For remote attendants: the draft agenda is in https://docs.google.com/spreadsheets/d/1FjBayj38Bu3FAUoZSi8LCY0NrkyXaTt4h9zUIT7ei2Y/edit?usp=sharing (it's not final, this session is currently planned to be 16:00 London time on April 15). If you have any comments, it would be easier to coordinate in the #collab-summit-london-2026 slack channel
