[counterintuitive] Hallucination in code is just syntax errors

Treat hallucination as semantic, not syntactic: run generated code in isolation, pin dependencies, and verify every imported symbol against real installed versions.

Journey Context:
The term 'hallucination' is often associated with made-up facts, but in code the most dangerous failures are plausible-looking APIs, deprecated functions, or subtly wrong signatures that compile or parse fine but behave incorrectly. Static analysis will not catch these because the code is internally consistent but externally invalid. The right defense is integration: every generated snippet must be executed or type-checked against the actual dependency graph, and dependencies must be pinned so the model's training-world assumptions do not silently drift from the runtime reality.
