Jev + Opus 5.5 拆分 agent 决策循环
让 Jev 只做过滤无效路径、选 provider、选四步动作、复查过期决策，Opus 专注推理写码，决策可记录可回放。
jev + opus 5.5 turns 4 agent decisions into a much cleaner loop. instead of letting one model control every branch, jev only handles 2 narrow jobs while the host keeps the hard limits. → filters invalid routes before selection → chooses from real provider/model candidates → picks 1 of 4 steps: inspect / implement / verify / answer → rechecks stale decisions before execution opus stays focused on reasoning, coding and synthesis. jev only decides what happens next inside options the app can actually verify. each decision can then be logged, replayed and compared later, turning 1 opaque agent loop into something you can actually inspect.
