//! Core domain types for the Fidget Spinner frontier machine.
//!
//! Fidget Spinner is intentionally austere. The canonical ledger is a narrow
//! experimental spine: frontiers scope work, hypotheses and experiments are the
//! only graph vertices, and bulky context lives off the hot path as artifact
//! references.
