Elsa.Activities.Do Extension Points

This module does not expose replaceable service contracts in v1. Its activity-owned contracts are:

  • Do.Body child slot (at most one body activity)
  • A Done composite outcome emitted once the condition no longer holds or a body Break ends the loop
  • A Break body outcome (matched by name) that ends the loop early
  • A distinct engine IterationId per pass, threaded through the body child's ActivitySchedulingProvenance.IterationId (ADR 0028 / #259)

Cross-domain contributions

  • DoStructureHandler implements IActivityStructureHandler (Elsa.Workflows.Design.Core). It projects the body branch slot from the authored structure, compiles the executable structure (the body branch node id), and round-trips both through publishing so the runtime resolves the body without re-reading the design document. Do is a condition-only loop with no per-iteration item or index and is not a container scope, so it declares no container-scoped variables (SupportsScopedVariables defaults to false).
