常见的想当然

A `checked(:never)` method in a class with duplicate `method_added` hooks still incurs wrapper allocations on every call.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• A method annotated with `sig { returns(Integer).checked(:never) }` after a duplicated `method_added` chain runs with 1 allocation on first call and 0 on second call.
• The second invocation must stay allocation-free after first successful call, proving the wrapper is not dropped by a second `_on_method_added` event.
