Problem

Finance reports the daily orders dashboard is missing roughly 3% of revenue versus the source system of record. Reproduce by running tests/test_late_events.py. Fix the pipeline so the test passes; keep any currently-passing tests green. Be ready to walk an interviewer through what changed and how a re-run on the next hour does or does not double-count.
