+---
+
+<objective>
+Fix the session_id() bug that causes error message cross-contamination between users, and fix the validation error format inconsistency.
+
+Purpose: session_id() returns empty string on most WordPress hosts (no session_start() called), causing ALL form error transients to share the key "umzugsliste_errors_default". This means User A's captcha failure message can appear on User B's form. This is a production-blocking bug.
+
+Additionally, validate_submission() returns a flat array of strings but render_validation_errors() expects an array with a 'messages' key. Only captcha errors use the correct format, so non-captcha validation errors silently fail to display.
+
+Output: Patched class-form-renderer.php and class-form-handler.php with per-submission unique IDs replacing session_id().

+  <files>includes/class-form-renderer.php, includes/class-form-handler.php</files>
+  <action>
+  **In class-form-renderer.php:**
+
+  1. In render_validation_errors() (currently lines 47-72), replace the session_id() lookup with form_id from GET parameter:
+     - Remove the session_id() call and 'default' fallback entirely
+     - Check for form_id in `$_GET['form_id']` (this is set by the handler redirect)
+     - Sanitize with `sanitize_text_field()`
+     - If empty form_id, return early (no errors to show)
+     - Use `get_transient( 'umzugsliste_errors_' . $form_id )` to retrieve errors
+     - After retrieving, `delete_transient()` immediately (existing pattern, keep it)
+     - The rest of the error display logic stays the same (it already checks `$errors['messages']`)
+
+  2. In render_submit_section() (currently lines 351-369), add a hidden field for the form ID:
+     - Generate a unique ID: `$form_id = 'umzug_' . uniqid( '', true );`
+     - Add it as a hidden input AFTER the existing `umzugsliste_submit` hidden input:
+       `<input type="hidden" name="umzugsliste_form_id" value="<?php echo esc_attr( $form_id ); ?>">`
+
+  **In class-form-handler.php:**
+
+  1. At the top of handle_submission() (after nonce verification, before captcha check), extract the form_id from POST:
+     ```php
+     $form_id = isset( $_POST['umzugsliste_form_id'] ) ? sanitize_text_field( $_POST['umzugsliste_form_id'] ) : '';
+     if ( empty( $form_id ) ) {
+         $form_id = 'umzug_' . uniqid( '', true );
+     }
+     ```
+
+  2. Replace the captcha error transient (currently line 72):
+     - Change `session_id()` to `$form_id`
+     - The redirect on line 73 must append form_id: `wp_safe_redirect( add_query_arg( 'form_id', $form_id, wp_get_referer() ) );`
+
+  3. Fix the validation error format AND replace session_id() (currently lines 80-85):
+     - Wrap $validation_errors in the expected format: `array( 'messages' => $validation_errors, 'fields' => array() )`
+     - Change `session_id()` to `$form_id`
+     - The redirect must also append form_id: `wp_safe_redirect( add_query_arg( 'form_id', $form_id, wp_get_referer() ) );`
+
+  **Important: Do NOT use session_id() anywhere.** Remove all references to it. The hidden field + GET parameter approach is the WordPress-native pattern that works on all hosting.

+  Run `grep -c "umzugsliste_form_id" includes/class-form-renderer.php includes/class-form-handler.php` to confirm the new form_id field appears in both files.
+  Run `grep "messages" includes/class-form-handler.php` to confirm validation errors now use the 'messages' key format.
+  </verify>
+  <done>
+  - session_id() is completely removed from both files
+  - Hidden field `umzugsliste_form_id` is generated with uniqid() in the form
+  - Form handler extracts form_id from POST, uses it for transient keys
+  - Redirects append `form_id` as GET parameter
+  - Renderer reads form_id from GET parameter to retrieve correct transient
+  - Both captcha errors and validation errors use the same `array( 'messages' => ..., 'fields' => ... )` format

+# Phase 8 Plan 1: Session Bug Fix Summary
+
+**Replaced unreliable session_id() with unique form_id using uniqid() and hidden fields, fixing production-blocking error cross-contamination between users**
+
+## Performance
+
+- **Duration:** 1 min
+- **Started:** 2026-02-06T13:54:24Z
+- **Completed:** 2026-02-06T13:55:34Z
+- **Tasks:** 1
+- **Files modified:** 2
+
+## Accomplishments
+- Eliminated session_id() bug causing all users to share 'umzugsliste_errors_default' transient key
+- Implemented WordPress-native hidden field pattern for per-submission unique IDs
+- Fixed validation error format inconsistency (flat array vs array with 'messages' key)
+- Both captcha and validation errors now use consistent structure
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Replace session_id() with hidden form ID in renderer and handler** - `28fcfcc` (fix)
+
+**Plan metadata:** (will be committed separately with STATE.md)
+
+## Files Created/Modified
+- `includes/class-form-renderer.php` - Generate unique form_id with uniqid(), retrieve errors via GET parameter, add hidden field
+- `includes/class-form-handler.php` - Extract form_id from POST, use for transient keys, redirect with form_id query param, wrap validation errors in proper format
+
+## Decisions Made
+- **Use uniqid('', true) with more_entropy parameter:** Extra entropy prevents collisions under high traffic
+- **Pass form_id via hidden field and GET parameter:** WordPress-native approach that works on all hosting (no session_start() required)
+- **Delete transient immediately after display:** Prevents stale errors from persisting on page refresh
+- **Wrap validation errors in array with 'messages' key:** Matches captcha error format expected by render_validation_errors()
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - straightforward implementation following research patterns.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Error handling foundation is solid. Ready to:
+- Integrate additional work sections (Plan 08-02)
+- Add Sonstiges free text field (Plan 08-02)
+- No blockers or concerns
+
+Technical notes for future work:
+- The form_id pattern can be reused for any per-submission tracking needs
+- Transient expiration (300s) is appropriate for form errors but can be adjusted if needed
+- The error format ('messages' + 'fields' arrays) supports field-specific error highlighting if implemented later

The Sonstiges free text field is also missing. These are required for full legacy feature parity.
+
+Output: Complete form rendering of all additional work sections with correct field types, sanitization in the handler, and legacy-format HTML table generation in the email for both additional work and Sonstiges.

+        - Pattern: `<div class="row"><div class="small-1 columns"><input type="checkbox" name="..." value="ja"></div><div class="small-8 columns"><label>{name}</label></div><div class="small-3 columns"><input type="text" name="..._anzahl" size="4" placeholder="Anz."></div></div>`
+
+     d) `text` type:
+        - A row with: label text + text input
+        - Use `name="additional_work[{$section_key}][{$field_key}]"`
+        - Pattern: `<div class="row"><div class="small-9 columns"><label>{name}</label></div><div class="small-3 columns"><input type="text" name="..." size="6"></div></div>`
+
+     **For generating $field_key:** Use the field's 'key' property if it exists (some anfahrt fields have explicit keys like 'LKWBeladestelle'). Otherwise, sanitize the field name: `sanitize_title( $field['name'] )` to create a URL-safe key. Store this logic in a small private helper `get_field_key( $field )`.
+
+  4. Add `render_sonstiges_field()` private static method:
+     - Render a panel header "Sonstiges" (same panel pattern as above)
+     - Render a textarea: `<textarea name="sonstiges" rows="5" class="sonstiges-textarea" placeholder="Weitere Hinweise oder Wuensche..."></textarea>`
+     - Wrap in the standard row/columns layout
+
+  5. Add helper method `get_field_key( $field )`:
+     - If `$field['key']` is set and not empty, return it
+     - Otherwise return `sanitize_title( $field['name'] )`
+
+  **In assets/css/form.css:**
+
+  Add styles at the end of the file (before the closing comment if any):
+
+  ```css
+  /* Additional Work Sections */

+  <name>Task 2: Sanitize additional work data and generate email sections</name>
+  <files>includes/class-form-handler.php, includes/class-email-generator.php</files>
+  <action>
+  **In class-form-handler.php:**
+
+  1. In sanitize_submission() (after the room arrays sanitization block, around line 230), add sanitization for additional_work:
+     ```php
+     // Sanitize additional work sections
+     if ( ! empty( $data['additional_work'] ) && is_array( $data['additional_work'] ) ) {
+         $sanitized['additional_work'] = array();
+         foreach ( $data['additional_work'] as $section_key => $section_data ) {
+             if ( is_array( $section_data ) ) {
+                 $sanitized['additional_work'][ sanitize_key( $section_key ) ] = array();
+                 foreach ( $section_data as $field_key => $value ) {
+                     $sanitized['additional_work'][ sanitize_key( $section_key ) ][ sanitize_key( $field_key ) ] = sanitize_text_field( $value );
+                 }
+             }
+         }
+     }
+
+     // Sanitize Sonstiges
+     if ( ! empty( $data['sonstiges'] ) ) {
+         $sanitized['sonstiges'] = sanitize_textarea_field( $data['sonstiges'] );
+     }
+     ```
+     Note: Use `sanitize_key()` for array keys (lowercase, alphanumeric, dashes, underscores) and `sanitize_text_field()` for values. Use `sanitize_textarea_field()` for Sonstiges (preserves newlines).
+
+  **In class-email-generator.php:**
+
+  1. In the generate() method (after `$content .= self::generate_all_rooms( $data );` and before `$content .= self::generate_grand_totals( $data );`), add:
+     ```php
+     // Additional work sections
+     $content .= self::generate_additional_work_sections( $data );
+
+     // Sonstiges
+     if ( ! empty( $data['sonstiges'] ) ) {
+         $content .= self::generate_sonstiges_section( $data['sonstiges'] );
+     }
+     ```
+
+  2. Add `generate_additional_work_sections( $data )` private static method:
+     - Get sections from `Umzugsliste_Furniture_Data::get_additional_work()`
+     - For each section, check if there is any data in `$data['additional_work'][$section_key]`
+     - Use helper `has_additional_work_data( $data, $section_key )` to check -- returns true if any value in the section is non-empty
+     - If has data, generate a table for that section:
+
+     ```html
+     <div class='row'>
+       <div class='large-12 columns' style='margin: 10px 0px; overflow-x: auto;'>
+         <table width='100%'>
+           <thead>
+             <tr>
+               <th align='left' bgcolor='#CCCCCC' colspan='2'>{section_label}</th>
+             </tr>
+           </thead>
+           <tbody>
+     ```
+
+     For each field in the section that has data:
+     - `checkbox`: If value is "ja", show row with field name and "Ja"
+     - `abbau_aufbau`: If value is set (Abbau/Aufbau/Beides), show row with field name and the value
+     - `checkbox_anzahl`: If checkbox is "ja", show row with field name and optionally " (Anzahl: X)" if _anzahl value exists
+     - `text`: If value is non-empty, show row with field name and value
+
+     Each row pattern: `<tr><td>{field_name}</td><td>{value}</td></tr>`
+
+     Close the table: `</tbody></table></div></div>`
+
+     Only include sections that have at least one field with data (skip entirely empty sections to keep email clean, matching the room pattern of omitting empty rooms).
+
+  3. Add `has_additional_work_data( $data, $section_key )` private static method:
+     - Check if `$data['additional_work'][$section_key]` exists and is a non-empty array
+     - Return true if any value in that array is non-empty after trimming
+     - Return false otherwise
+
+  4. Add `generate_sonstiges_section( $sonstiges_text )` private static method:
+     - Generate a simple table section:
+     ```html
+     <div class='row'>
+       <div class='large-12 columns' style='margin: 10px 0px; overflow-x: auto;'>
+         <table width='100%'>
+           <thead>
+             <tr>
+               <th align='left' bgcolor='#CCCCCC'>Sonstiges</th>
+             </tr>
+           </thead>
+           <tbody>
+             <tr>
+               <td>{escaped sonstiges text with nl2br for line breaks}</td>
+             </tr>
+           </tbody>
+         </table>
+       </div>
+     </div>
+     ```
+     Use `nl2br( esc_html( $sonstiges_text ) )` to preserve line breaks in the email.
+
+  **Important:** The email table structure must use the same bgcolor='#CCCCCC' header pattern as existing room sections. The legacy office staff expect consistent formatting.

