- Around line 1126-1128: Update the cancellation check in _respond_with_kv so
IDs present in _pre_cancelled_rids are treated as cancelled alongside
_cancelled_rids, preventing _save_peer_req_info from retaining late requests.
Add a regression test covering CANCEL_SESSION before TxSession setup and
REQUEST_DATA, verifying the receiver does not remain blocked.
In `@tensorrt_llm/_torch/pyexecutor/py_executor.py`:
- Around line 6703-6705: Update the remote abort dispatch flow around the
exception handler so it returns whether dispatch succeeded and keeps failed
abort requests pending for retry, even when py_kv_transfer_timed_out is set.
Ensure timeout scanning can reach the retry path until the transfer succeeds or
becomes terminal, and catch only the specific expected transport exception while
allowing programming errors to propagate.

The harnesses give the context and generation requests different ids, so this preference changes the key the generation side registers under and the sender stops matching. Could they be updated in this PR?

The timeout check runs before the response handler in the same iteration, and that handler already cancels the session and sends its own cancel. Is this second call still needed?
There was a problem hiding this comment.
Also, the pipeline-parallel loop reaches this timeout check only when context transfers are in flight, so a generation-only server never does. Not from this PR, but it bounds the fix.

This value is also the on/off switch for the bounce path, so it moves these tests onto a different route. Could it land separately from the cancellation fix?

The same order is already open-coded near native/transfer.py. Could that site use this helper too? disaggregated_params.py still resolves in the opposite order.

Add regression coverage for preallocated-slot reuse.
Eagle3ResourceManager.prepare_resources and MTPHiddenStatesManager.prepare_resources must reuse the slot registered by add_dummy_requests and allocate a new slot for a different request ID. Existing tests cover pool sizing and direct slot_manager.add_slot calls, but not the add_dummy_requests to prepare_resources sequence. A regression that removes either reuse guard can call add_slot for an already mapped non-CUDA-graph dummy and fail duplicate-registration handling. Add focused cases for both managers in tests/unittest/_torch/speculative/test_spec_slot_pool_sizing.py. Assert that the preallocated request keeps its slot and that a new request ID receives a different slot.

Add coverage for differing retry IDs. The existing unit test checks receiver metadata only. It does not cover session registration, task dispatch, and transfer completion with differing IDs. Add a regression test in tests/unittest/disaggregated/test_kv_transfer.py that uses the context transfer ID and a different generation disagg_request_id. Assert that the transfer completes and the wire request uses the context ID.

459, Add a regression test in the disaggregated KV transfer tests that supplies
a context transfer ID different from the generated disaggregation request ID,
then exercises session registration, task dispatch, and transfer completion.
Assert the transfer succeeds and the wire request uses the context transfer ID,
covering the resolve_transfer_rid behavior in _unique_rid.
