nx_vcodec_inloop_gate.nx

nx_vcodec_inloop_gate.nx -- proves IN-LOOP deblocking helps COMPRESSION: at a high QP the reconstructed reference frame has blocking artifacts; if both encoder and decoder deblock that reference before predicting the next frame (identically, so they stay in sync), the cleaner reference predicts better -> smaller residual -> a smaller next- frame stream. Applied AROUND the codec (the deblock organ carries a syscall import; keeping it outside nx_vcodec preserves the wasm-clean codec path). Measures the same inter frame coded from a RAW vs a DEBLOCKED reference.
