Add the data-value features to the insights category pages on top of the
density pass:
- Stat strip: lead each metric page with min / max / median / mean,
read from the already-fetched analytics summaries slice (no new
network). Median is now computed in both summary producers — exact in
the live path, a windowed PERCENTILE_CONT in the rollup-tier slim
slice. The thin HealthKit pages mount it too for parity; no AI
assessment is added there.
- Range band: shade an Apple-Health-style min-max area around the daily
mean line where the data supports it (non-cumulative metrics). The
daily-aggregate read now emits per-day min / max from the rollup
buckets; the band rides the existing target-range toggle.
- All readings: a dedicated per-metric subpage at /insights/values/<type>
reusing the measurement list pinned to one type (pagination + inline
edit/delete). A clear entry button mounts at the foot of each
category page.
- Diversity nudge: a gentle hint when a metric's readings cluster on one
weekday or time of day, computed from a bounded, cached timestamp
window — non-blocking, self-gating.
All new reads stay cache-friendly and off the navigation path.
The v1.7.2 default-ON snapshot flag makes the dashboard read every tile
from GET /api/dashboard/snapshot; the e2e build sets no opt-out var, so
the specs that only mocked the legacy cells hit the real route, got
empty summaries for the zero-measurement seed user, and timed out the
tile/chart assertions.
Add a shared, correctly-typed mock helper and wire it into the five
tile-asserting specs alongside the existing legacy mocks (kept to
protect the reversible path).
