- 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
