"""Tests for the 2026-06-11 neutralizer (docs/neutralizer_proposal.md).

Covers:
  1. Audit-driven demotions: contested words are LIQUID with attenuated dV,
     while protected words (love) keep their SOLID charge.
  2. Demoted positive words resolve by context instead of dragging
     sentences positive on their own.
  3. Two-faced slang (cooked/snapped/sheesh) doom-vs-praise duality via
     SOLVENT dissolution.
