+# DevContainer Setup für Thats-Me
+
+## Was ist ein DevContainer?
+
+Ein DevContainer ist eine vollständige Entwicklungsumgebung in Docker. Cursor/VSCode läuft direkt im Container und Sie entwickeln mit allen Tools, die bereits vorinstalliert sind.
+
+## Voraussetzungen
+
+1. **Docker Desktop** muss laufen
+2. **Traefik Proxy** als externes Netzwerk:
+   ```bash
+   docker network create proxy
+   ```
+
+## DevContainer starten
+
+1. **In Cursor/VSCode:**
+
+   - Drücken Sie `Cmd+Shift+P` (macOS) oder `Ctrl+Shift+P` (Windows/Linux)
+   - Wählen Sie: **"Dev Containers: Reopen in Container"**
+   - Warten Sie, bis alle Container gebaut und gestartet sind
+
+2. **Beim ersten Start:**
+   - Der Laravel Container wird gebaut (kann einige Minuten dauern)
+   - Alle Services werden gestartet (MySQL, Redis, Mailpit, Quasar)
+   - Sie werden automatisch im Laravel Container eingeloggt
+
+## Was passiert beim Start?
+
+Der DevContainer startet folgende Services:
+
+- **laravel.test** - Laravel Backend (Sie arbeiten in diesem Container)
+- **mysql** - Datenbank
+- **redis** - Cache/Queue
+- **mailpit** - E-Mail Testing
+- **quasar.app** - Frontend App (läuft automatisch)
+
+## Arbeiten im Container
+
+### Terminal
+
+Das Terminal in Cursor/VSCode ist bereits im Container. Sie können direkt arbeiten:
+
+```bash
+# Sie sind im /var/www/html Verzeichnis (= ./backend vom Host)
+php artisan migrate
+php artisan serve
+composer install
+npm install
+npm run dev
+```
+
+### Verfügbare Services
+
+Im DevContainer können Sie direkt auf die anderen Services zugreifen:
+
+```bash
+# MySQL Verbindung
+mysql -h mysql -u sail -p
+# Passwort: password
+
+# Redis
+redis-cli -h redis
+
+# Composer
+composer install
+composer update
+
+# Artisan
+php artisan migrate
+php artisan tinker
+```
+
+## Zugriff von außerhalb
+
+### Von Ihrem Browser (Host)
+
+Die Ports werden automatisch weitergeleitet:
+
+- **Laravel App:** http://localhost (Port 80)
+- **Vite Dev Server:** http://localhost:5173
+- **Mailpit Dashboard:** http://localhost:8025
+- **Quasar App:** http://localhost:9000
+
+### Mit Traefik
+
+Wenn Traefik läuft, können Sie auch die Domains verwenden:
+
+- https://thats-me.test
+- https://portal.thats-me.test
+- https://api.thats-me.test
+- https://app.thats-me.test
+- https://assets.thats-me.test
+
+## Backend .env Konfiguration
+
+Stellen Sie sicher, dass `backend/.env` folgende Werte hat:
+
+```env
+DB_CONNECTION=mysql
+DB_HOST=mysql
+DB_PORT=3306
+DB_DATABASE=thats-me
+DB_USERNAME=sail
+DB_PASSWORD=password
+
+MAIL_MAILER=smtp
+MAIL_HOST=mailpit
+MAIL_PORT=1025
+
+REDIS_HOST=redis
+REDIS_PORT=6379
+```
+
+## Vite Dev Server starten
+
+```bash
+# Im DevContainer Terminal
+npm install
+npm run dev
+```
+
+Vite läuft dann auf Port 5173 und ist verfügbar unter:
+
+- http://localhost:5173 (vom Host)
+- https://assets.thats-me.test (mit Traefik)
+
+## Quasar App
+
+Die Quasar App läuft automatisch in einem separaten Container und ist verfügbar unter:
+
+- http://localhost:9000 (vom Host)
+- https://app.thats-me.test (mit Traefik)
+
+## Troubleshooting
+
+### Container startet nicht
+
+```bash
+# Schließen Sie den DevContainer
+# Öffnen Sie ein normales Terminal auf dem Host
+docker-compose down -v
+docker-compose build --no-cache
+# Dann neu starten: "Dev Containers: Reopen in Container"
+```
+
+### "Dockerfile not found" Fehler
+
+Stellen Sie sicher, dass Laravel Sail installiert ist:
+
+```bash
+cd backend
+composer require laravel/sail --dev
+```
+
+### Permission-Probleme
+
+Die User-IDs in `devcontainer.json` anpassen:
+
+```json
+"containerEnv": {
+    "WWWUSER": "1000",  // Ihre User-ID
+    "WWWGROUP": "1000"  // Ihre Group-ID
+}
+```
+
+Finden Sie Ihre IDs mit:
+
+```bash
+id -u  # User ID
+id -g  # Group ID
+```
+
+### Logs ansehen
+
+```bash
+# Im DevContainer Terminal
+docker-compose logs -f
+
+# Nur MySQL
+docker-compose logs -f mysql
+
+# Nur Quasar
+docker-compose logs -f quasar.app
+```
+
+## DevContainer verlassen
+
+1. Drücken Sie `Cmd+Shift+P` / `Ctrl+Shift+P`
+2. Wählen Sie: **"Dev Containers: Reopen Folder Locally"**
+
+## Container stoppen
+
+Nach dem Verlassen des DevContainers:
+
+```bash
+docker-compose down
+```
+
+## Vorteile des DevContainers
+
+✅ Alle arbeiten mit der gleichen Umgebung  
+✅ Keine lokale PHP/MySQL Installation nötig  
+✅ Automatische Service-Verwaltung  
+✅ Isolierte Entwicklungsumgebung  
+✅ Einfaches Onboarding für neue Entwickler
+

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+"That's Me" is a full-stack offline-first web application with a Quasar/Vue.js 3 frontend and a Laravel 12 backend, orchestrated via Docker Compose with Traefik reverse proxy.
