# M3 Core Module

M3 functionality migrated from the standalone M3 application into Core.

## Database

The module uses Core's PostgreSQL connection by default. Override with `M3_DB_CONNECTION` if M3 data uses another configured PostgreSQL connection.

No DB2, ODBC, IBM i Access, or `zendtech/ibmitoolkit` dependency is required.

Legacy IBM i program-call requests are captured by `PostgresProgramBridge` in `m3_program_requests`, allowing a PostgreSQL-native worker/integration to process them independently of HTTP requests.

## Optional paths

- `M3_LABELS_PATH`
- `M3_CLOSING_ORDERS_PATH`

Both default beneath `storage/app/m3`.

## After replacing the module

```bash
composer dump-autoload
php artisan optimize:clear
php artisan migrate
php artisan route:list --path=m3
```

Health check: `/m3/health`.
