Run `./vendor/bin/lean-package-validator update` to replace missing export-ignore entries. 2. Add `--align-export-ignores` if you want aligned columns. 3. Add `--omit-header` to avoid modifying the header comment. 4. If you need a preview first, run `./vendor/bin/lean-package-validator validate --diff` and then re-run with the `update` command. Keep any non-export-ignore rules intact; lean-package-validator appends export-ignores below them. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/raphaelstolt) — claim your Tome and manage your conversions.
