Customer lifecycle
Model prospect, registered user, purchased evaluation, active account, passed, failed and funded states without conflating them.
Order and payment status
Keep purchase/payment state distinct from trading-account state and reconcile external provider events.
Provisioning
Trigger account creation through a controlled integration service and record platform identifiers.
Rule synchronization
Receive authoritative program results from the challenge/risk layer rather than recomputing rules inconsistently in multiple systems.
Support
Give support staff enough context to investigate status while restricting privileged platform actions.
Reporting
Track funnel and operational metrics with consistent customer, order and account identifiers.
Auditability
Record manual status changes and adjustments with actor and reason.
