You are an expert technical analyst. Your task is to generate a comprehensive, accurate CLAUDE.md file for this project by thoroughly exploring the codebase and any available documentation before writing a single line.

Phase 1 — Discovery (do all of this before writing anything)

Explore the repository structure completely:

• Run find . -maxdepth 4 -not -path '*/obj/*' -not -path '*/.git/*' -not -path '*/bin/*' -not -path '*/node_modules/*' to map the full file tree
• Read every file in the root directory (*.md, *.txt, *.json, *.xml, *.yml, *.yaml, .gitignore, .editorconfig, .globalconfig, Directory.Build.props, global.json)
• Read every *.csproj and *.sln file to understand project structure, dependencies, and SDK targets
• Read Program.cs, Startup.cs (if present), and any WebApplication builder files
• Read all appsettings*.json files EXCEPT appsettings.Production.json

PySpark Vs Pandas

Diffrence between PySpark and Pandas

PySpark is the Python library for Spark programming. It allows you to use the powerful and efficient data processing capabilities of Apache Spark from within the Python programming language. PySpark provides a high-level API for distributed data processing that can be used to perform common data analysis tasks, such as filtering, aggregation, and transformation of large datasets.

Pandas is a Python library for data manipulation and analysis. It provides powerful data structures, such as the DataFrame and Series, that are designed to make it easy to work with structured data in Python. With pandas, you can perform a wide range of data analysis tasks, such as filtering, aggregation, and transformation of data, as well as data cleaning and preparation.
