When you compute a drug dose, a patient metric, or a clinical prediction, traditional code gives you a single number with no context. Sounio automatically tracks measurement error, ISO GUM uncertainty, and data provenance through every step of execution.
Featured: Vancomycin dosing that cannot lie about uncertainty.
Sounio is a systems programming language for scientific teams that need to reason not only about values, but about trust, provenance, and uncertainty at every stage of execution.

EPISTEMIC SYSTEMS LANGUAGE
A programming language that carries
what it doesn't know.
Not a workaround. A type.
fn dose_vancomycin(auc: Knowledge<f64>) -> f64
where auc.ε >= 0.82
{
auc.value / 24.0
}
// caller — ε = 0.71, below threshold:
let measured = Knowledge { value: 430.0, ε: 0.71 };
dose_vancomycin(measured);Not a heuristic. Not a warning. The type checker sees ε = 0.71, the signature requires ε ≥ 0.82, and the program does not compile. The contract is in the type.

The language turned its uncertainty system on itself. Across eight bootstrap generations, the compiler tracked its own confidence through every expression. At generation eight: 113,931 expressions. All certain. Guard overhead: zero bytes. The binary proved it by compiling itself twice to the same hash.
md5(gen₂.elf) = md5(gen₃.elf) · 15,636 call sites · 0 guarded · 1.25 MB
Three compile-time type disciplines no other language has as first-class primitives. Each enforced at every call site. Each formally specified.

PHARMACOKINETICS
14-compartment PBPK · Cayley-Dickson transfer dynamics · GUM-exact ODE
Each sedenion basis element encodes one anatomical compartment. Drug transfer between tissues is Cayley-Dickson multiplication — the algebra is the pharmacokinetics.

31 modules · PDG uncertainties at every vertex · LO QED ±2% vs CERN data
The 18 Standard Model parameters carry their PDG uncertainties as Knowledge<f64>. The type checker enforces error budgets through every Feynman amplitude.

Linear-typed qubits · Bell pairs · VQE H₂ ground state · compile-time no-copy
Linear types make quantum cloning a compile error. No runtime check. No convention. The no-cloning theorem is a constraint on the type of Qubit.

44 SI base + derived units · dimensional analysis at compile time · 100+ PK variables typed
Physical units are first-class types. Dimensional mismatches are compile errors. A 100-variable PBPK model carries its full unit type at every step.

Linear-typed ε · Laplace mechanism · GUM Type-B noise folded with genomic uncertainty
The privacy budget ε is a linear type — the compiler prevents double consumption. Noise folds into GUM uncertainty; both are tracked in the same type.

AlphaGeoZero · Beta-distributed solution confidence · first geometry prover with ε
AlphaGeoZero proves IMO geometry problems and reports per-problem confidence as a Beta distribution — the first geometry prover that quantifies its own uncertainty.

souc is written in Sounio and bootstrapped through three stages. Stage 2 and Stage 3 binaries are SHA-256 identical — the fixed-point is the proof.
