Now I have the full picture. The entity already has FromAt/ToAt fields — just need to expose them in the API and UI. For SubArea, it lives in tag_metadata so I'll add a [NotMapped] property and batch-join it. Let me make all the changes.
# Todos
[•] Add [NotMapped] SubArea to PidEquipment entity
[ ] Add FromAt/ToAt to Create/Update DTOs
[ ] Update PidExtractorService: GetEquipmentAsync batch sub_area, Update/Create handle FromAt/ToAt
[ ] Update PidController response: add fromAt, toAt, subArea
[ ] Update pid.html table headers: new column order + sub_area, from_at, to_at
[ ] Update pid.js table row rendering for new columns
[ ] Update pid.js add-row and save-row for FromAt/ToAt
[ ] Build and verify
