The Cost of Certification
Manual DO-178C certification for aerospace software costs $1M+ per project and takes 6-12 months. IEC 62304 for medical devices is similarly expensive. ISO 26262 for automotive adds another layer of complexity. These certifications are absolutely necessary — when a bug can kill a person, you need mathematical proof that it will not happen.
But here is the cruel irony: the cost is so prohibitive that most companies cannot afford to do it properly. A startup building a medical device or a drone controller cannot justify $1M for certification. The result is devastating: most safety-critical software in the world relies on testing instead of proof. And people die because of it. Not hypothetically. Actually.
Verification Evidence at Compile Time
BRIK64 changes this equation completely. It generates structured review evidence during the build flow, at compile time, at with less separate evidence-preparation work. Every function that compiles with Phi C = 1 produces a certificate that documents:
Input domain bounds: Every parameter has a declared range. Values outside the range are rejected at compile time. An insulin pump cannot receive a dose of -5 or 500. The compiler prevents it.
Exhaustive coverage: Every execution path has a defined output. No undefined behavior. No "this should never happen" that happens at 3 AM in an ICU.
Deterministic execution: Same input always produces same output. No randomness, no side effects. The flight computer produces the same answer on every run, every time, on every hardware platform.
type Dose = range[0.0, 25.0];
// insulin units
type Glucose = range[20, 600];
// mg/dL
fn calculate_dose(glucose: Glucose, weight: range[1, 300]) {
// Overdose is structurally outside the declared model.
// The domain rejects any dose > 25.0 at compile time.
// Φc = 1: every input produces a valid, bounded output. }Industries Aerospace (DO-178C): Flight controllers, navigation systems, engine control units. Mathematical evidence that every combination of velocity, altitude, and fuel state produces a defined, safe response. Not tested — proven.
Medical devices (IEC 62304): Insulin pumps, infusion controllers, diagnostic algorithms. Mathematical evidence that overdose is structurally outside the declared model. The domain constraint makes it a compile-time error, not a patient safety incident.
Automotive (ISO 26262): Autonomous braking, collision avoidance, speed limiting. Mathematical evidence that every distance measurement has a defined braking response. No undefined behavior at 120 km/h.
Robotics (ISO 10218): Collaborative robots working alongside humans. Mathematical evidence that the robot cannot exceed safe speed when a human is detected nearby. The circuit enforces it — not a software flag that can be overridden.
The ROI
Manual certification: $1M+ and 6-12 months of painstaking documentation. BRIK64 formal verification: automatic, at compile time, every time you build. a more explicit evidence path. With a clearer review surface and less manual reconstruction. This is not about cutting corners — it is about making safety accessible to every company that builds software where lives are at stake.
