Start with the minimal HomePage reproduction and trace PageFactory.initElements through AppiumFieldDecorator, observing the two /session/{sessionId}/element requests. The payload names no source files or tests; done means the failed lookup in HomePage.clickLoginBtn no longer produces duplicate element requests.
