[counterintuitive] chain of thought always improves accuracy

Evaluate CoT on a per-task basis; use direct answering for trivial or highly memorized facts, and avoid CoT when latency/cost is a constraint and the task is simple.

Journey Context:
CoT is great for math/logic, but for simple factual recall or tasks where the model already has strong priors, forcing CoT can introduce reasoning errors that override correct memorized answers. It also amplifies bias if the reasoning path is forced, and drastically increases latency and token cost.
