saved_query_column_annotations

Read and edit semantic descriptions of data-modelling views and columns surfaced to the AI agent.

List can be filtered to one view with ?saved_query_id=<uuid>. Any create or update is treated as a user edit (is_user_edited=True), which protects the row from being overwritten by automatic enrichment. Create upserts on (saved_query, column_name); the view cannot be changed after creation.
