HDA Protocol Dissects Agentic Gains from Prompt Optimization
October 14, 2026
Harness-Delta Attribution (HDA) decomposes performance gains in agentic systems into artifact-driven overfitting, test-time scaling, or residual generalizable improvement. The protocol evaluates 11 executor models and three evolution frameworks across mathematical tasks.
