v1.9 trial: display-only slope ×1.2667 about 70°F (40°F in v1.8 displays as 32°F). The 70°F initial KE and all physics are unchanged. This is a calibration hypothesis, not a guaranteed plateau. Temperature is inferred from mean liquid KE using a reference calibration; no temperature is clamped at freezing. Heat enters/leaves as molecular kinetic energy. The 32°F reference is user-set, not an independently predicted freezing point.

KE = ½(vx² + vy²) in simulation units. Thresholds use the incident molecule’s total KE. Melting additionally requires KE ≥ latent energy. Latent energy is counted for LIQUID molecules relative to the ice lattice. Event-level energy audits track numerical conservation. Capture probabilities are evaluated for the selected surface site; low-energy impacts can still bounce. This is an illustrative 2D model, not molecular dynamics.
