Theorem · version 2
If P = NP, then every polynomially balanced, polynomial-time-decidable witness relation admits polynomial-time witness search or correct reporting that no witness exists.
An asymptotic search consequence for these relations; output length and encoding restrictions matter.

Conditional implication · Proved
This statement contributes context in its stated scope; it does not settle the canonical P versus NP question.
This is one indexed assertion in its own scope. No disjoint solved fraction, strongest-known ranking or additional parent resolution is inferred.
Relationship not independently reviewed. This concerns its use in this problem.
