CAPPER_TORQUE_CTRL
Capper application-torque verification per closure, with plausibility checking and consecutive-failure head fault.
When to use it
Use CAPPER_TORQUE_CTRL when a capping head applies closures against a measured application torque and every closure has to be verified against a window, with a run of failures taken as a head that has lost its clutch setting rather than a run of bad caps.

Supervised control write
CAPPER_TORQUE_CTRL commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.
