## Overview

Org Knowledge Hub is a demo enterprise knowledge-sharing application: employees search and read technical solutions, submit knowledge, and connect with experts; administrators govern solutions, users, taxonomy, and policy. The sampled code supports the search-to-ranking flow, client state providers, connection handling, and Gemini-backed API operations. Upload, analytics, and several administration screens are clear product areas from the tree, but their internal wiring was not sampled, so their connections are kept at the app-entry level where supported.

Main entry points: [`src/App.tsx`](https://github.com/harshavardhan1234-cmd/centralized-hub-/blob/main/src/App.tsx) (App Routing), [`src/pages/SearchPage.tsx`](https://github.com/harshavardhan1234-cmd/centralized-hub-/blob/main/src/pages/SearchPage.tsx) (Solution Search), [`src/context/KnowledgeContext.tsx`](https://github.com/harshavardhan1234-cmd/centralized-hub-/blob/main/src/context/KnowledgeContext.tsx) (Knowledge State), [`src/context/ConnectionContext.tsx`](https://github.com/harshavardhan1234-cmd/centralized-hub-/blob/main/src/context/ConnectionContext.tsx) (Connection State)
