  "description_en": "OtterSec researchers describe an agent pipeline that reconstructed Rust source for the closed-source GoonFi V2 Solana program until a rebuild with the original toolchain reproduced the deployed ELF. Per-function instruction scoring, a deterministic merge judge and bans on assembly and other score-gaming constructs steered the agents; matching function order and panic-location paths closed the last differences. The article and a companion repository document the method and a verification script, while the internal tooling and agent transcripts remain unpublished.",
  "description_zh": "OtterSec 研究人员介绍了一套智能体流程：为闭源的 GoonFi V2 Solana 程序重建 Rust 源码，直至用原工具链重新构建即可复现所部署的 ELF。逐函数指令评分、确定性合并评审，以及对汇编等刷分写法的禁用约束引导智能体工作；对齐函数顺序和 panic 位置路径后，最后的差异得以消除。文章与配套仓库记录了方法和验证脚本，内部工具及智能体对话记录仍未公开。",
