Savestate slot 2 is the second planet, so the comparison runs on a level with
a different geometry extent, light bank and runtime-set population:
level1: 401/401 headers, 401/401 pointers, bank byte-identical
vertices compared: 26470 (105880 colour bytes) -- equal: 100.00%
The live emulator agrees with the savestate byte for byte. Level 1 is a
different planet, so the two fixes in the previous commit are not level-0
coincidences: the normal's z sign and the unlit-record base colour both hold
across 268,280 colour bytes on two levels.
