* Manages silent token refresh with rotation.
*
- * Handles:
- * - Automatic refresh before expiry (grace period)
- * - Token rotation (old refresh token is invalidated per rotation)
- * - Refresh failure handling (clears auth state, triggers re-authentication)
- * - Concurrent request deduplication (only one refresh at a time)
- * - Exponential backoff on refresh failures
+ * ## Responsibilities
*
- * Uses BuildConfig.API_BASE_URL for the API URL so it automatically
- * picks up debug/staging/production configuration.
+ * - **Automatic refresh before expiry** — Parses JWT `exp` claim and refreshes
+ * 5 minutes before expiry ([REFRESH_GRACE_PERIOD_MS]).
+ * - **Token rotation** — Stores the new refresh token if the backend rotates it.
+ * - **Concurrent deduplication** — Only one refresh runs at a time.
+ * - **Exponential backoff** — On transient failures, retries with jitter.
+ * - **Permanent failure** — After 3 failed attempts, clears auth state so the
+ * UI layer can show the login screen.
+ *
+ * ## Usage
+ *
+ * ```kotlin
+ * // Start periodic refresh on app startup
+ * tokenRefreshManager.startPeriodicRefresh()
+ *
+ * // Proactive refresh when app comes to foreground
+ * tokenRefreshManager.refreshIfNeeded()
+ * ```
+ *
+ * ## Thread Safety
+ *
+ * This class is designed to be called from both coroutine and blocking contexts.
+ * The core [refreshToken] is a suspend function. For OkHttp's [Authenticator],

+ *
+ * - **Connectivity Flow**: Exposes real-time network state as a [Flow] for UI consumption.
+ * - **SyncState Flow**: Combines connectivity + queue state + sync status into one UI-ready flow.
+ * - **Foreground Sync**: Processes the offline queue when the app comes to the foreground.
+ * - **Network Restoration**: Processes queue when network becomes available (existing behavior, enhanced).
+ * - **Offline Queue Count**: Exposes pending request count and per-entity counts for badges.
+ * - **WorkManager Lifecycle**: Respects app lifecycle for foreground queue processing.
+ *
* Design principles:
* - Periodic workers use flex intervals to allow batching by WorkManager
* - Constraints prevent sync during battery low or no connectivity

+## Notes
+
+- **Keystore**: If lost, you can still upload new versions with a new key, but existing users won't be able to update. Google Play App Signing mitigates this risk.
+- **Version codes**: Must be strictly increasing. Never reuse a versionCode.
+- **Processing time**: AAB processing can take 10-30 minutes after upload.
+- **Review time**: First-time app review can take up to 7 days. Subsequent updates are faster.
+- **Internal testing**: Fastest distribution method. Testers get immediate access after rollout.

