/**
 * Maps a cryptographically-verified EUDI Wallet PID presentation to a demo
 * patient identity in this dataspace.
 *
 * Demo semantics (decided for the hackathon): every successfully verified wallet
 * is mapped to a fixed synthetic patient (`patient1`). A real wallet's PID will
 * not match the synthetic Synthea cohort, so a name+birthDate lookup would lock
 * the holder out. The *identity* is therefore cosmetic — the point is that the
 * holder proved control of a real EUDI Wallet credential. The verified name is
 * surfaced as the display name so the demo shows "you, verified via your wallet"
 * over a synthetic health record.
 *
 * Swap `mapPidToPatient` for a real Neo4j name+birthDate resolver later; the
 * call sites (status route, Credentials provider) depend only on this contract.
