C.2.2a:4.10 - What changes after the row exists

Compare the relevant readings with the local threshold named by the next action. Use the result to decide whether to keep the publication where it is, route it through a seam or prompt pattern, open a facet or endpoint question, or stop because a required reading is unknown. The receiving pattern governs the actual route, comparison, or publication decision; the chart row supplies only the position facts that decision uses.
