Mermaid Diagrams

Validate Mermaid diagrams render correctly before shipping. Open the HTML artifact in a browser and check every diagram visually — syntax errors show as broken renders, not error messages.

Common failure modes:

Unquoted labels with punctuation break the parse
Bare lowercase end collides with subgraph terminator
Node IDs starting with o or x after edge markers get misparsed
Custom fills without matching text color make labels unreadable

See resources/mermaid-authoring.md for the full authoring rules (quoting, line breaks, reserved words, themes).

Markdown Links

Check that relative links between pages resolve. When building a multi-page artifact or KB, broken cross-references silently rot — verify each link target exists before committing.
