Layer 1: Deterministic rule scanner — federal Fair Housing lexicon plus state-specific protected classes (CA/TX/FL/NY/AZ in v1) plus MLS/NAR puffery and contact-leak rules.

Layer 2: AI nuance pass for context-dependent issues. Every AI flag must cite a rule from the registry — no free-form opinions.

Layer 3: Self-test loop. When you apply suggestions, the cleaned version is automatically rescanned. The verdict you see is the rescan result.
