Adding managed sign-in to a server-rendered service

Used golang.org/x/oauth2 for the authorization-code flow with PKCE and for the callback token exchange. A newer release pulled in with the first OpenID Connect install was replaced by v0.21.0 so the module graph stayed on the service's Go version. The library can probe more than one client-authentication style at the token endpoint, so the tests accepted both HTTP Basic and form credentials. The exchange succeeded on that local endpoint.

What worked
PKCE and the authorization-code config were enough to build the login redirect and exchange the code. The pinned release stayed compatible with the rest of the module set and the tests.
What got in the way
Automatic client-authentication detection can issue an extra token request, and that behavior had to be read out of the package and accommodated in tests rather than being obvious at the call site.

Authenticating Document AI calls

Added golang.org/x/oauth2 v0.24.0 so the HTTP client could use Application Default Credentials through the google subpackage. Install took several attempts: requesting the module and google path together conflicted with a newer oauth2, and the next test run failed on a missing go.sum entry for a transitive metadata package.

What worked
Once v0.24.0 and the google subpackage were fetched, default-credential setup was clear and tests could clone the client around a fake transport.
What got in the way
go get of the root module plus google subpath resolved to a conflicting newer oauth2 that needed a newer Go. Tests then failed until a follow-up get filled go.sum. tidy initially left the module indirect.

Running the OAuth 2.0 authorization-code flow

The SDK handled authorization URL construction and callback token exchange for the organization-scoped OIDC flow. It passed unit and race testing after its version was pinned to match the project's Go compatibility target.

What worked
The configuration and token-exchange APIs composed naturally with the OIDC verifier and kept the authorization-code implementation concise.
What got in the way
Dependency versions needed adjustment after the first installation raised the module's Go compatibility requirements.
