+# Judge Checklist — COS™ Blockchain Compliance Tracker
+
+This checklist provides a reference for verifying the reproducibility and ethics‑first commitments of the COS™ Blockchain Compliance Tracker submission.
+
+---
+
+## ✅ Setup
+The setup process involves cloning the repository, installing dependencies, and configuring environment variables.
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/cmacademyconsulting/COS-Blockchain-Compliance-Tracker.git
+   cd COS-Blockchain-Compliance-Tracker
+Install dependencies:
+
+bash
+npm install
+Configure environment:
+
+Copy .env.example to .env.
+
+Add Infura Project ID and DKG Edge Node URL.
+
+Ensure wallet keys are configured for Westend/Paseo testnets.
+
+🚀 Demo Verification
+The demo scripts illustrate how governance events are logged and verified.
+
+Run demo script:
+
+bash
+npm run demo
+Outputs governance events, SHA‑256 hashes, and blockchain Tx IDs.
+
+Fallback demo (plain‑text):
+
+bash
+npm run demo:plain
+Provides simplified outputs for universal compatibility.
+
+Tx ID verification:
+
+Open https://polkadot.js.org/apps (Westend/Paseo).
+
+Paste a Tx ID from /appendix/audit_table.csv.
+
+Block number and account can be checked against demo output.
+
+📊 DKG Integration
+These scripts demonstrate publishing and querying compliance notes in the OriginTrail DKG.
+
+Publish compliance notes:
+
+bash
+node src/dkg_publish.js
+Converts governance events into JSON‑LD/RDF Knowledge Assets with provenance metadata.
+
+Query compliance notes:
+
+bash
+node src/mcp_query.js
+MCP agents query published notes for ESG verification.
+
+Compute reputation scores:
+
+bash
+node src/reputation_score.js
+Oversight logs mapped into reputation scores, published to DKG for querying.
+
+🎥 Demo Video
+The demo video illustrates the flow: Governance event → Tx ID → DKG note → Reputation score → Dashboard view.
+
+⚖️ Ethics‑First Commitments

+# 🏛️ COS™ Governance Framework — Compliance, Oversight, Sustainability
+
+This document defines the tri‑pillar governance framework of the COS™ Blockchain Compliance Tracker.  
+It operationalizes ethics‑first governance by embedding compliance, oversight, and sustainability into blockchain and OriginTrail DKG workflows, ensuring transparency, accountability, and reproducibility.
+
+---
+
+## Pillar 1 — Compliance
+- **Audit‑Ready Documentation:** Standards aligned with CMAA, FIDIC, ISO, and donor requirements.  
+- **Immutable Proofs:** Each compliance event hashed and logged on‑chain with verifiable TxIDs (Sepolia testnet, confirmed via Etherscan).  
+- **Reproducibility Link:** TxIDs documented in `/appendix/audit_table.csv` for judge verification.  
+- **Dashboard Integration:** Compliance metrics displayed in real time for donors and managers.  
+**Ethics Impact:** Ensures every compliance claim is backed by cryptographic proof.  
+
+---
+
+## Pillar 2 — Oversight
+- **Ethical Supervision:** Oversight ensures worker safety, duty of care, and governance integrity.  
+- **Traceability:** Oversight activities linked to TxIDs, ensuring accountability of auditors and contractors.  
+- **Transparency:** Incident reports and corrective actions published as verifiable Knowledge Assets.  
+- **Reproducibility Link:** Demo scripts (`src/reputation_score.js`) illustrate accountability scoring.  
+**Ethics Impact:** Builds accountability by exposing negligence and rewarding ethical behavior.  
+
+---
+
+## Pillar 3 — Sustainability
+- **ESG Metrics:** Environmental, social, and governance indicators aggregated into a Sustainability Index.  
+- **Climate Resilience:** Projects designed with long‑term sustainability and community impact in mind.  
+- **Donor Confidence:** Sustainability claims backed by immutable blockchain records.  
+- **Community Assurance:** Communities gain trust in ethical and sustainable project delivery.  
+**Ethics Impact:** Guarantees that sustainability claims are verifiable and trusted.  
+
+---
+
+## Integration with OriginTrail DKG
+- **Knowledge Assets:** Compliance, oversight, and sustainability events published in JSON‑LD/RDF with provenance.  
+- **MCP Agents:** Query Knowledge Assets to validate AI outputs against human‑curated facts.  
+- **Trusted Feeds:** Governance dashboards powered by DKG data, enabling verifiable transparency.
