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) ...

Omar SobhandClaude Fable 5.1	b80af59ca4	embedded3 S2-7: oblique instrument gains registration sweep / slope subset / z-flow skip / merged-cell count (RTX_E3_OBLIQUE_{C0_SHIFTS,SLOPES,ZFLOW,NS}) and the operator probe (oblique_operator_probe: predictor acceleration on the exact centroid-valued field by aperture band, cut-cell divergence under four valuations, spurious pressure; z-flow control); two host prototypes, default off, device refuses them: RTX_E3_CV_SIDES=exact (the momentum CV's side apertures from the interpolant on the half faces / cell-centre planes) and RTX_E3_WALL_ORDER2=centroid (the quadratic wall gradient's second point at the neighbour's centroid distance); quad_fraction / tri_area_fraction lifted to module fns (default path digit-identical: oblique record, host suite 21/21, device cut tests) ...

Omar SobhandClaude Fable 5.1	77ecc54b24	embedded3: GuessBasis re-export behind the cuda feature (the host-only build broke); A2 build: no convective exchange with prescribed faces (RTX_E3_EXCHANGE_CONVECTION=off, host + device bit 10, load route consistent) ...

Omar SobhandClaude Fable 5.1	fdfb6da769	embedded3 S2-5: the cut wall sat ½(1−α)h inside the body — cross diffusion over the open-part centroid spacing (RTX_E3_DIFFUSION_CENTROID; host + e3_cut.cu, shift tables, point-implicit excess); flat-wall effective-position instrument; DFG 2D-1 ladder tests (device + host); knobs tried and refuted along the way (oblique distance, axis exchange, centroid pressure gradient) ...
