Today sgit has path history, signed authorship, signed tags and verification, butandnosinceblamesgit-ai 0.27.0 on 28 October, blame, grep and noline-levelbisect.merges on the client; bisect is designed but not yet built. Where it is behind on its own terms: a partial clone of a long history still walks the commits one request at a time, so a folder with all 1,295 commits takes nearly four minutes, and a depth avoids it; `history log` for one file over that history takes minutes of CPU; one server process queues concurrent full clones; and the largest vault it has been proven on is 35,000 objects and ten agents, not 100 GB and 30,000 merges a day. Being designed for something is not the same as being proven at it. 14 unchanged paragraphs, under What it means {#means}, What this does not claim {#limits}, Where this comes from {#sources} [← v1.3.0](v1.3.0.md) · [all versions](../scion-and-sgit.md) --- *[Site index for agents](../../../llms.txt) · [HTML version](https://newsroom.sgit.ai/articles/versions/scion-and-sgit/v1.4.0.html)*
