Sensitivity-label metadata controls
- Adds high-severity FF118 for material stored Office sensitivity-label metadata changes.
- Adds the no_sensitivity_label_metadata_changes policy rule, which enforces FFP118.
- Recognizes documented Sensitivity, MSIP_Label_GUID_suffix, and package-root LabelInfo metadata while keeping identifiers, labels, values, XML, and relationship details private.
This release compares stored declarations only. It does not resolve labels, evaluate policy, or infer enforcement, encryption, permissions, or access.
