x4 Walsh-Hadamard (self-inverse up to /16) + rounding quant. Proves the mechanism is real +
byte-budget; the client capture-diff + the daemon relay of residual packets + deploy = the wire-in.
GREEN = reconstruct within quant error, skip-blocks bit-exact, bandwidth strictly smaller.
