List of ToDo-ish Comments

We've accumulated a rather respectable list of `TODO`, `FIXME`, and `BAD CONSTANT` flags in the code.

To keep a tab on it, I've created a [Confluence page](https://eagles-project.atlassian.net/wiki/x/AQAOc) (apologies if any non-team-members cannot access--please reach out if that's you and you're stoked on squashing this issue).
