Omar SobhandClaude Opus 5.5	02ab155022	R8-h: a flat-tipped flag for the 3D solver (default off, byte-identical when off) ... DeviceSdf gains `tip_corner: Option<f64>` (None = the capsule, as before; Some(r_c) = a FLAT tip through the centreline's last point, normal to the last segment, corners rounded to r_c): the last segment becomes a ray for the lateral distance and the strip is cut by the tip plane with the span cut's rounded intersection. Host twin (plate.rs: closest/tip_axial/ flat_cap, polyline and plate bodies) and the device φ and velocity (e3_geom.cu geom_phi_at / body_velocity / plate_dist; GeomSdf flat_tip + tip_corner) expression for expression. Knobs: flag test RTX_E3_FLAG_TIP=flat + RTX_E3_FLAG_TIP_CORNER (default 0.00125 m; the tip inset defaults to 0 with the flat tip; the host φ is the device form's); R8-a harness RTX_E3FSI_TIP=flat + RTX_E3FSI_TIP_CORNER (the centreline gains node A as a 36th station). New host test embedded3_flat_tip (G2 geometry: tip plane at the last point, r_c = half = the capsule pulled back by half to 4e-17, cut volume and wall area vs the analytic rounded rectangle at ny 62/124/248).

Omar SobhandClaude Opus 5.5	9c2ae32061	R8-c: the 3D flag's interface — deformed-plate body (host + device φ/ub) and the conservative load transfer onto a Hex20 plate ... - embedded3/plate.rs: PlateSurface (mid-surface on span stations) and the host evaluation of DeviceSdf (phi_host / velocity_host / is_flag_host), expression for expression e3_geom.cu; a span-uniform plate is the polyline capsule to the bit; first-order spanwise-slope correction. - e3_geom.cu / device/geom.rs: plate branch of geom_phi_at and body_velocity (nst = 0 keeps the polyline path unchanged). - cutwall.rs / exchange.rs: the load loops observed through a sink (sums unchanged); interface.rs: Mask::cut_wall_loads (every summand of cut_wall_force with its foot), HexPlate (R8-b's Hex20 lattice numbering), consistent point-force transfer conserving force and moment to round-off, locate() for the transpose, mid_surface() for the fluid body. - flag test: RTX_E3_FLAG_BODY=plate, _STATIONS, _TWIST, _TRANSFER(_EVERY, _CSV, _NODAL); all default off.

Omar SobhandClaude Opus 5.5	2c054ccc91	embedded3 R6-2 step 2: the band's surface velocity at the foot (ub) and the rebuild's imposition on the device (RTX_E3_UB_DEVICE=1, default off) ... e3_geom_ub / e3_geom_impose / e3_geom_seam: the flag body's surface velocity (DeviceSdf::vel, the centreline's velocity per point) at the foot from the trilinear interpolant of the device corner phi, and at the face centre for the band's solid faces of the uploaded field (a cut mask has no ghosts); the host mirror of ub by a packed download. RTX_E3_BAND_CHECK=1 compares the device ub with Mask::surface_velocity_at and the imposed u, v, w with impose_from, bit for bit; check_against now compares ub on every band face (zeros included).

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.
