Why flagged

The package builds a patched audio HAL from source for Waydroid to enable high-resolution audio with Apple Music; it downloads source code from GitHub repositories (including the maintainer's fork) without verifiable checksums, but all built components are self-contained and intended for local use, with no evidence of malicious behavior or remote code execution.