+
+## Architecture
+
+The project is a monorepo with two independent applications:
+
+- **`frontend/`** — Quasar v2 SPA (Vue.js 3, Pinia, Vite). Serves the user-facing app at `app.thats-me.test`. Designed as offline-first with IndexedDB (via Dexie.js) for local storage and sync queue.
+- **`backend/`** — Laravel 12 (PHP 8.4). Serves multiple roles via separate domains:
+  - `thats-me.test` — Public landing page (Blade + Tailwind + Flux UI)
+  - `portal.thats-me.test` — Admin panel (Livewire/Volt + Tailwind + Flux UI)
+  - `api.thats-me.test` — REST API for the Quasar frontend (OAuth2 via Laravel Passport)
+  - `assets.thats-me.test` — Vite dev server (HMR)
+
+Data flow: User interaction → Vue component → Pinia store → IndexedDB → Sync queue → Laravel REST API → MySQL / Synology C2 Object Storage (for multimedia).
+
+## Development Environment (Docker)
+
+Requires Docker Desktop and a Traefik proxy network (`docker network create proxy`). Add domains to `/etc/hosts` pointing to `127.0.0.1`.
+
+```bash
+# Start all services
+docker-compose up -d
+
+# Access containers
+docker-compose exec laravel.test bash    # Laravel (PHP)
+docker-compose exec quasar.app sh        # Quasar (Node)
+docker-compose exec mysql mysql -u sail -p  # MySQL (password: password)
+```
+
+### Services & Ports
+
+| Service        | Port  | Purpose                    |
+|----------------|-------|----------------------------|
+| quasar.app     | 9000  | Quasar frontend dev server |
+| mysql           | 33070 | MySQL database             |
+| mailpit         | 8028  | Email testing dashboard    |
+| redis           | 6383  | Cache & queue              |
+| laravel.test   | 5180  | Vite dev server (HMR)     |
+
+## Common Commands
+
+### Backend (run inside `laravel.test` container or prefix with `docker-compose exec laravel.test`)
+
+```bash
+composer dev                                    # Full dev environment (server + queue + pail + npm dev)
+php artisan serve                               # Laravel server only
+php artisan test --compact                      # Run all tests (Pest v3)
+php artisan test --compact --filter=testName    # Run specific test
+vendor/bin/pint --dirty --format agent          # Format code (Laravel Pint)
+php artisan migrate                             # Run database migrations
+php artisan db:seed                             # Seed database
+npm run build                                   # Build backend assets with Vite
+```
+
+### Frontend (run inside `quasar.app` container or from `frontend/` directory)
+
+```bash
+npm run dev       # Quasar dev server with HMR
+npm run build     # Production build
+npm run lint      # ESLint check
+npm run format    # Prettier formatting
+```
+
+## Backend Conventions
+
+The `backend/CLAUDE.md` file contains comprehensive Laravel Boost guidelines that must be followed. Key points:
+
+- **PHP 8.4** with constructor property promotion, explicit return types, curly braces for all control structures
+- **Testing**: Every change must be tested with Pest v3. Run `php artisan test --compact` with filter for targeted runs. Create tests with `php artisan make:test --pest {name}`.
+- **Code formatting**: Always run `vendor/bin/pint --dirty --format agent` before finalizing changes.
+- **Artisan generators**: Use `php artisan make:*` commands with `--no-interaction` to create files (controllers, models, migrations, etc.)
+- **Database**: Prefer Eloquent over raw queries. Use `Model::query()` instead of `DB::`. Use eager loading to prevent N+1.
+- **Config**: Never use `env()` outside config files; use `config()` instead.
