- core/cell_kind.cuh holds KIND_ACTIVE/INNER/OUTER (was a constexpr in
blocks.cu that step/block_channel.cu and the channel_root.cpp shim
relied on or redefined); blocks.cu, block_channel.cu and the shim now
include it.
- blocks.cu checks the lattice/model #error guard before the
BLOCK_ROOT_BC guard and mode includes, so an unsupported build reports
the real reason first.
- operators/block_collision.cuh includes what it uses (params, macro,
SRT/MRT collision) instead of relying on blocks.cu's include order.
Preprocessor-only: same kernels, same statements, same arithmetic.
