      Open vocabulary: write the source''s own wording in the field when nothing here
      fits, because the value is required and a closed range would discard the whole
      acquisition over one unrecognised word. Only a vocabulary value carries an `instantiates`,
      so an acquisition outside it resolves to the base class until normalization
      maps the wording back on -- which is why `acquisition_type` is derived rather
      than extracted, and why an unmapped modality is worth reporting.'

  brain_coverage:
    name: brain_coverage
    description: 'How much of the brain the acquired volume contained. This is the
      extent the SCANNER sampled, and it is a third axis distinct from the two the
      schema already carries: `Analysis.spatial_scope` is what the analysis tested,
      and `InferenceSettings.correction_scope` with `search_volume` is where multiple
      comparisons were controlled. A voxelwise analysis over a volume that clipped
      the cerebellum is `whole_brain` in scope and `partial` here, and an ROI analysis
      of a whole-head acquisition is the reverse. Never infer this from either of
      those.

      It describes the volume behind the REPORTED results. A scan that clipped a structure
      in participants who were then excluded is `whole_brain`, because the analysed
      volume was not clipped; calling it `partial` would say the opposite of what
      the results rest on.

      A field of view or slice prescription in millimetres is not by itself a statement
      of coverage. Where only the geometry is given, the value is an inference and
      `value_source` records it as one. Which structure a partial volume missed is
      not a field of its own -- the evidence span carries that detail.'
