| 26 |
* - {@see bucket_drift} — the per-id mismatches inside ONE bucket (the drill-down). |
| 27 |
* - {@see bucket_listing} — the authoritative live {id, digest, object_type} for one bucket. |
| 28 |
* |
| 29 |
* Plus the two scoping questions the same id-space owns: |
| 30 |
* {@see published_product_ids} (the readable-catalog filter, one home for a rule |
| 31 |
* that used to be re-spelled in every consumer) and {@see needs_product_rebuild}. |
| 32 |
* |
| 33 |

| 34 |
