re: mining the base-solver index -- a false-positive mode named, and the AI-table reader found

Browse Source 
277 rows over 190 distinct functions (a function can read several blocks).
name_block_bases.py extended with a confidence split.

The tool's false-positive mode, measured and named: 107 of 277 rows solve to a
base on a 64K boundary -- a bare "addis rX, r0, 0xHHHH" with no addi, so any
scatter of displacements votes for it.  82 are 0x820B0000: about 60
near-identical functions in 0x8281xxxx-0x8284xxxx all "naming" the same rou_e0NN
list.  The 170 rows with a non-zero low half are the trustworthy set.  A round
base is not automatically wrong -- sub_822215D0 sits on 0x820A0000 and resolves
205/206 -- so read the ratio, not the base.

The index re-derives every loader we already knew (unit 217, stage settings 129,
PlayerParams 90, hangar 81, squadron orders, missile guidance, shell movement,
substructures, six camera/fog readers) -- that is the control.

The find: sub_8233C368 reads the AI behaviour table.  r28, base 0x8208583C, 20
names -- Enumerate_AIs, FiringLength, GuardLength, AutoGuardLength, CounterLength,
MusterLength.  stage-mission-tables.md owns those field names on the data side,
but Enumerate_AIs appears in no document and no reader was known; the corpus
carries the AI tail of Maneuver as NEEDS-HUMAN/runtime.  It is statically
reachable after all.  The same base also serves sub_82338EE0 (97 names, Weapon
TargetType SpecialWeaponType ReticleType IsCharging ...) -- the weapon datasheet
loader, also not previously named.

Five unowned blocks surfaced and NOT opened: PGHUD_*/PGREMAIN_NUM HUD part names
(205/206), STAGE_RESULT/stage_num_shoot_down_aircrafts/EX_OVERVIEW,
g_mWorldViewProjection/NormalMap/GlossinessMap engine material slots,
Boss16Collision* (cross-links the S16 Guardian object), and roh_n001_menu1_cam_pos
menu camera tags.
