Omar SobhandClaude Opus 5.5	171da41ed1	Merge r8a-span-uniform-fsi (R8-a: the first coupled 3D FSI, span-uniform; default-off). Merge fixes: the load-route observers of R8-a (to_load_sink) and R8-c (sink(LoadKind, …)) both kept on the same summands (both inert by default); the harness's DeviceSdf gains plate: None (R8-c's new field). Merged-tree gate: slab ny 62 default / BAND_CHECK / all-host / uniform plate byte-identical to main's base; device suites 2/2, 3/3; the coupled harness reproduces R8-a's recorded slab march row for row (478 rows) ...

Omar SobhandClaude Opus 5.5	12a27c6fca	R8-a: span-uniform coupled FSI2 on embedded3 — DeviceStep snapshot/restore, operator-route load sink, harness fsi2_embedded3.rs ... - embedded3 DeviceStep::snapshot/restore (step/device/snapshot.rs): the start-of-step device fields + the moving body's host records; a restore rebuilds the R6 persistent geometry/classification, the predictor tables, the hierarchy and the guess basis. Only called by the new harness (existing paths untouched). - exchange::set_load_sink: every contribution of the operator load route (p W, wall shear, diffusive/convective exchange) with position/component/part; None by default, the routes' sums unchanged (slab ny 62 CSV byte-identical to r6_1/base_slab62.csv). - rtx-fsi feature cuda (= rtx-cfd/cuda) and tests/fsi2_embedded3.rs: the 2D rtx-fea flag (35x2 Quad8, TL, Newmark 0.7) drives the capsule's centreline per coupled step; the route's contributions are distributed onto the wetted nodes per unit span; Aitken subiterations each re-run the fluid step from the snapshot.

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	73e4c7513e	embedded3 R6-3 default ON: the device Poisson setup (RTX_E3_POISSON_DEVICE=0 restores the host) and the p-only field transfer (RTX_E3_FIELD_P_ONLY=0 restores the full one) ... Both held their two-period 3D ny 62 gate on da2945f (default span, CSV identical to round 3's two-period CSV; with the check: 1176 poisson and 118 hierarchy checks identical, 0 differ).

Omar SobhandClaude Opus 5.5	da2945fcf5	embedded3 R6-3: the hierarchy rebuild's level 0 on the device (RTX_E3_POISSON_DEVICE=1) ... DeviceCg::new_device: level 0 by refresh_device, level 1's operator coarsened on the device (Level::coarsen per coarse cell, children in ascending index order) and brought down, levels 1.. by Hierarchy's loop (Hierarchy::chain_below, export_levels), level 0's children lists on the device. Falls back to DeviceCg::new when the hierarchy would stop at level 0. RTX_E3_BAND_CHECK=1: every level against export_hierarchy, the fine structures as refresh_device's check, the raw components' singular flag. DeviceCg::new gains profile laps; DeviceVcycle::new split into upload_level + from_levels, export_hierarchy into export_levels (same code).

Omar SobhandClaude Opus 5.5	b00f297ef7	embedded3 R6-3: RTX_E3_FIELD_P_ONLY=1 (default off) — the rebuild's field transfer limited to p when the classification and imposition ran on the device ... The download waits until the step's rebuild route is known; with the device mask and device imposition the host rebuild reads and writes only the pressure (the fresh cells' refill), so u, v, w and the old velocities stay on the device (their upload wrote back the values just downloaded). Not under RTX_E3_BAND_CHECK (its references read the whole mirror). Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>	2026-09-25 03:28:30 -05:00
Omar SobhandClaude Opus 5.5	348f4621d1	embedded3 R6-3: the moving path's Poisson setup on the device (RTX_E3_POISSON_DEVICE=1, default off) ... The operator (poisson_operator + merge_small_cells), Level::new's activity, masked couplings, z links and cell/colour lists, the link CSR, the components' count and singular count (lock-free union-find), and the f32 fine export with its parent map, built on the device from DeviceCut's projection tables into the CG's and V-cycle's persistent buffers (e3_pset.cu, poisson/device_cg/setup.rs). RTX_E3_BAND_CHECK=1 compares every structure against the host build bit for bit. Fallback to the host setup (logged once) with gradient weights or a periodic z of <= 2 planes.

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	d9847cd818	Merge R6-2: the moving mask's classification, merging, face shifts and GCL table on the device (RTX_E3_MASK_DEVICE=1, default off); on top of R6-1's default-on device geometry. Merge fix: the mask knob requires the geometry not switched off (it required RTX_E3_GEOM_DEVICE=1 before the geometry became the default). Gate on the merged tree: slab ny 62 one period default and mask-on+BAND_CHECK both byte-identical to main's base, 0 differs; device suites 2/2, 3/3 ...

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	91fbf86026	embedded3 R6-1: the device geometry default ON (RTX_E3_GEOM_DEVICE=0 restores the host build); a body without a device form of φ falls back to the host, logged once, nothing allocated ...

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.

The first form redirected the V-cycle's own e3_cg_scatter_f64 launch (a replace-all on the launch name) and failed every gate — the symbol table is the first thing to read when adding to a module ...
