Participant questions
Which API style is assumed?
REST-first with optional GraphQL discussion; both patterns appear in exercises.

We do not cover payment tokenization—only catalog and cart service contracts.
Recent reflections
The optimistic rollback drills mirrored our Busan warehouse rollout—still wish we had one more week on edge cases.
