Use when a public review needs an on-voice reply, when you need to earn more reviews legally, or when an aggregate rating is slipping across Google Business Profile, Trustpilot, the App Store or Google Play — including deciding reply versus flag, getting an unfair one-star removed rather than merely answered, and wiring programmatic replies. NOT a private support ticket against an SLA (that is `customer-support`), NOT churn, NPS or save plays (that is `retention`).
