+fix(security,approvals,metadata-core): restore batch routes on the eight objects the #3391 P1 companion fix missed (#3026)
+
+The #3391 P1 contract made the bulk gate `bulk ∧ derived(child)`: a batch
+request is admitted only when the object grants the `bulk` **primitive** and the
+batched child operation is itself allowed. Before that, the `*Many` routes
+checked only the child verb, so a boilerplate CRUD-five whitelist
+(`['get','list','create','update','delete']`) batched fine.
+
+The companion fix — adding the `bulk` primitive wherever an explicit whitelist
+survived — was applied only inside `platform-objects`. Eight objects carrying
+the same boilerplate live in other packages and kept the gap, so `/batch`,
+`createMany`, `updateMany` and `deleteMany` answered `405
+OBJECT_API_METHOD_NOT_ALLOWED` on objects whose single-record create/update/
+delete were wide open. `data-objectstack` rethrows that 405 without falling back
+to per-row writes, which surfaced as a hard error on multi-select delete in the
+Setup grids.
+
+Objects reclaimed (whitelist now `['get','list','create','update','delete','bulk']`):
+`sys_capability`, `sys_permission_set`, `sys_position`,
+`sys_position_permission_set`, `sys_user_permission_set`, `sys_user_position`
+(plugin-security); `sys_approval_delegation` (plugin-approvals);
+`sys_view_definition` (metadata-core).
+
+No new authority is granted: `bulk` only permits batching verbs each object
+already exposes one record at a time, and every batched row still passes the
+same row- and field-level permission checks. The whitelists stay explicit rather
+than being deleted — seven of the eight are `managedBy`, and
+`reconcileManagedApiMethods` (ADR-0103 D3) early-returns on a non-array
+`apiMethods`, so dropping the line would silently disable the managed-write
+backstop.
