Model Boundaries
DT4H separates computational modeling from clinical authority.
DT4H produces infrastructure-level modeling signals: cohort context, reference-human priors, Twin state, calibration confidence, and runtime evidence. These are not clinical diagnoses.

DT4H OutputsModeling signals
- Cohort fit and population context.
- Reference-human priors and variance ranges.
- Twin initialization and state estimates.
- Calibration confidence and evidence maturity.
- Trajectory and transition signals.
BoundaryNot clinical authority
- Not a diagnosis.
- Not a prescription.
- Not autonomous medical advice.
- Not a substitute for clinician review.
- Not a replacement for regulated validation.

Boundary examples #
Cohort fitContext onlyA cohort signal provides population context; it is not a diagnosis.
ConfidenceModel maturityConfidence describes evidence maturity; it is not medical certainty.
TrajectoryRuntime directionTrajectory reflects modeled direction; it is not deterministic prognosis.
Protocol handoffExecution supportSETPOINT may act on bounded state, but clinical oversight remains separate.
Implementation notes #
Return bounded outputsModel outputs should clearly identify whether they are cohort context, state estimates, confidence, or calibration signals.
Avoid diagnostic wordingUse language such as signal, state, confidence, trajectory, and readiness instead of diagnosis or prescription.
Require review pathsBoundary-sensitive workflows should include clinician, governance, or operator review paths before clinical reliance.
