+# Architecture and Contributor Guide
+
+Overview
+- This repository hosts a production-ready MVP for SolarPulse Viz Real, an open-source framework for real-time visualization and anomaly insights across distributed solar, wind, and storage assets.
+
+Tech Stack
+- Backend: Python 3.9+ with FastAPI for REST APIs
+- ML: Scikit-learn (IsolationForest) for unsupervised anomaly detection
+- Data: SQLite (via SQLAlchemy) for lightweight persistence in the MVP
+- Adapters: Lightweight Python modules for telemetry gateway and inverter fault detector
+- Packaging: PyProject.toml with setuptools-based build
+
+Key Modules
+- src/idea46_solarpulse_viz_real/main.py: FastAPI app with endpoints for health and telemetry intake
+- src/idea46_solarpulse_viz_real/anomaly.py: IsolationForest-based detector (embedded in app for MVP)
+- adapters/telemetry_gateway.py: Starter adapter to parse telemetry payloads
+- adapters/inverter_fault_detector.py: Starter adapter for fault detection logic
+- tests/: Basic test suite to verify API and anomaly scoring
+
+Testing & Running
+- test.sh: Script to run tests and build (see file for details)
+- Tests use pytest; you can extend tests to cover more endpoints and adapters
+
+Publishing
+- When you’re ready to publish, ensure READY_TO_PUBLISH exists at repo root and that tests pass locally.
+
+Notes
+- This MVP emphasizes minimal, correct changes with clean interfaces. Iterate with the swarm by adding more adapters, data contracts, and dashboards in subsequent sprint turns.

-Source logic for Idea #46
\ No newline at end of file
+SolarPulse Viz is a production-focused framework for real-time visualization and actionable anomaly insights across distributed solar, wind, and storage assets.
+
+- Mobile-first dashboards with real-time and historical time-series views across multiple sites
+- Standardized data contracts and a lightweight interoperability bridge
+- Lightweight ML-based anomaly detector (unsupervised models)
+- AR maintenance overlays and cross-domain storytelling templates
+- Offline-friendly data caching with delta-sync when connectivity returns
+
+This repository implements a solid, production-grade chunk of that vision as a Python FastAPI service, suitable for extension by agents in sprint-based workflows.
+
+How to run locally
+- Install dependencies: python -m pip install -e .
+- Run: uvicorn idea46_solarpulse_viz_real.main:app --reload --port 8000
+
+This is a scaffold and MVP focused on the core server and anomaly-detection workflow. See AGENTS.md for architecture and contribution details.
