TTT Day 1 — Case 2 — 50yo screening positive (Luigi / Nick / John)

50-year-old screening positive, propofol. Luigi (very experienced Italian fellow) — Nick's job is to push conscious competence, not teach scope skills. "Problem → solution → execution" (PASE) decision-analysis frame introduced. Retroflex-on-the-way-in, water immersion insertion, textbook N-spiral loop resolved with clockwise torque. Nick's super-trainer review with John drills the failed "innominate grooves" reference and how to detect when a trainee hasn't truly understood.
