Spec compliance review on T10-T12 bundle (commits 0cf86bb/00bb030/0405947)
caught 2 unprotected dat reads that the original T10 audit missed:
- GameWindow.UpdatePlayerAnimation (line ~7546): reads Setup when the
player entity is missing from _animatedEntities (post-respawn pattern).
- GameWindow.EnterPlayerModeNow (line ~8567): reads Setup when entering
player mode to derive StepUpHeight / StepDownHeight from the dat.
Both run on the render thread post-_streamer.Start(), so they can race
with the worker thread's BuildLandblockForStreamingLocked. DatBinReader's
shared buffer position would corrupt — same class of "ball with spikes"
bug the original Phase A.1 hotfix addressed.
Wrap both reads in lock (_datLock).
