Subject: [PATCH 01/26] fix: resolve PCLZIP_ERR_MISSING_FILE (-4) error with
 complete download filter rewrite

- Complete rewrite of upgrader_pre_download filter to properly handle all download scenarios
- Fixed critical issue where filter could return invalid types causing WordPress PCLZIP errors
- Added robust plugin detection to ensure filter only intercepts downloads for correct plugin
- Enhanced error handling with comprehensive error messages for all failure points
- Added multiple validation checks (file size, readability, existence) before returning file

Changes:
- Stricter filter logic: maybeFixDownload() now returns false for non-target downloads
- Safety checks: Added verification of hook_extra data for specific plugin processing
- Return type enforcement: Strict string|WP_Error|false (never true or other types)
- Multi-line conditionals: Improved code formatting for WordPress Coding Standards
- Defensive programming: Added early returns for edge cases
- Minimum file size check: Validates downloaded file is at least 100 bytes

Technical improvements:
- Enhanced PHPDoc comments explaining critical return value requirements
- Better HTTP response code handling with descriptive error messages
- Improved download process with optimized settings
- Added use WP_Error statement for proper type hinting

Version: 1.1.5

 # Changelog
 
+## [1.1.5] - 2025-10-10
+### Fixed
+- **PCLZIP_ERR_MISSING_FILE (-4) Resolution**: Complete rewrite of `upgrader_pre_download` filter to properly handle all download scenarios
+- **Download Filter Return Values**: Fixed critical issue where filter could return invalid types causing WordPress to fail with PCLZIP errors
+- **Better Plugin Detection**: Added robust verification to ensure filter only intercepts downloads for the correct plugin
+- **Enhanced Error Handling**: Comprehensive error messages for all failure points in the download process
+- **File Verification**: Added multiple validation checks (file size, readability, existence) before returning downloaded file to WordPress
+
+### Changed
+- **Stricter Filter Logic**: `maybeFixDownload()` now returns `false` to let WordPress handle downloads that aren't for our plugin
+- **Safety Checks**: Added verification of `hook_extra` data to ensure we only process downloads for our specific plugin
+- **Improved Documentation**: Enhanced PHPDoc comments explaining critical return value requirements for WordPress compatibility
+- **Download Process**: Better handling of HTTP response codes and empty responses with descriptive error messages
+
+### Technical Improvements
+- **Return Type Enforcement**: Strict enforcement of `string|WP_Error|false` return types (never `true` or other types)
+- **Multi-line Conditionals**: Improved code formatting to meet WordPress Coding Standards (120 character line limit)
+- **Defensive Programming**: Added early returns for edge cases where previous filters have already handled the download
+- **Minimum File Size Check**: Validates downloaded file is at least 100 bytes before considering it valid
+
 ## [1.1.4] - 2025-08-29
 ### Added
 - **WordPress Admin Notices**: Integrated admin notification system that displays update availability after manual version checks

 # Copilot Instructions for WP GitHub Updater Package
 
+## 📋 Documentation Policy
+
+**CRITICAL: ALL documentation must be consolidated in these three files ONLY:**
+
+1. **README.md** - User-facing documentation, installation, usage examples, API reference
+2. **CHANGELOG.md** - Version history, changes, bug fixes, new features
+3. **.github/copilot-instructions.md** - This file, development guidelines and architecture
+
+**🚫 NEVER create separate documentation files:**
+- ❌ Do NOT create files like `docs/GUIDE.md`, `docs/TESTING.md`, `TROUBLESHOOTING.md`, etc.
+- ❌ Do NOT create a `docs/` directory
+- ❌ Do NOT split documentation into multiple MD files
+
+**✅ Instead:**
+- Add user documentation to appropriate sections in README.md
+- Add development/architecture notes to this copilot-instructions.md file
+- Add version changes to CHANGELOG.md
+- Use inline code comments for complex logic explanation
+
+**Rationale:** Centralized documentation is easier to maintain, search, and keep in sync with code changes.
+
+---
+
 ## Architecture Overview
 
 This is a **reusable Composer package** that provides WordPress plugin update functionality from GitHub releases. The package is designed to be integrated into various WordPress plugins, not as a standalone plugin.
 
