+<objective>
+Create deactivation form allowing providers to deactivate published jobs with required reason field, updating post status to draft.
+
+Purpose: Give providers control to remove jobs from public view when positions are filled or no longer available, while capturing business intelligence about why jobs are being deactivated.
+Output: Formidable deactivation form integrated into provider dashboard with reason capture.

+**Tech stack available:** formidable-post-creation-action, formidable-update-post, acf-field-mapping
+**Established patterns:**
+- Formidable form creation with duplicate prevention via form key
+- Post status updates via Formidable Update Post action
+- Ownership validation in frm_validate_entry hook
+- Conditional dashboard rendering based on URL parameters
+
+**Constraining decisions:**
+- Phase 03-01: Form fields map directly to ACF meta fields using Formidable's actions
+- Phase 03-02: Dashboard shows form OR listings based on URL parameters (action=X&job_id=Y)
+- Phase 03-02: Ownership validation prevents URL parameter tampering

+<task type="auto">
+  <name>Task 1: Create job deactivation form with reason field</name>
+  <files>includes/class-formidable.php</files>
+  <action>Add create_job_deactivation_form() method following established pattern from create_job_edit_form(). Check for existing form by key 'job_deactivation' to prevent duplicates. Include 2 fields: (1) deactivation_reason textarea (required, German label "Grund für Deaktivierung", description "Bitte geben Sie an, warum Sie dieses Stellenangebot deaktivieren möchten"), (2) hidden field for job_id. Configure Update Post action: post_type='job_offer', post_status='draft' (removes from public view), id_param from URL parameter 'job_id'. Map deactivation_reason field to ACF meta field 'job_deactivation_reason'. Add ownership validation hook validate_job_deactivation_ownership() following same pattern as validate_job_ownership() from Phase 03-02 - check post exists, post_type is job_offer, post_author matches current user. Submit button: "Stellenangebot deaktivieren". Success message: "Ihr Stellenangebot wurde deaktiviert." Success action: Redirect to /anbieter-dashboard/. Add get_job_deactivation_form_id() helper following established pattern.</action>
+  <verify>Check class-formidable.php contains create_job_deactivation_form(), validate_job_deactivation_ownership(), and get_job_deactivation_form_id() methods. Confirm form configured with draft status update and reason field mapping.</verify>
+  <done>Deactivation form created programmatically, ownership validation hook registered, form ID getter exists, Update Post action configured for draft status</done>
+</task>
+
+<task type="auto">
+  <name>Task 2: Add deactivate action to provider dashboard</name>
+  <files>templates/provider-dashboard.php</files>
+  <action>Add deactivate mode detection alongside existing edit mode: check for action=deactivate_job and job_id parameter. When in deactivate mode, render deactivation form section similar to edit section structure - heading "Stellenangebot deaktivieren", back link to dashboard, form shortcode with id_param={job_id}. In job listings table, add "Deaktivieren" button in Actions column only for published jobs (status === 'publish') - deactivate URL: add_query_arg with action=deactivate_job and job_id. Style deactivate button differently from edit/view buttons (use warning/destructive color like red/orange background). Follow same conditional rendering pattern as edit mode - show deactivation form OR listings, not both.</action>
+  <verify>Dashboard template includes deactivate mode detection, deactivation form section, and deactivate button for published jobs. Verify deactivate button appears only when post_status === 'publish'.</verify>
+  <done>Dashboard supports deactivation mode via URL parameters, deactivate button visible only on published jobs, form renders in place of listings when in deactivate mode</done>

+Before declaring plan complete:
+- [ ] Deactivation form exists with key 'job_deactivation'
+- [ ] Form has deactivation_reason textarea field (required)
+- [ ] Update Post action configured to set status='draft'
+- [ ] Ownership validation prevents unauthorized deactivations
+- [ ] Dashboard shows "Deaktivieren" button only for published jobs
