Function handle_muxspect_list 

pub async fn handle_muxspect_list(__arg0: State<AppState>) -> impl IntoResponse

GET /api/v1/muxspect/list — every controller-backed block’s current ProcessStatus, full detail (unlike agent.tracked-blocks, which intentionally returns only block_ids for its Swarm-pane contract). Each row also carries is_agent — ProcessStatus::is_agent()’s complete classification rule (subprocess/persistent/acp are ALWAYS agents regardless of is_agent_pane, which only applies to shell/cmd) — so consumers don’t reimplement that rule themselves (codex P2 on PR #2380: the CLI’s own naive is_agent_pane-only rendering mislabeled exactly those three controller types).
