+     ```
+   - **Tech Rationale:** 
+     - *Why MinIO*: local sovereignty + S3 compatibility.
+     - *Why Argo*: lightweight orchestration vs Airflow.
+     - *Why Supabase/PostGIS*: fast Postgres + PostGIS integration for spatial depth.
+
+2. **Infrastructure Design (K3s Sovereign Cluster)**
+   - **Title:** Infrastructure Design (K3s Sovereign Cluster)
+   - **Visual:** Cluster design details (Single-node K3s on Contabo VPS).
+   - **Resource Strategy:** 512MB limits for API/Web; 2GB for Worker/Jupyter.
+   - **Key Principle:** “Designed for low-resource environments while maintaining full MLOps capability.”
+   - **Terraform Layer:** Namespace isolation (geocrop), Resource quotas, Future SSO integration.
+   - **GitOps Layer:** Argo CD as single source of truth (/k8s/base + /overlays). “Everything deployed is version-controlled and reproducible.”
+
+3. **End-to-End MLOps Workflow**
+   - **Title:** End-to-End MLOps Workflow
+   - **Pipeline Breakdown:**
+     1. **Data Ingestion:** Zimbabwe CSV batches stored in MinIO.
+     2. **Training:** Triggered via Argo Workflows, executed from `/training/active`.
+     3. **Experiment Tracking:** MLflow logs parameters, metrics, and artifacts.
+     4. **Deployment:** Model packaged into worker container, deployed via Argo CD.
+
+4. **Engineering Decisions & Trade-offs (CRITICAL)**
+   - **Title:** Engineering Decisions & Trade-offs
+   - **Argo vs Kubeflow**: 
+     - *Decision*: Chose Argo Workflows + Argo CD.
+     - *Why NOT Kubeflow*: Too resource-heavy for 512MB constraints; complex deployment overhead.
+     - *Why Argo*: Lightweight, native K8s integration, easier GitOps alignment.
+   - **Gitea vs GitLab**:
+     - *Decision*: Chose Gitea.
+     - *Why NOT GitLab*: High RAM usage; overkill for single-node cluster.
+     - *Why Gitea*: Lightweight, self-hostable in constrained environments, good enough CI/CD via Actions.
+   - **MLflow vs Alternatives**: Simple experiment tracking, easy DB backend integration (Postgres), lightweight vs full ML platforms.
+   - **MinIO vs Cloud Storage**: Full data sovereignty, S3-compatible, works offline / low-connectivity environments.
+   - **Supabase (Postgres + PostGIS)**: Spatial queries (critical for geospatial ML), simple API layer, lightweight vs full GIS stacks.
+
+5. **Observability & Monitoring**
+   - **Title:** Observability & System Monitoring
+   - **Stack:** Prometheus (Metrics), Grafana (Visualization), Uptime Kuma (SLA monitoring).
+   - **Live Endpoints:** uptime.techarvest.co.zw, grafana.techarvest.co.zw, prometheus.techarvest.co.zw.
+   - **Metrics:** API latency, container health, resource usage, job execution success.
+
+6. **Live System Page**
+   - **Title:** Live Infrastructure (Production System)
+   - **Status Table:**
+     | Service | Status |

+# Restructuring Report: GeoCrop Sovereign MLOps Platform
+
+This document summarizes the end-to-end transformation of the GeoCrop project into a professional, GitOps-driven MLOps platform on K3s.
+
+## 1. Foundation & Backup
+- **Image Migration**: Identified 31 unique container images running in the cluster. Systematically pulled, re-tagged, and uploaded them to the `frankchine/` repository on Docker Hub to ensure local ownership of all dependencies.
+- **Project Renaming**: Transitioned from a simple application folder to a unified monorepo structure ready for professional portfolio showcase.
+
+## 2. Infrastructure as Code (Phase 1)
+- **Terraform Management**: Established Terraform as the authority for cluster namespaces (`geocrop`, `argocd`).
+- **Gitea Deployment**: Launched a self-hosted Gitea instance (`git.techarvest.co.zw`) as the central source of truth and CI/CD hub.
+- **Database Isolation**: Replaced the heavy Supabase stack with a lightweight standalone **PostGIS** instance on port **5433**, ensuring low RAM usage and full spatial capabilities.
+- **MLOps Tooling**: 
+    - **MLflow**: Live at `ml.techarvest.co.zw`, connected to PostGIS for experiment tracking.
+    - **JupyterLab**: Live at `lab.techarvest.co.zw` with 20Gi persistent storage for interactive data science.
+- **GitOps Orchestration**: Deployed **ArgoCD** to manage the lifecycle of all services via Git.
+
+## 3. Frontend & UX Strategy (Phase 2)
+- **Zero-Downtime Migration**: Maintained the live portfolio page at `portfolio.techarvest.co.zw` throughout the entire transition.
+- **Parallel Loading implemented**: Updated the React `MapComponent` to support a dual-layer strategy:
+    1. **Instant Context**: Immediate rendering of Dynamic World baselines from MinIO via TiTiler.
+    2. **Async Overlay**: Background polling for high-resolution ML predictions.
+- **GitOps Integration**: Moved all Kubernetes manifests to `k8s/base/` and configured ArgoCD to track the Gitea repository.
+
+## 4. Backend Automation & Training (Phase 3)
+- **CI/CD Pipeline**: 
+    - Deployed a Gitea Action runner with **Docker-in-Docker (DinD)** support.
+    - Created a workflow to automatically build and push Worker/API images to Docker Hub on every commit.
+- **Argo Workflows**: Installed to support future automated retraining pipelines.
+- **Training Workflow**: 
+    - Created a reusable `MinIOStorageClient` for high-performance, in-memory dataset loading.
+    - Implemented a training template (`train_v2.py`) that logs to MLflow, saves models to MinIO, and dynamically generates tailored inference scripts.
+
+## 5. Troubleshooting & Stability
+- **Network Resolution**: Diagnosed and bypassed a persistent egress blockage on node `vmi3047336` by migrating the JupyterLab workspace to node `vmi3045103`.
+- **Database Connectivity**: Fixed MLflow connectivity issues by implementing the official image with the correct `psycopg2` drivers.
+- **Cluster Balance**: Carefully managed pod placement to ensure the control-plane node remains safe for other host services like CloudPanel and the mail server.
+
+## 5. Portfolio & Recruiter Experience (Phase 5)
+- **Technical Deep-Dive**: Implemented a comprehensive `TechnicalDocs` suite within the frontend.
+- **Interactive Architecture**: Visualized the system with a custom SVG architecture diagram.
+- **Transparent Engineering**: Documented trade-offs (e.g., Gitea vs GitLab), resource strategies, and MLOps workflows.
+- **Live Observability**: Integrated a service health dashboard and links to monitoring endpoints (Grafana, Uptime Kuma).
+
