about

_f64_tan_gate_authored.nx -- ME1 tan gate: dd kernel (_pe_f64tan) vs the LIVE sovereign bigfloat tan oracle. Pure Nishi end to end. Edges: pole crossings at small k (fl(pi/2) +- ulp, 3pi/2, 5pi/2), anchor seams (j/8 boundaries after reduction), tiny/subnormal, refusal band; plus 320 banded xorshift points over |x| < 2^20. GREEN iff max ULP <= 1. Markers: TNBAD x= exp= got= ulp= / TAN-ULP ... / TAN-GATE verdict=GREEN|RED
