"BooleanDifference" challenge

looking for help on how to trouble shoot “BooleanDifference”. common failure modes would be someplace to start if there isn’t a standard trouble shooting regimen. more specifically any help understanding why ALL but one of the pockets subtracted per plan and this one is having none of it would be greatly appreciated. the pocket has been recreated and there was NO change…

Use a reasonable tolerance, like 0.001 and it works correctly. Your tolerance of 0.000001 is rather extreme considering the edge tolerances in the input are 100 times that.
