E2E Test Selection:

The changes in this PR are focused entirely on the Perps feature, specifically the withdrawal request tracking system:

1. PerpsController.ts (CRITICAL): Adds two new state fields (lastCompletedWithdrawalTimestamp, lastCompletedWithdrawalTxHashes) for FIFO withdrawal completion tracking. Adds a new completeWithdrawalFromHistory() method. Changes withdrawal failure handling so failed withdrawals are removed from the queue rather than retained. This is a significant behavioral change to the withdrawal lifecycle.

2. AccountService.ts: Refactors withdrawal completion/failure handling - direct completions now remove from queue and record txHash; failures remove from queue. This changes how withdrawal state transitions work.

3. useWithdrawalRequests.ts: Major refactor of the withdrawal tracking hook - switches from getUserNonFundingLedgerUpdates to getUserHistory API, implements FIFO queue matching, reduces poll interval from 10s to 5s. This is a significant change to how the UI tracks withdrawal completion.

4. Migration 128: New migration that clears deposit/withdrawal request queues for clean state with new FIFO tracking. This affects all existing users upgrading to this version.

5. initial-background-state.json: Updated with new state fields - affects test infrastructure.

Tag Selection Rationale:

• SmokePerps: Primary tag - all changes are directly in the Perps withdrawal flow. The FIFO queue-based withdrawal tracking, new controller methods, and hook refactor all need validation. Per SmokePerps description, also requires SmokeWalletPlatform and SmokeConfirmations.
• SmokeWalletPlatform: Required by SmokePerps tag description (Perps is a section inside Trending tab). Also relevant because the migration 128 touches PerpsController state which is part of the background state.
• SmokeConfirmations: Required by SmokePerps tag description (Add Funds deposits are on-chain transactions). The withdrawal flow involves on-chain transactions.

Risk Assessment (Medium):

• Changes are well-scoped to Perps feature only
• No changes to shared navigation, Engine initialization, or cross-cutting components
• The migration (128) is a risk factor as it clears existing withdrawal/deposit queues for all users
• The FIFO matching logic change is a behavioral change that could affect withdrawal completion detection
• The initial-background-state.json update ensures test infrastructure is aligned with new state shape
• No impact on other wallet features (accounts, networks, swaps, etc.)

Performance Test Selection:
The useWithdrawalRequests hook was significantly refactored with a reduced poll interval (10s → 5s) and new FIFO matching logic. The PerpsController gained new state fields and a new method. The more frequent polling (every 5s vs 10s) could impact performance in the Perps flow, particularly during active withdrawal sessions. @PerformancePreps covers perps market loading, position management, add funds flow, and order execution - which includes the withdrawal flow that was refactored.
