nx_cdc_gate.nx

nx_cdc_gate.nx -- IN-PROCESS gate over nx_cdc_lib (/compare/dataio DI5 cp_cdc_gear): content-defined chunking must (1) partition the input within its declared bounds, (2) be deterministic, (3) survive an INSERTION with almost every chunk digest intact while the fixed-size CONTROL loses almost every chunk after the edit -- that pair is the whole claim, and neither half alone proves it -- and (4) refuse parameters that are not a chunking. The corpus is a pseudo-random 1 MiB buffer from a seeded xorshift generator (no file, no clock), the parameters are the ones nx_content_put derives from its wire chunk (48,402 -> max 48402, avg 24201, min 6050). exit: 0 GREEN / 1 RED (gv_verdict law).
