The route answered sleep minutes, steps, active energy, resting heart rate,
heart-rate variability and an illness day-log with its symptom keys, and it
declared `mind`. A delegate given only the mind section could walk arbitrary
dates through the one URL and read two sections the owner had declined to
share; no mood entry had to exist for any of those dates.
`record` is the convention for a read that crosses sections, and a scoped
grant never reaches one, so the scoped delegate loses the linked block rather
than receiving a filtered day. A block that silently dropped the sections a
grant does not cover would show a day that looks empty where the truth is that
it is none of the reader's business.
The reason is written at the declaration and in the frozen surface entry,
whose previous justification held only for whole-record grants.
- one resolver reads the day's figures from the modules that own them; nothing
is copied onto the mood row, so correcting a sleep session corrects it here
in the same moment
- absence answers { present: false } rather than zero, because a night nobody
recorded and a night of no sleep are different facts
- a module switched off blanks its whole block instead of filtering down to an
empty one
- keyed by the local day so the capture sheet can ask before an entry exists
