How This Pair Actually Operates
St Louis and Tehran only have a thin live relay window, so most progress depends on explicit ownership transfer rather than long meetings.
Use live overlap for escalations and approvals, then hand work across the day boundary with clear next-seen expectations.
Live meetings are the exception path here. The operational default should be a documented handoff with a clearly named next owner.`
Use a small escalation slot and treat the rest of the operating model as async handoff-driven.
