* Adapts a WordPress TERM (category / brand — taxonomy product_cat / product_brand) |
| 14 |
* to the small WC_Data meta contract that Pos_Uuid::ensure_uuid and |
| 15 |
* prune_duplicate_uuid_meta duck-type on (get_meta_data / update_meta_data / |
| 16 |
* save_meta_data / delete_meta_data_by_mid). WP_Term is NOT a WC_Data object and |
| 17 |
* get_term_meta returns bare scalar values with no meta-id, so the uuid stamping |
| 18 |
* logic cannot be reused on a term directly — this thin adapter over wp_termmeta |
| 19 |
* lets the audited ensure_uuid/dedup path stamp terms unchanged, exactly as |
| 20 |
* WC_Customer (which IS WC_Data) let it stamp customers. |
| 21 |
* |
| 22 |
* get_meta_data surfaces the per-row meta_id (queried from wp_termmeta), which |
| 23 |
* prune_duplicate_uuid_meta needs to delete duplicate uuid metas by mid. |
| 24 |
* update_meta_data has WC_Data's replace-or-add semantics (a single key holds one |
| 25 |
* value), applied on save via update_term_meta — so re-keying a collided term |
| 26 |
* REPLACES its uuid rather than leaving a second one behind. |
