…e check 1. Add Manager.getCachedTransactionSize() = pushTransactionQueue + pendingTransactions + rePushTransactions to expose the true cached transaction count across all three queues. 2. Fix isTooManyPending() to include pushTransactionQueue, which was previously omitted, causing the pending threshold to be underestimated. 3. Update TransactionsMsgHandler.isBusy() to factor in the Manager cache size via TronNetDelegate.getCachedTransactionSize(), so the node stops accepting TRX INV messages when the full pipeline is busy. 4. Make the busy threshold configurable via node.maxTrxCacheSize (default: 50000), replacing the hardcoded MAX_TRX_SIZE constant. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Good targeted test for the new busy logic — mocking TronNetDelegate to control the cached size is exactly the right approach 👍
Tiny nit: the magic number 50_001 couples the test to the default maxTrxCacheSize. If someone tweaks the default later, this test silently keeps passing only because 50_001 > 50_000 happens to hold. Using Args.getInstance().getMaxTrxCacheSize() + 1 would be future-proof, and adding a boundary case (e.g. exact-threshold returns false) would catch off-by-one regressions. Totally optional polish.
