[MEDIUM] Missing integration test for complete claim lifecycle

[kilodesodiq-arch]

Engineering Gap

No single integration test covers the complete claim lifecycle: campaign create → claim create → AI verification → approval → onchain disburse → archive. Tests are fragmented across unit and e2e files with mocked dependencies.

Codebase Evidence

• app/backend/test/verification-lifecycle.e2e-spec.ts: Covers verification flow but not full lifecycle
• app/backend/test/claims.e2e-spec.ts: Claims API tests with mocked onchain
• app/backend/test/critical-flows.e2e-spec.ts: Critical flows but uncertain coverage

Risk Profile

End-to-end aid distribution regression undetected.

Remediation Strategy

Write integration test with real SQLite/PostgreSQL, mocked AI service, and mocked onchain. Create campaign, create claim, verify, approve, disburse, archive — assert each state transition.

Success Conditions

• Full lifecycle integration test added
• All state transitions verified
• Error paths tested (invalid transitions)

Change Surface

New test: app/backend/test/claim-lifecycle.integration-spec.ts

Security Review

No security impact.

Completion Checklist

• Implementation completed
• Peer reviewed
• Test passing
• Ready for merge

Hi, I would like to work on this issue if it is still available.

Planned approach:

• Add app/backend/test/claim-lifecycle.integration-spec.ts as a focused lifecycle integration test.
• Cover campaign creation, claim creation, AI verification with a mocked AI service, approval, mocked onchain disbursement, and archive state transition.
• Assert each expected state transition and include at least one invalid-transition/error-path check.
• Reuse the repo's existing backend test setup and avoid broad production-code refactors unless the test exposes a small setup gap.

I will wait for assignment before opening a PR so this follows the GrantFox workflow.
