LW LMS: backend extension contract

For companion plugins or themes extending LW LMS from PHP: enrollment automation, certificates, progress writes, access checks, custom settings tabs, analytics, admin tooling, and integrations with WooCommerce, WooCommerce Subscriptions, or WooCommerce Memberships.

BETA NOTICE. The plugin README says the plugin is under active development and not recommended for production use. Pin a tested version and review CHANGELOG.md before upgrading. This skill is verified against local lw-lms v1.6.0.

Version deltas that matter

• v1.6.0: lw_lms_has_course_access is reachable again as the final logged-in paid-course decision after all built-in checks. AccessRepository::revoke_by_source() adds source-scoped stored-access revocation. Minimum PHP is now 8.2.
• v1.5.1: maintenance release, no functional changes.
• v1.5.0: WooCommerce Memberships access. Paid courses can link membership plans through _lw_lms_membership_plan_ids. Active members get access at read time through MembershipChecker; no DB schema change and no access row is written.
• v1.4.0: WP-CLI operational workflow added. Use lw-lms-wp-cli-operations for those commands.
• v1.4.0: lw_lms_settings_tabs filter and SettingsPage::get_settings_group() added for companion settings tabs and shared options.php saving.
• v1.4.0: course REST content is public; only lesson content remains access-gated.
• v1.3.0: enrollment/progress hook contract added or centralized: lw_lms_pre_grant, lw_lms_after_grant, lw_lms_after_revoke, ProgressRepository::mark_course_completed(), read/write splits.

v1.6.0 course-access filter contract

AccessChecker::has_course_access() now reaches lw_lms_has_course_access after the complete built-in paid-course cascade: access rows, parent subscriptions, variation subscriptions, WooCommerce Memberships, then legacy purchases. The callback receives the aggregate built-in result and has final say, so it can grant or deliberately deny logged-in paid-course access.