+- **Admin Panel UI**: Livewire + Volt (single-file components) styled with Tailwind CSS v4 + Flux UI (`<flux:*>` components)
+- **Laravel Boost MCP**: Use `search-docs`, `tinker`, `database-query`, `database-schema`, and `list-artisan-commands` tools when available.
+
+## Frontend Conventions
+
+- **State management**: Pinia stores in `frontend/src/stores/`
+- **Routing**: Vue Router with hash mode, config in `frontend/src/router/`
+- **UI framework**: Quasar components (preferred over custom HTML). Tailwind CSS only for specific customizations.
+- **Animation**: Anime.js for the "LifeWave" SVG visualization
+- **Build target**: ES2022, Firefox 115+, Chrome 115+, Safari 14+
+- **Dev server host**: `app.thats-me.test` on port 9000

+# Dev Notes – Stand 25.02.2026
+
+## node_modules-Konflikt: Mac ↔ Docker ↔ Cursor (gelöst)
+
+### Ausgangslage
+
+Die Quasar App läuft in drei Kontexten parallel:
+
+| Kontext | Pfad | Plattform |
+|---|---|---|
+| **`quasar.app` Docker-Service** | Docker Volume (isoliert) | Linux ARM64 |
+| **Cursor IDE Terminal** | `/workspace/frontend/node_modules` | Linux ARM64 |
+| **Mac Terminal** | `~/Sites/thats-me.local/frontend/node_modules` | macOS ARM64 |
+
+Der `frontend/`-Ordner ist überall **derselbe** (gemountetes Host-Filesystem). Rollup und andere native Pakete benötigen plattformspezifische Binaries – ein `npm install` auf einer Seite überschrieb bisher die Binaries der anderen.
+
+---
+
+### Fix 1 – Docker Volume für `quasar.app` (docker-compose.yml)
+
+Der `quasar.app`-Service nutzt ein eigenes benanntes Docker-Volume für `node_modules`. Dadurch bleibt sein Linux-`node_modules` vollständig vom Host isoliert:
+
+```yaml
+# quasar.app Service:
+volumes:
+    - './frontend:/app'
+    - 'quasar-node-modules:/app/node_modules'   # überschattet Host-Ordner
+
+# volumes-Block:
+volumes:
+    quasar-node-modules:
+        driver: local
+```
+
+Der `quasar.app`-Container führt beim Start automatisch `npm install && npm run dev` aus (in sein isoliertes Volume). Er ist damit **völlig unabhängig** vom Host-`node_modules`.
+
+---
+
+### Fix 2 – Rollup-Binaries als `optionalDependencies` (package.json)
+
+Das Cursor-Terminal und der Mac teilen denselben `node_modules`-Ordner. Um den gegenseitigen Konflikt abzumildern, wurden alle relevanten Rollup-Plattform-Binaries explizit als `optionalDependencies` eingetragen:
+
+```json
+"optionalDependencies": {
+    "@rollup/rollup-darwin-arm64": "^4.0.0",
+    "@rollup/rollup-linux-arm64-gnu": "^4.0.0",
+    "@rollup/rollup-linux-x64-gnu": "^4.0.0"
+}
+```
+
+npm installiert davon nur die zur aktuellen Plattform passenden, schlägt aber nie fehl wenn eine fehlt.
+
+---
+
+### Fix 3 – `npm run dev` repariert sich selbst (package.json)
+
+Das `dev`-Script führt vor dem Start automatisch `npm install` aus:
+
+```json
+"dev": "npm install && quasar dev"
+```
+
+Damit werden nach einem Mac-`npm install` die Linux-Binaries im Cursor-Terminal beim nächsten `npm run dev` automatisch nachgezogen.
