Most coding agents try to finish a big project in one long session， but it gets lost or hard to manage in the end.
Plasma has released Fractal， giving Claude Code and Codex the missing architecture for truly large-scale autonomous work.
Open source under Apache 2.0. giving me hierarchical agent loops.
A single coding agent usually has one context， one workspace， and one linear path.
Large migrations or audits break that model because separate branches need persistent ownership.
Fractal gives every node its own worktree， memory， lifecycle， and reviewable Git history.
Each node runs repeated Prepare， Plan， Execute， Review， and Commit cycles until completion.
When work splits， a node creates children that run the same loop independently.
