Confirm scope, user impact, and reproduction
Info

4
Validate prerequisites and application/session state

5
Run safe diagnostics from the Commands section
Info
Recommended validation or troubleshooting step
Use the command snippets below to collect non-destructive diagnostics. Capture output in the ticket when escalation may be required. Avoid deleting profiles, cached credentials, or managed app data unless the runbook or admin approval explicitly allows it.

Apply safe remediation steps

Review carefully before proceeding