+
+---
+
+### Wichtig: Cursor Terminal ≠ `quasar.app`-Container
+
+Das Cursor IDE Terminal hat **keinen** Zugriff auf das isolierte Docker-Volume des `quasar.app`-Services. Für den Web-Dev-Server gilt:
+
+- **Empfohlen:** `docker-compose up -d quasar.app` → App läuft unter `app.thats-me.test` (isoliertes Volume, kein Konflikt)
+- **Alternativ:** `npm run dev` direkt im Cursor-Terminal (teilt node_modules mit dem Mac, aber Fix 3 gleicht das aus)
+
+---
+
+### Workflow: iOS-Build auf dem Mac
+
+Nach einem `npm install` im Linux-Kontext (Cursor oder Docker) müssen auf dem Mac die node_modules neu installiert werden:
+
+```bash
+cd ~/Sites/thats-me.local/frontend
+rm -rf node_modules && npm install
+npx quasar build -m capacitor -T ios --ide
+```
+
+---
+
+## Allgemeiner Projekt-Stand
+
+- **Backend:** Laravel 12, API-Routes unter `api.thats-me.test`, OAuth2 via Passport
+- **Frontend:** Quasar v2 SPA, offline-first mit Dexie.js (IndexedDB)
+- **Mobile:** Capacitor für iOS/Android (in `frontend/src-capacitor/`)
+- **Neue Komponenten:**
+  - `AppSettingsModal.vue`, `ModalCard.vue`, `UserMenu.vue`, `ZoomControl.vue`
+  - `frontend/src/composables/`, `frontend/src/db/`, `frontend/src/services/`
+  - Backend API-Controller + Requests + Resources in `backend/app/Http/`
+  - Event-Model + Migrations + Factory
+
+---
+
+## Wichtige Domains (lokale Entwicklung)
+
+| Domain | Zweck |
+|---|---|
+| `app.thats-me.test` | Quasar Frontend (Quasar Dev-Server) |
+| `api.thats-me.test` | Laravel REST API |
+| `portal.thats-me.test` | Admin Panel |
+| `thats-me.test` | Landingpage |
+| `assets.thats-me.test` | Vite HMR (Laravel Backend Assets) |
+
+## Services & Ports
+
+| Service | Port | Purpose |
+|---|---|---|
+| `quasar.app` | 9000 | Quasar Frontend Dev-Server |
+| `mysql` | 33070 | MySQL Datenbank |
+| `mailpit` | 8028 | E-Mail Testing Dashboard |
+| `redis` | 6383 | Cache & Queue |

+
+### 3. Docker Container starten
+
+```bash
+docker-compose up -d
+```
+
+### 4. Laravel Installation abschließen
+
+Beim ersten Start:
+
+```bash
+# In den Laravel Container einsteigen
+docker-compose exec laravel.test bash
+
+# Composer Dependencies installieren
+composer install
+
+# Datenbank migrieren
+php artisan migrate
+
+# Optional: Seeder ausführen
+php artisan db:seed
+```
+
+### 5. Frontend Dependencies installieren
+
+Der Quasar Container installiert automatisch die Dependencies beim Start.
+Falls manuell nötig:
+
+```bash
+docker-compose exec quasar.app npm install
+```
+
+## Verwendung
+
+### Container starten
+
+```bash
+docker-compose up -d
+```
+
+### Container stoppen
+
+```bash
+docker-compose down
+```
+
+### Logs ansehen
+
+```bash
+# Alle Services
+docker-compose logs -f
+
+# Nur Laravel
+docker-compose logs -f laravel.test
+
+# Nur Quasar
+docker-compose logs -f quasar.app
+```
+
+### In Container einsteigen
+
+**Laravel:**
+
+```bash
+docker-compose exec laravel.test bash
+```
+
+**Quasar:**
+
+```bash
+docker-compose exec quasar.app sh
+```
+
+**MySQL:**
+
+```bash
+docker-compose exec mysql mysql -u sail -p
+# Passwort: password
+```
+
+### Artisan Commands
+
+```bash
+docker-compose exec laravel.test php artisan migrate
+docker-compose exec laravel.test php artisan cache:clear
+docker-compose exec laravel.test php artisan queue:work
+```
+
+### NPM Commands (Frontend)
+
+```bash
+docker-compose exec quasar.app npm run dev
+docker-compose exec quasar.app npm run build
+```
+
+## Zugriff auf die Anwendung
+
+### Mit Traefik (empfohlen)
+
+- **Hauptwebseite:** https://thats-me.test
+- **Admin Portal:** https://portal.thats-me.test
+- **API:** https://api.thats-me.test
+- **Frontend App:** https://app.thats-me.test
+- **Vite Assets:** https://assets.thats-me.test
+
+### Direkt über Ports
+
+- **Laravel App:** http://localhost (Port 80 über Traefik)
+- **Vite Dev Server:** http://localhost:5179 (Host) → 5173 (Container)
+- **Quasar App:** http://localhost:9000
+- **Mailpit Dashboard:** http://localhost:8028
+- **MySQL:** localhost:33070
+- **Redis:** localhost:6383
+
+## Vite Development Server
+
+Um den Vite Dev Server für Laravel zu starten:
+
+```bash
+docker-compose exec laravel.test npm install
+docker-compose exec laravel.test npm run dev
+```
+
+Dann ist HMR (Hot Module Replacement) unter https://assets.thats-me.test verfügbar.
