# Read a page's column locks

Every LOCKED column on one record page, with the audiences each lock names — who may see the column and who may write it. Columns with no policy are simply absent. Workspace admin, because an audience says who in the workspace may see what; a member asking what applies to THEM reads `get_definitions_key_column-policies_effective` instead.

Access class: `def:admin`.
