+# Ente Log Viewer
+
+A web-based log viewer for analyzing Ente application logs. This tool provides similar functionality to the mobile log viewer, allowing you to upload, filter, and analyze log files from customer support requests.
+
+## Features
+
+### 📁 File Upload
+- Drag and drop ZIP files containing log files
+- Automatic extraction and parsing of log files
+- Support for daily log files format (YYYY-M-D.log)
+
+### 🔍 Search and Filtering
+- **Text Search**: Search through log messages, logger names, and error content
+- **Logger Filtering**: Use `logger:ServiceName` syntax to filter by specific loggers
+- **Wildcard Support**: Use `logger:Auth*` to match all loggers starting with "Auth"
+- **Level Filtering**: Filter by log levels (SEVERE, WARNING, INFO, etc.)
+- **Process Filtering**: Filter by foreground/background processes
+- **Timeline Filtering**: Filter by date/time ranges
+
+### 📊 Analytics
+- Logger statistics showing most active components
+- Log level distribution charts
+- Click-to-filter from analytics charts
+
+### 🎨 UI Features
+- **Color-coded log levels**: Red for SEVERE, orange for WARNING, etc.
+- **Process indicators**: Visual distinction between foreground and background processes
+- **Active filter chips**: Visual indication of applied filters with easy removal
+- **Log detail view**: Click any log entry for detailed information
+- **Sort options**: Sort by newest first or oldest first
+- **Responsive design**: Works on desktop and mobile devices
+
+### 📤 Export
+- Export filtered logs as text files
+- Copy individual log entries to clipboard
+- Maintain original formatting and error details
+
+## Usage
+
+### Starting the Application
+
+1. **Local Development**:
+   ```bash
+   cd infra/experiments/logs-viewer
+   python3 -m http.server 8080
+   ```
+   Open http://localhost:8080 in your browser
+
+2. **Upload Log Files**:
+   - Drag and drop a ZIP file containing `.log` files
+   - Or click "Choose ZIP File" to browse for files
+
+### Log Format Support
+
+The viewer understands the Ente log format as generated by `super_logging.dart`:
+
+```
+[process] [loggerName] [LEVEL] [timestamp] message
+```
+
+**Examples**:
+- `[bg] [SyncService] [INFO] [2025-08-24 01:36:03.677678] Syncing started`
+- `[CollectionsService] [WARNING] [2025-08-24 01:36:04.123456] Connection failed`
+
+**Multi-line Error Support**:
+- Automatically parses `⤷` error detail lines
+- Extracts stack traces and error IDs
+- Handles inline error messages and exceptions
+
+### Filtering Examples
+
+- **Search by text**: `connection failed`
+- **Filter by logger**: `logger:SyncService`
+- **Multiple loggers**: `logger:Sync* logger:Collection*`
+- **Combined search**: `logger:Auth* login failed`
+
+### Keyboard Shortcuts
+
+- **Search**: Click search bar or start typing
+- **Clear search**: Click X button or clear the input
+- **Sort toggle**: Click sort arrow button
+- **Filter dialog**: Click filter button
+
+## Technical Details
+
+### Supported Log Levels
+- **SHOUT**: Purple - Highest priority
+- **SEVERE**: Red - Errors and exceptions
+- **WARNING**: Orange - Warning conditions
+- **INFO**: Blue - Informational messages
+- **CONFIG**: Green - Configuration messages
+- **FINE/FINER/FINEST**: Gray - Debug messages
+
+### Process Types
+- **Foreground**: Main app processes
+- **Background (bg)**: Background tasks
+- **Firebase Background (fbg)**: Firebase-related background processes
+
+### Performance
+- Lazy loading: Only renders visible log entries
+- Efficient filtering: Client-side filtering with optimized algorithms
+- Memory management: Handles large log files (tested with 100k+ entries)
+
+## Sample Log Files
+
+For testing, you can use any ZIP file containing `.log` files from Ente mobile app logs.
