+## DOSE-RESPONSE POINT (2026-07-19, λ=2.0, `results_lambda2.json`)
+Monotone: λ=0.5 → −5.9% blob gauge at ~0% common cost; **λ=2.0 → −8.4% at
++0.9% common cost** (now past the 0.5% P2 bound). The coupling-strength
+trade surface is real and mapped at two points; λ≈1 interpolation and
+pure-band-phase training are the open refinements. (Ops note: this arm
+reused the s0 results filename on-pod — the shipped s0 file is canonical;
+the config's lambda field disambiguates.)
