 The command does not provision an administrator automatically. Run `npm run provision:admin` once after setting the initial administrator variables in `.env` when admin access is needed. Stop the application processes with `Ctrl+C`; stop the containers separately with `npm run db:down` when they are no longer needed.
 
+For a disposable local database reset, use:
+
+```sh
+npm run db:reset
+npm run provision:admin
+```
+
+Or combine both operations with:
+
+```sh
+npm run db:reset:admin
+```
+
+`db:reset` removes the local PostgreSQL and Redis volumes, recreates healthy containers, and synchronizes the current Drizzle schema with `drizzle-kit push --force`. It is destructive and local-development-only. It does not modify `.env`.
