Covers ASHRAE RP-1485 scenarios from HAValidation.py as C++ Catch2 tests so they run in CI instead of only during Python doc builds: - [ashrae_a61]: saturated air T=-60..0°C (ice regime, R=1) - [ashrae_a62]: saturated air T=0..90°C (liquid regime, R=1) - [ashrae_a8/a9]: hot humid air T=200/320°C across multiple pressures - [humid_air_physics]: T_dp <= T_wb <= T_db ordering, W/R invariants - [humid_air_roundtrip]: W, H, T_dp, T_wb round-trips - [humid_air_aux]: f_factor, p_ws, beta_H, kT, vbar_ws, virial checks Also documents two current behaviors as known baselines: - W_sat > 1 kg/kg is physically correct above ~60 degC (not a bug) - beta_H returns inf below 273.16 K (no liquid water) Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
