 - [Phase 04-review-download-security]: [04-03] Security checkbox must be clicked before testing action buttons — disabled buttons don't fire onClick in jsdom
 - [Phase 04-review-download-security]: [04-03] vi.stubGlobal must come after vi.clearAllMocks in beforeEach — clear order matters for mock reliability
 - [Phase 04-review-download-security]: [04-03] Native DOM .disabled/.checked properties used instead of jest-dom matchers — jest-dom not installed in this project
+- [Phase 04-review-download-security]: [04-04] No logic changes needed in App.tsx — Math.min clamp already handled 4 steps correctly once ReviewStep added to array
