- query_string required for and/or filters to apply; use "%" as wildcard
- Total count is in meta.data_list_count, not top-level
- id_random is None in responses; Vision ID convention uses {obj_type}_id
- tags comes back as string on read, not list — normalize before joining
- Replace stale "Planned: Search Improvements" with current signature + notes
- Clarify date_to boundary (lte midnight, use next day to include full day)
