Consolidate documentation, bump to v1.2.1

Condense CLAUDE.md from ~1960 to ~160 lines keeping only essential architecture and lessons learned. Merge INSTALL.md into README.md and IMPLEMENTATION.md into CLAUDE.md, then delete the source files. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Update .gitignore: add logs/ dir and compiled .mo files

@@ -5,6 +5,395 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 ## [1.2.1] - 2026-03-01
 ### Changed
 - Consolidated documentation: merged INSTALL.md into README.md, merged IMPLEMENTATION.md into CLAUDE.md
 - Condensed CLAUDE.md from ~1960 lines to ~160 lines, keeping only essential architecture and lessons learned
 - README.md now includes full installation guide, usage tutorial, and troubleshooting section
 - Cleaned up .gitignore
 ### Removed
 - INSTALL.md (content merged into README.md)
 - IMPLEMENTATION.md (content merged into CLAUDE.md)
 ## [1.2.0] - 2026-03-01
 ### Fixed
 - **CRITICAL**: Product selection always empty regardless of configuration (categories, tags, or SKUs)
  - Root cause: Product query used a `meta_query` checking `_product_type` in `wp_postmeta`, but WooCommerce stores product types in the `product_type` **taxonomy** — the `!=` comparison with a non-existent meta key caused an INNER JOIN returning zero results
  - Fix: Replaced broken `meta_query` with correct `tax_query` using `product_type` taxonomy to exclude composable products
 - **CRITICAL**: Cart price always 0.00 despite correct frontend price calculation
  - Root cause: `composable_price_calculated` flag was persisted to the cart session, preventing price recalculation on subsequent page loads — but `set_price()` only modifies the in-memory product object and is lost between requests
  - Fix: Removed per-item session flag; the existing static `$already_calculated` flag already prevents duplicate calculation within a single request
 - **Admin tab rendering**: Both General and Composable Options panels visible on initial page load
  - Root cause: JavaScript manually showed `#composable_product_data` via `.show()` without hiding the General panel
  - Fix: Trigger WooCommerce's native tab click instead, so the tab system handles panel visibility correctly
 ### Added
 - **Gitea CI/CD release workflow** (`.gitea/workflows/release.yml`)
  - Triggered on `v*` tags
  - Installs PHP 8.3 with production Composer dependencies
  - Compiles `.po` → `.mo` translations
  - Verifies plugin version matches tag
  - Builds release ZIP with proper WordPress directory structure
  - Generates SHA-256 checksums
  - Verifies package contains main plugin file and vendor directory
  - Extracts changelog for release notes
  - Creates Gitea release with attachments via API
 ### Removed
 - Debug logging from v1.1.14 (no longer needed after root cause identified)
 ### Technical
 - Modified files: includes/Product_Type.php, includes/Cart_Handler.php, assets/js/admin.js
 - New file: .gitea/workflows/release.yml
 - Product query now correctly uses `tax_query` with `product_type` taxonomy (`NOT IN` operator)
 - Cart price recalculated on every request via `woocommerce_before_calculate_totals` hook
 - Admin JS uses `$('ul.product_data_tabs li.composable_options a').trigger('click')` for native WooCommerce tab handling
 ## [1.1.14] - 2025-12-31
 ### Added
 - **DEBUG**: Comprehensive debug logging to troubleshoot product retrieval issues
 - Error log output shows selection criteria, query arguments, and results
 - Logs each product/variation being added to help identify filtering issues
 - Enable by setting WP_DEBUG to true in wp-config.php
 ### Technical
 - Modified file: includes/Product_Type.php (added error_log statements throughout get_available_products())
 - Logs criteria array (categories, tags, SKUs)
 - Logs WP_Query arguments before execution
 - Logs number of posts found by query
 - Logs each variable product's variation count
 - Logs each variation/simple product being added with name
 - Logs total products available at end
 - All logging wrapped in WP_DEBUG checks (no performance impact in production)
 ### Notes
 - This is a debug release to help diagnose why products aren't showing
 - No functional changes from v1.1.13
 - User should enable WP_DEBUG and check debug.log or error.log
 - Log output will show exactly where products are being filtered out
 - All translation files remain at 100% completion (57/57 strings)
 ## [1.1.13] - 2025-12-31
 ### Fixed
 - **CRITICAL**: "No products available for selection" message showing even when products are configured
 - Removed overly strict `is_in_stock()` requirement that was filtering out all products
 - Products now show regardless of stock status (out-of-stock items are displayed but disabled)
 - Added `'relation' => 'AND'` to meta_query for proper handling of multiple meta conditions
 ### Changed
 - Product retrieval now shows all purchasable products, not just in-stock ones
 - Stock status still displayed on frontend with appropriate styling
 - Out-of-stock items shown but disabled via checkbox and visual indicators
 - Frontend stock management from v1.1.0 still fully functional
 ### Technical
 - Modified file: includes/Product_Type.php (lines 117-124, 177, 181)
 - Changed from `$variation->is_in_stock() && $variation->is_purchasable()` to just `$variation->is_purchasable()`
 - Changed from `$product->is_in_stock() && $product->is_purchasable()` to just `$product->is_purchasable()`
 - Added `'relation' => 'AND'` to meta_query array for WordPress query compatibility
 ### Notes
 - This fixes the issue where NO products were showing in the selector
 - Stock validation still occurs at add-to-cart time (Stock_Manager class)
 - Frontend still displays stock badges (in stock, low stock, out of stock)
 - Out-of-stock items remain non-selectable via disabled checkboxes
 - All translation files remain at 100% completion (57/57 strings)
 ## [1.1.12] - 2025-12-31
 ### Fixed
 - **CRITICAL**: Variable product variations still not appearing in product selector after v1.1.11 release
 - Changed variation retrieval method from `get_available_variations()` to `get_children()` for more reliable variation ID retrieval
