 ### Plan
 
-[PR #834](https://github.com/bitwarden/contributing-docs/pull/834) publishes the standard at
-Contributing › Diagrams and converts the contributing site's existing diagrams (PlantUML/Kroki
-sources, static diagram assets, and source-less images) to comply, so the site itself becomes the
-reference implementation of the standard. Elsewhere, legacy diagrams convert when their docs are
-next touched: images and non-Mermaid sources in repos become Mermaid code blocks, and Confluence
-attachments and images become Macro Pack's Mermaid diagram in text-input mode.
+The standard is published at Contributing › Diagrams, and the bulk of the contributing site's

+converted to comply, so the site becomes the reference implementation of the standard, with the
+exceptions noted below. Elsewhere, legacy diagrams convert when their docs are next touched: images
