Omar SobhandClaude Fable 5.1	d25a36d908	embedded3 S2-7b: the curved-wall instrument (tests/embedded3_wall_position_curved.rs: Taylor–Couette between embedded cylinders, rigid-rotation linear mode, outer-driven mode; walls' effective radii, pressure error by cell class against the exact p(r), wall-flux and ghost diagnostics); the sphere operator probe's sub-bands and force units; two host prototypes, default off, device refuses them: RTX_E3_WALL_EXCHANGE=axisfoot (the axis exchange takes the wall velocity at the axis foot — the S2-7 default read the solid face's own value, exact only for a uniform wall velocity: rigid rotation A 1.012 → 1.003) and RTX_E3_CONV_SIDES=exact (convective mass fluxes from the sides' own apertures; moves nothing) ...
