monora 1.9.2

Lightweight governance and trace SDK for AI systems

Monora v1.9 SDK

Lightweight governance and trace SDK for AI systems

Monora provides minimal viable trust through immutable event logs, policy enforcement, and comprehensive auditability for LLM applications.

Features

• 🔒 Immutable Event Logs: Cryptographic hash chains for tamper detection
• 📋 Policy Enforcement: Model allowlists/denylists with data classification controls
• 🧭 Provider Registry: Explicit model-to-provider mapping with unknown-model alerts
• 🧾 Versioned Registry: Registry versioning, history, and provider deprecation metadata
• 🔍 Full Auditability: JSON-lines event logs with CLI reporting tools
• 📎 Auto Reports: Compliance artifacts generated at trace completion with trust summaries
• 📦 Trust Packages: One-shot vendor export with compliance, config snapshot, and hash-chain proof
• ⚡ Non-blocking: Background worker with bounded queue for zero user-code latency
• 🎯 Simple API: Decorator-based interface with sensible defaults
• 🧩 Auto-Instrumentation: Optional OpenAI/Anthropic patching for drop-in logging
• ✅ Completeness Checks: Event sequencing and security review reports
• 🔌 Pluggable Sinks: Stdout, file, and HTTPS endpoints
• 🚨 Violation Alerts: Callback or webhook notifications for policy violations
• 🧹 Data Handling: Regex redaction rules tied to data classifications
• 🛡️ Signed Attestations: Optional GPG-signed security review bundles

New in v1.9.0

• 🔄 Circuit Breaker: Fault tolerance for HTTPS sinks with automatic recovery
• 📊 Telemetry/Analytics: Prometheus and StatsD metrics export for observability
• 📄 PDF Reports: Generate compliance and EU AI Act PDF reports
• 🌐 Django Middleware: W3C Trace Context propagation for Django applications

Installation

pip install -e .

# With YAML config support
pip install -e ".[yaml]"

# With HTTPS sink support
pip install -e ".[https]"

# Development dependencies
pip install -e ".[dev]"

Quick Start

Minimal Example (Dev Mode)

import monora

# Initialize with defaults (stdout logging, no policies)
monora.init()

@monora.llm_call(purpose="customer_support")
def ask_gpt(prompt: str, model: str = "gpt-4o-mini"):
    # Your LLM call here
    return {"response": "Hello!"}

# Use trace context for grouping events
with monora.trace("ticket_123"):
    response = ask_gpt("How do I reset my password?")

Guided Setup (Wizard)

monora init

This generates a monora.yml you can edit and pass to monora.init(config_path="monora.yml").

Validate & Diagnose

monora validate --config monora.yml
monora doctor --config monora.yml

Export Vendor Trust Package

trust_package = monora.export_trust_package(
    trace_id="trace-123",
    input_path="events.jsonl",
    config_path="monora.yml",
)

See README.md for full documentation and examples.

v1.9.0 Features

Circuit Breaker

Prevent cascading failures with circuit breaker pattern for HTTPS sinks:

sinks:
  - type: https
    endpoint: https://api.example.com/events
    circuit_breaker:
      enabled: true
      failure_threshold: 5
      success_threshold: 2
      reset_timeout_sec: 60

Telemetry/Analytics

Export metrics to Prometheus or StatsD:

import monora

# Configure telemetry
monora.init(config={
    "telemetry": {
        "enabled": True,
        "backend": "prometheus",  # or "statsd"
        "prometheus": {
            "port": 9090,
            "start_server": True
        }
    }
})

# Metrics are automatically recorded:
# - monora_events_total (by event_type)
# - monora_violations_total (by policy_type)
# - monora_queue_depth
# - monora_tokens_total

PDF Report Generation

Generate compliance PDF reports:

from monora import generate_compliance_pdf, generate_ai_act_pdf

# Generate compliance PDF
generate_compliance_pdf(
    report=compliance_report,
    output_path="compliance_report.pdf"
)

# Generate EU AI Act transparency PDF
generate_ai_act_pdf(
    report=ai_act_report,
    output_path="ai_act_report.pdf"
)

Requires optional dependency: pip install weasyprint

Django Middleware

Automatic W3C Trace Context propagation for Django:

# settings.py
MIDDLEWARE = [
    'monora.middleware.django.MonoraDjangoMiddleware',
    # ... other middleware
]

# Optional configuration
MONORA_MIDDLEWARE = {
    'skip_paths': ['/health', '/ready'],
}

For async ASGI deployments:

MIDDLEWARE = [
    'monora.middleware.django.MonoraDjangoAsyncMiddleware',
    # ...
]

Testing
