# Clinical Exam Request Portal

The optional `clinical_exam_requests` module lets authenticated hospital clinicians request radiology examinations and lets authorized radiology staff review them.

Enable it in **Administration > Settings > Modules**. It is disabled by default; disabling it hides and blocks the portal without deleting requests.

## Workflow

`Draft -> Submitted -> Accepted`, `Clarification Required`, or `Rejected`.

Accepted requests create a linked RIS Study in a database transaction. The submitted clinical source and append-only decision history remain preserved. Emergency selection never replaces direct escalation to radiology.

## Access

- Requesters need `view_exam_request_portal`, `create_exam_requests`, and `submit_exam_requests`.
- Radiology reviewers need `review_exam_requests`.
- Users see only their own requests unless they are reviewers.

Open public registration is intentionally not supported. Accounts must be created and approved by hospital administration.
