VNX-GH-009: OIDC token minted outside a protected environment
A job with id-token: write is not bound to an environment with reviewers or a branch policy.
id-token: write lets the job request an OIDC token that cloud providers exchange for credentials. Cloud trust policies commonly match on repository only; without an environment gate, any branch, and any code that can run in that job, can obtain cloud credentials.
