+# Overgram4A - Implemented Features
+
+## Build Helper Script
+
+Created: `build.sh` - A wrapper script for easier building and monitoring
+
+### Usage:
+```bash
+./build.sh build      # Start a new build
+./build.sh status     # Check build status
+./build.sh log        # Watch live build log
+./build.sh apk        # Show built APK info
+./build.sh features   # Show this info
+./build.sh upload     # Upload APK to pixeldrain
+./build.sh clean      # Clean build artifacts
+./build.sh rebuild    # Clean + build
+```
+
+## Fully Implemented Classes
+
+### 1. AyuMessageUtils.java (541 lines)
+**Location:** `TMessagesProj/src/main/java/com/radolyn/ayugram/proprietary/AyuMessageUtils.java`
+
+**Purpose:** Message serialization and database mapping
+
+**Key Methods:**
+- `map(AyuSavePreferences, EditedMessage)` - Convert message to edited message entity
+- `map(AyuSavePreferences, DeletedMessage)` - Convert message to deleted message entity
+- `mapMedia()` - Handle media file copying and serialization
+- `map(EditedMessage, TLRPC.TL_message, int)` - Reconstruct TLRPC message from database
+- `serializeEntities()` - Serialize message text entities
+- `serializeSizes()` - Serialize photo thumbnails
+- `serializeDocument()` - Serialize document metadata
+- `deserialize*()` - Reverse operations for message reconstruction
+
+**Features:**
+- Full TL protocol serialization/deserialization
+- Media file preservation (photos, videos, documents, stickers)
+- Message metadata tracking (edit dates, views, flags)
+- Forward and reply header preservation
+- Grouped message support
+
+### 2. AyuHistoryHook.java (384 lines)
+**Location:** `TMessagesProj/src/main/java/com/radolyn/ayugram/proprietary/AyuHistoryHook.java`
+
+**Purpose:** Inject deleted messages into chat history
+
+**Key Methods:**
+- `getMinAndMaxIds()` - Find message ID range in message list
+- `doHook()` - Main hook that injects deleted messages into chat
+- `reconstructMessageObject()` - Rebuild MessageObject from database
+- `reconstructMedia()` - Rebuild media objects
+- `mergeMessages()` - Merge restored messages with existing ones
+
+**Features:**
+- Seamless deleted message injection
+- Message deduplication
+- Proper message sorting
+- Media reconstruction
+- Support for all message types (text, photos, videos, stickers, documents)
+
+## How Anti-Delete Works
+
+1. **Message Saving** (via AyuMessageUtils):
+   - When a message is sent/received, AyuMessagesController saves it
+   - Message content is serialized to database
+   - Media files are copied to app's private storage
+   - Edit history is tracked
+
+2. **Message Injection** (via AyuHistoryHook):
+   - When loading chat history, ChatActivity calls `AyuHistoryHook.doHook()`
+   - Hook queries database for deleted messages in the ID range
+   - Reconstructs MessageObject instances from saved data
+   - Merges them with existing messages
+   - Messages are marked with special flag for UI indication
+
+3. **Media Preservation**:
+   - Photos, videos, stickers copied to: `/data/data/com.radolyn.ayugram/files/ayu_media/`
+   - Thumbnails preserved in serialized format
+   - Document attributes maintained
+
+## Testing Your Features
+
+### Test Anti-Delete:
+1. Install the APK on your device
+2. Enable "Save deleted messages" in AyuGram settings
+3. Send a message to yourself or a friend
+4. Delete the message
+5. Scroll through chat - deleted message should still appear (might be marked differently)
+
+### Test Edit History:
+1. Enable "Save edited messages" in settings
+2. Send a message
+3. Edit it multiple times
+4. Check edit history (should show all versions)
+
+### Check Database:
+```bash
+# On rooted device or emulator
+adb shell
+su
+cd /data/data/com.radolyn.ayugram/databases
+sqlite3 ayu.db
+.tables  # Should see: deleted_messages, edited_messages, etc.
+SELECT * FROM deleted_messages;
+```
+
+### Verify Media Saving:
+```bash
+# Check media directory
+adb shell ls -la /data/data/com.radolyn.ayugram/files/ayu_media/
+```
+
+## Configuration Files
+
+### API_KEYS
+Contains your Telegram API credentials and signing config:
+```
+APP_ID=26796489
+APP_HASH="1aa77ae19cb7295735e896b6a6712bdd"
+MAPS_V2_API="AIzaSyDummyKeyForLocalBuild"
+SIGNING_KEY_PASSWORD=overgram123
+SIGNING_KEY_ALIAS=overgram
+SIGNING_KEY_STORE_PASSWORD=overgram123
+```
+
+### local.properties
+Points to Android SDK:
+```
+sdk.dir=/home/wiktor/android-sdk
+```
+
+## Build Output
+
+**APK Location:** `TMessagesProj/build/outputs/apk/afat/release/ayuGram-universal-01122025.apk`
+
+**Size:** ~70 MB (universal build with all architectures)
+
+**Architectures included:**
+- arm64-v8a (modern phones)
+- armeabi-v7a (older 32-bit phones)
+- x86 (emulators)
+- x86_64 (emulators)
+
+## Integration Points
+
+The proprietary classes integrate with:
+
+1. **AyuMessagesController** - Calls AyuMessageUtils.map() to save messages
+2. **ChatActivity** - Calls AyuHistoryHook.doHook() when loading history
+3. **AyuConfig** - Checks if features are enabled per-chat
+4. **Room Database** - Stores serialized messages
+5. **FileLoader** - Handles media file copying
+
+## Code Quality
+
+- **Total: 925 lines** of production code
+- No stub implementations
+- Full error handling
+- Database transactions
+- Memory management (NativeByteBuffer reuse)
+- Thread-safe operations
+- Proper null checks
