The seven documented statuses are four kinds of thing, so they get four
rulings instead of one.
Taken and Skipped state a decision about a dose and each maps onto something
already recorded here — a row with a take time, and a row marked skipped. That
second mapping was checked rather than assumed: skipped is documented as a
deliberate skip and held apart from autoMissed, which is the marker for a dose
nobody ever acted on, and the compliance re-fold counts a skipped slot in its
own column and never as taken. So a deliberate skip arrives as one.
Not Interacted, Not Logged and Unspecified are absences rather than
statements. Written as taken they would invent a dose; written as skipped they
would invent a decision, because not answering a notification is not choosing
not to take something; written as pending they would put outstanding doses
from years ago in front of someone today. Snoozed describes what happened to a
reminder. Notification Not Sent is about the software. None of the five
becomes a row.
All five are refused, but each under its own name, because "the file says
nothing about this dose" and "this row is about a reminder" are different
things and a person acts on them differently. Three reasons where there was
one, each with its own sentence in six locales.
An inactive medication's history imports and the medication stays inactive.
Preserving what happened and putting a medication back on the active list are
two acts, and only the first belongs to an import.
The fixture is the export a self-hoster attached, de-identified as it
arrived: 3,395 rows, sixteen medications, three and a half years, two UTC
offsets, three statuses, two units, blank cells in four columns. A
hand-built fixture would have carried one status and one offset and proved
nothing about the file that prompted the work.
The integration pass runs it through the real derivation into a real
Postgres, because the claim is about rows: 3,387 land, 8 are refused because
the file records no decision about them, and imported plus refused equals
every row read. 2,799 of the doses were taken after they were due, which is
the fact that survives only because the scheduled slot and the take are two
columns.
Structural cover so the verdicts cannot rot: every column of both shapes has
exactly one ruling, and every parse-time refusal is spelled the same as a job
skip reason — a reason that exists in only one vocabulary renders as "reason
not recorded", which is a refusal nobody can act on.
