Issues

• Shared RT60 quick estimate computes air attenuation and discards it, so the top bands never decay from air

• Ray tracer / beam trace: hit normals are used in the wrong space, and worldHitNormal's two branches each fix what the other breaks

• #120's ray-origin epsilon was never added — ART still shoots from the triangle plane

• ART loses ~28% of energy per bounce independent of absorption, so T60 is 2–4× short

• pressureReflectionCoefficient uses the reciprocal impedance branch: rigid walls reflect with R = −1, and R never changes sign with angle
