Vendor files abbreviate for control code. The inspector expands those tokens; the vendor id stays in monospace. At full width, left and right joints of the same part share a matrix: one column per part, one row per side.
SideL / left → Left. R / right → Right. A trailing R after a side is roll, not another right.
JointHip, Knee, Ank, Sh, Elb, Wr, Waist, Head expand to hip, knee, ankle, shoulder, elbow, wrist, waist, head.
AxisP pitch, R roll, Y yaw. So LHipP is Left hip pitch, not a product metric.
GroupsRows are filed under Legs, Arms, Hands, Torso, Head, Base, or Other from those tokens. Fixed attachments stay collapsed; they hold the tree together but do not move.
