+# Pi subagent compact and expanded monitor
+
+## Question
+
+Implement the approved compact and expanded Pi-native subagent monitor behavior.
+
+## What to build
+
+The existing subagent widget should become the approved monitor.
+Compact mode should show aggregate counts by status rather than one row per child.
+Expanded mode should show one row per visible child with label, lifecycle state, elapsed time, and last activity or result marker.
+The monitor should make running, queued, settling, completed, failed, timed-out, and cancelled work distinguishable without requiring a blocking wait or JSON notification dump.
+
+## Acceptance criteria
+
+- [x] Compact mode shows aggregate counts by meaningful status groups.
+- [x] Expanded mode shows one row per child with label, state, elapsed time, and last activity or result marker.
+- [x] Rows truncate cleanly to terminal width.
+- [x] Failed, timed-out, cancelled, completed-with-result, running, queued, and settling children are visually distinguishable.
+- [x] The existing UI toggle still works.
+- [x] Tests cover compact and expanded rendering.
+
+## Implementation Notes
+
+Keep compact mode ambient.
+Do not make it a transcript or result preview surface.
+
+Implemented on branch `subagent-labels` in commit `aafc68e feat(pi): render subagent monitor views`.
+Compact rendering now aggregates visible children into queued, running, settling, completed, failed, timed out, cancelled, and orphaned groups.
+Expanded rendering now emits one truncated row per visible child with an icon, state, elapsed time, label, and activity/result/error marker.
+Verification passed with `nix shell nixpkgs#nodejs_24 nixpkgs#tsx -c tsx --test modules/agents/pi/extensions/subagents/ui.test.ts modules/agents/pi/extensions/subagents/supervisor.test.ts modules/agents/pi/extensions/subagents/runner.test.ts modules/agents/pi/extensions/subagents/config.test.ts`.
+Review found no blocking findings.
+The independent test-writer subagent was read-only, so the implementation agent authored the final tests after recording the blocked TDD attempt.
