--[ Challenge Description ]--
-- text --
I turned my *ELF binary* into a pickle, Morty!
Note: not related to the python pickle library

--[ Recon / Initial Analysis ]--
This page imports the BYUCTF 2026 source material for the Reverse Engineering
challenge Pickle Rick. The prompt is kept separate from the solve notes, and
upstream artifacts are linked so the challenge can be replayed from the original
repository.
────────────────────────────────────────────────────────────────────────────────
--[ Vulnerability / Observation ]--
The useful observation comes from the imported solve notes below. I kept the
original technical path intact while normalizing the page metadata, challenge
grouping, and author attribution for the Volume 2 writeup archive.

--[ Key Takeaways ]--
- The BYUCTF 2026 challenge material is preserved with local archive formatting.
- The page author is normalized to Imattas aka Zemi.
- The source repository remains linked for handouts, services, and solve
artifacts.
