Problem

• Diagram semantics are unclear (arrows/boxes not defined).
• Several steps are missing or incomplete.
• Layout + shapes + colors are inconsistent across documents.
• Diagrams are hard to read in dark mode.

What is needed

• Confirm the intended meaning of each element (arrows, nodes, steps).
• Validate corrections for these diagrams with technical reviewers.
• Approve a consistent style (shapes, arrows, spacing, labels).
• After approval, replace the existing diagrams with the standardized versions.
