"""Tests for Interpretation-in-Map (step 5).

Acceptance: a customer interpretation is judged against the existing map, using
only assess_interpretation; affected regulations/obligations are referenced from
the map; unsupported domains (wastewater/chemicals) are flagged
future_corpus_needed, not pseudo-evaluated; output is customer-readable.
