Mostly supports codex, customizable graph orchestration so it supports all weird flows you can think of (ralph loops, spawn worktrees, write review). Bootstraps itself nowadays (i.e. the last ~900 commits).

supports script and agent based nodes in the graph. i.e. you can paply post condition checks via script nodes or reviewers.

Completion is marked when a node in the graph moves a token from processing to failed/complete.
