sparrow-0001: WalletUtxosEntry.updateUtxos() ArrayList.removeAll O(N^2) UTXO diff uses List.removeAll which is O(current * previous). Fix: Set-based diff via Sets.difference (same pattern already used in WalletTransactionsEntry). MEDIUM, 250x at N=1000 UTXOs. sparrow-0002: UtxoEntry.recountMixesDone stream().anyMatch O(M*I*T) Whirlpool mix chain walk streams all wallet TXOs per input per mix. Fix: HashMap<Sha256Hash, Set<Long>> index for O(1) lookup. MEDIUM-HIGH, 50x at M=200 mixes, T=1000 TXOs. MOAD-0002 (Intertangle): EventManager is a thin Guava EventBus singleton, not a god object. Wallet/network/UI coupling is event-driven, acceptable. MOAD-0003 (Leaked Context): CLEAN, no ThreadLocal usage found. MOAD-0004 (Logged Secret): CLEAN, no private keys/mnemonics/passphrases logged. SecureChannelSession has commented-out secret logging. MOAD-0005 (Thundering Herd): CLEAN, no unsynchronized cache patterns. 4/4 unit tests PASS. UNDF-2026-000000931 through UNDF-2026-000000932.
