rtx-cfd 3D Stage 1 item 1: three_d::{Grid3, poisson} — the 2D Poisson stack transcribed to a seven-point operator (sanitised coefficients, 2×2×2 Galerkin aggregation, (i+j+k)%2 colouring, periodic z, run_pcg line for line, PcgCache3); gate 1 HELD: nz=1 bit-identical to the 2D solver (solution + iterations, lex + red-black, cached/uncached); extrusion z-invariant to the solve's accuracy (bit-identical planes for lexicographic decoupled); probes for the aggregation/colouring interaction
