[research] Agent writes buggy code, and when asked to explain it, invents a confident but fabricated technical justification

Decouple generation from explanation. When debugging, force the agent to execute the code in a sandbox first, then explain the execution output, rather than asking it to rationalize its own static text.

Journey Context:
LLMs are post-hoc rationalizers. If asked 'Why did you write X?', they will generate a plausible-sounding explanation even if X was a random statistical artifact. This makes them double down on errors. Grounding the explanation in empirical execution results \(stdout/stderr\) forces the model to confront reality rather than inventing a narrative.
