Shared Kernel / ACL

Shared Kernel (concepts used across contexts): - Money Amount: Monetary value with currency information - Date Range: Time periods used in budgets, reports, and bills - Account Reference: Lightweight account identifier used across contexts - Transaction Reference: Basic transaction information for cross-context operations

Anti-Corruption Layer (ACL) boundaries: - External Data Sources: Import context translates bank formats to internal transaction model - Reporting Engine: Transforms internal data models into presentation-friendly formats - API Layer: Converts internal domain models to REST API representations - Database Schema: ORM layer translates between domain objects and database tables

Context Relationships: - Transaction Processing ↔ Account Management: Transactions must reference valid accounts - Budget Management ↔ Transaction Processing: Budget tracking requires transaction categorization - Bill Tracking ↔ Transaction Processing: Bill matching against actual transactions - Rule Engine ↔ Transaction Processing: Rules process and modify transactions - Categorization ↔ Transaction Processing: Categories and tags applied to transactions

Integration Points: - Account balances calculated from transaction history - Budget progress derived from categorized transactions - Bill matching based on transaction patterns - Reports aggregate data across multiple contexts
