+# Git-Based Deployment mit Gitea
+
+## Übersicht
+
+Das Git-basierte Deployment Playbook (`deploy-git-based.yml`) ermöglicht Zero-Downtime Deployments mit Gitea als Git-Repository-Server.
+
+## Voraussetzungen
+
+### 1. Gitea Server Setup
+
+Der Gitea Server muss für den Production-Server erreichbar sein. Es gibt zwei Optionen:
+
+#### Option A: Öffentlich erreichbarer Gitea Server (Empfohlen für Production)
+
+```bash
+# Gitea muss über das Internet erreichbar sein
+git_repo: "git@git.michaelschiemer.de:michael/michaelschiemer.git"
+```
+
+**Erforderlich**:
+- Öffentliche IP oder Domain für Gitea
+- Firewall-Regel für Port 2222 (SSH)
+- SSL/TLS für Webinterface (Port 9443/3000)
+
+#### Option B: Gitea auf dem Production-Server
+
+```bash
+# Gitea läuft auf demselben Server wie die Anwendung
+git_repo: "git@localhost:michael/michaelschiemer.git"
+```
+
+**Erforderlich**:
+- Gitea Container auf Production-Server deployen
+- Docker Compose Setup auf Production-Server
+- Lokale SSH-Konfiguration
+
+### 2. SSH Key Setup
+
+Der Deploy-User auf dem Production-Server benötigt einen SSH-Key:
+
+```bash
+# Auf dem Production-Server
+ssh-keygen -t ed25519 -C "deployment@michaelschiemer" -f ~/.ssh/gitea_deploy_key -N ""
+
+# Public Key zu Gitea hinzufügen (via Web-UI oder API)
+cat ~/.ssh/gitea_deploy_key.pub
+```
+
+### 3. SSH Keys im Secrets-Verzeichnis
+
+Die SSH Keys müssen im `deployment/infrastructure/secrets/` Verzeichnis liegen:
+
+```bash
+deployment/infrastructure/secrets/
+├── .gitignore          # Schützt Keys vor versehentlichem Commit
+├── gitea_deploy_key    # Private Key
+└── gitea_deploy_key.pub  # Public Key
+```
+
+**WICHTIG**: Das `secrets/` Verzeichnis ist via `.gitignore` geschützt und darf NIEMALS committed werden!
+
+## Deployment-Ablauf
+
+### 1. SSH Key auf Production-Server kopieren
+
+Das Playbook kopiert automatisch die SSH Keys aus `secrets/` auf den Production-Server:
+
+```yaml
+- name: Copy Gitea deploy SSH private key
+  copy:
+    src: "{{ playbook_dir }}/../secrets/gitea_deploy_key"
+    dest: "/home/{{ app_user }}/.ssh/gitea_deploy_key"
+    mode: '0600'
+```
+
+### 2. SSH-Konfiguration
+
+Das Playbook erstellt automatisch die SSH-Konfiguration:
+
+```ssh
+Host localhost
+    HostName localhost
+    Port 2222
+    User git
+    IdentityFile ~/.ssh/gitea_deploy_key
+    StrictHostKeyChecking no
+    UserKnownHostsFile /dev/null
+
+Host git.michaelschiemer.de
+    HostName git.michaelschiemer.de
+    Port 2222
+    User git
+    IdentityFile ~/.ssh/gitea_deploy_key
+    StrictHostKeyChecking no
+    UserKnownHostsFile /dev/null
+```
+
+### 3. Git Clone
+
+Das Playbook clont das Repository in ein Release-Verzeichnis:
+
+```bash
+/var/www/michaelschiemer/
+├── releases/
+│   ├── 1761524417/     # Timestamp-basierte Releases
+│   └── v1.0.0/         # Tag-basierte Releases
+├── shared/             # Shared Directories (symlinked)
+│   ├── storage/
+│   └── .env.production
+└── current -> releases/1761524417  # Symlink auf aktives Release
+```
+
+### 4. Zero-Downtime Deployment
+
+- Neues Release wird geclont
+- Dependencies installiert
+- Symlinks erstellt
+- `current` Symlink atomar gewechselt
+- Health Check durchgeführt
+- Bei Fehler: Automatischer Rollback
+
+## Deployment ausführen
+
+### Standard Deployment (main Branch)
+
+```bash
+cd deployment/infrastructure
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-git-based.yml
+```
+
+### Tag-basiertes Deployment
+
+```bash
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-git-based.yml \
+  --extra-vars "release_tag=v1.0.0"
+```
+
+### Custom Branch Deployment
+
+```bash
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-git-based.yml \
+  --extra-vars "git_branch=develop"
+```
+
+## Konfiguration anpassen
+
+### Git Repository URL ändern
+
+In `deploy-git-based.yml`:
+
+```yaml
+vars:
+  git_repo: "git@git.michaelschiemer.de:michael/michaelschiemer.git"
+  # Oder für lokales Testing:
+  # git_repo: "git@localhost:michael/michaelschiemer.git"
+```
+
+### Shared Directories anpassen
+
+```yaml
+vars:
+  shared_dirs:
+    - storage/logs
+    - storage/cache
+    - storage/sessions
+    - storage/uploads
+    - public/uploads
+
+  shared_files:
+    - .env.production
+```
+
+## Troubleshooting
+
+### Fehler: "Connection refused" zu Gitea
+
+**Problem**: Der Production-Server kann Gitea nicht erreichen.
