+      - The response states that `az resource show` provides resource configuration and provisioning metadata and cannot establish Azure Resource Health or workload health.
+      - The response identifies the current `Microsoft.ResourceHealth/availabilityStatuses/current` lookup, such as through `az rest`, and does not run it in this evidence-only scenario.
+      - The response notes that the lookup requires `Microsoft.ResourceHealth/AvailabilityStatuses/current/read` and applies only to supported resource types.
+      - 'The response distinguishes Azure platform availability states from application, guest, dependency, and end-to-end health; it does not infer `Available` or healthy from `provisioningState: Succeeded`.'

+`az resource show` returns resource configuration and provisioning metadata; it does not query Azure Resource Health and cannot by itself establish that a resource is healthy or `Available`.
+
+The Resource Health request requires Azure authentication and the `Microsoft.ResourceHealth/AvailabilityStatuses/current/read` operation at the applicable scope. It applies only to resource types supported by Azure Resource Health. Interpret `availabilityState` as Azure platform availability evidence (`Available`, `Unavailable`, `Degraded`, or `Unknown`), not as application or workload health. `Available` does not prove the guest, application, dependencies, or user path are healthy, and `Unknown` must not be treated as healthy.
+
+If the resource type is unsupported, the status is unavailable, permission is denied, or the health query fails, report that limitation and leave Resource Health availability unestablished; do not substitute provisioning success or invent a healthy result.