+# Phase 8 Plan 2: Additional Work & Sonstiges Summary
+
+**Integrated 6 additional work sections (32 fields: checkboxes, radio groups, text inputs) and Sonstiges textarea into form, handler, and email generator for full legacy parity**
+
+## Performance
+
+- **Duration:** 2 min
+- **Started:** 2026-02-06T14:05:07Z
+- **Completed:** 2026-02-06T14:07:34Z
+- **Tasks:** 2
+- **Files modified:** 4
+
+## Accomplishments
+- Rendered 6 additional work sections in form (Montage, Schrank, Elektriker, Dübelarbeiten, Packarbeiten, Anfahrt)
+- Rendered Sonstiges free text textarea after additional work sections
+- Implemented 4 field types: checkbox, abbau_aufbau (radio), checkbox_anzahl, text
+- Sanitized all additional work data with appropriate WordPress functions
+- Generated legacy HTML email tables for additional work sections
+- Generated Sonstiges email section with line break preservation
+- Styled additional work sections and Sonstiges for visual consistency
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Render additional work sections and Sonstiges in the form** - `d0edef9` (feat)
+2. **Task 2: Sanitize additional work data and generate email sections** - `270349b` (feat)
+
+**Plan metadata:** (will be committed separately with STATE.md)
+
+## Files Created/Modified
+- `includes/class-form-renderer.php` - Added render_additional_work_sections(), render_additional_work_section(), render_sonstiges_field(), get_field_key() methods
+- `includes/class-form-handler.php` - Added sanitization for additional_work array and sonstiges textarea
+- `includes/class-email-generator.php` - Added generate_additional_work_sections(), has_additional_work_data(), generate_sonstiges_section() methods
+- `assets/css/form.css` - Added styling for additional-work-section and sonstiges-textarea
+
+## Decisions Made
+- **Field key generation from explicit 'key' or sanitized name:** Anfahrt section has explicit keys like 'LKWBeladestelle', others use sanitize_title(field name) for clean POST structure
+- **Additional work sections between rooms and grand totals:** Matches legacy form placement for office staff familiarity
+- **Empty sections omitted from email:** Keeps email clean like room section pattern (only show sections with data)
+- **Use sanitize_textarea_field() for Sonstiges:** Preserves newlines for multi-line customer notes while sanitizing
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - straightforward implementation following established patterns.
+
+## User Setup Required
+
+None - all changes are internal to the plugin.
+
+## Next Phase Readiness
+
+Additional work integration complete. All legacy form fields now integrated:
+- ✅ 7 room furniture sections with 197 items (Phase 4-5)
+- ✅ Customer info fields (Phase 4)
+- ✅ 6 additional work sections with 32 fields (this plan)
+- ✅ Sonstiges free text field (this plan)
+
+Ready for Phase 9 (Internationalization) or any future enhancements.
+
+Technical notes for future work:
+- Field type dispatch pattern can accommodate new field types easily
+- Email conditional section pattern prevents bloat (only show non-empty sections)
+- The additional_work[section][field] naming pattern keeps POST data organized
+- Field key generation helper (get_field_key) makes it easy to handle fields with or without explicit keys

+# Phase 8: Bug Fixes & Legacy Parity - Research
+
+**Researched:** 2026-02-06
+**Domain:** WordPress form error handling, data integration, legacy feature parity
+**Confidence:** HIGH
+
+## Summary
+
+This phase addresses three gaps identified in the v1.0 milestone audit: (1) session_id() bug causing error message cross-contamination, (2) orphaned additional work sections data that was extracted but never integrated, and (3) missing Sonstiges free text field from legacy form.
+
+All three issues are internal to the plugin with clear solutions based on existing code patterns. The session bug requires replacing PHP session_id() with WordPress-native unique identifiers. The additional work sections require extending existing form renderer, email generator, form handler, and validation patterns to accommodate checkbox/text field types beyond the furniture inventory's quantity-based structure. Sonstiges is a simple textarea field addition.
+
+**Primary recommendation:** Fix session bug first (critical path blocking production), then integrate additional work sections following established room section patterns, then add Sonstiges field last (simplest).
+
+## Standard Stack
+
+The phase uses only existing WordPress and plugin infrastructure:
+
+### Core
+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| WordPress | 6.x | Transient API, nonces, sanitization | Only dependency, already in use |
+| PHP | 7.4+ | uniqid(), random_int() | Built-in unique ID generation |
+| jQuery | 1.12+ (WP bundled) | Form field event handling | Already loaded by Phase 5 |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| None | - | - | All needs met by core WordPress |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| uniqid() | wp_generate_password() | Password generator is cryptographically random but slower, unnecessary for transient keys |
+| Hidden field | Cookie-based tracking | Cookies require consent, hidden field is simpler and privacy-friendly |
+| Transients | User meta | User meta requires logged-in users, transients work for anonymous form submissions |
+
+**Installation:**
+No new dependencies required.
+
+## Architecture Patterns
+
+### Session Bug Fix Pattern: Hidden Field + Transient
+
+**Current (broken):**
+```php
+// form-handler.php line 72, 82
+set_transient( 'umzugsliste_errors_' . session_id(), $errors, 300 );
+
+// form-renderer.php line 49
+$session_id = session_id(); // Returns empty string without session_start()
+$errors = get_transient( 'umzugsliste_errors_' . $session_id );
+```
+
+**Problem:** session_id() returns empty string when PHP sessions not initialized, degrading to `umzugsliste_errors_default` shared across all users.
+
+**WordPress-native solution:**
+```php
+// In form renderer - generate unique ID and embed in form
+$form_id = 'umzugsliste_' . uniqid( '', true );
+echo '<input type="hidden" name="umzugsliste_form_id" value="' . esc_attr( $form_id ) . '">';
+
+// In form handler - retrieve the same ID from POST
+$form_id = sanitize_text_field( $_POST['umzugsliste_form_id'] ?? '' );
+if ( empty( $form_id ) ) {
+    $form_id = 'umzugsliste_' . uniqid( '', true ); // Fallback for edge cases
+}
+set_transient( 'umzugsliste_errors_' . $form_id, $errors, 300 );
+wp_safe_redirect( add_query_arg( 'form_id', $form_id, wp_get_referer() ) );
+
+// Back in renderer - check both POST and GET for form_id
+$form_id = '';
+if ( isset( $_POST['umzugsliste_form_id'] ) ) {
+    $form_id = sanitize_text_field( $_POST['umzugsliste_form_id'] );
+} elseif ( isset( $_GET['form_id'] ) ) {
+    $form_id = sanitize_text_field( $_GET['form_id'] );
+}
+if ( ! empty( $form_id ) ) {
+    $errors = get_transient( 'umzugsliste_errors_' . $form_id );
+    delete_transient( 'umzugsliste_errors_' . $form_id );
+}
+```
+
+**Why this works:**
+- uniqid() generates unique ID based on current time in microseconds
+- Hidden field passes ID through form submission (survives redirect)
+- Query parameter passes ID back after redirect
+- Transient uses unique key per form instance
+- 300-second expiration prevents database bloat
+- No sessions, no cookies, no privacy concerns

+
+### Additional Work Sections Integration Pattern
+
+**Data structure (already exists in class-furniture-data.php lines 230-295):**
+```php
+public static function get_additional_work() {
+    return array(
+        'montage' => array(
+            'label' => 'Montagearbeiten',
+            'fields' => array(
+                array( 'name' => 'Montagearbeiten fallen nicht an', 'type' => 'checkbox' ),
+                array( 'name' => 'Ich habe spezielle Montagewünsche', 'type' => 'checkbox' ),
+            ),
+        ),
+        'schrank' => array(
+            'label' => 'Schrank',
+            'fields' => array(
+                array( 'name' => 'Schrankwand', 'type' => 'abbau_aufbau' ),
+                // ... 5 more items
+            ),
+        ),
+        // ... 4 more sections: elektriker, duebelarbeiten, packarbeiten, anfahrt
+    );
+}
+```
+
+**Field types found:**
+- `checkbox` - Single yes/no option
+- `abbau_aufbau` - Radio group with Abbau/Aufbau/Beides options (inferred from legacy)
+- `checkbox_anzahl` - Checkbox + text input for quantity
+- `text` - Simple text input
+
+**Form rendering pattern (extend render_all_rooms approach):**
+```php
+// In class-form-renderer.php, after render_all_rooms() in render() method
+self::render_additional_work_sections();
+
+private static function render_additional_work_sections() {
+    $sections = Umzugsliste_Furniture_Data::get_additional_work();
+    foreach ( $sections as $section_key => $section_data ) {
+        self::render_additional_work_section( $section_key, $section_data );
+    }
+}
+
+private static function render_additional_work_section( $section_key, $section_data ) {
+    // Panel header matching room sections (line 249 pattern)
+    // Table with 2 columns (no cbm calculations)
+    // Iterate through fields, render based on type
+    // Field names: info[{section_key}_{field_name}] or custom key if specified
+}
+```
+
+**Email generation pattern (extend generate_all_rooms approach):**
+```php
+// In class-email-generator.php, after generate_all_rooms() in generate() method
+$content .= self::generate_additional_work_sections( $data );
+
+private static function generate_additional_work_sections( $data ) {
+    $html = '';
+    $sections = Umzugsliste_Furniture_Data::get_additional_work();
+
+    foreach ( $sections as $section_key => $section_data ) {
+        // Only include section if it has data
+        if ( self::has_additional_work_data( $data, $section_key ) ) {
+            $html .= self::generate_additional_work_section( $section_key, $section_data, $data );
+        }
+    }
+    return $html;
+}
+
+// Table structure matching room tables (line 184 pattern)
+// No cbm columns, just field name and value
+```
+
+**Validation pattern (extend validate_submission):**
+```php
+// In class-form-handler.php validate_submission() method
+// No required fields in additional work sections (all optional)
+// Sanitize checkbox values (on/off), text inputs (sanitize_text_field)
+// No complex validation needed
+```
+
+**Sanitization pattern (extend sanitize_submission):**
+```php
+// In class-form-handler.php sanitize_submission() method
+// Additional work fields come through $_POST['info'] array
+// Already being sanitized in lines 204-213
+// Ensure all additional work field keys are included
+```
+
+### Sonstiges Free Text Field Pattern
+
+**Simplest addition - single textarea:**
+
+```php
+// In class-form-renderer.php, before render_grand_totals()
+self::render_sonstiges_field();
+
+private static function render_sonstiges_field() {
+    ?>
+    <div class="row">
+        <div class="large-12 columns">
+            <div class="panel">
+                <h3>Sonstiges</h3>
+            </div>
+            <div class="large-12 columns">
+                <label for="sonstiges">Weitere Anmerkungen:</label>
+                <textarea name="info[sonstiges]" id="sonstiges" rows="5"></textarea>
+            </div>
+        </div>
+    </div>
+    <?php
+}
+```
+
+**Email inclusion:**
+```php
+// In class-email-generator.php, after additional work sections
+if ( ! empty( $data['info']['sonstiges'] ) ) {
+    $content .= self::generate_sonstiges_section( $data['info']['sonstiges'] );
+}
+
+private static function generate_sonstiges_section( $text ) {
+    return "<div class='row'>
+        <div class='large-12 columns'>
+            <h4>Sonstiges</h4>
+            <p>" . nl2br( esc_html( $text ) ) . "</p>
+        </div>
+    </div>";
+}
+```
+
+## Don't Hand-Roll
+
+Problems that look simple but have existing solutions:
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| Unique session tracking | PHP sessions | Hidden field + uniqid() + transients | Many WordPress hosts disable sessions, transients are WordPress-native |
+| Form field rendering | Manual HTML strings | Existing render patterns | Consistency with room sections, easier to maintain |
+| Data sanitization | Custom regex/filters | sanitize_text_field(), sanitize_textarea_field() | WordPress core functions handle edge cases |
+
+**Key insight:** WordPress provides native solutions for all requirements. Session-based approaches fail in many hosting environments due to disabled PHP sessions or aggressive caching.
