Signature, parameters, and return type

/** Stable codes of lock-contract violations the fake refuses instead of deadlocking. */
type MemoryLockContractErrorCode =
/** Re-acquiring a key already held by the surrounding callback — PostgreSQL would self-deadlock. */
'reentrant-lock'
/** Any public lock API called inside another lock callback — README forbids nesting; the fake refuses it. */
 | 'nested-lock-api'
/**
 * A locked-mutation handle used after its callback settled. The PostgreSQL handle is bound to
 * a connection that was already committed/rolled back and released; the fake refuses rather
 * than silently dropping the write or applying it outside the lock.
 */
 | 'handle-outside-callback';
