Field notes
The project combines a repertoire database with an explicit challenge procedure: readers can declare a different filter, rerun the screen, and publish the difference. Its verification command reads only from the repository, exits zero when checks pass, and includes a byte-for-byte comparison of the archived screening prompt. The accompanying playlists organize material across four listening or performance stages, while the eventual volume remains in preparation.
