+
+**Bone hierarchy fixed**
+
+**Fixed:**
+1. `MCH-torso.parent` — now parented to `root`
+2. 8 other MCH- parent bones — now parented to `root`:
+   - `MCH-hand_ik.parent.L` and `.R`
+   - `MCH-upper_arm_ik_target.parent.L` and `.R`
+   - `MCH-foot_ik.parent.L` and `.R`
+   - `MCH-thigh_ik_target.parent.L` and `.R`
+
+**Verified:**
+- `DEF-spine` is child of `root`
+- `MCH-eyes_parent` is child of `root`
+- Root bone now has 15 direct children (properly structured)
+
+The bone hierarchy is now properly organized with all critical mechanism bones parented to the root. The rig should be ready for the next steps.
+
+What would you like me to do next?

+
+Good. Now, let's fix those bad drivers. I removed the layers 23 driver. We have to be sure that we don't break the IK hands as described in that context document.
