Reverse-Engineer .NET 10 Blazor Application into AI Unified Process Artifacts

Background

An engineering team maintains a C# / Blazor .NET 10 e-commerce platform (inputs/ArtisanShop.Web). The application uses Entity Framework Core for data access (DbContext), Blazor interactive components (.razor) for UI, ASP.NET Core Identity for authentication, and EF Core migrations under Migrations/.

The engineering lead wants to produce a full set of AI Unified Process artifacts from the existing .NET codebase so new developers can understand system capabilities without reading through C# source files.

The codebase is in the inputs/ directory. It contains an ArtisanShop.sln, ArtisanShop.csproj, Program.cs, Blazor page components under Components/Pages/, EF Core DbContext entity configurations, and EF Core migration snapshots under Migrations/.

Your Task

Each artifact must conform exactly to the standard AI Unified Process document format — diagram layout, spec structure, and entity model attribute tables using the closed AI Unified Process data-type vocabulary (Long, Integer, String, Decimal, Boolean, Date, DateTime).

Reverse-engineer the .NET 10 codebase into the three AI Unified Process artifacts:

1. docs/use_cases.puml — PlantUML use case diagram listing all actors and use cases
2. docs/use_cases/ — one specification file per use case (e.g. UC-001-place-order.md)
3. docs/entity_model.md — entity model with Mermaid ER diagram and attribute tables

Document your approach in docs/PLAN.md before writing specs, recording:

• The full list of Blazor components (.razor), Minimal APIs, or Controllers found during initial scan
• How you grouped those entry points into feature clusters
• Any infrastructure tables excluded from the entity model

Output Specification

All output files go under docs/:

• docs/PLAN.md — clustering plan
• docs/use_cases.puml — PlantUML diagram
• docs/use_cases/UC-XXX-short-name.md — one file per use case (kebab-case filenames)
• docs/entity_model.md — entity model

Do not modify any file under inputs/.
