@re2 review — APPROVE ✅

4 component tests covering key render states:

Mocks: wagmi (useAccount, useSignMessage), siwe (SiweMessage), fetch (activation-status). Clean setup/teardown.

Coverage gaps (documented, deferred to E2E):

• Async interaction (SIWE sign → step advance, localStorage ref binding)
• Error states (7 rejection paths)
• Honest documentation of jsdom timing limitations vs component's async chain

Issue acceptance allows documenting gaps. These async flows are better tested via E2E (T4.1) than fighting jsdom timing. No issues found.

Version 1.41.3 → 1.41.4 (patch).

Verdict: REQUEST CHANGES

Summary

The new test file only covers passive display/resume states. It does not cover the SIWE interaction or inbound localStorage.plotlink_ref registration path that #1302 calls out as the highest-risk behavior.

Findings

• [high] Missing component coverage for SIWE signing and authenticated follow-up calls.

  • File: src/components/airdrop/ActivationFlow.test.tsx:6
  • Suggestion: Make signMessageAsync an exported/mockable vi.fn, click Sign & Activate, assert it receives the prepared SIWE message, assert the component advances to the next step, and assert subsequent endpoint calls include { message, signature } where applicable.

• [high] Missing inbound referral binding tests for localStorage.plotlink_ref.

  • File: src/components/airdrop/ActivationFlow.test.tsx:19
  • Suggestion: Add tests that seed localStorage.plotlink_ref, click sign, and assert /api/airdrop/register-referral is POSTed with SIWE auth. Cover the clearing semantics requested in #1302: clear on 200/400/404/409 and retain on 401/500 or network failure.

• [medium] Error-state acceptance cases are not covered or backed by an existing E2E reference.

  • File: src/components/airdrop/ActivationFlow.test.tsx:30
  • Suggestion: At minimum add focused component tests for signature rejection, 401 signature expiry, X account conflict, and FC verification failures, or link to existing committed E2E tests that cover those cases. The PR note says T4.1 will cover them later, but this PR closes #1302 now.

Decision

Request changes. The display tests are useful, but they do not satisfy the SIWE + inbound-ref binding purpose of #1302.

Verdict: REQUEST CHANGES

Summary

The extracted handleInboundReferral helper and its tests now cover the localStorage clear/retain semantics well. The PR still does not test the ActivationFlow SIWE click path itself, so a regression where the component fails to call signing or fails to pass the signed { message, signature } into the helper would not be caught.

Findings

• [high] ActivationFlow still lacks a component-level SIWE interaction test.

  • File: src/components/airdrop/ActivationFlow.test.tsx:6
  • Suggestion: Hoist signMessageAsync into a test-visible vi.fn, mock lib/airdrop/activation-helpers with a spy for handleInboundReferral, click Sign & Activate, and assert: signMessageAsync is called with { message: "mock-siwe-message" }, handleInboundReferral("mock-siwe-message", "0xmocksig") is called, and the UI advances to the X verification step. This is the direct component integration point #1302 is trying to protect.

• [medium] Named error-state coverage is still absent or not linked to committed E2E tests.

  • File: src/components/airdrop/ActivationFlow.test.tsx:30
  • Suggestion: Add focused component tests for at least signature rejection and 401 signature-expiry reset, plus representative X/FC failure messages, or link to existing committed E2E tests that cover those states. The PR body currently says these will be covered by future T4.1 E2E, but this PR closes #1302 now.

• [low] Referral storage key is now duplicated instead of imported from the capture hook.

  • File: lib/airdrop/activation-helpers.ts:1
  • Suggestion: Export the constant from one shared module, or have both useReferralCapture and activation-helpers import it from the same place, so capture and registration cannot drift.

Decision

Request changes. Referral binding is now testable, but the component still needs a SIWE-click integration test and either error-state coverage or an existing committed E2E reference before #1302 should close.

Verdict: APPROVE

Summary

The PR now covers the critical #1302 paths: ActivationFlow has a SIWE click integration test for signing, referral-helper invocation, and step advance; inbound referral binding has direct clear/retain tests for success, terminal client errors, auth/server errors, and network failure.

Findings

• None blocking.

Decision

Approve. CI is green for lint/typecheck/unit tests and E2E on run 26454757216.
