Report #15080

[research] LLM suggests a Python package or API endpoint that does not exist, but sounds plausible

Cross-reference generated package names or API endpoints against a live registry \(like PyPI or the official OpenAPI spec\) before presenting the code to the user.

Journey Context:
Code LLMs are notorious for hallucinating imports \(e.g., importing a plausible-sounding utility that was never published, or an AWS SDK method that was deprecated/never added\). Because code has strict syntax, a syntactically valid but semantically fake API breaks execution. Static analysis or runtime validation against a schema is the only reliable guardrail.
