- a quest objective that carries both a creature and an item is two lines in the quest log, as the reference's four passes enumerate it: Graverobbers shows its Embalming Ichor (2249) - the quest log's detail follows the live selection inside a frame, so a quest addon's log walk reads the right quest; Questie no longer files a chain quest under its shortest sibling (2247) - a UI tint change is not a material change: a run's colour rides the batch's instance tag, so the PlayerFrame glow no longer re-prepares a material every frame (2245) - the workspace lints clean on rustc 1.98: constant-size chunks become as_chunks, one slice fill, two unused globs - WOW_HOVER_PROBE aims the pick in a headless run, and the inspect card names the tooltip's ladder stage (2248, 2250) Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

//! `Interface\WorldMap\<Continent>.zmp` — the continent area bitmap: a 128×128 grid of
|
||
//! `AreaTable.dbc` row ids (16384 little-endian u32, row-major, exactly 65536 bytes) covering the
|
||
//! whole 64×64-ADT world at half-ADT granularity. The client's world-map hover/click resolves a
|
||
//! cursor cell to a zone through it (`0x4a6ec0`; the loader `0x4a5d00` remaps cells to
|
||
//! WorldMapArea ids at load — benilla's remap lives with the catalog build, `ui_world_map`).
|
||
//!
|
||
//! Mechanism VERIFIED by wow-re (Q1 §5 cross-check, 2026-07-07, recorded in
|
||
//! `system/ui/scratch/geometry.md` "Worldmap data model"): path format string @0x845374
|
||
//! (`Interface\WorldMap\%s.zmp`, `%s` = the continent WorldMapArea row's AreaName), 0x10000 bytes
|
||
//! read raw into the record. Corroborated against the shipped file this session: Azeroth.zmp's
|
||
//! cell at the recorded index law for Goldshire's world position holds 12 = Elwynn Forest.
|
||
//! 5875 ships `Azeroth.zmp` + `Kalimdor.zmp` (and a dead `Expansion01.zmp`).