 - `get_available_variations()` returns complex data arrays which may not work in all contexts
 - `get_children()` returns simple array of variation IDs directly, ensuring consistent results
 ### Technical
 - Modified file: includes/Product_Type.php (lines 171-184)
 - Changed from `$product->get_available_variations()` to `$product->get_children()`
 - More direct and reliable method for retrieving variation IDs
 - Each variation ID passed to `wc_get_product()` for full product object
 - Maintains all stock and purchasability checks from v1.1.11
 ### Notes
 - This is a patch release fixing the variable product support introduced in v1.1.11
 - User reported "nope, still no product selectable" after v1.1.11
 - Root cause: `get_available_variations()` returns variation data arrays instead of clean IDs
 - `get_children()` is the standard WooCommerce method for retrieving variation IDs
 - All translation files remain at 100% completion (57/57 strings - no changes needed)
 ## [1.1.11] - 2025-12-31
 ### Added
 - **FEATURE**: Variable product support - composable products can now include variable products and their variations
 - Variable products automatically expand to show all available variations as selectable items
 - Each variation displays with full attribute information (e.g., "Product - Color: Red, Size: Large")
 ### Fixed
 - Products not showing in selector when all available products were variable products
 - Variable products were being filtered out because parent products aren't directly purchasable
 ### Changed
 - Modified `get_available_products()` to detect and handle variable products
 - Variable products now expand into their individual variations
 - Each variation checked individually for stock status and purchasability
 - Simple products continue to work exactly as before
 ### Technical
 - Modified file: includes/Product_Type.php (lines 160-188)
 - Added logic to detect `is_type('variable')` products
 - Uses `get_available_variations()` to retrieve all variations
 - Each variation validated with `is_in_stock()` and `is_purchasable()`
 - Maintains backward compatibility with simple products
 ### Notes
 - This is a feature enhancement release, not a bug fix
 - Resolves the issue where categories containing only variable products showed no selections
 - Variations display with their parent product name plus selected attributes
 - Stock management works correctly for both simple products and variations
 - All translation files remain at 100% completion (57/57 strings - no new strings added)
 ## [1.1.10] - 2025-12-31
 ### Fixed
 - **CRITICAL**: Admin panel - Both General and Composable tabs visible simultaneously on initial page load
 - **CRITICAL**: Frontend - No products showing in product selector, only cart button and pricing visible
 - Empty product grid now shows helpful message instead of blank space
 ### Changed
 - Added explicit `display: none` to `#composable_product_data` panel for proper initial hiding
 - Panel now only shows when `body.product-type-composable` class is present
 - Added empty state message in product selector template when no products are configured
 - Cleared Twig cache to ensure template changes take effect
 ### Added
 - Empty state message: "No products available for selection. Please configure the product criteria in the admin panel."
 - Translations for empty state message in all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH)
 - Recompiled .mo translation files
 ### Technical
 - Modified files: assets/css/admin.css (lines 7-16), templates/product-selector.twig (lines 12-15)
 - Root cause (admin): Panel lacked explicit CSS hiding rule, relied only on `hidden` class
 - Root cause (frontend): No feedback when products array is empty
 - Solution: CSS specificity + empty state conditional in Twig template
 ### Notes
 - This release fixes two critical bugs discovered immediately after v1.1.9
 - Admin interface now correctly hides composable panel until product type is selected
 - Frontend provides clear user feedback when product selection is unavailable
 - All translation files now 100% complete (57/57 strings)
 ## [1.1.9] - 2025-12-31
 ### Fixed
 - **CRITICAL**: Admin rendering completely broken - tabs disappeared and fields appeared out of context after v1.1.8 release
 - CSS selectors were too broad, hiding tab navigation along with field groups
 - Removed `!important` flags that caused overly aggressive hiding
 ### Changed
 - Made CSS selectors more specific: `.options_group.show_if_composable` for field groups only
 - Added separate rule for tab links: `.product_data_tabs li.composable_options`
 - Tab navigation now works correctly without hiding itself
 ### Technical
 - Modified files: assets/css/admin.css (lines 22-40)
 - Root cause: `.show_if_composable` class used by WooCommerce for both tab links AND field groups
 - Solution: Separate selectors for each use case to prevent unintended hiding
 ### Notes
 - This release fixes critical regression introduced in v1.1.8
 - Admin interface now renders correctly with visible tabs and properly positioned fields
 - No `!important` flags needed with specific selectors
 ## [1.1.8] - 2025-12-31
 ### Fixed
 - **CRITICAL**: Admin rendering bug where both General and Composable Options tabs showed simultaneously on initial page load
 - **CRITICAL**: Frontend product selector not appearing on product pages - WooCommerce's default add-to-cart button now hidden for composable products
 - **CRITICAL**: Price formatting not localized - prices now display with proper currency symbols, decimal separators, and thousand separators for all locales
 ### Added
 - `wc_price()` Twig function for proper price formatting in templates
 - `formatPrice()` JavaScript method with full WooCommerce locale support
 - Price format localization data passed to frontend JavaScript (decimal/thousand separators, currency position, number of decimals)
 - `hide_default_add_to_cart()` method to prevent WooCommerce's default purchase UI for composable products
 ### Changed
 - Enhanced CSS specificity with `!important` flags for proper tab visibility control
 - Template now uses `{{ fixed_price_html|raw }}` instead of raw currency concatenation
