Curated 2026\-10\-12 \(TC\-1059\)\. NOTHING IS TAKEN\. The authors' archive \(Zenodo 10\.5281/zenodo\.15432565, their ref\. \[41\]; attached to the paper in the library\) holds the Fig\. 4 populations against time, RMTpopulations\.csv, at eight NIR intensities \(0\.8 to 2\.5e14 W/cm2, more than the paper shows\), to t = 2999\.81 au\: the ground state, the selected 1P^o bound states and the population beyond 20 au\. They would give a many\-electron xenon in a stated pulse, but the pulse is not the paper's\. THE CARRIER \(tools/extract/hutcheson\_2025\.py, which fails otherwise\)\. The paper's NIR is '760 nm' \(p\. 1\)\. The populations oscillate at twice the carrier frequency \(p\. 2\); the spectrum of d\(ground\)/dt over 400 to 1400 au peaks at 2 omega with omega = 0\.0675 to 0\.0683 au at every intensity, i\.e\. 667 to 675 nm, not 0\.05995 au \(760 nm\)\. The archive's own bin/plot\_rmt\_populations\.py draws Fig\. 4 with pulse\(0\.8, IR\_freq=0\.06798\), i\.e\. 0\.06798 au \(670 nm\); helper\_functions\.pulse's other defaults are a field envelope exp\(\-\(t/186 au\)^2\) and E0 = 0\.05336 sqrt\(I / 1e14 W/cm2\) au\. So these NIR\-only runs were most likely made with omega = 0\.06798 au, as the 2022 archive's example generator \(hartmann\_2022's notes\), and not with the 0\.06 au of hartmann\_2022's runs\. They also deplete the ground state less at the same label \(0\.883 against hartmann\_2022's 0\.812 at 1\.1e14; 0\.797 against 0\.623 at 1\.5e14\), as a different pulse would\. The pulse is to be confirmed with the authors before any value is used; then the populations at the end of the run would be the data\. THE MEASURE, if taken\: the population beyond 20 au includes Rydberg states \(the authors' warning\) and falls after the pulse \(0\.0754 at \+20 fs, 0\.0703 at the end, 0\.8e14\); the ground\-state survival is the cleaner measure, as in hartmann\_2022\. **Recorded bibliographic identity status:** VALIDATED.
