Context
Trusted AI · requirements, testing, code generation
When code starts writing itself, proof matters more — not less.
AI can accelerate requirements, testing and code generation. The resulting artifacts still need independent verification, traceability and audit-grade reports before they belong inside a brake system, a pacemaker or a train control loop. BTC TestStack grounds new code sources in the same formal process safety-critical teams already trust.
