Three related fixes:
- Cookie secure flag now tracks AUTH_URL scheme (https → Secure),
not NODE_ENV — staging over HTTPS with NODE_ENV!=production used
to ship Set-Cookie without Secure. Cookie name gains __Host-
prefix when Secure is on.
- jwt() callback no longer swallows session-registry write failures;
concurrent-session cap is now fail-closed.
- Session callback no longer copies token.sid onto session.user.jti.
The tRPC route handler reads the JTI directly from the encrypted
JWT via getToken() so it stays server-side.

Prevent user-enumeration via login-response timing and audit-log content.
All failing branches now run argon2.verify against a precomputed dummy
hash (discarding the result), and emit a single "Login failed" audit
summary. Detailed reason stays in the server-only pino logger.

#41 (critical): Replace plain Error throws in authorize() with CredentialsSignin
subclasses (MfaRequiredError / MfaRequiredSetupError / InvalidTotpError).
Auth.js v5 forwards CredentialsSignin.code to the client via SignInResponse.code;
plain throws become CallbackRouteError and the message is never visible.
Signin page now checks result.code ?? result.error for exact code matching.
#38: MfaPromptBanner converted to fully client-side component via
trpc.user.getMfaStatus.useQuery() — disappears immediately after MFA enable
without requiring page reload. Snooze key remains userId-scoped via useSession().
Server-side prisma.user.findUnique call removed from (app)/layout.tsx.
#40: NEXTAUTH_URL default fallback removed from docker-compose.yml.
The variable is now required (:?) — docker compose up fails with a descriptive
error if the value is missing, preventing silent localhost redirect bugs.
Tests: auth.test.ts (5), MfaPromptBanner.test.ts (7), reset-password.test.ts (6)
All new tests green. pnpm --filter @capakraken/web exec tsc --noEmit clean.
