Lab & Proofs
Evidence before confidence.
The lab is where architecture stops winning by elegance. Claims are bounded, proof contracts are frozen, negative evidence is preserved, and systems are exposed to replay, mutations, invalid states, and adversarial challenge.
Evidence discipline
A passing test is only as strong as the claim it was designed to test.
The lab distinguishes internal validation, executable reference proof, live integration evidence, independent reproduction, runtime evidence, and longitudinal reliability. Those evidence classes are not interchangeable.
A core rule is simple: the claim ceiling should never rise above the weakest load-bearing evidence, authority, dependency, or independence condition.
Frozen proof contracts
Define the claim, denominator, validators, stopping rules, and disposition logic before material results are exposed.
Negative controls
Demonstrate that the harness can detect failure rather than merely report universal success.
Replay
Verify that equivalent inputs reproduce normalized governed outcomes.
Adversarial mutations
Inject invalid states, authority failures, stale dependencies, and boundary conditions intentionally.
Independent assurance
Separate implementation and adjudication lineage where a stronger assurance claim requires it.
Claim ceilings
State exactly what the evidence establishes—and what it does not.