+
+## Development
+
+### File Structure
+```
+logs-viewer/
+├── index.html          # Main HTML structure
+├── styles.css          # CSS styling
+├── script.js           # JavaScript logic
+├── README.md           # This documentation
+└── references/         # UI reference screenshots
+```
+
+### Key JavaScript Classes
+- `LogViewer`: Main application class
+- Log parsing logic in `parseLogFile()` and `parseLogLine()`
+- Filter management in `applyCurrentFilter()`
+- UI rendering in `renderLogs()` and `createLogEntryHTML()`
+
+### Adding Features
+1. **New Filter Types**: Extend `currentFilter` object and `matchesFilter()` method
+2. **New Log Formats**: Update parsing patterns in `parseLogLine()`
+3. **UI Components**: Add HTML elements and CSS classes, wire up in `initializeEventListeners()`
+
+## Troubleshooting
+
+### Common Issues
+
+1. **ZIP file not loading**:
+   - Ensure ZIP contains `.log` files
+   - Check browser console for errors
+   - Try a smaller file first
+
+2. **Logs not parsing correctly**:
+   - Check log format matches expected pattern
+   - Look for console warnings about parsing failures
+   - Verify timestamp format is correct
+
+3. **Performance issues with large files**:
+   - The viewer handles pagination (100 logs at a time)
+   - Use filters to reduce the dataset
+   - Close other browser tabs to free memory
+
+4. **Search not working**:
+   - Check for typos in logger names
+   - Use wildcard syntax: `logger:Service*`
+   - Search is case-insensitive for message content
+
+### Browser Compatibility
+- **Recommended**: Chrome 80+, Firefox 75+, Safari 13+
+- **Required**: ES6 support, Fetch API, File API
+- **Dependencies**: JSZip library for ZIP file handling
+
+## Future Enhancements
+
+- Real-time log streaming
+- Advanced regex search
+- Log correlation and grouping
+- Performance metrics dashboard
+- Dark theme support
+- Export to JSON/CSV formats

+# CLAUDE.md
+
+This file provides guidance to Claude, Codex, and any other agent when working with code in this repository.
+
+## Project Philosophy
+
+Ente is focused on privacy, transparency and trust. It's a fully open-source, end-to-end encrypted platform for storing data in the cloud. When contributing, always prioritize:
+- User privacy and data security
+- End-to-end encryption integrity
+- Transparent, auditable code
+- Zero-knowledge architecture principles
+
+## Monorepo Context
+
+This is the Ente Photos mobile app within the Ente monorepo. The monorepo contains:
+- Mobile apps (Photos, Auth, Locker) at `mobile/apps/`
+- Shared packages at `mobile/packages/`
+- Web, desktop, CLI, and server components in parent directories
+
+### Package Architecture
+The Photos app uses two types of packages:
+- **Shared packages** (`../../packages/`): Common code shared across multiple Ente apps (Photos, Auth, Locker)
+- **Photos-specific plugins** (`./plugins/`): Custom Flutter plugins specific to Photos app for separation and testability
+
+## Commit & PR Guidelines
+
+⚠️ **CRITICAL: From the default template, use ONLY: Co-Authored-By: Claude <noreply@anthropic.com>** ⚠️
+
+### Pre-commit/PR Checklist (RUN BEFORE EVERY COMMIT OR PR!)
+
+**CRITICAL: CI will fail if ANY of these checks fail. Run ALL commands and ensure they ALL pass.**
+
+```bash
+# 1. Format Dart code
+dart format .
+
+# 2. Analyze flutter code for errors and warnings
+flutter analyze
+```
+
+**Why CI might fail even after running these:**
+
+- Skipping any command above
+- Assuming auto-fix tools handle everything (they don't)
+- Not fixing warnings that flutter reports
+- Making changes after running the checks
+
+### Commit & PR Message Rules
+
+**These rules apply to BOTH commit messages AND pull request descriptions**
+
+- Keep messages CONCISE (no walls of text)
+- Subject line under 72 chars (no body text unless critical)
+- NO emojis
+- NO promotional text or links (except Co-Authored-By line)
+
+### Additional Guidelines
+
+- Check `git status` before committing to avoid adding temporary/binary files
+- Never commit to main branch
+- All CI checks must pass - run the checklist commands above before committing or creating PR
+
+## Development Commands
+
+### Using Melos (Monorepo Management)
+```bash
+# From mobile/ directory - bootstrap all packages
+melos bootstrap
+
+# Run Photos app specifically
+melos run:photos:apk
+
+# Build Photos APK
+melos build:photos:apk
+
+# Clean Photos app
+melos clean:photos
+```
+
+### Direct Flutter Commands
+```bash
+# Development run with environment variables
+./run.sh                                    # Uses .env file with --flavor dev
+
+# Development run without env file
+flutter run -t lib/main.dart --flavor independent
+
+# Build release APK
+flutter build apk --release --flavor independent
+
+# iOS build
+cd ios && pod install && cd ..
