MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The createSurface example uses a remote catalogId (https://a2ui.org/specification/v1_0/catalogs/basic/catalog.json) that renderers are expected to resolve and whose "instructions" field is explicitly used to guide the LLM, so fetching that URL at runtime would directly control agent prompts.
