TTT Day 1 — Case 4 — SC2 scar follow-up (Adam / Beth / John)

53-year-old SC2 site check; previous 35mm adenoma resected 2024 with CAST technique. Adam (second case of the day) under sedation — awake, French-speaking patient. Contract: loop avoidance, slowing down, position change, fine tip control. Includes N-spiral roll-to-back, water vs CO2 switching at splenic, and John's mid-case redirect to an underwater view of the scar from the right side. John's feedback: "control the trainee, not the scope" message; splenic-flexure algorithm laid out.
