about

nx_dgram_media_gate.nx -- proves the SOVEREIGN datagram media wire (nx_dgram_media, task #15 R1) under the conditions UDP actually delivers: LOSS, REORDER, DUPLICATION -- the in-process netem-class proof, fully sovereign. Frames must reassemble BIT-EXACT; gaps must surface as NACKs; the NACK wire must round- trip; retransmits must complete the set with NO double-delivery; hostile packets must be refused without corrupting state. Deterministic PRNG (seeded LCG -- reproducible, no Math.random). 0=GREEN / 1=RED.
