There was a problem hiding this comment. BLOCKING: connective_is_kernel_ambient_atom is a new Bool predicate over the Connective coproduct with no Practice-10 disposition tag or DECISIONS receipt, violating predicate-dissolution discipline. |

BLOCKING: named_fact_count directly matches EdgeLabel instead of consuming std/node.dag's declared edge_is_named query, so the lens re-derives lower-layer storage shape and violates INVARIANTS P2/L-7 single-authority boundary discipline.
