Locate Lt in the global campaign vocabulary →
Reviewed Lt corresponds to blueprint Lt with checked argument positions [0, 1].
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.
