+# Add durable status milestones and optional Pi-native status UI
+
+## Question
+
+Connect the public status model to durable milestone entries and an optional Pi-native status UI without making the UI required for status or result retrieval.
+
+## What to build
+
+Add the presentation layer around the existing status data model.
+The extension should append durable lifecycle milestones, show a collapsed live summary by default, offer an expanded inspector, and keep the UI replaceable by another extension.
+Disabling the bundled UI should not disable status records, status events, or tools.
+
+## Acceptance criteria
+
+- [ ] Spawn accepted, completed, failed, cancelled, and timed-out milestones are appended as durable entries.
+- [ ] Milestone entries do not inject child transcripts into normal LLM context.
+- [ ] The collapsed UI summary shows live counts.
+- [ ] The expanded inspector shows child id, label, context, state, elapsed time, model, tools, last event, and result availability.
+- [ ] Disabling `ui` hides bundled UI components but leaves list, status, result, and cancel tools working.
+
+## Implementation Notes
+
+Use the status data model as the source of truth.
+Do not stream every child event into the parent transcript.
