new .NET 10 Blazor solution (NEW/), OpenSpec specifications,
documentation, and project configuration.

Setup Solution Foundation

Summary

Set up the .NET 10 solution infrastructure including dependency injection configuration, options pattern for configuration binding, and modular service registration extension methods. This establishes the architectural foundation for all subsequent migration phases.

Scope

In Scope

Program.cs with DI container configuration
appsettings.json structure with sections for each module
Service registration extension methods (AddDataAccess, AddDataSync, AddAuth, AddExcelExport)
Options classes for IOptions configuration binding
Project references and NuGet package dependencies

Out of Scope

Actual service implementations (deferred to domain-specific phases)
Database connection testing (covered by migrate-database-schema)
Authentication implementation details (deferred to auth phase)
Background service scheduling (deferred to data-sync phase)

Motivation

A well-structured DI configuration provides:

Modular, testable architecture with clear separation of concerns
Strongly-typed configuration binding via IOptions pattern
Extension methods that encapsulate module-specific registration logic
Clear dependency graph visible in Program.cs

Acceptance Criteria

Solution builds successfully with dotnet build
All Options classes bind correctly from appsettings.json
Extension methods register services with appropriate lifetimes:
- Scoped: Database services, repositories
- Singleton: Configuration, HTTP clients
- Transient: Short-lived processors
Program.cs clearly shows module registration order
openspec validate setup-solution-foundation --strict passes

Dependencies

migrate-database-schema (provides JdeScoping.Database project)

Risks

Risk	Mitigation
Circular dependencies	Extension methods register only their module's services
Configuration drift	Options classes map 1:1 with appsettings sections
Missing services at runtime	Startup validation via GetRequiredService checks
