What would prove it wrong
This reading is retired if EUR/PLN moves by more than 0.5% in the same direction and session as a future large WIG-BANKI swing around the NBP's next projection round; it is sustained if EUR/PLN continues to trade within 0.5% daily moves through further bank-index volatility.
Review condition
the NBP's next projection round: a EUR/PLN move of more than 0.5% in the days around its publication, in step with any WIG-BANKI swing

How it settled
The referee is correct: the WIG-BANKI 2.41% move was recorded at the 7 October close while the EUR/PLN 0.28% figure comes from 8 October intraday, so no same-session pairing was actually tested, and the NBP projection-round trigger has not yet occurred, meaning the falsifier's precise condition remains untested rather than satisfied.
