Sealed corridor replay · Bab el‑Mandeb
Pipeline structural stress on Bab el-Mandeb four months before the Red Sea peak.
The corridor replay scored Body 4.57/5 and Perceived Insecurity 4.68/5 by September 2023 — four months before the January 2024 Houthi missile‑attack escalation. Freight rates and incident feeds were still lagging the domain stress the engine recorded on the chokepoint.

Scored at 2023-09 — four months before the January 2024 Houthi missile‑attack escalation. Pipeline‑only (acute pulse shadow = 0 at this cutoff).
What happened
- •Houthi rebels escalated attacks on commercial vessels transiting the Red Sea / Bab el‑Mandeb corridor starting in late 2023, with the Galaxy Leader seizure on 19 November 2023 as the initial high‑profile event and the US‑led Operation Prosperity Guardian announced 18 December 2023.
- •January 2024 marked the peak disruption: major shipping carriers rerouted around the Cape of Good Hope, insurance premiums spiked, and the corridor experienced its most severe throughput reduction.
- •Conventional incident feeds and freight‑rate dashboards confirmed the disruption after it was fully underway — not before the structural stress had built.
What the Index showed
- •By September 2023, four months before the January 2024 peak, the Bab el‑Mandeb corridor replay scored Body 4.57/5 (91/100), Perceived Insecurity 4.68/5 (94/100), and Courage 0.72/5 (14/100) — NII 4.44/5 (89/100, Severe).
- •The structural stress was measurable before the headline escalation: pipeline FRED indicators and global baseline scores had already captured the pre‑conditions while freight and incident feeds showed calm.
- •The acute evidence‑pulse activated at the January 2024 event window (shadow 62, Elevated) — confirming the pre‑existing structural stress rather than discovering it late.
- •Same sealed corridor‑profiles pipeline the live Index runs today. Bab el‑Mandeb remains a priority corridor on the live scanner.
Methodology & evidence
- •Engine: V5‑locked corridor‑profiles pipeline with corridor domain premiums (Body +0.95, Perceived +0.35, Courage +0.10) applied to global baseline FRED indicators at the September 2023 cutoff.
- •PIT discipline: no acute evidence‑pulse at the Sep 2023 cutoff (pulse not yet confident at that date). Pipeline scores are the honest PIT‑verified signal.
- •The live corridor page at /corridor/bab‑el‑mandeb carries the ongoing scanner score with the full pulse overlay — this sealed replay is the structural version.
- •No FAO, WEO, or conflict‑forecast series in the corridor ledger. This is chokepoint thermodynamics, not event prediction.
Sealed replay does not claim
- •We do not claim the corridor engine predicted the specific Houthi missile attack date or target.
- •We do not claim dual Watch/Act clocks on the corridor (this is a corridor replay, not a sovereign‑level episode gate).
- •We do not claim the acute pulse was active at the Sep 2023 cutoff — it was not (shadow 0 at that date).
- •We do not claim freight rates or insurance premiums moved before the October–November 2023 rerouting announcements.
Diligence
- PASSSealed V5‑locked corridor‑profiles pipeline — Same corridor‑profiles engine as the live Index. Premiums frozen — no post‑event retuning.
- PASSPoint‑in‑time cutoff — FRED indicator observations up to Sep 2023 — no future information in the score month.
- PASSOutcome validator only — Jan 2024 event anchor never scored in the engine. Acute pulse (shadow 62 Elevated) confirms pre‑existing stress.
- PASSCorridor diagnostic — not a client‑lock gate — Corridor replay proof, not a sovereign‑level Watch/Act dual‑clock gate.