 - Product selector passes pre-formatted price HTML from `wc_price()` function
 - Frontend JavaScript updates prices dynamically using WooCommerce format settings
 ### Technical
 - Modified files: assets/css/admin.css (+24 lines), includes/Cart_Handler.php (+14 lines), includes/Plugin.php (+7 lines), includes/Product_Selector.php (+2 lines), templates/product-selector.twig, assets/js/frontend.js (+28 lines)
 - All PHP files pass syntax validation
 - Supports Swiss format (CHF 50.-), European format (50,00 €), US format ($50.00), and all other WooCommerce locales
 - Thousand separator support: comma (1,000), dot (1.000), apostrophe (1'000), space (1 000)
 ### Notes
 - This release fixes all three critical UI bugs reported in CLAUDE.md
 - Admin tabs now display correctly on initial page load without JavaScript flicker
 - Frontend product selector is now the only purchase interface (no WooCommerce default button)
 - All prices maintain proper locale formatting during dynamic updates
 ## [1.1.7] - 2025-12-31
 ### Added
 - Compiled .mo translation files for all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH)
 - WordPress can now load translations in admin and frontend areas
 ### Fixed
 - **CRITICAL**: Missing translations in WordPress admin when using non-English locales
 - Settings page ("Composable Products", "Default Selection Limit", etc.) now properly translated
 - Product settings ("Composable Options", "Selection Criteria", etc.) now properly translated
 ### Technical
 - Compiled .mo files from .po sources using msgfmt
 - All 6 locales now have complete translation coverage (56/56 strings translated and compiled)
 - .mo files required for WordPress i18n system to display translations
 ### Notes
 - Previous versions included .po translation files but WordPress requires compiled .mo files
 - This release makes all existing translations actually visible to users
 ## [1.1.6] - 2025-12-31
 ### Added
 - Complete translations for all admin area strings across all 6 supported locales
 - "Fixed Price" field label and description translations
 ### Changed
 - Updated translation template (.pot) to version 1.1.6
 - Simplified "How to calculate the price" description text
 ### Technical
 - All .po files now include translations for v1.1.4 admin strings
 - 100% translation coverage maintained across all locales (56/56 strings)
 - German formal/informal variants properly differentiated (Sie vs. du)
 ## [1.1.5] - 2025-12-31
 ### Fixed
 - **CRITICAL**: Fixed Twig template error "Unknown 'esc_attr' filter" when rendering product selector
 - Template compatibility issue when other plugins (e.g., WooCommerce Tier and Package Prices) use Twig
 - WordPress escaping functions now properly registered as both Twig functions AND filters
 ### Technical
 - Added `TwigFilter` registrations for `esc_html`, `esc_attr`, and `esc_url` in `Plugin::init_twig()`
 - Template can now use both syntax styles: `{{ value|esc_attr }}` (filter) and `{{ esc_attr(value) }}` (function)
 - Prevents conflicts when multiple plugins bundle their own Twig installations
 ### Notes
 - Previous versions only registered escaping functions as Twig functions, not filters
 - Template used filter syntax (`|esc_attr`) which failed when parsed by external Twig instances
 - Fix ensures compatibility regardless of which Twig instance processes the template
 ## [1.1.4] - 2025-12-31
 ### Added
 - Fixed price field in Composable Options tab for easier price configuration
 - JavaScript toggle to show/hide fixed price field based on selected pricing mode
 ### Changed
 - Simplified pricing mode description text in admin interface
 - Fixed price field now appears dynamically when "Fixed" pricing mode is selected
 ### Technical
 - Added `_regular_price` field with `composable_fixed_price_field` CSS class in `Product_Data.php`
 - Implemented `toggleFixedPriceField()` JavaScript function in `assets/js/admin.js`
 - Progressive disclosure pattern improves admin UX by showing relevant fields only
 ## [1.1.3] - 2024-12-31
 ### Added
 - WooCommerce HPOS (High-Performance Order Storage) compatibility declaration
 - Prevents duplicate price calculations to avoid conflicts with other pricing plugins
 ### Fixed
 - WooCommerce compatibility warnings with Analytics and other WooCommerce extensions
 - Price calculation conflicts with third-party pricing plugins
 ### Technical
 - Added `before_woocommerce_init` hook to declare HPOS compatibility
 - Implemented static flag in `Cart_Handler::calculate_cart_item_price()` to prevent multiple executions
 - Added `composable_price_calculated` flag to cart items to prevent re-calculation by other plugins
 - Ensures composable products work with WooCommerce's modern order storage system
 ## [1.1.2] - 2024-12-31
 ### Fixed
 - **CRITICAL**: Fixed persistent "Class WC_Settings_Page not found" error that continued in v1.1.1
 - Root cause: Settings.php was being included too early (during plugin init) before WC_Settings_Page was loaded
 - Solution: Delayed Settings.php inclusion until `woocommerce_get_settings_pages` filter when class is guaranteed to exist
 ### Technical
 - Removed `require_once Settings.php` from `Plugin::includes()` (line 93)
 - Added `require_once Settings.php` to `Plugin::add_settings_page()` (line 196)
 - Settings file now loads on-demand when WooCommerce requests settings pages
 - Previous hook change (woocommerce_init) was insufficient - class loading order was the real issue
 ### Notes
 - v1.1.1 attempted to fix this with hook change but the error persisted
 - This version addresses the actual root cause: premature class extension

 **Author:** Marco Graetsch
 ## Project Overview
-This plugin implements a special product type, for which users can select a limited number of product from a configurable set of simple or variable products. The limit of selectable products should be a global and per-product setting, for which global is the fallback. The set of selectable products can be defined per category, tag or SKU. The price is either a fixed price or the sum of the prices of the selected products. Think of a package of stickers as composable product, where each package can contain $limit number of stickers.
