Report #100773

[research] Generated code references non-existent APIs, packages, or functions

For any library call or package not already in the codebase, look it up in the package index or official docs and execute the code; use static analysis and unit tests to catch hallucinated symbols.

Journey Context:
Code models confabulate plausible API names and argument signatures. Execution-based benchmarks show these hallucinations are common and execution is the most reliable filter; syntax checks and type checkers catch some errors, but only running the code exposes missing packages.
