Apple's Music app cannot read FLAC, so getting a lossless library onto an iPod requires a converted copy somewhere. This keeps that copy beside the library on a NAS rather than on a laptop, and keeps it current unattended. Walks a source tree and reproduces it path for path as MP3: tags and cover art carried across, already-MP3 sources copied rather than re-encoded, and mirror files whose source has gone deleted along with any directories they emptied. The source library is never written to. Freshness is tracked by modification time -- an encoded file is stamped with its source's mtime, so a file is stale exactly when the two differ. That keeps runs idempotent without a database that could fall out of step with whatever owns the library, which here is Lidarr. Encodes go to a temporary file and are renamed into place, so an interrupted run cannot leave a truncated MP3 that the next run mistakes for finished work. A lock file in the mirror root prevents overlapping passes. Ships as a Python package with a console script, a container image with a TrueNAS Scale compose file, and a Nix flake providing the package, an overlay and a dev shell. The test suite runs real ffmpeg encodes rather than mocks -- the failures worth catching are in what ffmpeg does with tags, cover art and container formats.
