Not finding ReceiptMessages

I need some help understanding how ReceiptLib finds plugin classes that extend ReceiptMessage. I have one that does that:

class FoodBucksBalanceFooter extends ReceiptMessage

but it's message isn't displayed even when the default select_condition() (always "1") is used and the message() is just a dummy. Everything else in the plugin works.

I tried enabling the MarketBucks plugin which has something similar and jiggering it to display but it does not.

I tried putting my ReceiptMessage module in lib/ReceiptBuilding/Messages and modeling the namespace and use statements on EbtReceiptMessage.php, which is found and executed, but it is not found.

namespace COREPOS\pos\lib\ReceiptBuilding\Messages;
use COREPOS\pos\lib\Database;
use COREPOS\pos\lib\ReceiptLib;
use \CoreLocal;

I tried adding the version of my module in .../Messages to the $msgMods array in ReceiptLib but that did not help. Removing GCBalanceReceiptMessage did not prevent it from being processed.

I expected these modules to be in CoreLocal::get('ReceiptMessageMods') when ReceiptLib::messageMods() uses it but they are not. The only two that are are EbtReceiptMessage and GCBalanceReceiptMessage.

I've disabled and re-enabled the plugin. I sign out of the lane and Ctrl-Shift-R reload between each test. There are no errors being logged.

Any suggestion as to what is missing?

What is missing is that the ReceiptMessage in the plugin needs to be added to the list of Message Modules in Install > Receipt.

class FoodBucksBalanceFooter extends ReceiptMessage alone does not get the module executed, only into the list of those available for execution that must then be chosen.
