RMP.6:5.2 - A blocked reproduction is not a contrary result

An analyst receives a published model claim and code, but the data needed to execute its reported analysis are not accessible under the available rights. The analyst cannot obtain the target computation.

The result is an access-limited attempt, not a reproduction with a discrepant output and not evidence that the underlying claim is false. State the unavailable comparison and what the supplied code or description can still support. If a permitted data arrangement later becomes available, assess and perform the actual reproduction under its criterion.

If that later computation returns a different value, preserve the distinction: now there is an observed discrepancy to examine. Check the target, inputs, environment and justified tolerance before deciding which part of the reported claim changes.
