Step 4 — Project layout

Pause and learn the map — every later step drops files into these folders.

What you will learn

Before you start

Path	You will use it for
`services/`	`ProductService`, `CustomerService`, `OrderService`, `WalletService`
`switches/`	Register `'product'`, `'customer'`, …
`environment/.env`	`APP_NAME`, `JWT_SECRET`, `PORT`
`environment/settings.ini`	`[db]`, `[app_switches]`, `[app_authentications]`
`database/migrations/`	Step 5 — create `products`
`storage/logs/`	Runtime logs when something fails
`public/`	Optional storefront UI in Step 12

curl -s -X POST http://127.0.0.1:8000/api/v1/ \
  -H "Content-Type: application/json" \
  -d '{"service":"product","action":"list"}'

Still returns the two hard-coded products.
