From Numbers to Interpretation

The first methods article explained the WDL foundation: expected score, expected-score loss, WDL Accuracy, and the main performance metri.

The second methods article introduced the post-WDL difficulty layer: all-legal difficulty, CCP Search Difficulty, CCP-v2 recursive forcing burden, probe/confirm search, root-branch diagnostics, Difficulty Pressure Quality, and Pressure Yield.

This third part explains how to read the actual output files.
