只改决策层：第二大脑检索准确率 40%→96%，token 降 17 倍
同一 Agent 同一笔记库，把「猜文件名读全文」换成两轮 Jev 结构化选择（先选文件再选段落），并让它在答案不存在时直接说不知道。
his second brain got smarter by reading 17x less one creator rebuilt his agent's memory and changed only the decisions, same agent, same notes before: guess a file by its title, read all of it, hope it's the right one after: two quick jev rounds, which files, then which sections right section found: 40% → 96% / tokens per question: 21,000 → 1,200 the best part is the question nobody asks: is the answer in here at all? he asked for his favorite pizza topping, a thing he never wrote down, and instead of an unrelated 11,700-token file the vault just said "i don't know" a second brain doesn't rot from bad writing, it rots from thousands of small decisions nobody makes
