-# Agent Guide: Tijd Voor De Test (Tvdt)
-
-This document provides essential context and instructions for AI agents working on the **Tijd Voor De Test** project.
-
-## Project Overview
-A web application for managing "Wie is de Mol?" style tests, including seasons, quizzes, candidates, and eliminations.
-
- **Namespace**: `Tvdt`
- **PHP Version**: 8.5+
- **Framework**: Symfony 8.0
-
-## Tech Stack
- **Server**: FrankenPHP (Caddy-based PHP server)
- **Database**: PostgreSQL
- **Frontend**: Symfony Asset Mapper (no Node.js/Webpack), Stimulus, Turbo
- **Styling**: Sass (via `symfonycasts/sass-bundle`)
- **Persistence**: Doctrine ORM 3.x
-
-## Core Domain Entities
- **Season**: Groups quizzes and candidates for a specific period.
- **SeasonSettings**: Configuration for a season.
- **Quiz**: A test within a season containing multiple questions.
- **Question**: Questions belonging to a quiz.
- **Answer**: Possible answers for a question.
- **Candidate**: A participant in the season.
- **QuizCandidate**: Represents a candidate's attempt at a specific quiz (tracking start/end time).
- **GivenAnswer**: The specific answer a candidate selected during a quiz.
- **Elimination**: Records of red/green screens and forced results.
- **User**: Administrative accounts for managing the system.
-
-## Development Workflow
-The project uses `just` as the primary task runner. Always prefer `just` commands over manual docker calls.
-
-### Common Commands
- `just up`: Start the environment.
- `just down`: Stop the environment.
- `just shell`: Enter the PHP container.
- `just migrate`: Run database migrations.
- `just fixtures`: Load development fixtures.
- `just fix-cs`: Run `php-cs-fixer` and `twig-cs-fixer`.
- `just phpstan`: Run static analysis.
- `just rector`: Run Rector for automated refactorings.
- `just reload-tests`: Reset the test database and load test fixtures.
-
-## Coding Standards
- **PSR-12**: Follow standard PHP coding styles.
- **Strict Typing**: Use strict types in all PHP files.
- **Doctrine ORM 3**: Be aware of ORM 3 changes (e.g., lazy loading behavior, attribute-based mapping).
- **Symfony 8**: Use modern Symfony features (Attributes, Type-hinting).
- **Safe Functions**: Use `thecodingmachine/safe` for standard PHP functions that throw exceptions instead of returning false.
-
-## Testing
- **Framework**: PHPUnit
- **Bundle**: `dama/doctrine-test-bundle` is used to wrap tests in transactions.
- **Location**: `tests/` directory mirroring `src/`.
- **Execution**: Run via `bin/phpunit` inside the container or `just reload-tests` to prepare the environment.
-
-## Frontend Development
- JavaScript is managed via **Import Maps**.
- Stimulus controllers are located in `assets/controllers/`.
- CSS/Sass is in `assets/styles/`.
- Assets are compiled on-the-fly or mapped; do not look for a `node_modules` folder.
-
-## Key Components
-### Controllers
- **Backoffice**: Located in `src/Controller/Backoffice`, handles season and quiz management.
- **Quiz**: `src/Controller/QuizController` handles the candidate-facing side of quizzes.
- **Elimination**: `src/Controller/EliminationController` handles elimination screens.
-
-### Services
- **QuizSpreadsheetService**: Handles importing quizzes from XLSX files.
-
-### Base Classes & Enums
- **AbstractController**: Base class for all controllers, containing common regexes and flash helpers.
- **FlashType Enum**: Used for consistent flash messaging (`FlashType::Success`, `FlashType::Danger`, etc.).
-
-## Key Files
- `composer.json`: Dependency management.
- `importmap.php`: JavaScript module mapping.
- `Justfile`: Automation shortcuts.
- `config/`: Application configuration.