+
+## Troubleshooting
+
+### Proxy-Netzwerk existiert nicht
+
+```bash
+docker network create proxy
+```
+
+### Port-Konflikte
+
+Ändere die Ports in der `.env` Datei:
+
+```env
+FORWARD_DB_PORT=33071
+FORWARD_MAILPIT_DASHBOARD_PORT=8029
+QUASAR_PORT=9001
+VITE_PORT=5180
+```
+
+### Permission-Probleme
+
+```bash
+# User/Group IDs in .env anpassen
+WWWUSER=1000
+WWWGROUP=1000
+```
+
+### Container neu bauen
+
+```bash
+docker-compose down -v
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+### Quasar startet nicht
+
+```bash
+# Manuell im Container starten
+docker-compose exec quasar.app sh
+cd /app
+npm install
+npm run dev
+```
+
+## Entwicklung ohne Traefik
+
+Falls Sie kein Traefik haben, können Sie die Container auch direkt über Ports erreichen:
+
+1. Entfernen Sie die `labels` Sektion aus `docker-compose.yml`
+2. Aktivieren Sie den Port-Mapping für Laravel:
+   ```yaml
+   ports:
+     - "${APP_PORT:-80}:80"
+     - "${VITE_PORT:-5173}:5173"
+   ```
+3. Zugriff dann über:
+   - Laravel: http://localhost
+   - Vite: http://localhost:5173
+   - Quasar: http://localhost:9000
+
+## Nützliche Befehle
+
+```bash
+# Container Status
+docker-compose ps
+
+# Container neu starten
+docker-compose restart
+
+# Bestimmten Service neu starten
+docker-compose restart laravel.test
+
+# Container und Volumes löschen
+docker-compose down -v
+
+# Logs von heute
+docker-compose logs --since 24h
+
+# Ressourcen-Nutzung
+docker stats
+```

+# Laravel Boost Guidelines
+
+The Laravel Boost guidelines are specifically curated by Laravel maintainers for this application. These guidelines should be followed closely to ensure the best experience when building Laravel applications.
+
+## Foundational Context
+
+This application is a Laravel application and its main Laravel ecosystems package & versions are below. You are an expert with them all. Ensure you abide by these specific packages & versions.
+
+- php - 8.4.13
+- laravel/framework (LARAVEL) - v12
+- laravel/prompts (PROMPTS) - v0
+- livewire/flux (FLUXUI_FREE) - v2
+- livewire/livewire (LIVEWIRE) - v4
+- livewire/volt (VOLT) - v1
+- laravel/boost (BOOST) - v2
+- laravel/mcp (MCP) - v0
+- laravel/pail (PAIL) - v1
+- laravel/pint (PINT) - v1
+- laravel/sail (SAIL) - v1
+- pestphp/pest (PEST) - v3
+- phpunit/phpunit (PHPUNIT) - v11
+- tailwindcss (TAILWINDCSS) - v4
+
+## Skills Activation
+
+This project has domain-specific skills available. You MUST activate the relevant skill whenever you work in that domain—don't wait until you're stuck.
+
+- `fluxui-development` — Develops UIs with Flux UI Free components. Activates when creating buttons, forms, modals, inputs, dropdowns, checkboxes, or UI components; replacing HTML form elements with Flux; working with flux: components; or when the user mentions Flux, component library, UI components, form fields, or asks about available Flux components.
+- `volt-development` — Develops single-file Livewire components with Volt. Activates when creating Volt components, converting Livewire to Volt, working with @volt directive, functional or class-based Volt APIs; or when the user mentions Volt, single-file components, functional Livewire, or inline component logic in Blade files.
+- `pest-testing` — Tests applications using the Pest 3 PHP framework. Activates when writing tests, creating unit or feature tests, adding assertions, testing Livewire components, architecture testing, debugging test failures, working with datasets or mocking; or when the user mentions test, spec, TDD, expects, assertion, coverage, or needs to verify functionality works.
+- `tailwindcss-development` — Styles applications using Tailwind CSS v4 utilities. Activates when adding styles, restyling components, working with gradients, spacing, layout, flex, grid, responsive design, dark mode, colors, typography, or borders; or when the user mentions CSS, styling, classes, Tailwind, restyle, hero section, cards, buttons, or any visual/UI changes.
+
+## Conventions
+
+- You must follow all existing code conventions used in this application. When creating or editing a file, check sibling files for the correct structure, approach, and naming.
+- Use descriptive names for variables and methods. For example, `isRegisteredForDiscounts`, not `discount()`.
+- Check for existing components to reuse before writing a new one.
+
+## Verification Scripts
+
+- Do not create verification scripts or tinker when tests cover that functionality and prove they work. Unit and feature tests are more important.
+
+## Application Structure & Architecture
+
+- Stick to existing directory structure; don't create new base folders without approval.
+- Do not change the application's dependencies without approval.
+
+## Frontend Bundling
+
+- If the user doesn't see a frontend change reflected in the UI, it could mean they need to run `npm run build`, `npm run dev`, or `composer run dev`. Ask them.
+
+## Documentation Files
+
+- You must only create documentation files if explicitly requested by the user.
+
+## Replies
+
+- Be concise in your explanations - focus on what's important rather than explaining obvious details.
+
+=== boost rules ===
+
+# Laravel Boost
+
+- Laravel Boost is an MCP server that comes with powerful tools designed specifically for this application. Use them.
