about

nx_vcodec_golomb_gate.nx -- KAT for the vcv-10 exp-Golomb MV-delta verbs (F608 MVD bundle). Proves: (1) vc_gput -> vc_gget round-trips exact over the signed sweep (qpel MV deltas live inside); (2) emitted bit-length == the probe's gbits() cost mirror (2*blen(zze+1)-1) for EVERY value -- the RD costing and the wire can never drift; (3) packed-stream decode in order with exact end position. Rides nx_gate_verdict (migrate-on-touch law D001). license_tier: ORIGINAL expect_exit: 0
