Summary
We retain duplicate binding and declaration lists because reachable histories include implicit unbound/undeclared entries that end-of-scope histories can discard. We now store those initial entries as one reachability constraint per place and intern the remaining definitions, reusing the corresponding end-of-scope declaration list when it matches.
