DOT Token Use

I can’t seem to find a clear answer on these questions. Any help is appreciated… Does Dot checking a codex task's status consume any of the shared Codex/Work token allowance? Does Dot independently checking that status consume its own deeper-work allowance? Does notifying you of completion trigger any additional usage? It’s not quite clear to me on when DOTwould use its own internal allowance versus when DOT would use the Codex/ChatGPT Work allowance?
