 "why": "MANUS question 2026-08-04 (\"how did you search, with what terms?\") exposed that every duplicate/pairing search this session was title-gated (title substring + hand-picked probes). Title matching is structurally blind to this archive's most common duplicate form: metadata packets, capture-titled records, and superseded variants that carry DIFFERENT titles for the SAME text.",
