In the session, It sees "Waiting for 3 background agents to finish" but it expects 4 to still be running.
"You're right, that was a miscount on my part. Fable had already finished before I launched the A0 agent, so only 3 were running concurrently at that point: Opus (player stats screen), Sonnet (TODO.md cleanup), and the new Sonnet (Phase A0). I'd added Fable back in by mistake. Thanks for catching it — still 3 running now."
