    // (weak_debate, composite_mismatch), unknown-enum (unknown_role),
    // or multi-block (duplicate_ship) setups whose isolation behavior
    // depends on parser invariants the harness should not duplicate.
    // Marking them it.todo documents the gap explicitly so the next
    // contributor finishing the matrix sees what's missing rather than
    // assuming the kind is uncovered by accident.
