Corporate-card reconciliation engine

A review queue that matches card lines to receipts, calendar, and notes pulled through an audited read-only gateway, with evidence tiers and trip clustering. Evaluated at 90–98% precision against the finance lead's real books — which it corrected.

• Domain rules encoded from the person who does the work: a human receipt note outranks the GL code; trips are grouped, never proposed
• Precision measured before anyone was asked to trust it
