…durations The partitioning algorithm used AST body length as a fallback weight when historical durations weren't available. This added complexity without much benefit. Now tests without durations are shuffled randomly and assigned equal weight, simplifying the logic while achieving better distribution. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
