Problem

Lessons, topics and quizzes with a PublishPress Statuses workflow status (Ready, In Progress and so on) don't appear in a course's front-end listing, for anyone, including administrators. The course builder shows them correctly. Steps in Draft or Pending do appear.

In Data analytics: Full-time bootcamp (6988), this hides:

• Engineering practices I (7188) and II (7206), which are Ready, with their topics and the skills check
• every extended exercises topic under Analytics fundamentals, which are In Progress
• Exploratory data analysis (7376), which is In Progress, with its topic and the Analytics fundamentals skills check (7379)

Cause

LDLMS_Course_Steps::get_step_post_statuses() (sfwd-lms/includes/classes/class-ldlms-model-course-steps.php) limits the steps query to get_post_stati( array( 'internal' => false, '_builtin' => true ) ), which is WordPress's built-in statuses only. Any step in a custom status is missing from the loaded objects, so get_lessons() and get_topics() drop it.

Fix

A new mu-plugin, cbf-learndash-workflow-statuses.php, uses the learndash_course_steps_post_status_keys filter to add the pre-publication workflow statuses: those with moderation set and without for_revision. That leaves out revision statuses, which belong to separate revision posts, and other plugins' statuses such as spam.

Visibility is unchanged. LDLMS_Model_Course::can_user_read_step() still drops unpublished steps for any viewer without read_post on them, just as it does for drafts.

Testing

I ran the filter on production in a wp eval that saved nothing:

• As an administrator, the course listing goes from 45 to 48 lessons. Every hidden lesson, topic and quiz above is listed.
• Logged out, the listing still shows only the 5 published lessons.

phpcs passes.
