}

Alert generated when impossible travel is detected.

Contains full context about the suspicious travel pattern including source/destination locations, timing, and confidence metrics.

Fields

user_id: String

User ID that triggered the alert.

severity: Severity

Severity based on how impossible the travel is.

from_location: GeoLocation

Location of the previous login.

from_time: u64

Timestamp of the previous login (Unix ms).

to_location: GeoLocation

Location of the current login.

to_time: u64

Timestamp of the current login (Unix ms).

distance_km: f64

Great-circle distance between locations in kilometers.

time_diff_hours: f64

Time difference in hours.

required_speed_kmh: f64

Speed required to make the trip (km/h), -1.0 for instant.

confidence: f64

Confidence score (0.0 to 1.0) based on accuracy and context.