+
+## Artisan
+
+- Use the `list-artisan-commands` tool when you need to call an Artisan command to double-check the available parameters.
+
+## URLs
+
+- Whenever you share a project URL with the user, you should use the `get-absolute-url` tool to ensure you're using the correct scheme, domain/IP, and port.
+
+## Tinker / Debugging
+
+- You should use the `tinker` tool when you need to execute PHP to debug code or query Eloquent models directly.
+- Use the `database-query` tool when you only need to read from the database.
+- Use the `database-schema` tool to inspect table structure before writing migrations or models.
+
+## Reading Browser Logs With the `browser-logs` Tool
+
+- You can read browser logs, errors, and exceptions using the `browser-logs` tool from Boost.
+- Only recent browser logs will be useful - ignore old logs.
+
+## Searching Documentation (Critically Important)
+
+- Boost comes with a powerful `search-docs` tool you should use before trying other approaches when working with Laravel or Laravel ecosystem packages. This tool automatically passes a list of installed packages and their versions to the remote Boost API, so it returns only version-specific documentation for the user's circumstance. You should pass an array of packages to filter on if you know you need docs for particular packages.
+- Search the documentation before making code changes to ensure we are taking the correct approach.
+- Use multiple, broad, simple, topic-based queries at once. For example: `['rate limiting', 'routing rate limiting', 'routing']`. The most relevant results will be returned first.
+- Do not add package names to queries; package information is already shared. For example, use `test resource table`, not `filament 4 test resource table`.
+
+### Available Search Syntax
+
+1. Simple Word Searches with auto-stemming - query=authentication - finds 'authenticate' and 'auth'.
+2. Multiple Words (AND Logic) - query=rate limit - finds knowledge containing both "rate" AND "limit".
+3. Quoted Phrases (Exact Position) - query="infinite scroll" - words must be adjacent and in that order.
+4. Mixed Queries - query=middleware "rate limit" - "middleware" AND exact phrase "rate limit".
+5. Multiple Queries - queries=["authentication", "middleware"] - ANY of these terms.
+
+=== php rules ===
+
+# PHP
+
+- Always use curly braces for control structures, even for single-line bodies.
+
+## Constructors
+
+- Use PHP 8 constructor property promotion in `__construct()`.
+    - `public function __construct(public GitHub $github) { }`
+- Do not allow empty `__construct()` methods with zero parameters unless the constructor is private.
+
+## Type Declarations
+
+- Always use explicit return type declarations for methods and functions.
+- Use appropriate PHP type hints for method parameters.
+
+<!-- Explicit Return Types and Method Params -->
+```php
+protected function isAccessible(User $user, ?string $path = null): bool
+{
+    ...
+}
+```
+
+## Enums
+
+- Typically, keys in an Enum should be TitleCase. For example: `FavoritePerson`, `BestLake`, `Monthly`.
+
+## Comments
+
+- Prefer PHPDoc blocks over inline comments. Never use comments within the code itself unless the logic is exceptionally complex.
+
+## PHPDoc Blocks
+
+- Add useful array shape type definitions when appropriate.
+
+=== tests rules ===
+
+# Test Enforcement
+
+- Every change must be programmatically tested. Write a new test or update an existing test, then run the affected tests to make sure they pass.
+- Run the minimum number of tests needed to ensure code quality and speed. Use `php artisan test --compact` with a specific filename or filter.
+
+=== laravel/core rules ===
+
+# Do Things the Laravel Way
+
+- Use `php artisan make:` commands to create new files (i.e. migrations, controllers, models, etc.). You can list available Artisan commands using the `list-artisan-commands` tool.
+- If you're creating a generic PHP class, use `php artisan make:class`.
+- Pass `--no-interaction` to all Artisan commands to ensure they work without user input. You should also pass the correct `--options` to ensure correct behavior.
+
+## Database
+
+- Always use proper Eloquent relationship methods with return type hints. Prefer relationship methods over raw queries or manual joins.
+- Use Eloquent models and relationships before suggesting raw database queries.
+- Avoid `DB::`; prefer `Model::query()`. Generate code that leverages Laravel's ORM capabilities rather than bypassing them.
+- Generate code that prevents N+1 query problems by using eager loading.
+- Use Laravel's query builder for very complex database operations.
+
+### Model Creation
+
+- When creating new models, create useful factories and seeders for them too. Ask the user if they need any other things, using `list-artisan-commands` to check the available options to `php artisan make:model`.
+
+### APIs & Eloquent Resources
+
+- For APIs, default to using Eloquent API Resources and API versioning unless existing API routes do not, then you should follow existing application convention.
+
+## Controllers & Validation
+
+- Always create Form Request classes for validation rather than inline validation in controllers. Include both validation rules and custom error messages.
+- Check sibling Form Requests to see if the application uses array or string based validation rules.
