# User lifecycle and account journeys

Accounts, identity links, membership, MFA and recovery portal, advisory catalog.

## Reuse boundary

Application readback is advisory; applications must enforce their own authorization.

## Supported use cases

- U02: Human signs in with MFA and manages account or factor recovery
- U03: Application combines identity, tenant and resource facts and enforces a bound decision
- U10: Operator recovers identity, custody or data with independently held recovery material

## Evidence and integration

- [SCOPE.md](../../SCOPE.md)
- [README.md](../../README.md)

Assessment: CUST-WP-0081, 2026-10-14. Relations identify interfaces to compose; they do not certify native integration. Existing external evidence levels are retained where present. New entries use conservative C1/R0 until consumer assessment exists.
