How This Pair Actually Operates
Reykjavik and Shanghai 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.
Best Async Lane Right Now
Shanghai → Reykjavik
Shanghai → Reykjavik is the faster handoff lane right now. Expected first seen: Mon, Aug 31 · 16:04. Expected action: Mon, Aug 31 · 16:29.

Reykjavik is inside a strong focus block, so fast acknowledgement is realistic.
