Subject: [PATCH] knockback is a jump the server aims, and tabards wear their
 guild crest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- knockback is a jump whose seed came off the wire, not a server spline: SMSG_MOVE_KNOCK_BACK's four floats are exactly the MovementInfo jump tail in a different order (speedZ down-positive — a rising launch carries a negative value, the sign vmangos's own source marvels at), flown at the same take-off site as the keyboard jump and acked with the post-launch pose, which the server matches float-for-float within 0.01 before relaying to anyone; it is the one take-off that seeds BOTH axes, absolute in world XY, so it skips the arm that would hand the momentum back to a held key and reduce the whole knockback to a hop; root refuses it silently, a seated player stands up first, no MSG_MOVE_JUMP goes out — that packet is the keyboard's, and vmangos logs a jump at knockback speed as an overspeed cheat — and MSG_MOVE_KNOCK_BACK turns out not to be dead: an observed knockback replays as the arc it is
- your guild crest reaches your tabard: the three GuildEmblems layers — background, border, emblem, on both torso tiles — belong to no equipment slot, so the body composite never wrote those cells and every guild wore the Guild Tabard's own default art; the install is gated on a display flag only seven of 29,604 rows set, of which exactly one is worn by any item — which is why every battleground and Argent Dawn tabard keeps its own art; the five wire indices are signed, because an undesigned guild carries −1 in all five and the client refuses to paint on the first −1 (unguarded, the commonest guild state on a young realm would have worn a blank tabard); the emblem keys the skin cache, so two guilds in the same tabard display cannot lend each other crests; and a guild tabard's background hides the bra where a plain tabard does not — it is a cutout, 79.5% opaque off the shipped art, and what shows at the sides is bare skin
- a fly-by is framed by the world camera, not the M2 camera record's fov: a census of every reader shows the record's fov and clip planes reach only the portrait and Model-frame paths — nothing on the cinematic path reads any of the three — so fifteen of the sixteen shipped shots were rendering at HALF their intended vertical FOV, visibly over-zoomed on every race intro but the Undead; the fix is a deletion, and it dissolves a standing puzzle: the authored 0.22 and 27.8-yard "clips", which would render the dwarf intro's mountains as empty sky, are not clips at all on this path — two floats nobody consumes look exactly like that
- 104 of Onyxia's lava traps stood on an interior floor classified as outdoors, taking the day/night sun inside a windowless lair: a GameObject's light node anchors at its model's AUTHORED bounding-box centre, and the trap's box reaches 98.42 yd past its bind pose — the anchor sits ~40 yd under the chamber floor, where a downward ray finds nothing above it to claim; the reference recovers with a 1000-yd upward retry at the claim itself, which benilla had only at the colour sample, so the verdict was decided before any colour was read; all 104 now classify interior, beside the 26 rocks and 119 eggs that always did — and the drowned-corpse pose came back from its cross-check confirmed at the bytes (a strict liquid-depth test at exactly two-thirds of a yard, Dead or Drowned), with the two reference-side notes it contradicted corrected over there

+//! which is reachable solely from the portrait and `<Model>` frame paths. **On the cinematic path
