## New (5)

- Coverage not measured — test suite did not build
- Dimension evaluation failed
- No tests found
- The README is a single-file documentation of the mechanize gem rather than an internal architecture document describing how the library works and why it was built. (README.md)
- The README mentions security vulnerability reporting at GitHub but does not link to SECURITY.md or describe the policy. (README.md)
