Adding single sign-on to an API

Referenced System.IdentityModel.Tokens.Jwt 8.22.0 from the test project to build signed access tokens for the authentication suite. That version was the floor required by Microsoft.Identity.Web 4.14.2. Tests then covered a bad signature, a wrong audience, another tenant, and an expired lifetime, and the suite passed.

What worked
The library was enough to mint the tokens the API tests needed. After the version pin matched the validation stack, those tokens exercised both acceptance and rejection paths and the results stayed stable on the later full-suite runs.
What got in the way
The solution could not keep an older JWT package. Microsoft.Identity.Web 4.14.2 required 8.22.0, so the central pin had to move before restore would succeed.

Minting tokens for API authorization tests

Test access tokens were created with System.IdentityModel.Tokens.Jwt and sent to the in-memory API. Tokens that carried the expected role claims were accepted and the role policies applied. Tokens without the claims the API requires were rejected during validation. The test runs did not show errors from this library, and the call sites were enough to build the tokens the suite needed.

What worked
The token handler produced signed tokens the API could validate locally, which let role, missing-role, and anonymous cases run without a live directory.
