I'm building Calybris, a decision engine in Rust that logs why it chose what it chose. The open-source core is on GitHub.

My focus is on systems where decisions need to be traceable and reproducible — AI model routing, cost governance, analytical pipelines. Still early stage, learning in public.

00 Core Engine

Calybris Engine

Proof-carrying, domain-neutral prescriptive decision engine. Rust. Every decision gets a fingerprint, cost estimate, risk penalty, quality floor, and replayable audit trail.

GOVERIS

AI cost governance gateway. Every LLM call must justify its cost. Routes, downgrades, blocks, caches across OpenAI · Anthropic · Google based on expected value, risk, confidence, and tenant budget.

Rust Quant Audit MDL

LuceThemis

Quant signal evidence audit layer. Not a trading bot — a falsification engine. Tests whether signals survive cost, leakage, overfit, walk-forward, and complexity pressure before capital goes in. MDL-inspired proxy: more complex signal requires stronger evidence.
