As long as you intend to perform the validation inside the fact implementation, the fact can keep and use its own cache somewhere on the system. Alternatively, the master stores the most recent set of facts provided by each node, and it can be accessed via the REST API <https://docs.puppetlabs.com/guides/rest_api.html#facts>. You could conceivably use that as a fact cache. Overall, however, it is probably a poor idea to compute or rely on node facts that reflect the dynamic state of the system, as opposed to its (semi-) stable configuration.
