Correctness Benchmark: Phase 6 + Session 13 + Tier 2 Comparison

Measures actual correctness improvement across three versions:
1. Phase 6 only (semantic tension + specialization)
2. Phase 6 + Session 13 (+ consciousness stack gates)
3. Phase 6 + Session 13 + Tier 2 (+ intent analysis + identity validation)

Tests against ground truth with diverse query types and scoring metrics.