+This plugin implements a custom WooCommerce product type where customers select a limited number of products from a configurable set of simple or variable products. The limit is configurable globally and per-product. The selectable products are defined by category, tag, or SKU. Pricing is either fixed or the sum of selected products. Think of a sticker pack where each package contains N stickers chosen by the customer.

 ## Technical Stack
 - **Language:** PHP 8.3+
- **Framework:** Latest WordPress Plugin API
+- **Framework:** WordPress Plugin API
 - **E-commerce:** WooCommerce 10.0+
 - **Template Engine:** Twig 3.0 (via Composer)
 - **Frontend:** Vanilla JavaScript + jQuery
 - **Styling:** Custom CSS
- **Dependency Management:** Composer
+- **Dependencies:** Composer
- **Internationalization:** WordPress i18n (.pot/.po/.mo files)
+- **i18n:** WordPress i18n (.pot/.po/.mo), text domain: `wc-composable-product`
-
+- **CI/CD:** Gitea Actions (`.gitea/workflows/release.yml`)
 ## Implementation Details
 ### Security Best Practices
 - All user inputs are sanitized (integers for quantities/prices)
 - Nonce verification on form submissions
 - Output escaping in templates (`esc_attr`, `esc_html`, `esc_js`)
 - Direct file access prevention via `ABSPATH` check
 ### Translation Ready
 All user-facing strings use:
 ```php
 __('Text to translate', 'wc-composable-product')
 _e('Text to translate', 'wc-composable-product')
 ```
 Text domain: `wc-composable-product`
 **Translation Template:**
 - Base `.pot` file created: `languages/wc-composable-product.pot`
 - Ready for translation to any locale
 - All translatable strings properly marked with text domain
 **Available Translations:**
 - `en_US` - English (United States) [base language - .pot template]
 - `de_DE` - German (Germany, formal) ✓ Complete
 - `de_DE_informal` - German (Germany, informal "du") ✓ Complete
 - `de_CH` - German (Switzerland, formal "Sie") ✓ Complete
 - `de_CH_informal` - German (Switzerland, informal "du") ✓ Complete
 - `fr_CH` - French (Switzerland) ✓ Complete
 - `it_CH` - Italian (Switzerland) ✓ Complete
 All .po files created with 40+ translated strings. Swiss locales include CHF currency formatting in examples (e.g., "CHF 50.-").
 To compile translations to .mo files for production:
 ```bash
 for po in languages/*.po; do msgfmt -o "${po%.po}.mo" "$po"; done
 ```
 ### Create releases
 - The `vendor/` directory MUST be included in releases (Twig dependency required for runtime)
 - Running zip from wrong directory creates empty or malformed archives
 - Exclusion patterns must match the relative path structure used in zip command
 - Always verify the package with `unzip -l` and test extraction before committing
 - The `wp-core/` and `wp-plugins/` directories MUST NOT be included in releases
 - Releases are stored in `releases/` including checksums
 **Important Git Notes:**
 - Always commit from `dev` branch first
 - Tags should use format `vX.X.X` (e.g., `v1.1.22`)
 - Use annotated tags (`-a`) not lightweight tags
 - Commit messages should follow the established format with Claude Code attribution
 - `.claude/settings.local.json` changes are typically local-only (stash before rebasing)
 #### What Gets Released
 - All plugin source files
 - Compiled vendor dependencies
 - Translation files (.mo compiled from .po)
 - Assets (CSS, JS)
 - Documentation (README, CHANGELOG, etc.)
