 - **Server modules** in `lib/server/` (db, session, mail, rate limiting, etc.).
 - **Create flow:** **Anonymous** users mirror in-progress state to **`create-flow-anonymous`** in `localStorage`; **Exit** opens the save-progress magic-link modal; after verify, [`PostLoginDraftTransfer`](app/(app)/create/PostLoginDraftTransfer.tsx) can **PUT** `/api/drafts/me` when **`NEXT_PUBLIC_ENABLE_BACKEND_SYNC=true`**. **Signed-in** users get a **fresh** in-memory session per “Create rule” entry, but with sync on the layout may **hydrate** from **`GET /api/drafts/me`** via [`SignedInDraftHydration`](app/(app)/create/SignedInDraftHydration.tsx); **Save & Exit** (from `community-structure` onward) **PUT**s when sync is on. **Log in** from the marketing header uses the global modal ([`AuthModalProvider`](app/contexts/AuthModalContext.tsx)); **`/login`** remains for verify errors and deep links. **Step order and URLs:** [`docs/create-flow.md`](docs/create-flow.md) and [`app/(app)/create/utils/flowSteps.ts`](app/(app)/create/utils/flowSteps.ts).
 - **Web vitals** [`app/api/web-vitals/route.ts`](app/api/web-vitals/route.ts): **production default** is **`external`** (structured logs; no `.next` writes). **`local`** file-based mode remains for development (`WEB_VITALS_STORAGE`).
-- **CI:** [`.gitea/workflows/ci.yaml`](.gitea/workflows/ci.yaml) (build, test, lint, `prisma validate`); no in-repo production deploy definition.
+- **Pre-merge checks:** run locally (see [docs/testing-guide.md](../testing-guide.md) § *Running tests*; [CONTRIBUTING.md](../CONTRIBUTING.md) pull request workflow). No in-repo remote CI workflow; production deploy is out of band ([ops-backend-deploy.md](ops-backend-deploy.md)).
