Upgrade to 2.4.5-p1 app/code modules not recognized in setup:upgrade command

Upgrading from Magento 2.3.x to 2.4.5-p1, having sorted through the various PHP 8.1 issues, running setup:upgrade from the cli finishes, but the front end reports the standard Please upgrade your database: Run "bin/magento setup:upgrade" from the Magento root directory. The following modules are outdated: error.

There are some really basic modules in the listing that have entries in the setup_module table, and no other changes have been made to the modules, and they are enabled as well.

For example:

Hackathon_EAVCleaner schema: current version - none, required version - 0.0.1

The module’s module.xml has version 0.0.1 as expected, and the setup_module table also has 0.0.1 – but it looks like Magento is not recognizing the in-code version number to match to the setup_module version during the setup:upgrade command.

Is there something about the in-code module that needs to be updated in order for Magento to recognize the module is there?
