Two issues to flag before I do anything:

1. **The times don't match.** 09:00 UTC is currently 02:00 US Pacific (PDT, UTC‑7). A hold at "09:00 US Pacific" would land at 16:00 UTC — seven hours after your standup. Which do you actually want?
   - Standup tracks 09:00 UTC → the Pacific hold should be 02:00 PT
   - Standup tracks 09:00 local Pacific → the meeting itself needs rescheduling, not just the hold

   Also note the offset shifts to UTC‑8 when US daylight saving ends (Nov 2, 2026), so a fixed-UTC standup will drift by an hour in a Pacific-time calendar.

2. **I don't have a calendar tool available** in this environment, so I can't create the event directly. I can draft an `.ics` file you can import, or give you the exact settings to enter manually.

Let me know the intended time and which you'd prefer.

Full harness trace — flagOn · seed 2

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
