this reminds me of the "what is a step" exchanges for the inferior thread

it took a while to reach consensus

my solver can select and order the techniques applied and apply the techniques when hit

or batch them by group -- there is an option combination to match "step counting" for

the { inferior superior ulterior } threads and I'd like to determine a similar characterization for this thread

submitting puzzles one by one to an oracle for a binary yes/no may be fun for some, but not me

could you post the techniques applied to arrive at the solution for the two puzzles you cited?