 ## Core Technologies
 
-- **PHP 8.0+**: Modern PHP with strict typing, union types, and nullable parameters
+- **PHP 8.3+**: Modern PHP with strict typing, union types, and nullable parameters
 - **WordPress 6.0+**: WordPress update system integration via hooks and filters
 - **PSR-4 Autoloading**: Namespace-based class loading for better organization
 - **GitHub API v3**: REST API integration for release management

-#### Testing PCLZIP Error Scenarios
+**Real GitHub API Testing:**
+
+The integration tests include **real HTTP requests** to production GitHub repositories to verify actual API behavior:
+
+- ✅ Validates actual GitHub API response structure
+- ✅ Verifies caching performance (< 10ms for cached calls)
+- ✅ Tests version comparison with real releases
+- ✅ Confirms asset pattern matching with production URLs
+
+**Example: Test with Your Own Repository**
+
+```php
+// tests/Integration/MyRealAPITest.php
+public function testFetchLatestVersionFromMyRepo(): void {
+    $config = new UpdaterConfig([
+        "plugin_file" => __FILE__,
+        "github_username" => "YourUsername",
+        "github_repo" => "your-repository",
+    ]);
+    
+    $updater = new Updater($config);
+    $version = $updater->getLatestVersion();
+    
+    $this->assertNotFalse($version);
+    $this->assertMatchesRegularExpression("/^\d+\.\d+\.\d+$/", $version);
+}
+```
+
+**Test Environment Setup:**
+
+The tests use WordPress Test Suite for authentic WordPress integration:
+
+```bash
+# Install WordPress Test Suite (interactive)
+./bin/test-runner.sh install
+
+# Or manual installation
+./bin/install-wp-tests.sh wordpress_test root '' localhost latest
+```
+
+**PCLZIP Error Testing:**
 
 For testing plugins that may experience `PCLZIP_ERR_MISSING_FILE (-4)` errors, configure a custom temporary directory:
 
 ```php
-// Test configuration for PCLZIP error handling
 $config = new UpdaterConfig(
     __FILE__,
     "your-username/your-plugin",
     [
-        "text_domain" => "your-plugin",
-        "custom_temp_dir" => WP_CONTENT_DIR . "/temp", // Custom temp directory
-        // Alternative: use uploads directory
-        // "custom_temp_dir" => wp_upload_dir()["basedir"] . "/temp",
+        "custom_temp_dir" => WP_CONTENT_DIR . "/temp",
     ]
 );
 ```
 
-#### WordPress Configuration for Testing
-
-Add to your test `wp-config.php`:
-
-```php
-// Define custom temporary directory for testing
-define('WP_TEMP_DIR', ABSPATH . 'wp-content/temp');
-
-// Ensure directory exists with proper permissions
-if (!file_exists(WP_TEMP_DIR)) {
-    wp_mkdir_p(WP_TEMP_DIR);
-}
-```

+# Mock Plugin for WP GitHub Updater Tests
+
+## 📋 Descripción
+
+Este es un **plugin de prueba (fixture)** que demuestra la integración correcta del paquete `silverassist/wp-github-updater` en un entorno real de WordPress.
+
+## 🎯 Propósito
+
+El mock plugin sirve para:
+
+1. **Testing Real de WordPress**: Permite probar el updater en un entorno WordPress completo con WordPress Test Suite
+2. **Ejemplo de Integración**: Demuestra el patrón recomendado de integración del paquete
+3. **Documentación Viva**: Sirve como referencia para desarrolladores que integren el paquete
+
+## 📁 Estructura
+
+```
+tests/fixtures/mock-plugin/
+├── mock-plugin.php       # Plugin principal con integración completa
+├── readme.txt           # WordPress plugin readme
+└── README.md           # Esta documentación
+```
+
+## 🔧 Características Implementadas
+
+### ✅ Integración Completa del Updater
+
+```php
+// Configuración completa con todas las opciones
+$config = new UpdaterConfig(
+    __FILE__,
+    "SilverAssist/mock-test-repo",
+    [
+        "plugin_name" => "Mock Plugin for Testing",
+        "cache_duration" => 300, // 5 minutos para testing
+        "text_domain" => "mock-plugin",
+        "custom_temp_dir" => WP_CONTENT_DIR . "/uploads/temp",
+        // ... más opciones
+    ]
+);
+
+$updater = new Updater($config);
+```
+
+### ✅ Panel de Administración
+
+- Página de admin con información del plugin
+- Botón para check manual de actualizaciones
+- Display de versión actual y disponible
+- Integración AJAX para checks en tiempo real
+
+### ✅ Hooks de WordPress
+
+- `plugins_loaded`: Inicialización del updater
+- `admin_menu`: Menú de administración
+- `activate_*`: Limpieza de cache en activación
+- `deactivate_*`: Limpieza de cache en desactivación
+
+### ✅ AJAX Handlers
+
+- `mock_plugin_check_version`: Check manual de versión
+- Verificación de nonces y capabilities
+- Respuestas JSON formateadas
+
+## 🧪 Uso en Tests
+
+### Cargar el Mock Plugin
+
+El mock plugin se carga automáticamente en el bootstrap de WordPress Test Suite:
+
+```php
+// En tests/bootstrap.php
+function _manually_load_plugin() {
+    require_once __DIR__ . "/fixtures/mock-plugin/mock-plugin.php";
+}
+tests_add_filter("muplugins_loaded", "_manually_load_plugin");
+```
+
+### Acceder al Updater en Tests
+
+```php
+class MyTest extends WP_UnitTestCase {
+    public function testUpdater() {
+        // Obtener instancia del updater
+        $updater = mock_plugin_get_updater();
+        
+        // Verificar funcionalidad
+        $this->assertInstanceOf(Updater::class, $updater);
+        $this->assertEquals("1.0.0", $updater->getCurrentVersion());
+    }
+}
+```
+
+### Ejemplo de Test Completo
+
+Ver `tests/WordPress/MockPluginTest.php` para ejemplos completos de:
+
+- ✅ Test de inicialización
+- ✅ Test de hooks registrados
+- ✅ Test de AJAX actions
+- ✅ Test de activación/desactivación
+- ✅ Test de menu de admin
+- ✅ Test de caching con transients

