… calculation (#68647) DeadlineReference.AVERAGE_RUNTIME computes a deadline from the average duration of past DAG runs, but the query filtered only on dag_id + start/end-date present — with no DagRun.state filter. Failed runs (which may have died fast or hung before failing) were folded into the average, skewing the computed deadline: a fast-failing history makes it too short (spurious misses), a slow-then-failed history makes it too long (real slowness never trips it). Filter the duration query to successful runs only. Add tests asserting failed runs are excluded from the average and that the deadline is skipped when too few successful runs exist. --------- (cherry picked from commit 88e6110) Co-authored-by: Sean Ghaeli <58916776+seanghaeli@users.noreply.github.com> Co-authored-by: Sean Ghaeli <ghaeli@amazon.com> Co-authored-by: Ramit Kataria <ramitkat@amazon.com>

DeadlineReference.AVERAGE_RUNTIME computes a deadline from the average duration of
past DAG runs, but the query filtered only on dag_id + start/end-date present — with
no DagRun.state filter. Failed runs (which may have died fast or hung before failing)
were folded into the average, skewing the computed deadline: a fast-failing history
makes it too short (spurious misses), a slow-then-failed history makes it too long
(real slowness never trips it).
Filter the duration query to successful runs only. Add tests asserting failed runs
are excluded from the average and that the deadline is skipped when too few
successful runs exist.
