Overview

Employs statically-parsed Abstract Syntax Tree processing via the ‘parser` gem to correlate raw line-based deficits with high-level semantically meaningful concepts like Classes and Methods. This negates the line-number volatility often experienced by Large Language Models when patching test coverage.

Defined Under Namespace
