The gbrain schema already had type='operational' for build notes (3 pages already lived there) and type='original' for atomic ideas—but 9 build notes had been misclassified as 'original', polluting the public feed. The fix wasn't a new 'is_build_note' flag; it was using the existing taxonomy correctly. The convention was established; the author just wasn't using it. Lesson: when something feels wrong, check whether the schema already has the distinction you need before adding fields or filters.
