🦋 Members 🦋

✨ the field-by-field vibe check ✨

• zt — Zone Type. literally which flavour of zone this is 💖
• zs — Zone State. the zone's current mood, fr fr 🌈
• za — Zone Attributes. the lil extras it's carrying around 🎀
• zai — Zone Attributes Information. the ✨info✨ about those attributes, iykyk
• rsvd4 — Reserved. not for you, bestie 🙈 hands off
• zcap — Zone Capacity. how much it can hold, lowkey the important number 👑
• zslba — Zone Start Logical Block Address. where this zone begins, exactly, no cap 📍
• wp — Write Pointer. where the writing is currently at 🔥 main character of the write path honestly
• rsvd32 — Reserved. also not for you 💀 stay out of it

no cap on any of this — every single member is listed, every single one is accounted for. the reserved fields stay reserved. that is not a suggestion, that's the rules 💅
