GitHub has a handy keyboard shortcut I use all the time: on any page with a ref in the URL, you can press "y" and it canonicalizes the URL.
E.g.:
https://tangled.org/mitchellh.com/test/blob/main/.tangled/workflows/test.yml
would replace "mitchellh.com" with the did and "main" with the SHA (and maybe "test" with the did in the future too).
Its very good for sharing permalinks with people.
