Platform atlas
A 35-domain reference model for how care, operations, revenue and evidence connect without collapsing responsibility into one shared system boundary.
35
bounded domains / 5 operating wings
This atlas describes ownership, boundaries and handoffs. It is an architecture reference, not a statement that every domain is deployed or included in a facility proposal.

Stops here
Owns specimens and verified results; the ordering domain owns clinical intent.
Laboratory scope detail
Delivery patterns are source-backed facility models. Specialties and functions are architecture scoping examples for discovery—not proof that each capability is deployed.
