ReadonlyembedReadonlylogitsThe target's output head per row count or range: the drafter indexes it by the rows it projects. Borrows the hidden; the logits belong to the caller.
Optional ReadonlyvocabularyDeclared by a graph whose composition measured a drafter selecting over the target's frequency-ranked draft vocabulary: its ids [N] (ascending, uint32, borrowed) and the head's projection onto those rows per row count or range (logits [..., N], caller-owned). A drafter that selects by its scores alone selects over these rows; the target still verifies over its full head. Absent: the full head.
Numerical ports are backend-specific; returned arrays are caller-owned.
