MEDITECH Expanse / Greenfield Workspace on US Core STU6. Read-only at the OAuth tier — patient/*.write is silently dropped at consent. Plain SNOMED CT and LOINC systems, standard HL7 code systems, no preflight rejections.
Requesting a write scope does not fail. It succeeds, and the granted scope set comes back without it. An integration that checks only for an error and not for the granted scopes will believe it can write, and will discover otherwise on the first POST at a customer site. Comparing requested against granted scopes is the test this reproduces.
MEDITECH is the least mutated of the three vendor shapes: standard terminology systems, no proprietary OID dual-coding, no preflight search rejections. That makes it a useful control — a difference that shows up against Epic or Oracle Health but not here is a vendor quirk, not a bug in your client.
MEDITECH's published CapabilityStatement describes one shape; production deploys at least six. CapabilityStatement provenance is captured for all of them; the multi-patient element-deviation sweep is in progress, with richer overlays available today for Epic and Oracle Health (Cerner).
