The systolic and diastolic reads each took the ladder's source per day on
their own. Whenever a source held only half of a reading on a day (a deleted
diastolic, an orphaned sample, a sub-floor systolic), the two picks diverged
and the pairing joined one source's systolic to another source's diastolic.
A sub-floor systolic could also claim a day and then contribute nothing,
leaving the day empty although a lower-ranked source had a valid reading.
The source is now picked per day from the systolic rows that pass the floor,
both halves are read from it in one statement, and a pair is only made
within one source, which also covers a reading that straddles midnight.
The blood-pressure branch of /api/measurements/series still read systolic and
diastolic with an unranked findMany, so with a second provider the pairs blended
both sources and a reading present in both showed twice, while the other kinds
already follow the ladder since the dense and raw reads were moved onto the
shared helper.
Each of the two types now reads the ladder-winning source per day through the
same helper. The physiological floors (systolic 40, diastolic 20) and the
five-minute pairing are unchanged.
The rollup tier and sleep resolve every (type, day) to the source the person's
ladder picks before they aggregate. The dense and raw reads of
/api/measurements/series filtered on user and type only, so with a second
provider a day's value blended the two, a reading present in both showed
twice, and the configured ladder had no effect on those charts.
Both reads now take the ladder-winning source per day through the shared
canonicalMeasurementsCte helper, as the other live readers do:
- the day and hour bucket read of the dense kinds (pulse, glucose, HRV, SpO2),
and the stats strip over its rows;
- the generic raw read (weight, body fat, steps, resting heart rate, ...).
The collapse is per day for the hour grain too, as everywhere else. The helper
gains an optional single-type scope so a series scans one metric, not every row
the person has in the window.
Only a type that has a ladder is collapsed. For a type without one (glucose,
body water, bone mass) the helper breaks the tie by source name, which would
silently hide one of two real sources, so those keep every source as before.
A single-source account reads exactly what is stored.
Tests: a real-database test covering the ladder in both directions, the
per-day fallback, a reading mirrored into two sources, the day-bucket, hour-
bucket and raw reads, a type with no ladder and a single-source account. The
route's unit test file reads its fixtures through a small adapter for the new
raw statements, and the dense-read guard drops the exception for the removed
findMany. The OpenAPI description states the rule.
