Major General Ahmad Vahidi and his hardline IRGC faction have taken operational control of Iran's military posture and negotiating delegation, GlobalSecurity.org reported on 22 April, sidelining civilian moderates including Foreign Minister Abbas Araghchi 1. The 17-18 April Hormuz open-then-close sequence, when the Foreign Ministry announced a reopening and the corps reversed it inside hours, set the pattern. The 22 April boardings confirmed it.
Vahidi rejected negotiations on Day 53 , telling IRGC deputies the corps opposes any settlement while the US blockade stands. Baqaei declared on 19 April that Iran's enriched uranium was non-transferable ; on Day 54 the corps translated that rhetorical line into boarding parties executed under the four-condition Tabnak order .
The split runs on institutional rails. The Majlis's 221-0 vote on 11 April to suspend IAEA cooperation, delivered through Speaker Mohammad Bagher Ghalibaf's bloc, gave the corps legal cover for what it now executes on the water. Any Araghchi signature at Islamabad, Oslo or Vienna is a starting offer the corps will choose whether to honour.
