[Q-Learning] Failed to save model: ${err}

Error message

[Q-Learning] Failed to save model: ${err}

What it means

Log warning in saveModel: serializing or writing the Q-learning model to disk (writeFileSync) failed; saveModel returns false so callers know persistence was skipped while learning continues in memory.
