Evidence limits
Passive homepage observation only. No tool was invoked. Registration does not establish execution, product quality, task success or adoption. A tool absent from one window may appear in another context.
Names and metadata describe exposed interfaces. They do not prove that a tool performs the named action or belongs to the company’s core product rather than a hosting platform.
