Splitting every unnamed entry by magic turns the coverage percentages into an explanation. The three low-coverage UI archives have ZERO unnamed IDXD. GP_HANGAR_ARSENAL is 180 IDXD, 180 named, 0 unnamed -- its 1191 unnamed entries are 1149 T8aD/RATC plus 42 LSTA, i.e. sprites. GP_MISSION_SELECT and GP_DEBRIEFING_PILOTLOG hold no IDXD objects at all. So "22.6 % named" is misleading: every data table in that pak is named, and these three are the same artwork-naming phenomenon as the blocked 2D and READY_ROOM archives. DefTables is the only genuine data gap: 1425 IDXD, 130 named, 1295 unnamed, in 17 record-name shapes -- Generic + Level_0..Level_3 (807, LOD sets) and Default + EnumMotions + Generic + ReferenceFrames +/- Motion_break/dead/down (463, motion sets). One LOD and one motion table per model. Level_0, EnumMotions and ReferenceFrames appear in no document. Control: the 100 % archives have no unnamed entry of any kind, and GP_MAIN_GAME_E is 667/337 IDXD with zero unnamed artwork -- two failure modes, not a gradient.