+
+**Lösung**:
+1. Prüfe, ob Gitea öffentlich erreichbar ist: `nc -zv git.michaelschiemer.de 2222`
+2. Prüfe Firewall-Regeln auf dem Gitea-Server
+3. Für lokales Testing: Verwende rsync-based Deployment stattdessen
+
+### Fehler: "Permission denied (publickey)"
+
+**Problem**: SSH Key ist nicht korrekt konfiguriert.
+
+**Lösung**:
+1. Prüfe, ob der Public Key in Gitea hinzugefügt wurde
+2. Prüfe SSH Key Permissions: `chmod 600 ~/.ssh/gitea_deploy_key`
+3. Teste SSH-Verbindung manuell: `ssh -p 2222 -i ~/.ssh/gitea_deploy_key git@git.michaelschiemer.de`
+
+### Health Check schlägt fehl
+
+**Problem**: Deployment-Health-Check failed.
+
+**Lösung**:
+1. Automatischer Rollback wurde durchgeführt
+2. Prüfe Logs: `tail -f /var/www/michaelschiemer/deploy.log`
+3. Prüfe Application Logs: `/var/www/michaelschiemer/shared/storage/logs/`
+
+## Comparison: Git-based vs rsync-based
+
+### Git-based Deployment (Dieser Playbook)
+
+**Vorteile**:
+- Zero-Downtime durch Symlink-Switch
+- Atomare Releases mit Rollback-Fähigkeit
+- Git-Historie auf Production-Server
+- Einfache Rollbacks zu vorherigen Releases
+
+**Nachteile**:
+- Gitea Server muss erreichbar sein
+- Zusätzliche Infrastruktur (Gitea)
+- SSH Key Management erforderlich
+
+### rsync-based Deployment
+
+**Vorteile**:
+- Keine zusätzliche Infrastruktur
+- Funktioniert mit lokalem Development-Environment
+- Schneller für kleine Änderungen
+
+**Nachteile**:
+- Kein Zero-Downtime ohne zusätzliche Logik
+- Keine Git-Historie auf Server
+- Rollback komplizierter
+
+## Empfehlung
+
+**Für Production**: Git-based Deployment mit öffentlich erreichbarem Gitea Server
+**Für Development/Testing**: rsync-based Deployment (bereits implementiert und getestet)

+## Deployment-Architektur
+
+### Release Structure

+```
+
+### Zero-Downtime Process
+
+```
+1. Build Assets (local)
+   ↓
+2. Rsync to new release directory
+   ↓
+3. Create symlinks zu shared directories
+   ↓
+4. Start Docker containers
+   ↓
+5. Health Check (3 retries)
+   ├─ Success → Switch 'current' symlink (atomic)
+   └─ Failure → Rollback zu previous release
+   ↓
+6. Cleanup old releases (keep last 5)
+```
+
+## Voraussetzungen
+
+### 1. SSH Key Setup
+
+SSH Keys für Production Server müssen konfiguriert sein:
+
+```bash
+# SSH config in ~/.ssh/config
+Host michaelschiemer-prod
+    HostName 94.16.110.151
+    User deploy
+    IdentityFile ~/.ssh/production
+    StrictHostKeyChecking no
+```
+
+### 2. Production Server Requirements
+
+- **User**: `deploy` user mit sudo Rechten
+- **Docker**: Docker und Docker Compose installiert
+- **Directory**: `/home/deploy/michaelschiemer` mit korrekten Permissions
+
+### 3. Local Development Setup
+
+- **Composer**: Für `composer install`
+- **NPM**: Für `npm run build`
+- **Git**: Für Tag-basiertes Release Management (optional)
+- **Ansible**: Ansible ≥2.13 installiert
+
+## Deployment-Workflows
+
+### Standard Deployment (Timestamp-based)
+
+Deployiert aktuellen Stand ohne Git Tag:
+
+```bash
+cd deployment/infrastructure
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml
+```
+
+**Release Name**: Unix Timestamp (z.B. `1761499893`)
+
+### Tagged Release Deployment (Recommended)
+
+Deployiert spezifischen Git Tag:
