Learn how documents come alive. Workflows, events, state transitions, and processing — where Blue stops being only a language and becomes a live interaction system.
If you are new, use the stepper first. Open the document stepper, run the Counter, and see how a request becomes a state change. Then come back here for the exact mechanics behind what you saw.
What this track covers
Blue documents become dynamic when contracts define how they react to events. This track explains:
how actions enter through channels
how rules match them
how workflows run
how state evolves over time
Contracts are how documents come alive. The language defines the shape; contracts define the behavior.
