Execution Modules (Adapters)

Module contract

• Base: VModule implements Module.
• Map I/O: MapIOModule for modules that read/write state maps.
• Branching: BranchingModule returns an outcome to drive control flow.

Loading modules

• Each ExecModule.className is resolved to a Spring bean or reflectively instantiated.
• Properties are copied from ExecModule into the module instance before execution.

Parallel groups

• Add { "parallel": true, "parallelGroup": "A" } in moduleData to run as a group.
• Outcomes are aggregated with priority: FAILURE > CONDITIONAL > DEFAULT.

Authoring new modules

• Annotate with @Component and @VModuleAware.
• Implement MapIOModule to participate in state passing and branching.
• Keep side effects idempotent and log meaningful metrics.
