   You're assuming 'truth in arithmetic' means truth-in-the-standard-model.   
   But that's a meta-theoretic construct—it's truth about arithmetic from   
   outside PA, not truth in arithmetic. PA has no internal truth predicate   
   and no way to access the standard model from within.   
      
   When you say 'truth goes beyond knowledge,' you're really saying   
   'meta-theoretic truth goes beyond PA-provability.' That's trivially   
   correct, but it doesn't establish that Gödel sentences are 'true in   
   arithmetic'—it just shows they're true in a meta-theoretic framework   
   we're smuggling in and calling 'arithmetic.'   
      
   The question isn't whether meta-theoretic truth transcends provability.   
   It's whether meta-theoretic truth has any claim to being genuinely   
   arithmetical truth, or whether it's a confusion of levels that's been   
   normalized for a century.

              My 28 year goal has been to make
       "true on the basis of meaning expressed in language"
       reliably computable.

              This required establishing a new foundation
