WPL.Enforce.Matcher (WPL Validator v1.9.0)

Copy Markdown View Source

Fuzzy exercise-name matcher for the Pass-3 enforcement engine.

Ported from wpl-validator-ts/src/enforce/matcher.ts. Pure functions. Any change here is a change to the safety contract — add a conformance fixture with every behavioral change.
