The demo catalog now has two additional independent service entries: C supports a Demo invoice and D does not. Both start without a Mello verification record, completing the four invoice/certification combinations alongside the existing reviewed A/B entries.

C is fulfilled by the existing Seller B endpoint and D by Seller A, using their current quotes and seller identities. Service display names distinguish the entries while the UI identifies the actual provider. Bazaar still matches the complete endpoint/payment terms, and verification remains specific to each service ID.

The API pre-deploy step registers missing C/D records and audit events idempotently, preserving existing services, reviews, policy and purchase history. The additive 20260906010000_service_display_name migration runs before API startup; Web then displays names in the survey, policy list and purchase records.

Validation: 394 API unit tests, 9 frontend tests and 58 focused database integration tests passed locally, with API type checking and repository lint. Integration coverage includes concurrent registration, preserving later edits/reviews, rollback on an ID conflict, independent certification gating and a complete mock purchase/invoice for a named unreviewed option.

Deployed merged commit 9b3eda1ffaf26bcbe138003c96127256c950e2b2 to production.

• API 7249e8a8-d4fe-477a-9a4a-b319eeb4d78f and Web f77fe2bd-9376-4d01-b356-0e20cc3d3b49 both reached SUCCESS. The service-name migration applied and the pre-deploy registration created C/D.
• Live read-back confirms C has a Demo invoice, D has no invoice, and both are UNREVIEWED. The A/B verification records and company policy match the pre-deployment snapshot.
• Production browser tests passed all four requirement combinations (1 / 2 / 2 / 4 results), C selection gating, reload persistence and desktop/mobile layouts. All four test requests remain WAITING_SELECTION; purchases stayed at 10 and the settled amount stayed unchanged.
• PR CI and merged-main CI passed.

The Railway service domain had changed to mello402.up.railway.app. WEB_PUBLIC_URL and API WEB_ORIGIN now match that domain; login and health checks passed at the new address.
