class denselinkage.core.ports.Matcher(*args, **kwargs)

Bases: Protocol

match(pairs: Sequence[CandidatePair]) → list[MatchDecision | MatchError]

One outcome per input pair, aligned by position. A pair the matcher cannot decide yields a MatchError (never raises into the batch, so one bad call does not abort the rest).
