"""Regression test for reconnect-reconciliation inflating Total Print Time (#2592).

On a farm, a connected-edge reconcile closes out every stale ``status="printing"``
archive as an aborted run whose duration was computed ``completed_at - started_at``
— i.e. the whole multi-day disconnect gap — and the Stats endpoint's fallback
recomputed the same value even when the stored duration was 0/NULL. A single
reconnect could add hundreds of fictitious print hours (reporter @Jostxxl saw
Total Print Time jump from ~1,500h to 3,215h).

The fix stores an explicit 0 for reconciled entries and makes the Stats total
trust that 0 instead of recomputing from the stale timestamps. This test drives
the ``/archives/stats`` endpoint with hand-crafted rows covering the reporter's
scenarios.
