I'm getting concerned about the number of files we're adding to the repo here. I did approve the original design, but I thought the number of files would be lower, or more gradually added/removed.

Seeing this number of files, I think we should instead move to a single file arm-leases.yaml, with the same lease contents, just in a single file rather than 406 files. Or some other design that's easier to manage than 406 files in nested folders.

Based on the checks in this PR, these 409 lease files don't appear to be impacting checkout perf. So while I still think it would be better to refactor them into a single file, I'm fine with merging them as-is for now.

One error you will need to fix, prettier is failing because you have invalid yaml:

Reviewer name needs to be quoted. In the widget example, startdate is also quoted, but I'm not sure if that's necessary or optional.

Fix prettier errors in yaml files. At a minimum, reviewer names starting with "@" need to be quoted. We should also require trailing newlines -- i think prettier requires this by default, and it might flag after you quote the reviewer names.
