- Add apps/api/src/lib/setupGuard.ts exporting isSetupLocked(): Promise<boolean>
(Wave-0 stub returns false; real DB impl ships in Plan 02)
Doc comment enforces D-10: re-evaluate fresh on every call, never module-cache
- Add apps/api/src/routes/setup.ts exporting setupRouter = new Hono()
(empty router; handlers + index.ts mount added in Plan 02)
Doc comment notes pre-auth surface position — before /api/* OIDC chain
