re: the base-solver -- 277 name-block loaders indexed, and the analog block is SOLVED

Browse Source 
New reusable tool, tools/re-capture/name_block_bases.py -> docs/re/data/name-block-bases.txt
(2880 lines, ~65 s, byte-identical across two runs).

A loader that reads a table by field name keeps one base pointer and emits
"addi rX, rBASE, -N" per name, so no static xref sees the strings.  Solve the base
from the DISPLACEMENT SET alone: every (string address, displacement) pair implies
a candidate base, and the true base collects a vote from every name it explains,
so it wins outright.  My first cut took candidates from ONE displacement and
scored the unit loader at 52/226 against the right answer's 217/226 -- vote over
the whole set, not a probe.

Control passes with no prior knowledge: the tool recovers sub_82341A20 -> r30 =
0x82088F94 at 217/226, and independently recovers sub_8230D1F8 (129/132),
sub_822F9498 (90/91) and sub_822AE628 (81/108).  277 name-block-reading functions
image-wide, with the schema each names.

The analog block is SOLVED: sub_821A6CF0, r29 = 0x820A1630, 22/24.  In code order
it names ControlTweakName, YawMagForNormal, the 12 Tweak fields, the 8
AnalogRevice_* curves and GP_MAIN_GAME -- the whole schema in the object's own
order plus its pak.  r29 is built at 0x821A6D34 as addi r29, r11, 5680 =
0x820A0000 + 5680, matching the solved base exactly.  It is the same function that
reads PlayerParams.

Two of my own verdicts withdrawn: "referenced by nothing" and the softened "not
found by these routes".  The measurements behind them were right; the conclusions
were wrong.  The base was solvable from the data the whole time.
