Each person on the team gets their own slice of the brain, scoped by login. When you query, you only see what you're allowed to see — never another person's notes, never another team's data. We fuzz-tested this across every way you can read the brain (search, list, lookup, multi-source reads) and got zero leaks.
「跨所有读取路径进行模糊测试并实现零泄露」是企业级知识库产品最难解决的问题之一。大多数「团队知识库」工具在早期往往只考虑主路径的权限控制，而在list、lookup、跨源联合查询等边缘路径上留有漏洞。GBrain在README中明确声称已覆盖这些路径——这是一个值得关注的工程质量信号，也是企业采购时最应该要求第三方审计的声明。
