CronEngine: Real Cron Scheduler

WordPress plugin that runs WP-Cron on a real schedule with CronEngine.

This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.

Install straight from GitHub with WP-CLI:

wp plugin install https://github.com/cronengine-com/wordpress-plugin/archive/refs/heads/main.zip

No built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.

Runs WP-Cron on a real schedule. CronEngine calls your site's wp-cron.php on time, and the plugin stops page views from starting cron.

The plugin's page for users is readme.txt, which is what wordpress.org shows.

Connect. Tools, CronEngine, Connect. The admin is sent to CronEngine with the site URL, a random state and a PKCE challenge (S256), signs in or signs up, and picks an interval.
Come back. CronEngine creates a cron job for https://site/wp-cron.php?doing_wp_cron and redirects to the plugin page with a one-time code. The plugin trades the code and its PKCE verifier for a site key (cew_...) and stores it in wp_options.
Run. While connected, the plugin removes add_action( 'init', 'wp_cron' ), so page views no longer start cron. Nothing is written to wp-config.php.
Safety net. Every call from CronEngine (recognised by its X-CronEngine-Execution-ID header) is noted. If none arrives for two intervals plus 30 minutes, and at least an hour, the hook is left alone and visitors run cron again until CronEngine is back.

The site key can only read and change this site's job in CronEngine. Disconnecting, from either side, deletes the job and ends the key.

define( 'CRONENGINE_APP_URL', 'https://staging.example.com' );

CronEngine refuses to call private addresses, so the site itself has to be reachable from the internet.
