# BCOS Build Sprint 11 — Client and Relationship Management

## Delivered
- Client/organization CRUD foundation
- Search, status and classification filtering
- Duplicate candidate scoring and override control
- Archive and restore
- Contacts, stakeholders and relationship history
- Client project and financial summary views
- Permission-scoped endpoints
- Responsive React list and detail screens
- Unit and static implementation tests

## Security controls
- Every endpoint requires authentication and an explicit permission.
- Financial summaries require `clients.view_financials`.
- Client creation blocks likely duplicates unless an authorized override reason is supplied.
- Archive and restore create audit events.
- Relationship history carries a security classification.

## Production limitations
- Scope filtering currently supports the architecture hook but requires a finalized office/client assignment middleware.
- Database integration must be run on a MySQL/MariaDB environment.
- Contact update/archive and organization merge UI are planned for a follow-up hardening sprint.
- React components are integration-ready but must be wired into the existing application router and design system.
