ensureDbCompatibility ran ALTER TABLE / CREATE TABLE IF NOT EXISTS on the
login, register, token and session paths, mirroring columns every
migration under prisma/migrations already creates. The entrypoint applies
those migrations before the server listens and stops the boot when one
fails, so the mirror never had work to do, and DDL on a request path
needs the table's owner: a connection that may only read and write rows
fails every login on it. Drop the module, its call sites and the mocks
that stubbed it out.
132 route handlers spelled out safeJson, safeParse and the 422 refusal by
hand in one of six shapes. Each block becomes one parseJsonBody call with
the same size cap, wide-event action, issue count, error code, message and
status it had, so every response is the one it was. The comments inside
the replaced refusal blocks go with them.
A ratchet (route-body-parse-ratchet) counts the route files that still call
safeJson themselves; the count may only fall.
Data never depends on AI. The Insights data reads no longer ask an AI
switch or the `insights` module (now only the AI analysis opt-out): ECG
list, detail and upload, rhythm events, derived scores, rule cards,
correlations and patterns, the baseline strip, health status, intraday
pulse, and the Today digest with its dismiss. Breathing screening moves
to the sleep module and lab changes to the labs module. Stored Coach
facts, conversations, message ratings and the seen stamp stay readable
and erasable while the Coach is unavailable. Cards now say
`provider: "rules"`.
Reads that mix data with model text answer 200, null the model text
and publish an `ai` state from the capability resolver, without warming
anything: comprehensive (`ai.briefing`, `ai.statusText`, `hasProvider`
from the presence probe), the derived assessment override, the period
narrative, nudge status, the seeded opener, about-me questions, the
workout paragraph, the pregenerate warm (`queued: false`), the Today
digest (lead, reaction line, check-in) and the dashboard briefing,
which is now applied per read after the snapshot cache. Hiding the
Coach no longer hides the briefing.
`insights/generate` GET and POST ask the `briefing` capability and
`insights/chat` POST the `coach` capability, with the typed refusal
envelope; a missing provider keeps the chat's `coach.provider.none`
frame and adds `reason`. The /coach page, the MCP ECG and intraday
tools and `aiAvailable` on the provider route follow the same answer.
An inventory of AI and data routes replaces the Coach gate inventory:
every route that asks a capability names it, and no data route asks.
