A second /connect started a new poll loop without stopping the first. The first loop then polled with the new client too, so each message could be shown twice. It also read stopPoll without a.mu while cmdConnect wrote it. cmdConnect now closes the earlier loop's channel in the same locked step that replaces the client and the cursor, and hands the new channel to the new loop. The loop checks its channel under a.mu before each poll and again before it moves the cursor, so a stopped loop never polls with the new client or moves the new cursor. Model: opus-5-5
