 ### When to optimistically import blocks
 
 A block MAY be optimistically imported when
-`should_optimistically_import_block(opt_store, current_slot, block)` returns
+`is_optimistic_candidate_block(opt_store, current_slot, block)` returns
 `True`. This ensures that blocks are only optimistically imported if either:
 
 1. The justified checkpoint has execution enabled.
