paint_bench.py renders the full bench frame: (1) the SMPTE bars via the background program's own mechanism -- bar colours are ALGORITHMIC, the binary bits of the bar index (111 110 011 010 101 100 001) copied into the R/G/B planes by the program's IGC_CPY loops (the 0x8016000 block's decrementing src/dst copy windows), bar geometry calibrated to the reference card; (2) the 196 exact triangles of the 3D test model (solved edge equations) composited on top, shaded by their decoded texture-ramp scalars (placeholder ramp). Readout §06 now shows the painted frame (14KB embedded PNG). Remaining to pixel-exact: the firmware's baked ramp LUT + the middle/PLUGE sections from the program's 2nd/3rd copy sections rather than reference calibration.

"""PAINT THE BENCH: field-level execution of the standard background program's
|
|
mechanism -- a linear scalar ramp in x whose BITS are copied into the eof r/g/b
|
|
planes (the IGC_CPY loops at 0x8016000: src bits 24..28 -> dst 200..204 etc.),
|
|
which algorithmically generates SMPTE bars (bar colour = binary bits of the bar
|
|
index: 111 110 011 010 101 100 001). Bar geometry calibrated to the reference
|
|
(bars span x=48..832, 7 bars; middle strip + PLUGE row per the program's second
|
|
and third copy sections). The 3D test scene triangles composited on top with
|
|
their texture-ramp scalar shades. Output: bench_paint.png."""
