+# 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/<unit>/<domain>/<workload-kind>/<workload>/
+```
+
+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/`.
