Problem
In src/CubeFactory.cs, the removal branch looks the element up by index and then removes it by value:
// remove oldest cube
GameObject oldestCube = cubes[0];
cubes.Remove(oldestCube);
Destroy(oldestCube);
List<T>.Remove performs a linear scan for the first reference equal to oldestCube, even though the index being removed is already known to be 0. cubes.RemoveAt(0) expresses the same operation directly.
Equivalence note
The two forms are equivalent only if the list can never hold the same reference twice. Every entry is added from a distinct Instantiate(cubePrefab) result, and nothing else writes to cubes at runtime, so duplicate references cannot arise through the component's own code path. cubes is a public serialized field, however, so a consuming project could in principle populate it by hand in the Inspector — that possibility is worth the owner's consideration before the change is made.
Suggested resolution
cubes.Remove(oldestCube) should be replaced with cubes.RemoveAt(0), and the local oldestCube should be retained so the reference is still available for the following Destroy call.
Verification note
This is a change to executable code in src/CubeFactory.cs. Although it is intended to be behaviour-preserving, confirmation requires a play-mode run in the Unity Editor; no such run backs this report, which was derived from reading the source.
This issue was drafted during a Gardener session (https://github.com/Stephenson-Software/gardener).
