            `/` as `%2F`. The tag is matched exactly as encoded, including
            leading, trailing, and consecutive slashes, which are preserved and
            not collapsed (for example, the tag `/services/payments-api` is
            referenced as `%2Fservices%2Fpayments-api`). Tags containing slashes
            are supported via the API but not in the Cortex UI; this difference
            is expected.
