Phase 35-A: BENCH_MINIMAL gate function elimination (GO +4.39%) - tiny_front_v3_enabled() → constant true - tiny_metadata_cache_enabled() → constant 0 - learner_v7_enabled() → constant false - small_learner_v2_enabled() → constant false Phase 36: Policy snapshot init-once (GO +0.71%) - small_policy_v7_snapshot() version check skip in BENCH_MINIMAL - TLS cache for policy snapshot Phase 37: Standard TLS cache (NO-GO -0.07%) - TLS cache for Standard build attempted - Runtime gate overhead negates benefit Phase 38: FAST/OBSERVE/Standard workflow established - make perf_fast, make perf_observe targets - Scorecard and documentation updates Phase 39: Hot path gate constantization (GO +1.98%) - front_gate_unified_enabled() → constant 1 - alloc_dualhot_enabled() → constant 0 - g_bench_fast_front, g_v3_enabled blocks → compile-out - free_dispatch_stats_enabled() → constant false Results: - FAST v3: 56.04M ops/s (47.4% of mimalloc) - Standard: 53.50M ops/s (45.3% of mimalloc) - M1 target (50%): 5.5% remaining 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
