Research direction
Start by reproducing the reported SQLAdvisor case: a WHERE condition with selectivity 1 whose performance improves after adding an index. Trace how SQLAdvisor evaluates that condition and produces index optimization advice; done means the case is detected and the recommendation is verified against the observed improvement.
