    description: >-
      Declared outbound edges. Each entry is either `<label>: <page title>` - the
      label drawn from instructions/link-taxonomy.md and authorised per
      destination by the source collection's `outbound:` block - or a bare page
      title for an edge whose label has not been declared yet. The bare form is
      the pre-4.0.0 shape and is what `lint` reports until the migration reaches
      the page; it is accepted rather than rejected so that a corpus stays
      readable while it is being converted.
