What PR is the canonical source of truth for all audit fixes?

Unfortunately there is no single canonical PR for the audit fixes. I'd say the closest thing is the original set of nine PRs that I made in the optimism-audit-fixes repo here. You can also check the diff of this mega PR which contains those nine PRs merged together. However, that PR has some minor mistakes from merge conflicts and hasn't been reviewed thoroughly, so I wouldn't call it canonical.
