Changes: - scripts/box/pgo_fast_profile_config.sh: Expanded WS patterns (3→5) and seeds (1→3) for reduced overfitting and better production workload representativeness - PERFORMANCE_TARGETS_SCORECARD.md: Phase 68 baseline promoted (61.614M = 50.93%) - CURRENT_TASK.md: Phase 68 marked complete, Phase 67a (layout tax forensics) set Active Results: - 10-run verification: +1.19% vs Phase 66 baseline (GO, >+1.0% threshold) - M1 milestone: 50.93% of mimalloc (target 50%, exceeded by +0.93pp) - Stability: 10-run mean/median with <2.1% CV 🤖 Generated with Claude Code Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
