Phase C palette extraction — evidence
|
|
=====================================
|
|
|
|
Conclusion: libcxsdk.so has NO static palette tables. A full-file scan for
|
|
256 consecutive u32 LE entries with alpha=0xFF and non-zero RGB finds 0 hits
|
|
(also 0 with alpha=0x00, and the BGR/RGB triple forms). CFunctions::
|
|
SetColorPalette builds the palettes with arithmetic at runtime.
|
|
|
|
Validation chain:
|
|
1. port reproduces OfficialTables.PALETTE256_ARGB 256/256 (iron bow)
|
|
2. every case writes all 256 entries exactly once
|
|
3. colour coverage of the official APK preview mipmaps:
|
|
|
|
palette colors own case best other

white_hot 211 100.0% 100.0%
|

|
|

|
|
hot_metal 482 42.1% 11.0%
|
|
jet 1251 14.0% 4.7%
|
|
red_saturation 660 26.7% 22.1%

|
Notes:
|
|
- red_hot: the official preview asset is a stub (137 of 11914 pixels differ
|
|
from palette_white_hot.png), so it carries no palette information. No
|
|
generator body is claimed for UI index 11; Palettes.kt keeps its
|
|
approximation with an explicit comment.
|
|
- cases 12 and 13 exist in the native library but explain no official
|
|
preview (best 3-6% against jet); they are not among the 12 UI palettes.
|
|
- the previews are scaled photographic crops, so absolute coverage is low
|
|
for some palettes; the correct body always wins by a wide margin.