 #### What's Excluded
 - Git metadata (`.git/`)
 - Development files (`.vscode/`, `.claude/`, `CLAUDE.md`)
 - Logs and cache files
 - Previous releases
 - `composer.lock` (but `vendor/` is included)

-## Architecture Overview
+## Architecture
 ### Core Classes
-1. **Plugin.php** - Main singleton class
+1. **Plugin.php** — Main singleton class
-   - Initializes Twig template engine
+   - Initializes Twig with WordPress functions registered as both Twig functions AND filters
-   - Registers hooks and filters
+   - Registers hooks, manages asset enqueuing, provides template rendering API
-   - Manages asset enqueuing
+   - Settings.php is lazy-loaded via `woocommerce_get_settings_pages` filter (not in `includes()`) to avoid "Class WC_Settings_Page not found" errors
   - Provides template rendering API
-2. **Product_Type.php** - Custom WooCommerce product type
+2. **Product_Type.php** — Custom WooCommerce product type (`composable`)
   - Extends `WC_Product`
-   - Handles selection criteria (category/tag/SKU)
+   - Queries available products via `get_available_products()` using `WP_Query`
-   - Manages pricing modes (fixed/sum)
+   - **Critical**: Uses `tax_query` with `product_type` taxonomy to exclude composable products (NOT `meta_query` — WooCommerce stores product types as taxonomy terms)
-   - Queries available products dynamically
+   - Handles variable products by expanding them into individual variations via `get_children()`
   - Products are filtered by `is_purchasable()` only (not `is_in_stock()` — stock is shown visually and validated at add-to-cart)
-3. **Cart_Handler.php** - Cart integration
+3. **Cart_Handler.php** — Cart integration
-   - Validates product selections
+   - Validates selections, stores selected products in cart meta, calculates pricing
-   - Stores selected products in cart meta
+   - Uses `woocommerce_is_purchasable` filter to hide default add-to-cart button for composable products
-   - Calculates dynamic pricing
+   - Price recalculation uses a static `$already_calculated` flag per request (no persistent session flags — `set_price()` is in-memory only)
   - Displays selections in cart/checkout
-4. **Product_Selector.php** - Frontend renderer
+4. **Product_Selector.php** — Frontend renderer
-   - Renders Twig template with product data
+   - Renders Twig template with product data, stock info, and pre-formatted price HTML via `wc_price()`
   - Applies display settings (images/prices/total)
-5. **Admin/Product_Data.php** - Product edit interface
+5. **Admin/Product_Data.php** — Product edit interface
-   - Adds "Composable Options" tab
+   - Adds "Composable Options" tab with category/tag/SKU selection fields
-   - Category/tag/SKU selection fields
+   - Saved meta: `_composable_selection_limit`, `_composable_pricing_mode`, `_composable_criteria_type`, `_composable_categories`, `_composable_tags`, `_composable_skus`
   - Saves product metadata
-6. **Admin/Settings.php** - Global settings
+6. **Admin/Settings.php** — Global settings (extends `WC_Settings_Page`)
-   - WooCommerce settings tab integration
+   - Default selection limit, pricing mode, display preferences
   - Default limits and pricing mode
   - Display preferences
-7. **Stock_Manager.php** - Inventory management (v1.1.0+)
+7. **Stock_Manager.php** — Inventory management
-   - Stock validation for selected products
+   - Stock validation, automatic deduction on order completion, restoration on cancellation
-   - Automatic stock deduction on order completion
+   - Prevents WooCommerce double-deduction via `woocommerce_can_reduce_order_stock`
   - Stock restoration on order cancellation/refund
   - Order notes for audit trail
   - Backorder support detection
 ### Data Flow
-**Product Creation:**
+**Product Creation:** Admin selects "Composable product" type → configures criteria/limits/pricing → metadata saved as `_composable_*` fields
-1. Admin selects "Composable product" type
+**Frontend Display:** `Cart_Handler::render_product_selector()` → `Product_Type::get_available_products()` queries products via taxonomy/SKU → `Product_Selector::render()` passes data to Twig template → JavaScript handles selection UI
 2. Configures criteria, limits, pricing in product data tab
 3. Metadata saved: `_composable_*` fields
-**Frontend Display:**
+**Add to Cart:** Customer selects products → JS validates limit → AJAX request with `composable_products[]` → server-side validation (selection + stock) → selections stored in cart item data → price calculated per pricing mode
-1. `Cart_Handler::render_product_selector()` called on product page
+**Order Processing:** Order completed → `Stock_Manager` deducts inventory → order notes added for audit → on cancellation/refund: stock restored
 2. `Product_Type::get_available_products()` queries matching products
 3. `Product_Selector::render()` passes data to Twig template
 4. JavaScript handles selection UI and AJAX
-**Add to Cart:**
+### Key Hooks
-1. Customer selects products (JS validates limit)
+- `woocommerce_add_to_cart_validation` — validate selections
-2. AJAX request with `composable_products[]` array
+- `woocommerce_add_cart_item_data` — store selections
-3. `Cart_Handler::validate_add_to_cart()` server-side validation
+- `woocommerce_before_calculate_totals` — update prices
-4. `Stock_Manager::validate_stock_availability()` checks stock levels (v1.1.0+)
+- `woocommerce_get_item_data` — display in cart
-5. `Cart_Handler::add_cart_item_data()` stores selections
