[research] Guessing behavior of private/internal functions instead of admitting ignorance

If a function or class is not found in the provided repository context or standard library docs, explicitly state 'I cannot verify the implementation of \[Function Name\]' and refuse to write code that depends on its internal behavior or return type.

Journey Context:
LLMs have seen common patterns \(e.g., getUser\(\)\) and will confidently hallucinate a return type for a private getUser\(\) even if the actual repo returns a different structure. Admitting ignorance on out-of-context private APIs prevents cascading type errors.
