about
nx_vc_fec_gate.nx -- native cross-gate for the RS-FEC engine now IN the video client core
(vc_fec_init/encode/decode, k=8 m=2, caller-provided regions -- the FEC-LIVE prerequisite).
Mirrors the proven nx_room_fec gate honesty on the CORE's implementation:
T1 systematic (first k*S of shards == data) T2 EXHAUSTIVE: every 2-erasure pattern of
C(10,2)=45 recovers a JPEG-like frame byte-exact T3 over-bound: 3 erasures MUST fail (-1)
T4 tamper: a corrupted generator entry MUST break recovery (matrix is load-bearing)
