Research direction
Start by locating the presolve logic that determines whether a model is feasible. Check how models with no constraints are represented and how feasibility is currently recorded. Done means a constraint-free model is marked feasible during presolve, with existing tests or a new focused test confirming that behavior.
Written by the indexing model from the issue text.
Description
Currently there are no cases where we mark a model as being feasible. However, we could/should in the case that the model has no constraints.