+
+```bash
+# Option 1: Tag explizit angeben
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml \
+  --extra-vars "release_tag=v1.2.3"
+
+# Option 2: Aktuellen Git Tag verwenden (auto-detected)
+git tag v1.2.3
+git push origin v1.2.3
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml
+```
+
+**Release Name**: Git Tag (z.B. `v1.2.3`)
+
+### Force Deployment (Override Lock)
+
+Wenn ein Deployment Lock existiert:
+
+```bash
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml \
+  --extra-vars "force_deploy=true"
+```
+
+## Release Management
+
+### Git Tag Workflow
+
+**Semantic Versioning** wird empfohlen:
+
+```bash
+# 1. Create Git tag
+git tag -a v1.2.3 -m "Release v1.2.3: Feature XYZ"
+git push origin v1.2.3
+
+# 2. Deploy tagged release
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml \
+  --extra-vars "release_tag=v1.2.3"
+
+# 3. Verify deployment
+ssh deploy@94.16.110.151 'ls -la /home/deploy/michaelschiemer/releases/'
+```
+
+### Auto-Detection von Git Tags
+
+Wenn `release_tag` nicht angegeben wird, versucht das Playbook automatisch den aktuellen Git Tag zu verwenden:
+
+```bash
+# Auf einem getaggten Commit
+git describe --tags --exact-match  # Zeigt: v1.2.3
+
+# Deployment verwendet automatisch v1.2.3 als Release Name
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml
+```
+
+**Fallback**: Wenn kein Git Tag vorhanden → Timestamp als Release Name
+
+### Release List anzeigen
+
+```bash
+ansible -i inventories/production/hosts.yml web_servers -b -a \
+  "ls -lt /home/deploy/michaelschiemer/releases | head -10"
+```
+
+**Output**:
+```
+total 20
+drwxr-xr-x 10 deploy deploy 4096 Oct 26 18:50 v1.2.3
+drwxr-xr-x 10 deploy deploy 4096 Oct 25 14:32 v1.2.2
+drwxr-xr-x 10 deploy deploy 4096 Oct 24 10:15 1761499893
+drwxr-xr-x 10 deploy deploy 4096 Oct 23 09:00 v1.2.1
+lrwxrwxrwx  1 deploy deploy   56 Oct 26 18:50 current -> /home/deploy/michaelschiemer/releases/v1.2.3
+```
+
+## Rollback Mechanisms
+
+### Automatic Rollback
+
+Bei Health Check Failure rollback das Playbook automatisch:
+
+1. **Stop failed release containers**
+2. **Switch `current` symlink** zurück zu `previous_release`
+3. **Start previous release containers**
+4. **Remove failed release directory**
+5. **Log rollback event**
+
+**Trigger**: Health Check Status ≠ 200 (nach 3 Retries mit 5s delay)
+
+### Manual Rollback
+
+Manueller Rollback zu vorherigem Release:
+
+```bash
+# 1. List available releases
+ansible -i inventories/production/hosts.yml web_servers -b -a \
+  "ls -lt /home/deploy/michaelschiemer/releases"
+
+# 2. Identify target release (z.B. v1.2.2)
+TARGET_RELEASE="v1.2.2"
+
+# 3. Manual rollback via Ansible
+ansible -i inventories/production/hosts.yml web_servers -b -m shell -a "
+  cd /home/deploy/michaelschiemer && \
+  docker compose -f current/docker-compose.yml -f current/docker-compose.production.yml down && \
+  ln -sfn releases/${TARGET_RELEASE} current && \
+  docker compose -f current/docker-compose.yml -f current/docker-compose.production.yml up -d
+"
+
+# 4. Verify rollback
+curl -k https://94.16.110.151/health/summary
+```
+
+**Oder**: Erstelle Rollback Playbook:
+
+```yaml
+# playbooks/rollback-rsync.yml

