Omar SobhandClaude Fable 5.1	77fda442c6	embedded3 PERF-3 P1-5 (c) part 1: scatter kernels (e3_scat_{f64,f32,u32,i32}) in the CG module; the refresh's seven f64 coefficient arrays and z links, and the V-cycle fine level's f32 arrays and maps, scattered on the changed rows into persistent buffers (DeviceVcycle::refresh_fine_rows) — slab CSV byte-identical, band check passed, device moving/cg green; ny 124 rebuild block 1,895 → 1,748 ms per step. 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 ...

Omar SobhandClaude Fable 5.1	d4cd7d9545	embedded3 PERF-3 P2: the Poisson initial guess by projection onto the last K corrections of the same corrector index (GuessBasis, DeviceCg::project_guess: Gram matrix rebuilt per solve, Cholesky with pivot dropping; e3_cg_axpy) behind RTX_E3_POISSON_PROJECT=K (default 0, digit-identical); static DFG 2D ny 122: CG 9.5 -> 2.5 per step, loads identical to 4 digits; the moving flag: -4 % only (consecutive corrections nearly uncorrelated); RTX_E3_POISSON_PROJECT_DEBUG prints the residual before / after ...

Omar SobhandClaude Fable 5.1	3b3d6c84c0	embedded3 item 9b: the device step carries a static cut-cell mask (e3_cut.cu: cut predictor, apertured merged continuity with the fold, owner-read corrections; device CG off-stencil links) — host = device to 2e-10 (CFD1 cylinder nz 4) and 4e-14 (sphere) under tight tolerances ...

Omar SobhandClaude Fable 5.1	765ba6d3f6	rtx-cfd embedded3 item 3: e3_cg.cu (FMA off) + poisson::device_cg::{DeviceCg, DevicePcgCache, solve_pcg_device_cached}; gate 3 HELD: device CG = host PCG (9 / 9 iterations, |Δp| ≤ 1.5e-14 relative, run-to-run bit-identical, anchor exact, mean 9e-16) ...
