Case 150 — Crown operation: when a forum cannot diagnose the resistance · uncertainty exercise
A description of stiffness does not establish the cause. What information is safe and useful to collect before an inspection?
Review focus: uncertainty. Leave the unresolved part visible instead of supplying a result. Use the original answer fragment “Describe whether resistance occurs during winding or setting and…” as the discussion anchor; no new event or result is supplied.
Exercise RWI-25905/150: address this question within its stated limits.
