# Ladill Merchant — deploy & cutover runbook

Standalone app for **shop, menu & booking storefronts** at `merchant.ladill.com` — QR
storefronts with catalog checkout. Sales settle into the one platform UserWallet
(15% fee), then withdraw via `account.ladill.com`.

Public scans stay at `ladill.com/q/<code>` (blueprint decision — printed codes
never migrate). The platform host forwards shop/menu/booking codes to this app (see
`MerchantQrForwarder` on the monolith); grant the platform DB user read access:

```bash
sudo mysql -e "GRANT SELECT ON ladill_merchant.qr_codes TO 'ladilldb'@'127.0.0.1'; FLUSH PRIVILEGES;"
```

Set `MERCHANT_DB_*` on the platform `.env` if the lookup user differs from the
main app DB user.
