Status retrieval and cancellation are conservative in the active Fabric adapter. Treat them as capability-gated surfaces: call capability discovery before depending on them.
Fabric Position
| Operation | Current guidance |
|---|---|
| Status lookup | Use only when the service advertises support |
| Response retrieval | Use only when persistence support is explicitly enabled |
| Cancellation | Use only when the generation runtime advertises cancellation |
Legacy REST
Older clients may reference:
GET /api/v1/status/{request_id}GET /api/v1/retrieve/{request_id}
Those routes belong to the optional ensemble-rest compatibility process and should not be assumed available on the active /rpc service.
