- right-clicking a vendor with an item on the cursor sells it: `0x5df5d0` asks `GetCursorItem` before anything else and a non-zero answer takes the arm to `CMSG_SELL_ITEM` instead of `CMSG_LIST_INVENTORY`, where benilla sent the list unconditionally — the whole stack, to the clicked vendor, with no merchant-window gate anywhere in the arm; the clear is `SetCursorItem(0, …)` rather than `ClearCursor`, which fires `CURSOR_UPDATE` and leaves the source slot greyed until the server's inventory update (1914); and the NPC you are talking to is not clickable: `0x5f0130` refuses a right-click on the NPC whose window is already open, against a global with exactly two writers — the interaction setter, whose fourteen callers are every one a window opener, and its clear — so the first click always gets through and no double-click is eaten, where benilla re-sent the arm's opcode on every click (1866)
- a Hated or Hostile questgiver's `!` now disappears, every `!` blinks off and back on when you resurrect, and the minimap no longer dots a corpse, your own pet or an untrackable unit: the sweep tears down on HOSTILITY, not on the flag — `0x5eb134` is a convergent block reached from two branches, so three incompatible readings had each seen one path — and an escort giver's `!` clearing with its flag is the field watch instead, which B257 now rests on; the dots gain `0x4eaa90`'s three preconditions (1906); the quest log's rebuild is all-or-nothing — the reference makes every rebuild a no-op until its template misses are answered, so a cold log shows empty and then lands in one step, never our `"..."` row per in-flight quest — sorted level then title, case-insensitively, with the `id == 0` group first under the reference's own "Missing header! (quest designers)"; and `GetQuestLogTitle`'s `isHeader`/`isCollapsed` answer 1/nil, not booleans
- an animation event has a place, not just a time: the M2 event kernel (`0x719370`) places each fired key through its bone, and benilla carried the when and the what and never the where, so every animation-event sound played at the model root — 149 of 244 `$DSL` records sit off their model's origin, out to 67.6 yd on `Maraudon_Waterfall01.m2` — and the point belongs to the record, not the tag, since 75 models author one tag twice; doodad, GameObject and shake sounds now sound where the key is (1904); and the unit dispatcher's arms do not agree about the point they are handed — footsteps and emotes at the event point (the footstep's material foley stays at the origin), `$TRD` at the origin, `$CSD` at attachment 17 rather than its head-mounted records, `$CSS` at the event point on a hit and attachment 1 on a miss — with `0x623b90`'s attachment-else-bias resolver transcribed table and all (1915)
- `GetSkillLineInfo` out of range answers the reference's thirteen-value tuple, numbers in the rank slots, not a single nil — the stock skill window adds two of those slots unguarded straight off `SetSelectedSkill(0)`, so one nil raises the moment it drives us; one shape serves every out-of-range case because the bounds test at `0x4d3675` is a single unsigned compare, and our source had asserted the opposite (1919); the outbound wire is traced by name (`out`, mirroring `in`), a line pushed only after a successful write — a 5-second visit to the Goldshire poster reads as 87 lines (1901); the binding shape gate seats a player and checks the `Unit*` verbs it had been skipping, coverage 220 → 249, all agreeing with the reference (1911); and a UI capture scenario opts the UI in itself instead of photographing a UI-less world and exiting 0, the opt-in answering `false` in a player build that has no harness

- the GCD system now matches the real client end to end: opening a chest no longer eats the running global cooldown, and a running sweep's start stops wobbling between frames
- the mounted left shoulder's wild swing is fixed at the bone: a bone flagged to ignore its parent's rotation now does, decided before any camera-facing runs
- a gameobject effect with several animation sequences plays the right one: Molten Core's rune flame spreads and dances instead of collapsing into a bright dot
- the targeting cursor asks the thing under it and greys by default like the real client, and the ground-target reticle keeps its own location rules

- the loading screen now compiles every shader the world can reach: sky, water, spell shards and model variants stop hitching the first time they appear
- a locked chest's cursor carries the LOCKED word like the real client, and the lock verdict never leaks into the sent packet
- enchanting asks before it acts: a bind-on-enchant item gets its confirm popup, and so does replacing an enchant that's already there
- a long gossip menu scrolls like the reference with rows grown to their wrapped text, and music already playing is not restarted when the server re-sends it