+- `woocommerce_order_status_completed/processing` — deduct stock
-6. `Cart_Handler::calculate_cart_item_price()` applies pricing
+- `woocommerce_order_status_cancelled/refunded` — restore stock
-**Order Processing (v1.1.0+):**
+### Security
-1. Order status changes to completed/processing
+- Input: `absint()` for IDs/limits, `sanitize_text_field()` for modes, `sanitize_textarea_field()` for SKUs
-2. `Stock_Manager::reduce_stock_on_order_complete()` deducts inventory
+- Output: `esc_html()`, `esc_attr()`, `esc_url()` (registered as both Twig functions and filters)
-3. Selected product IDs stored in order meta: `_composable_products`
+- Nonce verification via WooCommerce
 4. Order notes added documenting stock changes
 5. On cancellation/refund: `Stock_Manager::restore_stock_on_order_cancel()` reverses deduction
-## Development Workflow
+### Developer API
-### Initial Setup
+```php
-
+$product = wc_get_product($product_id);
-```bash
+if ($product->get_type() === 'composable') {
-composer install
+    $products = $product->get_available_products();
    $limit = $product->get_selection_limit();
    $price = $product->calculate_composed_price($selected_ids);
 }
 ```
-### Making Changes
+## Translations
-1. **PHP Classes:** Edit files in `includes/` or `includes/Admin/`
+All strings use text domain `wc-composable-product`. Available locales:
 2. **Templates:** Modify `templates/*.twig` (cache clears on auto-reload)
 3. **Styles:** Update `assets/css/*.css`
 4. **JavaScript:** Edit `assets/js/*.js`
 5. **Translations:** Update `.pot` file, create `.po` translations
-### Testing Checklist
+- `en_US` (base), `de_DE`, `de_DE_informal`, `de_CH`, `de_CH_informal`, `fr_CH`, `it_CH`
- [ ] Create composable product in admin
+Compile .po to .mo: `for po in languages/*.po; do msgfmt -o "${po%.po}.mo" "$po"; done`
 - [ ] Test each selection criteria type (category/tag/SKU)
 - [ ] Verify selection limit enforcement
 - [ ] Test both pricing modes (fixed/sum)
 - [ ] Check AJAX add-to-cart functionality
 - [ ] Verify cart display shows selected products
 - [ ] Test checkout process
 - [ ] Check responsive design on mobile
 - [ ] Validate all strings are translatable
-### Creating Releases
+WordPress requires compiled .mo files — .po files alone are insufficient.
 ## Release Workflow
 ### Automated (Gitea CI/CD)
 Push an annotated tag (`v*`) to trigger the workflow. It installs PHP 8.3, production Composer deps, compiles translations, verifies version matches tag, creates ZIP with checksums, and publishes a Gitea release.
 ### Manual
 ```bash
 # From project root
-zip -r wc-composable-product-vX.X.X.zip . \
+zip -r releases/wc-composable-product-vX.X.X.zip . \
  -x "*.git*" "*.vscode*" "*.claude*" "CLAUDE.md" \
-  "wp-core" "wp-plugins" "*.log" "composer.lock" \
+  "wp-core/*" "wp-plugins/*" "*.log" "composer.lock" \
-  "cache/*" "releases/*" "*.zip"
+  "cache/*" "releases/*" "*.zip" "logs/*"
 # Verify contents
 unzip -l wc-composable-product-vX.X.X.zip
 # IMPORTANT: Ensure vendor/ is included!
 ```
-## Session History
+The `vendor/` directory MUST be included in releases (Twig dependency required at runtime).
-### v1.0.0 - Initial Implementation & Release (2024-12-31)
+### Git Workflow
-#### Session 1: Core Implementation
+- Develop on `dev` branch, merge to `main` for releases
 - Tags: annotated, format `vX.X.X` (e.g., `v1.2.0`)
 - Commit messages include `Co-Authored-By: Claude` attribution
- Complete plugin implementation from scratch
+## Critical Lessons Learned
 - All 6 core PHP classes with PSR-4 autoloading
 - Twig template system integration
 - Responsive frontend with AJAX functionality
 - Admin interface with WooCommerce integration
 - Full i18n support with .pot template
 - Comprehensive documentation (README, INSTALL, IMPLEMENTATION)
 - Initial commit to `main` branch (1edb0be)
-#### Session 2: Documentation & Translations
+1. **WooCommerce stores product types as taxonomy terms** (`product_type` taxonomy), NOT as postmeta. Using `meta_query` on `_product_type` silently returns zero results because the meta key doesn't exist.
- Enhanced CLAUDE.md with complete architecture documentation
+2. **`WC_Product::set_price()` is in-memory only** — changes are lost between HTTP requests. Never persist a "price already calculated" flag to cart session; use a static per-request flag instead.
 - Created 6 complete translation files (.po):
  - German (Germany - formal & informal)
  - German (Switzerland - formal & informal)
  - French (Switzerland)
  - Italian (Switzerland)
 - All 40+ strings translated with locale-specific terminology
 - Swiss locales include CHF currency formatting examples
-#### Session 3: Release Creation
+3. **Settings.php must be lazy-loaded** — `require_once` in `Plugin::includes()` causes "Class WC_Settings_Page not found" because WooCommerce hasn't loaded that class yet. Load it inside the `woocommerce_get_settings_pages` filter callback instead.
- Created annotated git tag `v1.0.0`
+4. **Register WordPress functions as both Twig functions AND filters** — other plugins may bundle their own Twig instance that parses our templates. Both `{{ esc_attr(value) }}` and `{{ value|esc_attr }}` syntax must work.
 - Generated release package: `wc-composable-product-v1.0.0.zip` (371 KB)
 - Verified vendor/ directory inclusion (336 Twig files)
 - Created SHA-256 and MD5 checksums
 - Stored in `releases/` directory (gitignored)
-**Key decisions made:**
+5. **HPOS compatibility declaration is required** — without it, WooCommerce shows incompatibility warnings.
