+This directory is organized into the following top-level directories:
+
+- **`base/`** — Common resources (deployments, services, CRDs, RBAC) shared across all environments
+- **`overlays/`** — Environment-specific Kustomize overlays (e.g. `production`, `e2e`, `kind`, `kind-local`, `local-dev`)
+- **`observability/`** — Monitoring and observability resources

 ✅ **Clear Differences**: Overlays show exactly what's unique per environment
 ✅ **Type-Safe**: Kustomize validates patches against base resources
 
-## Migration Notes
-
-This structure replaces the previous duplicated manifests:
-- ~~`components/manifests/*.yaml`~~ → `base/` + `overlays/production/`
-- ~~`e2e/manifests/*.yaml`~~ → `overlays/e2e/`
-- ~~`components/scripts/local-dev/manifests/*.yaml`~~ → `overlays/local-dev/`
-
-Old manifest directories have been preserved for reference but are no longer used by deployment scripts.