+
+---
+
+## Prerequisites
+
+- Google account with Play Console access
+- $25 one-time developer registration fee paid
+- Signed AAB (Android App Bundle) ready to upload
+- App signing keystore generated (see [scripts/generate-release-key.sh](../scripts/generate-release-key.sh))
+- App assets prepared (icon, screenshots, feature graphic)
+- Privacy policy URL hosted and accessible
+- Firebase project linked to the app
+
+---
+
+## 1. Create the App
+
+1. Go to [Google Play Console](https://play.google.com/console)
+2. Click **"Create app"**
+3. Fill in:
+ - **App name**: `Kordant`
+ - **Default language**: `English (United States)`
+ - **App or game**: `App`
+ - **Free or paid**: `Free`
+4. Click **"Create app"**
+
+---
+
+## 2. App Signing
+
+### 2.1 Generate Upload Key
+
+```bash
+cd android
+chmod +x scripts/generate-release-key.sh
+./scripts/generate-release-key.sh
+```
+
+This creates:
+- `kordant-release.keystore` — The keystore file (KEEP SECURE)
+- `key.properties` — Credentials for Gradle (added to `.gitignore`)
+
+### 2.2 Configure Google Play App Signing
+
+1. Go to **Setup → App integrity → App signing**
+2. Select **"Let Google manage the app signing key"**
+3. Upload the upload certificate:
+ - Option A: Upload the `.keystore` file directly
+ - Option B: Extract the certificate and upload:
+ ```bash
+ keytool -export-cert \
+ -keystore kordant-release.keystore \
+ -alias kordant-release-key \
+ -file upload-cert.pem
+ ```
+ Then upload `upload-cert.pem`
+4. Review and accept the terms
+5. Click **"Enable"**
+
+### 2.3 Save the Backup Key
+
+After enabling Google Play App Signing, Google provides a **backup app signing key**. Download it and store it securely — this is your last resort if the upload key is lost.
+
+### 2.4 Verify Configuration
+
+After setup, note the **app signing key certificate fingerprint** (SHA-256). You'll need this for:
+- Firebase SHA-256 configuration (for Google Sign-In)
+- Facebook App configuration
+- Any other service requiring app identity verification
+
+---

+ ```
+3. Drag and drop the AAB file
+4. Wait for processing (can take several minutes)
+5. Fill in release notes
+6. Click **"Review release"** → **"Start rollout"**
+
+### 4.4 Verify Installation
+
+1. Each tester receives an email with the testing link

+
+## 9. Play Integrity API
+
+The app already includes Play Integrity integration via `PlayIntegrityManager`.
+
+### Enable in Play Console

+2. Ensure the API is enabled for your app
+3. Note: Play Integrity is automatically available for apps distributed through Google Play
+
+### Server-Side Verification
+Configure your backend to verify Play Integrity tokens:
+
+```bash
+# 1. Get Google's public keys
+# https://developer.android.com/google/play/integrity/verify
+
+# 2. Verify tokens using Google's verification library
+# Java: com.google.android.play:integrity:1.4.0
+# Or use Google Cloud Functions for verification
+```
+
+### Backend Integration
+The `PlayIntegrityManager` generates tokens that should be sent to your backend:
+1. App requests a nonce from your server
+2. Server passes nonce to `PlayIntegrityManager.requestIntegrityToken(nonce)`
+3. App sends the resulting token to your server
+4. Server verifies the token using Google's public keys
+5. Server checks `ctsProfileMatch` and `integrityResult` fields
+

+
+## Troubleshooting
+
+### "Upload key not found"
+Ensure `key.properties` exists and has correct paths:
+```bash
+cd android
+ls -la key.properties kordant-release.keystore
+```
+
+### "Build failed: signingConfig not found"
+The signing config is created dynamically from `key.properties`. Ensure the file exists and is valid.
+
+### "AAB upload rejected"
+Common causes:
+- Wrong target SDK (must be latest)
+- Missing required permissions declarations
+- App not properly signed
+- Version code conflicts (must be higher than previous release)
+
+### "Internal testers can't install"
+- Ensure testers accepted the invitation email
+- Wait up to 30 minutes for the release to process
+- Check that the AAB processed successfully in Play Console
+- Testers must use a Google account that matches the invited email
+
+### "Version code already used"
+Each release must have a unique, increasing `versionCode`. Update in `build.gradle.kts`:
+```kotlin
+defaultConfig {
+ versionCode = 2 // Increment from previous release
+ versionName = "1.1"
+}
+```

+# Android Build Scripts
+
+Scripts for building, signing, and distributing the Kordant Android app.
+
+## Scripts
+
+### `generate-release-key.sh`
+Generates a release keystore and configures signing for Google Play.
+
+```bash
+chmod +x scripts/generate-release-key.sh
+./scripts/generate-release-key.sh
+```
+
+Creates:
+- `kordant-release.keystore` — The keystore file (KEEP SECURE)
+- `key.properties` — Gradle signing credentials (in `.gitignore`)
+
+### `build-release-aab.sh`
+Builds a signed Android App Bundle (AAB) for Google Play upload.
+
+```bash
+chmod +x scripts/build-release-aab.sh
+./scripts/build-release-aab.sh # prodRelease (default)
+./scripts/build-release-aab.sh --variant=devRelease
+```
+
+Requires:
+- `key.properties` configured (copy from `key.properties.template`)
+- Android SDK configured in `local.properties`
+
+## Build Variants
+
+| Variant | Application ID | API URL | Use Case |
+|---------|---------------|---------|----------|
+| `prodRelease` | `com.kordant.android` | `api.kordant.com` | Google Play production |
+| `devRelease` | `com.kordant.android.dev` | `10.0.2.2:3000` | Internal testing |
+| `prodDebug` | `com.kordant.android.debug` | `api.kordant.com` | Debug with prod config |
+| `devDebug` | `com.kordant.android.dev.debug` | `10.0.2.2:3000` | Development |
+
+## Gradle Commands
+
+```bash
+# Build release AAB (for Play Store)
+./gradlew bundleProdRelease
+
+# Build release APK (for sideloading)
+./gradlew assembleProdRelease
+
+# Build debug APK
+./gradlew assembleDevDebug
+
+# Run unit tests
+./gradlew test
+
+# Run instrumentation tests (requires device/emulator)
+./gradlew connectedAndroidTest
+
+# Generate baseline profile (for startup optimization)
+./gradlew baselineProfileProdRelease
+
+# Clean build
+./gradlew clean
+```
+
+## Output Locations
+
+| Build Type | Output Path |
+|------------|-------------|
+| AAB | `app/build/outputs/bundle/prodRelease/app-prod-release.aab` |
+| APK | `app/build/outputs/apk/prod/release/app-prod-release.apk` |
+| Test APK | `app/build/outputs/apk/androidTest/prod/debug/app-prod-debug-androidTest.apk` |
+| ProGuard mapping | `app/build/outputs/mapping/prodRelease/mapping.txt` |
+| Baseline profile | `app/build/outputs/baselineProfiles/prodRelease/baseline-prof.txt` |
+
+## Signing
+
+The app uses Google Play App Signing. The upload key is managed via `key.properties`:
+
+1. Copy template: `cp key.properties.template key.properties`
+2. Edit with your credentials
+3. Build: `./gradlew bundleProdRelease`
+
+The `key.properties` file is in `.gitignore` and should NEVER be committed.
