 Since Apps Script functions must be top-level to be triggered or attached to buttons, `src/global.ts` explicitly exposes necessary functions from the modules to the global scope.
 
+### 5. Status Automation (`src/statusHandlers.ts`)
+
+A modular system handles changes to the `status` column. It uses a registry of `StatusHandler` implementations:
+- **Published**: Sets Shopify Status `ACTIVE`, Quantity `1`.
+- **Sold/Artist Swap**: Sets Shopify Status `ACTIVE`, Quantity `0`.
+- **Drafted**: Sets Shopify Status `DRAFT`.
+
 ## Triggers
 
 Triggers are managed programmatically via `src/triggers.ts`. Running `reinstallTriggers` will wipe existing project triggers and set up the standard set:
-- `onEdit` -> `newSkuHandler`
-- `onEdit` -> `matchProductToShopifyOnEditHandler`
-- `onEdit` -> `onEditQueue`
+- `onEdit` -> `onEditHandler` (Main Router)
 - `TimeBased (1 min)` -> `processBatchedEdits`
+- `TimeBased (10 min)` -> `checkRecentSales`