+
+## Authentication & Authorization
+
+- Use Laravel's built-in authentication and authorization features (gates, policies, Sanctum, etc.).
+
+## URL Generation
+
+- When generating links to other pages, prefer named routes and the `route()` function.
+
+## Queues
+
+- Use queued jobs for time-consuming operations with the `ShouldQueue` interface.
+
+## Configuration
+
+- Use environment variables only in configuration files - never use the `env()` function directly outside of config files. Always use `config('app.name')`, not `env('APP_NAME')`.
+
+## Testing
+
+- When creating models for tests, use the factories for the models. Check if the factory has custom states that can be used before manually setting up the model.
+- Faker: Use methods such as `$this->faker->word()` or `fake()->randomDigit()`. Follow existing conventions whether to use `$this->faker` or `fake()`.
+- When creating tests, make use of `php artisan make:test [options] {name}` to create a feature test, and pass `--unit` to create a unit test. Most tests should be feature tests.
+
+## Vite Error
+
+- If you receive an "Illuminate\Foundation\ViteException: Unable to locate file in Vite manifest" error, you can run `npm run build` or ask the user to run `npm run dev` or `composer run dev`.
+
+=== laravel/v12 rules ===
+
+# Laravel 12
+
+- CRITICAL: ALWAYS use `search-docs` tool for version-specific Laravel documentation and updated code examples.
+- Since Laravel 11, Laravel has a new streamlined file structure which this project uses.
+
+## Laravel 12 Structure
+
+- In Laravel 12, middleware are no longer registered in `app/Http/Kernel.php`.
+- Middleware are configured declaratively in `bootstrap/app.php` using `Application::configure()->withMiddleware()`.
+- `bootstrap/app.php` is the file to register middleware, exceptions, and routing files.
+- `bootstrap/providers.php` contains application specific service providers.
+- The `app\Console\Kernel.php` file no longer exists; use `bootstrap/app.php` or `routes/console.php` for console configuration.
+- Console commands in `app/Console/Commands/` are automatically available and do not require manual registration.
+
+## Database
+
+- When modifying a column, the migration must include all of the attributes that were previously defined on the column. Otherwise, they will be dropped and lost.
+- Laravel 12 allows limiting eagerly loaded records natively, without external packages: `$query->latest()->limit(10);`.
+
+### Models
+
+- Casts can and likely should be set in a `casts()` method on a model rather than the `$casts` property. Follow existing conventions from other models.
+
+=== fluxui-free/core rules ===
+
+# Flux UI Free
+
+- Flux UI is the official Livewire component library. This project uses the free edition, which includes all free components and variants but not Pro components.
+- Use `<flux:*>` components when available; they are the recommended way to build Livewire interfaces.
+- IMPORTANT: Activate `fluxui-development` when working with Flux UI components.
+
+=== volt/core rules ===
+
+# Livewire Volt
+
+- Single-file Livewire components: PHP logic and Blade templates in one file.
+- Always check existing Volt components to determine functional vs class-based style.
+- IMPORTANT: Always use `search-docs` tool for version-specific Volt documentation and updated code examples.
+- IMPORTANT: Activate `volt-development` every time you're working with a Volt or single-file component-related task.
+
+=== pint/core rules ===
+
+# Laravel Pint Code Formatter
+
+- You must run `vendor/bin/pint --dirty --format agent` before finalizing changes to ensure your code matches the project's expected style.
+- Do not run `vendor/bin/pint --test --format agent`, simply run `vendor/bin/pint --format agent` to fix any formatting issues.
+
+=== pest/core rules ===
+
+## Pest
+
+- This project uses Pest for testing. Create tests: `php artisan make:test --pest {name}`.
+- Run tests: `php artisan test --compact` or filter: `php artisan test --compact --filter=testName`.
+- Do NOT delete tests without approval.
+- CRITICAL: ALWAYS use `search-docs` tool for version-specific Pest documentation and updated code examples.
+- IMPORTANT: Activate `pest-testing` every time you're working with a Pest or testing-related task.
+
+=== tailwindcss/core rules ===
+
+# Tailwind CSS
+
+- Always use existing Tailwind conventions; check project patterns before adding new ones.
+- IMPORTANT: Always use `search-docs` tool for version-specific Tailwind CSS documentation and updated code examples. Never rely on training data.
+- IMPORTANT: Activate `tailwindcss-development` every time you're working with a Tailwind CSS or styling-related task.

+- Use Eloquent models and relationships before suggesting raw database queries.
+- Avoid `DB::`; prefer `Model::query()`. Generate code that leverages Laravel's ORM capabilities rather than bypassing them.
+- Generate code that prevents N+1 query problems by using eager loading.
+- Use Laravel's query builder for very complex database operations.
+
+### Model Creation
+
+- When creating new models, create useful factories and seeders for them too. Ask the user if they need any other things, using `list-artisan-commands` to check the available options to `php artisan make:model`.
