re: the AA_/AV_ selection is BLOCKED for static RE, with the mechanism

Browse Source 
Route 3 (call-graph bound): sub_821A6CF0 and sub_821AB650 each read 196/200/204
off THREE different base registers -- three unrelated objects, not the block.

Route 4 (data-flow bound): the definition object lives in the global at
0x828F358C; 18 functions touch it, 9 also touch block offsets.  The two best
are refuted -- sub_8230D1F8 is the rank/score loader storing
CraftScore_Adjustment, FFPenalty_Zessel_Maximum and RankScore_S/A/B at exactly
256/320/324/328/332, and sub_82398CC0 uses r19 as a float-constant pool.

So the offset region is shared by two unrelated objects and a constant pool:
offset-based discrimination is contaminated by construction, which is why it
has now failed three times.  Catching the selection needs a runtime watch.

Side finding, unowned by the corpus: sub_8230D1F8 is the rank/score loader.
