Significance

The Kohourestan Bridge strike is the first infrastructure (not military) target inside Iran in this renewed phase. It cuts the main road link between Iran's largest port (Bandar Abbas) and the Fars hinterland — economic damage signal. IRGC's reported direction to Houthis to close Bab el-Mandeb is the formal move to multi-chokepoint denial. The dark-tanker count more than tripling (23.2 baseline → 78) is the empirical proof of the TechTimes "AIS failure" analysis materializing. With 6 P&I clubs withdrawn and 8× war-risk insurance, the cost of doing business in Hormuz is becoming prohibitive.
