the first issue is that the ‘geo_skin’ node's selection flag is OFF - this will prevent selecting points, you should turn this back on.
when manually adding bones you must only add the bones you want to use as source bones to the From field
and only add bones you want to use as the destination to the To field
eg:
From : “Head_Head_bone/cregion 0”, “L_Arm_clavicle/cregion 0”
To : “Head_Head_bone/cregion 0”, “R_Arm_clavicle/cregion 0”
Note that in this example the head in is both fields - you'll want and bones in the middle to be in both fields
“L_Arm_clavicle/cregion 0” is in the From field
“R_Arm_clavicle/cregion 0” is in the To field
this will take the weights from the Left and send them to the Right.
hope that helps

I'm not sure I understand what you're trying to do…
if you copy to points and scale - each copy will be scaled - in your case smaller than the one before
this means that the distance between the boxes will change
can you do a quick sketch of what you want the final result to look like?

if you are referring to the Construction Plane then you can orient it in any way you'd like

haven't tested your script but it looks like you have a list of all the geo nodes -> alembic_nodes
the object_merge takes paths of operators
so for each node in your alembic_nodes list
get the path
append that path to a string
then set the objpath1 parm to that string…

geometry missing from the file…
one thing that is commonly done in this situation is to create a null at the origin, parent everything to it, then use Uniform Scale on the null.

not sure - if you blend between IK and FK at frame 1 for the left hand you'll see that in FK the bones are in the same position as the right side…
I made a new HDA based on the one in the file and it comes out just fine…so you may have made a change in the rig somewhere
when I use Match Definition to return your rig to it's saved state the IK/FK blend on the Left Arm doesn't seem to work.

you should find the type of node then based on that do something…
so if it's an HDA of type mySpecialCam then do something etc

>>> node = hou.node('/obj/somenode')
>>> print node.type()
<hou.NodeType for Object cam>
>>> print node.type()
<hou.NodeType for Object cam>

it looks like they are being rotated around as you animate
if I turn off all the controls except for the left foot IK control
and then step through the animation from frame 140-160 I can see that the control is rotating but the foot/leg isn't - so they get a different orientation.
I think I can change the controls in a future update so that you'll see this happening.
for now open this file and go into the geo node
copy the SOPs that are there and then paste them into your L_Foot_footroot etc controls
