Subscribe to static loop-in confirmation-risk notifications before starting the payment deadline. Start that deadline only after server acceptance or the legacy confirmation fallback, and cancel the swap invoice when the server rejects the risk wait. Refresh selected deposits before the legacy fallback so recovered monitors use current confirmation heights.