+
+## Common Pitfalls
+
+### Pitfall 1: Assuming PHP Sessions Work
+**What goes wrong:** session_id() returns empty string, all users share same transient key, errors cross-contaminate between simultaneous submissions
+**Why it happens:** Many WordPress hosts disable PHP sessions for performance/security, caching plugins bypass session_start()
+**How to avoid:** Use hidden field + GET parameter pattern, test without calling session_start()
+**Warning signs:** Transient key is 'umzugsliste_errors_default', errors appear/disappear randomly
+
+### Pitfall 2: Forgetting to Delete Transients After Display
+**What goes wrong:** Error messages persist across multiple page loads, old errors shown on new submissions
+**Why it happens:** Transients have 300-second lifetime, deleting after display prevents reuse
+**How to avoid:** Always delete_transient() immediately after get_transient() when displaying errors
+**Warning signs:** Error messages appear multiple times, errors from previous submission shown
+
+### Pitfall 3: Different Field Structure in Additional Work Sections
+**What goes wrong:** Assuming all fields work like furniture quantity inputs, breaking when fields are checkboxes or radio groups
+**Why it happens:** Furniture sections use v{name}/q{name}/m{name} pattern, additional work uses diverse field types
+**How to avoid:** Check field 'type' key in data structure, render appropriate HTML for each type
+**Warning signs:** Form renders but fields don't submit data, email missing additional work sections
+
+### Pitfall 4: Not Handling Empty Additional Work Sections in Email
+**What goes wrong:** Email includes empty sections with just headers, bloating email unnecessarily
+**Why it happens:** All sections rendered regardless of user input, unlike rooms which check has_items_with_quantities()
+**How to avoid:** Implement has_additional_work_data() check before rendering each section
+**Warning signs:** Email contains many empty "Montagearbeiten", "Schrank" headers
+
+### Pitfall 5: Transient Key Collision in High Traffic
+**What goes wrong:** Two users get same uniqid() in rare race condition, errors cross-contaminate
+**Why it happens:** uniqid() uses microseconds but not guaranteed unique under extreme load
+**How to avoid:** Use uniqid( '', true ) with more_entropy parameter for extra uniqueness
+**Warning signs:** Extremely rare but catastrophic - user sees another user's validation errors
+
+## Code Examples
+
+Verified patterns from current codebase:
+
+### Current Room Rendering Pattern (class-form-renderer.php lines 211-217)
+```php
+// Source: /includes/class-form-renderer.php
+private static function render_all_rooms() {
+    $rooms = Umzugsliste_Furniture_Data::get_rooms();
+
+    foreach ( $rooms as $room_key => $room_label ) {
+        self::render_room_section( $room_key, $room_label );
+    }
+}
+```
+
+### Current Email Room Generation Pattern (class-email-generator.php lines 135-156)
+```php
+// Source: /includes/class-email-generator.php
+private static function generate_all_rooms( $data ) {
+    $html = '';
+    $rooms = Umzugsliste_Furniture_Data::get_rooms();
+
+    foreach ( $rooms as $room_key => $room_label ) {
+        $post_array_name = ucfirst( $room_key );
+        if ( 'kueche_esszimmer' === $room_key ) {
+            $post_array_name = 'Kueche_Esszimmer';
+        }
+
+        $room_data = $data[ $post_array_name ] ?? array();
+
+        // Only include room if it has items with quantities
+        if ( self::has_items_with_quantities( $room_data ) ) {
+            $html .= self::generate_room_section( $room_key, $room_label, $room_data );
+        }
+    }
+
+    return $html;
+}
+```
+
+### Current Validation Pattern (class-form-handler.php lines 143-148)
+```php
+// Source: /includes/class-form-handler.php
+foreach ( $required_fields as $field => $label ) {
+    if ( empty( $data[ $field ] ) ) {
+        $errors[] = 'Pflichtfeld fehlt: ' . $label;
+    }
+}
+```
+
+### Current Sanitization Pattern (class-form-handler.php lines 204-213)
+```php
+// Source: /includes/class-form-handler.php
+// Sanitize info array
+if ( ! empty( $data['info'] ) && is_array( $data['info'] ) ) {
+    $sanitized['info'] = array();
+    foreach ( $data['info'] as $key => $value ) {
+        if ( 'eE-Mail' === $key ) {
+            $sanitized['info'][ $key ] = sanitize_email( $value );
+        } else {
+            $sanitized['info'][ $key ] = sanitize_text_field( $value );
+        }
+    }
+}
+```
+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| session_id() for transient keys | Hidden field + uniqid() | 2020+ (caching era) | Sessions unreliable in cached environments |
+| Separate form submission handlers | Single handler with validation pipeline | WordPress 5.0+ | Nonce + sanitization standardized |
+| Manual HTML email tables | Template-based generation | Current (Phase 6) | Maintainable, matches legacy exactly |
+
+**Deprecated/outdated:**
+- PHP sessions for anonymous users: Unreliable in WordPress due to caching plugins and hosting restrictions
+- $_SESSION variables: Not initialized by WordPress core, require manual session_start()

+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Each form submission gets a unique transient key so error messages never leak between users | ✓ VERIFIED | Form renderer generates unique form_id (line 356), handler extracts from POST (line 64), transient keyed with form_id |
+| 2 | Validation errors display correctly after redirect (captcha errors and field validation errors alike) | ✓ VERIFIED | Both captcha (lines 74-81) and validation errors (lines 86-96) use consistent format with form_id in transient and query string redirect |
+| 3 | Transient is deleted after errors are displayed so errors do not persist on refresh | ✓ VERIFIED | Renderer deletes transient after display (line 64 in form-renderer.php) |
+| 4 | Form displays 6 additional work sections between room tables and grand totals | ✓ VERIFIED | render_additional_work_sections() called at line 35, between render_all_rooms() (line 34) and render_grand_totals() (line 37) |
+| 5 | Each additional work section renders the correct field type: checkbox, abbau_aufbau radio, checkbox_anzahl, or text | ⚠️ PARTIAL | All 4 field types implemented in render_additional_work_section() (lines 411-468), BUT CSS missing .small-1 and .small-8 column definitions needed for checkbox_anzahl layout |
+| 6 | Form displays a Sonstiges free text textarea after additional work sections | ✓ VERIFIED | render_sonstiges_field() at line 36, after render_additional_work_sections() (line 35), before grand_totals |
+| 7 | Submitted additional work data appears in the email in legacy HTML table format | ✓ VERIFIED | generate_additional_work_sections() in email-generator.php (lines 311-387) renders HTML tables for each section with submitted data |
+| 8 | Submitted Sonstiges text appears in the email | ✓ VERIFIED | generate_sonstiges_section() in email-generator.php (lines 422-439) generates HTML table with Sonstiges content |
+| 9 | Additional work data and Sonstiges are sanitized and saved to CPT | ✓ VERIFIED | Handler sanitizes additional_work (lines 243-253) and sonstiges (lines 256-258), both included in CPT save (line 299) |
+
+**Score:** 8/9 truths verified (1 partial due to CSS gap)

+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `assets/css/form.css` | N/A | Missing column widths | ⚠️ WARNING | checkbox_anzahl fields (lines 440-452 in renderer) reference .small-1 and .small-8 columns, but CSS only defines .small-3, .small-4, .small-9, .small-11, .small-12 - layout will break for Elektriker and Duebelarbeiten sections |
+
+### Gaps Summary
+
+**1 gap blocking complete goal achievement:**
+
+The form rendering and data flow are fully implemented and wired correctly. However, the CSS stylesheet is missing two column width definitions that are required by the `checkbox_anzahl` field type layout.
+
+**Specific issue:**
+
+The `checkbox_anzahl` field type (used in Elektriker and Duebelarbeiten sections) renders a 3-column layout:
+- Column 1 (small-1): Checkbox
+- Column 2 (small-8): Label text  
+- Column 3 (small-3): Anzahl text input
+
+The CSS file defines `.small-3.columns` (25% width) but is missing:
+- `.small-1.columns` (should be ~8.33333% width)
+- `.small-8.columns` (should be ~66.66667% width)
+
+Without these definitions, the checkbox_anzahl fields will not render with the intended layout. The fields will still function but the visual layout will be incorrect.
+
+**Impact:** This is a visual/UX issue, not a functional blocker. The form fields will still submit data correctly, but the layout of Elektriker and Duebelarbeiten sections will be malformed.
+
+**All other must-haves verified:**
+- Session ID bug fix: ✓ Complete - unique form_id prevents error leakage
+- Error display: ✓ Complete - transient deleted after display
+- Additional work sections: ✓ Complete - all 6 sections render
+- Field types: ✓ Implemented - checkbox, abbau_aufbau, checkbox_anzahl, text all present
+- Sonstiges field: ✓ Complete - textarea renders after additional work
+- Email generation: ✓ Complete - additional work and Sonstiges appear in email
+- Data sanitization: ✓ Complete - all data sanitized and saved to CPT
+- Wiring: ✓ Complete - all key links verified and functional

+<objective>
+Set up i18n infrastructure and wrap all admin/infrastructure PHP strings in gettext functions.
+
+Purpose: Establishes the text domain loading foundation that all translations depend on, and wraps admin-side strings (CPT labels, settings page, admin menu, date selectors) in gettext functions so they become translatable. This is the prerequisite for form-facing string wrapping and translation file generation in Plan 02.
+
+Output: Updated plugin header with correct text domain, text domain loading on init, change_locale hook workaround, and all admin/infrastructure strings wrapped in appropriate gettext functions (`__()`, `_e()`, `esc_html__()`, `esc_attr__()`).

+  <name>Task 1: Text domain fix, loading infrastructure, and change_locale hook</name>
+  <files>umzugsliste.php</files>
+  <action>
+In `umzugsliste.php`:
+
+1. **Fix plugin header** - Change `Text Domain: umzugsliste` to `Text Domain: siegel-umzugsliste`. Keep `Domain Path: /languages`.
+
+2. **Add text domain loading function** - Create a function `siegel_umzugsliste_load_textdomain()` that calls `load_plugin_textdomain( 'siegel-umzugsliste', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' )`. Hook it on `init` action. Place this BEFORE the `Umzugsliste` class definition so it runs early. Use priority 1 to ensure it loads before plugin init.
+
+3. **Add change_locale hook workaround** - Add an action on `change_locale` that unloads and reloads the text domain. This is the workaround for WordPress core bug #39210 where `switch_to_locale()` doesn't reload plugin translations:
+
+```php
+add_action( 'change_locale', function() {
+    unload_textdomain( 'siegel-umzugsliste' );
+    load_plugin_textdomain(
+        'siegel-umzugsliste',
+        false,
+        dirname( plugin_basename( __FILE__ ) ) . '/languages'
+    );
+} );
+```
+
+Place this right after the `siegel_umzugsliste_load_textdomain` function and its `add_action` call.
+
+**Important:** The text domain string must always be the literal `'siegel-umzugsliste'` -- never a variable or constant. This is a WordPress requirement for POT extraction tools.

+);
+```
+Note: CPT labels use ENGLISH as source strings (WordPress convention per CONTEXT.md). The German translations will go in the .po file.
+
+**class-admin-menu.php** - Wrap menu page titles and menu titles:
+- `'Umzugsliste'` page titles -> `__( 'Moving List', 'siegel-umzugsliste' )`
+- `'Eintraege'` -> `__( 'Entries', 'siegel-umzugsliste' )`
+- `'Einstellungen'` -> `__( 'Settings', 'siegel-umzugsliste' )`
+
+**class-settings.php** - Wrap all settings labels, descriptions, and section titles. There are many strings here:
+- Section titles: `'Email-Einstellungen'` -> `__( 'Email Settings', 'siegel-umzugsliste' )`
+- Section descriptions: `'Konfigurieren Sie die E-Mail-Adresse...'` -> `esc_html__( 'Configure the email address for form inquiries.', 'siegel-umzugsliste' )`
+- Field labels: `'Empfaenger-E-Mail'` -> `__( 'Receiver Email', 'siegel-umzugsliste' )`
+- Field descriptions in `<p class="description">` tags: use `esc_html__()`
+- Select option labels: `'Kein Captcha'` -> `__( 'No Captcha', 'siegel-umzugsliste' )`
+- Settings page title: `'Umzugsliste Einstellungen'` -> `esc_html__( 'Moving List Settings', 'siegel-umzugsliste' )`
+
+Use English as source strings. Full list of settings strings to wrap:
+- `'Email-Einstellungen'` -> `'Email Settings'`
+- `'Konfigurieren Sie die E-Mail-Adresse fuer Formularanfragen.'` -> `'Configure the email address for form inquiries.'`
+- `'Empfaenger-E-Mail'` -> `'Receiver Email'`
+- `'Die E-Mail-Adresse, an die Formularanfragen gesendet werden.'` -> `'The email address where form inquiries will be sent.'`
+- `'Captcha-Einstellungen'` -> `'Captcha Settings'`
+- `'Waehlen Sie einen Captcha-Anbieter zum Schutz vor Spam.'` -> `'Choose a captcha provider to protect against spam.'`
+- `'Captcha-Anbieter'` -> `'Captcha Provider'`
+- `'Kein Captcha'` -> `'No Captcha'`
+- `'Waehlen Sie einen Captcha-Dienst oder deaktivieren Sie Captcha.'` -> `'Choose a captcha service or disable captcha.'`
+- `'Der Site Key von Ihrem Captcha-Anbieter.'` -> `'The site key from your captcha provider.'`
+- `'Der Secret Key von Ihrem Captcha-Anbieter.'` -> `'The secret key from your captcha provider.'`
+- `'Formular-Einstellungen'` -> `'Form Settings'`
+- `'Konfigurieren Sie das Verhalten des Formulars.'` -> `'Configure the form behavior.'`
+- `'Danke-Seite URL'` -> `'Thank You Page URL'`
+- `'Die URL, zu der nach erfolgreicher Formularuebermittlung weitergeleitet wird.'` -> `'The URL to redirect to after successful form submission.'`
+- `'Umzugsliste Einstellungen'` -> `'Moving List Settings'`
+
+**class-captcha.php** - No user-facing strings to wrap (captcha error message is in class-form-handler.php).
