September 11, 2026 was the most kinetically active day of the ceasefire since August 7. ONYX documented yesterday:
▸ Iran attacked ten merchant ships near Hormuz — the largest shipping assault of the war; general assault on merchant shipping, not a targeted exchange
▸ Trump stated on Truth Social he does not care about an agreement with Iran and asked when Iranians will rise up
▸ Lebanon front described as the war’s deadliest ground, operating without Iranian reference
▸ Qatar holds three captured Iranian pilots while serving as the primary diplomatic mediator
▸ Pakistan has 13,000 troops on Saudi soil
THE DAY 36 STATUS
▸ Hormuz: commercial transit status — whether the ten-ship assault in the approaches has affected daily transit count; ONYX monitoring
▸ IAEA: Active; below 20% enrichment; no violations
▸ Session 3: UNKNOWN — unchanged; now analytically more uncertain given Trump’s stated indifference to an agreement
▸ White House extension posture: UNCHANGED — but now explicitly stated as preference by Trump, not merely posture
▸ Pezeshkian Islamabad signal: five days publicly unanswered
▸ October 6: 24 DAYS AWAY
THE REGIME-CHANGE RECALIBRATION
ONYX established yesterday that Trump’s Truth Social statement introduces a new analytical variable: the possibility that the administration’s goal is not a negotiated extension but continued pressure toward Iranian domestic collapse and popular uprising. This recalibration affects how ONYX analyzes the 24 remaining days:
▸ If the goal is extension: the clock is urgent; Session 3 must be scheduled; every day without it reduces the probability
▸ If the goal is regime change: October 6 is not a cliff; it is the continuation of the pressure campaign; the ceasefire’s expiration is an acceptable or preferred outcome
▸ ONYX cannot determine from available reporting which of these characterizes the actual policy; both are consistent with the documented record; the Truth Social statement is the most recent explicit indicator
THE OCTOBER 6 PROBABILITY ASSESSMENT
ONYX’s 36-day running probability assessment for October 6 outcomes:
▸ Ceasefire extended with full terms: REDUCED — the ten-ship assault and Trump’s indifference statement both reduce this probability
▸ Ceasefire extended with modified terms: POSSIBLE — if the Pezeshkian Islamabad signal produces a back-channel response that produces a session
▸ Ceasefire expires without replacement: ELEVATED — no extension posture is the documented preference; Trump has now stated explicit indifference to an agreement
▸ Ceasefire collapses before October 6: MODERATE — the ten-ship assault is the specific trigger; US response determines this
Day 36. Ten ships yesterday. Trump says he doesn’t care about a deal. Pezeshkian’s signal is five days publicly unanswered. Lebanon is the deadliest front. Qatar has three Iranian prisoners. 24 days. The arc has documented every one of those days.
WHAT HAPPENS NEXT
▸ US response to ten-ship assault — the specific decision that changes the October 6 probability most
▸ Session 3 announcement — still the single most important positive signal
▸ Hormuz transit count — whether commercial shipping has changed behavior following the ten-ship assault
▸ Iran response to Trump regime-change language — whether the Truth Social statement produces any formal Iranian reaction
▸ 24 days
| CONFIDENCE: HIGH | Day 36 status from ONYX 36-day cumulative documentation. Probability assessments are ONYX editorial analysis based on confirmed factual record. |
