SCRIMED Production Architecture v1
AI-native healthcare infrastructure with agents, trust, context, model routing, evals, ClinSecOps, and workflow controls.
SCRIMED now exposes a governed architecture contract for the next platform layer: persistent agent runtime, PHI-safe context handling, Trust Engine v2, vendor-neutral model routing, continuous evaluation, ClinSecOps, and deterministic workflow execution. The current state remains synthetic, metadata-only, and human-review gated.
GO / NO-GO
NO-GO for live clinical production. GO for governed synthetic evaluation, buyer diligence, architecture review, and no-PHI pilot preparation.
SCRIMED Production Architecture v1 is a synthetic, metadata-only, review-gated architecture contract. It does not authorize PHI processing, live patient data use, autonomous diagnosis, autonomous treatment, prescribing, patient outreach, payer submission, EHR writeback, claim submission, HIPAA/SOC/FDA certification, or clinical production approval.
01No PHI processing authority
02No live patient data
03No autonomous diagnosis, treatment, prescribing, or patient instruction
04No payer submission, claim submission, final coding, billing action, or reimbursement guarantee
05No EHR writeback, record finalization, or production connector use
06No HIPAA, SOC, HITRUST, FDA, ONC, or security certification claim
07No production model routing without contracts, privacy/security approval, telemetry, fallback, and human review
Architecture layers
Seven layers convert SCRIMED from product surfaces into a governed healthcare intelligence operating system.
