Review Comment:
   🤖 **Line 1239:** The `heartbeatClient.stop()` call is still only on the 
success path (after `return true`). If `table.rollback()` throws, the heartbeat 
is never stopped, which blocks other writers from attempting the rollback until 
it naturally expires. This was flagged in the previous review — could you wrap 
the rollback execution + stop in a try/finally? Something like:
   ```java
   try {
     // execute rollback...
   } finally {
     if (config.isExclusiveRollbackEnabled()) {
       heartbeatClient.stop(rollbackInstantTimeOpt.get());
     }
   }
   ```
