Field Mapping Audit — Prevent Interface Bugs
============================================

Field-mapping audit checklist:
☐ List every field that moves from A → B
☐ Confirm names match (case + underscores)
☐ Confirm types match (string/number/bool)
☐ Log sample values (first 40 chars)
☐ Test one real record end-to-end
☐ Add a guard: if field missing, fail loud

Debug output example format:
field_name="customer_email" value="steve@exam…"