- an item use is a real cast with an in-flight gate: the double-click never hides the bar and never ships a duplicate use
- the action bar answers both mouse buttons, and three more click-registration gaps are closed
- a cast right after a camera drag no longer dies to the position you already left
- landing while mounted keeps the gait's cadence, and particle clouds and ribbon trails sort correctly above and below the water surface

- ice block freezes the body the frame it lands, before the arm even rises
- the loot message links the item, so the name wears its quality colour
- a looted item drops into the bag that actually took it
- effect models live their authored life, born, held, decayed, and bar fills sit under their borders

- The keyring is built. Your first key makes the keyring button appear by
the bags, opening the window the original keeps its dungeon keys in — the
server had been sending the keys all along; nothing had ever shown them.
- Keys open their doors now. The client used to cast the open as a bare
spell, which the server rightly refuses; it now sends the item-use the
original sends, carrying which key from which slot. The tooltip plays
along: "Locked" turns the soft green when something you carry opens it,
and a key stops inventing a "Use: Opening" line it never had.
- A building can own the sky: a WMO can name its own painted skybox, and
Stratholme's burning city now draws its near-black-to-red dome instead of
the zone's khaki gradient. The exact rule for when it applies settles in
the next snapshot.
- Signpost tooltips follow the cursor again — the tooltip anchor forks per
object class, corner for doors, cursor for signs — and the Blasted Lands
lightning stops striking the same spot for ever: a placed doodad re-rolls
its animation variation every play-window, like the original.

- The dungeon framerate reports were right about the mechanism: the cost is
CPU-side and it scales with NPC count, not with what's drawn. Two per-unit
lanes were each 30–100x more expensive than the work they do. Measured at the
reported Lower Blackrock Spire spot: 29.7 ms/frame, 72 CPU ms, before.
- "Which room is this NPC in" scanned whole dungeon groups triangle by
triangle — a spire stacks several 15k-face groups into any vertical column,
so 37 moving NPCs cost 1.2 million triangle tests per frame. Each group's
faces now sit in a column index built at load; same verdicts (pinned by
exactness tests), 88k tests, the lane drops from 11.3 ms to 1.1 ms.
- Animating one creature cost ~190 microseconds per frame in generic per-bone
animation machinery — hash lookups and boxed curves per bone, mostly to
produce constants. A direct pose evaluator now does the same math into the
same joints for ~16 microseconds per rig, checked bone-for-bone against the
old output across crossfades, overlays and masks. The reference animates
every in-range unit with no view cull, and now so can we: a raid's worth of
animating rigs (~450) costs ~4 CPU ms where it used to cost ~85.
- Net at the reported spot: a flat 60 fps. The performance probes also learned
to report CPU work (ms and %) instead of wall-clock fps, which is what makes
these numbers repeatable on a busy machine — and comparable to the Mac
report's own units.

- Area triggers exist now, so portals work: every teleport pad, dungeon entrance
and enter-a-place quest volume reports the reference's own way — one exit latch,
first containing volume on the map wins, a sphere or a yawed box. Verified live:
Rut'theran to Darnassus, the Deadmines worldport, and a level-gated entrance
refusing with the server's own "You must be at least level 10 to enter."
- GameObjects animate. Every animated object arms its idle the moment it goes live
(doors and chests used to flash bind pose for a frame), a missing rest pose is
remapped the way the reference remaps it instead of playing nothing — the
Ahn'Qiraj gate's root tangle stood frozen for want of a Closed clip — and the
state machine covers the verified twenty of thirty-one object types instead of
three: fourteen hundred spawns' worth of traps, goobers, books and questgivers
now change pose off the wire.
- The flickering tent is still. Cloth you can see from both sides is authored as
two reversed copies of the same sheet, and the real client backface-culls each
copy from its wrong side so exactly one covers any pixel; we drew every building
batch two-sided, which left the winner to floating-point noise, flickering while
the camera crept. WMO materials now honor their cull flag.
- A sweep of long-standing visual bugs: effects respect the far-clip wall — a
ferry's deck lanterns were drawing from 7,000 yards away; the night-elf eye glow
goes out in first person instead of leaving two orbs burning in mid-air; the
goblins' stray white hair tuft is gone (a duplicated table key resolved last-wins
where the client scans first-wins); lava and slime finally have their own
submerged view — the dense fiery orange and dense green of the real thing, off
two fixed lighting rows nothing in the zone data points at; and the far-horizon
band overlaps the detailed terrain instead of leaving a strip of sky at lowered
view distance.
- Two caught at the keyboard: the backpack icon greys instead of vanishing while
the escape menu is up, and the world map is a real panel now — it can no longer
open over the menu, and ESC closes it first like everything else.

