Research direction
Start by reproducing the A-to-B request failure described for Hmily 2.1.1 and inspect the MySQL transaction and participant logs shown in the issue. Trace the applyPay/trade transaction after A recovers, then verify that the transaction reaches the expected cancel or confirm terminal state; the issue does not name source files or tests.
