So, we are right in the forum where we discuss about phpBB compliant code to be applied for the development of extensions and before they are made available to the public to be tested.
I'm sorry to ruin the party, I understand the efforts due to the purpose, I'm part of it ... but here it seems to me the case to ask if first you have ever read the minimum set of instructions provided in order to be able to adhere to the minimum of the standard lines?

The fact that an extension in project phase seems to work doesn't say anything about the fact of its potential validation, in your case, only having read one of the files from your repository, my judgment is negative I'm sorry... I hope you have the time and the will to review your project.
Note: I also spent some time to understand what "introduciator" meant and my research provided me with a result from the Spanish that in English would be "Introducer".
