Currently, it's hard to figure out what's happening in the browser with respect to real-time infrastructure. Pertinent information is spread across multiple tabs (when it's present at all) and difficult to decipher.

The major components to monitor are:

• Cross-tab sync through Local Storage (JX.Leader).
• The uplink to Aphlict (JX.Aphlict)
• Messages over both channels (notifications, commands).
• State changes on both channels (connect, disconnect, reconnect, promote, usurp).

Some explicit client actions are not easy to trigger in a diagnostic way:

• Force disconnect.
• Force reconnect.
• Force UI state dirty (after T12566).
• Force message replay (for T12564).
• Force promote/usurp for JX.Leader.

Probably the best way to approach this is a DarkConsole "Realtime" tab.
