用 Jev 在 agent 每个决策点做类型化路由
作者算账：便宜模型绕路比留在前沿模型贵 49%，因为被路由的是上下文而非 token，于是把「这轮看哪些块、复用还是重建缓存、放行/询问/拒绝命令」都交给 Jev 做类型化提问。
the cheap-model detour in your agent costs 49% more than staying on the frontier model, and its why u need JEV. Opus -> Sonnet -> Opus looks like savings on the price list. the small model loads the whole context, the big one reloads whatever changed, you pay for the transcript twice. routing priced per token is the bug. context is what gets routed. so the notes put one typed question to Jev at every decision point: > which chunks does this turn get to see > reuse the cached prefix or rebuild it > allow, ask or deny this command > which files does the subtask touch, and which provider may go near them the symptom table, the routing math, a checklist the notes skip, three skeletons you can paste today.
