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.

CHANGELOG.md

@@ -5,6 +5,143 @@ 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)

-## 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
