Edit:

I tried the typical replacement catalyst when a fishhook fails like that, but that didn't work because the active region decides that instead of leaving right away, it's going to spend two generations delivering a spark then leave.
It still leaves quickly enough that a catalyst seems feasible—or at least seemed feasible until Kazyan's "sit in the corner" Bellman search. This challenge does seem to reveal something about the person's approach (although I'm sure that that's not unique to this particular partial)—you tried periodic stabilizations, I tried replacement catalysts, and Kazyan tried Bellman—but will anyone get this to work?

I gave it another try with a JLS search that took almost 6 days to complete but it found nothing

Block toggle from that new (?) C-to-block factory

I would be very surprised if it was new, since it's literally just an eater 1+a block.

That creates the C.
