CRITICAL FIX: WordPress plugin directory structure
Previous issue:
- ZIP contained files at root level
- WordPress created directory based on ZIP name: wc-composable-product-v1.1.7/
- This caused version-numbered directory in wp-content/plugins/
Corrected structure:
- ZIP now contains wc-composable-product/ parent directory
- All plugin files inside wc-composable-product/ directory
- WordPress extracts to wp-content/plugins/wc-composable-product/ (correct!)
Changes:
- Recreated ZIP with proper directory structure using rsync + zip
- Package size: 410 KB (419,697 bytes) - slightly larger due to parent dir
- New SHA-256: 866e7dd34431f4c881629fd8b59ddd3a27c7a45b7324a3d88cd064a3e01c1b83
- New MD5: 871fbb3b910380c0e43bcf1538408eda
WordPress standard: Plugin ZIP must contain single parent directory named after
the plugin slug, with all files inside that directory.

Fixed "Unknown 'esc_attr' filter" error that occurred when rendering
the product selector template. The issue was caused by WordPress
escaping functions being registered only as Twig functions, not filters.

- Added TwigFilter registrations for esc_html, esc_attr, esc_url
- Template now supports both filter syntax (|esc_attr) and function syntax
- Fixes compatibility issues when other plugins use their own Twig instances
- Version bump to 1.1.5

Document the critical bug fix journey for the WC_Settings_Page error:
v1.1.1 session (failed attempt):
- Attempted to fix with hook timing change
- Changed to woocommerce_init hook
- Bug persisted - error logs showed it still failed
- Lesson: Always verify fixes with error logs
v1.1.2 session (successful fix):
- Discovered root cause: Settings.php loaded too early
- require_once happened during Plugin::includes()
- PHP tried to parse 'extends WC_Settings_Page' before class existed
- Solution: Delayed require_once to add_settings_page() callback
- This callback runs when WC has loaded all settings classes
Key learnings documented:
1. Class loading order matters more than hook timing
2. Always verify fixes don't just assume they work
3. Lazy loading pattern for extending third-party classes
4. Read error logs thoroughly - backtrace reveals the sequence
5. Don't assume hook order means all classes are loaded
6. Test immediately after each release
Also documents the debugging approach that worked and the
5-version journey to finally fix this persistent issue.

Release v1.1.2 - CRITICAL bug fix for Settings.php class loading
This release fixes the persistent WC_Settings_Page error that affected all previous versions including v1.1.1.
Root cause:
- Settings.php extends WC_Settings_Page
- File was being required during Plugin::includes()
- WC_Settings_Page class didn't exist at that point
- Hook timing changes (v1.0.1, v1.1.1) were insufficient
Solution implemented:
- Removed require_once from Plugin::includes()
- Moved to Plugin::add_settings_page() callback
- Loads on-demand via woocommerce_get_settings_pages filter
- WC_Settings_Page guaranteed to exist at that point
Package contents:
- Plugin source files (v1.1.2)
- Stock management integration (v1.1.0 feature)
- Complete vendor dependencies (Twig 3.0)
- Translation files for 6 locales
- Documentation and changelog
Package size: 383 KB

CRITICAL BUG FIX: v1.1.1 still had the same error!
Root cause analysis:
- v1.1.1 changed hook to woocommerce_init but error persisted
- Real issue: Settings.php was require_once'd in Plugin::includes()
- At that point, class extends WC_Settings_Page which doesn't exist yet
- Even woocommerce_init fires before WC_Settings_Page is loaded
Solution:
- Removed require_once from Plugin::includes() (line 93)
- Moved require_once to Plugin::add_settings_page() (line 196)
- Settings.php now loads on-demand via woocommerce_get_settings_pages filter
- This filter fires when WooCommerce has loaded all settings classes
Changes:
- includes/Plugin.php: Delayed Settings.php inclusion with explanatory comment
- wc-composable-product.php: Version bump to 1.1.2
- CHANGELOG.md: Documented fix and noted v1.1.1 was insufficient
This addresses the actual root cause that persisted through 3 versions.

that prevented the plugin from activating successfully.
