FHIR is an interface contract, not a trust shortcut
A CelestyxAI interoperability note on LLM-assisted clinical structuring, schema validation and governed exchange.
LLMs can reduce the cost of mapping and structuring clinical data, but syntactic FHIR validity is not the same as semantic or clinical correctness. Interoperability needs deterministic validation and provenance.
Pipeline principle
Free text may be normalized with model assistance, but the resulting resource should pass schema constraints, terminology checks, required-field checks and explicit reject/review paths before downstream exchange.
Model independence
The interchange contract should survive model replacement. This argues for a stable structured domain model between the clinical policy layer, AI orchestration and external FHIR interfaces.
Institutional implication
FHIR readiness should be presented as an architectural direction until a real partner integration is validated; the website should not imply an active EHR integration where none exists.
This brief is a CelestyxAI synthesis of the cited external evidence and accumulated project design decisions. It is not a peer-reviewed scientific publication and does not establish clinical efficacy.
