Follow the transaction that actually spends the watched deposit, require its confirmed form to spend every selected withdrawal input, persist that transaction, and stop republishing both the original and replacement.
Identify withdrawal change through its active change-family script instead of a fixed output index. Record amounts correctly when confirmed replacements reorder or add outputs.
Stop republishing an obsolete withdrawal when its confirmed spender consumes only part of the deposit group. Finalize spent deposits, release untouched deposits, and clear stale transaction references.
handleWithdrawal starts a long-lived spend and confirmation monitor, but the manager did not own its lifecycle. Manager.Run could return while a monitor was still transitioning deposits, updating withdrawal rows, or reading package-level logging state. Track every monitor with a WaitGroup and give the run loop a child context that is canceled on every exit path. Close request delivery, cancel the monitors, and join them before returning. Configure the test logger once and make monitor tests cancel and wait so consecutive race tests cannot overlap through the global logger.
Withdrawal spend monitoring followed an RBF replacement's txid while retaining the original destination script. Confirmation requests match both values, so a replacement paying a newly derived destination could remain invisible and leave deposits stuck in Withdrawing. Build the confirmation request from the actual spending transaction, use a positive spending height as its historical hint with the startup height as the mempool fallback, and identify change from the confirmed transaction's own destination. Persist the confirmation's block height and remove both original and replacement republish entries after resolution. Widen the manager store dependency to an interface so the complete transition and persistence path can be covered without a database, and add replacement, map-cleanup, and mempool-height regression tests.
