+**job_offer CPT registered with ownership-enforced capabilities**
+
+## Accomplishments
+
+- Custom post type 'job_offer' with German labels

+
+## Files Created/Modified
+
+- `includes/class-post-types.php` - CPT registration and capability mapping
+- `ddhh-job-manager.php` - Include post types class
+- `includes/class-ddhh-job-manager.php` - Main singleton class (prerequisite)
+- `includes/class-activator.php` - Activation handler (prerequisite)
+- `includes/class-deactivator.php` - Deactivation handler (prerequisite)
+
+## Decisions Made
+
+- Used custom capability_type 'job_offer' (not 'post') for security
+- German labels: "Jobangebot" / "Jobangebote" 
+- Archive slug: 'jobangebote'
