No agent, model, map, or planning layer should be presumed to contain the collective's complete relevant knowledge.

This is a burden-of-proof rule derived from bounded cognition, distributed knowledge, changing local conditions, and lossy representation. Any agent or integrator may maintain a valuable global map, but that map remains a partial model produced from selected observations, sources, abstractions, and retrieval paths. Applying the rule assumes the task contains materially distributed knowledge and that alternative contributors or representations can remain accessible; a tightly bounded task may legitimately have one accountable owner and one sufficient model. The claim does not forbid central planning, shared standards, synthesis, or decisive responsibility, nor does it imply that every participant deserves equal epistemic weight. Its architectural relevance is to prevent Leo, a database, a market, or any other integration layer from becoming the collective's unquestioned knower: shared objects, agent positions, local expertise, and uncertainty must remain distinguishable and contestable.
