Why 0ctx exists
- Most AI workflows lose context between sessions, tools, and branches.
- 0ctx keeps one durable workspace per repo and groups activity into workstreams, sessions, checkpoints, and reviewed insights.
- The daemon is the source of truth. Supported agents retrieve through the local runtime after
0ctx enable.
