+## Description
+
+Correct Mermaid syntax/rendering issues across the documentation vault and validate all Mermaid blocks.
+
+## Details
+
+Source PRD: .taskmaster/docs/prd-mermaid-diagram-rendering-stabilization.md. Scope covered 57 Mermaid blocks and 11 failing blocks. The source PRD records that all targeted files now pass mmdc parse validation and the full vault sweep passes.
+
+## Verification
+
+Run the same mmdc-based syntax validation across all Markdown Mermaid blocks and confirm zero parser failures in Obsidian/markdown previews.
