Detailed Description

One digitizer point: kind (cardinal/HPI/EEG/extra), ident, 3D position in FIFFV_COORD_HEAD.

Field layout matches fiffDigPointRec on disk. The (kind, ident) pair is the lookup key used everywhere else in the codebase — for example, the LPA/Nasion/RPA fiducials are found by searching for kind == FIFFV_POINT_CARDINAL and ident == 1 / 2 / 3.
