about

nx_uxf_decode_test.nx -- the TOLERANT-READER (house-of-cards) KAT. Proves: (T1) decode reads ALL fields incl one the reader doesn't "know"; (T2) round-trip encode->decode->re-encode reproduces the IDENTICAL CID (unknown field preserved); (T3) the profiled multicodec CID round-trips too; (T4 neg-control) DROPPING a field changes the CID (so preservation is load-bearing -- new data WOULD break an intolerant reader). expect_exit: 0 license_tier: ORIGINAL