+
+### APIs & Eloquent Resources
+
+- For APIs, default to using Eloquent API Resources and API versioning unless existing API routes do not, then you should follow existing application convention.
+
+## Controllers & Validation
+
+- Always create Form Request classes for validation rather than inline validation in controllers. Include both validation rules and custom error messages.
+- Check sibling Form Requests to see if the application uses array or string based validation rules.
+
+## Authentication & Authorization
+
+- Use Laravel's built-in authentication and authorization features (gates, policies, Sanctum, etc.).
+
+## URL Generation
+
+- When generating links to other pages, prefer named routes and the `route()` function.
+
+## Queues
+
+- Use queued jobs for time-consuming operations with the `ShouldQueue` interface.
+
+## Configuration
+
+- Use environment variables only in configuration files - never use the `env()` function directly outside of config files. Always use `config('app.name')`, not `env('APP_NAME')`.
+
+## Testing
+
+- When creating models for tests, use the factories for the models. Check if the factory has custom states that can be used before manually setting up the model.
+- Faker: Use methods such as `$this->faker->word()` or `fake()->randomDigit()`. Follow existing conventions whether to use `$this->faker` or `fake()`.
+- When creating tests, make use of `php artisan make:test [options] {name}` to create a feature test, and pass `--unit` to create a unit test. Most tests should be feature tests.
+
+## Vite Error
+
+- If you receive an "Illuminate\Foundation\ViteException: Unable to locate file in Vite manifest" error, you can run `npm run build` or ask the user to run `npm run dev` or `composer run dev`.
+
+=== laravel/v12 rules ===
+
+# Laravel 12
+
+- CRITICAL: ALWAYS use `search-docs` tool for version-specific Laravel documentation and updated code examples.
+- Since Laravel 11, Laravel has a new streamlined file structure which this project uses.
+
+## Laravel 12 Structure
+
+- In Laravel 12, middleware are no longer registered in `app/Http/Kernel.php`.
+- Middleware are configured declaratively in `bootstrap/app.php` using `Application::configure()->withMiddleware()`.
+- `bootstrap/app.php` is the file to register middleware, exceptions, and routing files.
+- `bootstrap/providers.php` contains application specific service providers.
+- The `app\Console\Kernel.php` file no longer exists; use `bootstrap/app.php` or `routes/console.php` for console configuration.
+- Console commands in `app/Console/Commands/` are automatically available and do not require manual registration.
+
+## Database
+
+- When modifying a column, the migration must include all of the attributes that were previously defined on the column. Otherwise, they will be dropped and lost.
+- Laravel 12 allows limiting eagerly loaded records natively, without external packages: `$query->latest()->limit(10);`.
+
+### Models
+
+- Casts can and likely should be set in a `casts()` method on a model rather than the `$casts` property. Follow existing conventions from other models.
+
+=== fluxui-free/core rules ===
+
+# Flux UI Free
+
+- Flux UI is the official Livewire component library. This project uses the free edition, which includes all free components and variants but not Pro components.
+- Use `<flux:*>` components when available; they are the recommended way to build Livewire interfaces.
+- IMPORTANT: Activate `fluxui-development` when working with Flux UI components.
+
+=== volt/core rules ===
+
+# Livewire Volt
+
+- Single-file Livewire components: PHP logic and Blade templates in one file.
+- Always check existing Volt components to determine functional vs class-based style.
+- IMPORTANT: Always use `search-docs` tool for version-specific Volt documentation and updated code examples.
+- IMPORTANT: Activate `volt-development` every time you're working with a Volt or single-file component-related task.
+
+=== pint/core rules ===
+
+# Laravel Pint Code Formatter
+
+- You must run `vendor/bin/pint --dirty --format agent` before finalizing changes to ensure your code matches the project's expected style.
+- Do not run `vendor/bin/pint --test --format agent`, simply run `vendor/bin/pint --format agent` to fix any formatting issues.
+
+=== pest/core rules ===
+
+## Pest
+
+- This project uses Pest for testing. Create tests: `php artisan make:test --pest {name}`.
+- Run tests: `php artisan test --compact` or filter: `php artisan test --compact --filter=testName`.
+- Do NOT delete tests without approval.
+- CRITICAL: ALWAYS use `search-docs` tool for version-specific Pest documentation and updated code examples.
+- IMPORTANT: Activate `pest-testing` every time you're working with a Pest or testing-related task.
+
+=== tailwindcss/core rules ===
+
+# Tailwind CSS
+
+- Always use existing Tailwind conventions; check project patterns before adding new ones.
+- IMPORTANT: Always use `search-docs` tool for version-specific Tailwind CSS documentation and updated code examples. Never rely on training data.
+- IMPORTANT: Activate `tailwindcss-development` every time you're working with a Tailwind CSS or styling-related task.
