Epistemic refers to knowledge, justification, and the conditions under which a claim can be regarded as known rather than merely believed. In systems engineering, software development, scientific inquiry, and organizational decision-making, epistemic concerns focus on what information is available, how it is verified, and the degree of confidence that can be placed in it.
An epistemic boundary separates documented facts from assumptions, speculation, folklore, and incomplete information. The quality of a system's epistemic state depends not only on the accuracy of its knowledge, but also on whether that knowledge is accessible, traceable, and reproducible by others.
The term epistemic hygiene describes practices that improve the reliability of shared knowledge. In repository-driven environments, this means replacing undocumented assumptions and institutional memory with explicit, machine-readable artifacts such as specifications, tests, provenance records, decision logs, and structured metadata. Good epistemic hygiene reduces ambiguity, makes reasoning auditable, and allows knowledge to persist beyond any individual contributor.
