+# Dashboard Test Runner
+
+Status: active
+
+## Goal
+Provide an opt-in, admin-only tracker Dashboard Testing tab that dynamically discovers pytest tests, runs fixed collected targets safely in background, and reports live logs/status.
+
+## Safety
+- Disabled unless tracker starts with an explicit flag.
+- Admin-only API/UI.
+- No arbitrary command/argument execution.
+- One active run.
+- Real inference stays separately environment-gated and excluded from default suites.
+
+See `prd.json` for executable Ralph user stories and acceptance criteria.