- The main menu bar's two empty recesses fill. The micro menu — the eight arched
buttons: character, spellbook, talents, quest log, socials, world map, main menu,
help — sits in the dark panel between the page arrows and the bags, transcribed
from the reference's own layout: the character button wears your portrait, a button
holds itself down while its panel is up, and the talent button appears at level 10.
The latency meter fills the one slot the bar art leaves transparent for exactly it,
tinted green/yellow/red on the reference's 300/600 ms thresholds and drawn UNDER
the bar art, seen through its window, the way 1.12 actually does it. The socials
and main-menu buttons find their panels one snapshot later; help still waits.
- The UI explains itself on hover: 1.12 ships its detailed two-line tooltips ON — a
FrameXML default, not the opt-in extra it is often remembered as — so the micro
buttons, your own portrait, the XP bar, the five bag buttons and the ping meter
all answer a hover with the reference's own explanations.
- The PvP flag, end to end: crossed swords on the player, target and party frames,
driven by the two descriptor bits the wire actually carries, and `/pvp` speaks —
the yellow toast plus the system chat line, the OFF sentence being the one that
warns the flag lingers for five minutes. It really does linger: turning it off
waits out the server's timer, which looks like a bug and is the reference.
- Quest markers stopped freezing. The grey `!` over a questgiver above your level
goes gold the moment you ding, an NPC re-entering view is asked afresh instead of
wearing a session-old answer, and the marker drops when the questgiver bit goes
off — the re-ask triggers mirror the reference's own set, plus one named addition
(your own level changing).
- Water and heights: swimming downhill no longer bounces between swim and fall ten
times a second — the surface line is a two-sided constraint, so the swimmer
settles with the river instead of being left behind by it. And collision height
is per-unit now, read from the unit's own model: a gnome used to swim with a
third of a yard of water over her head because five depth lines were quoting a
human's number.
- A round of pixel honesty in text and chat: the newest chat line no longer wears a
wider drop shadow than every line above it (shadows move in whole pixels now),
keeps its descenders, and hover boxes stop painting over the chat body. The chat
input's history browse survives programmatic edits, a failed script chunk warns
instead of vanishing, and recall deepens to 64 lines. Idle animation got honest
too: a model's idle is Stand resolved through its own lookup table — never
file order, which had the duel flag bobbing on its spawn clip — and an armed idle
is culled on the box its animation authors, not the bind pose, so the flag stops
vanishing at most camera angles.

- Duels. Challenge another player from their right-click menu, or with `/duel`, and
`/forfeit` to give it up. Both popups are there — the challenge you accept or decline, and
the warning when you leave the field — with the flag countdown between them, and the outcome
printed in chat when someone is knocked out or flees. Read off the reference client's own
duel packets and the three globals it keeps client-side, which is why the challenger reads
"You have requested a duel." even though the server never echoes that back.
- Inspect. Right-click a player and open their paper doll: their nineteen publicly visible
equipment slots with icon, name, quality and a linkable item, and their body standing in
the pane, which follows along if you retarget while the window is open. No stack counts and
no durability — those are not fields another player publishes, which is exactly why the
reference client's inspect doll has never shown them either.
- Water knows where it stops. Swimming used to trigger in the dry tunnel thirty yards under
Stormwind's canal, and in mid-air over Blackrock's lava. A liquid is now the grid the map
file actually stores — one wet flag per cell, and the surface height a bilinear over the
four corners of the cell you are standing in, the same sample the reference client takes —
so the water starts at the bank and its surface sits where your eye puts it. Lava is a
liquid you swim in, an indoor liquid asks the building you are inside, and `/liquid` prints
every surface claiming your feet and where each one came from.
- Creature parts authored to appear only on death — the voidwalker, the banshee, the ooze,
the stone elemental, the infernal — were drawing the whole time: material alpha now bakes
per animation sequence and the unit lane actually evaluates it. The character and inspect
model panes are lit by the reference widget's own single light instead of blowing out white,
the rotate arrows spin while you hold them, and the transparent sort ladder had its sign
backwards, so overhead names draw over water again instead of being painted out by a canal
behind them. Underneath, the protocol writer's 95-verb drawer and its thousand-line spell
module split into per-family files — no behaviour change, just a tree you can find things in.
