Operational Layer-1 corroboration of the 260412 blockade announcement: USS Lincoln CSG redeploys, Eisenhower CSG on station, amphibious groups positioned. The interdiction dome is physically forming — this is no longer announcement, it is posture.

US Begins Hormuz Blockade; Lincoln CSG Redeploys
Destroyers and littoral combat ships operate in Gulf of Oman; Lincoln CSG redeployed to provide air cover; formation consistent with amphibious precursor, not standard interdiction.

What Happened
From statement to operational reality in under 48 hours. The blockade is running.
Multiple verified Layer-1 elements stack: carrier redeploy patterns, amphibious positioning, sortie tempo. Six claims verified against MarineTraffic, OSINT overlays, and deployment notices. The Words-vs-Actions gap between Vance's 'goals achieved' and this posture is the single largest rhetoric-reality divergence of the batch.
Reinforces BIF-1 gate shift. The physical predicate is not speculative — it is observable in daily OSINT. Amphibious positioning keeps Branch B (Bloody Landing) dominant at 60% conditional.

Words vs Actions
Words
- Blockade framed as interdiction of 'extortion' — legal jurisdictional cover
- Trump calls enforcement 'checking ships'
Actions
- CSG pressed against coast — CAS posture, not standard interdiction
- Iran repairs launcher infrastructure in parallel (sat imagery)
- China pre-positions refusal to comply
The naval formation is not a maritime police action — it is force generation for close air support at Bandar Abbas / Qeshm. Historic parallels: Korea, Vietnam, Desert Storm, OIF 2003. The blockade frame provides international-law cover while the hardware prepares for beach crossing.
Model Impact
Layer-1 corroboration of Trump blockade announcement
The dome formation hugging Bandar Abbas and Qeshm Island is historically-specific naval signaling. CSG commanders do not press against hostile coast for interdiction — they press against hostile coast for close air support of ground formations. The posture is inconsistent with 'blockade and see what happens' and consistent with BIF-1 Branch B preparation.
Parallel Iranian infrastructure repair (CNN sat imagery 260416) shows Iran is not treating the ceasefire as a deal — it is treating the pause the same way the US is: as reload time.
