Thanks to all who responded, which helped me determine
the problem was cooked (multiple solutions).
Simplicity provided a valid solution, and some Fluffy cat
who writes with white crayons may have too (LOL, maybe
I'm dense, but I couldn't figure out how to read it).
My intended solution (North leads
♣A):
The curious 5-card ending was new to me, and I'm not even
sure what to call it. The squeeze is saturated (threats in 4 suits),
progressive (gains 2 tricks) and double (both opponents), so
"saturated progressive double squeeze" would be my guess.
I'll try to reword my conditions to yield only the above unique
solution. (Note that Simplicity's solution could not be unique as
his "finessing" cards could be any suitable spades.)
