## Overview

1. **This is a WordPress/WooCommerce plugin, not a standalone app.**  
   The shipped code lives under `src/` and is activated through the main plugin bootstrap file `src/wpwing-smart-wishlist-product-waitlist-for-woocommerce.php`. Everything else in the repo is either supporting runtime code, build/dev tooling, or tests.

2. **The plugin is split into four main runtime layers: Core, Admin, Frontend, and feature modules.**  
   - `Core/` handles lifecycle, persistence, settings, cron, GDPR, and deletion hooks.  
   - `Admin/` contains WordPress dashboard pages and list tables.  
   - `Frontend/` handles conditional CSS/JS loading.  
   - `Wishlist/` and `Waitlist/` contain the actual user-facing feature flows.

3. **Core is the orchestration boundary.**  
   `Core/Plugin.php` is the central boot sequence/singleton that wires hooks and loads the rest of the plugin. `Activator.php` creates data structures on activation, `Settings.php` wraps WordPress options, `Database.php` centralizes table naming, and `Cron.php` schedules cleanup tasks. `GdprHandler.php` and `ProductDeleteHandler.php` connect the plugin to WordPress compliance and product lifecycle events.

4. **The plugin uses custom database tables instead of storing everything in post meta.**  
   The README explicitly calls out “custom database tables for performance.” That means the key architectural boundary is between WordPress/WooCommerce native entities (products, users, sessions, options) and plugin-owned tables used for wishlist and waitlist records. This is important for diagramming because the plugin is not just a thin UI layer; it owns its own persistence model.

5. **Wishlist and waitlist are separate feature pipelines with similar structure.**  
   Each feature has:  
   - a frontend renderer,  
   - an AJAX controller,  
   - and a guest merge handler for logged-out users who later authenticate.  
   Wishlist lives in `src/app/Wishlist/`, waitlist in `src/app/Waitlist/`. This separation matters because they are related but independent data flows.

6. **Frontend interaction is mostly AJAX-driven and uses small asset bundles.**  
   `assets/js/wpwing-wishlist.js` and `assets/js/wpwing-waitlist.js` handle client-side requests. `Frontend/Assets.php` enqueues the shared CSS/JS only when needed, keeping the plugin lightweight. The frontend PHP templates in `src/templates/` render the shortcode/UI markup that these scripts enhance.

7. **The wishlist flow is centered on product intent capture.**  
   `FrontendWishlist.php` renders the wishlist button/shortcode output, `WishlistController.php` processes toggle/check requests, and `GuestMergeHandler.php` merges guest selections into a user account after login. `AdminWishlist.php` provides an admin-side view of stored wishlist data.

8. **The waitlist flow is centered on back-in-stock subscription and notification.**  
   `FrontendWaitlist.php` renders the email capture form and shortcode output, `WaitlistController.php` handles join/leave actions and downstream notifications, and `GuestMergeHandler.php` preserves anonymous intent across login. The templates `waitlist-form.php` and `waitlist-view.php` define the markup boundary for this feature.

9. **Admin functionality is operational, not content-authoring.**  
   `AdminMenu.php` adds plugin pages to the WordPress dashboard, `AdminSettings.php` exposes settings screens, `AdminWaitlist.php` surfaces waitlist entries, and `WelcomeNotice.php` handles a one-time activation notice. This subsystem is for configuration and operational oversight rather than end-user shopping behavior.

10. **The plugin integrates with WooCommerce and WordPress lifecycle events.**  
   Key cross-cutting triggers are activation, product deletion, login/guest merge, cron, and GDPR export/erasure hooks. Those are the main edges where the plugin connects into the host platform, so an architecture diagram should show these as event-driven integrations rather than direct user-facing services.

11. **Repository tooling is split cleanly from runtime code.**  
   Root-level `composer.json`, `Makefile`, PHPCS/PHPStan config, PHPUnit, and Playwright are dev/test tooling. `docker-compose.yml` plus `docker/` provide a local WordPress/PHP/Caddy environment. `dist/` is the release artifact boundary, while `tests/` cover unit and end-to-end behavior.

12. **Net effect: one plugin, two customer-intent products, shared infrastructure.**  
   The shared infrastructure is the important architectural idea: both wishlist and waitlist use the same plugin bootstrap, settings, assets pipeline, admin shell, and lifecycle handlers, while keeping their UI and controllers separate. That makes the diagram naturally split into a common core with two feature branches feeding a shared persistence layer.
