+
+fix(plugin-sharing, plugin-webhooks): the `by_object` lists of sharing rules and webhooks no longer head each group with an object API name
+
+Clause-②: no
+
+- **`sys_sharing_rule.by_object` and `sys_webhook.by_object` sort by object instead of grouping on it.** Both grouped on `object_name`, and a group header draws its value as stored text, so each group was headed by an API name such as `crm_account`. The sort on `object_name`, then `label`, still keeps one object's rows together, and the Object column still draws each object's icon and label.
+- **Unchanged:** `object_name` stays a declared field on both objects, with the same widget, and no stored column, index or query changes.
+
+A patch: one list view key is removed on each of two shipped platform objects. No export, type, accepted value, stored column or authorable key changes.

+ * with the grouping value as text: its group formatter turns a select value
+ * into its option label and a boolean into Yes / No, and draws anything else
+ * as stored. An `object-ref` field's CELL draws the object's icon and label,
+ * but its group header drew the API name (`crm_account`), so `by_object` read
+ * one machine name per group. #24611 removed the same grouping from
+ * `sys_record_share.by_object`, where the field is a pointer pair's type half.
+ *
+ * A field stores an object's API name when it declares the `object-ref`
+ * widget (the object picker) or when it is the `referenceVia` sibling of a
+ * pointer pair. Enumerated over every object this package ships
+ * (`objects/index.ts`), so a view added later is judged without anyone
