• No QL tests were added to validate the new Actix modeling. Consider adding .ql test cases to cover the ActixHandlerParam logic.

• The RemoteSource module is not imported or fully qualified. It should extend DataFlow::RemoteSource::Range to reference the correct class from the DataFlow module.

private class ActixHandlerParam extends RemoteSource::Range {

I think this is a very narrow model, but it's a decent starting point, and any models of remote taint sources are high value.

I'm aware that you have a specific database this change is targeted at, I assume you've tested it works there, but we really should have at least one test case in the repo as well. I've created #19466 to address this shortfall and also track how we're doing on other web frameworks.

#19466 has been merged into main, so if you merge latest main into this branch we'll be able to see how your model does on the test.

Also, CI says that Actix.qll needs autoformatting.

Feel free to DM me if you need any help.

I'll need to put this on hold while I catch-up on some other stuff. I'll reach out probably next week to see how the test works.
