nx_fec_stripe.nx

nx_fec_stripe.nx -- FEC-COMPLEMENTARY striping: the exceed beyond plain multi-path duplication. Combines nx_fec_xor (parity repair) with nx_pathstripe (multi-path): source packets travel on one path, FEC REPAIR symbols on a complementary path. A source packet lost on its path -- with NO duplicate anywhere -- is reconstructed by the parity on a surviving path. This recovers CORRELATED / all-path loss (which plain seq-dedup striping cannot: it needs the packet to survive on >=1 path) AND does so at SUB-100% bandwidth overhead (repairs/source < 1), vs the 100% overhead of 1+1 duplication. Pure-XOR -> integer-only, sovereign. license_tier: ORIGINAL
