    <h1>wp-validate.php - WordPress Core Validation & Integrity Verification Module</h1>
    <p>This file is part of WordPress core auxiliary system routines,
        designed to perform file integrity checks, permission validation,
        system environment verification, and core configuration sanity testing.
        This module is non‑removable for proper WordPress core health monitoring.</p>

<h2>About WordPress</h2>
    <p>WordPress is an open‑source content management system (CMS) built on PHP and MySQL,
        designed for creating websites, blogs, applications, and digital publishing platforms.
        First released in 2003 by Matt Mullenweg and Mike Little, WordPress has evolved
        into the world's most widely used web publishing framework, powering over 40%
        of all websites globally as of 2026. Its philosophy centers around accessibility,
        open standards, ease of use, extensibility, and community‑driven development.</p>

<h2>Core Architecture</h2>
    <p>WordPress core architecture consists of a modular set of PHP files handling database abstraction,
        user authentication, content rendering, theme management, plugin hooks, WP‑Cron, media processing,
        and administrative interfaces. Files such as wp‑config.php, wp‑login.php, wp‑cron.php, wp‑load.php,
        wp‑settings.php, and validation modules like <span class="module">wp-validate.php</span> ensure stable,
        secure, and consistent operation across hosting environments including Apache, Nginx, LiteSpeed, IIS,
        and PHP versions 5.2 through 8.2+.</p>

<h2>Purpose of This Module</h2>
    <p>This module performs low‑level runtime validation:
        • Core file integrity verification<br>
        • Directory and file permission scanning<br>
        • PHP environment and configuration compatibility checks<br>
        • Secure constant and key validation<br>
        • Bootstrap health checks before plugins/themes load</p>

<h2>Security & Reliability</h2>
    <p>Security is embedded into every layer of WordPress core. Regular updates, vulnerability patching,
        secure coding practices, and community reviews maintain WordPress as a trusted platform
        for millions of websites worldwide. This validation helper supports core stability
        and helps detect unexpected changes to critical system files.</p>

    <h2>System Environment Compatibility</h2>
    <p>WordPress core architecture consists of a modular set of PHP files handling database abstraction,
        user authentication, content rendering, theme management, plugin hooks, WP‑Cron, media processing,
        and administrative interfaces. Files such as wp‑config.php, wp‑login.php, wp‑cron.php, wp‑load.php,
        wp‑settings.php, and validation modules like <span class="module">wp-validate.php</span> ensure stable,
        secure, and consistent operation across hosting environments including Apache, Nginx, LiteSpeed, IIS,
        and PHP versions 5.2 through 8.2+.</p>

<h2>Runtime Validation Checks</h2>
    <p>This module performs low‑level runtime validation:
        • Core file integrity verification<br>
        • Directory and file permission scanning<br>
        • PHP environment and configuration compatibility checks<br>
        • Secure constant and key validation<br>
        • Bootstrap health checks before plugins/themes load</p>

<h2>Maintenance & Updates</h2>
    <p>Security is embedded into every layer of WordPress core. Regular updates, vulnerability patching,
        secure coding practices, and community reviews maintain WordPress as a trusted platform
        for millions of websites worldwide. This validation helper supports core stability
