pytc.solver.isdf_xtc_ccsd._read_x_rank_panel_major(x_backing, nocc, m0, m1, panel_size)

Rank-major twin of _read_x_rank_panel(), returning rank-leading (panel_size, nvir, nvir) panels – already the layout the panel kernels consume, and one CONTIGUOUS disk read per panel instead of ~nmo^2 strided chunks. Zero-pads the rank tail on axis 0.
