Clinical order and service request
A request by an authorized practitioner for a diagnostic test, imaging, a procedure, a consultation or a referral, with its status, the performing party and the link to results. Medication prescriptions are a separate contour.

Published results
The independent second-provider study, fixtures and the full research protocol remain open. Runtime promotion is governed by the package allocation holds.

Deep research questions
- How is an order kept separate from its fulfilment by another department or provider?
- How are verbal orders recorded and later signed?
- How is a result linked to the order without the order changing its meaning?
Verifiable invariants
- Every order names the ordering practitioner and the time of ordering
- A cancelled order keeps who cancelled it and why
- A result references the order it answers
End-to-end acceptance scenario
For a synthetic outpatient visit, place a laboratory order and a referral, record a verbal order signed later, receive a result for the laboratory order and track the referral to its acceptance.
Negative case
A result that arrives without a matching order is attached to the most recent order of the same type, and the clinician reads it as the answer to a different question.
