 * ADR-052 Action A4.5: Final Quality Gates Verification
 *
 * This test file validates the quality gates for the coherence module:
 * 1. All 6 engine adapters are functional
 * 2. CoherenceService initializes successfully
 * 3. MCP tools are registered (4 tools: check, audit, consensus, collapse)
 * 4. False negative rate: Known contradictions must be detected (100%)
 * 5. False positive rate: Coherent inputs must not be falsely flagged (<5%)

/**
 * Test Summary for ADR-052 A4.5 Quality Gates:
 *
 * 1. Engine Adapter Functionality:
 *    - All 6 adapters (Cohomology, Spectral, Causal, Category, Homotopy, Witness)
 *    - Can be instantiated without errors
 *
 * 2. CoherenceService Initialization:
 *    - Successfully initializes with fallback enabled
 *    - Tracks statistics correctly
 *
 * 3. MCP Tools Registration:
 *    - 4 tools registered: check, audit, consensus, collapse
 *    - Tools have correct names and domains
 *
 * 4. False Negative Rate (0% allowed):
 *    - Known contradictions (opposite embeddings) are detected
 *    - All contradictory pairs in test set are flagged
 *
 * 5. False Positive Rate (<5% allowed):
 *    - Coherent embeddings are not flagged as contradictions
 *    - 100 coherent test cases with <5% false positives
