/**
 * Level 4: Content Quality Tests
 * 
 * These tests verify that the Fast Agent Panel generates responses
 * matching the content quality and depth shown in audit_mocks.ts.
 * 
 * The audit_mocks.ts defines banker-grade entity profiles with:
 * - Structured funding info (stage, totalRaised, lastRound with coLeads, participants)
 * - People profiles (founders, executives with backgrounds and credentials)
 * - Product pipeline (platform, modalities, leadPrograms, differentiation)
 * - Contact points (primary, media, outreachAngles)
 * - Source attribution with credibility ratings
 * - Persona hooks for quality gate evaluation
 * 
 * These tests require actual LLM responses and may take longer to complete.
