What an agent can do with the Sona corpus

LhacenMed/Sona: Offline music player for Android. Fast library, playlists, synced lyrics and a full player with colours from your album art. No accounts…

Look up how Sona implements android, android-application, audio-player, with answers cited to file and line.
Reuse a worked example: the commit “add a Now Playing home screen widget” (33 files · Kotlin).
Answer from Sona's real Kotlin source instead of memory (Web and frontend platform).

Example questions

Where does Sona handle “add a Now Playing home screen widget”?
How does Sona implement android?
What does app/src do in Sona?

Paste it into your AI agent. It clones the repo at the pinned commit and indexes it on your machine.

Search the GitHub repository LhacenMed/Sona with XERJ (https://hub.xerj.org/corpus/lhacenmed--sona).
Run these in a shell, in order, and check each result before the next:
1. xerj --help  (success: it prints usage). If xerj is missing: curl -fsSL https://xerj.org/get | sh
2. git clone https://github.com/LhacenMed/Sona Sona && git -C Sona checkout 749e807d07b8d0b4bd0cd1fea90508f53b9a216a
3. Start a local node and leave it running: xerj --insecure --data-dir ./xerj-data
4. xerj autoindex ./Sona --url http://127.0.0.1:9200 --prefix sona --progress plain
5. xerj autoindex map --url http://127.0.0.1:9200
Then answer my question from the indexed files and cite the ax_path of every hit. Query syntax: https://xerj.org/llms.txt
