"""An audit row keeps the request that made it

Revision ID: 0111_audit_request_id
Revises: 0110_intervals_in_sysconfig
Create Date: 2026-10-18

The activity page opens an admin action's log lines from its row: `audit_log.request_id` is the
request the change was made in, the same id `log_events.request_id` carries. Older rows have none —
the request that made them was never recorded.
