+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.

+# Mobile App Implementation Summary
+
+## Overview
+
+Implemented iOS and Android mobile apps using **Hotwire Native** as hybrid wrappers around the existing Symfony web app. The apps reuse 90%+ of the web codebase while having platform-specific billing (App Store for iOS, Play Store for Android, Stripe for web).
+
+## What Was Implemented
+
+### Phase 1: Platform Detection
+- **Platform enum** (`src/Value/Platform.php`) - Web/iOS/Android detection
+- **PlatformDetector service** - Detects platform from User-Agent header
+- **PlatformTwigExtension** - Twig functions `is_web()`, `is_ios()`, `is_android()`, `is_native_app()`
+- **JavaScript detection** in `app.js` - Sets `window.isNativeApp` and `window.nativePlatform`
+- **CSS classes** - `platform-web`, `platform-ios`, `platform-android`, `native-app`
+
+### Phase 2: Billing Infrastructure
+- **Database migration** - Added `platform` column to `membership` table
+- **Membership entity** - Added platform property and helper methods
+- **Billing interface** (`PlatformBillingInterface`) - Common contract for all platforms
+- **Platform billing services** - `WebStripeBilling`, `IosAppStoreBilling`, `AndroidPlayBilling`
+- **BillingFactory** - Returns appropriate service based on detected platform
+
+### Phase 3: Platform-Specific UI
+- **base.html.twig** - Header/footer wrapped in `{% if is_web() %}` conditionals
+- **membership.html.twig** - Platform-specific subscription buttons and management links
+- **Translations** - Added keys for all 6 languages (en, cs, de, es, fr, ja)
+
+### Phase 4: Native Scanner Bridge
+- **barcode_scanner_controller.js** - Added native bridge methods
+  - `window.onNativeScanResult(code)` callback
+  - `window.onNativeScanCancelled()` callback
+  - Auto-detects native app and uses native scanner instead of web camera
+
+### Phase 5: API Endpoints
+- `POST /api/ios/verify-receipt` - iOS App Store receipt verification
+- `POST /api/android/verify-purchase` - Android Play Store purchase verification
+
+### Phase 6: iOS App (`ios/`)
+- Swift Package Manager project with Hotwire Native iOS dependency
+- `WebViewController` with JavaScript bridges for scanner and billing
+- `BarcodeScannerBridge` - Native AVFoundation barcode scanner (EAN-8/EAN-13)
+- `StoreKitManager` - StoreKit 2 in-app purchases
+- `BillingBridge` - JavaScript bridge for purchases
+
+### Phase 7: Android App (`android/`)
+- Gradle project with Hotwire Turbo Android dependency
+- `TurboWebFragment` with JavaScript interfaces
+- `BarcodeScannerBridge` - CameraX + ML Kit barcode scanner
+- `BillingManager` - Google Play Billing Library integration
+- Material Design UI with scan overlay
+
+### Phase 8: CI/CD
+- `.github/workflows/ios.yml` - Builds on macOS, runs tests
+- `.github/workflows/android.yml` - Builds APK, uploads artifacts
+
+## Problems Faced & Solutions
+
+### 1. PHPStan Error with `is_array()` Check
+**Problem:** PHPStan complained that `is_array()` always evaluates to true when a `@var` annotation was placed before `json_decode()`.
+
+**Solution:** Moved the `@var` annotation to after the `is_array()` check:
+```php
+// Before (error)
+/** @var array<string, mixed> $data */
+$data = json_decode($content, true);
+
+// After (fixed)
+$data = json_decode($content, true);
+if (!is_array($data)) { return error; }
+/** @var array<string, mixed> $data */
+```
+
+### 2. Duplicate Companion Object in Kotlin
+**Problem:** Android `BarcodeScannerBridge.kt` had two `companion object` declarations.
+
+**Solution:** Consolidated all constants into a single companion object at the bottom of the class.
+
+### 3. Turbo Globally Disabled
+**Problem:** Turbo is disabled via `data-turbo="false"` on `<html>` element.
+
+**Solution:** This is intentional per project architecture. Native apps use Hotwire Native which handles navigation natively, so Turbo being disabled doesn't affect mobile apps.

+
+## Next Steps
+
+### Immediate (Required for Launch)
+1. **Run migration:** `docker compose exec web php bin/console doctrine:migrations:migrate`
+2. **Implement actual receipt verification** in `IosAppStoreBilling` and `AndroidPlayBilling` (currently stubs)
+3. **Set up App Store Connect:** Create app, configure in-app purchase products
+4. **Set up Google Play Console:** Create app, configure subscription products
+
+### For Production Deployment
+5. **Code signing:**
+   - iOS: Add certificates and provisioning profiles to GitHub secrets
+   - Android: Create and secure signing keystore
+6. **App icons and launch screens** for both platforms
+7. **Webhook endpoints** for subscription status updates from Apple/Google
+8. **TestFlight/Internal testing** before public release
+
+### Product IDs
+- **iOS:** `com.myspeedpuzzling.premium.monthly`, `com.myspeedpuzzling.premium.yearly`
+- **Android:** `premium_monthly`, `premium_yearly`
+
+## Testing
+
+The web app continues to work normally. All PHP checks pass:
+- PHPStan: ✅
+- PHPCS: ✅
+- PHPUnit: ✅
+- Schema validation: ✅
+- Cache warmup: ✅
+
+Native apps are isolated in `ios/` and `android/` directories and cannot break the web app.