+## Health Checks
+
+### Configured Health Endpoints
+
+**Primary Health Check**: `https://{{ ansible_host }}/health/summary`
+
+**Retry Strategy**:
+- Retries: 3
+- Delay: 5 seconds
+- Success: HTTP 200 status code
+
+### Health Check Flow
+

+## Monitoring & Logging
+
+### Deployment Log
+
+Alle Deployments werden geloggt:
+
+```bash
+# Deployment log anzeigen
+ssh deploy@94.16.110.151 'tail -50 /home/deploy/michaelschiemer/deploy.log'
+```
+
+**Log Format**:
+```
+[2024-10-26T18:50:30Z] Deployment started - Release: v1.2.3 - User: michael
+[2024-10-26T18:50:35Z] Release: v1.2.3 | Git Hash: a1b2c3d | Commit: a1b2c3d4e5f6g7h8i9j0
+[2024-10-26T18:50:50Z] Symlink switched: /home/deploy/michaelschiemer/current -> releases/v1.2.3
+[2024-10-26T18:50:55Z] Health check: 200
+[2024-10-26T18:50:56Z] Cleanup: Kept 5 releases, removed 1
+[2024-10-26T18:50:57Z] Deployment completed successfully - Release: v1.2.3
+```
+
+### Docker Logs
+
+```bash
+# Application logs
+ssh deploy@94.16.110.151 'cd /home/deploy/michaelschiemer/current && docker compose logs -f'
+
+# Specific service
+ssh deploy@94.16.110.151 'cd /home/deploy/michaelschiemer/current && docker compose logs -f php'
+```
+
+### System Monitoring
+
+```bash
+# Disk usage
+ansible -i inventories/production/hosts.yml web_servers -b -a "df -h /home/deploy/michaelschiemer"
+
+# Release directory sizes
+ansible -i inventories/production/hosts.yml web_servers -b -a "du -sh /home/deploy/michaelschiemer/releases/*"
+
+# Container status
+ansible -i inventories/production/hosts.yml web_servers -b -a "docker ps"
+```
+
+## Configuration
+
+### Shared Directories
+
+Konfiguriert in `deploy-rsync-based.yml`:
+
+```yaml
+shared_dirs:
+  - storage/sessions
+  - public/uploads
+
+shared_files:
+  - .env.production
+```
+
+**Hinweis**: `storage/logs`, `storage/cache`, `storage/uploads` werden via Docker Volumes verwaltet.
+
+### Rsync Exclusions
+
+Files/Directories die NICHT deployiert werden:
+
+```yaml
+rsync_excludes:
+  - .git/
+  - .github/
+  - node_modules/
+  - .env
+  - .env.local
+  - .env.development
+  - storage/
+  - public/uploads/
+  - tests/
+  - .idea/
+  - .vscode/
+  - "*.log"
+  - .DS_Store
+  - deployment/
+  - database.sqlite
+  - "*.cache"
+  - .php-cs-fixer.cache
+  - var/cache/
+  - var/logs/
+```
+
+### Keep Releases
+
+Anzahl der beibehaltenen Releases:
+
+```yaml
+keep_releases: 5  # Standard: 5 Releases
+```
+
+Ändere nach Bedarf:
+```bash
+ansible-playbook ... --extra-vars "keep_releases=10"
+```
+
+## Troubleshooting
+
+### Problem: Deployment Lock existiert
+
+**Error**:
+```
+FAILED! => msg: Deployment already in progress. Lock file exists: /home/deploy/michaelschiemer/.deploy.lock
+```
+
+**Ursache**: Vorheriges Deployment wurde unterbrochen
+
+**Lösung**:
+```bash
+# Option 1: Force deployment
+ansible-playbook ... --extra-vars "force_deploy=true"
+
+# Option 2: Lock manuell entfernen
+ansible -i inventories/production/hosts.yml web_servers -b -m file \
+  -a "path=/home/deploy/michaelschiemer/.deploy.lock state=absent"
+```
+
+### Problem: Health Check schlägt fehl
+
+**Error**:
+```
+FAILED! => Deployment failed - health check returned 503. Rolled back to previous release.
