Alisizationed/allied_testing_1 — reverse-engineered prompt

I want you to turn this repo into a working Java app that feels complete and easy to run. There is basically no README, so please inspect what is already in src, config, and the build files, figure out the intended direction, and fill in the missing pieces without inventing anything too fancy.

Make it runnable locally and with Docker if that is what the existing setup suggests. It should start cleanly, use sensible config, write useful logs, and include enough test coverage that I can trust the basics. If parts are stubbed out or broken, finish them in a practical way and keep the code simple and organized.

Please also add a clear README that explains what the app does, how to start it, how to run tests, and any environment settings I need. If something is unclear, make a reasonable choice and note it. You can look up current docs online if needed.
