-- brokkr verdict workload derived from examples/alloc/gc_churn.lua (see
-- that file for the probe rationale: sustained live heap + per-iteration
-- garbage, so collections have real marking work). Same kernel, repeated
-- K times per _bench call so one call is ~100ms and the standalone run
-- takes a few seconds in a release build.
