+# Scheduled curated-config pass (not a full sweep) so every
+# /overview model×hardware cell gets a same-batch data point at least weekly
+# (#2304). The config-keys list is the scope knob: pilot is dsv4+qwen3.5 on
+# b200/b300; extend to mi355x then gb200/gb300 once the pilot proves the
+# ingest path. `schedule` events get no event bump in ci-priority.yaml, so
+# PR and main-push sweeps always preempt these jobs.
