- <p>Abstract<br>The CKS pattern's determinism contract commits a substrate to five guarantees about reproducibility<br>and bounds the non-determinism the architecture permits at the model and operational layers.<br>Companion decomposition notes formalize the substrate/model boundary, the five guarantees<br>individually, and the allowed non-determinism. What remains to formalize is the operational<br>verification mechanism: without it, the contract is aspirational — guarantees declared but not<br>checkable. This note formalizes regression testing as having independent architectural content. The<br>commitment is to operational feasibility — substrate state can be fixed, orchestration rules can be fixed,<br>operations can be executed, and the guarantees can be verified — distinct from the deployment-level<br>practice of running specific tests, maintaining test suites, or integrating tests into pipelines. The note<br>states the four operational components the architecture must satisfy, specifies how the test mechanism<br>accommodates the five categories of allowed non-determinism, distinguishes the commitment from<br>four adjacent verification patterns commonly conflated with it, names ten failure modes that violate it,<br>and provides an operational test for whether a given system's regression-testing architecture satisfies<br>the commitment.</p>
