Six MEDs grouped per the W5 reconcile brief:
- Sec-MED-1: `hl_onboarding` cookie now `SameSite=Strict` (no
cross-site flow depends on it; sibling `healthlog_session` stays
`Lax` for the Withings OAuth callback).
- Sec-MED-2: `/onboarding` PUBLIC_PATHS match tightened from loose
`startsWith("/onboarding")` to exact path + subroute guard
(`pathname === "/onboarding" || pathname.startsWith("/onboarding/")`).
A future `/onboarding-export` route can no longer inherit the
silent-pass-through. Same guard mirrored on the redirect short-
circuit. Two new proxy tests pin the contract.
- Code-MED-3: lift `berlinDayKey()` from
`src/app/api/analytics/route.ts` to a shared
`src/lib/analytics/berlin-day.ts` and route the targets
sparkline-bucketing through it. The targets route used to bucket
by UTC `YYYY-MM-DD` so a 23:30-Berlin reading on Tuesday landed
in Wednesday's bucket. Four new unit tests pin DST + UTC-midnight
edge cases.
- Code-MED (streaming race): on slow connections SSE `done` fires
before the invalidate-refetch resolves, producing a 200-500ms
duplicate-bubble render. Add a 150ms grace window on the
message-thread that suppresses the persisted twin while the
streaming bubble is still in flight.
- Code-MED-2: drop dead i18n keys `insights.coach.settings` and
`insights.coach.settingsTooltip` (W3 removed the cog; the keys
had zero call sites and would carry confusing legacy if v1.4.23's
prompt-tuning panel picks a different key shape).
- Code-LOW-5: centralise `["user", "dashboardWidgets"]` query key
in `queryKeys.dashboardWidgets()` and migrate the three call
sites (dashboard, insights, settings/dashboard-layout-section).
Same query-key-collision discipline as `queryKeys.analytics()`.
Closes Sec-MED-1, Sec-MED-2, Code-MED-2, Code-MED-3, Code-MED-3
(streaming race), Code-LOW-5.

The post-hydration redirect for users with `onboardingCompletedAt ===
null` caused a brief dashboard flash before the client-side effect
could fire. The redirect now lives in `src/proxy.ts` so it lands on the
first server response.
The proxy runs in the Edge runtime and can't reach Prisma, so the auth
routes (login / passkey-verify / register / password / /api/auth/me)
mirror the DB `onboardingCompletedAt` column into a non-httpOnly
`hl_onboarding` cookie. The cookie is a UX hint, not a security
signal — a user editing it locally only skips the dashboard flash;
they still can't bypass any server check. `/api/onboarding/complete`
clears the cookie so the next navigation drops the redirect
immediately, and `destroySession` + expired-session purge wipe it
alongside the session cookie.
The e2e onboarding-flicker spec can return to testing the actual
incomplete-onboarding case: the proxy reads the cookie (absent for
the fully-onboarded storage-state user), not the mocked `/api/auth/me`
response, so the test now sets `onboardingCompletedAt: null` honestly
instead of pinning it to a non-null value as a workaround.
