Every invocation of this workflow reaches the Run tests step before publishing, but PublishWorkflow_ExposesRegistryCredentialOnlyInIsolatedPublishJob still requires the NuGet publish job to contain permissions: {} and a secrets.NUGET_API_KEY reference (ReleaseWorkflowSecurityTests.cs:36-39). This OIDC change removes both strings, so that test deterministically fails and prevents the publish job from ever reaching nuget/login; update the test to assert the new isolated id-token: write permission and login output instead.
Useful? React with 👍 / 👎.

Update the workflow security test.
PublishWorkflow_ExposesRegistryCredentialOnlyInIsolatedPublishJob requires permissions: {} and secrets.NUGET_API_KEY. Both assertions fail with this trusted-publishing workflow. Update the test to assert the OIDC permission and the absence of the long-lived secret reference.

Pin nuget/login to an immutable commit SHA.
@v1 is mutable. If an attacker retargets this tag, a later publish run executes replacement code with id-token: write. That code can exchange the job OIDC token for a temporary NuGet API key and publish a malicious package. Pin the reviewed release to a verified full commit SHA, with the version in a trailing comment. GitHub identifies a full SHA as the immutable action reference. (docs.github.com)
Based on learnings: third-party actions must use full immutable commit SHAs.
