**BITC (Blue Intelligence Technologies Corporation)** is an open-source technical trust and algorithmic auditing framework designed specifically for African public institutions, regulators, and research organizations.

It operationalizes the **African Union Continental Artificial Intelligence Strategy (2024)** and the **UNESCO Recommendation on the Ethics of Artificial Intelligence (2021)** by providing verifiable tools to inspect, evaluate, and continuously monitor automated decision systems deployed in public services.

## 🏛️ Key Objectives

1. **Digital AI Passport**: A cryptographic, tamper-evident manifest detailing training data provenance, intended operational domain, known limitations, and legal accountability.
2. **Contextual Algorithmic Auditing**: Automated testing for demographic parity, disparate impact, and representational bias across African linguistic and ethnic groups.
3. **Data Sovereignty Compliance**: Verifying local data locality, non-export agreements, and adherence to national data protection legislation and the Malabo Convention.
4. **Continuous Telemetry & Drift Monitoring**: Post-deployment tracking of concept drift, adversarial evasion attempts, and degradation in algorithmic reliability.

## 🚀 Quickstart: Generating an AI Passport

```bash
# Clone the repository
git clone https://github.com/sks-governance/bitc-ai-trust-framework.git
cd bitc-ai-trust-framework

# Inspect the AI Passport schema
cat schemas/ai-passport-schema.json | jq .

# Run the fairness evaluation engine
python core/bias_audit_sample.py --dataset test_public_service.csv --target-col decision
```