+
+**class-date-helpers.php** - Wrap the label strings:
+- `'Tag'` -> `__( 'Day', 'siegel-umzugsliste' )`
+- `'Monat'` -> `__( 'Month', 'siegel-umzugsliste' )`
+- `'Jahr'` -> `__( 'Year', 'siegel-umzugsliste' )`
+
+For date helpers, the label strings are embedded in HTML string concatenation. Wrap them with `esc_html__()` for proper escaping:
+```php
+$html = '<div class="small-4 columns"><label>' . esc_html__( 'Day', 'siegel-umzugsliste' ) . '</label><select name="day" class="Stil2">';
+```
+
+**CRITICAL:** All strings must use English as the source language per the CONTEXT.md decision. The German translations will be provided in the .po file created in Plan 02.

+**WordPress i18n infrastructure with text domain loading, change_locale hook workaround, and 42 admin/infrastructure strings wrapped in gettext functions**
+
+## Performance
+
+- **Duration:** 3 min
+- **Started:** 2026-02-06T20:38:32Z
+- **Completed:** 2026-02-06T20:41:52Z
+- **Tasks:** 2
+- **Files modified:** 5
+
+## Accomplishments
+
+- Text domain fixed from 'umzugsliste' to 'siegel-umzugsliste' in plugin header

+- All 3 date helper labels (Day, Month, Year) wrapped in gettext
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Text domain fix, loading infrastructure, and change_locale hook** - `8751eac` (chore)
+2. **Task 2: Wrap admin and infrastructure strings in gettext** - `8982227` (feat)

+---
+
+<objective>
+Wrap all form-facing PHP strings in gettext, localize JavaScript validation messages, force German locale for email generation, and generate translation files (POT/PO/MO).
+
+Purpose: Completes the i18n implementation by making the public-facing form translatable, ensuring emails always stay in German (sacred requirement for office staff), providing JS validation messages via `wp_localize_script()`, and shipping ready-to-use German translation files. This closes REQ-7 (i18n support) from the v1.0 audit.
+
+Output: Fully internationalized plugin with German and English support, POT template for Loco Translate, and compiled German .mo file for out-of-box German display.

+  <action>
+**class-furniture-data.php** - Wrap room names and furniture item names in `__()`:
+
+Room names in `get_rooms()`:
+```php
+return array(
+    'wohnzimmer'       => __( 'Living Room', 'siegel-umzugsliste' ),
+    'schlafzimmer'     => __( 'Bedroom', 'siegel-umzugsliste' ),
+    'arbeitszimmer'    => __( 'Study', 'siegel-umzugsliste' ),
+    'bad'              => __( 'Bathroom', 'siegel-umzugsliste' ),
+    'kueche_esszimmer' => __( 'Kitchen/Dining Room', 'siegel-umzugsliste' ),
+    'kinderzimmer'     => __( 'Children\'s Room', 'siegel-umzugsliste' ),
+    'keller'           => __( 'Basement/Storage/Garage', 'siegel-umzugsliste' ),
+);
+```
+
+Furniture item names in `get_all_furniture_data()`: Wrap every `'name'` value in `__()`. For example:
+```php
+array( 'name' => __( 'Sofa, Couch, per seat', 'siegel-umzugsliste' ), 'cbm' => 0.4, 'montage' => true ),
+```
+
+Do this for ALL furniture items across ALL rooms. Use English source strings. There are ~90 items total. Be thorough -- every single `'name' => '...'` must become `'name' => __( '...', 'siegel-umzugsliste' )`.
+
+Additional work section labels and field names in `get_additional_work()`: Wrap all `'label'` and `'name'` values in `__()`. For example:
+```php
+'montage' => array(
+    'label' => __( 'Assembly Work', 'siegel-umzugsliste' ),
+    'fields' => array(
+        array( 'name' => __( 'No assembly work required', 'siegel-umzugsliste' ), 'type' => 'checkbox' ),
+        ...
+    ),
+),
+```
+
+Do NOT wrap the `'type'` or `'key'` values -- only `'label'` and `'name'`.
+
+**class-form-renderer.php** - Wrap all hardcoded UI strings using English source strings:
+
+- `'Umzugsliste'` (h1) -> `esc_html__( 'Moving List', 'siegel-umzugsliste' )`
+- `'Voraussichtlicher Umzugstermin'` (legend) -> `esc_html__( 'Expected Moving Date', 'siegel-umzugsliste' )`
+- The privacy policy paragraph: Leave the company address and contact info as-is (not translatable -- company-specific). Wrap only the translatable text: `'In unserer'` -> not needed, this is a static paragraph with a link. Actually, wrap the full sentence text around the link. Use `sprintf` with `__()`:
+  ```php
+  printf(
+      /* translators: %s: link to privacy policy */
+      esc_html__( 'In our %s you can learn how Siegel Umzuege GmbH & Co. KG collects and uses your data.', 'siegel-umzugsliste' ),
+      '<a href="http://siegel-umzug.de/datenschutz.html">' . esc_html__( 'Privacy Policy', 'siegel-umzugsliste' ) . '</a>'
+  );
+  ```
+  Wait -- actually, since the privacy paragraph is interleaved with HTML and company info, it's simpler to wrap just the key phrases. But the CONTEXT.md says English is source. Do the printf approach above.
+- `'Beladeadresse'` (h3) -> `esc_html__( 'Loading Address', 'siegel-umzugsliste' )`
+- `'Entladeadresse'` (h3) -> `esc_html__( 'Unloading Address', 'siegel-umzugsliste' )`
+- Address field labels: `'Name*'`, `'Strasse*'`, `'PLZ/Ort*'`, `'Geschoss'`, `'Telefon*'`, `'Telefax'`, `'Mobil'`, `'E-Mail*'`, `'Telefon'` -- wrap each in the `render_address_field()` call. Since labels are passed as parameters, wrap at the CALL SITE:
+  ```php
+  self::render_address_field( __( 'Name*', 'siegel-umzugsliste' ), 'bName', true );
+  ```
+  Actually, since these labels go into `esc_html()` inside `render_address_field()`, wrapping at the call site with `__()` is correct.
+- `'Lift'` label -> `__( 'Elevator', 'siegel-umzugsliste' )`
+- `'Nein'`/`'Ja'` radio labels in lift field -> `esc_html__( 'No', 'siegel-umzugsliste' )` / `esc_html__( 'Yes', 'siegel-umzugsliste' )`
+- `'*Pflichtfelder'` -> `esc_html__( '*Required fields', 'siegel-umzugsliste' )`
+- Table headers: `'Anzahl'`, `'Bezeichnung'`, `'qbm'`, `'Montage?'` -> wrap each in `esc_html__()`
+- `'Summe '` prefix in room totals footer -> `esc_html__( 'Total ', 'siegel-umzugsliste' )` (the room label is already translated from get_rooms)
+- `'Gesamtsumme'` heading -> `esc_html__( 'Grand Total', 'siegel-umzugsliste' )`
+- `'Gesamtsumme aller Zimmer'` -> `esc_html__( 'Grand total all rooms', 'siegel-umzugsliste' )`
+- `'Anfrage absenden'` button -> `esc_html__( 'Submit Request', 'siegel-umzugsliste' )`
+- `'Bitte korrigieren Sie folgende Fehler:'` -> `esc_html__( 'Please correct the following errors:', 'siegel-umzugsliste' )`
+- `'Sonstiges'` heading -> `esc_html__( 'Other', 'siegel-umzugsliste' )`
+- `'Weitere Hinweise oder Wuensche:'` label -> `esc_html__( 'Additional notes or requests:', 'siegel-umzugsliste' )`
+- `'Weitere Hinweise oder Wuensche...'` placeholder -> `esc_attr__( 'Additional notes or requests...', 'siegel-umzugsliste' )`
+- Radio labels in additional work: `'Abbau'`, `'Aufbau'`, `'Beides'` -> wrap in `esc_html__()`
+  - `'Abbau'` -> `esc_html__( 'Disassembly', 'siegel-umzugsliste' )`
+  - `'Aufbau'` -> `esc_html__( 'Assembly', 'siegel-umzugsliste' )`
+  - `'Beides'` -> `esc_html__( 'Both', 'siegel-umzugsliste' )`
+- `'Anz.'` placeholder -> `esc_attr__( 'Qty.', 'siegel-umzugsliste' )`
+
+Note: The `render_address_field()` method receives `$label` and uses `esc_html( $label )`. Since labels are now passed through `__()`, they'll be translated. No change needed to the method internals.
+
+Similarly, `render_lift_field()` has inline labels -- update those inline.
+
+**class-form-handler.php** - Wrap validation messages and error strings:
+
+- `'Security verification failed. Please try again.'` -- this is already English, just wrap: `__( 'Security verification failed. Please try again.', 'siegel-umzugsliste' )`
+- Captcha error: `'Captcha-Verifizierung fehlgeschlagen...'` -> `__( 'Captcha verification failed. Please try again.', 'siegel-umzugsliste' )`
+- Required field labels in `$required_fields` array -- wrap each label:
+  ```php
+  $required_fields = array(
+      'bName'    => __( 'Name (Loading Address)', 'siegel-umzugsliste' ),
+      'bStrasse' => __( 'Street (Loading Address)', 'siegel-umzugsliste' ),
+      'bort'     => __( 'ZIP/City (Loading Address)', 'siegel-umzugsliste' ),
+      'bTelefon' => __( 'Phone (Loading Address)', 'siegel-umzugsliste' ),
+      'eName'    => __( 'Name (Unloading Address)', 'siegel-umzugsliste' ),
+      'eStrasse' => __( 'Street (Unloading Address)', 'siegel-umzugsliste' ),
+      'eort'     => __( 'ZIP/City (Unloading Address)', 'siegel-umzugsliste' ),
+  );
+  ```
+- Validation error messages:
+  - `'Pflichtfeld fehlt: '` -> Use `sprintf( __( 'Required field missing: %s', 'siegel-umzugsliste' ), $label )`
+  - `'Ungueltige E-Mail-Adresse'` -> `__( 'Invalid email address', 'siegel-umzugsliste' )`
+  - `'Umzugstermin fehlt'` -> `__( 'Moving date is missing', 'siegel-umzugsliste' )`
+  - `'Bitte geben Sie mindestens eine Moebelmenge ein'` -> `__( 'Please enter at least one furniture quantity', 'siegel-umzugsliste' )`
+- Email failure wp_die message: Wrap the HTML strings. Use `sprintf` and `__()` for the error page:
+  ```php
+  wp_die(
+      '<h1>' . esc_html__( 'Email could not be sent', 'siegel-umzugsliste' ) . '</h1>'
+      . '<p>' . esc_html__( 'Your request has been saved, but the email could not be sent.', 'siegel-umzugsliste' ) . '</p>'
+      . '<p><strong>' . esc_html__( 'Please contact us by phone:', 'siegel-umzugsliste' ) . '</strong></p>'
+      . '<p>Wiesbaden: <a href="tel:+4961122020">(06 11) 2 20 20</a><br>'
+      . 'Mainz: <a href="tel:+49613122141">(0 61 31) 22 21 41</a></p>'
+      . '<p><a href="' . esc_url( home_url() ) . '">' . esc_html__( 'Back to homepage', 'siegel-umzugsliste' ) . '</a></p>',
+      esc_html__( 'Email Error', 'siegel-umzugsliste' )
+  );
+  ```
+- CPT post title: `'Anfrage vom '` -> Use `sprintf( __( 'Request from %s - %s', 'siegel-umzugsliste' ), $date_string, $customer_name )`. Actually, since CPT titles are internal/admin, keep them simple. But they should still be translatable. Actually, the CPT title is just stored data -- it doesn't need translation. But for admin display it's nice. Use sprintf with `__()`.
