CGH0S7	a628b8e2ff	Fix fourth-order C lopsided and KO stencil indexing	2026-05-14 15:19:36 +08:00
CGH0S7	9e51793499	Add full FD order support (2nd/4th/6th/8th) to C derivative kernels via ghost_width dispatch ... Wrap each C kernel in #if (ghost_width == N) blocks matching Fortran stencil coefficients from diff_new.f90, kodiss.f90, and lopsidediff.f90. Add fast-path indexing for ord=1,4,5 in share_func.h.
