Owns the inputs to the field-map kernel — evoked info, head and helmet surface geometry, MRI / head coordinate transforms, channel picks and SSP projectors. Whenever any of these change via the (mutex-protected) setters, computeMapping rebuilds the dense (n_vertices x n_channels) matrix and emits it back to the data worker, so the streaming pipeline never stalls.
