4. What Decides Next

• **[NEW] Falsification test — passage:** The clearest falsifier of the closure regime is a sustained return of commercial tanker passage above the reported 4 tanker transits, whether under the proposed deal or outside Iranian arrangements ^[3][4][5]
• **[NEW] Escalation test — physical damage:** Another disabled tanker or Persian Gulf fire would strengthen the physical-disruption case, while an Iranian response to an Israeli threat would broaden it into direct confrontation ^{[10][2][6][7]}
• **[ONGOING] Resolution test — sequencing:** The key sequence is whether Tehran and Washington accept the proposed five-day give-and-take, which side moves first, and whether an early nuclear concession remains part of the bargain despite the reported exclusion of nuclear issues from the four-country talks ^[13][4]
• **[ONGOING] Market test:** A sustained Brent fall below $112 per barrel and normalization of WTI call skews from +7.2% would be consistent with the immediate supply-risk premium unwinding ^[8][9]
• **[NEW] Catalyst clock:** Another U.S. “Epic Fury,” an Israeli threat followed by Iran’s warning of a reciprocal response, and the October 27 Israeli election could compress the mediation window ^[1][10][22]
