A workflow node performs or represents a bounded responsibility; an edge states how control, data, or meaning connects two nodes. Keeping these roles separate clarifies graph design.

Nodes Compute; Edges Relate

A path is an ordered sequence of connected nodes. Enumerating important paths reveals skipped checks, impossible states, and expensive loops before deployment.

A Path Is One Possible Execution Story

Data-flow edges specify values, provenance, and schemas exchanged between nodes. Separating them from control flow prevents a value's presence from silently authorizing execution.

Data Flow Answers What Moves

A knowledge-graph node should represent a distinguishable entity with a stable identity rule. Labels are display text; identifiers decide whether two mentions refer to the same thing.
