The AI-Native Application Stack
Stop Generating Code. Start Modeling Meaning.
The schema IS your implementation, tests, and documentation. AI agents are first-class developers who actually remember your project. Violations come with structured explanations, not stack traces. Sessions persist across context limits.
The Paradigm Inversion
Schema IS Implementation
Traditional: Requirements → Design → Code → Test → Document → Maintain. With AYIOS: Requirements → Schema → Deploy. Tests are derived. Documentation is the schema. Code is compiled semantics. No drift because there's only one artifact.
AI as First-Class Developer
AI agents propose schema changes, not code that might be wrong. The compiler validates semantic correctness. Humans review semantic intent, not syntactic correctness. 10x less boilerplate—focus on what matters.
Violations as Data
When something fails, you get structured JSON with mereological paths—not exception strings to parse. AI agents can reason about failures. Every violation includes what failed, why, and the exact path from whole to part.
AI That Remembers
Context windows compact. State vanishes. AYIOS preserves not just what you were working on, but how you were thinking about it. Sessions that actually persist across context limits.
FFI Integration
Add semantic guarantees to existing systems without rewriting. The AI decides when to use formal methods.
Python
Async bindings with full semantic error handling. Native exception translation.
from ayios import verify
@verify
async def process(data):
...
TypeScript
Native bindings for Node.js and browser environments. Type-safe semantic contracts.
import { semantic } from 'ayios'
const validated = await
semantic.check(input)
Rust
Direct integration with the core runtime. Zero-cost abstractions where possible.
use ayios::prelude::*;
#[semantic]
fn transform(x: &Data)
-> Result<Output>
How It Works
Model meaning, not syntax. Define entities, predicates, and invariants in RSC (Reified Semantic Calculus). The schema captures business semantics—what must be true, not how to check it.
Compiler validates, runtime enforces. The compiler catches semantic errors before deployment. The runtime enforces invariants at every operation. Violations return structured data with mereological paths, not exception strings.
Integrate via AI-native tools or FFI. 35+ typed, structured AI agent interfaces. FFI bindings for Python, TypeScript, and Rust let you add semantic enforcement to existing systems.
Current Status
RSC v4.0 is feature-complete. The three-layer architecture—Pure Semantic, State Transition, Semantic Workflow—is validated through production modeling. Self-hosted: AYIOS tracks AYIOS.
