## Purpose

Find the testing gaps that actually matter — untested *behaviors* weighted by risk — instead of chasing a line-coverage percentage that can be high while the important paths remain unverified.

## When to Use

- Deciding where to invest limited testing effort next.
- Coverage numbers look acceptable but bugs keep escaping to production.
- Before modifying risky code, to find out what's currently protecting it (and what isn't).

Differs from [Test Generator](../test-generator/): that writes tests; this decides *which* tests are worth writing first.
