Join desktop hosts through sealed WebSockets using the shared Live Share protocol. Await remote operations without blocking the browser, keep ordered SQLite and OPFS writes durable before publication, and retain queued edits across reloads and reconnects.

Refresh shared section catalogs, arm watches when all sections are held, and distinguish device removal from a stopped share. Hosting and section organization remain on desktop.

Validated all CI lanes, browser approval/removal, bidirectional edits, offline reload/recovery, live section discovery, and a fresh OneNote 2010 cold-open of browser-written Unicode.
