Components – Operation Module

The Operation module manages movements, alerts, and communications. It follows a hexagonal architecture — the BFF calls it through an inbound service interface, and persistence is abstracted behind outbound repository interfaces.

Components

Component	Technology	Role
Operation Service Interface	Kotlin Interface	Inbound port — exposes all domain operations to the BFF
Movement Service	Kotlin / Domain	Records departures and returns for participants
Alert Service	Kotlin / Domain	Creates and manages alerts, independent of movement state
Communication Service	Kotlin / Domain	Manages communication threads attached to alerts
Repository Interfaces	Kotlin Interface	Outbound port — persistence contracts defined by the domain
Repositories	jOOQ / R2DBC	Outbound adapter — implements repository interfaces against the operation schema
