/**
 * Regression test for A2A message rendering fix
 *
 * Verifies:
 * 1. GET /api/entities includes messageQueue in response
 * 2. speak-to sets entity.message in correct format (no duplicate assignment)
 * 3. Web portal parseEntitySource handles non-uppercase character names
 * 4. Entity source patterns match various character name formats
 *
 * Android regex fixes (ChatRepository.kt) are validated via source pattern matching
 * since the same patterns are used on both platforms.
