According to the AgentForce Prompt Template Versioning Guide, when a prompt template version is marked as immutable, it means that no edits or modifications can be made to that version after it has been activated. This ensures that the logic, wording, and grounding parameters tied to that version remain locked and consistent for auditing, reproducibility, and compliance purposes.
If further changes are required, the system automatically creates a new draft version of the template. The old version remains immutable and preserved for traceability.
Option B is incorrect because multiple versions can exist, and older versions can remain active under specific testing or rollback scenarios. Option C is partially true but incomplete—the immutability refers to the frozen nature of an active version, not just version creation.
Thus, the correct explanation is Option A – Once a prompt template version is activated, it becomes immutable and cannot be changed.
