## About the role

Plane's client is local-first and collaborative, which means state lives in the browser, moves over WebSockets to an Elixir sync service, survives the network going away, and has to resolve what happens when two people edit the same document at once. Agents now edit alongside those people, so the same client has to make a machine's change as legible and as attributable as a colleague's.
