Omar SobhandClaude Fable 5.1	0efb8be745	embedded3 PERF-3 P1-5 (c) part 2 + (d): the device tables persist across steps and are updated in place within the band — one DeviceCut with both phases' aperture / open / activity buffers (the predictor phase is a flag); the faces of the changed cells for apertures, distances, shifts and open flags, the imposition band's faces for the surface velocities, the changed cells for activity and owner, the changed and wall cells for the wall flux, the merged-cell CSR whole; RTX_E3_BAND_CHECK=1 compares every table against a full build (passed); slab CSV byte-identical, device moving/cg green; ny 124 rebuild block 1,910 → 1,578 ms per step (tables 442 → 132) ...

Omar SobhandClaude Fable 5.1	fe76413c66	embedded3 PERF-3 P1-4 (steps 1–3 + d): the band-persistent operator — CutGeometry marks re-evaluated corners; Mask::changed_cells (touched by either build, dilated by one); Level::patch re-derives the changed rows with the constructor's formulas on the kept level; the fine export patched likewise with the parent map as a parallel per-cell map; components plane by plane with a small union across planes; Problem::link_map (sparse) replaces the per-cell link lists on the per-step path; RTX_E3_BAND_CHECK=1 compares against full rebuilds (passed on the slab) — slab CSV byte-identical at every step, device moving/cg green; ny 124 rebuild block 2,569 → 2,119 ms per step ...

Omar SobhandClaude Fable 5.1	7fffbb1301	embedded3 S2-7b: the curved instrument's per-wall operator probe (curved_operator_probe) and RTX_E3_CURVED_SCHEME; host prototype RTX_E3_WALL_FOOT=centroid (the shear closure's wall velocity at the foot from the open part's CENTROID, not the face centre — on a rotating wall the two feet are ½h(1−α) apart: rigid-mode probe residual 4.5× smaller, the rotating wall's offset −0.022 → ±0.002 h, its cut pressure zeroth → first order); default off, device refuses it ...

Omar SobhandClaude Fable 5.1	599023d786	embedded3 S2-7b A1: the moving wall's mass flux from the body's true normal at the wall foot (RTX_E3_WALL_FLUX=true, host prototype, device refuses it) — the wall flux of a rotating cylinder 5e-3 → 1e-9 of ΩR h², the rotating wall's cut-cell pressure error 0.33 → 0.11 (n 16) / 0.30 → 0.09 (n 32) of ρ(ΩR)², full cells second order; the rotating wall's offset unchanged (−0.02 h) ...

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) ...
