Open source
Identity, credentials, runtime, and audit are inspectable before approval and verifiable after deployment. Open code is part of the evidence—not a substitute for it.

Your security team can read the source for the components that run in your perimeter, build them from that source, and verify that the deployment matches what was reviewed. Approval rests on evidence, not on a vendor questionnaire — the same standard the rest of the stack holds itself to.
Install an autonomous software factory that plans, builds, tests, deploys, and maintains software inside your network, under your controls.
