Sylpheed RE agent f59c4e595c re: refute my own position anchor, withdraw the entities2 "defect", find the trap
Three results, two of them against my own earlier claims:

 - REFUTED: position = instance - 0x12c.  The corpus anchors on position (def ptr
   at +0x130, orientation at -0x70, hull at +0x154) and name_of reads the def ptr
   at instance+4, which predicts -0x12c.  Measured over all 42 named instances:
   almost every read is (0,0,0), three are garbage, and 0/42 move.  The vtable
   object and the position block are different structures.

 - WITHDRAWN: last iteration's claim that entities2.py's ENT_VA window is aimed at
   the definitions rather than the instances.  entities2 does not look for vtable
   objects at all -- it hunts moving position triples and checks +0x130, the
   documented anchor -- and it had worked minutes earlier (6914 movers, +0x130
   voted 92x; then 6634/138x).  I built the defect report on the single sample in
   between that returned zero.  The +0x29d0 position candidate falls with it.

 - FOUND: sampling 64 spots across the 505 extents (357 MB) twice, 2.5s apart,
   with the mission visibly running, only 5 change.  The megabyte holding all 42
   instances is byte-identical over seconds, as is its primary-VA counterpart.
   The mapping IS live (5 regions prove it); what is undetermined is whether the
   entity records are simply static or whether writes land in a different alias.
   Either way: verify a region changes before measuring through it.
