One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
The reference-range classifier assumed bands[0] was always the
normal/target band, so any metric whose first band is abnormal was
placed wrong: a healthy BMI 22 read as just outside the reference and
an underweight BMI 17 read as inside; pulse pressure had the same flaw
(Narrow is its first band). The same classifier drives the in-app
four-state explainer, so both surfaces were affected.
Mark the population-normal band explicitly with a `normal: true` flag
on every metric, add `normalBandIndex`, and place values by distance
from the marked band rather than from index 0. `headlineBandText` now
renders the marked band, so BMI grounds against 18.5-24.9 kg/m2.
Exclude daily steps from the Coach grounding: it is fed the intra-day
mean of the step rows, which averages a multi-row day down and can
misplace it below the 8,000 floor. Grounding it on a per-day sum is the
correct fix and is left as a follow-up; until then drop the line rather
than ship a wrong placement.
Extend the classifier and grounding tests for BMI 17/22/27, a pulse
pressure case, the normal-band-not-at-index-0 contract, and that steps
is not grounded.
Surface the population reference bands behind the metrics a Coach turn
carries as a compact, citation-aware grounding block appended after the
SNAPSHOT. For each present metric the block states the headline band, its
source (blood pressure on the ESH 2023 line, US/ESC framings as context
only), and where the user's value sits via the shared four-state
placement contract.
Framed strictly as general guidance: the block opens and closes with a
not-a-diagnosis caveat, never overrides the existing refusal/dose/drug-
level safety discipline, and carries no commercial brand name. Glucose
respects the diabetes opt-in — the tighter ADA management goal only when
the user has declared it, otherwise the general non-diabetic band.
The block is deterministic and inspectable: built purely from the
reference-range backbone over the same scalars the snapshot already
surfaces, so it can never cite a value or band the snapshot does not
carry.
