Map screen flows

Author map ScreenFlows with explicit I/O, expose via OpenAPI, and record/run/debug against converted map programs, not Hub terminal Screens Flows.

OL Next map ScreenFlows are repeatable test and automation scripts for converted map programs running as legacy code on the JVM. Each flow declares input and output definitions, can be exposed as OpenAPI, and runs against the converted program, supporting record-from-player, AI-assisted generation, execution, and step-through debugging. These automate conversations with converted map programs, distinct from OL Integration terminal Screens Flows.
