 Clearity is a workspace, client, and contract management platform for managed office operations. It tracks clients, contacts, addresses, rooms, services, bookings, contracts, invoices, and workspace admins from a SvelteKit dashboard.

 Required:
 
-- `DATABASE_URL`: SQLite/libSQL connection URL for local development. Use `file:local.db`.
 - `ORIGIN`: Public app origin, for example `http://localhost:5173` locally or `https://clearity.example.com` in production.
 - `BETTER_AUTH_SECRET`: Secret used by Better Auth.
+- Cloudflare D1 binding `DB`, configured in `wrangler.jsonc`.
 
-Production also requires the Cloudflare D1 binding named `DB`, configured in `wrangler.jsonc`. Do not set `DATABASE_URL` in production unless you intentionally want to use a hosted libSQL database instead of D1.
+Local development uses the same `DB` binding shape as production. SvelteKit's Cloudflare adapter populates `platform.env.DB` from `wrangler.jsonc` during dev and preview, and Wrangler stores local D1 data in its local state directory.
 
 ## Database
 
 The application schema lives in `src/lib/server/db`. Drizzle migration files live in `drizzle`.
 
-Runtime database selection is:
+Clearity always uses Drizzle's Cloudflare D1 driver through the `DB` binding. Apply migrations to the local D1 database before starting the app:
-
-- If `DATABASE_URL` is set, Clearity uses the libSQL driver.
-- If `DATABASE_URL` is not set and the Cloudflare `DB` binding exists, Clearity uses Drizzle's Cloudflare D1 driver.
-
-The fastest local database is a SQLite file:
 
 ```sh
-DATABASE_URL=file:local.db pnpm db:migrate
+pnpm db:migrate:local
 ```
 
 For schema changes:
 
 ```sh
 pnpm db:generate
-DATABASE_URL=file:local.db pnpm db:migrate
+pnpm db:migrate:local
-```
-
-To test against Wrangler's local D1 simulator instead, leave `DATABASE_URL` unset, apply migrations locally, and run the app through the Cloudflare Worker build:
-
-```sh
-pnpm build
-pnpm wrangler d1 migrations apply clearity-production --local
-pnpm wrangler dev
 ```
