   > satisfied by a countable, rulial structure (the Signal-Reals).   
   >   
   > Cardinality Result: This result establishes CCH for the unit interval:   
   > ∣[0,1]∣=∣N∣=ℵ0​. This is the core achievement of the A-Theory's   
   > axiomless natural deduction.

   > 🧱 Extension to the Real Line: The Bookkeeping Problem   
   >   
   > The extension from the unit segment [0,1] to the entire real line R

   > transitive associativity of cardinality.

   > countable union of countable sets (the unit segments). The resulting

   ∣R∣>ℵ0​.
