Sounds like a fun puzzle, but a single‑shot zero‑delay thing? We’ll need a cascade of gates wired with no flip‑flops and a perfectly timed clock‑free latch—basically a pure combinational tree. The trick is to flatten the 10 layers so each intermediate result is a direct function of the inputs. We can do that with a giant AND‑OR‑NOT mesh, but any typo and the whole thing collapses. I can map it out in a few minutes, but let’s double‑check every line before we hit that “one‑second” target—any chaos and the whole plan goes south. Let’s get those truth tables ready, and we’ll debug in the smallest increments.