- `templates/`: Twig templates.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+**Tijd voor de test** is a PHP/Symfony 8.1 application for managing quizzes in the style of **Wie is de Mol?** (WIDM) — a Dutch TV show where contestants try to identify a saboteur ("de Mol") among them. At the end of each episode, participants take a quiz about the Mol's identity and actions; the candidate with the least correct answers is eliminated. This app replicates that quiz format with:
+- Test creation with variable question counts
+- Season management with active test controls
+- Candidate answer tracking with automatic timing
+- Elimination tracking with joker adjustments
+- Backoffice management for quiz administration and statistics
+
+Tech Stack:
+- **Framework**: Symfony 8.1
+- **PHP**: 8.5+
+- **Database**: PostgreSQL 16
+- **ORM**: Doctrine
+- **Server**: FrankenPHP with Caddy
+- **Container**: Docker Compose
+- **Frontend**: Twig templates with SASS (via asset mapper)
+- **Testing**: PHPUnit 13 with DAMA Doctrine test bundle
+
+## Build & Development Commands
+
+All commands assume Docker is running. The project uses a [Justfile](https://just.systems) as the primary interface.
+
+### Essential Commands
+
+```bash
+just up           # Start Docker services (PHP, PostgreSQL)
+just stop         # Stop services
+just down         # Stop and remove containers/orphans
+just shell        # Interactive shell inside the PHP container
+just shell-run    # Shell in a fresh one-off container
+```
+
+### Database
+
+```bash
+just migrate                  # Run Doctrine migrations (starts services first)
+just fixtures                 # Load dev fixtures (truncates first)
+just reload-tests             # Drop/recreate test DB, migrate, load test fixtures
+```
+
+### Testing
+
+```bash
+just test                                  # Run full PHPUnit suite
+just test tests/Path/To/TestFile.php       # Run a specific test file
+just test --coverage-html var/coverage     # Generate HTML coverage report
+```
+
+### Code Quality & Linting
+
+```bash
+just fix-cs                        # Auto-fix PHP-CS-Fixer + Twig-CS-Fixer
+just phpstan                       # PHPStan static analysis (level 9)
+just phpstan --no-progress         # Without progress output
+just rector                        # Apply Rector modernizations
+just rector --dry-run              # Preview Rector changes
+```
+
+### Other
+
+```bash
+just translations   # Extract/update nl translation strings
+just clean          # Nuke containers (volumes) + all generated files (prompts for confirmation)
+just trust-cert     # Trust the local Caddy TLS certificate (macOS)
+just exec <cmd>     # Run any command inside the PHP container
+```
+
+All code quality checks run in CI/CD (.github/workflows/ci.yml) and should pass before merging.

+
+## Core Domain Entities
+
+- **Season**: Groups quizzes and candidates for a specific period, with a linked `SeasonSettings`.
+- **Quiz**: A test within a season containing multiple `Question`s, each with multiple `Answer`s.
+- **Candidate**: A participant in the season.
+- **QuizCandidate**: Represents a candidate's attempt at a specific quiz (tracks start/end time).
+- **GivenAnswer**: The specific answer a candidate selected during a quiz.
+- **Elimination**: Records red/green screens and forced results with joker adjustments.
+- **User**: Administrative accounts for managing the system.