+```
+
+**Diagnose**:
+```bash
+# 1. Check application logs
+ssh deploy@94.16.110.151 'cd /home/deploy/michaelschiemer/current && docker compose logs --tail=100'
+
+# 2. Check container status
+ssh deploy@94.16.110.151 'docker ps -a'
+
+# 3. Manual health check
+curl -k -v https://94.16.110.151/health/summary
+
+# 4. Check deployment log
+ssh deploy@94.16.110.151 'tail -100 /home/deploy/michaelschiemer/deploy.log'
+```
+
+**Häufige Ursachen**:
+- .env.production fehlt oder fehlerhaft
+- Database migration fehlgeschlagen
+- Docker container starten nicht
+- SSL Zertifikat Probleme
+
+### Problem: Rsync zu langsam
+
+**Symptom**: Deployment dauert mehrere Minuten
+
+**Optimierung**:
+```yaml
+# In deploy-rsync-based.yml - rsync command erweitern
+--compress             # Kompression aktiviert
+--delete-after         # Löschen nach Transfer
+--delay-updates        # Atomic updates
+```
+
+**Alternative**: Rsync via lokales Netzwerk statt Internet:
+```yaml
+# Wenn Production Server im gleichen Netzwerk
+ansible_host: 192.168.1.100  # Lokale IP statt öffentliche
+```
+
+### Problem: Git Tag nicht erkannt
+
+**Symptom**: Deployment verwendet Timestamp statt Git Tag
+
+**Diagnose**:
+```bash
+# Check ob auf getaggtem Commit
+git describe --tags --exact-match
+# Sollte: v1.2.3 (ohne Fehler)
+
+# Check ob Tag existiert
+git tag -l
+```
+
+**Lösung**:
+```bash
+# 1. Tag erstellen falls fehlend
+git tag v1.2.3
+git push origin v1.2.3
+
+# 2. Oder Tag explizit angeben
+ansible-playbook ... --extra-vars "release_tag=v1.2.3"
+```
+
+## Best Practices
+
+### 1. Always Tag Releases
+
+```bash
+# Vor Production Deployment immer Git Tag erstellen
+git tag -a v1.2.3 -m "Release v1.2.3: Feature description"
+git push origin v1.2.3
+```
+
+**Vorteile**:
+- Klare Release-Historie
+- Einfaches Rollback zu spezifischen Versionen
+- Semantic Versioning tracking
+
+### 2. Test Deployment in Staging First
+
+```bash
+# Staging deployment (separate inventory)
+ansible-playbook -i inventories/staging/hosts.yml playbooks/deploy-rsync-based.yml \
+  --extra-vars "release_tag=v1.2.3"
+
+# Nach erfolgreichen Tests → Production
+ansible-playbook -i inventories/production/hosts.yml playbooks/deploy-rsync-based.yml \
+  --extra-vars "release_tag=v1.2.3"
+```
+
+### 3. Monitor Deployment Log
+
+```bash
+# Real-time deployment monitoring
+ssh deploy@94.16.110.151 'tail -f /home/deploy/michaelschiemer/deploy.log'
+```
+
+### 4. Backup vor Major Releases
+
+```bash
+# Database backup vor Major Release
+ssh deploy@94.16.110.151 'cd /home/deploy/michaelschiemer/current && \
+  docker compose exec php php console.php db:backup'
+```
+
+### 5. Verify Health Before Release Tag
+
+```bash
