Overview

Verifies the Rails cache is reachable via a read-only probe.

We deliberately don’t write — a flapping cache shouldn’t corrupt host app cache state. If the read raises (connection refused, decoding error, etc.), the check fails. Non-critical by default: a degraded cache shouldn’t pull the app out of rotation.
