Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This refactor centralizes routing conversion and solver preparation, but some requests without task data and an explicit time limit can fail with a server error rather than a handled response.

35-51: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd negative-path coverage for the migrated validation.
The new tests cover the happy path only.
populate_optimization_datacarries the 400-level validation rules for a missing cost matrix, for bothcost_matrixandwaypoint_graphsupplied together, and for both travel-time representations supplied together. Add cases that assertHTTPExceptionandstatus_code == 400for these inputs. Add a case for the capacity/demand dimension mismatch increate_data_modelif a GPU is available in the test environment.As per path instructions: "Edge cases: empty, infeasible, unbounded, degenerate problems" and tests should "validate actual conversion, solver settings, edge cases, and invalid inputs rather than merely avoiding exceptions".

- Around line 149-151: Update the time-limit initialization in the solver
configuration conversion flow to validate that task_data is present before
accessing task_data.task_locations. When solver_config.time_limit is absent and
task_data is missing, raise the established client-input validation error with
an actionable message so the request returns 400; preserve the existing
std_solver_time_calc behavior when task_data is available.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Guard against a missing task_data when the time limit is absent.
If a request supplies solver_config without time_limit and omits task_data, task_data is None. Line 150 then raises AttributeError, and the server returns a 500 instead of a 400 with an actionable message.
🛡️ Proposed fix
if solver_config is not None:
if solver_config.time_limit is None:
+ if task_data is None or task_data.task_locations is None:
+ raise HTTPException(
+ status_code=400,
+ detail="task_data.task_locations is required to compute a default solver time_limit", # noqa
+ )
num_tasks = len(task_data.task_locations)As per path instructions: "Input validation on all fields from the REST payload" and "Error messages that expose internals vs. user-actionable messages".

32-32: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winPreserve regression coverage for the shared conversion imports.
The removed test was the only check that solver utility functions still resolve to the centralized conversion implementations. The retained test calls
conversion.populate_optimization_datadirectly, so stale or missing solver utility imports could go undetected. Add a behavior-level test for the solver utility import paths, or replace the deleted identity test with an equivalent contract test.As per path instructions, Python tests must include regression coverage for changed paths.

Move routing data creation routines out of routing solver.py so that they can be used in a proxy server that delegates solves to the gRPC server.
