## Overview

This is a Scrum/DevOps project-management domain prototype. Its main user-facing lifecycle is backlog work moving through task and test states within a sprint, with a separate pipeline model for source, package, build, test, analysis, and deployment actions. Other documented branches cover discussion, team and project domain concepts, reporting, and notifications. The tree and README support these capabilities, but sampled source is limited; links are shown only where documented or directly evidenced, not as a presumed end-to-end application flow.

Main entry points: [`DevOps/Adapters/IMediaAdapter.cs`](https://github.com/mjunhaochen/devops/blob/main/DevOps/Adapters/IMediaAdapter.cs) (Media adapters), [`DevOps/Domain/Sprint.cs`](https://github.com/mjunhaochen/devops/blob/main/DevOps/Domain/Sprint.cs) (Sprint lifecycle), [`DevOps/Domain/Project.cs`](https://github.com/mjunhaochen/devops/blob/main/DevOps/Domain/Project.cs) (Project), [`DevOps/Domain/BackLogItem.cs`](https://github.com/mjunhaochen/devops/blob/main/DevOps/Domain/BackLogItem.cs) (Backlog items)
