How This Pair Actually Operates

Curitiba 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.

Operating mode
Handoff-led

Live meetings are the exception path here. The operational default should be a documented handoff with a clearly named next owner.`

Meeting cadence
