Extend the daily-mean consolidation to cover the high-frequency
gait/mobility metrics that previously mapped to no consolidation set and
piled up at sampling granularity: walking asymmetry, walking
double-support, walking steadiness, and walking heart-rate average. The
correct daily reduction for these is the mean, matching the Health-app
display; all four stay disjoint from the cumulative (sum) set.
Fold the daily-mean drain onto the existing nightly cumulative-drain tick
so new high-frequency spot samples no longer accumulate raw between worker
reboots. The two passes share one concurrency-1 cron, keeping the
maintenance window a single sequential walk. Boot-time discovery stays as
the back-fill for accounts that accumulated raw rows before this shipped.
Recompute the affected day's rollup bucket after the consolidation
commits, the same way the ingest path does, so a rollup-covered read
reflects the single consolidated row rather than a stale mean derived from
the now soft-deleted per-sample rows.
Regular heart-rate / pulse stays raw: it is a discrete clinical reading
and feeds correlation and scatter analytics. No schema change.
