A quick heads-up before I do anything: those two times don't line up. Right now (September, so US Pacific is on PDT = UTC‑7):

- **09:00 UTC** = **02:00 Pacific**
- **09:00 Pacific** = **16:00 UTC**

So a hold titled "Standup" at 09:00 Pacific would land 7 hours after the actual 09:00 UTC standup. Which do you actually want?

- Hold at **09:00 UTC / 02:00 Pacific** to match the real standup, or
- Hold at **09:00 Pacific / 16:00 UTC** as literally stated?

Also note: if you anchor the recurring event to Pacific time, it will shift relative to UTC when US daylight saving ends (Nov 2), so it'd be 17:00 UTC in winter. Anchoring to UTC keeps it aligned with a UTC-scheduled standup.

Separately, 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 plug into your calendar app — let me know which time you want and I'll put it together.

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.
