Apply .BVH To Rigged Creature

I have a fantasy-style creature that’s already been autorigged in Blender, but the skeleton needs a few small tweaks before motion can flow cleanly through it. Alongside the model I’ll supply a single .bvh mocap file. What I need is for you to adjust the rig where necessary—nothing major, just the usual joint re-alignment or weight touch-ups—and then retarget and bake the motion so the animation runs without foot sliding, scale drift, or pop-through on extreme poses. No need for perfection.

You’ll be working natively in Blender, so please be comfortable with its retargeting add-ons, Action Editor, and NLA tracks. Once the motion is locked in, send back a clean .blend that plays the animation from frame 1, plus an fbx export with the action baked into the armature for easy import elsewhere. Also explain what was done and how, but very briefly.
