Edge cases the join exposes

Cases a classifier trained on clean vendor invoices would get wrong. Counts are pairs.

Campus classifier missed the campus (QuickBooks class says otherwise) — 9
Reply / forward threads (the invoice is buried in a conversation) — 9
Forwarded by an internal address (sender ≠ vendor) — 6
Sent via QuickBooks notifications (sender ≠ vendor) — 8
One bill, several messages (reminder + replies) — 5
Same vendor coded to different accounts — 1
