An as-known-at-10:30 review would instead have FP2's uncorrected 10:05 confirmation because the correction was not logged until 11:00. FP2's original schedule alone would not establish execution. Keep effective event time, record availability and correction history separate; the later aggregate confirms only the final counts, not every earlier timestamp.",
