+fix(runtime): creating, updating or cloning a flow over `/automation` now records which user saved it
+
+Clause-②: no
+Metadata-protocol: none
+
+`POST /api/v1/automation`, `PUT /api/v1/automation/:name` and `POST /api/v1/automation/:name/clone` store the flow as a `sys_metadata` row. Until now that row named nobody: `created_by` and `updated_by`, and `recorded_by` on its `sys_metadata_history` entry, were null even when a signed-in administrator made the request. The `/meta` door already recorded the user. All three `/automation` doors now pass the signed-in user's id as the save's actor, so the row names that user, the same way `PUT /api/v1/meta/flow/:name` does. A request with no user, such as the engine's own system call, still saves with no actor, as before.
+
+The `sys_audit_log` row for the same write is not changed by this fix. It still has a null `user_id` on every metadata door, `/meta` included.

+/**
+ * [#27414, ADR-0073 D3] The `/automation` definition doors record who saved.
+ *
+ * `POST /`, `PUT /:name` and `POST /:name/clone` persist through one path,
+ * `registerAndSaveFlow`, which called `protocol.saveMetaItem` with no `actor`
+ * although the execution context it had just admitted carried the caller's
+ * `userId`. So the `sys_metadata` row a signed-in admin created, updated or
+ * cloned recorded `null` in `created_by` / `updated_by` and in
+ * `sys_metadata_history.recorded_by`. The save now passes the caller's id the
+ * way the toggle door does (`activationCaller`), and nothing when the context
+ * has no user.
+ *
+ * ## The rig
+ *
+ * One REAL store, as in `meta-save-actor.test.ts`: better-sqlite3 `:memory:`,
+ * the real `sys_metadata*` objects and a real
+ * `ObjectStackProtocolImplementation`, so the claim is about the rows, read
+ * back after every save. The automation service is a fake that holds the
+ * flows it is given; the door is driven through the real `HttpDispatcher`.
+ *
+ * The CONTROL is a caller with no user (`isSystem`, the engine's own
+ * self-invocation shape): its save records null, as before.
