🔴 Critical Rules Documented​

All 15 critical rules are documented with:

  • What NOT to do (❌ example)
  • What TO do (✅ example)
  • Why it matters
  • Penalty for violation

The 15 Rules:​

  1. NEVER set IDs on new objects (JPA handles it)
  2. ALWAYS use ThorAPI generated services
  3. ALWAYS eager-load before async boundaries
  4. ALWAYS use REQUIRES_NEW for async state persistence
  5. ALWAYS propagate SecurityContext to async threads
  6. Use module config properly (Map<String, Object>)
  7. Modules chain by moduleOrder (float)
  8. Thread data between modules via workflow state
  9. ALWAYS validate server-side
  10. Module exceptions → return error maps
  11. Implement POST /v1/vaiworkflow/{id}/trigger endpoint
  12. Frontend ID handling (never set ID)
  13. Dirty-state tracking with auto-save
  14. Module config forms for all 20+ types
  15. API data lookups for auto-complete

📊 Implementation Scope​

Frontend (TypeScript/React)​

  • 5 NEW Components:

    • ExecModuleConfigBuilder.tsx (unified form editor)

    • InspectorPanel.tsx (show module list)
    • index.tsx (integrate components)
    • workflowSlice.ts (dirty-state tracking)
    • WorkflowService.ts (auto-save, conflict detection)

  • 1 NEW File (module schemas):

    • execModuleCatalog.ts (all 20+ module definitions)

Backend (Java)​
