CattaFish
CattaFish's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @CattaFish appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.

CattaFish/QQNT-Patcher: 基于静态 Dex 修改的 QQNT 自动化 Patch 工具，无需 LSPosed/Xposed 等 Hook 框架，免 Root 运行，规避运行时 Hook 特征检测
- Reuse a worked example: the commit “去签实现切换为 TinkerApplication 继承链注入方案” (32 files · C, Python).
- Answer from QQNT-Patcher's real C source instead of memory (API design and specification).
- Where does QQNT-Patcher handle “去签实现切换为 TinkerApplication 继承链注入方案”?
- What does killer_native do in QQNT-Patcher?

The corpus is the whole repository at the pinned commit, not only the files of the selected commit.
Not installable yet: this corpus is not in the hub registry until its licence review passes, so xerj corpus add and xerj ask cannot fetch it. It becomes installable when this card says live in the hub.
Sign in with GitHub or Hugging Face to see more: every selected commit in full (commit date, every folder, licence review state, pin) and the pack builds of each corpus.
