File the week as the cycle it was, because the shape is the story. Night one and two: strikes - roughly 170 targets across Iran's coasts, ports, air defenses, and logistics. Nights three and four: a pause, held deliberately, described by officials as strike-then-pause to let diplomacy work. Then the squeeze: Tuesday the US revoked the waiver that let Iran sell oil; Friday, Treasury sanctioned a Dubai-based financier, Ali Ansari, and his exchange houses, accused of channeling wealth to the new Supreme Leader Mojtaba Khamenei and the IRGC [3]. Strike, pause, squeeze - the classic escalation ladder, run in one week.

Friday evening brought the move after-action reports wait for: the climbdown, relayed secondhand but in detail. US officials say Iran's leadership privately told Trump advisers the attacks on Hormuz shipping - the acts that restarted this war - were a 'mistake,' committed by 'errant' hardliners trying to undermine the diplomacy; Bloomberg's sources render it 'rogue elements' of the IRGC [1][2][3]. Attribute it properly: this is Washington describing Tehran's private message, one side of a wire. If accurate, it is the most important sentence of the week - a government disowning its own escalation to keep a negotiation alive.

Which brings the file to today, and to a meeting whose terms were briefed in public before the delegations landed. Iran's foreign minister Abbas Araghchi flies to Muscat leading the Hormuz delegation [5]. The US pass-fail line, per senior officials Friday: Iran must declare 'all channels of the Strait of Hormuz are open and they're not shooting at ships anymore' - open 'in the same way it was before the conflict.' The or-else was briefed with equal clarity: 'if it's not their position, then it's not going to be a great day for them' [1]; failure 'would result in consequences' [2].

The water gives the honest readout of where things stand. The Navy's guidance says the strait's southern route 'remains available for all traffic' [3]. Available is not used: three fuel tankers were broadcasting positions in the strait Thursday - two of them under US sanctions for hauling Iranian oil - against the 120-plus ships a day that ran before the war [3]. Insurance, not ordnance, closes a strait; the premium does not care whose fault the last missile was. Oil closed Friday at 76.01 for Brent, easing on hopes for today, still up 5.5 percent on the week [4] - the tax the cycle already collected from everyone who drives.

The after-action summary, then, for a meeting that starts within hours. The escalation cycle ran its full course in seven days and produced, by Washington's own account, a private Iranian disavowal and a public American ultimatum. Both capitals have now bet on the same sentence being said out loud in Oman. If it is said, the week's arc becomes a case study in coercive de-escalation, and the tankers switch their transponders back on. If it is not, the promised word is 'consequences,' and this file gets a second volume. Either way, the record shows exactly how seven days took a fifth of the world's oil hostage to one declaration - and who, on each side, wanted it that way.
