A statement that says "today", or compares today against a baseline,
now only rests on a reading taken on the current calendar day in the
reader's zone. Yesterday morning's pulse read at nine in the evening
was narrated as today's: the signals of the day accepted any reading
from the last two weeks, and the Today overview, the coincident
deviation flag and the health status counted yesterday as current.
- computeSignalsOfDay drops a metric with no reading today, so the
briefing prompt and its content hash never see a stale value as the
day's; the prompt says so in both languages.
- The digest serves no cached briefing written on an earlier day and
drops a reading-backed signal whose metric was not measured today,
so the web hero, the iOS topSignal and the morning push agree.
- The Today overview's vitals line and deterministic lead, the
coincident flag and the health status deviations use the new
isFromToday rule (calendar day, not elapsed hours).
Signal deltas now carry each metric's display precision: the prompt
input is rounded (whole bpm and mmHg, one decimal of kg), and the
delta string under the hero lead is re-read at that precision in the
reader's locale ("+34 bpm", not "+33,72 bpm").
The daily briefing serialised the aggregated feature set as computed:
weight, grip strength and the weight target in kilograms, waist in
centimetres, glucose and the signals of the day in mg/dL (the glucose
signal carried no unit at all), workout distances in kilometres. A
reader on pounds or mmol/L got a briefing in units they do not use.
One step now converts the feature set after all canonical arithmetic,
on both the nightly and the on-demand path: absolute values through the
full transform, differences and slopes through the factor alone, every
converted block labelled, workout distances under unit-neutral keys.
The prompt, the stored fingerprint and the grounding check all read the
converted set, so a unit switch moves the fingerprint and the grounding
check compares the reply against the figures the model was shown. The
weight target sentence, the comparison block and the GLP-1 plateau
context quote weight in the reader's unit; the comparison block also
labelled sleep as hours while carrying minutes.
A unit switch now also re-warms a cached briefing alongside the status
notes and narratives.
