## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Could not capture package-lock.json: source unavailable or larger than the capture limit. Open its source link to check setup.
> The intended package manager and version are not established by captured evidence.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
