What happens if there’s a regression in coverage, maybe due to a large sweeping change, and you go from 0.40 -> 0.35 ?

There's the commit hash. Basically the "version number" is the commit hash, the human-generated (version) numbers added to it are merely progress indicators, which might be randomly useful. But for a project that has 1 branch, 0 tags and nearly 2000 commits, that's not really important.

yes, the entire exercise isn’t important. It just breaks the monotonicity that version numbers typically have. At that point, just call your version <progress>.sha
