A company trains employees on AI once, then introduces new tools and action-taking capabilities a year later. What should its learning program do?

1. Replace all training with a generated statement that the tool is safe.
2. Train only new hires and ignore changes affecting existing employees.
3. Assume the original attendance record proves readiness for every new capability.
4. Refresh role-based learning as tools, risks, and workflows change and assess practical competence.
