Replace the fixed three-beat assessment skeleton with a menu of moves the
model orders freely, and reframe the daily briefing from per-signal
enumeration to a verdict-first read that weaves the few salient signals into
one associative story. Score cards now name both the helped and the hurt
contributors, translate the band into a forward read for the day, and close
on one grounded nudge; the deterministic fallback gains the same band-meaning
sentence so provider-less and demo accounts read as well.
Add a hash-seeded opener-archetype rotation (deterministic, testable) so
consecutive cards and days no longer open the same way, a day-rotated sampling
seed for the period narrative in place of the fixed reference seed, and a
shared paragraph formatting contract. Add a score-number grounding gate and
extend the briefing grounding allow-set to the glucose, labs, preventive-care
and workout aggregate blocks so real figures can be cited without opening the
gate. Gate the daily score warm on an input fingerprint so a quiet day skips
the model call.
Replace the v1.4.20 "conversational summariser" persona with a partner
who sits alongside the user — warm, curious, conservative, with seven
numbered ground rules that prefer invitation over refusal when data is
missing and reserve specific numbers for a structured evidence block
at the end of each reply. The day-level timeline section from v1.4.21
stays verbatim so weekday questions still resolve cleanly. Bumps the
shared PROMPT_VERSION from 4.20.2 to 4.22.0 and broadens existing
schema tests off the 4.20.x pin onto the 4.x train.

Extend `aiInsightResponseSchema` with an optional, nullable
`trendAnnotations: { bp?, weight?, mood? }` block — one short
sentence per metric, capped at 200 characters. Each field is
independently optional so the model emits only the metrics it can
ground in the snapshot.
Insight-generator prompt picks up GROUND RULE 9 (EN + DE):
single-sentence, observational, ≤ 200 chars, banned causal
phrases enumerated. PROMPT_VERSION bumps 4.20.0 → 4.20.1 to
signal the format change so cached payloads from B1 still parse
through the `.nullable().optional()` field.
13 tests cover the boundary (200 chars), the empty-string
rejection, the legacy-payload round-trip, and the EN/DE prompt
rule presence.
