## 📌 Core Business Logic

### 1. Financial Ledger & Snapshots
* `FinancialTransaction` records every income/expense across POS, Savings, Loans, Payouts
* Monthly snapshots archived in `FinancialReportSnapshot`

### 2. Bank Reconciliation
* Bank statements (CSV) imported via `AuditBankImport`
* Auto-categorization via `AuditBankCategoryRule` (regex pattern matching on descriptions)

### 3. RAT Financial Statements
* `RatDetailService` aggregates multi-year comparative data, merges ledger + manual entries