+
+## Architecture Notes
+
+### Routing
+- Routes are **attribute-based** (PHP 8 attributes in controller methods)
+- Configured in `config/routes/attributes.yaml` for automatic discovery
+- Main entry point: `config/routes.yaml`
+
+### Service Container & Dependency Injection
+- Services in `src/` are automatically registered via PSR-4 namespace `Tvdt\`
+- Exclusions: Entity, DependencyInjection, Kernel classes
+- Autowiring and autoconfiguration enabled by default
+- Service definitions in `config/services.yaml`
+
+### Database & Migrations
+- PostgreSQL-based with Doctrine ORM
+- Migrations in `migrations/` at project root, namespace `DoctrineMigrations` (intentionally not autoloaded); generate with `bin/console make:migration`
+- Test fixtures in `src/DataFixtures/` (loaded with `--group=test`)
+- Test database configured separately via `.env.test`
+
+### Testing Infrastructure
+- **PHPUnit 13** with DAMA Doctrine Test Bundle for transaction rollback
+- Bootstrap: `tests/bootstrap.php` loads env vars and autoloader; `tests/symfony-container.php` boots the test kernel/container (used by Rector)
+- Symfony test utilities (BrowserKit, CSS selectors) available
+- Coverage excluded from: `src/DataFixtures/`
+- Test environment: `APP_ENV=test` (set in phpunit.dist.xml)
+
+### Code Style & Standards
+- **PHP-CS-Fixer**: Symfony ruleset + risky rules enabled
+  - Strict types declaration required
+  - Trailing commas in multiline structures
+  - No else-only blocks
+- **Rector**: Aggressive modernization with all attribute sets + prepared sets (dead code, code quality, Doctrine, Symfony, PHPUnit)
+- **PHPStan**: Level 8 with extensions for Doctrine and Symfony
+- **Twig-CS-Fixer**: Template style enforcement
+- **Safe functions**: Use `thecodingmachine/safe` wrappers for standard PHP functions that return `false` on failure — they throw exceptions instead
+
+### Environment Configuration
+- `.env` - Local development defaults (uncommitted in .env.local)
+- `.env.dev` - Development overrides
+- `.env.test` - Test environment configuration
+- Production uses `composer dump-env prod` for compiled configuration
+- Key variables:
+  - `APP_ENV` - Environment (dev/test/prod)
+  - `DATABASE_URL` - PostgreSQL connection string
+  - `MAILER_SENDER` - From address for emails
+
+### Frontend Build
+- Asset mapper (no Node.js/Webpack) for JS/CSS bundling; JS modules declared in `importmap.php`
+- **Stimulus** controllers in `assets/controllers/`, **Turbo** for SPA-like navigation
+- Sass sources in `assets/styles/`, compiled via `bin/console sass:build`
+- Production: Assets precompiled during Docker build
+- Development: Watch mode enabled in FrankenPHP container
+
+## CI/CD Pipeline
+
+GitHub Actions workflow (`.github/workflows/ci.yml`):
+
+1. **Linting**: Dockerfile (hadolint), Twig templates
+2. **Code Quality**:
+   - PHP-CS-Fixer style check
+   - Twig-CS-Fixer style check
+   - PHPStan static analysis
+   - Rector dry-run
+3. **Integration Tests**:
+   - Docker image build and start services
+   - Database creation and migration
+   - Fixture loading
+   - Full PHPUnit test suite with JUnit XML output
+   - Doctrine schema validation
+4. **Build & Deploy** (on tags or main, disabled currently):
+   - Docker image push to GitHub Container Registry
+   - Sentry release creation
+   - Portainer webhook trigger for production deployment
+
+Runs on all pushes to main and pull requests. Concurrency cancels old runs on new commits.
+
+## Important Files & Conventions
+
+- **Kernel**: `src/Kernel.php` - Symfony kernel class
+- **AbstractController**: Base class for all controllers — defines route parameter regexes (`SEASON_CODE_REGEX`, `CANDIDATE_HASH_REGEX`) and flash helpers
+- **Flash Messages**: Use `FlashType` enum instead of string literals
+- **QuizSpreadsheetService**: Handles importing quizzes from XLSX files
+- **Rector container**: `tests/symfony-container.php` — boots a test kernel so Rector can resolve Symfony service types
+- **.gitignore**: Excludes var/, vendor/, .env.local, .phpunit.cache
+- **Dockerfile**: Multi-stage build with dev/prod separation, FrankenPHP-based
+- **Docker Compose**: PHP service with Caddy, PostgreSQL database, persistent volumes
+
+## Security & Authorization
+
+- Doctrine extensions enabled (timestamps, slugs, etc.)
+- Voter-based authorization in `src/Security/Voter/`
+- User entity with security encoding configured
+- CSRF protection enabled
+- Email verification available via SymfonyCasts bundle
+
+## Composer Scripts
+
+Auto-executed scripts on install/update:
+- `cache:clear` - Symfony cache clear
+- `assets:install` - Copy public assets
+- `importmap:install` - JS import map setup
+
+## Notes for Future Work
+
+- The backoffice elimination logic is in `Controller/Backoffice/PrepareEliminationController.php`
+- Quiz timing logic starts on candidate start click and stops on final answer selection
+- Background music feature noted but not yet implemented (requirements only)
+- Statistics functionality is marked TBD in README
