Quick conflict to sort out first: your standup is at 09:00 UTC, but 09:00 US Pacific is a different time. On today's date (PDT, UTC‑7), 09:00 UTC = 02:00 Pacific, and 09:00 Pacific = 16:00 UTC. Note Pacific also shifts to PST (UTC‑8) in winter, so a Pacific-anchored hold would drift relative to the UTC standup across DST changes.

Which do you want?
1. A hold at 09:00 UTC (matches the actual standup; shows as 02:00/01:00 Pacific depending on DST)
2. A hold fixed at 09:00 US Pacific time (16:00 or 17:00 UTC — does not match the 09:00 UTC standup)

Also, what recurrence — every weekday, or daily including weekends? And do you have a preferred calendar tool/account you want this added to (I don't see a calendar integration available here)?

Full harness trace — flagOn · seed 1

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.
