Abstract Some truths are hard to discover and easy to verify. A factorization, once found, can be checked quickly. A proof, once written, can often be verified more easily than it was discovered. A biological intervention, once stabilized, can look retrospectively obvious even though the admissible functional corridor was narrow and difficult to locate in advance. This paper examines that asymmetry. Its central claim is that generation and verification are structurally different tasks, and that the difference is often governed by a prior regime. Verification presupposes that the object being checked, the property being checked, and the admissible transformation or witness relation have already been sufficiently stabilized. Where those conditions are absent, “verification” can become shallow, local, or misapplied. Where they are present, an object that was difficult to find may become cheap to certify once presented. The paper does not claim to solve discovery in general, reduce all domains to one formalism, or extend the formal identity-persistence theorem. It is a companion argument inside the broader identity-persistence program. Its narrower aim is to show that many cases of retrospective obviousness arise when a lawful corridor is narrow in search but cheap in verification once the regime and witness relation are in place. The result is a regime-first account of discovery asymmetry across formal proof, cryptography, zero-knowledge certification, biological persistence, and regime-bound computational search.
