$$ Issue #269 retail slope-stop trace.
|
||||
$$
|
||||
$$ This script must only be attached to the Sept 2013 EoR acclient.exe
|
||||
$$ paired with refs/acclient.pdb (GUID 9e847e2f-777c-4bd9-886c-22256bb87f32).
|
||||
$$ The PowerShell runner verifies that pairing before attach.
|
||||
$$
|
||||
$$ It records the player object's complete physics-integrator boundary and
|
||||
$$ handle_all_collisions boundary as raw IEEE-754 bits. That is the minimum
|
||||
$$ runtime evidence needed to distinguish friction cadence, contact loss, and
|
||||
$$ post-sweep collision response without guessing from visible distance.
|
||||
