Overview
A graph can be functionally correct and still be difficult to maintain. Hidden lines, ambiguous prompt nodes, duplicated settings, or nodes positioned far outside the default frame create avoidable errors.
Caching and workflow metadata also change how work should be reused. A saved JSON graph preserves an explicit workflow, while an image with intact metadata can preserve both the visible result and the graph that produced it. Both are faster and safer than rebuilding a complex graph from memory.
