coreason-validator 0.4.0

Enforces structural integrity across the entire CoReason ecosystem

coreason-validator

Enforces structural integrity across the entire CoReason ecosystem.

Overview

coreason-validator acts as the Single Source of Truth for all data structures (Agents, Tests, Topologies, Messages). It provides "Schemas-as-Code" definitions and validation logic to check assets before they are processed, ensuring structural soundness.

In a GxP environment, "Implicit Trust" is a vulnerability. Component A must never assume Component B sent valid data. This library ensures that what is about to happen is structurally sound.

Key Features

• Schema Registry: A collection of immutable Pydantic Models defining valid assets.
• Static Analyzer: A validation engine that runs on static files (JSON/YAML) with rich error reporting.
• Runtime Guard: A lightweight validation function for dynamic payloads with microsecond latency.
• Integrity Hasher: Provides canonical hashing to ensure file integrity and GxP compliance.
• Frontend Bridge: Exports JSON Schemas to keep the UI in sync with the backend.

Architecture

The library implements the Define-Check-Hash Loop:

1. Define: Schemas as strict Python classes (Pydantic V2).
2. Check: Shift-left validation locally and at runtime.
3. Hash: Canonical hashing of the validated structure for GxP integrity.

See Architecture for more details.

Getting Started

Prerequisites

• Python 3.12+
• Poetry

Installation

1. Clone the repository:

   git clone https://github.com/CoReason-AI/coreason_validator.git
   cd coreason_validator
   

2. Install dependencies:

   poetry install
   

Usage

CLI Quick Start

The package exposes a CLI tool coreason-val for validation and schema operations.

Validate a File

To validate a YAML or JSON file against its schema (schema type is auto-detected):

poetry run coreason-val check path/to/file.yaml

Example:

poetry run coreason-val check samples/agent_config.yaml

Export JSON Schemas

To export the canonical JSON Schemas for use in other systems (e.g., Frontend forms):

poetry run coreason-val export ./schemas_out

This will generate agent.schema.json, bec.schema.json, etc., in the specified directory.

Python API

For deep integration, import coreason_validator directly.

from coreason_validator import validate_file, validate_object

# Validate a file
result = validate_file("path/to/agent.yaml")
if result.is_valid:
    print("Valid!")
else:
    print(f"Errors: {result.errors}")

# Validate an object (Runtime)
data = {"name": "my-agent", "version": "1.0.0"}
try:
    model = validate_object(data, "agent")
    print(f"Canonical Hash: {model.canonical_hash()}")
except Exception as e:
    print(f"Validation failed: {e}")
