v1.2.0 - Fix product selection, cart pricing, admin tabs + CI/CD

Fix three critical bugs that persisted through v1.1.11-v1.1.14:

- Product selection always empty: meta_query checked _product_type in
  postmeta, but WooCommerce uses the product_type taxonomy. Replaced
  with correct tax_query using NOT IN operator.
- Cart price always 0.00: composable_price_calculated flag persisted
  in session, preventing recalculation on page loads. Removed flag;
  static variable already handles per-request dedup.
- Admin tabs both visible on load: JS now triggers WooCommerce native
  tab click instead of manually toggling panel visibility.

Add Gitea CI/CD release workflow triggered on v* tags.

+## [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
