@codysoyland this is a PR against your branch which should get most of your CI checks ✅

There are a few failing checks still that I didn't address cause I thought you might want to look at them:

• There's a naming thing (LogId vs LogID) that the linter picked-up
• The codegen verifier is complaining about some diffs that I wasn't sure how to handle

Unfortunately you can't see it in this PR, but all of the e2e tests are passing now (those workflows only run on PRs against main so they weren't executed here -- you can see them passing here)
