) (mergedRecord types.ClaimsRecord, err error)

This method additionally:

  • Always claims the IBC action, assuming both record haven't claimed it.
  • Marks an action as claimed for the new instance by performing an XOR operation between the 2 provided records: `merged completed action = sender completed action XOR recipient completed action`

func (Keeper) OnAcknowledgementPacket 

func (k Keeper) OnAcknowledgementPacket(
	ctx sdk.Context,
	packet channeltypes.Packet,