+## 🚀 Ejecutar Tests con WordPress Test Suite
+
+### 1. Instalar WordPress Test Suite
+
+```bash
+./bin/install-wp-tests.sh wordpress_test root '' localhost 6.7.1
+```
+
+### 2. Ejecutar Tests de WordPress
+
+```bash
+# Todos los tests de WordPress (incluye mock plugin)
+./vendor/bin/phpunit --testsuite=wordpress
+
+# Solo tests del mock plugin
+./vendor/bin/phpunit tests/WordPress/MockPluginTest.php
+
+# Todos los tests (incluye modo WordPress si está instalado)
+./vendor/bin/phpunit
+```
+
+### 3. Verificar Salida
+
+Cuando WordPress Test Suite está disponible, verás:
+
+```
+====================================
+WP GitHub Updater Test Suite
+====================================
+Mode: WordPress Integration Tests
+WP Tests Dir: /tmp/wordpress-tests-lib
+====================================
+✓ Mock plugin loaded: /path/to/tests/fixtures/mock-plugin/mock-plugin.php
+```
+
+## 🔍 Funcionalidades para Testing
+
+### Metadata del Plugin
+
+```php
+$pluginData = get_plugin_data($pluginFile);
+
+// Retorna:
+[
+    "Name" => "Mock Plugin for WP GitHub Updater Tests",
+    "Version" => "1.0.0",
+    "Author" => "SilverAssist",
+    "RequiresWP" => "6.0",
+    "RequiresPHP" => "8.3",
+    // ...
+]
+```
+
+### Acceso Global al Updater
+
+```php
+// Obtener updater desde cualquier parte
+$updater = mock_plugin_get_updater();
+
+// O desde global
+$updater = $GLOBALS["mock_plugin_updater"];
+```
+
+### Limpieza de Cache
+
+```php
+// Limpiar cache de versiones
+delete_transient("mock-plugin_version_check");
+
+// O usar función de activación
+do_action("activate_mock-plugin/mock-plugin.php");
+```
+
+## 📝 Configuración
+
+### Opciones Configurables
+
+El mock plugin demuestra todas las opciones disponibles:
+
+```php
+[
+    "plugin_name" => "Mock Plugin for Testing",
+    "plugin_description" => "A mock plugin for WP GitHub Updater tests",
+    "plugin_author" => "SilverAssist",
+    "cache_duration" => 300,              // 5 minutos
+    "text_domain" => "mock-plugin",
+    "custom_temp_dir" => WP_CONTENT_DIR . "/uploads/temp",
+    "ajax_action" => "mock_plugin_check_version",
+    "ajax_nonce" => "mock_plugin_nonce",
+    "asset_pattern" => "mock-plugin-{version}.zip",
+    "requires_wordpress" => "6.0",
+    "requires_php" => "8.3",
+]
+```
+
+## ⚠️ Notas Importantes
+
+### No Usar en Producción
+
+Este plugin es **exclusivamente para testing** y no debe usarse en sitios de producción:
+
+- Usa un repositorio GitHub ficticio (`mock-test-repo`)
+- Cache duration muy corta (5 minutos)
+- Configuración optimizada para testing
+
+### Repositorio Ficticio
+
+El plugin apunta a `SilverAssist/mock-test-repo` que puede no existir. Para tests reales de API, deberás:
+
+1. Crear un repositorio de prueba en GitHub
+2. Actualizar la configuración en `mock-plugin.php`
+3. Crear releases de prueba en ese repositorio
+
+### Compatibilidad
+
+- **WordPress**: 6.0+
+- **PHP**: 8.3+
+- **PHPUnit**: 9.6+
+- **WordPress Test Suite**: Requerido para tests completos

