/**
 * Expense Scenario A: Local Currency (ILS) Receipt Expense
 *
 * This scenario represents a simple expense paid in local currency (ILS) with a receipt.
 * It demonstrates the basic happy path for expense recording and ledger generation.
 *
 * Flow:
 * 1. Admin business purchases from Local Supplier Ltd
 * 2. Transaction recorded: -500 ILS (negative = expense/outflow)
 * 3. Receipt document provided matching the transaction
 * 4. Expected ledger: debit expense category, credit bank account
 *
 * Prerequisites:
 * - Admin business entity exists (from seed)
 * - General expense tax category exists (from seed)

 * Expense Scenario A: ILS Receipt Expense
 *
 * @description
 * A local supplier provides a service, admin pays 500 ILS, receives a receipt.
 * This is the simplest expense case with matching transaction and document.
 *
 * @example
 * ```typescript
 * import { expenseScenarioA } from './fixtures/expenses/expense-scenario-a';
 * import { insertFixture } from './helpers/fixture-loader';
 *
 * await withTestTransaction(pool, async (client) => {
 *   await seedAdminCore(client); // Ensure admin context exists
 *   const idMap = await insertFixture(client, expenseScenarioA);
 *
 *   // Now test ledger generation
 *   const chargeId = idMap.get('charge-office-supplies');
 *   // ... trigger ledger generation and assert
 * });
 * ```
