# The successor reveal-construction SCREEN: four arms, 256 paired games, depth
# 4 / seven strata, memo engine, shadow unchanged search on every non-frozen
# decision.  Opens the leased range 0xa52d0200+ exactly once.  Do not run this
# outside the frozen successor protocol; the coordinator launches it.
#
#   screen.sh <output-stem> <seed-lease-id>
#
# Writes <stem>.json (arms index) and <stem>.{frozen,A300,A900,B}.json
# (drop7-lifetime-cohort-v1), rewritten after every 4 completed games so an
# interrupted run leaves a partial, "complete": false artifact.  The runner
# INTERLEAVES arms: task k = (game k / 4, arm k % 4), so at 30 threads about
# 7-8 games x 4 arms are in flight at once and a manual stop "at 64 games" means
# 64-72 completed games per arm (kimi-k3-prereg-review.md section 4).  Stop
# conditions are operator-applied with compare.py --first N on the partial
# artifacts; the runner implements no stop logic.
