Clarifying response and flag format

I’m thinking the user likely expects the flag, especially since they've included the format. I could mention that I’ve found the flag format for the first challenge and that I don’t have enough for the second one yet. I should keep it concise and avoid any citations unless absolutely needed. Clarification from the user might help, but I’ll focus on the first flag for now.

For The_L0ng3st, divide the hex into two equal 96-character chunks; they’re identical and match the SHA-384 length.

Flag:

text
0xV01D{sha384_sha384}

For Buried Session, I found the buried structure in the uploaded artifact (500 random bytes + 333-byte middle + 500 random bytes, with PUZZ inside the middle), but I’m not confident enough in a recovered flag to suggest submitting one for that 3-attempt challenge.
