## Evidence gaps

> The repository license was not verified.
> Dependencies were not checked for known security issues. That does not mean there are none.
> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> 4 suggested change patterns have no matching file and are left out.
> Runtime versions and other prerequisites were not captured.
> Root development commands were not established. Check the root manifest and contributor guide.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
