What Happened

Within 24 hours of the 7 April ceasefire, the IDF struck approximately 100 Hezbollah sites across Lebanon — a rearmament-interdiction campaign beginning the moment the main front paused. The ceasefire fractured on its first day.

~100-site Lebanon strike within 24h of the ceasefire = ceasefire broken before it set.

This is the highest-scoring single event of the week (37/40 RED). BIF-1 resumption probability moves back up (72→73%); Branch B durability strengthens (56→57%); Endgame Diplomatic compresses (7→6%).

The Lebanon strikes reveal that Israel is using the pause to run a parallel campaign against Hezbollah's reconstitution. This is exactly the scenario that most cleanly reopens the main Iran front after 22 April.

Words vs Actions
Words
  • Trump: 2-week ceasefire announced 2026-04-07
  • Iran 10-point plan: permanent end to Israeli strikes on Hezbollah
  • Pakistani, French, Egyptian mediators: Lebanon is inside ceasefire envelope
Actions
  • ~100-site IDF strike wave on Apr 8 — largest single-day action of the war
  • Central Beirut hit without warning
  • Netanyahu public declaration carving Lebanon out of ceasefire
The ceasefire did not survive 24 hours on the Lebanon axis. Netanyahu's Apr 4 warning to Trump was pre-commitment, not bluff. This is the dominant near-term collapse signal in Signal-004 — higher weight than the ceasefire announcement itself because observable action directly and maximally contradicts the diplomatic framing.
Model Impact
BIF-1 — Lebanon-Axis Collapse Signal
This is the single most operationally significant event in Signal-004. The ceasefire literally did not survive 24 hours on the Lebanon axis. Netanyahu's Apr 4 warning was pre-commitment, not bluff. The ~100-site strike wave executed in 10 minutes is the largest single IDF action of the war and is incompatible with any reading of a genuine de-escalation.
Scenario weights for the 15-day clock (expiry ~Apr 22): (a) Iran treats Lebanon strikes as breach and resumes before Day 15 — P≈0.35; (b) Iran tolerates strikes to bank structural wins, Hezbollah absorbs, Axis of Resistance fractures — P≈0.40; (c) Third-party escalation via Houthis or Iraqi proxies while formal US-Iran track holds — P≈0.25. Tree effect: BIF-1 +1, Branch B +1, Branch C -1, Diplomatic -1.
