Architecture Teardown: Real-time ambient clinical encounter to structured FHIR with pediatric dose guardrail

Dr. Priya Sharma, MD & David ChenOriginal Author
We hooked local Whisper STT into a Claude Code agent running on a clinician laptop. It listens to a doctor-patient conversation, creates the visit summary, extracts the medication order, checks the child weight in our local SQLite table, and prints the verified script, all in under two seconds.
CLINICAL BENCHMARK // AMBIENT PIPELINE VERIFIED PRIMARY RECORD
Statutory / Clinical Citation: KŌS Invariant Verification Protocol #089-A
“All ambient transcription pipelines must route through a deterministic parameter barrier before executing prescription dispatch or diagnostic order generation.”
