graph

Graph workflow engine supporting directed execution graphs with conditional routing, parallel branches, and configurable join strategies (all, any, N-of-M, vote). Each node can be a step, parallel block, or route.

Used by cmd/graph-worker, cmd/graph-run.

Usage

import "cruvero/internal/graph"
