# Application Base This package owns the `app` namespace and the contract for application workloads. For large scale, workloads are grouped by unit, domain, workload kind, and workload: ```text base/app/units///// ``` Examples: - `base/app/units/commerce/checkout/services/order-api/` - `base/app/units/commerce/checkout/workers/payment-settlement-worker/` - `base/app/units/identity/auth/schedulers/token-cleanup-scheduler/` - `base/app/units/data/storage/stateful/orders-postgres/` Rules: - The unit folder is the broad ownership boundary for a business unit, platform area, or organization. - The domain folder is the bounded context inside a unit. - The workload-kind folder groups similar operating models inside one domain. - The workload folder is the smallest independently deployable package. - Kubernetes object files stay together inside the workload package. - Shared namespace-level objects go in `shared/`.
