 A bootstrap meta-schema is stored as a self-referencing seed node (`type === hash`). All other schemas are registered as nodes typed by that meta-schema. Payloads can reference other nodes via `format: "cas_ref"` fields; the library provides traversal, reference extraction, and integrity verification.
