Case contract

Input a dict. Unknown country (not AA, BB, CC) returns ["country_unknown"]. Values are stripped of all whitespace (None counts as blank). Issues, in order: line1_missing; line2_duplicate when a non-blank line2 equals line1 ignoring case; city_missing; for AA region_missing or region_invalid (not two letters); for AA and BB postal_missing or postal_invalid (AA 5 digits, BB 4 digits); for CC postal_unexpected when a non-blank code is given.

Why this case matters

Completeness checks gate address entry; false positives block valid orders and false negatives let undeliverable addresses through.

One recorded failure
