}Authorizations
A 15-minute token bound to one patient and one enrollment, issued by POST /v1/oauth/token with the
token-exchange grant. Treat it as opaque. When it expires, exchange a fresh assertion; there is no refresh token.

The day, in the patient's time zone.
Body
JSON Merge Patch (RFC 7396) on one day. Values are the day's totals: send the new total, not an increment.
null clears a value. Weight and body measures go here.
