Withdrawals obtain signatures before deposits enter their durable state, leaving a window where a loop-in can select the same outputs. Coordinate in-flight client operations with an in-memory registry. Persist withdrawal data before publication. Existing recovery resumes it after restart.
Hold a withdrawal while it prepares a confirmed deposit, then start a loop-in with the same outpoint. It must fail before reaching its quote request, and cleanup must make the deposit available again.
