nx_wolf_walk_gate.nx

nx_wolf_walk_gate.nx -- the ANIMAL moves: the bestiary wolf WALKS on a quadruped FK rig with a real diagonal gait, rendered on the production shader, shipped as sovereign video. Completes the operator's species span (person waves -> beastman looks around -> wolf walks). T1 valid APNG (acTL num_frames == N) T2 MOTION present (frame checksums differ) T3 FOUR-BEAT WALK: the four legs occupy FOUR DISTINCT phases, not two coincident diagonal pairs. Corrected 2026-08-25 -- this tooth used to assert FL==HR, which is the signature of a TROT, and so it enforced a trotting wolf under the name walk. A tooth that passes for both gaits is not testing the gait; this one fails for a trot by construction. T4 wolf on screen (foreground coverage >= 5%) Writes knowledge/synth_wolfwalk.png (APNG) + knowledge/synth_wolfwalk_f0.png (still). license_tier: ORIGINAL expect_exit: 0