+# Health check auf Staging
+curl -k https://staging.michaelschiemer.de/health/summary
+
+# Bei Erfolg → Production Tag
+git tag v1.2.3
+git push origin v1.2.3
+```
+
+## Comparison: Rsync vs Git-based
+
+### Rsync-based (Current)
+
+**Vorteile**:
+- ✅ Keine Git-Server Abhängigkeit
+- ✅ Funktioniert mit lokalem Development
+- ✅ Schnell für kleine Änderungen
+- ✅ Einfaches Setup
+- ✅ Git Tag Support ohne External Server
+
+**Nachteile**:
+- ❌ Keine Git-Historie auf Production Server
+- ❌ Erfordert lokale Build-Steps (Composer, NPM)
+- ❌ Rsync über Internet kann langsam sein
+
+### Git-based
+
+**Vorteile**:
+- ✅ Git-Historie auf Production Server
+- ✅ Atomare Releases mit Git Commits
+- ✅ Build direkt auf Production Server
+- ✅ Kein lokales Build erforderlich
+
+**Nachteile**:
+- ❌ Gitea Server muss öffentlich erreichbar sein
+- ❌ Zusätzliche Infrastruktur (Gitea)
+- ❌ SSH Key Management komplexer
+
+## Performance Optimizations
+
+### 1. Pre-built Assets
+
+Assets werden lokal gebaut → schnelleres Deployment:
+```yaml
+pre_tasks:
+  - name: Install Composer dependencies locally
+  - name: Build NPM assets locally
+```
+
+### 2. Docker Layer Caching
+
+Docker Images werden auf Production Server gecached → schnellerer Start.
+
+### 3. Shared Directories
+
+Shared directories vermeiden unnötiges Kopieren:
+- `storage/sessions`
+- `public/uploads`
+- `.env.production`
+
+### 4. Cleanup Old Releases
+
+Nur 5 Releases behalten → spart Disk Space:
+```yaml
+keep_releases: 5
+```
+

+- `rollback-git-based.yml` - Git-based Rollback Playbook
+- `inventories/production/hosts.yml` - Production Server Configuration
+
+## Zusammenfassung
+
+Das rsync-based Deployment bietet:
+- ✅ **Production-Ready** Zero-Downtime Deployment
+- ✅ **Git Tag Support** für klare Release-Historie
+- ✅ **Automatischer Rollback** bei Failures
+- ✅ **Einfaches Setup** ohne externe Dependencies
+- ✅ **Schnell und Zuverlässig** für Development und Production
+
+**Empfehlung**: Ideal für lokale Development → Production Workflows ohne zusätzliche Git-Server-Infrastruktur.

+# Native PHP 8.5 URL System
+
+**Zero-dependency URL parsing and manipulation** using native PHP 8.5 `Uri\Rfc3986\Uri` and `Uri\WhatWg\Url`.
+
+## Features
+
+✅ **Native PHP 8.5 API** - No external dependencies
+✅ **Dual Spec Support** - RFC 3986 and WHATWG URL Standard
+✅ **Smart Factory** - Automatic spec selection based on use case
+✅ **Immutable Withers** - Framework-compliant readonly pattern
+✅ **Type Safe** - Full type safety with enums and value objects
+✅ **IDNA/Punycode** - Native international domain name support
+
+## Installation
+
+**Requirement**: PHP 8.5+
+
+No composer packages needed - uses native PHP URL API!
