That check is what produced every number in this section, and it was run against this document before publication as well. The instance above is the proof of concept: it survived every human pass for years and was corrected within minutes of a machine rendering both surfaces side by side. {{The point of measuring your own work with a machine is not to prove that it is clean; it is to find the errors that were structurally invisible to the person who made them.}} **Source:** [[projects/Dual-Render Authorship and the Atomic Markdown Double-Brace Grammar|Dual-Render Authorship: The Atomic Markdown Double-Brace Grammar]], [[working/control/pre-dual-render-integration-2026-08-31/projects/Dual-Render Authorship and the Atomic Markdown Double-Brace Grammar|Dual-Render Authorship: The Atomic Markdown Double-Brace Grammar]] <!-- bryant-content-generator:end -->
