nx_uxf_negotiate_gate.nx -- the D001 MIGRATION of nx_uxf_negotiate_test onto nx_gate_verdict (2026-09-06). The headline case is the operator's own: MKV carrying H.264 and AAC, served to Chrome, must resolve to REMUX and not TRANSCODE -- Chrome cannot read the MKV container but decodes both codecs fine, so the correct answer is a LOSSLESS REWRAP. Getting this wrong in the safe-looking direction (transcode everything) is silent quality loss, which is why the plan is asserted per case rather than in aggregate. ALL FIVE ORIGINAL TEETH PRESERVED IN ORDER AND PREDICATE, PLUS TWO THE ORIGINAL LACKED. The original PRINTED whether the capability rows loaded but never asserted it, so a failure to read the TSV would have been judged only indirectly by the outcomes. T0a and T0b now assert the fixture REACHED ITS CONDITION before any outcome is claimed, which is the estate's standing rule for exactly this shape. license_tier: ORIGINAL No hw writes (Rule 26).
