As backend services mature, handlers start repeating the same request plumbing over and over again. Tenant resolution, actor identification, correlation values, access-scoped metadata. None of this is business logic, but all of it is required before any business logic can run.

In a typical multi-tenant API, every handler opens with five or six lines of header extraction and default-value logic. When that logic is duplicated across fifty endpoints, small inconsistencies creep in. One handler reads X-Tenant-ID, another reads X-TenantID, a third falls back to a query parameter. Custom context gives that plumbing a single, typed home.
