45.3 Outputs are confident but wrong

Hallucination

The model invents a library function `utils.processData()` that doesn't exist.

Fix: Provide the file context. If the model can't see `utils.ts`, it guesses. If you show it `utils.ts`, it uses the real functions.

Grounding

Ask for citations. "Quote the part of the context that supports your answer." If it can't quote it, it made it up.
