feat(sub-workflow): hierarchical workflow composition via SubWorkflowNode#65
Merged
Conversation
…Node
Introduces the Sub-workflow implementation, enabling nested workflow execution with tenant-aware propagation and push-time graph validation.
Core & Execution:
- Added SubWorkflowNodeExecutor with a MAX_DEPTH = 16 safety cap.
- Implemented SubWorkflowGraphValidator for cycle detection and dangling reference checks (single-pass DFS).
- Added _tenant_id and context propagation for nested execution.
DSL & CLI:
- Introduced subWorkflow(id) { } builder with imports() and writes() mappings.
- Added --with flags on run, validate, and visualize for local sub-workflow seeding; build does not accept --with — sub-workflows push independently.
Server & Persistence:
- Added WorkflowPushLock using pg_advisory_xact_lock for cluster-wide concurrency control during workflow updates.
- Integrated push-time validation in WorkflowRegistryService.
- Refactored server services into specialized domain modules (Registry, Execution, Query, State).
Includes a comprehensive update to all module READMEs and developer guides to reflect the new architecture and package structures.
