+feat(verify): `hooks.run` takes the system principal on an insert and a delete, so a user-less record trigger can be driven
+
+Clause-②: yes (widening)
+
+An app's tests can drive a record-change flow fired by a write with no user (an integration's or a system job's insert or delete) through the in-process handle, so a suite no longer hands a flow a record through the booted kernel's `automation` service by hand.
+
+- **`hooks.run(object, 'insert' | 'delete', input, { system: true })`** is the engine's own `insert` / `delete` under `{ isSystem: true }`, the same call the person's write makes with only the context changed. `{ system: true }` on `update` is unchanged. No permission gate applies. The bound hooks still run (they see `session.isSystem` and no `userId`), declared validations still refuse, and the record-change trigger fires the object's flows with no trigger user.
+- **A record the engine no longer holds.** A system (or a person's) delete hands a `record-after-delete` flow the row's pre-image as `record` and as `previous`, and by then the engine no longer holds the row: the flow's `get_record` of that id finds nothing. A `record-before-delete` flow on the same delete still finds it.
+- **Not `seed`.** `seed(object, rows)` also runs as the system, and it sets `skipTriggers`, so it fires no record-change flow: use it for end-state fixture data, and `{ system: true }` for a write the app should react to.
+- A call naming both callers (`{ as: token, system: true }`) is still refused with `code: 'INVALID_REQUEST'`, `status: 400`, before anything is written. Every other refusal is the engine's own error, unchanged: assert on its `code` and `status`.

 An app's tests reach two more engine write paths through the in-process handle, so a suite no longer calls the booted kernel's `objectql` service by hand for them.
 
 - **The system principal on an update.** `hooks.run(object, 'update', { id, ...fields }, { system: true })` writes one row by id under `{ isSystem: true }`, the context a system job or an integration writes under. No permission gate applies. The bound hooks still run (they see `session.isSystem` and no `userId`), declared validations still refuse, and the record-change trigger fires its flows with no trigger user. The new type is `AsSystem` (`{ system: true }`), exported beside `AsUser`.
-  - Only `update` takes it. `{ system: true }` on `insert` or `delete`, or beside an `as` token, is refused with `code: 'INVALID_REQUEST'`, `status: 400` before anything is written. Fixture rows are still `seed(object, rows)`, which also skips record triggers.
+  - `{ system: true }` beside an `as` token is refused with `code: 'INVALID_REQUEST'`, `status: 400` before anything is written. Fixture rows are still `seed(object, rows)`, which also skips record triggers. (`insert` and `delete` take `{ system: true }` too: see the system insert and delete entry.)
 - **The predicate update.** `hooks.updateWhere(object, where, data, opts)` is the engine's own predicate path, `update(object, data, { where, multi: true, context })`. It writes one payload to every row `where` selects and resolves with the affected-row count. The engine dispatches `beforeUpdate` and `afterUpdate` once per matched row, each bound to that row's own pre-image as `previous`, so record-change flows evaluate and fire per row. No REST door reaches this path: `POST /data/:object/updateMany` writes by id. The caller is `{ as: token }` or `{ system: true }`.
   - It refuses with `code: 'INVALID_REQUEST'`, `status: 400`, before the engine is touched, a `where` that is not an object, and a call the engine's own update dispatch would write by id: a `where` that names only an `id`, or an `id` in `data` beside a `where` that selects by nothing else. Write one row by id through `hooks.run(object, 'update', { id, ...fields }, opts)`. An `id` inside a larger predicate (`{ id, status: 'open' }`) stays a predicate update. An `id` in `data` beside a real predicate is refused by the engine itself, as it is on every caller.
