What it is
Supercov scores code quality with Jev and measures test coverage, turning uncovered paths into actionable queries for coding agents to fix and test.
How it uses Jev
Jev answers twelve Noul properties per source file, such as long_method and deep_nesting, to score code quality. The agent uses these scores to decide what to fix first.
Primitives:noul
Technique worth stealing
Use Jev to answer yes/no questions about each file, then do the arithmetic yourself for checkable scores.

Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
