/** |
| 9 |
* Label tools — the cross-entity tagging system. |
| 10 |
* |
| 11 |
* apply-labels attaches/detaches existing labels to an order, customer, or |
| 12 |
* subscription. It works on label IDs (from list-reference-data with |
| 13 |
* kind=labels), so it never needs to know how a label's value is stored. |
| 14 |
* |
| 15 |
* Parameter design: explicit add/remove delta arrays rather than a "set the |
| 16 |
* full list" payload — the agent rarely knows the current set, and deltas are |
| 17 |
* what it actually intends ("tag this order VIP"). We return the resulting set |
| 18 |
* so the agent can confirm. |
| 19 |
* |
| 20 |
* Managing label DEFINITIONS (create/rename/delete the labels themselves) is |
| 21 |
* deliberately not exposed yet — the underlying value column is a serialized |
| 22 |
* blob whose shape we don't want an agent guessing at. |
