Method. Controls only (ISM-principles excluded). A content modification requires ASD's native
revision/updated stamp to move (3 prose-only re-renders excluded as format noise). Relocation compares case/spelling-normalised chapter›section›topic paths. Nature = normalised edit distance (editorial <0.05, clarification <0.25, substantive ≥0.25 — uncalibrated). Footprints normalised across schemes (O→OS, ALL→NC|OS|P|S|TS); pre-Dec-2024 NC imputed.Generated by ISMexplorer v1.0.0 — longitudinal and per-release analysis of ASD Information Security Manual control changes.
