Hello HN ,

I built a knowledge graph engine for codebases

- Records why each change was made — written back by agents as they work, so it gets better the longer you use it - Dashboard stays in sync with commits and updates from GitHub and GitLab - Flags stale files/code and deranks them internally, so the graph stays current - Token savings in the range of 78 to 99.74%. - Connects to claude code, codex , opencode etc I will be happy to talk about Graph , sych updates ,persistent memory and also how it detects stale files and token savings ?
