Use `isDead()` when printing + or filtering dead nodes; an empty input array alone does not imply death. + Bounds-safe edge inspection only needs null-node and input-count checks. + - Type construction and interning are allowed during printing. Do not add alternate linker-key comparisons or other machinery merely to avoid interning; canonical types and fast identity comparisons are normal type-system operations. |
