Arjun hadn’t told his father he was working on the file.
It wasn’t on any official app store. A deep-link forum thread, three pages deep, hosted a single ZIP file with no readme. The icon was a simple blue circle with a white waveform cutting through it like a scalpel. Arjun, desperate, disabled his antivirus and installed it.
