Restoration lever 2: reduce the pathological drive
Lever S2 REDUCES the chronic forcing h_path that pushes the state toward the disease basin -- either by cutting intake drive (MC4R melanocortin tone, GHRL hunger axis) or by raising thermogenic disposal (UCP1 furnace, ADRB3 command) to lower the net energy surplus. Structural direction [F]; clinical magnitude [O].
The analog of analgesic L1 (reduce the inward current). Lowering the forcing is what returns a DRIFTED setpoint (the obesity claim) and relieves a loop that has not yet crossed. Reads [V]; lever placement [F]; clinical magnitude [O].
What S2 does to the law
S2 lowers |h_path| in §15's law without touching the barrier; for a sub-spinodal (drifted) loop this moves the defended state back toward healthy. Notably the thermogenic nodes connect this lever straight to the endotherm furnace of Q1 -- raising disposal is the same UCP1/ADRB3 pair, used to shed surplus rather than defend temperature.

The thermogenic-disposal direction is [F] structural; γ is not a metabolic rate. No claim is made that any agent achieves a given expenditure or weight change.
