The claim is directly supported by the odaily.news source citing IRGC spokesperson Sadar Hussein Muhabi on May 4, 2026, confirming that Strait of Hormuz management procedures are unchanged and compliant civilian and commercial ships are safe. The X post by DeItaone corroborates this with the enforcement dimension. The Al Jazeera article confirms the IRGC published designated safe routes and a formal transit protocol in April 2026. The Wikipedia article establishes that a shipping safety protocol was agreed on March 4, 2026 after a 47-day blockade, making the IRGC May 4 reaffirmation of unchanged rules consistent with the post-crisis enforcement regime. Minor uncertainty remains due to broader context of ongoing tensions and selective enforcement documented in other sources.
