One reviewed meaning per metric

Canonical Health Data Model

Every observation — from a wearable, a laboratory, a habitat sensor or a questionnaire — becomes the same structured envelope. That shared meaning is what makes personal baselines and explainable findings possible.

Why it matters for long-duration spaceflight

  • Comparing values across devices requires one unit and one definition per metric.
  • Provenance and quality must travel with every value so reviewers can trust or discount it.
  • Research-only measures must be clearly separated from operational ones.

How The Mitochondria addresses it

  • A reviewed metric registry derived from the v1.1 biomarker matrix defines code, unit and classification.
  • The observation envelope carries subject, mission, source provenance, timestamp, sampling, quality and sync state.
  • High-frequency signals such as ECG use a separate raw-series chunk contract.

Technical explanation

Deterministic serialization

Observations round-trip through deterministic serialization so the same input always produces the same stored record.

Interchange-ready

Optional external coding metadata allows later FHIR-compatible exchange without making FHIR the internal model.

Implementation status and limitations

  • Implemented in repository

    The registry, ingestion pipeline, unit normalization and serialization are implemented and tested.

  • Not clinically or flight validated

    Biomarker Matrix v1.1 is a team scientific implementation review, not clinical validation.

Known limitations

  • Missing or poor-quality safety-relevant values are never silently imputed.
  • Independent scientific review remains pending and is not marked approved.

The Mitochondria is human decision support. It does not diagnose, prescribe treatment or replace qualified medical judgment.