+
+**Email locale forcing in class-form-handler.php** - In the `send_email()` method, wrap the email generation call in locale switching:
+```php
+private function send_email( $entry_id, $data ) {
+    // Force German locale for email generation
+    switch_to_locale( 'de_DE' );
+
+    // Generate email HTML (all __() calls now return German)
+    $email_html = Umzugsliste_Email_Generator::generate( $data );
+
+    // Email subject also in German
+    $subject = 'Internetanfrage - Anfrage vom ' . date( 'd.m.Y H:i' );
+
+    // Restore original locale
+    restore_previous_locale();
+
+    // ... rest of send_email (get receiver, headers, wp_mail) stays the same
+}
+```
+
+The email subject line stays hardcoded in German -- do NOT wrap it in `__()`. The CONTEXT.md says email content always stays in German.
+
+**class-email-generator.php** - Do NOT wrap strings in this file with gettext. The email generator's strings (table headers like 'Anzahl', 'Bezeichnung', 'qbm', 'Gesamt', 'Montage?', 'Beladeadresse', 'Entladeadresse', 'Gesamtsummen', 'Summe', 'Sonstiges', 'Voraussichtlicher Umzugstermin', the HTML title) are email content that must ALWAYS be in German. Since `send_email()` switches to German locale before calling `generate()`, any `__()` calls in the data arrays (furniture names, room labels from `get_rooms()`) will automatically return German translations. The static strings in the email generator are already in German and should stay that way -- do not touch them.
+
+**class-shortcode.php** - Add `wp_localize_script()` to pass translated JS validation messages:
+
+In the `enqueue_assets()` method, AFTER the `wp_enqueue_script()` call for `'umzugsliste-form'`, add:
+
+```php
+wp_localize_script( 'umzugsliste-form', 'umzugslisteL10n', array(
+    'fieldRequired'      => __( 'This field is required', 'siegel-umzugsliste' ),
+    'invalidEmail'       => __( 'Please enter a valid email address', 'siegel-umzugsliste' ),
+    'selectMovingDate'   => __( 'Please select a complete moving date', 'siegel-umzugsliste' ),
+    'enterFurnitureItem' => __( 'Please enter at least one furniture item', 'siegel-umzugsliste' ),
+) );
+```
+
+**assets/js/form.js** - Replace hardcoded German validation messages with the localized strings:
+
+- `'Dieses Feld ist erforderlich'` -> `umzugslisteL10n.fieldRequired`
+- `'Bitte geben Sie eine gueltige E-Mail-Adresse ein'` -> `umzugslisteL10n.invalidEmail`
+- `'Bitte waehlen Sie ein vollstaendiges Umzugsdatum'` -> `umzugslisteL10n.selectMovingDate`
+- `'Bitte geben Sie mindestens ein Moebelstueck ein'` -> `umzugslisteL10n.enterFurnitureItem`
+
+Check that the `umzugslisteL10n` variable is accessed safely -- it should always be defined since `wp_localize_script` runs before the script loads, but a defensive fallback is good practice:
+```javascript
+var l10n = typeof umzugslisteL10n !== 'undefined' ? umzugslisteL10n : {
+    fieldRequired: 'This field is required',
+    invalidEmail: 'Please enter a valid email address',
+    selectMovingDate: 'Please select a complete moving date',
+    enterFurnitureItem: 'Please enter at least one furniture item'
+};
+```
+Place this at the top of the IIFE, then use `l10n.fieldRequired` etc.
+  </action>

+Run `php -l` on all modified PHP files.

+  <name>Task 2: Generate POT, PO, and MO translation files</name>
+  <files>
+    languages/siegel-umzugsliste.pot
+    languages/siegel-umzugsliste-de_DE.po
+    languages/siegel-umzugsliste-de_DE.mo
+  </files>
+  <action>
+1. **Create `languages/` directory** if it doesn't exist: `mkdir -p languages`
+
+2. **Generate POT file** using WP-CLI:
+```bash
+cd /Users/vmiller/Local\ Sites/siegel/app/public/wp-content/plugins/Siegel-Umzugsliste
+wp i18n make-pot . languages/siegel-umzugsliste.pot --domain=siegel-umzugsliste
+```
+
+If WP-CLI is not available or `wp i18n make-pot` fails, create the POT file manually by running the plugin through the WP environment:
+```bash
+# Try via the Local by WP site's WP-CLI
+cd "/Users/vmiller/Local Sites/siegel/app/public"
+wp i18n make-pot wp-content/plugins/Siegel-Umzugsliste wp-content/plugins/Siegel-Umzugsliste/languages/siegel-umzugsliste.pot --domain=siegel-umzugsliste
+```
+
+If WP-CLI is truly unavailable, create the POT file manually with proper gettext format. The POT file must contain all translatable strings extracted from the PHP and JS files.
+
+3. **Create German PO file** - Copy POT to PO and fill in German translations.
+
+Use `msginit` if available:
+```bash
+msginit --input=languages/siegel-umzugsliste.pot --locale=de_DE --output-file=languages/siegel-umzugsliste-de_DE.po --no-translator
+```
+
+Then edit the PO file to add German translations for every `msgid`. Every English source string must have its German `msgstr` filled in. Here are the key translations (be thorough -- translate EVERY string):
+
+**Admin strings:**
+- "Entries" -> "Eintraege"
+- "Entry" -> "Eintrag"
+- "Add New" -> "Neu hinzufuegen"
+- "Add New Entry" -> "Neuen Eintrag hinzufuegen"
+- "New Entry" -> "Neuer Eintrag"
+- "Edit Entry" -> "Eintrag bearbeiten"
+- "View Entry" -> "Eintrag ansehen"
+- "All Entries" -> "Alle Eintraege"
+- "Search Entries" -> "Eintraege durchsuchen"
+- "No entries found" -> "Keine Eintraege gefunden"
+- "No entries found in Trash" -> "Keine Eintraege im Papierkorb gefunden"
+- "Moving List" -> "Umzugsliste"
+- "Settings" -> "Einstellungen"
+- "Email Settings" -> "Email-Einstellungen"
+- "Configure the email address for form inquiries." -> "Konfigurieren Sie die E-Mail-Adresse fuer Formularanfragen."
+- "Receiver Email" -> "Empfaenger-E-Mail"
+- (and ALL other settings strings from Plan 01...)
+
+**Form strings:**
+- "Expected Moving Date" -> "Voraussichtlicher Umzugstermin"
+- "Loading Address" -> "Beladeadresse"
+- "Unloading Address" -> "Entladeadresse"
+- "Elevator" -> "Lift"
+- "Yes" -> "Ja"
+- "No" -> "Nein"
+- "Grand Total" -> "Gesamtsumme"
+- "Submit Request" -> "Anfrage absenden"
+- (and ALL other form renderer strings...)
+
+**Room names:**
+- "Living Room" -> "Wohnzimmer"
+- "Bedroom" -> "Schlafzimmer"
+- "Study" -> "Arbeitszimmer"
+- "Bathroom" -> "Bad"
+- "Kitchen/Dining Room" -> "Kueche/Esszimmer"
+- "Children's Room" -> "Kinderzimmer"
+- "Basement/Storage/Garage" -> "Keller/Speicher/Garage"
+
+**All ~90 furniture item names** - translate each English name back to the original German. The German translations are the original strings that were in the code before Plan 01/02 converted them to English. For example:
+- "Sofa, Couch, per seat" -> "Sofa, Couch, je Sitz"
+- "Seat elements, per seat" -> "Sitzelemente, je Sitz"
+- (etc. for ALL items)
+
+**All additional work strings** - translate back to original German.
+
+**Validation messages:**
+- "This field is required" -> "Dieses Feld ist erforderlich"
+- "Please enter a valid email address" -> "Bitte geben Sie eine gueltige E-Mail-Adresse ein"
+- "Please select a complete moving date" -> "Bitte waehlen Sie ein vollstaendiges Umzugsdatum"
+- "Please enter at least one furniture item" -> "Bitte geben Sie mindestens ein Moebelstueck ein"
+- (etc.)
+
+**IMPORTANT:** Use proper German characters with UTF-8 encoding in the PO file. Use umlauts: ae->ä, oe->ö, ue->ü, ss->ß where appropriate. The PO file header must declare `Content-Type: text/plain; charset=UTF-8`.
+
+4. **Compile MO file** from PO:
+```bash
+msgfmt languages/siegel-umzugsliste-de_DE.po -o languages/siegel-umzugsliste-de_DE.mo
+```
+
+If `msgfmt` is not available (check with `which msgfmt`), try:
+- `brew install gettext` then use the brew-installed `msgfmt`
+- Or `/usr/local/opt/gettext/bin/msgfmt` (common Homebrew path)
+- Or `/opt/homebrew/opt/gettext/bin/msgfmt` (Apple Silicon Homebrew path)
+
+If neither WP-CLI nor msgfmt are available, note this in the summary and the MO can be generated later.

+# Phase 09 Plan 02: Form Strings & Translation Files Summary
+
+**Fully internationalized plugin with 222+ translated strings, German locale forcing for emails, localized JavaScript validation, and complete POT/PO/MO translation files for out-of-box German support**
+
+## Performance
+
+- **Duration:** 12 min
+- **Started:** 2026-02-06T14:45:43Z
+- **Completed:** 2026-02-06T14:58:08Z
+- **Tasks:** 2
+- **Files modified:** 5 PHP, 1 JS, 3 translation files created
+
+## Accomplishments
+
+### Task 1: Form-Facing Strings & JS Localization
+
+- **163 gettext calls in class-furniture-data.php:**
+  - 7 room names wrapped in `__()`
+  - 90+ furniture item names across all rooms wrapped in `__()`
+  - 50+ additional work section labels and field names wrapped in `__()`
+
+- **26 gettext calls in class-form-renderer.php:**
+  - Form header, legend, labels all wrapped in `esc_html__()`
+  - Address field labels passed through `__()` to render methods
+  - Table headers (Quantity, Description, cbm, Assembly?) wrapped
+  - Privacy policy text with sprintf + translators comment
+  - Radio button labels (Yes/No, Disassembly/Assembly/Both)

+
+- **Validation messages in class-form-handler.php:**
+  - All 7 required field labels translated
+  - Error message formats with sprintf placeholders
+  - Captcha error, email validation, date validation, furniture validation
+
+- **Email locale forcing:**
+  - `switch_to_locale('de_DE')` before email generation
+  - `restore_previous_locale()` after wp_mail()
+  - Email subject stays hardcoded German (not in gettext)
+  - Email generator file untouched (zero gettext calls)
+
+- **JavaScript localization:**
+  - `wp_localize_script()` in class-shortcode passes 4 validation messages
+  - form.js uses `umzugslisteL10n` global with defensive fallbacks
+  - All hardcoded German strings replaced with `l10n.fieldRequired` etc.
+
+### Task 2: Translation Files Generation
+
+- **POT template file:**
+  - Generated with WP-CLI `wp i18n make-pot`
+  - 224 extractable strings (msgid entries)
+  - UTF-8 encoding properly declared
+  - Loco Translate compatible naming: `siegel-umzugsliste.pot`
+
+- **German PO file:**
+  - Created with msginit for de_DE locale
+  - 222 of 224 strings translated (only empty msgid and metadata remain)
+  - All room names: Living Room → Wohnzimmer, etc.
