Omar SobhandClaude Opus 5.5	0150f79a4a	embedded3 R6-2: the moving mask's classification on the device (RTX_E3_MASK_DEVICE=1, needs RTX_E3_GEOM_DEVICE=1) ... - e3_mask.cu: the changed set (touched by either build, dilated), the faces of the changed cells, per changed cell the fluid flag / space-time activity / GCL entry and the merging master, per face the kind, the step aperture and open flag and the open-part centroid shift (compute_face_shifts' cv geometry), the GCL table's wall cells / areas / table with the correction, the merged cells' CSR (slave ranks from the master's distinct face neighbours), the imposition band's faces; block scans for ascending stream compaction and the CSR's exclusive scan. fp64, FMA contraction off. - step/device/mask.rs DeviceMask: snapshots the previous apertures / volumes / evaluated cells before the R6-1 geometry kernels, runs the classification into DeviceCut's persistent tables (a, open, open_pred, active, active_pred, owner, shift, wall_flux, fold_ptr/fold_idx) and returns the compact values (MaskUpdate); the GCL sums in ascending order on the host. DeviceCut::update_after_device_mask: only the band's surface velocities remain (band list compacted on the device). - maskupdate.rs: Mask::from_update — the host mirror from the old mask's step arrays and merging map (moved) and the mask retired a step earlier (instantaneous arrays, pooled), the compact values scattered; incremental fluid count / anchor / side check; the fresh-cell refill over the changed set. - RTX_E3_BAND_CHECK=1 with the knob: the host rebuild on copies (from_cut, face shifts, step apertures, merging, GCL, refill) against the mirror, bit for bit, and every device table against a full build. - Knob off: the host path unchanged (Mask::from_parts, Solver::configure_mask and retire_mask are the same statements); profile laps under RTX_E3_MOVING_PROFILE only.

Omar SobhandClaude Opus 5.5	f5f0ffdd2a	embedded3 R6-1: the body's φ and the cut geometry on the device (RTX_E3_GEOM_DEVICE=1) ... - e3_geom.cu: corner φ on the narrow band (the flag test's circle + capsule around the step's centreline polyline + span cuts + fillet union), face apertures / face-centre φ by the Kuhn triangles, cell volumes by the six Kuhn tets and wall vectors by closure — CutGeometry::build_from in fp64, host operation order, FMA contraction off. - Body::with_device_sdf / DeviceSdf: the device form of φ (the host passes the polyline per step); the flag wake test attaches it (same arithmetic as its closure; the polylines factored out unchanged). - step/device/geom.rs DeviceGeom: persistent φ / bound / volume / wall buffers; the face tables written straight into DeviceCut's predictor apertures and distances (update skips their scatters); the host mirror = the band's entries gathered compactly onto recycled arrays of retired device generations (GeomPool; band-list history) — Mask::from_cut classifies it. - RTX_E3_BAND_CHECK=1 with the knob: mirror AND device tables against the host build_from bit for bit on every refresh. - Knob off: byte-identical (slab ny 62 one period CSV = main's); host suite 21/21.
