Inferring Polkadot validator operators through nominator identity convergence

Measuring Polkadot at the operator level is harder than counting validators. One operator can run several validators, while a validator that appears independent may simply lack an explicit super-identity relationship connecting it to the rest of its operation.

Nominations provide another source of public evidence. When every account nominating an operator-unresolved validator belongs to the same registrar-attested identity graph, that convergence can be used to associate the validator with the operator behind the graph.

I call this method Nominator Identity Convergence. It is a deterministic, snapshot-based heuristic for finding probable operator associations that are not expressed directly by the validator account itself.
