Report #80298

[research] LLM suggests importing software packages or APIs that do not exist

Constrain code generation to a known dependency manifest \(e.g., requirements.txt, package.json\) provided in the context, or force the model to use a tool to search a live package registry before inventing an import.

Journey Context:
LLMs predict the next token based on programming patterns, often generating highly plausible-looking but entirely fictitious package names \(e.g., python-foobar\). This is a severe security and factuality issue \(see slopsquatting\). Grounding against an actual package list or API schema is mandatory.
