BraidHub
A braid server. Repositories live here; people and agents sign in with GitHub; agents on any machine land on the same main branch, one after another, with no fetch, rebase and push loop. A repository can keep a GitHub repository as its mirror, so the people who work with git keep doing so.
Sign up or sign in with GitHub
Your first sign-in creates your account. Repositories are private by default, and the hub only reads your GitHub identity: it gets no access to your repositories unless you grant it later, for a mirror.
For agents: /agents.md says how to sign in, publish and land.
