The snapshot builder probed rollup coverage up front to gate the thick
extras phase, then called computeSummariesSlice which re-ran the
identical probeRollupCoverage query. Thread the already-probed map into
the slice as an optional argument so the snapshot's hot path issues the
probe once. The argument is optional with the internal probe as the
fallback, so every other caller is unchanged.

SLEEP_DURATION is stored in minutes, one row per sleep stage per night
(IN_BED / AWAKE / ASLEEP / CORE / DEEP / REM) since the HealthKit
category-sample ingest landed. The value is not cumulative, so reading
the single most-recent row surfaced one stage's minutes — never the
night. The dashboard sleep tile and the sleep series therefore showed a
fragment of the night rather than the night.
Add a shared `summarizeSleepNights` helper that groups the per-stage
rows by the wake-day calendar date in the user's timezone and sums the
asleep stages (CORE + DEEP + REM, plus a legacy bare-duration row),
excluding IN_BED and AWAKE per the AASM convention already used by the
sleep score. Wire it into:
- the dashboard summary tile, which now emits last night's time asleep
in hours with an explicit `unit: "h"` and a per-stage breakdown for a
future detail view;
- the sleep series, which now returns one point per night (time asleep
in hours) plus a top-level `unit` for every kind so clients never
infer the unit;
- the slim summaries slice, so the web dashboard tile and the insights
overview read per-night totals (kept in canonical minutes there; the
web tile converts to hours) — strictly more correct than averaging
across stage rows, and parity with the iOS value.
Default the dashboard snapshot flag to ON (disable with
NEXT_PUBLIC_DASHBOARD_SNAPSHOT=false). The legacy four-cell waterfall
let the mood cache resolve first and pop in ahead of the rest of the
strip; the snapshot path hydrates every tile from one un-gated cell so
the whole strip shares a single completion moment.
Defaulting on rather than gating on === "true" sidesteps the
NEXT_PUBLIC_* build-time-baking trap: the production image and dev/e2e
all exercise the snapshot path without a special build flag. Fully
reversible to the legacy path via the env var. Comment-only sync in
page.tsx; no logic change there.
