The comprehensive-briefing cache (User.insightsCachedText) is one slot
per account with no record of the language it was written in. Every
reader served whatever was there, so a German-language account whose
nightly warm had written English kept seeing English on the dashboard
lead and the Today briefing. The request path only replaced it once the
row was a day old and the provider answered, which with a provider at
its usage limit was never.
Add User.insightsCachedLocale (migration 0335). Both writers store the
locale they generated in; the timestamp-only refresh on an unchanged
snapshot tags the row too, since the fingerprint covers the generation
locale. Every reset that nulls the text nulls the tag.
The snapshot briefing lift and GET /api/insights/generate treat a tag
that differs from the reader's locale as an empty cache: no prose, no
timestamp, the preparing / no-provider state, and the out-of-band warm
enqueued in the reader's locale through the existing path. The
generator's own short-circuit and the POST short-circuit refuse to call
a foreign-language row fresh. A NULL tag (rows written before this
change) is served as before until the next write tags it. The Today
digest derives from the snapshot and follows.
Covered by unit tests on the lift, the route and the generator, and an
integration test that writes the row through Prisma and reads the
snapshot for a reader in another language.
Adds the cases that were missing everywhere except the FHIR conformance
suite: an empty string clears without taking its siblings down, OTHER
round-trips through the profile and onboarding writes, an unsupported
value is still refused and says which field it is about, the Strain
model scores an unanswered account on neither side, the dashboard bands
give OTHER the neutral fallback, the snapshot payload carries the value
instead of flattening it, and the doctor-report cover omits the row
rather than claiming a value the account never chose.

Sweep every feet + inches pair the fields can offer and every whole-inch
height across the canonical range, asserting the value comes back
unchanged and lands inside the server's window. Assert the metric branch
with toBe so a re-derivation of a stored height cannot slip through.
Render both entry surfaces under each preference: the metric case keeps
the single centimetres box with the canonical guardrails, the imperial
case shows the feet + inches pair seeded from the stored value. Extend
the structural guard so a surface that drops the adapter, hardcodes a
centimetre guardrail, or hardcodes a unit label trips a tripwire.
