Extends Phase 75-1 pattern to C5 class (28.5% of C4-C7 ops): - Created 4 new boxes: env_box, tls_box, fast_path_api, TLS variable - Integration: 2 minimal boundary points (alloc/free for C5) - Test strategy: C5-only isolation (baseline C5=OFF+C6=ON, treatment C5=ON+C6=ON) - Default OFF: zero overhead when disabled Results (10-run Mixed SSOT, WS=400, C6 already enabled): - Baseline (C5=OFF, C6=ON): 44.26 M ops/s (σ=0.37) - Treatment (C5=ON, C6=ON): 44.74 M ops/s (σ=0.54) - Delta: +0.49 M ops/s (+1.10%) Status: ✅ GO - C5 individual contribution confirmed Cumulative since Phase 75-0: +2.87% (C6) + 1.10% (C5) = potential +3.97% combined Next: Phase 75-3 (test C5+C6 interaction + non-additivity + promote to preset default) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
