Four AI models render the same reflection prompt in a 2x2 grid

2x2 grid,1:1 AI picks stunning different subjects: Π           = reflecting plane: point q, unit normal m  R(x)        = x − 2((x−q)·m) m            (reflection across Π) reflected image = scene imaged by the VIRTUAL camera R(C) ; every real feature f has twin R(f)  RENDERED   • reflection is a BIJECTION of the scene across Π ; occlusion order reverses   • points on Π are fixed  → the waterline is self-coincident   • chirality FLIPS — text and hands are mirror-reversed   • a vertical object inverts about the waterline ; base-of-object meets base-of-reflection exactly on Π   • perspective in the reflection is that of R(C): the same vanishing points, mapped  READ OFF   • k real↔reflected correspondences: each pair's perpendicular-bisector plane must be the SAME Π   • reflected height / compression is lawful with view angle, not free   • everything in front of Π that R(C) can see appears — and nothing else  CONSISTENCY   recover (m̂, q̂) from correspondence pairs — must coincide ; check handedness of every reflected glyph   FORBIDDEN : a reflection containing an object with NO real pre-image (or dropping one plainly in front) ;               signage readable forward in the glass ;               reflected pose / expression differing from the subject ;               a floating reflection whose base does not meet the object on Π.
