+
+Role:
+- own application-facing infrastructure base units
+- define environment-neutral app workload, service, config reference, secret reference, storage, network policy, probe, and resource shapes
+- organize many services by domain/service path directly under `k8s/base/app/<domain>/`
+
+Current structure:
+- domains sit directly under `k8s/base/app/` (`identity/`, `storage/`, `test/`)
+- inside each domain, separate by workload role (`stateful/`, `stateless/`)
+- example: `identity/auth/stateful/identity-postgres/`, `identity/auth/stateless/auth-server/`
+
+Allowed:
+- Kustomize base edits for application units
+- Deployment / StatefulSet / Job / CronJob base resources
+- Service / NetworkPolicy / PDB / HPA base resources
+- ConfigMap / Secret reference wiring without secret values
+- probe / resource / PVC / StorageClass reference shape
+- component-specific manifests aligned with standards
+
+Forbidden:
+- environment-specific values that belong in `k8s/overlays/<env>`
+- editing packaged K3s component manifests directly
+- treating server-local manifests as source of truth
+- embedding production secret values in Git
+- generating opaque YAML via script as the primary ownership path
+- merging unrelated app rollout + migration + cluster upgrade into one hidden change
+
+Read first:
+- `/docs/standards/infra/architecture-environments.md`
+- `/docs/standards/infra/kustomize.md`

+- `/docs/standards/infra/security-hardening.md`
+- `/docs/standards/infra/observability-health.md`
+- `/docs/standards/infra/db-and-migration.md`
+
+Component-specific routing:
+- paths containing `keycloak` -> `/docs/standards/infra/keycloak.md`
+- paths containing `vault` -> `/docs/standards/infra/vault.md`
+- paths containing `minio` -> `/docs/standards/infra/minio.md`
+- paths containing `flyway` or migration jobs -> `/docs/standards/infra/flyway.md`
+
+Examples:
+- `/docs/examples/infra/kustomize.md`
+- `/docs/examples/infra/config-and-secrets.md`
+- `/docs/examples/infra/workload-selection.md`
+- `/docs/examples/infra/storage-pvc.md`

+- `/docs/examples/infra/keycloak.md`
+- `/docs/examples/infra/vault.md`
+- `/docs/examples/infra/minio.md`
+- `/docs/examples/infra/flyway.md`
+
+Rules:
+- base must stay environment-neutral
+- app services default to `ClusterIP`
+- public exposure must be explicit and added through overlays/ingress policy
+- health/metrics/admin endpoints stay non-public by default
+- DB migration must stay separate from app startup
+- stateful workloads must have explicit storage and restore reasoning
+- domain/unit nesting should make ownership clear for large service counts

+# 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/`.
