Collisions between <code>Distinct</code> values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely.

Now, when translation would drop data (e.g., invalid label/value), the exporter emits a <code>NewInvalidMetric</code>, and Prometheus scrapes <strong>fail with HTTP 500</strong> by default. To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: <code>promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }</code>.
