+Protect job archive from public access and configure published jobs query for Elementor template.
+
+Purpose: Ensure only logged-in users (mentors/subscribers) can browse jobs, while providing query setup that Elementor templates will use.
+Output: Protected archive with access control, query configuration helper for Elementor.

+**Tech stack available:** template_redirect hook, WP_Query filters, is_user_logged_in()
+**Established patterns:**
+- Access control via template_redirect hook (Phase 02-04)
+- Custom post type with archive slug 'jobangebote' (Phase 01-02)
+- Role-based redirects to login page (Phase 02-04)
+
+**Constraining decisions:**
+- Phase 01-02: Archive slug is 'jobangebote', supports has_archive
+- Phase 02-04: Access control uses template_redirect, redirects to /anbieter-login/
+- PROJECT.md: Protected job archive (logged-in mentors only), Elementor Pro theme integration

+<task type="auto">
+  <name>Task 1: Add archive access control to existing access control class</name>
+  <files>includes/class-access-control.php</files>
+  <action>Add method protect_job_archive() that hooks template_redirect (priority 10). Check if current page is job_offer archive (is_post_type_archive('job_offer')). If yes and user NOT logged in, redirect to /anbieter-login/ with wp_safe_redirect. Register hook in existing setup_hooks() method following established pattern from protect_provider_dashboard(). This ensures mentors (subscribers) can browse jobs but public cannot access archive.</action>
+  <verify>Check class-access-control.php contains protect_job_archive() method. Verify hook registered in setup_hooks(). Confirm redirect logic uses is_post_type_archive() and is_user_logged_in().</verify>
+  <done>Archive protection method exists, hook registered, redirect logic matches provider dashboard pattern</done>
+</task>
+
+<task type="auto">
+  <name>Task 2: Create archive query helper class for Elementor integration</name>
+  <files>includes/class-archive.php, includes/class-ddhh-job-manager.php, ddhh-job-manager.php</files>
+  <action>Create new includes/class-archive.php with class DDHH_JM_Archive. Add static method setup_hooks() that registers pre_get_posts filter (priority 10). In filter callback modify_archive_query($query), check if is job_offer archive AND is main query: set post_status='publish', orderby='date', order='DESC', posts_per_page=-1 (show all published jobs). This ensures Elementor Loop Grid displays only published jobs sorted by newest first. Initialize class in class-ddhh-job-manager.php following existing pattern (DDHH_JM_Notifications::setup_hooks()). Add file_exists check and require_once in main plugin file ddhh-job-manager.php following established pattern.</action>
+  <verify>Check includes/class-archive.php exists with DDHH_JM_Archive class. Verify pre_get_posts filter registered. Confirm query modification only affects job_offer archives. Verify class initialized in main class and required in main plugin file.</verify>
+  <done>Archive query class created, filter modifies only job archives to show published posts sorted by date, class properly initialized and required</done>

+Before declaring plan complete:
+- [ ] Archive access control method exists in class-access-control.php
+- [ ] Archive query helper class exists in includes/class-archive.php
+- [ ] Both hooks registered (template_redirect and pre_get_posts)
+- [ ] Redirect targets /anbieter-login/ for consistency
+- [ ] Query modification only affects job_offer post type archives
+- [ ] Classes properly initialized following established patterns

+
+<success_criteria>
+
+- Archive protected from public access (redirect to login)
+- Logged-in users can access /jobangebote/ archive
+- Query helper ensures only published jobs shown in archive
+- Jobs sorted by date (newest first)
+- Elementor Loop Grid can use default archive query
