Discovery effort and question choice
Choose investigations using their decision effect and supplied effort model.
Choose a question that reduces the largest remaining hypothesis set
Compare question partitions before spending equal investigation effort.
Know when pending observations cannot change an inquiry decision
Use finite bounds without claiming a population success rate.
Bound the effort an investigation could possibly save
Compare investigation cost with a perfect-information upper bound.
Check discovery coverage rather than counting conversations
Identify an unobserved operating role despite repeated interviews elsewhere.
Order feasibility checks by their expected stopping effort
A more expensive first check can save work if it stops unsuitable plans sooner.
