-/**
- * Tests for CoinTransferBuilder self-transfer (stakeClaimRewards).
- *
- * HBAR staking rewards are claimed by submitting a 1-tinybar CryptoTransfer
- * where sender == receiver == accountId. Hedera atomically flushes
- * pending_reward into account balance on any CryptoTransfer touching the
- * account. staking-service uses this as the CLAIM_REWARDS operation.
- *
- * The key behaviour under test:
- *   buildTransferData() must produce TWO separate accountAmounts entries:
- *     [{accountId, -1}, {accountId, +1}]
- *   The Hedera SDK TransferTransaction merges same-account entries (nets to 0),
- *   so CoinTransferBuilder.buildTransferData() bypasses that by building the
- *   proto list directly.
- *
- *   initTransfers() must reconstruct the self-transfer from serialised bytes:
- *   it filters for positive amounts only, so recipients[0].address == source.
