Calybris Core is a deterministic proof-carrying decision core designed for systems that require transparent justification and replay capabilities for decision-making processes. Unlike traditional models or strategy engines, Calybris Core functions as a domain-neutral decision primitive that focuses on providing reliable, verifiable outcomes based on specified constraints.

The core decision process transforms inputs into actionable decisions through a defined relationship between candidates and policy constraints:

candidate + policy constraints → decision + digests + optional WAL + budget proof

Key Use Cases

1. LLM Routing: Efficiently select, substitute, or reject models based on budgetary, risk, quality, and latency criteria.
2. Pre-Trade Guard: Assess and decide on candidate orders, ensuring limits on exposure, risk, and latency are adhered to before finalizing decisions.

Calybris Core serves as the underlying deterministic pre-trade decision kernel, facilitating clear integer-only constraints while incorporating features such as replay verification and fixed-point conservation proofs.

Features

• Deterministic Decision Making: Ensure consistent decision-making by maintaining the ability to reproduce outcomes reliably.
• Replay Verification: Validates that decisions can be audited and reconstructed accurately.
• Tamper-Evident Audit Log: Secures decision records with a hash chain that protects data integrity.
• Fixed-Point Budget Proofs: Offers assurance of budget management and compliance during operations.

Functionality Overview

Calybris Core is ideal for applications requiring consistent decision-making across various inputs and constraints. It should not be used as a hosted API or trading strategy but rather serves as a critical component within larger systems. Whether routing requests based on specific criteria or guarding against overspending in financial applications, Calybris provides a robust and secure core for strategic decision-making.
