Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Handling refrigerants
Recovering, charging and repairing leaks in refrigerant circuits.
Still human-led✓ Evidence-backed
Where this applies
United States. The regulation says any person who could be reasonably expected to violate the integrity of the refrigerant circuit during the maintenance, service, repair or disposal of appliances containing regulated refrigerants must pass a certification exam. It binds people, predates current AI tools and says nothing about software.
What this means
Opening a refrigerant circuit in the US is legally a certified person's job.
What it does not yet show
A certification rule; it does not say how much of the work tools assist with.
What you can check
Open 40 CFR 82.161 on eCFR and find "must pass a certification exam".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
