Determinism first
The rule engine identifies structured findings before any draft is written. AI never invents clinical facts.
How it works
Four phases.
Determinism first.
Clinician final.
A bounded decision-support flow that unifies messy real-world data, runs it through versioned rules, surfaces only what matters today, and routes every action through the licensed clinician.

The flow§ I
From source data to a clinician decision —
in a single, bounded loop.
Each phase is independently auditable. Each phase can be paused, amended, or rolled back without affecting the others.
- Iphase 01 of 04
Unify the data the patient already has.
Pull genomic reports, lab panels, medication lists, problem lists, allergy lists, and wearable summaries into one FHIR-shaped patient context. Every field carries its source.
Standards in playSMART-on-FHIR · HL7 v2 · VCF · CSV · OCR - IIphase 02 of 04
Interpret with deterministic rules — not vibes.
Versioned rules check phenotype calls against active medications, lab thresholds against medication context, and wearable trends against initiation events. The rule engine fires before any language model touches the chart.
Standards in playCPIC level A · PharmGKB 1A · ADA · AHA / ACC · USPSTF - IIIphase 03 of 04
Surface the small set that matters today.
From a typical chart of 8+ findings, the platform pulls forward the 1-3 items tied to today's appointment. Longitudinal context collapses behind a single expander so the today view stays clean.

Guardrails§ II
Deterministic rules first.
Language models second.
Clinician always final.
The product is built around a posture that puts evidence and reversibility ahead of speed.
Cited or it doesn't ship
Every recommendation references a guideline source (CPIC / PharmGKB / USPSTF / ADA / AHA) and a versioned rule ID.
Reversible by design
Accept, dismiss, snooze, amend — all logged. Nothing the platform does is uneditable.
Clinician-final
Medication changes are made only by the licensed clinician. The product is decision support, not a prescriber.
4Phases. Each independently auditable, reversible, and version-snapshotted.
100%Of recommendations carry a versioned rule ID and a guideline citation.
0Autonomous prescriptions. The clinician is the only mover.
