The Lock-First pattern solves the problem of auto-fill systems silently overwriting user-entered data. By adding explicit boolean lock flags (e.g., is_end_date_locked) to data models, developers can clearly define whether the system or the user owns a given field. The pattern involves three steps: adding lock flags to the database schema, checking lock state before applying auto-calculations in business logic, and surfacing the lock state visually in the UI with a toggle. This approach eliminates silent data loss, enables audit trails via source tracking, and supports both automated defaults and manual overrides in the same workflow.
