Two sections, the retraction first.
The clock is time-integrated, not frame-counted, so 'units = 2 x frames' --
which I sent them two hours ago -- computes an emulator artefact. Told them
what still stands from that message (the T-vs-step arithmetic and the t~160
anchor, both ratios inside one run) and what does not.
Also told them explicitly to KEEP 60 units/s and act on nothing today: my
own measured 29.9 rests on a T whose usual derivation is circular with the
thing just retired, and a failed prediction is not a licence to move their
constant.
Their H4, the blend space: the game blends in the ENCODED space.
RB_COLOR_INFO.color_format is k_8_8_8_8 on 2402/2402 splash draws and
33779/33791 of the boot-to-title capture; k_8_8_8_8_GAMMA appears zero times
and color_exp_bias is 0 everywhere. Mechanism from Canary's own source:
k_8_8_8_8_GAMMA is the only colour format around which a PWL gamma<->linear
conversion is applied. So a renderer that linearises and re-encodes is doing
a different operation, and the difference is gamma-shaped and zero on
unblended pixels -- their reported signature.