+
+## Quick Start
+
+### Basic Usage
+
+```php
+use App\Framework\Http\Url\UrlFactory;
+
+// Automatic spec selection
+$url = UrlFactory::parse('https://example.com/path');
+
+// API Client (RFC 3986)
+$apiUrl = UrlFactory::forApiClient('https://api.example.com/users');
+
+// Browser Redirect (WHATWG)
+$redirect = UrlFactory::forBrowserRedirect('https://app.example.com/dashboard');
+```
+
+### URL Manipulation (Immutable)
+
+```php
+$url = UrlFactory::forApiClient('https://api.example.com/users');
+
+// Immutable withers return new instances
+$withAuth = $url->withUserInfo('api_key', 'secret');
+$withQuery = $url->withQuery('filter=active&sort=name');
+$withPath = $url->withPath('/v2/users');
+
+// Component access
+echo $url->getScheme();   // 'https'
+echo $url->getHost();     // 'api.example.com'
+echo $url->getPath();     // '/users'
+```
+
+### Use Case Factory Methods
+
+```php
+// API & Server-Side (RFC 3986)
+UrlFactory::forApiClient($url);        // REST, GraphQL, SOAP
+UrlFactory::forCurlRequest($url);      // cURL operations
+UrlFactory::forSignature($url);        // OAuth, AWS signing
+UrlFactory::forCanonical($url);        // SEO, duplicate detection
+
+// Browser & Client-Side (WHATWG)
+UrlFactory::forBrowserRedirect($url);  // HTTP redirects
+UrlFactory::forDeepLink($url);         // Universal links
+UrlFactory::forFormAction($url);       // HTML form actions
+UrlFactory::forClientSide($url);       // JavaScript fetch()
+```
+
+## Architecture
+
+### URL Specifications
+
+**RFC 3986** - Server-side URL handling:
+- Strict parsing rules
+- No automatic encoding
+- Preserves exact structure
+- Best for: API clients, signatures, cURL
+
+**WHATWG** - Browser-compatible URL handling:
+- Living standard (matches browsers)
+- Automatic percent-encoding
+- URL normalization
+- Best for: Redirects, deep links, forms
+
+### Components
+
+```
+src/Framework/Http/Url/
+├── Url.php                # Unified URL interface
+├── UrlSpec.php           # RFC3986 vs WHATWG enum
+├── UrlUseCase.php        # Use case categories
+├── Rfc3986Url.php        # RFC 3986 implementation
+├── WhatwgUrl.php         # WHATWG implementation
+└── UrlFactory.php        # Smart factory
+```
+
+## Examples
+
+### API Client with Authentication
+
+```php
+$apiUrl = UrlFactory::forApiClient('https://api.example.com/resource');
+$withAuth = $apiUrl->withUserInfo('api_key', 'secret_token');
+
+echo $withAuth->toString();
+// https://api_key:secret_token@api.example.com/resource
+```
+
+### URL Signature Generation
+
+```php
+$url = UrlFactory::forSignature('https://api.example.com/resource');
+$withParams = $url->withQuery('timestamp=1234567890&user_id=42');
+
+// Generate signature from canonical URL string
+$canonical = $withParams->toString();
+$signature = hash_hmac('sha256', $canonical, $secretKey);
+
+$signed = $withParams->withQuery(
+    $withParams->getQuery() . "&signature={$signature}"
+);
+```
+
+### Browser Redirect with Parameters
+
+```php
+$redirect = UrlFactory::forBrowserRedirect('https://app.example.com/login');
+$withReturn = $redirect->withQuery('return_url=/dashboard&status=success');
+
+// Browser-compatible encoding
+header('Location: ' . $withReturn->toString());
+```
+
+### Deep Link with Fallback
+
+```php
+$deepLink = UrlFactory::forDeepLink('myapp://open/article/123');
+$fallback = UrlFactory::forBrowserRedirect('https://example.com/article/123');
+
+// Try deep link first, fallback to web
+$targetUrl = $isNativeApp ? $deepLink : $fallback;
+```
+
+### IDNA/Punycode Support
+
+```php
+$unicode = UrlFactory::parse('https://例え.jp/path');
+$ascii = $unicode->toAsciiString();
+
+echo $ascii; // https://xn--r8jz45g.jp/path
+```
+
+### URL Comparison
+
+```php
+$url1 = UrlFactory::parse('https://example.com/path#frag1');
+$url2 = UrlFactory::parse('https://example.com/path#frag2');
+
+// Ignore fragment by default
+$url1->equals($url2);                    // true
+
+// Include fragment in comparison
+$url1->equals($url2, includeFragment: true);  // false
+```
+
+### Relative URL Resolution
+
+```php
+$base = UrlFactory::parse('https://example.com/base/path');
