  12. Pipeline Secrets advanced

    A team stores no credentials in its repository. The cloud role is assumed through OIDC federation, the registry token lives in a managed secret store, and the build never prints it. Over one weekend an attacker publishes a malicious version of the team's package, and the audit trail shows the push came from the team's own pipeline. Trace how, and name the structural fix.
