[gotcha] AI-generated markdown contains hallucinated links, references, and interactive elements that look functional but go nowhere

Sanitize all AI output to strip or neutralize ungrounded URLs, link references, image sources, and interactive HTML elements. If rendering AI markdown, validate all links against an allowlist or replace them with non-interactive styled text. Never render AI-generated HTML or JSX as interactive components without explicit validation. For code generation, validate package names and API endpoints against real registries.

Journey Context:
LLMs are trained on vast corpora of markdown and HTML, so they naturally emit output containing hyperlinks, image references, import statements, and even interactive elements. Users click these expecting navigation or functionality, but the links are hallucinated—pointing to non-existent pages, wrong URLs, or fabricated package names. This is the 'uncanny valley' of AI output: the response looks more functional and authoritative than it actually is, creating a trust gap when links 404 or packages don't exist. The gotcha is that standard markdown renderers make these hallucinated elements fully interactive and clickable, lending them false credibility. The fix requires treating all AI-generated URLs and references as untrusted by default—a posture that feels overly cautious but prevents the most common and damaging trust-breaking moment in AI UX.
