James Dansereau 2e3d8be7e6 docs(D217): M-85 probe results — partial-count TLUT + stale upper palette
User confirms D217 is widespread (many levels, multiple weapons), not
Facility-specific. GE_D217 temp probe (reverted) shows GE weapon/character
model DLs issue partial-count G_LOADTLUT commands (count 1/28/125/172/193/
...); count=125 writes rdp.palette[0..124] and leaves [125..255] holding
the previous TLUT's entries, which differ per level. Weapon TLUT sequence
is identical BUNKER1 vs FACILITY (same PP7) + tiles import palidx=0
cache=HIT, so the delta is purely which stale upper-palette entry a weapon
CI8 texel lands in when it indexes >= its palette count. Root cause open:
CI8 decode reading past the base image (RC2/D183) vs GE relying on N64
TMEM-TLUT leftover semantics. Concrete next probes + a zero-the-tail
experiment noted in the finding. Wants a dedicated debug session.
