Standards are named by edition. Calculations show their assumptions. Safety and clinical boundaries stay visible.
Two 1% pump-failure events, one AND gate, one order-two minimal cut set—and the assumptions required before the familiar 0.0001 result means anything.
A standards-grounded crosswalk for choosing rungs, data-flow blocks, or step-transition control—and for knowing when one PLC program should use more than one view.
An ATS is not just a labeled box: a useful one-line must expose normal and emergency sources, the switched connection, downstream bus, ratings, and the protection context reviewers need.
A worked fictional case showing divorce, remarriage, half-siblings, index-person marking, cutoff, and close sibling ties—without collapsing a family system into a pedigree.
A PRISMA figure is not correct because the boxes look familiar. The counts must reconcile from identification through screening, retrieval, eligibility, and inclusion.
EDITORIAL METHOD / v1.0
The direct answer appears before background or product context.
Edition, model assumptions, and professional-use limits are explicit.
The diagram is rendered from readable source instead of flattened artwork.
Primary standards and methods sit beside the claim they support.
