 ### 1. Dynamic Sequences
 - **Employee Reimbursement (RMBS)**: Expenses paid by the employee follow the prefix `RMBS/YYYY/MM/XXXXX`.
-*   **Company Advance (KSBN)**: Expenses paid by the company (Kasbon) follow the prefix `KSBN/YYYY/MM/XXXXX`.
-*   This ensures clear separation between standard reimbursements and company-issued advances at a glance.

-### 2. Enhanced Status Workflow
+### 2. Enhanced Status Workflow (Odoo 19 Refined)
 - **Wait Post Status (Yellow)**: A new intermediate status for company-paid expense reports. 
 - **Workflow**: `Approved` -> `Posted` -> **`Wait Post`** -> `Done`.
 - **Logic**: The report moves to **Wait Post** after the advance is paid. It stays here until the employee submits all receipts and the accountant posts the final realization journal.
 - **Done (Green)**: Only reached when all realization accounting is completed, ensuring the physical and financial cycles are fully synchronized.
+- **Architectural Note**: In Odoo 19, the legacy `hr.expense.sheet` logic has been merged directly into the core `hr.expense` model for better performance and consistency.
 
-### 3. Account Splitting
+### 3. Account Splitting & Kasbon Logic
 - **Dynamic Selection**: Automatically routes expenses to different GL accounts based on the `Paid By` field.
 - **Configuration**: Set distinct `Expense Account (Employee)` and `Expense Account (Company)` directly on the Expense Category form.
+- **Advance Account**: Company-paid advances (Kasbon) use account **115101** for the debit side of the initial payment journal entry.
 
-### 4. Anonymous Expense Kiosk
+### 4. Journal Entry Safeguards
+- **Reversal Protection**: The **Reverse Entry** button is automatically hidden on journal entries linked to expenses. This prevents accidental reversals that would cause the accounting ledger to fall out of sync with the expense status.
+
+### 5. Anonymous Expense Kiosk
 - **PIN-Protected Access**: Secure employee login via a 4-digit PIN on a tablet interface.
 - **Real-Time Totaling**: Automatically summarizes multiple physical receipts into a single realization.
 - **Image Optimization**: Client-side JPEG compression (1024px, 70% quality) reduces server storage usage by ~90%.
 
-### 5. Automated Realization Accounting
+### 6. Automated Realization Accounting
 - **Balanced Journal Entries**: Automatically calculates discrepancies between the advance paid and actual spending.
 - **Discrepancy Accounts**:
   - **Over-spent (Spent > Paid)**: Balance is moved to `216109 Biaya Lain yang masih harus dibayar` (Liability/Payable).

   - **Create Vendor Payment**: One-click button on the realization form to pay the employee the difference.

-### 6. Validation & Security
-- **Mandatory Receipts**: Prevents submission of employee-paid expenses without attachments.
-- **Overdue Tracking**: Highlights missing realization receipts in red/alerts for company-paid expenses.
