An agent can now be watched by several observers at once

An agent's activity now goes to every connected observer, and one that connects mid-turn waits for the next turn

Unclear It is not clear which user-facing feature uses these observer pairings.

What

Claude Code can pair an agent with an observer that receives its activity. Before, only one pairing was looked up per agent. Now every active pairing gets the activity.

Each turn records which pairings were open when it started. A pairing that becomes active partway through a turn does not get that turn's opening activity.

Why

Several observers can follow the same agent, and one that joins late does not receive half of a turn.
