+-- Aggregated multinode disagg runs can produce a config with no decode
+-- workers for low-conc sweeps (e.g. conc=1 on dsv4 run 25296668638 had
+-- decode_tp=0, decode_ep=0, num_decode_gpu=0 with all 8 GPUs on prefill).
+-- The original `>= 1` checks rejected these rows during ingestion, so the
+-- conc=1 point silently disappeared from the official chart. Drop the
+-- prefill-side mirrors too for symmetry.
