Their census settles the population at 25 three-chunk regions, confirming my
count, and corrects their own claim twice: multichannel-specificity holds (17 of
17 changed are three-chunk), but 'all three-chunk regions were broken' is false --
8 of 25 were already fine.
Measured every three-chunk region's span myself: the 8 unaffected run 71680 ..
1400832 B, the 17 affected run 2023424 .. 6516736 B. The cap separates them
exactly with a 622592 B gap between the sets, so this confirms the MECHANISM --
a byte-size threshold -- not just the list of names.
My first run reported 17 contradictions: every span read 0 B because awk took the
trailing 'B' rather than the number. Uniform, consistent and entirely wrong, and
it would have looked strong because the failure fell along the line under test. A
broken extractor produces a pattern shaped by the question. What saved it was the
8 confirming rows reading 0 B too -- visible only by reading the half that agrees
as carefully as the half that does not.
