# Cross-Model Verification
A second model catches what the first is blind to only if it is independent.
Independence has two parts: the verifier comes from a different vendor than the
author, and it never sees the author's reasoning or conclusion. A verifier that
sees the prior conclusion anchors to it and confirms; a blind verifier keeps its
edge.
## Prefer an oracle to an opinion
Before asking a model, ask whether an executable check can decide it: tests,
types, a compile, a property test, a reproduction. An oracle is deterministic
and not fooled by a confident argument. Reserve model verification for what no
oracle covers: design soundness, subtle logic, security reasoning, "does this
actually do what it claims".
## Procedure
1. **Launch a verifier with the author vendor declared** via
multi-agent-delegation's `scripts/delegate-run --role verify
--author-vendor VENDOR --artifact ... --claim ...`. The resolver fails if it
cannot route away from every declared author vendor. A second
instance of the same model shares the same blind spots, and self-preference
bias is largest when a model judges its own family's output
(arXiv 2410.21819).
2. **Hand over the artifact and the claim, nothing else.** The verifier gets the
diff, code, or document plus a crisp statement of what it is supposed to do
or guarantee. Withhold the author's chain-of-thought, self-review, and
justification. Information restriction is the point.
3. **Prompt it to refute, wit
