Owner

From the LL-origin inefficiency audit (finding A17). File/line references are from commit 0229f8872c; re-locate them before working.

Minor per-frame items

getSelection() twice per avatar plus cleanupNodes (llvoavatar.cpp:2940)
checkTextureLoading loops forever if one texture never resolves (:5826-5838)
getJoint(S32) attachment map find inside the calculateSpatialExtents loop with a dynamic_cast per joint (:6533, 1544-1560)
getOverallAppearance 4+ times per avatar per frame
Dead: mMatrixPaletteCache (keyed by colliding mHash; delete), idleUpdateWindEffect (a no-op)

Verify the cost (profile or timer) before and after changing it.
