Puzzle #504 - 24 Hour Puzzlers Club (Hebi)

I was fortunate enough to have the opportunity to contribute to the Puzzlers Club sets for the 24 Hour Puzzle Championship (full sets can be found here) in 2020. But, uh. We all know what happened in 2020, so the two round themes ("Hindsight" and "...is 2020") both turned out prettttttty appropriate, as the sets ended up getting used in 2023 instead.

I provided 4 puzzles, starting with this Hebi puzzle worth 30 points in the Hindsight round.
