Iran's Supreme National Security Council formally ratified the ceasefire on 7 April. This is the institutional anchor event — the body that would have to re-authorize any resumption of hostilities on the Iranian side has put its name to the pause.

Iran SNSC Formally Accepts 2-Week Ceasefire
Iran's Supreme National Security Council ratified a 2-week halt Apr 8 with embedded conditions (Hormuz under Iranian AF, sanctions relief, US base withdrawal) Trump has not publicly agreed to.

What Happened
SNSC ratification = Iran formalizing the pause at the highest deliberative level.
Most of the substantive content is already in the knowledge base (Khamenei backstory event); SNSC ratification adds procedural durability but no new facts. Marginal tree move: Branch C (Op Delayed) +1; Diplomatic +1; BIF-1 resumption -1.
Watch for any SNSC-level reversal during the 15-day window. Institutional reversals require a triggering incident — if one occurs, the ceasefire collapses inside days, not weeks.

Iran SNSC formally ratifies ceasefire; issues 'hands on trigger' statement

Islamabad talks scheduled to begin with divergent texts
Words vs Actions
Words
- Trump: 'Almost all points of past contention have been agreed to.'
- Iran SNSC: formal acceptance of 2-week ceasefire
Actions
- Iran SNSC statement: 'this does not signify the termination of the war … Our hands remain upon the trigger.'
- Iran's acceptance conditions (Hormuz under Iranian AF, sanctions relief, US base withdrawal) are not publicly endorsed by Trump
- Two divergent texts going into Islamabad Apr 10
Both sides formally agreed to a ceasefire on day one with mutually incompatible operative terms. Iran's own statement negates the framing of peace. The 'acceptance' is a procedural pause, not a convergence of positions — the divergence is baked into the founding documents.
Model Impact
BIF-1 Ground Op + Branch C (Op Delayed)
This is the anchor event for Signal-004. Most of the information was already absorbed via the khamenei-backstory and spectre-15day-reload events; the marginal value here is the formal SNSC ratification itself (observable institutional commitment) and the on-record Iranian 'hands upon trigger' statement that negates the peace framing from day one.
The net effect is a modest extension of the pause (Branch C +1) and a small rise in the diplomatic endgame (+1), offset by the divergent texts that pre-load Islamabad breakdown. Tree position remains in the 'institutional time-purchase' state rather than a genuine de-escalation.
