{“what”:“Unique numeric identifier for the event; auto-generated sequence.”,“why”:“Without it, events cannot be uniquely identified or referenced.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.228591064+00:00”}

{“what”:“Identifier of the assignment this event belongs to.”,“why”:“Without it, it is unknown which assignment the event refers to, making the log useless.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.250393896+00:00”}

{“what”:“Status value the assignment was in before the transition; null when no prior status.”,“why”:“Without it, the starting point of the transition is unknown, so the change cannot be reconstructed.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.269128990+00:00”}

{“what”:“Status value the assignment moved to; null if no new status was set.”,“why”:“Without it, the outcome of the transition is unknown, so the final state cannot be determined.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.297198035+00:00”}

{“what”:“Free-form text with extra context about the event, such as reason or message.”,“why”:“Without it, context beyond status change is lost, making debugging and auditing incomplete.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.327447333+00:00”}

{“what”:“Error message if the transition failed; null on success.”,“why”:“Without it, failed transitions are indistinguishable from successful ones, hiding problems.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.445040845+00:00”}

{“what”:“Timestamp with time zone of when the event was logged.”,“why”:“Without it, the order and timing of events is unknown, breaking chronological analysis.”,“by”:“fleet-annotator-worker”,“at”:“2026-09-22T23:54:10.500236624+00:00”}
