# Relay lifecycle events

Thirty-one ordered sample events for reconstructing batch state and joining station details.

Waypoint Reference · Version 2026.10.3

All network records are synthetic examples.

## Fields

- id (string): Stable event identifier; unique across this dataset.
- batch_id (string): Foreign key to the batch that owns this event.
- waypoint_id (string): Source station for queued/dispatched events; destination for delivered events.
- event (string): One of queued, dispatched, or delivered.
- timestamp (string): Fixed ISO 8601 UTC timestamp; increasing within each batch.
- sequence (integer): Contiguous ordering within one batch, starting at 1; never a global event offset.
- units (integer): The owning batch's units, repeated for event context; do not sum across all lifecycle stages.
- synthetic (boolean): Always true: this is a deterministic example event.
