M1: `Sqlx` is a misleading leftover — this crate uses `rusqlite`, not sqlx. Rename the variant (and the doc reference to it) to `Sqlite`. No external pattern matches; the variant is reached only via `#[from]`. M11: `assets_root` was an `#[allow(dead_code)]` helper introduced for a test that never landed. Delete it so the dead-code allow goes with it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
