Event Feed
Five-signal composite scoring (news · fire · flights · maritime · markets) yielding per-country L1–L5 event levels.
What It Does
The Event Feed is the most synthesised view in NeoLexx. It combines five independent signals — news velocity, fire anomalies, flight route movement, maritime port-call activity, and equity movements — into a single composite score per country. Countries are then graded L1 (nominal) through L5 (critical) based on that score.
It is the best starting point when you want a quick answer to "where is the most unusual activity right now across all signals?"
Data Source
The Event-Engine background worker runs approximately every 10 minutes and pulls the latest scores from five persisted data streams:
- News velocity z-scores from the News-Chef pipeline
- Fire anomaly z-scores from the Fire-Watcher pipeline
- Flight inbound/outbound route anomaly from the Flight-Radar airport snapshot spine
- Maritime port-call anomaly from the Maritime-Watcher port snapshot spine
- Equity movement % from the Market-Watcher
Results are stored in SQLite and served by the Event-Engine cache.
Scoring
The composite score uses fixed weights:
News, fire, flight, and maritime signals are mostly one-directional — higher than normal matters more. Equity is bidirectional — sharp drops matter as much as sharp rises.
L-level thresholds:
- L5 Critical: score ≥ 2.0
- L4 High: score ≥ 1.2
- L3 Guarded: score ≥ 0.7
- L2 Elevated: score ≥ 0.3
- L1 Nominal: score > 0
Reading the Map
Pulsing markers: Countries at L3 or above show pulsing circular markers at zoom ≥3. L5 markers pulse faster (1.2s cycle) and are larger (30px) than L3–L4 markers (1.8s cycle, 22px).

Signal context strip
Five horizontal bars show the current value and fill % for each signal component: article velocity, fire anomaly, flight route anomaly, maritime anomaly, and equity movement.
Narrative text
If available, a brief machine-generated summary of the driving signals.
Level-grouped signal cards
Cards grouped by level (L5 red → L1 gray), each in a horizontal carousel. Cards show: composite score, article velocity, fire anomaly, flight movement, maritime calls, and equity values.

Limits
- Composite scores are weighted averages — a country can reach L3 on news velocity alone with flat fire/market signals
- Equity signals are market proxies, not direct proof of a real-world event by themselves
- The 10-minute event engine cycle means scores intentionally move more slowly than raw headline or market refreshes
