Daryani et al.'s year-naming test does not reach ChronoCulture's older-year asymmetry — it tested only naming the most recent surveyed year, which made no real difference, leaving that one ChronoCulture claim single-sourced

The corroboration that Daryani, Bogen & Daepp provide for the ChronoCulture branch stops short of one of its three claim-notes. ChronoCulture's year-naming finding is a conditional asymmetry across two target years decades apart: naming the year helps near-zero on average, but naming the older of the two years shows a growing benefit as the real shift between them grows large, while naming the newer year does not.

Daryani et al. tested a different, narrower question. They compared naming the country alone against naming the country together with its most recent surveyed year, and asked whether the explicit recent date pulled a model's answer closer to that recent snapshot. It did not: naming the country alone put models about as close to the recent snapshot as naming the country and year together, with a difference close to zero for every model, from −0.005 for Claude to +0.009 for GPT. In their words, naming the recent year neither refines a model's answer nor moves it toward the surveyed position for that year.

This is directionally consistent with ChronoCulture's finding that year-naming is weak on average. But because Daryani et al. never varied a decades-distant older year under a large real shift — the exact condition under which ChronoCulture's benefit appears — it can neither confirm nor disconfirm that specific conditional effect. That piece of the branch therefore remains single-sourced on arXiv:2610.20472 alone (independent_roots: 1), and the open verification is tracked at question-corroborate-chronoculture-older-year-naming-asymmetry.
