The main ISRC matching is done in the orchestrator.ts file within the same folder. Subsonic was difficult to work with when I tried to implement matching because the endpoint had a limited number of tracks it returns. So I ended using the native Navidrome search API to find the track by title and compares the ISRC. You can check out the file to have a better understanding. Feel free to reach out if you have any more questions.
