Audit log entries record state changes and actions on schedules, versions, and series. Every significant lifecycle event is captured with before/after state snapshots and request context.

Event types

Event type	Trigger
`schedule.created`	A new schedule is created via `POST /schedules`
`version.submitted`	A schedule version is sent to the TSO
`version.accepted`	TSO ACK or CNF confirms acceptance
`version.rejected`	TSO rejects the submission
`version.status_changed`	Any status transition on a version
`series.status_changed`	Per-series status update from a partial CNF
`anomaly.received`	An ANO message is received from the TSO
`status_request.sent`	A manual status request is triggered

Data structure

The data field is a combined object containing:

before — state snapshot before the event (when applicable)
after — state snapshot after the event
metadata — additional context (e.g. TSO response codes)
request_id — correlation ID for the triggering API request

Timestamp precision

The created_ts field includes millisecond precision (YYYY-MM-DDTHH:mm:ss.sssZ) to allow precise ordering of events that occur in rapid succession.
