+# SG-200 - Connection Testing and Health Diagnostics
+
+Groups 197-200 add one genuine, validated and recoverable embedded Settings
+workspace for credentialed-test plans and explicit health observations without
+running connections in the configuration-free product.
+
+## Approved evidence set
+
+1. `01-ordinary-empty-connection-health.png` - genuine empty ordinary state with zero connections run.
+2. `02-required-diagnostic-validation.png` - required capability and owner validation without mutation.
+3. `03-secret-diagnostic-rejection.png` - invalid reference value and secret-like notes rejected visibly.
+4. `04-isolated-demo-health-summary.png` - labelled isolated diagnostic summary using fictional metadata.
+5. `05-isolated-demo-health-records.png` - fictional ready and blocked records with explicit manual observations.
+6. `06-test-validation.png` - eight focused tests and 731-test regression result.
+7. `07-release-build-validation.png` - clean Desktop and Android Release builds plus runtime inspection.
+8. `08-safety-supply-chain-validation.png` - dependency, hygiene, no-connection and evidence-integrity checks.
+
+Pack 2 is complete. Five LifeOS images and three Notepad validation images were
+captured directly from their target window handles and inspected. Ordinary/Home
+was restored, and invalid ordinary and isolated-demo interaction created no
+connection-health file.
