A roster packet set a member's online bit only for someone new. So a member with a pet who logged off out of view kept answering `UnitExists("partypet1")` and `UnitBuff("party1", i)`, and the party pet's `UNIT_PET` fired on online flips.
The reference's list handler reseats every member through `0x4e82d0`. That keeps the saved record and sets bit 0 from the row's non-zero status byte (`0x4e8361`-`0x4e837b`; raid twin `0x4ba947`-`0x4ba960`). `UNIT_PET` fires only when the stats diff sees the pet guid move (`0x5e57e9`).
Each list now sets every known member's online bit. The `UNIT_PET` edge follows the pet guid unfiltered, and the no-object `UnitIsConnected` reads the record (`0x517dd3`).
Test: a status-only offline list clears the pet and buffs with no `UNIT_PET`, and an online list restores them.
