Quick flag before I create anything: those two times don't match. Your standup is 09:00 UTC, but 09:00 US Pacific is 16:00 UTC (17:00 UTC in winter, since Pacific shifts between PDT and PST). Conversely, 09:00 UTC is only 02:00 Pacific right now.

Which do you actually want the hold at?
- **09:00 UTC** (matches the standup) → 02:00 US/Pacific
- **09:00 US/Pacific** (as literally requested) → 16:00–17:00 UTC, i.e. not during the standup

Also worth deciding: should the event be pinned to a fixed UTC time, or to Pacific wall-clock time (which will drift ±1h against UTC across DST changes)?

Let me know and I'll set it up. (Note: I don't see a calendar tool wired up in this environment, so I may only be able to draft an .ics file for you to import.)

Full harness trace — contradictionOff · 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.
