Test	What it does	Result
test_clamp_empties_primal	A model peaking at -1 leaves the clamped primal empty, so the unshifted dual runs along a ray above 1e6, its negative far below the peak.	✅ pass
test_floor_bounds_model	The floor sits at or below the model everywhere on the simplex, over a hundred pseudorandom sets of one to three cuts.	✅ pass
test_shift_recovers_maximum	Shifting by the model's floor and back bounds four negative-peak models from above within 1e-9 of the closed-form peak, where the unshifted assembly reads over 1e12 below.	✅ pass
test_shift_stays_inert	A model with its floor at or above zero, as every shipped assembly has, is assembled unshifted: a dominating plane pair caps at its peak and both rrdps caps return their pins.	✅ pass
