# Round 2 checkpoint — Task 2: main E2E verification

Date: 2026-09-27

## Result: PARTIAL (fixture/API regression PASS; full live E2E BLOCKED)

### Existing harness/account review

- Reused the existing `integration_test/automated_matching_flow_test.dart`, current server/API tests, and service/widget fixtures; did not create a new system test database or permanent accounts.
- The opt-in real-DB Destination Poll vote test requires `TRAVELIN_POLL_TEST_DB_*` and a schema prefixed `tourapp_poll_vote_test_`; it was run and skipped because the isolated DB config is not present.
- Reused Round 1 evidence rather than repeating it: Gemini `/api/analyze` returned HTTP 200 for Thai-language Japan/budget/interest input; Destination Poll China E2E had passed on Emulator in its earlier checkpoint.
- Round 1 authentication checkpoint records one authorized Admin login attempt returned 401 and no authorized Agency credential available. No credentials were guessed or reset in this round.

### Verification performed this round

- `flutter test` targeted suite — 87 passed. Covered NLP parsing, Matching V2 constraints/waiting, group/offer service contracts, Agency registration/pending/approval/bid API behavior in in-memory fixtures, voting/tie/finalization and winner-only payment policy, development slip verification, Trip Hub, Travel Documents, notifications, and trip-rating widget flow.
- `flutter test integration_test/automated_matching_flow_test.dart -d emulator-5554` — 1 passed on Android Emulator; MockClient only, no API/database write.
- `flutter test integration_test/destination_poll_japan_test.dart -d emulator-5554` — 1 passed on Android Emulator; MockClient only, no API/database write.
- `flutter test test/server/destination_poll_vote_database_test.dart` — skipped safely; isolated poll DB environment is not configured.
- `flutter analyze integration_test/destination_poll_japan_test.dart test/server/destination_poll_catalog_policy_test.dart test/widgets/destination_poll_entry_test.dart` — no issues.

### Not proven / blockers

- Full live cross-subsystem E2E is not proven: there is no isolated live E2E database/configured DB test schema, and authorized Admin/Agency credentials are unavailable. API fixture tests prove individual contracts but do not prove a single persistent end-to-end lifecycle.
- No real payment provider was called; slip/payment behavior used the development verifier and fixture tests only.
- Emulator rendering/interactions passed for Matching and Japanese Poll fixtures, not live API sessions. Portal protected-page UI still needs an authorized Agency/Admin session.
- No synthetic data requiring cleanup was written. No database connection or business data mutation occurred. Groups #115 and #102 were not accessed or changed.
