用 Jev 加 GPT-6 Astra 搭三层第二大脑笔记系统
把笔记操作分给代码、Jev 和 Astra 三层，Jev 守链接、晋升、召回三道关，Astra 只负责写最终内容。
Jev + GPT-6 Astra is the second brain setup that doesn't rot... past a few hundred notes, writing isn't the problem anymore he problem is the thousands of tiny calls: is this a duplicate? does it contradict March? is it even in here? so every operation goes to exactly one of 3 layers: - code enforces: changed, expired, duplicate text, over budget -> free - Jev judges: link or not, promote or not, relevant or not -> fractions of a cent - Astra writes: interviews, compiled pages, the final answer -> only on what survived and Jev guards 3 gates: - link gate: labels note pairs as duplicate / related / revises / contradicts, you approve - promotion gate: nothing becomes a "fact" unless it's supported, in scope and not conflicting - recall gate: which files -> which sections -> enough evidence -> only then Astra reads Astra builds the brain, Jev keeps it honest the full version will be available soon in a new article
