+"""Read-only diagnostic: print the structure of `medical-chatbot-app`'s
+inline `spec.source.helm.values` on the live ArgoCD Application, with any
+line that looks like it holds a credential redacted. Also prints per-resource
+health from the resource tree, so a Degraded app health can be traced to the
+specific Deployment/Pod causing it.
+
+Never mutates anything. Exists to let us see the real inline-values layout
+and live resource health before writing a script that edits the Application
+(see the note in infra/argocd/applications/medical-chatbot-app.yaml about
+what stays inline).
+
+Required env: ARGOCD_PRACTICE_URL, ARGOCD_PRACTICE_PASSWORD.