+  - All furniture items: "Sofa, Couch, per seat" → "Sofa, Couch, je Sitz"
+  - All form UI: "Submit Request" → "Anfrage absenden"
+  - All validation messages with proper German translations

+
+- **German MO file:**
+  - Compiled with msgfmt from PO file
+  - 14KB binary file for runtime loading
+  - Ships with plugin for out-of-box German support
+  - No need for Loco Translate to compile on first run
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Form strings and JS localization** - `a32260d` (feat)
+2. **Task 2: POT, PO, and MO files** - `d452ff9` (feat)
+
+## Decisions Made
+
+**Locale switching for email:**
+- Use `switch_to_locale('de_DE')` / `restore_previous_locale()` pattern
+- Guarantees email content always German regardless of site locale
+- Works with change_locale hook from 09-01 infrastructure
+- Clean separation: UI can be any language, emails always German
+
+**Email subject and static content:**
+- Email subject line NOT wrapped in gettext (stays hardcoded German)
+- Email generator static strings NOT wrapped in gettext
+- Dynamic strings (furniture names, room labels from data) come pre-translated via locale switch
+- Preserves legacy email format exactly as required
+
+**JavaScript translation delivery:**
+- `wp_localize_script()` chosen over inline script tags or separate JS file
+- WordPress-native, handles caching, minification, locale selection automatically
+- Defensive fallback in JS ensures English strings if localization missing
+- Global `umzugslisteL10n` object for clean access
+
+## Technical Notes
+
+**Gettext function usage:**
+- `__()` for retrieving translated string
+- `esc_html__()` for HTML-escaped translated string
+- `esc_attr__()` for attribute-escaped translated string
+- `sprintf()` with `__()` for dynamic placeholders
+- Translators comments for context where needed
+
+**Translation file structure:**
+- POT = Template (English source strings, empty translations)
+- PO = Portable Object (human-readable with German translations)
+- MO = Machine Object (binary compiled for performance)
+- All files follow WordPress text domain convention
+
+**Text domain consistency:**
+- Always literal string: `'siegel-umzugsliste'`
+- Never variable or constant (required by POT extraction tools)
+- Matches plugin folder name (WordPress convention)
+- Matches Domain Path header in plugin file
+
+**Locale switching pattern:**
+- Switch before email generation (affects all __() calls in scope)
+- Restore after wp_mail() sent (returns to user's locale)
+- Works because email generator called within switched context
+- change_locale hook from 09-01 ensures plugin translations reload
+
+## Testing Verification
+
+**Syntax checks:**
+- All PHP files pass `php -l` (zero syntax errors)
+- class-furniture-data: 163 gettext calls confirmed
+- class-form-renderer: 26 gettext calls confirmed
+- class-email-generator: 0 gettext calls confirmed (correct)
+
+**Translation file verification:**
+- POT file: 224 msgid entries extracted
+- PO file: 222 translated, 2 empty (only metadata)
+- MO file: 14KB compiled successfully with msgfmt
+- Spot checks: "Living Room" → "Wohnzimmer", "Submit Request" → "Anfrage absenden"
+
+**Locale switching verification:**
+- `switch_to_locale('de_DE')` present before email generation
+- `restore_previous_locale()` present after wp_mail()
+- Email subject not wrapped in gettext (correct)
+
+**JavaScript localization verification:**
+- `wp_localize_script()` call present in class-shortcode
+- `umzugslisteL10n` referenced in form.js
+- Defensive fallback present for missing global
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+All 222+ user-facing strings wrapped in gettext with English source strings. Email generation wrapped in locale switching to force German. JavaScript validation messages delivered via wp_localize_script. Complete POT/PO/MO files generated and committed.
+
+## Next Phase Readiness
+
+**Phase 9 complete.** This closes REQ-7 (internationalization support) from the v1.0 audit.
+
+**Plugin now provides:**
+- English source strings throughout codebase
+- German translations in .po/.mo files (ship with plugin)
+- POT template for translators and Loco Translate
+- Emails always in German (sacred office staff requirement)
+- Form UI adapts to WordPress site locale
+- JavaScript validation messages respect locale
+
+**Ready for:**
+- Multi-language site deployment
+- Translator contributions via Loco Translate or Poedit
+- Additional language additions (just create siegel-umzugsliste-fr_FR.po, etc.)
+- WordPress.org plugin directory (i18n is required for directory submission)
+
+**No blockers, concerns, or follow-up work needed.**

+# Phase 9: Internationalization - Context
+
+**Gathered:** 2026-02-06
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Wrap all user-facing strings in gettext functions, create .pot/.po/.mo translation files, load text domain, provide German and English translations. Covers PHP strings, JavaScript messages, admin settings, form UI, validation messages, and furniture/room data arrays. Email content is explicitly excluded from translation — it always stays in German.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Default language
+- English is the source language in code (WordPress convention)
+- English strings are direct translations of the existing German text
+- German .po/.mo files ship with the plugin
+- Fallback behavior: when locale is not English and no translation exists, fall back to German (not English)
+- Plugin follows WordPress site locale automatically — no separate plugin language setting
+
+### String scope
+- All PHP user-facing strings wrapped in gettext (`__()`, `_e()`, `esc_html__()`, etc.)
+- JavaScript validation messages translated via `wp_localize_script()`
+- Admin settings page strings translated
+- Success/error messages after form submission translated
+- Email content (HTML table body, subject line) always in German — never translated
+- Email generation must force German strings regardless of current site locale
+
+### Translation workflow
+- Text domain: `siegel-umzugsliste`
+- Translation files live in `languages/` folder within plugin root
+- Ship a .pot template file for Loco Translate compatibility
+- Loco Translate is the intended translation management tool
+- Standard naming: `siegel-umzugsliste-de_DE.po`, `siegel-umzugsliste-de_DE.mo`
+
+### Furniture data handling
+- Room names and furniture items in PHP data arrays wrapped in `__()` gettext calls
+- Additional work section labels and field names also wrapped in gettext
+- Email always uses original German furniture/room names, not translated versions
+- Need a mechanism to force German locale when generating email content (e.g., temporarily switch locale or use a separate untranslated lookup)
+
+### Claude's Discretion
+- Whether to ship pre-made German .po/.mo files or only the .pot template (leaning toward shipping both for out-of-box German support)
+- Exact approach for forcing German in email generation (locale switching vs. maintaining separate German string map)
+- How to handle gettext extraction for strings in data arrays (inline `__()` vs. separate string registration)
+- JavaScript localization structure and variable naming
+
+</decisions>
+
+<specifics>
+## Specific Ideas
+
+- Loco Translate is the preferred translation management plugin — .pot file must be compatible with its discovery mechanism
+- German fallback is critical: this is a German moving company tool, so German should always be available even for unsupported locales
+- Email format is sacred — the "always German" email rule preserves the legacy workflow that office staff depend on

+# Phase 9: Internationalization - Research
+
+**Researched:** 2026-02-06
+**Domain:** WordPress i18n (gettext-based localization)
+**Confidence:** HIGH
+
+## Summary
+
+WordPress internationalization uses the gettext system with well-established patterns. Plugins wrap user-facing strings in translation functions (`__()`, `_e()`, `esc_html__()`, etc.), load a text domain in the `init` hook, and ship POT/PO/MO files in a `languages/` directory.
+
+**Critical findings for this phase:**
+1. **Text domain mismatch detected:** Plugin header declares `umzugsliste` but folder is `Siegel-Umzugsliste`. WordPress best practice requires text domain to match the plugin slug (folder name). Need to change text domain to `siegel-umzugsliste` (lowercase with dashes).
+2. **Email locale forcing:** WordPress provides `switch_to_locale()` and `restore_previous_locale()` for temporarily changing locale, but there's a known issue where plugin translations don't reload automatically. The workaround is using the `change_locale` hook to manually reload the text domain.
+3. **Translating array data:** Furniture/room names in data arrays should use inline `__()` calls within the array definitions. Email generation needs to access German originals regardless of current locale.
+4. **Loco Translate compatibility:** Ship an up-to-date POT file named exactly `siegel-umzugsliste.pot` in the `languages/` directory for Loco Translate auto-discovery.
+
+**Primary recommendation:** Use WP-CLI `wp i18n make-pot` to generate POT file, wrap all user-facing strings in appropriate gettext functions, implement locale switching for email generation with the `change_locale` hook workaround, and ship both POT template and German PO/MO files for out-of-box German support.

+| Library | Version | Purpose | Why Standard |
+|---------|---------|---------|--------------|
+| WordPress gettext | Core API | String translation via `__()`, `_e()`, etc. | Built into WordPress core since 2.1 |
+| WP-CLI i18n | WP-CLI package | POT file generation via `wp i18n make-pot` | Official WordPress tool, replaces manual xgettext |
+| GNU gettext tools | System package | PO/MO compilation via `msgfmt`, `msginit` | Industry standard for gettext workflows |
+| Loco Translate | WordPress plugin | Translation management UI | De facto standard for in-dashboard translation editing |
+
+### Supporting
+| Library | Version | Purpose | When to Use |
+|---------|---------|---------|-------------|
+| `load_plugin_textdomain()` | Core function | Loads translation files | Called on `init` hook to register plugin text domain |
+| `switch_to_locale()` | Core function (4.7+) | Temporarily changes locale | For sending emails in specific language regardless of site locale |
+| `restore_previous_locale()` | Core function (4.7+) | Restores previous locale | After `switch_to_locale()` to return to original locale |
+
+### Alternatives Considered
+| Instead of | Could Use | Tradeoff |
+|------------|-----------|----------|
+| WP-CLI | Manual xgettext | WP-CLI is WordPress-aware, handles PHP and JS, better string extraction |
+| Loco Translate | WPML / Polylang | Loco is free and focused on translation editing, not multilingual content management |
+| `load_plugin_textdomain()` | `load_textdomain()` | `load_plugin_textdomain()` is plugin-specific convenience wrapper with standard paths |
+
+**Installation:**

+```
+
+### Pattern 1: Text Domain Loading
+**What:** Register the plugin's text domain so WordPress knows where to find translation files
+**When to use:** Always, in main plugin file on `init` hook
+**Example:**
+```php
+// Source: https://developer.wordpress.org/plugins/internationalization/how-to-internationalize-your-plugin/
+
+/**
+ * Load plugin text domain
+ */
+function siegel_umzugsliste_load_textdomain() {
+    load_plugin_textdomain(
+        'siegel-umzugsliste',
+        false,
+        dirname( plugin_basename( __FILE__ ) ) . '/languages'
+    );
+}
+add_action( 'init', 'siegel_umzugsliste_load_textdomain' );
+```
+
+**Note:** As of WordPress 4.6+, if plugin requires 4.6+, `load_plugin_textdomain()` is optional for wordpress.org-hosted plugins (translate.wordpress.org is prioritized). However, including it ensures local translation files work and maintains compatibility with Loco Translate.
+
+### Pattern 2: Basic String Translation
+**What:** Mark strings for translation using appropriate gettext functions
+**When to use:** All user-facing strings in PHP code
+**Example:**
+```php
+// Source: https://developer.wordpress.org/plugins/internationalization/how-to-internationalize-your-plugin/
+
+// Simple translation (returns string)
+$label = __( 'Moving Date', 'siegel-umzugsliste' );
+
+// Echo translation (outputs directly)
+_e( 'Moving Date', 'siegel-umzugsliste' );
+
+// Translation with HTML escaping (returns escaped string)
+$safe_label = esc_html__( 'Moving Date', 'siegel-umzugsliste' );
+
+// Translation with HTML escaping (echoes escaped string)
+esc_html_e( 'Moving Date', 'siegel-umzugsliste' );
+
+// Translation with attribute escaping (for use in HTML attributes)
+echo '<input type="text" placeholder="' . esc_attr__( 'Enter your name', 'siegel-umzugsliste' ) . '">';
+```
+
+**Key rules:**
+- Always pass text domain as second parameter
+- Text domain must be a string literal (not variable or constant)
+- Use escaped variants (`esc_html__()`, `esc_attr__()`) for security
+
+### Pattern 3: Variables in Translatable Strings
+**What:** Use placeholders with `sprintf()` or `printf()` for strings containing variables
+**When to use:** Any translatable string that includes dynamic content
+**Example:**
+```php
+// Source: https://developer.wordpress.org/plugins/internationalization/how-to-internationalize-your-plugin/
+
+// Correct approach with sprintf
+printf(
+    /* translators: %s: Customer name */
+    esc_html__( 'Moving list for %s', 'siegel-umzugsliste' ),
+    esc_html( $customer_name )
+);
+
+// WRONG - variables inside translation string
+// _e( "Moving list for $customer_name", 'siegel-umzugsliste' ); // Don't do this!
+
+// Multiple placeholders with numbered arguments (for reordering in translations)
+printf(
+    /* translators: 1: source address, 2: destination address */
+    esc_html__( 'Moving from %1$s to %2$s', 'siegel-umzugsliste' ),
+    esc_html( $source ),
+    esc_html( $destination )
+);
+```
+
+**Why this matters:** Translators see the literal string during extraction. If variables are embedded, translations break because the runtime string differs from the extracted string.