+flutter build ios
+```
+
+### Code Quality
+```bash
+# Static analysis and linting
+flutter analyze .
+
+# Run tests
+flutter test
+```
+
+## Architecture Overview
+
+### Service-Oriented Architecture
+The app uses a service layer pattern with 28+ specialized services:
+- **collections_service.dart**: Album and collection management
+- **search_service.dart**: Search functionality with ML support
+- **smart_memories_service.dart**: AI-powered memory curation
+- **sync_service.dart**: Local/remote synchronization
+- **Machine Learning Services**: Face recognition, semantic search, similar images
+
+### Key Patterns
+- **Service Locator**: Dependency injection via `lib/service_locator.dart`
+- **Event Bus**: Loose coupling via `lib/core/event_bus.dart`
+- **Repository Pattern**: Database abstraction in `lib/db/`
+- **Rust Integration**: Performance-critical operations via Flutter Rust Bridge
+
+### Security Architecture
+- End-to-end encryption with `ente_crypto` package
+- BIP39 mnemonic-based key generation (24 words)
+- Secure storage using platform-specific implementations
+- App lock and privacy screen features
+

+└── generated/     # Auto-generated code including localizations
+```
+
+## Localization (Flutter)
+
+- Add new strings to `lib/l10n/intl_en.arb` (English base file)
+- Use `AppLocalizations` to access localized strings in code
+- Example: `AppLocalizations.of(context).yourStringKey`
+- Run code generation after adding new strings: `flutter pub get`
+- Translations managed via Crowdin for other languages
+
+## Key Dependencies
+
+- **Flutter 3.32.8** with Dart SDK >=3.3.0 <4.0.0
+- **Media**: `photo_manager`, `video_editor`, `ffmpeg_kit_flutter`
+- **Storage**: `sqlite_async`, `flutter_secure_storage`
+- **ML/AI**: Custom ONNX runtime, `ml_linalg`
+- **Rust**: Flutter Rust Bridge for performance
+
+## Development Setup Requirements
+
+1. Install Flutter v3.32.8 and Rust
+2. Install Flutter Rust Bridge: `cargo install flutter_rust_bridge_codegen`
+3. Generate Rust bindings: `flutter_rust_bridge_codegen generate`
+4. Update submodules: `git submodule update --init --recursive`
+5. Enable git hooks: `git config core.hooksPath hooks`
+
+## Critical Coding Requirements
+
+### 1. Code Quality - MANDATORY
+**Every code change MUST pass `dart format .` and `flutter analyze` with zero issues**
+- Run `dart format .` first to format all Dart code
+- Run `flutter analyze` after EVERY code modification
+- Resolve ALL issues (info, warning, error) - no exceptions
+- The codebase has zero issues by default, so any issue is from your changes
+- DO NOT commit or consider work complete until both commands pass cleanly
+
+### 2. Component Reuse - MANDATORY
+**Always try to reuse existing components**
+- Use a subagent to search for existing components before creating new ones
+- Only create new components if none exist that meet the requirements
+- Check both UI components in `lib/ui/` and shared components in `../../packages/`
+
+### 3. Design System - MANDATORY
+**Never hardcode colors or text styles**
+- Always use the Ente design system for colors and typography
+- Use a subagent to find the appropriate design tokens
+- Access colors via theme: `getEnteColorScheme(context)`
+- Access text styles via theme: `getEnteTextTheme(context)`
+- Call above theme getters only at the top of (`build`) methods and re-use them throughout the component
+- If you MUST use custom colors/styles (extremely rare), explicitly inform the user with a clear warning
+
+### 4. Documentation Sync - MANDATORY
+**Keep spec documents synchronized with code changes**
+- When modifying code, also update any associated spec documents
+- Check for related spec files in `docs/` or project directories
+- Ensure documentation reflects the current implementation
+- Update examples in specs if behavior changes
+
+### 5. Database Methods - BEST PRACTICE
+**Prioritize readability in database methods**
+- For small result sets (e.g., 1-2 stale entries), prefer filtering in Dart for cleaner, more readable code
+- For large datasets, use SQL WHERE clauses for performance - they're much more efficient in SQLite
+
+## Important Notes
+
+- Large service files (some 70k+ lines) - consider file context when editing
+- 400+ dependencies - check existing libraries before adding new ones
+- When adding functionality, check both `../../packages/` for shared code and `./plugins/` for Photos-specific plugins
+- Performance-critical paths use Rust integration
+- Always follow existing code conventions and patterns in neighboring files
