How to set up and validate locally

Steps to reproduce

1. Create the folder structure above:
   • In the first commit, add the alpha folder and it's contents, and set the commit message to "alpha".
   • In the first commit, add the beta folder and it's contents, and set the commit message to "beta".
2. Open the "beta" folder and observe that all the files in this folder have the "beta" commit message and timestamps.
3. Using the breadcrumbs, navigate to the parent folder and then click into the "alpha" folder.
4. At this point, the files in the "alpha" folder will show "beta" as the commit message along with the beta timestamps, with the exception of the "alpha" file.
5. If you then refresh the page, the "alpha" files will then show the correct "alpha" commit message and timestamps.
