+# Triumph Synergy Digital Financial Ecosystem — Integration
+
+**Repository:** https://github.com/jdrains110-beep/Triumph-Synergy-Digital-Financial-Ecosystem  
+**Image used:** `pinetwork/pi-node-docker:organization-mainnet-v1.0-p23.0.1`  
+**Node role:** Sovereign on-chain anchor (replaces third-party API endpoints)
+
+## Overview
+
+The Triumph Synergy Digital Financial Ecosystem runs `pi-node-docker` as
+its **primary sovereign Pi mainnet node**. All payment rails, settlement,
+tokenization, and payroll flows settle against this self-hosted node
+rather than a third-party API, ensuring full sovereign control.
+
+Services that depend on this node:
+
+| Service | Port | Role |
+|---------|------|------|
+| pi-bridge-connector | 8092 | Pi Network bridge |
+| settlement-core | 8080 | T+0 settlement |
+| tokenization-engine | 8085 | Asset tokenization |
+| sovereign-work-nexus | 8132 | Global jobs + Pi payroll |
+| publix-phygital-hub | 8133 | Phygital retail Pi payments |

+
+## Upgrade notes
+
+Before upgrading to a new image version, stop the container and snapshot
+the `pi_mainnet_stellar` Docker volume (pg_upgrade rewrites in place).
+Per the v1.0-p23.0.1 release notes: back up volumes before upgrading,
+do not interrupt the first boot while `pg_upgrade` and migrations run.
