Essays

  Why schema-specific models can't leave home, the cell token, the four attention masks, and where zero-shot transfer actually comes from.
• 2026 RelGNN: reading a database as a set of atomic routes
  Why message passing goes blind on relational data, what an atomic route is, and one composite layer computed by hand.
