Can you push the Tuesday meeting an hour later?
final reply
I don't have access to a calendar, email, or scheduling tool in this environment—only file access in the `/tmp` workspace and the ability to fetch URLs. So I can't reschedule the meeting myself.

If you have meeting details stored in a file here, I can help edit those. Otherwise, you'll need to update the event in your calendar app directly (and notify attendees). If you tell me which meeting it is, I can also draft a quick message to the participants letting them know about the new time.