Subject: [PATCH 03/26] refactor: move scripts from bin/ to scripts/ directory

- Move install-wp-tests.sh from bin/ to scripts/
- Move test-runner.sh from bin/ to scripts/
- Update all references in README.md
- Update all references in test-runner.sh
- Update all references in tests/fixtures/mock-plugin/README.md
- Remove bin/ directory

This aligns with the existing scripts directory structure that already
contains update-version-simple.sh.

Subject: [PATCH 18/26] Update shivammathur/setup-php to valid commit SHA
 v2.35.5

Replace invalid tag object SHA with actual commit SHA:
- Old: c1ab9f1d9659ca19e46e951b81596e83154238ad (tag object)
- New: bf6b4fbd49ca58e4608c9c89fba0b8d90bd2a39f (v2.35.5)

This SHA corresponds to setup-php v2.35.5 (September 2025), which is the actual commit that the v2 tag points to. The previous SHA was the annotated tag object itself, not the commit it points to.

 - **Composer Package**: Distributed via Packagist as `silverassist/wp-github-updater`
 
+## 🔒 PHPUnit Version Policy - CRITICAL
+
+**MANDATORY: PHPUnit MUST remain at version 9.6.x**
+
+### Rationale
+- **WordPress Ecosystem Standard**: PHPUnit 9.6 is the most widely used version across WordPress projects
+- **WordPress Coding Standards**: The official [WordPress Coding Standards](https://github.com/WordPress/WordPress-Coding-Standards) uses PHPUnit 9.x
+- **Yoast PHPUnit Polyfills**: Version 4.x supports PHPUnit 7.5-9.x, 11.x, and 12.x, but **NOT 10.x**
+- **Consumer Compatibility**: Most projects depending on this package use PHPUnit 9.6
+
+### Version Constraints
+```json
+{
+  "require-dev": {
+    "phpunit/phpunit": "^9.6",
+    "yoast/phpunit-polyfills": "^4.0"
+  }
+}
+```
+
+### What NOT to do
+- ❌ Do NOT upgrade PHPUnit to version 10.x (not supported by Yoast PHPUnit Polyfills)
+- ❌ Do NOT upgrade to PHPUnit 11.x or 12.x (breaks compatibility with most WordPress projects)
+- ❌ Do NOT accept Dependabot PRs that upgrade PHPUnit beyond 9.x
+
+### Configuration Files
+- **dependabot.yml**: Configured to ignore PHPUnit major version updates
+- **composer.json**: Locked to `^9.6` version constraint
+- **phpunit.xml**: Uses PHPUnit 9.6 schema reference
+
+### When to Reconsider
+Only upgrade PHPUnit when:
+1. WordPress Coding Standards officially adopts a newer version
+2. Majority of WordPress ecosystem projects have migrated
+3. All dependent projects confirm compatibility
+
 ## Project Structure

+### PHPUnit Version Policy
+
+**This package uses PHPUnit 9.6.x and MUST remain on this version.**
+
+**Why PHPUnit 9.6?**
+- ✅ **WordPress Ecosystem Standard**: Most WordPress projects use PHPUnit 9.6
+- ✅ **WordPress Coding Standards Compatible**: [WordPress Coding Standards](https://github.com/WordPress/WordPress-Coding-Standards) uses PHPUnit 9.x
+- ✅ **Yoast PHPUnit Polyfills**: Version 4.x supports PHPUnit 7.5-9.x, 11.x, 12.x, but **NOT 10.x**
+- ✅ **Consumer Compatibility**: Projects depending on this package expect PHPUnit 9.6
+
+**Do NOT upgrade to:**
+- ❌ PHPUnit 10.x (incompatible with Yoast PHPUnit Polyfills 4.x)
+- ❌ PHPUnit 11.x or 12.x (breaks compatibility with most WordPress projects)
+
+**Dependabot Configuration:**
+The `.github/dependabot.yml` file is configured to automatically ignore PHPUnit major version updates, ensuring the package remains on 9.x.
+