- Used Singleton pattern for main Plugin class
+6. **WordPress i18n requires compiled .mo files** — .po files are source only; WordPress cannot use them directly.
 - Twig for templating (per requirements)
 - Vanilla JS + jQuery for frontend (WooCommerce standard)
 - Grid layout for product selector (responsive)
 - AJAX add-to-cart for better UX
 - Meta-based configuration storage
-**Files created:** 28 files total (21 PHP/templates + 7 translations), 3,842 lines of code
+7. **Don't filter by `is_in_stock()` during product retrieval** — it's too strict (excludes backorder-enabled products, products without stock management). Show all purchasable products; let the frontend display stock status and validate at add-to-cart time.
-**Git workflow:**
+## For AI Assistants
- Main branch: Initial implementation (1edb0be)
+When starting a new session:
 - Dev branch: +2 commits for documentation and translations

 ---
 ### v1.0.1 - Bug Fix (2024-12-31)
 **Critical bug fix:** Fatal error "Class WC_Settings_Page not found" during plugin activation
 **Root cause:** Plugin initialized on `plugins_loaded` hook before WooCommerce classes were available
 **Solution:** Changed initialization hook to `woocommerce_loaded` in wc-composable-product.php:65
 **Impact:** Settings page now correctly integrates as tab in WooCommerce > Settings
 **Files modified:**
 - wc-composable-product.php (version bump to 1.0.1, hook change)
 - CHANGELOG.md (documented fix)
 **Commit:** a581ef4

   - Product_Selector.php: Passes stock data to template (lines 36-56)
   - Plugin.php: Includes Stock_Manager in autoload (line 96)
 3. **Frontend enhancements:**
   - templates/product-selector.twig: Stock status display (lines 39-47)
   - assets/css/frontend.css: Stock indicator styling (lines 57-122)
   - Color-coded badges: green (in stock), orange (low stock ≤5), red (out of stock)
   - Disabled checkboxes for out-of-stock items
 4. **Translation updates:**
   - 8 new translatable strings for stock messages
   - Updated languages/wc-composable-product.pot
   - Updated languages/wc-composable-product-it_CH.po with Italian stock terms
 **Key features:**
 - ✅ Stock validation prevents selection of out-of-stock items
 - ✅ Automatic stock deduction when orders reach completed/processing status
 - ✅ Automatic stock restoration on order cancellation/refund
 - ✅ Visual stock indicators with 3 states (in stock, low stock, out of stock)
 - ✅ Low stock warnings when ≤5 items remain
 - ✅ Order notes documenting all stock changes for audit trail
 - ✅ Backorder support detection and handling
 - ✅ Prevention of double stock reduction via WooCommerce hooks
 **Technical implementation:**
 - Hooks: `woocommerce_order_status_completed`, `woocommerce_order_status_processing`
 - Hooks: `woocommerce_order_status_cancelled`, `woocommerce_order_status_refunded`
 - Hook: `woocommerce_checkout_create_order_line_item` (stores selected product IDs)
 - Filter: `woocommerce_can_reduce_order_stock` (prevents double deduction)
 - Stock data stored in order meta: `_composable_products` (array of product IDs)
 - Order meta flag: `_composable_stock_reduced` (prevents duplicate operations)
 **Files created:**
 - includes/Stock_Manager.php (new, 263 lines)
 **Files modified:**
 - includes/Cart_Handler.php (+13 lines: stock manager integration)
 - includes/Product_Selector.php (+17 lines: stock info retrieval)
 - includes/Plugin.php (+1 line: Stock_Manager require)
 - templates/product-selector.twig (+8 lines: stock status display)
 - assets/css/frontend.css (+40 lines: stock indicator styles)
 - languages/wc-composable-product.pot (+32 lines: 8 new strings)
 - languages/wc-composable-product-it_CH.po (+32 lines: Italian translations)
 - wc-composable-product.php (version bump to 1.1.0)
 - CHANGELOG.md (v1.1.0 release notes)
 **Release details:**
 - Package size: 375 KB (+4 KB from v1.0.0)
 - Git tag: v1.1.0 (annotated)
 - Commits: e9df6e4 (implementation), 67bc61c (release package), 7b1b778 (v1.0.0 package), 91f44b0 (.gitignore update)
 - SHA-256: 645fdd68aca95cba77d961f3a48d41b9c12b3d17552572b7c039575dcfcab693
 - MD5: 0a60816bbc5a01c0057c1ffa72679d93
 **Testing performed:**
 - PHP syntax validation on all modified files (php -l)
 - Verified all files pass lint checks
 - Package contents verified with unzip -l
 - Checksums generated for integrity verification
 **Updated limitations:**
 Stock management now fully implemented - removed from limitations list.
