 ## Acceptance Gate Before Marking Python Scripting “Complete”
 
-- [ ] Render-time macros run through Python script path in production generation flow.
+- [ ] Users can create new Python macros that execute in production generation flow.
+- [ ] Python-based and JS-based macros coexist in production generation flow.
 - [x] Scripts directory external changes are synchronized reliably.
 - [x] Runtime boundary decision implemented and protected by tests.
-- [ ] Legacy JS macro path removed (or explicitly retained with documented rationale).
+- [ ] Coexistence/dispatch behavior is documented and covered by tests.
 - [x] `npm test` and `npm run build` pass.
