Every write has gone to insights_cached_text_encrypted since 0411, and
the boot-time free-text backfill sealed the rows written before it.
Migration 0430 drops insights_cached_text and the backfill index that
served it. A host that skipped the intervening releases loses only a
cache of model output; the next warm writes a fresh, sealed payload.
The cipher module now reads and writes the sealed column only, the
backfill job loses its insights step, and consent withdrawal, the wipe
plan, the backup plan and the session projection follow the schema.
Backups never carried the column, and restore ignores unknown account
settings; a round-trip test now proves an old backup naming the field
still restores cleanly. The access guard pins exact counts for where
the sealed name may appear. Fixtures, the demo seed and the demo
migration script seed the sealed column instead of plaintext.
The today check now reads briefingGeneratedAt from the cached payload
and treats a payload without it as not from today. The integration
and e2e fixtures that seed a fresh briefing write it, as every real
generation does.
Three files walk the AI state matrix through the real handlers: every
data route answers the baseline's data under each state, and an ECG
upload is stored with AI off; mixed reads null the model text, name the
reason and enqueue nothing, and the dashboard hides a cached briefing on
the next read after a switch flip; the briefing and Coach actions refuse
with the exact code, capability and reason before any provider or cache
write. Existing files that seeded provider-less accounts now give them a
provider where the briefing or the Coach is under test, and the sharing
front door marks the digest by a due checkup, since model text is not
served inside somebody else's record.

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.
