Protocols
How the data was made. Each Protocol is the reproducible definition behind an open Dataset — an ordered sequence of typed steps that fetch, resolve, tier, export and gate the data. Every step is a versioned operator, a SQL model, or (rarely) an opaque command; every Protocol’s output is checked against a finetype schema contract before it ships.
This is a read-only view for browsing and discovery — authoring lives elsewhere.
