Project goal

Build a root-required Android app + Magisk module that provides reliable per-app volume control on Android 15 and ideally older versions.

Key requirements

• Must run as a privileged system app installed via Magisk.
• Must detect active audio sessions and let the user control per-app volume in real time.
• Must also allow preset volumes for installed apps.
• Maintain documentation, TODO list, and current status log.

Working rules

• Work autonomously: implement a feature, check build, commit, then move to next.
• Keep docs/ updated, especially docs/ARCHITECTURE.md, docs/RESEARCH.md, and docs/BUILD.md.
• Keep TODO.md current and prioritized.
• Keep STATUS.md updated with what is being worked on and the last update date.
• Prefer minimal dependencies and straightforward, stable APIs.
