A team configures a protected environment named agent-execution. A workflow job that starts a Copilot agent task references that environment. The environment has required reviewers, and the workflow is triggered manually after an issue plan has been posted. Evaluate the following statements. 1. The job can wait for environment approval before running protected steps 2. The workflow_dispatch trigger alone proves the agent plan was approved 3. Required reviewers can help enforce a human gate before execution

Statement 1 is correct because GitHub Actions environments with required reviewers will pause job execution until the specified reviewers approve the deployment. This allows for a human gate before protected steps run. Statement 2 is incorrect. While workflowdispatch allows manual triggering, it doesn't inherently prove an agent plan was approved. The approval mechanism is separate and typically involves a review process, not just the trigger type. Statement 3 is correct. Required reviewers are a core feature of GitHub Actions environments, specifically designed to enforce a human gate, ensuring that changes or deployments are reviewed and approved before proceeding, especially for sensitive operations like agent execution.
