+feat(spec)!: `@objectstack/spec/kernel` no longer exports `MetadataEvent(Schema)` / `MetadataBulkRegisterRequest(Schema)` — the bare names belong to `./api` alone (#4587)
+
+The names `MetadataEvent` / `MetadataEventSchema` /
+`MetadataBulkRegisterRequestSchema` resolved to **two different declarations**
+depending on the import path (`./api` vs `./kernel`) — the #4411 dual-source
+trap. Resolution (three-repo, import-statement-level consumer scan: framework,
+cloud, objectui — the `./kernel` copies had zero importers outside their own
+unit test):
+
+- **Removed** `MetadataEventSchema` / `MetadataEvent` from
+  `@objectstack/spec/kernel`. This was a lifecycle-event envelope
+  (`event: 'metadata.registered' | … | 'metadata.exported'`, plus
+  `actor`/`payload`/`namespace`) that **nothing ever emitted or consumed** —
+  the vocabulary appears in no producer in any of the three repos. The live
+  contract is `./api`'s `MetadataEvent(Schema)`
+  (`type: 'metadata.{type}.{created|updated|deleted}'`, with `id` / `definition`
+  / `userId`): `MetadataManager` publishes those events to the realtime
+  service and `@objectstack/client` / `@objectstack/client-react` subscribe to
+  them.
+  - FROM `import { MetadataEvent } from '@objectstack/spec/kernel'` →
+    TO `import type { MetadataEvent } from '@objectstack/spec/api'`.
+    **Shape change**: the api event has `id` (uuid), `type`
+    (`metadata.{type}.{created|updated|deleted}`), `definition`, `userId`; the
+    removed kernel shape's `event` / `actor` / `payload` / `namespace` fields
+    do not exist there. If you needed runtime *watch* events, that contract is
+    `MetadataWatchEvent` in `@objectstack/spec/system`; repository change-log
+    events are `MetadataEvent` from `@objectstack/metadata-core` (ADR-0008) —
+    a third, unrelated declaration that is not part of `@objectstack/spec`.
+- **Removed** `MetadataBulkRegisterRequestSchema` /
+  `MetadataBulkRegisterRequest` from `@objectstack/spec/kernel`. It was a dead
+  near-duplicate of the REST contract that also diverged from the enforced
+  write path: its per-item `namespace` field exists neither in
+  `IMetadataService.bulkRegister` (contracts) nor in
+  `MetadataManager.bulkRegister`, and `namespace` is deprecated platform-wide.
+  - FROM `import { MetadataBulkRegisterRequestSchema, MetadataBulkRegisterRequest } from '@objectstack/spec/kernel'` →
+    TO `import { MetadataBulkRegisterRequestSchema, type MetadataBulkRegisterRequest } from '@objectstack/spec/api'`
+    (the `POST /api/meta/bulk/register` contract; the type export is new on
+    `./api` in this release). **Shape change**: items are strictly
+    `{ type, name, data }` — a per-item `namespace` no longer parses into the
+    accepted shape. `MetadataBulkRegisterRequest` is the authoring-side type
+    (`z.input`): `continueOnError` / `validate` stay optional and carry
+    defaults, as before.
+- `@objectstack/spec/api`'s `MetadataEvent(Schema)` and
+  `MetadataBulkRegisterRequestSchema` are **unchanged** and are now the sole
+  owners of the bare names. Imports from `./api` need no migration.
+- `@objectstack/spec/kernel`'s `MetadataBulkResultSchema` /
+  `MetadataBulkResult` are **unchanged** — only the bulk *register request*
+  pair moved.
+
+`dual-source-exports.baseline.json` shrinks by exactly these 3 rows (31 → 28,
+#4535 C2).
