# Ladill Mini — deploy & cutover runbook

Standalone app for **trader payment QRs** at `mini.ladill.com` — static scan-to-pay
codes with amount entry, no catalog. Takings settle into the one platform
UserWallet (5% 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 payment codes to this app (see
`MiniQrForwarder` on the monolith); grant the platform DB user read access:

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

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

## 0. Prerequisites

| Secret | Where |
|---|---|
| `LADILL_SSO_CLIENT_ID` / `LADILL_SSO_CLIENT_SECRET` | `passport:client` on platform |
| `BILLING_API_KEY_MINI` | platform `.env` + this app |
| `IDENTITY_API_KEY_MINI` | platform `.env` + this app |
| `PLATFORM_DB_*` | read `ladilldb.platform_settings` (Paystack keys from admin → Billing) |

Paystack credentials are **not** duplicated in this app’s `.env`. They are
configured in the platform admin panel (`/admin/settings` → Billing) and read
at runtime from `platform_settings` via the `platform` DB connection.
Grant the app DB user `SELECT` on `ladilldb.platform_settings` only.

## 1. Gitea repo + CI

1. Repo: **ladill-mini** (create on Gitea)
2. Push to `main` triggers `.gitea/workflows/deploy.yml`.
3. App root: `/var/www/ladill-mini`

## 2. Server app-slot + database

```bash
sudo install -d -o deploy -g www-data /var/www/ladill-mini
sudo install -d -o deploy -g www-data /var/www/ladill-mini/{releases,shared}
sudo mysql -e "CREATE DATABASE ladill_mini CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"
sudo mysql -e "CREATE USER 'ladill_mini'@'127.0.0.1' IDENTIFIED BY '<pw>';"
sudo mysql -e "GRANT ALL ON ladill_mini.* TO 'ladill_mini'@'127.0.0.1'; FLUSH PRIVILEGES;"
sudo mysql -e "GRANT SELECT ON ladilldb.platform_settings TO 'ladill_mini'@'127.0.0.1'; FLUSH PRIVILEGES;"
```

The Gitea deploy runner acts as `deploy`. The app root and `current` symlink must be
owned by `deploy` (not root), or the release switch step will fail with
`sudo: a password is required`.

## 3. Register OIDC client (platform)

```bash
php artisan passport:client \
  --name="Ladill Mini" \
  --redirect_uri="https://mini.ladill.com/sso/callback"
```

## 4. Platform integration

```env
BILLING_API_KEY_MINI=<same>
IDENTITY_API_KEY_MINI=<same>
RP_MINI_FRONTCHANNEL_LOGOUT=https://mini.ladill.com/sso/logout-frontchannel
LADILL_MINI_APP_URL=https://mini.ladill.com
```

Add `mini` to `config/pdns.php` service subdomains (done in monolith).

## 5. nginx + TLS

```bash
sudo deployment/setup-service-subdomain-nginx.sh mini --app /var/www/ladill-mini/current
```

## 6. First deploy

```bash
cd /var/www/ladill-mini/current
php artisan migrate --force
php artisan config:cache route:cache view:cache
```

## 7. Verify

- SSO login at `mini.ladill.com`
- Create a payment QR, download PNG
- Scan `/q/<code>`, pay test amount, confirm wallet credit (net of 5%)
- Withdraw from `account.ladill.com/wallet`

## Product IA (blueprint)

- **Overview** — today's takings, payment count, wallet balance
- **My Payment QR** — print/display static QRs (one per till/branch)
- **Payments** — incoming payment feed
- **Payouts** — wallet-first settlement, withdraw to bank/MoMo
- **Settings** — business branding (no Developers by default)
