- Line 1154: Update the public status and cancel methods to include explicit
return annotations: status should return JobStatus, and cancel should return
None. Keep their existing behavior unchanged.
- Around line 1154-1155: Document the complete lifecycle contract for
status(job_id) and cancel(job_id) in
python/cuopt/cuopt/grpc/client/grpc_client.pyx at lines 1154-1155 and 1178-1179,
including the job_id parameter, JobStatus return value for status, None return
value for cancel, and RoutingSolveError behavior on RPC failures. Update
docs/cuopt/source/cuopt-grpc/routing.rst at lines 62-64 with the same details
and add an API reference entry for JobStatus, including its terminal values.
In `@python/cuopt/cuopt/tests/routing/test_routing_grpc_client.py`:
- Around line 83-88: Update the cancellation test around _small_vrp() so it
deterministically keeps the job in QUEUED or PROCESSING, or stubs the lifecycle
RPCs, before invoking cancellation. Ensure the test always exercises
client.cancel() and verifies the resulting CANCELLED status instead of skipping
when the job completes early.

Think code rabbit changes would be the ones needs to be addressed, rest seems to be good shape.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Remove submit() from the non-completion error contract.
Line 61 documents that submit() returns a job_id. Lines 65-68 document that wait() observes terminal completion. Therefore, submit() cannot raise RoutingSolveError because the job does not complete. Limit this statement to solve() and document submit-time RPC or serialization errors separately if needed.
Proposed fix
-``submit`` and ``solve`` raise ``RoutingSolveError`` when the job does not
-complete. ``status`` and ``cancel`` raise ``RoutingSolveError`` on RPC
-failure; ``cancel`` also raises for an unknown ``job_id``.
+``solve`` raises ``RoutingSolveError`` when the job does not complete.
+``submit`` returns a ``job_id`` before the job reaches a terminal status.
+``status`` and ``cancel`` raise ``RoutingSolveError`` on RPC failure;
+``cancel`` also raises for an unknown ``job_id``.As per path instructions, documentation changes must accurately describe public API behavior.
