re: the chatter phase merge is not additive; 224 authored variants never play

Browse Source 
sub_82215A58 reads CrewCount + PresetMessage_Phase1/2/3 and reaches the loader
from ONE call site, so the three phase tables fold into one map keyed by the
event record name.  Every merge collides; sub_82213840 reconciles on the
message list plus +16/+17/+18/+20/+24/+28 (NOT the +32 Yes mask), and the
incumbent always wins.  Measured: 26432 collisions, 26208 identical, 224
different (189 differ only in the message list), 0 mask-only differences.

Refuted handle: intersecting functions by the object's offsets finds dozens of
unrelated layouts -- offset shape is not an identifier.