+$resolved = $base->resolve('../other/resource');
+
+echo $resolved->toString();
+// https://example.com/other/resource
+```
+
+### Spec Conversion
+
+```php
+$rfc = UrlFactory::forApiClient('https://example.com/path');
+$whatwg = UrlFactory::convert($rfc, UrlSpec::WHATWG);
+
+// Now browser-compatible with normalization
+```
+
+## Use Case Guide
+
+### When to use RFC 3986
+
+✅ REST API requests
+✅ URL signature generation (OAuth, AWS)
+✅ cURL operations
+✅ Canonical URL generation (SEO)
+✅ Webhook URLs
+✅ FTP/SFTP URLs
+
+### When to use WHATWG
+
+✅ HTTP redirects
+✅ Deep links / universal links
+✅ HTML form actions
+✅ JavaScript fetch() compatibility
+✅ Browser-side URL generation
+✅ Mobile app URLs
+
+## Testing
+
+Comprehensive Pest tests included:
+
+```bash
+./vendor/bin/pest tests/Unit/Framework/Http/Url/
+```
+
+Test coverage:
+- RFC 3986 parsing and manipulation
+- WHATWG parsing and normalization
+- Factory method selection
+- URL comparison and resolution
+- IDNA/Punycode handling
+- Immutability guarantees
+- Edge cases and error handling
+
+## Framework Integration
+
+### Readonly Pattern
+
+All URL classes are `final readonly` with immutable withers:
+
+```php
+final readonly class Rfc3986Url implements Url
+{
+    private function __construct(
+        private NativeRfc3986Uri $uri
+    ) {}
+
+    // Withers return new instances
+    public function withPath(string $path): self
+    {
+        return new self($this->uri->withPath($path));
+    }
+}
+```
+
+### Value Object Pattern
+
+URLs are value objects with value semantics:
+
+```php
+$url1 = UrlFactory::parse('https://example.com/path');
+$url2 = UrlFactory::parse('https://example.com/path');
+
+$url1->equals($url2); // true
+```
+
+### DI Container Integration
+
+Register in container initializer:
+
+```php
+final readonly class UrlServiceInitializer implements Initializer
+{
+    #[Initializer]
+    public function __invoke(): UrlService
+    {
+        return new UrlService(UrlFactory::class);
+    }
+}
+```
+
+## Performance
+
+Native PHP 8.5 implementation = **C-level performance**:
+
+- ✅ Zero external dependencies
+- ✅ No reflection overhead
+- ✅ Optimized memory usage
+- ✅ Fast parsing and manipulation
+- ✅ Native IDNA conversion
+
+## Migration from Legacy Code
+
+### Before (primitive strings)
+
+```php
+function generateApiUrl(string $baseUrl, array $params): string
+{
+    $query = http_build_query($params);
+    return $baseUrl . '?' . $query;
+}
+```
+
+### After (type-safe URLs)
+
+```php
+function generateApiUrl(Url $baseUrl, array $params): Url
+{
+    $query = http_build_query($params);
+    return $baseUrl->withQuery($query);
+}
+
+// Usage
+$apiUrl = UrlFactory::forApiClient('https://api.example.com/resource');
+$withParams = generateApiUrl($apiUrl, ['filter' => 'active']);
+```
+
+## Best Practices
+
+1. **Use factory methods** for automatic spec selection
+2. **Prefer specific use case methods** over generic parse()
+3. **Type hint with Url** for flexibility
+4. **Use equals() for comparison** instead of string comparison
+5. **Leverage immutability** - withers are safe for concurrent use
+6. **Choose correct spec** - RFC 3986 for server, WHATWG for browser
+
+## Advanced Features
+
+### Native URL Access
+
+Access underlying native PHP URL objects when needed:
+
+```php
+$url = UrlFactory::forApiClient('https://example.com');
+$nativeUri = $url->getNativeUrl(); // \Uri\Rfc3986\Uri
+```
+
+### Custom URL Schemes
+
+Both specs support custom schemes:
+
+```php
+$custom = UrlFactory::parse('myscheme://resource/path');
+echo $custom->getScheme(); // 'myscheme'
+```
+
+## Troubleshooting
+
+### Invalid URL Errors
+
+```php
+try {
+    $url = UrlFactory::parse('invalid://url');
+} catch (\InvalidArgumentException $e) {
+    // Handle parse error
+}
+```
+
+### Spec Mismatch
+
+Convert between specs when needed:
+
+```php
+$rfc = UrlFactory::forApiClient('https://example.com');
+$whatwg = UrlFactory::convert($rfc, UrlSpec::WHATWG);
+```
+
+### IDNA Issues
+
+Native PHP 8.5 handles IDNA automatically:
+
+```php
+$url = UrlFactory::parse('https://例え.jp');
+$ascii = $url->toAsciiString(); // Automatic Punycode
+```
