//! Negative capability — proofs of structural impossibility.
//!
//! The negative module provides:
//! - Proofs that an agent CANNOT do something (by structure, not policy)
//! - Ceiling-based impossibility (not in capabilities ceiling)
//! - Lineage-based impossibility (no ancestor has capability)
//! - Spawn exclusion proofs (explicitly excluded at spawn)
//! - Voluntary negative declarations (self-imposed restrictions)
//! - Verification of negative proofs
