## Evidence gaps

> Health figures were updated after the written guide, so the guide may describe older code.
> Dependencies were not checked for known security issues. That does not mean there are none.
> RepoPilot has not run the setup commands or tests.
> No public API or start-up file could be picked out from the file names.
> The file list is newer than the written guide, so descriptions and suggested changes may describe older code.
> 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.