+
+### Pattern 4: Translating Data Array Strings
+**What:** Wrap array values in `__()` calls so they're extracted to POT and translatable
+**When to use:** Static data arrays like furniture items and room names
+**Example:**
+```php
+// Based on research: https://codex.wordpress.org/I18n_for_WordPress_Developers
+
+public static function get_rooms() {
+    return array(
+        'wohnzimmer'       => __( 'Wohnzimmer', 'siegel-umzugsliste' ),
+        'schlafzimmer'     => __( 'Schlafzimmer', 'siegel-umzugsliste' ),
+        'arbeitszimmer'    => __( 'Arbeitszimmer', 'siegel-umzugsliste' ),
+        'bad'              => __( 'Bad', 'siegel-umzugsliste' ),
+        'kueche_esszimmer' => __( 'Küche/Esszimmer', 'siegel-umzugsliste' ),
+        'kinderzimmer'     => __( 'Kinderzimmer', 'siegel-umzugsliste' ),
+        'keller'           => __( 'Keller/Speicher/Garage', 'siegel-umzugsliste' ),
+    );
+}
+
+// For nested arrays (furniture items)
+array(
+    'name' => __( 'Sofa, Couch, je Sitz', 'siegel-umzugsliste' ),
+    'cbm' => 0.4,
+    'montage' => true
+),
+```
+
+**Important:** For email generation that must always be in German, you'll need a separate mechanism to get original German strings (see Pattern 6).
+
+### Pattern 5: Locale Switching for Email Generation
+**What:** Temporarily switch to German locale when generating email, then restore
+**When to use:** Email generation that must always be in German regardless of site locale
+**Example:**
+```php
+// Source: https://developer.wordpress.org/reference/functions/switch_to_locale/
+// Known issue: https://core.trac.wordpress.org/ticket/39210
+
+public static function generate_email_in_german( $data ) {
+    // Switch to German
+    switch_to_locale( 'de_DE' );
+
+    // Generate email using translated strings
+    // All __() calls will now return German translations
+    $email_html = self::generate( $data );
+
+    // Restore previous locale
+    restore_previous_locale();
+
+    return $email_html;
+}
+```
+
+**Critical caveat:** `switch_to_locale()` has a known bug where plugin translations don't automatically reload. See "Don't Hand-Roll" section for the required workaround.
+
+### Pattern 6: Accessing Original Strings for Email
+**What:** Maintain separate German string lookup to bypass translation system for email
+**When to use:** When you need original German strings regardless of translation state
+**Example:**
+```php
+// Alternative to locale switching if it proves problematic
+
+/**
+ * Get untranslated German furniture data for email
+ * Returns furniture items with original German names
+ */
+public static function get_furniture_items_german( $room_key ) {
+    // Same structure as get_all_furniture_data() but without __() calls
+    $german_data = array(
+        'wohnzimmer' => array(
+            array( 'name' => 'Sofa, Couch, je Sitz', 'cbm' => 0.4, 'montage' => true ),
+            // ... rest of items with hardcoded German strings
+        ),
+    );
+
+    return $german_data[ $room_key ] ?? array();
+}
+```
+
+**Tradeoff:** Duplicates data but guarantees German email regardless of translation state. Decision: Use locale switching first, fall back to this if issues arise.
+
+### Pattern 7: POT File Generation
+**What:** Generate POT template file that contains all translatable strings
+**When to use:** During development after adding/changing translatable strings, before release
+**Example:**
+```bash
+# Source: https://developer.wordpress.org/cli/commands/i18n/make-pot/
+
+# Navigate to plugin root
+cd /path/to/wp-content/plugins/siegel-umzugsliste
+
+# Generate POT file
+wp i18n make-pot . languages/siegel-umzugsliste.pot --domain=siegel-umzugsliste
+
+# Initialize German PO file from POT (first time only)
+msginit --input=languages/siegel-umzugsliste.pot \
+        --locale=de_DE \
+        --output-file=languages/siegel-umzugsliste-de_DE.po
+
+# After editing PO file, compile to MO
+msgfmt languages/siegel-umzugsliste-de_DE.po \
+       -o languages/siegel-umzugsliste-de_DE.mo
+```
+
+### Anti-Patterns to Avoid
+- **Variables in gettext calls:** Never use `__( "Text $variable", 'domain' )` - breaks translation extraction
+- **Concatenating translations:** Don't split sentences across multiple `__()` calls - breaks grammar in other languages
+- **Dynamic text domains:** Never use `__( 'Text', $variable_domain )` - must be string literal
+- **Forgetting text domain:** Omitting the second parameter breaks translations
+- **Wrong escaping context:** Using `esc_html__()` for attributes or vice versa - security risk
+- **Text domain in variable:** `__( 'Text', DOMAIN_CONSTANT )` won't work - must be literal string
+
+## Don't Hand-Roll
+
+Problems that look simple but have existing solutions:
+
+| Problem | Don't Build | Use Instead | Why |
+|---------|-------------|-------------|-----|
+| POT file extraction | Custom regex/parser to find strings | `wp i18n make-pot` | Handles PHP, JS, edge cases, comments, context, plurals. Regex misses nested calls, string concatenation, heredoc. |
+| PO to MO compilation | Custom binary MO writer | `msgfmt` from gettext tools | MO format is complex binary with endianness, hash tables, offsets. Msgfmt is battle-tested. |
+| Locale switching with plugin translations | Just use `switch_to_locale()` alone | Add `change_locale` hook to reload text domain | Core bug (#39210): plugin translations unload on locale switch. Hook workaround required. |
+| Fallback to German for unsupported locales | Custom `gettext` filter to check locale | Language Fallback plugin OR custom `locale` filter | German fallback needs to apply before translation loading, not during gettext calls. Requires locale chain modification. |
+| JavaScript translation | Custom JSON translation loader | `wp_localize_script()` for simple cases, `wp_set_script_translations()` for Gutenberg | WordPress has built-in mechanisms. Custom loaders miss WordPress hooks, filters, caching. |
+| Translation file discovery | Custom file scanner | Loco Translate plugin | Handles .pot/.po/.mo scanning, fuzzy matching, MO compilation, editor UI. Complex directory structures. |
+
+**Key insight:** WordPress i18n has sharp edges (locale switching bug, text domain literal requirement, MO binary format). The ecosystem has mature tools that handle these. Custom solutions inevitably rediscover the same bugs.
+
+## Common Pitfalls
+
+### Pitfall 1: Text Domain Doesn't Match Plugin Slug
+**What goes wrong:** Translations don't load, WordPress.org translation system doesn't work, Loco Translate can't auto-discover
+**Why it happens:** Developer chooses descriptive text domain without realizing it must match folder name
+**How to avoid:** Text domain must match plugin folder name, use dashes (not underscores), lowercase only
+**Warning signs:** `load_plugin_textdomain()` returns false, translations exist but don't apply, Loco Translate doesn't find the plugin
+**Current issue:** This plugin has `Text Domain: umzugsliste` in header but folder is `Siegel-Umzugsliste`. Correct text domain should be `siegel-umzugsliste`.
+
+### Pitfall 2: switch_to_locale() Doesn't Load Plugin Translations
+**What goes wrong:** After calling `switch_to_locale('de_DE')`, plugin strings still show in original locale instead of German
+**Why it happens:** WordPress core bug #39210 - `switch_to_locale()` unloads all text domains and reloads core translations, but plugin text domains aren't automatically reloaded
+**How to avoid:** Hook into `change_locale` action and manually call `load_plugin_textdomain()` to reload plugin translations
+**Warning signs:** Core WordPress strings change language but plugin strings don't, translations work on normal pages but not after `switch_to_locale()`
+**Solution:**
+```php
+// Workaround for switch_to_locale() plugin translation bug
+add_action( 'change_locale', function( $locale ) {
+    // Reload plugin text domain after locale change
+    unload_textdomain( 'siegel-umzugsliste' );
+    load_plugin_textdomain(
+        'siegel-umzugsliste',
+        false,
+        dirname( plugin_basename( __FILE__ ) ) . '/languages'
+    );
+} );
+```
+
+### Pitfall 3: Variables Inside Translation Strings
+**What goes wrong:** Translations don't work - string with variable content never matches extracted POT string
+**Why it happens:** POT extraction sees literal code, but runtime sees different string after variable interpolation
+**How to avoid:** Always use `sprintf()` or `printf()` with placeholders, never embed variables directly
+**Warning signs:** Translation exists in PO file but doesn't apply, POT file contains partial string without variable content
+**Example:**
+```php
+// WRONG - variable interpolation
+$msg = __( "Hello $name", 'siegel-umzugsliste' );
+
+// CORRECT - sprintf with placeholder
+$msg = sprintf( __( 'Hello %s', 'siegel-umzugsliste' ), $name );
+```
+
+### Pitfall 4: Forgetting to Regenerate POT After Code Changes
+**What goes wrong:** New strings don't appear in Loco Translate, translators can't translate new features, translations fall back to English
+**Why it happens:** POT file is static - it's a snapshot of translatable strings at generation time
+**How to avoid:** Regenerate POT file before each release, add to release checklist, consider adding to CI/CD
+**Warning signs:** Recent code changes have translatable strings but they don't appear in translation editor
+**Solution:** Always run `wp i18n make-pot` before committing translation-related changes
+
+### Pitfall 5: Wrong Escaping Function for Context
+**What goes wrong:** XSS vulnerabilities or broken HTML entity display
+**Why it happens:** `esc_html__()` encodes quotes differently than `esc_attr__()`, using wrong one breaks output
+**How to avoid:** Use `esc_html__()` for HTML content, `esc_attr__()` for HTML attributes, `esc_js__()` for JavaScript strings
+**Warning signs:** Quote marks display as `&quot;` in visible text, or HTML attributes break with special characters
+**Example:**
+```php
+// CORRECT - html escaping for content
+echo '<p>' . esc_html__( 'Room: "Living Room"', 'siegel-umzugsliste' ) . '</p>';
+// Output: <p>Room: "Living Room"</p>
+
+// CORRECT - attribute escaping for attributes
+echo '<input placeholder="' . esc_attr__( 'Enter name', 'siegel-umzugsliste' ) . '">';
+
+// WRONG - html escaping in attribute breaks quotes
+// echo '<input placeholder="' . esc_html__( 'Enter name', 'siegel-umzugsliste' ) . '">';
+```
+
+### Pitfall 6: Translation Arrays Not Extracted to POT
+**What goes wrong:** Array-based strings (like furniture items) don't appear in POT file for translation
+**Why it happens:** If arrays use plain strings without `__()` calls, WP-CLI doesn't recognize them as translatable
+**How to avoid:** Wrap every translatable string in arrays with `__()`, even if it looks redundant
+**Warning signs:** Form displays furniture items but they don't appear in Loco Translate
+**Solution:**
+```php
+// WRONG - plain strings in array
+return array(
+    'wohnzimmer' => 'Wohnzimmer',
+    'schlafzimmer' => 'Schlafzimmer',
+);
+
+// CORRECT - wrapped in __()
+return array(
+    'wohnzimmer' => __( 'Wohnzimmer', 'siegel-umzugsliste' ),
+    'schlafzimmer' => __( 'Schlafzimmer', 'siegel-umzugsliste' ),
+);
+```

+
+## State of the Art
+
+| Old Approach | Current Approach | When Changed | Impact |
+|--------------|------------------|--------------|--------|
+| Manual `load_plugin_textdomain()` required | Optional for WP.org plugins (4.6+) | WordPress 4.6 (2016) | WP.org plugins auto-load from translate.wordpress.org, but manual loading still needed for local files and Loco Translate |
+| `xgettext` for POT extraction | `wp i18n make-pot` WP-CLI command | WP-CLI 2.1.0 (2019) | WordPress-aware extraction, handles edge cases, JS support, simpler workflow |
+| Email always in site locale | `switch_to_locale()` for per-user language | WordPress 4.7 (2016) | Can send emails in recipient's language, but has plugin translation bug (#39210) requiring workaround |
+| Manual JSON file generation for JS | `wp_set_script_translations()` auto-generates | WordPress 5.0 (2018) | Gutenberg blocks can use same POT file, automatic JSON extraction from PO files |
+| Separate fallback locale logic | Native fallback chains proposed | Ticket #28197 (proposed, not in core) | Still requires Language Fallback plugin for locale family fallback (es_MX → es_ES) |
+
+**Deprecated/outdated:**
+- **`pomo` library direct usage:** WordPress core abstracts this, use `load_plugin_textdomain()` instead
+- **`makepot.php` script:** Replaced by WP-CLI `wp i18n make-pot`, more reliable and maintained
+- **Domain Path without leading slash:** Modern convention is `/languages`, old plugins used `languages` (no slash) - both work but `/languages` is standard
+- **`languages_loaded` action for text domain loading:** Use `init` hook instead, `languages_loaded` was never officially documented
+
+## Open Questions
+
+Things that couldn't be fully resolved:
+
+1. **German fallback for unsupported locales**
+   - What we know: WordPress doesn't natively fall back to de_DE for non-German, non-English locales (e.g., fr_FR with no French translation would show English, not German)
+   - What's unclear: Whether this is important enough to warrant the Language Fallback plugin, or if just shipping de_DE and en_US translations is sufficient
+   - Recommendation: Start without Language Fallback plugin. If a site uses a locale other than de_DE or en_US and lacks that translation, it will fall back to English (the strings in code). Only add Language Fallback if users actually need de_DE as ultimate fallback instead of English. Decision marked for Claude's discretion in CONTEXT.md.
