+This operation follows the [FHIR Asynchronous Bulk Data Request Pattern](https://www.hl7.org/fhir/async-bulk.html); the completion response is specified once in [Common Operation Behavior — Asynchronous Delivery](operations-common.html#asynchronous-delivery):
 
 1. Client sends request with `Prefer: respond-async` header and query source parameters
 2. Server returns `202 Accepted` with `Content-Location` header pointing to status URL
 3. Client polls the status URL for export progress
 4. Server responds with `202 Accepted` while export is in progress (MAY include interim results)
-5. Upon completion, server returns `303 See Other` with `Location` header pointing to result URL

+**Note**: This operation uses a FHIR `Parameters` resource as the manifest instead of the Bulk Data JSON manifest object to:
 
 - Provide structured status reporting and metadata
 - Allow extensible output metadata specific to export operations
 - Maintain consistency with other FHIR operations
 
-**Note**: The `303 See Other` redirect pattern cleanly separates status polling from result retrieval, eliminating ambiguity around error handling and request header scope.
+**Note**: Completion is signalled by `200 OK` with the manifest in the body of the status-poll response, as in the FHIR Asynchronous Bulk Data Request Pattern. The operation does not use a `303 See Other` redirect to a separate result resource, so standard Bulk Data clients interoperate without special handling.

 ##### Header Scope
 
-Request headers sent during status polling apply **only to the status response**, not to the final operation result. This separation:
-
-- Allows different content negotiation for status vs. result responses
-- Enables servers to use different formats for interim status (e.g., minimal JSON) vs. final results (e.g., detailed Parameters)
-- Eliminates ambiguity about which response the headers apply to
+Each status-poll request's headers apply to **that poll's response**. Because
+completion is delivered as `200 OK` with the manifest in the body of the
+status-poll response (there is no separate result resource), the `Accept` header
+sent on the completing poll governs the representation of the manifest. This
