+# Accounting Audit Unlink Tracker
+
+This Odoo module tracks deletion operations for critical business records and ensures they are recorded in the **Accounting Audit Trail** report.
+
+## Features
+
+- **Deletion Tracking**: Automatically intercepts `unlink` calls for major models.
+- **Persistent Logs**: Creates audit logs with `res_id = 0` so history survives record deletion.
+- **Detailed Information**: Logs capture:
+  - User responsible for deletion.
+  - Record Technical ID.
+  - Record Display Name.
+  - Model Name.
+- **Audit Trail Integration**: Logs appear directly in the standard **Accounting > Reporting > Audit Trail** report.
+
+## Supported Models
+
+- **Accounting**: `account.move`, `account.account`, `account.tax`
+- **Core/Partners**: `res.partner`, `res.company`
+- **Manufacturing**: `mrp.production`, `mrp.bom`
+- **Inventory/Logistics**: `stock.picking`, `stock.move`, `stock.lot`
+- **Products**: `product.template`, `product.product`, `product.category`
+- **Sales/Purchase**: `sale.order`, `purchase.order`
+- **HR**: `hr.employee`
+
+## Installation
+
+1. Add the module to your custom addons path.
+2. Update the addon list in Odoo.
+3. Install `account_audit_unlink`.
+
+## Usage
+
+Go to **Accounting > Reporting > Audit Reports > Audit Trail** to view all deletion logs alongside standard audit trails.
