Shadow DOM visibility
Shadow DOM encapsulates component markup behind a host element and a shadow root.
How it works
Browser-based tools can inspect open shadow roots, while raw HTML parsers see only the host. Closed roots further limit programmatic inspection.
How to validate it
Place an equivalent labeled fact in light DOM, open shadow DOM, and closed-shadow UI, then report extraction and citation separately.
Common failure
Using encapsulation for primary article text can create inconsistent readings across crawlers, accessibility tools, and archival systems.
