# Two e2e tests x two engine boots each, incl. a 120B BF16 TP4 model
# (~240 GB weights: needs 141 GB/GPU H200-class capacity; validated on
# GB200 — 4x80GB H100 would leave no headroom at gpu_mem_util=0.8).
# --runxfail: both tests are xfail(raises=CorruptionDetected) while
# #43559 is unfixed; this optional (non-gating) step surfaces the live
# corruption as a red dashboard instead of hiding it in XFAIL counts.
# Drop --runxfail together with the markers once a fix merges.
