Deployment Config Safety Checks

When changing auth, routing, or deployment settings, verify consistency across all related files:

Destination contract

• solution/MyHANAApp/mta.yaml must provide destination srv-api for the AppRouter module.
• solution/MyHANAApp/app/router/xs-app.json must route backend traffic to destination srv-api.

Authentication alignment

• solution/MyHANAApp/package.json should keep cds.requires.auth = xsuaa unless intentionally changed.
• solution/MyHANAApp/xs-security.json should remain aligned with expected XSUAA setup.
• AppRouter routes requiring backend/API access should use authenticationType: xsuaa as intended.

Safe change policy

• Prefer minimal diffs; avoid unrelated formatting changes.
• State cross-file impact in the PR/summary when config changes affect runtime behavior.
• If one file changes and related files are not updated, explicitly document why no sync change is needed.
