in unigraph/handlers/ensv1/RegistrarController.ts, the legacy 5-arg variant NameRegistered(string name, bytes32 label, address owner, uint256 cost, uint256 expires) doesn't map cost → baseCost in its arg re-mapping (the NameRenewed variants do), so handleNameRegisteredByController writes Registration.base = null for every legacy-controller registration. observed on a mainnet backfill: zero registrations with base set through mid-2021.
