The other half of the pair. Same JWST programme, same MIRI channel, second observation, one sub-band longer — jw02926-o002 where Episode 8 was o001. If the series has a controlled comparison in it, this is that comparison.
The build is identical: fourteen minutes of the hundred most distinctive passages, ninety-three minutes of the open field running brightness, obstruction, gradient and into lines, seven minutes of the fifty rarest.
What changed with the sub-band: brightness still leads the distinctive suite, but flow and anisotropy have climbed to join it, and the line reading has almost vanished from the rare suite — one passage out of fifty, against nine in the short-band cube. The rare material here is spread across all seven readings rather than concentrated.
The same sky, moved slightly along in wavelength, does not sound like the same data.
Before Birth is an acknowledged test series.
