Module catalog 

The registry catalog substrate: transactional, Cx-free table storage.

The catalog is the authoritative storage behind the Registry; see the README section “Contract: registry catalog substrate”. The kernel defines the catalog contracts – schema, rows, transactions, the append-only journal, snapshots, deltas, overlays, read-only views, and replay – and ships a default store::CatalogStore; libraries supply higher-level behavior over them.
