## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Some entry points named in the manifest are build output or are missing from the file list, so their source is not shown.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
