Key changes: - Phase 83-1: Switch dispatch fixed mode (tiny_inline_slots_switch_dispatch_fixed_box) - NO-GO (marginal +0.32%, branch reduction negligible) Reason: lazy-init pattern already optimal, Phase 78-1 pattern shows diminishing returns - Allocator comparison baseline update (10-run SSOT, WS=400, ITERS=20M): tcmalloc: 115.26M (92.33% of mimalloc) jemalloc: 97.39M (77.96% of mimalloc) system: 85.20M (68.24% of mimalloc) mimalloc: 124.82M (baseline) - hakmem PROFILE correction: scripts/run_mixed_10_cleanenv.sh + run_allocator_quick_matrix.sh PROFILE explicitly set to MIXED_TINYV3_C7_SAFE for hakmem measurements Result: baseline stabilized to 55.53M (44.46% of mimalloc) Previous unstable measurement (35.57M) was due to profile leak - Documentation: * PERFORMANCE_TARGETS_SCORECARD.md: Reference allocators + M1/M2 milestone status * PHASE83_1_SWITCH_DISPATCH_FIXED_RESULTS.md: Phase 83-1 analysis (NO-GO) * ALLOCATOR_COMPARISON_QUICK_RUNBOOK.md: Quick comparison procedure * ALLOCATOR_COMPARISON_SSOT.md: Detailed SSOT methodology - M2 milestone status: 44.46% (target 55%, gap -10.54pp) - structural improvements needed 🤖 Generated with Claude Code Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
