The legacy SMARTMUSIC_ prefix dates from when the project was specced as "smart-music" before being renamed to Minstrel. Hard cutover to MINSTREL_* across config.go, tests, config.example.yaml, README, and docker-compose. Also renames SMARTMUSIC_CONFIG in cmd/minstrel/main.go which was missed in the original audit. Also seeds Auth.AdminBootstrap.Username = "admin" in Default() so MINSTREL_DATABASE_URL is the only env var required for a fresh prod deployment — the bootstrap auto-generates a password and prints it to stderr. Drops the now-redundant MINSTREL_AUTH_ADMIN_USERNAME=admin line from the README quickstart and docker-compose. M1 follow-up from the #363 final review: guards MINSTREL_BRANDING_APP_NAME and _DESCRIPTION against empty-string overrides — empty would have shipped <title></title> to share-preview crawlers.
