+# DigitalTwin - Optimum Overhaul App (be-optimumoh) API Documentation
+
+This document maps all the API endpoints, route handlers, database models, and external service layers inside the `be-optimumoh` microservice. It is a FastAPI-based backend engine managing Overhaul schedules, standard scopes, spare parts readiness, Temporal workflow executions, and optimization/constraint calculations.

+
+## 🛡️ App Middlewares & Framework Architecture
+
+### 1. Security Headers Middleware
+FastAPI adds rigid HTTP security headers to all incoming connections inside `src/main.py`. In production, it enforces `Strict-Transport-Security`, `X-Frame-Options` (DENY), and full CSP blockades. In development mode, it supports relaxed parameters.
+
+### 2. Request Sanitization & Slowapi Limiting
+All JSON and path structures pass through `RequestValidationMiddleware` (`slowapi` integration) to enforce rate limiting thresholds globally, returning standard payload error formatting on breaches.
+
+### 3. Multi-Session Context Scoping
+Scoped database sessions are generated per request context dynamically utilizing ContextVars in `src/context.py` and SQLAlchemy's async connection pool engine:
+* `db` session: Optimum overhaul local PostgreSQL dataset (`default`).
+* `collector_db` session: Asset metadata and equipment configurations.
