- Distinct from `SAIF.Web.HttpContextExtensions`: supplies the request-diagnostic dictionary and URL/application-name parsing helpers that `HandleExceptionAttribute` and `SaifAuthorizeAttribute` use to build log entries and route keys.

## Context
- Namespace: `SAIF.Web.Mvc`
- Assembly/package: `SAIF.Framework.Web.Mvc (source-shipping NuGet package)`
- Kind: static class
