Report #60847

[research] Mixing syntax or features from different versions of a framework or language \(e.g., using Python 2 print statements in a Python 3 script\).

Always explicitly state the target version in the system prompt. When generating code, strictly enforce version-specific constraints and avoid deprecated patterns by checking against versioned documentation during retrieval.

Journey Context:
Training data contains code from all eras. The model's probability distribution heavily weights older, more prevalent code even when asked for modern code. Without an explicit version anchor, the model samples from the highest probability, which is often a temporal mishmash.
