The .git folder does not seem to be present on Heroku CI Dynos
I can attach to the dyno as per https://devcenter.heroku.com/articles/heroku-ci#debugging
$ heroku ci:debug --pipeline
Preparing source... done
Creating test run... done
Running setup and attaching to test dyno...
~ $ pwd
/app
~ $ cd .git
bash: cd: .git: No such file or directory
But I want to run tooling that requires the .git folder to be present to compare shas and files.
