- the action-bar cluster is the reference's own: `MainMenuBar.xml`, `ActionBarFrame.xml`, `MultiActionBars.xml` and `BonusActionBarFrame.xml` run off the player's own chain, and our `ActionBar.xml` (2047 lines), `MultiBars.xml` and `StanceBar.xml` are deleted — three, since the stock bonus-bar file declares the shapeshift bar too; one engine verb, `ChangeActionBarPage`, fires `ACTIONBAR_PAGE_CHANGED` and nothing else; one load blocker: stock `MultiActionBars.lua` writes the options window's table from its OnLoad, the reference's own load-order hack, so our options window moves to the reference's toc slot; and ten things the reference does that ours did not: an empty button is HIDDEN while showgrid is 0, the bonus overlay sits one pixel right of the main buttons, every slide takes one frame more than its time, and `ActionButton_ShowGrid` ghosts EVERY ring, occupied included (1938)
- a gift can be wrapped: right-clicking wrapping paper fell through to plain use and sent `CMSG_USE_ITEM`, so nothing happened — you could receive a gift and never give one; the wrap is a displayed-cursor MODE plus a stashed slot, never a payload, so `CursorHasItem()` stays false and every stock gate on it stays shut: right-click arms it, a left-click on a bag slot sends `CMSG_WRAP_ITEM`, and the client applies no eligibility test — the server's `ERR_CANT_WRAP_*` reasons are the error line (1934); a duration-limited item counts down: `SMSG_ITEM_TIME_UPDATE` parks a deadline and the tooltip's `ITEM_DURATION` line runs the enchant countdown's bucket ladder, so "Duration: 1 days" is what the reference renders; an update for an item we do not hold is DROPPED, no queue (1933); and a renamed crowd-control refusal names its mechanic — "Can't do that while stunned" — off `SpellMechanic.dbc` (1943)
- a creature paths on a boat: `SMSG_MONSTER_MOVE_TRANSPORT` carries the transport's guid and deck-local coordinates, and is the attach/detach edge; a deck sample lands on the rider or nowhere, never as a world write a few yards from the map origin; and "there is no terrain under a boat" turned out wrong: the ground probe admits GameObject meshes — a boat's `.wmo` is a GameObject, so the probe hits the deck (1936); `MSG_MOVE_TIME_SKIPPED` is read, not dropped — the reference adds the lag to the observed unit's last-wire stamp, so dropping it scheduled their next packet `lag` ms late, a hitch for every player who stalled zoning in near us; and our own settle hold reports once (1935); and the tradeskill tool order was backwards — focus FIRST, so every two-tool recipe had read "Blacksmith Hammer, Anvil" for the reference's "Anvil, Blacksmith Hammer"; the focus's `hasTool` is 1.0 in the reference too (1942)
- the crowd's second sitting, instruments first: the probe line carries the tail — cpu p95/p99 and the six worst frames — because a mean under budget hides the one frame in twenty over it (raid legs railed at 16.67 with p95 at 18–20 ms) and whether that frame was work or a wait is the first question about a stutter, and the visible meshes are counted by lane; then two cuts — a terrain tile furnishes as 4×4 cells of 4×4 chunks, one mesh, one entity, one draw per 133-yd cell instead of per 33-yd chunk (a city horizon is over a thousand chunks a frame, and a cell changes nothing a pixel can see; Stormwind 10.55 → 10.32 `cpu_ms`), and an authored point light is our own `WorldPointLight`, not Bevy's `PointLight`, which was only a data carrier while Bevy ran its whole light lane over every lamp, ~2 % of the alone frame; the sitting's record is 1945, and the code says so (1945)
