利用微痕分析与残留物检测技术，高星团队确认云南甘棠箐遗址中35件木质材料系古人类精心制作、长期使用的专业工具，主要用于挖掘植物根茎等作为食物。为测定这些木器的年代，古生物地层学、古地磁学、光释光和电子自旋共振等多种方法被交叉使用，最终检验、确认它们制作于距今约30万年前的旧石器时代早期，是迄今东亚地区所见最古老的木器。这项发表于国际知名学术期刊《科学》上的研究，有力反驳了过往认为中国旧石器时代技术发展迟缓的观点。，更多细节参见safew官方下载

Local sandboxing on developer machinesEverything above is about server-side multi-tenant isolation, where the threat is adversarial code escaping a sandbox to compromise a shared host. There is a related but different problem on developer machines: AI coding agents that execute commands locally on your laptop. The threat model shifts. There is no multi-tenancy. The concern is not kernel exploitation but rather preventing an agent from reading your ~/.ssh keys, exfiltrating secrets over the network, or writing to paths outside the project. Or you know if you are running Clawdbot locally, then everything is fair game.
