Turn clickstream events into user sessions
Repair session-audit.sql against web_events. Return user_id, session_number, session_start, session_end, and event_count, with one row per session. A gap exceeding 30 minutes starts a new session; exactly 30 minutes does not. event_time is UTC epoch seconds, with event_id breaking ties. Number sessions from 1 independently per user, retain every event, and order results by user_id then session_number.

LabKeep the nightly transform on local time
Repair pipeline-schedule.yaml so one enabled orders-nightly-local schedule starts the job daily at 02:15 Australia/Sydney without delivery drift. Retry failed starts twice for up to 3600 seconds before ScheduleDLQ receives them. Preserve that queue and limit execution-role access to Scheduler, the supplied Glue job, and the queue.
