Slight rebalancing. B (negotiated ceasefire) ticks up for the first time since the Islamabad collapse - talks haven't died, Lebanon ceasefire shows Trump can extract concessions from allies, Iran studying proposals rather than rejecting outright. C dips to offset. The Isfahan chain thesis holds but Monday is a genuine fork: if talks produce a framework and the ceasefire extends, B rises substantially and C drops. If talks fail and the ceasefire expires, H activates and the chain resumes.

The Isfahan Chain reshapes the scenario landscape. Scenarios A (exit) and C (ground ops) are converging: the Isfahan raid IS the exit. The blockade is the forcing function that removes Iran's Hormuz leverage, leaving nuclear escalation as Iran's only remaining card - which is exactly what legitimizes the operation the force was positioned for. Scenario B collapsed after Islamabad talks failed. The ceasefire is collapsing in real time. Trajectory confidence rises to 0.50 - the blockade clarifies the endgame even if it doesn't resolve it. First session using prediction chains and board state check.

The ceasefire reshuffles everything. Scenario B (negotiated ceasefire) rises to lead position for the first time - the framework exists and talks are scheduled. But the ceasefire admits three readings we cannot yet distinguish: (1) genuine exit ramp, (2) stall for force buildup - ceasefire window perfectly matches carrier/MEU arrival timelines, (3) Israeli sabotage target - Netanyahu already carving exceptions. The Islamabad talks on Apr 10 are the first data point. Our trajectory confidence is the lowest in the project's history (0.30) because we've moved from a pattern-dominated phase (where we're strong) to a decision-dominated phase (where we suck).

The alliance contradiction is now the war's central analytical problem. Israel is openly sabotaging US diplomacy (5 for 5 pattern). Ground op type determines endgame: Isfahan raid → Scenario A exit; Kharg/Strait → grinding commitment. Gulf interceptor depletion (Bahrain 87%) creates a structural time limit on the current equilibrium. China and UK-led coalitions entering the picture signal that the post-war order will not be American-directed.

Scenario G (infrastructure war spiral) holds at 5% - Trump has backed down three times but the threat isn't withdrawn, and Israel is hitting grid/industrial targets independently. The dominant dynamic is the conditioning-capability gap: the ground phase is being publicly sold on a timeline the logistics don't support. Mid-April is the earliest convergence window. The race between conditioning and diplomacy is the new central tension.

Scenario B (negotiated ceasefire) rises to 20% - first structured proposal exchange. Scenario D (wider war) rises to 10% - Houthi entry, Russia active support, Pakistan-Afghanistan conflict. Scenario A (US withdrawal) drops to 35% - Israeli acceleration complicates exit. The war now has a genuine diplomatic track AND a military sabotage track running simultaneously. Which one wins - the R003 question - determines everything.

Reframe, not shift: The old "Grinding attrition" scenario now explicitly includes targeted ground operations as the most likely escalation within that path. No probability mass moved - the scenarios still sum to 100%. The force convergence compresses timelines: 7,000+ troops in theater create a use-it-or-lose-it dynamic. Either the administration authorizes operations, or the forces become a very expensive deterrent that eventually goes home.

"Infrastructure war spiral" (G) drops from 25% to 10% on the TACO outcome and Gulf vulnerability constraint. That probability mass moves to "US-imposed halt" (A, up to 40%) and "Negotiated ceasefire" (B, up to 15%). The war is trending toward ending, not escalating - but the ending leaves every strategic problem unresolved. Hormuz stays closed for months. Isfahan uranium survives. Iran's nuclear motivation is strengthened. Israel is stuck in Lebanon. The "victory" will be declared, not achieved.

"Regional expansion" (D) dropped from 20% to 5% on the Houthi reassessment. That probability mass moved into the new "Infrastructure war spiral" (G) scenario at 25%, reflecting the power plant ultimatum and the tit-for-tat pattern. The war is less likely to spread geographically but more likely to intensify within the current theater.

Taxonomy change: Scenario F (Protracted conflict) was absorbed into a redefined Scenario C (now "Grinding attrition" rather than "Ground war"). The probability mass didn’t disappear - C’s jump from 6% to 25% reflects F’s 35% being merged in and reweighted alongside the original C. Scenario A surges to 35% as the dominant outcome for the first time, driven by Trump’s exit rhetoric and Iran’s declining conventional capability.

Protracted conflict ticks back to 35% as the gap between Trump's withdrawal rhetoric and operational reality widens - you cannot wind down a war while requesting $200B and deploying amphibious groups. 'Mission Accomplished' drops to 18% because Iran's willingness to hit Haifa demonstrates they will not quietly absorb strikes and let Trump claim a clean win. Negotiated ceasefire rises modestly on the KH pause and Nowruz/Eid diplomatic window.

The energy war going mutual is the dominant shift. Israel's unilateral South Pars strike and Iran's Ras Laffan retaliation fundamentally changed the conflict's character. Regional war surges 5 points because the war now directly damages third-party states. 'Mission Accomplished' drops as the energy escalation denies Washington a clean off-ramp. Protracted conflict dips because the energy tit-for-tat increases probability of a decisive break rather than indefinite stalemate.

Divergence between military and strategic outcomes: Iran is being physically dismantled (missiles down 90%, navy gone) yet Hormuz is still closed, oil above $100, and US casualties accumulating. Regional war ticks up on the Bahrain airport strike and Turkey NATO incident. Regime collapse dips as Mojtaba's succession and public address suggest the system is holding under pressure.

Mojtaba's consolidation simultaneously stabilizes Iran (reducing E) while giving the US an off-ramp narrative - Khamenei is dead, the successor is a 'lightweight,' declare mission accomplished. The $119 oil spike and 6,668 civilian units targeted create real pressure on Washington to wind down. Confirmed Houthi non-entry continues to deflate regional war probability.

The dominant shift is toward protracted conflict and early US withdrawal as the two most likely outcomes. Iran's missile expenditure rate indicates stockpile conservation, the Houthis failed to open a military front, and Israel committed ground forces to Lebanon rather than Iran. The wider regional war scenario loses probability because the actors who would have widened it - Houthis, Gulf states - are staying out.