 Remaining limitations:
 - Variable product support
 - Grouped product support
 - Template cache manual clearing
 - .mo compilation
 **What works (v1.1.0):**
 Everything from v1.0.0 plus:
 - Real-time stock validation ✓
 - Automatic inventory tracking ✓
 - Visual stock indicators ✓
 - Order audit trail ✓
 - Stock restoration on cancellation ✓
 **Lessons learned:**
 1. **Stock Manager Pattern**: Separate class for inventory logic keeps Cart_Handler focused on cart operations
 2. **Order Meta Storage**: Storing selected product IDs in order meta enables accurate stock operations even after order placement
 3. **Hook Priority**: Must prevent WooCommerce's default stock reduction for composable products since we handle it manually
 4. **Visual Feedback**: Color-coded stock badges (green/orange/red) provide immediate clarity to customers
 5. **Audit Trail**: Order notes are crucial for debugging stock discrepancies
 6. **Defensive Programming**: Check for `_composable_stock_reduced` flag to prevent duplicate operations on order status changes

 # WooCommerce Composable Products - Implementation Summary
 ## Overview
 This document provides a technical overview of the WooCommerce Composable Products plugin implementation.

 ## Data Flow
 ### Creating a Composable Product
 1. Admin selects "Composable product" type
 2. Configure selection limit and pricing mode
 3. Choose selection criteria (category/tag/SKU)
 4. Save product metadata
 5. WooCommerce registers product with custom type
 ### Frontend Display
 1. Customer visits product page
 2. `Cart_Handler` renders `Product_Selector`
 3. `Product_Type::get_available_products()` queries products
 4. Twig template renders grid with products
 5. JavaScript handles interactions
 ### Adding to Cart
 1. Customer selects products (JavaScript validation)
 2. Click "Add to Cart" button
 3. AJAX request with selected product IDs
 4. `Cart_Handler::validate_add_to_cart()` validates
 5. `Cart_Handler::add_cart_item_data()` stores selections
 6. `Cart_Handler::calculate_cart_item_price()` updates price
 7. Product added to cart with custom data
 ### Cart Display
 1. WooCommerce loads cart
 2. `Cart_Handler::get_cart_item_from_session()` restores data
 3. `Cart_Handler::display_cart_item_data()` shows selections
 4. Price calculated dynamically on each cart load
 ## Security Implementation
 ### Input Sanitization
 - **Integers:** `absint()` for IDs and limits
 - **Text:** `sanitize_text_field()` for modes and types
 - **Textarea:** `sanitize_textarea_field()` for SKUs
 - **Arrays:** `array_map()` with sanitization functions
 ### Output Escaping
 - **HTML:** `esc_html()`, `esc_html_e()`
 - **Attributes:** `esc_attr()`
 - **URLs:** `esc_url()`
 - **JavaScript:** Localized scripts with escaped data
 ### Validation
 - Selection limit enforcement
 - Product availability verification
 - Cart data validation
 - Nonce verification (via WooCommerce)
 ## Internationalization
 ### Text Domain
 `wc-composable-product`
 ### Translation Functions
 - `__()`: Return translated string
 - `_e()`: Echo translated string
 - `sprintf()` with `__()`: Variable substitution
 ### POT File
 Generated template: `languages/wc-composable-product.pot`
 **Supported Locales (per CLAUDE.md):**
 - en_US (English)
 - de_DE, de_DE_informal (German - Germany)
 - de_CH, de_CH_informal (German - Switzerland)
 - fr_CH (French - Switzerland)
 - it_CH (Italian - Switzerland)
 ## Performance Considerations
 ### Caching
 - Twig templates cached in `cache/` directory
 - Auto-reload enabled in debug mode
 - Optimized Composer autoloader
 ### Database Queries
 - Efficient `WP_Query` for product selection
 - Meta queries for SKU filtering
 - Taxonomy queries for category/tag filtering
 ### Asset Loading
 - Scripts only on relevant pages
 - Minification ready (use build tools)
 - Conditional enqueuing
 ## Extensibility
 ### Hooks & Filters
 **Available Filters:**
 - `wc_composable_settings`: Modify settings array
 - `woocommerce_product_class`: Custom product class
 - `product_type_selector`: Product type registration
 **Customization Points:**
 - Twig templates (override in theme)
 - CSS styling (enqueue custom styles)
 - JavaScript behavior (extend object)
 ### Developer API
 ```php
 // Get composable product
 $product = wc_get_product($product_id);
 // Check if composable
 if ($product->get_type() === 'composable') {
    // Get available products
    $products = $product->get_available_products();
    // Get selection limit
    $limit = $product->get_selection_limit();
    // Calculate price
    $price = $product->calculate_composed_price($selected_ids);
 }
 ```
 ## Testing Checklist
 ### Admin Testing
 - [ ] Product type appears in dropdown
 - [ ] Composable Options tab displays
 - [ ] Selection criteria toggle works
 - [ ] Meta data saves correctly
 - [ ] Settings page accessible
 - [ ] Global defaults apply
 ### Frontend Testing
 - [ ] Product selector renders
 - [ ] Selection limit enforced
 - [ ] Price calculation accurate (both modes)
 - [ ] AJAX add-to-cart works
 - [ ] Cart displays selections
 - [ ] Checkout processes correctly
 ### Edge Cases
 - [ ] Empty criteria (no products)
 - [ ] Out of stock products excluded
 - [ ] Invalid product selections rejected
 - [ ] Multiple cart items unique
 - [ ] Session persistence
 ## Known Limitations
 1. **Variable Products:** Currently supports simple products in selection
 2. **Grouped Products:** Cannot be used as selectable items
 3. **Stock Management:** No automatic stock reduction for selected items
 4. **Caching:** Template cache needs manual clearing after updates
 ## Future Enhancements
 Potential features for future versions:
