Reviewed EuclidParameters corresponds to blueprint EuclidParameters with checked argument positions [0, 1, 2, 3, 4].
The global atlas describes planning vocabulary and does not itself certify a definition or theorem. The reviewed expansion and conservative dependency DAG on this page are the actual family-local reading definitions.