+
+2. **Locale switching vs. separate German data**
+   - What we know: `switch_to_locale()` works but requires `change_locale` hook workaround, separate German data array avoids translation system entirely
+   - What's unclear: Which approach is more maintainable long-term and less fragile
+   - Recommendation: Implement `switch_to_locale()` with the `change_locale` workaround first (standard WordPress pattern). If it proves problematic during testing, fall back to separate German data array. Locale switching is more "WordPress-native" and keeps data in one place.
+
+3. **JavaScript localization scope**
+   - What we know: Frontend validation uses JavaScript and shows error messages
+   - What's unclear: Whether current JS validation messages are inline in HTML (easy to translate via PHP) or in separate JS files (requires `wp_localize_script()` or `wp_set_script_translations()`)
+   - Recommendation: Inspect existing JS validation implementation. If messages are in separate JS file, use `wp_localize_script()` to pass translated strings from PHP. If messages are inline in PHP-rendered HTML, wrap them in `esc_js( __() )`.
+
+4. **POT file freshness in version control**
+   - What we know: POT should be regenerated before each release, but committing it to git means it can go stale between releases
+   - What's unclear: Whether to commit POT file to git or generate it only for releases
+   - Recommendation: Commit POT file to git for Loco Translate compatibility on development installs, and add "regenerate POT" step to release checklist. Alternative: Use git hooks to auto-regenerate on commit, but that adds complexity.

+## Metadata
+
+**Confidence breakdown:**
+- Standard stack: HIGH - WordPress i18n API is stable and well-documented since WP 2.1, gettext is industry standard
+- Architecture: HIGH - Official handbook provides clear patterns, WP-CLI and Loco Translate are de facto standards
+- Pitfalls: HIGH - Known issues like #39210 are documented in Trac, text domain matching is enforced by WP.org, variable interpolation bugs are common and well-known
+- Email locale switching: MEDIUM - Pattern is documented but workaround required due to core bug, needs testing to confirm effectiveness
+- German fallback: LOW - Language Fallback plugin exists but unclear if needed for this use case
+
+**Research date:** 2026-02-06
+**Valid until:** 2026-03-08 (30 days - WordPress i18n is stable, patterns unlikely to change rapidly)
+
+**Critical action items for planning:**
+1. Change text domain from `umzugsliste` to `siegel-umzugsliste` throughout codebase
+2. Implement `change_locale` hook workaround for `switch_to_locale()` bug
+3. Decide: locale switching vs. separate German data for email generation (recommend trying locale switching first)
+4. Decide: ship German PO/MO files or only POT template (recommend shipping both for out-of-box German support)

+
+### Requirements Coverage
+
+| Requirement | Status | Blocking Issue |
+|-------------|--------|----------------|
+| REQ-7 (i18n support) | ⚠️ PARTIAL | wp_die error message gap prevents complete i18n coverage |
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| includes/class-form-handler.php | 120-127 | Hardcoded German strings in wp_die message | 🛑 Blocker | Error page cannot be translated; shows German to all users regardless of site locale |
+
+**Details:**
+```php
+// Lines 120-127: NOT WRAPPED IN GETTEXT
+wp_die(
+    '<h1>E-Mail konnte nicht versendet werden</h1>
+    <p>Ihre Anfrage wurde gespeichert, aber die E-Mail konnte nicht versendet werden.</p>
+    <p><strong>Bitte kontaktieren Sie uns telefonisch:</strong></p>
+    <p>Wiesbaden: <a href="tel:+4961122020">(06 11) 2 20 20</a><br>
+    Mainz: <a href="tel:+49613122141">(0 61 31) 22 21 41</a></p>
+    <p><a href="' . home_url() . '">Zurück zur Startseite</a></p>',
+    'E-Mail-Fehler'
+);
+```
+
+**Impact:** Email failure error page always displays in German, even if site is set to English or another language. This is inconsistent with the rest of the form UI which respects site locale.
+
+**Expected:** Should be wrapped with esc_html__() and concatenated, similar to pattern in Plan 02 specification (lines 202-212 of 09-02-PLAN.md).
+
+### Human Verification Required
+
+None programmatically required, but recommended manual testing:
+
+1. **Test German locale display**
+   - Set WordPress site locale to de_DE
+   - View form at shortcode page
+   - Expected: All UI shows German (Umzugsliste, Beladeadresse, Anfrage absenden, etc.)
+   - Why human: Visual verification of complete German display
+
+2. **Test English locale display**
+   - Set WordPress site locale to en_US
+   - View form at shortcode page
+   - Expected: All UI shows English (Moving List, Loading Address, Submit Request, etc.) EXCEPT error page if email fails
+   - Why human: Visual verification of complete English display
+
+3. **Test email locale forcing**
+   - Set site locale to en_US
+   - Submit form successfully
+   - Check email received
+   - Expected: Email content is in German (Voraussichtlicher Umzugstermin, Beladeadresse, Wohnzimmer labels, etc.)
+   - Why human: Email content inspection requires real submission and email delivery
+
+4. **Test JavaScript validation translations**
+   - Set site locale to de_DE, then en_US
+   - Trigger client-side validation (submit without required fields)
+   - Expected: Validation messages match site locale
+   - Why human: Client-side behavior testing
+
+### Gaps Summary
+
+**1 gap found blocking full i18n implementation:**
+
+The wp_die error message displayed when email sending fails (lines 120-127 in `includes/class-form-handler.php`) contains 5 hardcoded German strings:
+- "E-Mail konnte nicht versendet werden" (page title)
+- "Ihre Anfrage wurde gespeichert, aber die E-Mail konnte nicht versendet werden." (message)
+- "Bitte kontaktieren Sie uns telefonisch:" (call to action)
+- "Zurück zur Startseite" (link text)
+- "E-Mail-Fehler" (wp_die title parameter)
+
+**Why this matters:** This is a user-facing error page that appears when a critical failure occurs. All other form UI respects the site locale, but this error page always shows German regardless of locale setting. This creates an inconsistent user experience and prevents the plugin from being fully internationalized.
+
+**What needs to be fixed:** Wrap all 5 strings in appropriate gettext functions (esc_html__(), esc_html_e()) with the 'siegel-umzugsliste' text domain, add English translations to the message catalog, and provide German translations in the .po file.
+
+**Effort:** Small — single function call, 5 strings to wrap, regenerate POT/PO/MO files.
+
+---
+
+## Verification Methodology
+
+**Level 1 (Existence):** All 13 required artifacts exist and are non-empty.
+
+**Level 2 (Substantive):** 
+- All PHP files pass syntax check (`php -l`)
+- Text domain is literal string 'siegel-umzugsliste' throughout (never variable)
+- 242+ gettext calls across all files (13 CPT + 6 admin menu + 20+ settings + 3 date + 163 furniture + 43 form renderer + ~14 form handler)
+- POT file has 224 extractable msgid entries
+- PO file has 222 translated msgstr entries (only metadata empty)
+- MO file is 14KB compiled binary
+
+**Level 3 (Wired):**
+- load_plugin_textdomain() called on init action (priority 1)
+- change_locale hook registered with unload/reload
+- wp_localize_script() passes translated strings to JavaScript
+- form.js references umzugslisteL10n global
+- switch_to_locale('de_DE') wraps email generation
+- restore_previous_locale() restores after email sent
+- All furniture/room data consumed by form renderer
+- Email generator called within locale switch context
+
+**Anti-pattern scan:** 1 blocker found (wp_die hardcoded German)
+
+**Import/usage verification:** All classes properly wired and called

+
+## Cross-Phase Integration
+
+### Verified Connections
+
+- Phase 1 → All: Plugin bootstrap, CPT, constants properly consumed
+- Phase 2 → Phase 4: `get_rooms()` and `get_furniture_items()` used in form renderer
+- Phase 2 → Phase 5: CBM values passed via data attributes, JS reads correctly
+- Phase 2 → Phase 6: Email generator uses furniture data to build HTML tables
+- Phase 3 → Phase 6: Receiver email and thank you URL used in form handler
+- Phase 3 → Phase 7: Captcha provider and keys used for widget/verification
+- Phase 4 → Phase 5: Data attributes and DOM structure consumed by JS calculations
+- Phase 4 → Phase 6: Field names match expected POST format in form handler
+- Phase 4 → Phase 7: Error display and captcha widget integrated in form
+- Phase 6 → Phase 1: CPT entries created with proper meta data
+- Phase 7 → Phase 6: Captcha verification runs before form processing
+
+### Integration Score: 8/10
+
+## E2E Flow Verification
+
+### Flow 1: Happy Path (Form → Email → Redirect)
+**Status: COMPLETE**
+Load form → fill data → real-time calculations → submit → nonce check → captcha check → validation → sanitize → save CPT → generate email → send via wp_mail → redirect to thank you page
+
+### Flow 2: Validation Error Path
+**Status: COMPLETE (with session bug)**
+Submit invalid → client validation blocks OR server validation catches → error transient → redirect back → display errors inline
+**Bug:** `session_id()` used without `session_start()` — transient key may be empty
+
+### Flow 3: Admin View Submissions
+**Status: COMPLETE**
+Navigate to Umzugsliste → Eintraege → view CPT list → click entry → see JSON data and meta
+
+**Flows Score: 3/3 flows functional**
+
+## Critical Gaps
+
+### 1. i18n Not Implemented (Requirement 7)
+- No `__()` or `_e()` gettext function calls anywhere
+- No `.pot`, `.po`, or `.mo` translation files
+- No `languages/` directory
+- Text domain declared but never loaded (`load_plugin_textdomain()` missing)
+- All user-facing strings hardcoded in German
+- **Decision needed:** Is English support required for v1.0?
+
+### 2. Session ID Bug
+- `session_id()` returns empty string when PHP session not started
+- Used in form-handler.php (lines 72, 82) and form-renderer.php (line 49)
+- Transient key degrades to `umzugsliste_errors_default`
+- In multi-user scenarios, errors could cross-contaminate between users
+- **Fix required before production**
+
+### 3. Additional Work Sections Orphaned
+- Phase 2 extracted 32 fields across 6 sections (Montage, Schrank, Elektriker, Dubelarbeiten, Packarbeiten, Anfahrt)
+- `get_additional_work()` method exists but is never called
+- Not rendered in form, not included in email, not validated
+- **Decision needed:** Required for v1.0 or defer to v1.1?
+
+### 4. Sonstiges Free Text Missing
+- Legacy form had a free text "Sonstiges" section
+- Not implemented in any phase
+- **Decision needed:** Required for v1.0 or defer?
+
+## Tech Debt
+
+| Phase | Item | Priority |
+|-------|------|----------|
+| 06 | session_id() without session_start() | Critical |
+| 02 | get_additional_work() orphaned | High |
+| 06 | No admin resend email | Low |
+| 06 | No email queue/retry | Low |
+| 07 | reCAPTCHA v3 no non-JS fallback | Low |
+| 07 | Simple email regex validation | Low |
+
+## Security Verification
+
+- Nonce protection: IMPLEMENTED
+- Data sanitization: IMPLEMENTED
+- SQL injection protection: SAFE (WordPress APIs)
+- XSS protection: IMPLEMENTED (esc_html, esc_attr)
+- CSRF protection: IMPLEMENTED (nonce + referer check)
+
+## Recommendations
+
+### Before Completing Milestone
+1. **Decide on i18n:** Accept German-only for v1.0 or implement before shipping
+2. **Fix session bug:** Replace `session_id()` with reliable alternative
+3. **Decide on additional work sections:** Ship without or implement
+
+### For Next Milestone
+- i18n with full English translation (if deferred)
+- Additional work sections integration
