okay so every field, one by one, with the exact spec wording so you don't get ate up in review:

• opcode — command to perform B-0 🦋
• idn — a value that indicates the particular type of data B-1 💜
• index — Index to further identify data B-2 🌸
• selector — Index to further identify data B-3 ⭐
• osf3 — spec field B-4
• osf4 — spec field B-5
• osf5 — spec field B 6,7 (yes, that spacing is canon, don't come for me 🙈)
• osf6 — spec field DW 8,9
• osf7 — spec field DW 10,11

ngl the osf names are just "spec field" placeholders — that's literally what the page says, so pls don't ask me to invent meanings, i would never lie to you like that 😭
