(Not clued on the mechanics)
Wouldn't it be possible, for a long-term golem/construct, to flavour it as "Sponsored Magic"? Spells are the various manoeuvres the construct can use, debt becomes "damage" or "energy drain" on the construct's supply, and the compels resulting from debt can be reflavoured as the construct misbehaving/leaking magic/shutting down?
Yes, for the most part.
It gets tricky if someone wants to attack your construct directly but this method is basically what Haru suggested. You just reflavour your spell casting.
So instead of saying "I blast him with fire. Weapon 4 attack"
You say, "my gollum breathes fire on him". Weapon 4 attack.
You still target with discipline because it's using up all your concentration to control it.
This method has a down-side which is reflected by the wizards blind spot.
Blocks on movement might prevent ranged attacks if your construct can change zones etc...
The sponsored debt and compels part is interesting. Or you could reflect this with fallout too.
For a Construct's stress (if you want to do it this way), maybe you could say physical attacks do mental damage - which prevents you from controlling it eventually. Or maybe the physical damage gets transferred to yOu. lthough, part of the advantage of having a construct is not having to go in and get hurt.
You could take a toughness power that only applies to attacks on the construct. So the. You could 'virtually' go into a situation and be super tough through your construct.
