Their relevance depends on the deployment. The public architecture does not assume that one source proves every class of physical event. ## Detectability over impossible promises No cyber-physical system can guarantee that fraud never occurs. PoWV is designed to make manipulation, inconsistency, substitution, and discontinuity more detectable and reviewable. ## Independent review An authorized party should be able to evaluate the basis of an assurance outcome without relying solely on the operator who originated the claim. ## Modularity and interoperability Industrial environments evolve slowly and contain legacy infrastructure. PoWV is designed to preserve stable assurance objectives while allowing deployment-specific adapters and systems to vary. ## Least necessary disclosure A reviewer should receive the evidence and context necessary for an authorized decision, while sensitive operational, personal, commercial, and implementation data remain controlled. ## Explicit maturity Research demonstrations, controlled pilots, production deployments, and certified systems are different maturity states and must not be presented as equivalent. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://powv-protocol.gitbook.io/powv-protocol-docs/architecture/design-principles.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
