Per outer step the driver pushes leakoff into the reservoir grid (sign by mode), advances backward-Euler Darcy, samples ΔPp = p − p_init across the footprint, and feeds applyDepletionToFracGeometry to recompute σ_min_eff (poroelastic + thermoelastic). Flowback ⇒ ΔPp<0 ⇒ σ_min_eff<σ_min,init; pumping flips both signs.
