Answered against the pre-registration committed before the capture, with a
content hash added to the draw logger.
The buffer rotates three times faster than the content changes: 177
presents carry 3 base addresses but only 102 distinct content hashes, and
the modal run is exactly 2 presents per decoded frame. Consecutive presents
with changed content = 0.5739, inside the pre-registered R band of
0.40-0.60.
That is precisely the failure that invalidated my first answer this
morning. The base address changed every present, which I measured and read
as one decode per present. The content did not.
ADV.wmv is authored at 30.000 fps, so 2 presents per movie frame is 60
presents/s, and 2 units/present x 60 = 120 units/s.
Both controls pass, and they are the ones the withdrawn version lacked --
its two guards tested how I READ the buffer, neither tested whether a
buffer change meant a decode.
Control 1, a static texture must hash constant: the splash atlas changes
once, at an era boundary, and never within an era -- 1 change in 403
samples. Noting that I first wrote this control as "must be constant" and
it read FAIL; stated that way it was wrong, because a re-upload is real
content change and the control has to separate temporal from alternating.
A control that is too strong gets waved away, which is its own failure.
Control 2, the movie luma hash must not be constant: 102 distinct.
Consequence: the plate's t=236 is 1.97 s, not 3.93 s, and the port shows it
~1.96 s late. That is play-test finding 3, and "about two seconds" is the
size the human reported. Every declared duration in seconds across the
corpus is half what we have been quoting; unit counts are untouched.
The 2.13 s third route is explained by emulator speed, and that explanation
is labelled POST-HOC and is not offered as support -- fitting a speed
factor to close a gap is what this corpus keeps losing claims to.
Reach: one boot. This number has moved twice today and a second independent
boot should come before the port rewrites a timeline.
