Cool yeah I think it's definitely doable I just want to come up with a system that lets everything be verified as easily as possible.

If the process involves me having to download and sign an external ~300mb archive each time I push a new text file to the repo it'll discourage me from using it . A script that runs before git push'ing would be great.

Ideally, it would make index files that not only contain file size and file hash for everything in the archive - but are also linked up so the whole repository could be dropped onto a webhost (with directory listings disabled) and it would already be a navigatable basic website as well
