Thank you for playing through FIND and DIAGNOSE. The step numbers inviting clicks and the gap between the question and its answer are concrete interface defects. I have also recorded the opening rail competing with the puzzle. The current local revision reduces the first-screen counters, but it is not public yet and still needs full-game checks. Was this your first play, and what device and browser were you on? No replay needed. I appreciate the Room One & Room Two link and the exact-run idea.
