HealthPatio

Wellbeing data with its context intact.

An initial direction for connecting wellbeing observations with consent, provenance and control. HealthPatio would help products use the data a person chooses to share, for a clearly defined purpose.

Mapping rule

Keep the logged quantity and unit.

Overlap: keep both sources

Why this decision?

Two connections report 25,200 s for the same subject and interval. Keep two records and an overlap reference; do not add their durations.

One subject, one selected local day

Why this decision?

Sleep, workout and nutrition keep distinct records. The link uses subject-17 and the Europe/Paris day window, not matching names or a claim that one caused another.

One fictional subject and local day. Unit conversion is an explicit proposed Patio recipe, not an inferred provider capability or health recommendation.

ContractSpec supplies the cited building blocks. This end-to-end recipe is a proposed Patio composition; its fixture decisions do not run those services.

Sleep, workout and nutrition provider record fields Required health observation fields and strict validation Replay, cross-source overlap and correction decisions Subject-bound goals and recipient-specific projections Explicit mapping and coercion rules Field-scoped authorization before projection

A local simulation. No account is connected and no message, publication or deployment is sent.
