Harmonic Frame Analysis
Calculates frame frequency and worst 1% stalls via harmonic averaging, avoiding arithmetic skew.
Target-Isolated Heap
Inspects memory inside the target context via a three-tier cascade, avoiding OOPIF host blindspots.
Dynamic Welch's t-Test
Flags regressions only when statistically significant ($p < 0.05$) based on calculated degrees of freedom.
