+# FightRate RN — Continuous Monitoring + Training Windows
+
+## Objective
+Change FightRate so BLE heart-rate monitoring is continuous and locally persisted, while a workout/training session is only a marked time window inside that continuous stream. Starting a workout begins a highlighted window; stopping it closes that window and keeps monitoring alive.
+
+## Success Criteria
+- The native Android foreground service can start monitoring without creating a workout window.
+- Samples are saved continuously even when no workout window is active.
+- Start/stop workout only opens/closes a `workout_sessions` window; it does not stop BLE monitoring.
+- History lists saved windows and each item can be opened to inspect details from samples inside that window.
+- Insight and history screens use only real timestamped samples.
+- Capture/History/Insights UI removes generic card-heavy containers and uses Corner Instrument rails, strips, dividers, and instrument surfaces.
+- Existing bare React Native CLI constraint remains; no Expo.
+
+## Boundaries
+- No new dependencies unless unavoidable.
+- Do not delete existing tables destructively; migrate by adding a continuous sample table and deriving session summaries from timestamps.
+- Android physical BLE validation remains required after APK install.
+
+## Verification
+- `npm run typecheck`
+- `npm run lint`
+- `npm test -- --runInBand`
+- `npm audit --audit-level=moderate`
+- `cd FightRateRN/android && ./gradlew assembleRelease -PreactNativeArchitectures=arm64-v8a`
