New go/internal/domain/matching package porting three helpers from scripts/match_payments.py: - BuildNameVariants: normalized ASCII variants from a member name (nickname in parens, last/first split, len<3 filtered); variants[0] is always the full base name — MatchMembers relies on this invariant. - MatchMembers: auto/review confidence matching with an exact-name short-circuit pass that prevents nickname substrings (tov) from firing inside longer surnames (ottova); common-surname filter for review tier. - FormatDate: nil/empty/""/serial int/float64 (since 1899-12-30, fractional days supported)/YYYY-MM-DD passthrough/garbage → never errors. - InferTransactionDetails: composes BuildNameVariants+MatchMembers+ ParseMonthReferences; falls back to sender-only member match and date-derived month when text carries no signal. 21 table-driven tests; all expected values verified against live Python on 2026-05-06. go-build, go-test, go-lint all clean.
