Research direction

Start with the System.Numerics.Tests.Perf_Matrix4x4 benchmark source links, including Perf_Matrix4x4.cs, and review the linked history reports for the baseline and compare commits. The report records 77 improvements but does not identify a requested code change or acceptance criterion, so triage must first determine which benchmark result has an actionable cause and what measurable outcome would count as done.
